NOTES ON THE FINAL PROJECT CLOSEOUT PROCESS
Contact John Styba for questions/comments: john.styba@faa.gov or 406-449-5279
® Keep all items for a closeout in a "package" — this will prevent loss. Do not send in
the final pay request ahead of the package since we need to determine the final federal
share from the data included in the report before the pay request can be processed.
® There should be no "surprises" at this point in a project's life — those items should
have been discussed with the FAA project manager as they became known during the
life of the project. "Surprises" are significant conditions or results that we are not
aware of such as:
- large recovery or amendment needs of federal dollars
AIP 32 Grant
- changes to the specifications, such as in the area of acceptance testing
Amendment
- added work, change orders, or other costs not in the initial work scope
® Each Closeout Package consists of:
- As -Built Set of Construction Drawings - half size sheets, and one set cadd files.
V/
Do not bind the as -built sheets inside the report.
- 2 signed copies of the Final Payment Request - we need to send these in for
`�
processing thus do not bind them into the report — place a copy of the final pay
request with the summary of costs sheet
- Revised Pavement Evaluation Sheet — get the latest from the State System Plan
N/A
(for GA) or FAA project manager, then revise per your project.
- As -Built ALP: If project resulted in changes to the ALP (new taxiway, apron
N/A
expansion, etc.) an as -built ALP is required. In this case, send 5 sets of signed full
size blue line drawings with 2-CD's of CADD files. FAA will stamp and approve
and send back approved copy to Sponsor and Consultant (add more copies if more
than one sponsor, etc.). Place most recent revision date on main ALP sheet.
- Revised 5010 Airport Master Record Sketch and revised 5010 data (mark-up the
5010 with the changes) if project resulted in changes. Send this data to FAA as
NIA
early in the project as possible to allow for published changes to coincide with
finished development.
- Project Closeout Checklist — (see above). Note: this checklist is included so that
the author of the report is aware of the key elements that FAA addresses when
completing the federal portion of a project closeout. The Sponsor's Consultant
should be able to determine that the listed items, if applicable to this project, have
been properly addressed in the final report. Place completed checklist as the first
pages seen on the inside of the report.
® The Final Closeout Report requirements are included in Regional ANM Airports
Standard Handout per Engineering Guidance 99-03, dated 5/24/99. This guidance is
located on the FAA ANM Airport's Home Web Page: http://www2.faa.gov/arp/anm
Select Safety and Standards Branch, Construction, Construction, then "Standard
Handout for Final Report's" under "Policy and Guidance". Additions to the
`/
Regional Guidance for the HLN ADO include: (1) This Final Closeout Report
Checklist — fill out and bind this checklist in the front of the final report. (2) Final
Summary of Cancelled Warrants — see notes below.
® The consultant preparing the final report, needs to "check the numbers against each
other". This is called the "three -way -check". The report should contain a statement
✓
that this check has been made by the author.
- For construction costs, the final amounts must agree with each other on the final
payment request, final periodic cost estimate, and the summary of cancelled
warrants.
- For consulting fees, the final amounts must agree with each other on the final
payment request, approved engineering contact (including addendums), and the
summary of cancelled warrants.
Page 3 of 4
- For administrative costs, the amount requested on the final pay request must agree
with the cancelled warrant summary, and any agreement of pay such as an
✓
independent cost analysis. For those items that are simple in nature, such as
advertising costs or permit fees, just the warrant summary and the breakout of the
final payment request area of the final report need to agree.
® Explanation required for all costs claimed. The old time final reports were
✓
construction only, and gave little if any data on other fees claimed. The report must
now cover all claimed cost areas, including studies by the engineer that are included in
the grant. A narrative needs to be included in the report that further breaks out how
the line items of claimed costs on the final payment request were developed. "Other"
or "miscellaneous" costs without an explanation will cause that cost to be disallowed.
® Acceptance test results and payment impacts. Each specification area (P-152, P-208,
P-401, .....) has it's own acceptance testing requirements. In some cases, the material
must meet 100% of the requirement before the next step in construction can proceed.
Often, there are areas that must be re -worked to meet acceptance parameters. A
summary only of the test results is required to be included in the report. A statement
needs to be included in the report for the following:
- That the material met the acceptance test requirements. For the materials that do
✓
not have payment deducts for test results below certain values, a statement needs
to be added that the re -worked areas did meet acceptance requirements.
- For materials that do have payment deducts or bonuses due to acceptance test
N/A
results, a copy of the computer printouts, which show the pay determination, need
to be included in the report. A statement such as, "for P-401, a total of $$, were
ducted per the specification, from the contractors payments due to acceptance test
results falling below prescribed values. If re -tests were done, explain the impact
to the amounts paid to the contractor, including a copy of the computer printouts.
Contracts. Verify that a copy of the final signed contacts for this project is included
in the final report package. That includes, engineering, construction, equipment,
land appraisals, etc.. Often the only copy that was sent to FAA was a draft or unsigned
or preliminary copy. Our records must include an executed contract. This applies to
addendums or supplementary agreements as well. In the final report include:
- Copies of signed contracts, including the date executed in the narrative section of
the final report.
✓
- Include a summary of FAA concurrence for each contract: date of approval or
concurrence in award letter or e-mail reply.
`�
- For engineering contracts, include a discussion of the sponsor's independent cost
analysis and record of negotiation. State when this information was sent to FAA.
® Cancelled Warrant Summary. A Warrant is a payment method or "check" that a
Sponsor uses to make payments for elements of the project work. Include a summary
of cancelled warrants that lists the
® date, warrant number, party warrant is made out to, and the amount for each cost
claimed.
✓
® Group the type of work together and provide a sub total for each group (i.e.
Engineer, Contractor #1, Equipment, Associated Land Costs, Administrative).
✓
You must have a subtotal for each category or you cannot be able to complete the
"Three -Way -Check".
® Provide a total of all warrants at the bottom of the summary. Compare the sub
✓
totals and final total to amounts on the Final Payment Summary Worksheet (Page
6 of the Final Report) — this is part of the three-way check described above.
® Each division of work as explained above needs to have a total on the cancelled
✓
warrant summary sheet in order for this amount to be used in the "three-way
comparison". In the case where the final warrants have not been issued or
cancelled, yet the amount is known and fixed, include a line in the summar
Page 4 of 4
showing the amount and to whom, but leave blank the warrant number and date.
Follow-up the missing data with a revised sheet once the final data is known.
® Make sure there is a Maintenance Program included in the final report for all
development type projects (not needed for land, planning, orequipment type ants)
® Rounding Down. Make sure the final TOTAL federal dollars paid to or claimed by
NA
the sponsor are a whole dollar. The final federal share must be rounded down to the
nearest whole dollar.
® A signed Amendment letter, justifying a request for grant increase if allowable costs
NA
exceed the grant amount, should be included with the closeout package. Make sure the
amendment request is signed by the same entity (Sponsor) that is authorized to sign the
grant — then FAA can issue a letter of amendment if applicable. FAA will review the
request for a determination of reasonableness and eligibility. FAA does not guarantee
that funds will be readily available to cover such overages. Note: the Sponsor needs to
advise the ADO as soon as final projected costs indicate an amendment maybe needed
— do not wait until the project completion to identify amendment needs. Also, in the
case of significant cost under runs, the Sponsor needs to advise the ADO as soon as
significant recoveries of federal funds are projected while tracking the on -going
project budget.

Kalispell City Airport — North End Surfacing Improvements
1.1 Project Location and Airport Description
The Kalispell City Airport is located on the southside of Kalispell, between the
Highway 93 corridor and Airport Road. The airport lies within Section 20 of
Township 28 North, Range 21 West.
The airport has one paved runway with a total length of 3600 feet and 60 feet in
width. The runway has an orientation of 13/31. Other paved areas include a
bituminous asphalt apron and many taxiways providing access to the runway from
the apron and adjacent hangars.
Other facilities at the airport include; a rotating beacon, lighted windcone, several
private hangars, a T-hangar building, and automobile parking. Currently three new
hangars are currently being built, two of which are T-hangars. Services available
include 100-octane and jet aviation fuel. The apron area has thirty-three new tie
downs, all with coal tar emulsion treatment. Basic pavement markings are used on
the runway.
1.2 Improvements HistorX
In 1928, the City of Kalispell purchased 135 acres southwest of the community for
development of a municipal airport (the site of the existing Kalispell City Airport).
The airport was formally dedicated on July 3, 1929. In early 1966 the Kalispell
Airport Association was established to further develop the airport property. The
Association lasted for over 20 years, dissolving in 1986. During that time, many
improvements were made to the site, providing its current infrastructure of a paved
runway and adjacent taxiways. In 1999 the runway received a thin overlay with no
improvements conducted upon the existing taxiways. Overall the airport has seen
minimal improvements over the last 20 years until the addition of the new paved
taxiways and apron constructed in the summer of 2005. The purpose of this report
is to provide a complete narrative of the new construction commenced during the
summer of 2005.
1.3 Improvements Pro _gram
To meet the needs of a growing community, the City of Kalispell Airport Advisory
Board put into motion a plan to improve and expand the existing Kalispell City
Airport. This final report will cover project items completed during the "North End
Surfacing Improvements Project". The City of Kalispell has paid for 100% of the
funds required to complete the North End Surfacing Improvements Project. The
City of Kalispell is in the process of becoming eligible for federal aid from the FAA
to complete future improvements and expansions. Upon future FAA funding, a
total reconstruction of the existing runway is planned. It is the City's goal to
Final Report Page 3
Kalispell Cit�A Mort — North End Surfacing Improvements
ultimately be reimbursed for this project, through Airport Improvement Program
(AIP) funds, to the extent they are available once eligibility is obtained.
The City plans to expand the airport to the south, requiring land acquisition to
provide room for the proposed runway. Facilities constructed within this final
report were designed to match up with the future proposed facilities that will be
constructed once funding is acquired. The currently constructed project was
designed to serve a transitional facility between the existing airport design and the
proposed future and ultimate design planned for the Airport.
The Kalispell City Airport — North End Surfacing Improvements Project consisted
of the following items:
® Construction of a new asphalt apron with 33 aircraft parking locations
® Construction of a new taxiway system
® Installation of 18" RCP storm drain system providing site drainage
® Pavement markings
® Taxiway retroreflective markers
® Vehicle access control gate
® Access roadway
® Minor electrical improvements
Plans and Specifications were certified by the Sponsor and are included in
APPENDIX B.
A Pre -Bid conference was held on May 23, 2005 at 1:00 p.m. at the Kalispell City
Airport. Phil Porrini of Robert Peccia & Associates reviewed the scope of work,
goals, of the project and contract requirements for those present. Questions were
fielded and discussion of the project followed.
Administrative costs for this project were those costs normally encountered by the
Sponsor and which are reimbursable through an A.I.P. project. Administrative costs
include advertising for various aspects of the engineering and construction, plus costs
associated with implementing both a City and County Zoning Ordinances. They included
$125 to advertise a Public Notice regarding the Airport Redevelopment Plan, $37 to
advertise for DBE Goals, $774.65 to advertise for construction bids, $ 185 to advertise
for public hearings related to the Airport Redevelopment Plan. These costs are shown in
tabular form in Section 6.0 — SUMMARY OF PROJECT COSTS.
Engineering services were provided by Robert Peccia & Associates (RPA). The Sponsor
selected the firm on April 16, 2003. For the next two years, the Sponsor and the
Engineer, along with Federal and State agencies, awaited the outcome of negotiations and
court cases involving the radio station KGEZ, located south of the airport, along US
Final Report Page 4
Kalispell City Anport — North End Surfacing Improvements
Highway 93. Twin 300ft+ radio towers owned and operated by KEGZ are recognized
airspace penetrations at the Kalispell City Airport. These towers present a hazard to air
navigation and until they are removed the FAA is unable to fund airport improvements at
this facility.
Sponsor Certification for Selection of Consultants and is included in APPENDIX B. The
Agreement to Furnish Engineering Services was signed on February 22, 2005. Multiple
tasks orders were developed and those which are part of this project include:

Schellinger Construction, Inc. was encouraged to reach a specific Disadvantaged
Business Enterprise (DBE) participation goal of 3.48 percent for this project.
Schellinger Construction, Inc. met the goal by using three DBE contractors to
participate on this project. Promark, Inc. of Lolo, Montana applied all pavement
markings, Pavlik Electric of Missoula, Montana performed all electrical work and
tie down anchors and Kootenai Surveying of Libby, Montana performed all
surveying and construction staking services throughout the project.
Acceptance of the Notice of Award dated June 20, 2005 was acknowledged by the
Contractor on June 22, 2005. The Contractor was issued the Notice to Proceed on
July 7, 2005.
A listing of contractors who were sent personal invitations to bid on this project is
included in APPENDIX A of this document. The project was also publicly
advertised by the city in the Daily Interlake of Kalispell, Montana.
The bid tabulation is in APPENDIX A. Included in the bid tabulation is the
Engineer's Estimate.
Sponsor Certification for Equipment/Construction Contracts, included in
APPENDIX B, was obtained on July 6, 2005 for the Construction Contract dated
July 6, 2005 which was accompanied by the appropriate bid, payment and
performance bonds.
A Pre -Construction meeting was held on July 6, 2005. Two representatives of the
Contractor, two Engineering representatives, and one member of the Airport Board
were present. Multiple subcontractors were also present during the Pre -
Construction meeting. The owner of the three hangars being constructed north of
the planned apron was also present.
5.2 Engineer's Construction Narrative
5.2.1 Earthwork
Topsoil was removed from the locations of the new taxiways and apron and
stockpiled outside the construction limits with two scrappers. The topsoil was
stockpiled along the northern and western sides of the apron as well as east of
the proposed clean waste fill area. Observed topsoil depths ranged from 6 to
14 inches, averaging at 10 inches in depth over the site. All excavation and
embankment areas were stripped to root zone depth.
Excavation of the native soil was accomplished by the use of two scrappers.
Excavated material was placed on the embankments and compacted with a
smooth -drum roller as directed by the Construction Management Plan. Extra
native soil that was cut from the apron was placed in the clean waste fill areas
and compacted with a smooth -drum roller.
Final Report Page 6
Kalispell City Airport — North End Surfacing Improvements
During the taxiway topsoil and unclassified excavation removal over the
northern portion of the project, many areas composed of native soils began to
"pump" or developed a "waterbed" effect. Many of these native lean clay
subgrade soils, that were planned to support the new taxiway pavements, were
10% above their optimum compaction moisture, causing them to "pump"
easily under the loading of construction equipment. It became apparent that
much of the lean clay was not going to be able to support the equipment that
would be used to build the new pavements surfaces and that this saturated
material would need to be removed.
Change Order #1 was presented by Robert Peccia and Associates and approved
by the City on July 28, 2005, for the contractor to excavate 2 to 3 feet deep in
the areas that had developed the pumping soils. Dryer, on -site, lean clay,
excavated from the apron, was used as replacement material. The material was
placed in one lift, averaging in 2 to 3 feet in thickness over separation fabric.
Although many areas responded well to the muck excavation exercise by
greatly reducing or eliminating subgrade pumping problems, several areas
were still pumping and continued to threaten the constructablity and stability of
taxiway pavement sections. Additional efforts to shore up the subgrade soils
were needed before the placement of subbase and base course gravels could
commence.
Change Order #2 was presented by Robert Peccia and Associates and approved
by the City on August 19, 2005, for the addition of a Tensar BX-1200 geogrid
material to be at the top of the newly placed subgrade, just before placement of
the subbase gravel section. Taxiways B, C, D, & E along with large sections of
Taxiway A received geogrid. Depending on the severity of the subgrade
pumping, one of the following two gravel sections were placed upon the
geogrid. In many locations a 16" section of P-208 was placed and compacted
in one lift. In other locations, a 12" section of P-154 was placed and
compacted in one lift and followed with a 4" section of P-208 being compacted
as a second lift. The geogrid proved to work very well, shoring up the
underlain subgrade soils, providing a stable gravel section for the taxiway
pavements.
All subgrade and embankment areas, unaffected by subgrade pumping, were
either found to have acceptable compaction, grade and smoothness, or they
were reworked until acceptable results were achieved. All subgrade and
embankment areas affected by the subgrade pumping received geogrid and
modified gravel sections as need to provide required stability for taxiway
pavements. See APPENDIX D, Construction Management Plan for testing
frequencies and summary of results.
High daily temperatures with little to no rain and daily 10 to 15 mph winds
from the Southeast resulted in very dusty conditions at times. The Contractor
Final Report Page 7
Kalispell City Airport — North End Surfacing Improvements
continually watered the areas that were being traveled over and worked to help
keep dust down during earthwork operations.
The equipment used to complete the earthwork included:
® 2 — Caterpillar, 627G Scrapper
® 1 — Caterpillar, 615 Water Wagon
® 1 — Komatsu, 400 Excavator
® 1 — Komatsu, PC 30OLC Excavator
® 1 — Caterpillar, 14G Motor Patrol Grader
® 1 — Ingersoll-Rand, 150 Smooth Drum Roller
® 1 — Ingersoll-Rand, 200 Smooth Drum Roller
® 1 — Caterpillar, D8R Dozer
® 1 — Caterpillar, D6 Dozer
* 1 — Komatsu, WA 380 Loader
® Numerous Dump Trucks
5.2.2 Culverts and Drainage Improvements
Two existing catch basins, located along the new alignment of Taxiway `E'
near station 14+50, were removed as shown on the plans on July 20, 2005.
Construction of an 18" RCP storm drain alignment `A' started on July 21, 2005
and was completed on August 2, 2005. The Contractor started construction of
the alignment at the north, down gradient end and worked back to the south.
The storm drain was installed at a 0.20% slope, providing drainage to the north
as shown on the plans. The grade was controlled with an internal pipe laser
and checked periodically with a laser level to maintain positive grade.
Alignment was controlled with a transit station and further followed with the
internal pipe laser. The alignment was previously staked out by the surveyor
before installation. An excavator continually cleared topsoil and native soils
down to an elevation of 6" below base of storm drain pipe. The excavator
would then place a 6" layer of 3/a" crush bedding material into the trench and
place the reinforced concrete pipe upon it. The pipe was then set to grade and
backfill half way up the sides with 3/a" crush and compacted. The 3/a" crush
was watered before compaction and tested for compaction as needed. Flared
End Terminal Sections (FETS) with trash covers were installed at both ends of
the alignment.
After the 18" storm drain alignment `A' was constructed, it was covered with
on -site embankment materials to a depth of 6" over the top of the pipe with
maximum 6:1 slopes extending outward. A 6" layer of topsoil was placed
upon all disturbed areas following with seeding, fertilizing and mulching.
Four 12" reinforced concrete pipe storm drain laterals were installed westward
from several of the 18" RCP storm drain alignment `A' manholes. The laterals
pass under Taxiway `A', collecting run-off from the site in several locations,
Final Report Page 8
Kalispell City Airport — North End Surfacing Improvements
transporting it to the main alignment `A' and ultimately to a city storm drain
inlet at the intersection of Airport Road and 18`h Street West. FETs with trash
guards were installed at the inlets of all four laterals.
Additional reinforced concrete pipe culverts were place under the Access Road
at two locations, under Taxiway `F' at two locations and also under taxiway `G
at two locations. Drainage ditches were installed between the culverts,
providing positive drainage for the western and southern portions of the site.
Equipment used to complete the culvert and drainage improvements included:
® 1 — Komatsu, PC 300LC Excavator
® 1 — Komatsu, WA 380 Loader
® 1 — Caterpillar, D8R Dozer
® 1 — Caterpillar, D6 Dozer
® 1 — Sky Trak Forklift
® 1 — "Jumping Jack" Compactor
5.2.3 Apron Subbase and Base Course
Subbase (P-154) and base course (P-208) samples were taken from stockpiles
at the gravel pit or material on -site to determine Proctor values. Subbase
material was imported and placed only in areas of new construction. A
separation fabric was placed between subgrade and subbase in all locations
of new construction.
Construction of the apron continued once the subgrade was cut and compacted
to planned elevations. The contractor laid out multiple rolls of separation
fabric with a 2' minimum overlap between the rolls in preparation of the P-
154. On July 28, 2005, the contractor started to haul in P-154 subbase with
several belly dump trucks onto the site. The contractor began to place the
material along the southern edge of the apron and pushed the gravel out to the
north with a grader, maintaining a 12" lift of gravel under all equipment. This
proved to be quite affective in not disturbing the fragile subgrade. The apron
placement of P-154 was completed on August 4, 2005. Density and moisture
content tests were taken frequently throughout the placement of the P-154
material to provide the contractor compaction guidance.
The P-154 was watered continually and compacted with two rollers. Kootenai
Surveying placed a grid of "blue tops" down for final grading and compaction.
Final acceptance compaction tests were taken by the engineer on August 6,
2005.
Placement of P-208 base course followed. The material was hauled to the site
in belly dump trucks and placed on the apron using the same procedure as used
to place the P-154. The P-208 was placed in a single 4" lift and compacted.
During placement, the P-208 was continually watered and compacted. As the
Final Report Page 9
Kalispell City Abort — North End Surfacing Improvements
contractor approached grade, Kootenai Surveying "blue topped" the apron,
providing final visual guidance for final grading. Density and moisture content
tests were taken frequently throughout the placement of the P-208 material to
provide the contractor compaction guidance. Final acceptance compaction and
string line testing were taken by the engineer on August 23, 2005.
All subbase and base course was either found to have acceptable compaction,
grade and smoothness, or it was reworked until acceptable results were
achieved. See APPENDIX D, Construction Management Plan for testing
frequencies and summary of results.
Equipment used to complete the subbase and base course included:
® 1 — Caterpillar, 14G Grader
® 1 — Ingersoll Rand, 150 Smooth Drum Roller
® 1 — Ingersoll Rand, 200 Smooth Drum Roller
® 1 — Water Wagon
® Numerous Belly Dumps
5.2.4 Taxiway Subbase and Base Course
During earthwork operations, many taxiways developed unstable subgrade
conditions. Two different gravel sections were used to provide stability for
future taxiway pavements. Final earthwork subgrade digouts were completed
on August 15, 2005. The subgrade soils removed were replaced with dryer on -
site embankment materials excavated from the apron and surrounding areas.
This work was directed under Change Order #1.
One of the following two gravel sections was implemented during taxiway
construction and directed by Change Order #2. In many locations, the original
planned P-154 section of 12" was placed and compacted in one lift and
followed with 4" of P-208 to the planned base of pavement elevation. All
sections that received this typical section received an underlain separation
fabric, with some sections receiving geogrid. Geogrid was used sparingly and
placed in only those areas that needed it.
In other locations, a modified 16" section of P-208 was placed and compacted
in one lift to the planned base of pavement elevation. Using the more angular
P-208 material as a substitute to the P-154 provided a stronger section in the
areas of continued subgrade pumping. Separation fabric and geogrid were
place beneath all modified gravel sections.
Kootenai Surveying provided blue tops upon all taxiways for final grading and
compaction. No vibratory compaction was used upon any of the taxiway
gravel section in fear of further subgrade disturbance. Taxiway gravels were
continually watered and worked as static roller compaction proceeded.
Final Report Page 10
Kalispell City Airport — North End Surfacing Improvements
The first round of taxiway base course acceptance testing failed. Taxiways B,
C and D all yielded final P-208 grade elevations of 1" to 3" below plan
elevations. Source of the error was determined to be from a roller operator
continually rolling over the "blue top" hubs, pushing grade control down in
elevation. Affected taxiways were "blue toped" a second time and final grade
was achieved. Taxiway final density and string line testing were preformed by
the Engineer between August 23, 2005 and September 2, 2005.
All subbase and base course was either found to have acceptable compaction,
grade and smoothness, or it was reworked until acceptable results were
achieved. See APPENDIX D, Construction Management Plan for testing
frequencies and summary of results.
Equipment used to complete the subbase and base course included:
® 1 — Caterpillar, 14G Grader
® 1 — Ingersoll Rand, 150 Smooth Drum Roller
® 1 — Ingersoll Rand, 200 Smooth Drum Roller
® 1 — Caterpillar, D8R Dozer
® 1 — Caterpillar, D6 Dozer
® 1 — Water Wagon
® Numerous Belly Dumps
5.2.5 Plant Mix Bituminous Pavement
Placement of Bituminous Pavement commenced on August 31, 2005 with the
paving of the test strip. Taxiway E was chosen as the location of the test strip,
providing a 25' wide, 315' long section of pavement. Schellinger Construction
began placing the first ribbon of the test strip at 6:lOpm. The first ribbon was
allowed to cool down to provide a longitudinal cold joint. The cold joint was
saw cut and tacked before the placement of the second ribbon. The second
ribbon was started at 8:15pm and finished by 9:00pm, completing the test
section. As specified tests were conducted on the three samples randomly
taken by GMT Engineering, the Contractor made claims that a sampling error
had occurred, resulting in slightly higher than acceptable air voids. The
Contractor instructed GMT, their testing agency, to revisit the site and take
additional 6" diameter cores from the finished mat. The cores were taken for
retesting purposes in the approximate locations that the original samples for
sublots 1 and 2 were taken. The cores were reheated to sampling temperatures
and retested. The retests produced higher Marshall Density values, yielding
lower air voids, supporting the Contractors claim that there was a sampling
error. The retests and test strip was accepted and the Contractor was allowed
to proceed with full production paving.
Full production paving commenced on September 2, 2005 upon Taxiway B, C,
D, and E. Paving continued from September 6, 2005 to September 9, 2005,
finishing all of the taxiways, the access road and the southern two thirds of the
Final Report Page 11
Kalispell City Airport — North End Surfacing Improvements
apron. Two inches of rainfall, over the following weekend, pushed the final
paving of the apron to September 14, 2005, with final patch work and small
apron overlay paving (near Diamond Aire) to September 20, 2005.
Mix was delivered to the site from a hot plant north of Kalispell (15 miles from
the airport) in end -dump trucks. A small bobcat was used for incidental
movement of mix, especially at the ends of each ribbon. A paving machine
with a sonic sensor apparatus was used to place all pavements. As the
pavement was placed, the crew continually checked the loose depth of the
asphalt, making adjustments as needed. All minor problems were resolved
quickly by adjusting the screed, hand shoveling mix and raking mix. All cold
joints were cut with a colter wheel and coated with a bituminous tack coat to
improve adhesion. The surface course was compacted with heavy steel -drum
breakdown roller and then finished with a lighter steel -drum roller after
cooling. Compaction was monitored closely with a nuclear gauge operated by
the contractor's testing agency.
Quality control testing was performed by GMT Engineering, of Missoula
Montana, an ASTM D-3666 certified testing laboratory. CMG Engineering, of
Kalispell Montana also participated in quality control testing under the
supervision of GMT Engineering.
All pavement was either found to have acceptable oil content, air voids,
compaction, thickness, grade and smoothness, or adjustments were made to the
asphalt mix, placement methods, or there was a payment deduction. All lots
received 100% payment. See APPENDIX D, Construction Management Plan
for testing frequencies and summary of results.

5.2.6 Tie Down Anchors, Electrical Improvements and Taxiway Markers
Pavlik Electric, Inc. of Missoula, Montana was the electrical subcontractor for
Schellinger Construction, Inc. They were responsible for the electrical
improvements, new retroreflective taxiway markers and concrete apron tie
down installation.
Prior to paving the apron, Pavlic Electric, Inc. augured multiple three feet deep,
18" diameter holes into the previously place P-154 and P-208 base gravels for
Final Report Page 12
Kalispell City Airport — North End Surfacing hnprovements
the concrete tie -down anchors. Sona-tubes were place in the holes, following
grading and compaction of P-208 around all of the tubes. The sona-tubes were
caped with ply -wood covers during paving and relocated and removed prior to
asphalt compaction. Following the paving, the tie -downs were suspended into
place and concrete was poured around them matching the finished grade of the
asphalt. One tie -down out of each set of 3 was grounded by a #8 AWG copper
wire with attached 8' long copperweld ground rod. Each grounded tie down
was stamped "GROUND".
Equipment used to complete the Tie -Down Anchors were:
® 1 — Bobcat with 18" augur
® 1 —John Deere Backhoe
® Jumping Jack Wacker
Pavlic Electric installed all of the retroreflective taxiway markers. Pavlic
Electric, Inc. also installed the electrical conduit to the proposed Airport
Managers office facility and Access Control Gate. Pavlic Electric, Inc. also
installed several ducts for future use under several taxiways prior to paving.
Duct markers were installed in the finished asphalt mat, providing visual
guidance for the locations of these new ducts as well as several exiting ducts.
Pavlic Electric, Inc. installed all electrical improvements needed to supply
power to the new Access Control gate as well as conduit for the data
communication cables needed to control the gate.
5.2.7 Pavement Markings
Promark, Inc. of Missoula, Montana applied all of the pavement markings. All
taxiway lines were painted yellow and applied at full rate on September 23,
2005. All applications included the use of reflective glass beads to enhance
pavement markings for nighttime operations.
Equipment used to complete the pavement markings were:
• 2 — Hand Cart with Pressurized Paint Gun
5.2.8 Other Improvements
Other improvements included the following: relocation and installation of
chain link fencing and an Access Control gate; disking topsoil, applying
fertilizer, seed and mulch for all disturbed areas was completed by HydroTech,
Inc. of Kalispell, Montana.
5.2.9 Change Orders and Suspensions of Work
Three Change Orders were submitted and approved during the course of this
project. The Change Orders are as follows:
Final Report Page 13
Kalispell City Airport — North End Surfacing Improvements
Change Order #1, Approved by the Owner on July 29, 2005 to perform the
removal and replacement of unstable taxiway subgrade soils. Final total
amount billed for Change Order #1 quantities was $47,758.50.
Change Order #2, Approved by the Owner on August 19, 2005 to further
stabilize taxiway subgrade soils in preparation of P-154 and P-208 gravel with
the installation of BX1200 geogrid. Several taxiways received modified gravel
sections, where the P-154 section was replaced with P-208. Final total amount
billed for Change Order #2 quantities was $114,930.86, however, reductions
for P-154 replacement (-$57,694) and P-602 Prime Coat elimination (-
$13,560), made the net change $43,676.86. The final quantities for Base Bid
work reflect these reductions and have lowered the total cost accordingly.
Change Order #3, Approved by the Owner on September 22, 2005 to develop
Vehicle Gravel Parking Pads at several Hangar Sites. Final total amount billed
to Change Order #3 was $5,355.00.
One suspensions of work was issued on August 12, 2005 due to rain.
Schellinger Construction performed very little work on September 12 and 13,

5.7 Completion
5.7.1 Planned / Final Quantities and Costs
APPENDIX A contains the quantities and costs of the construction related
items in this project. Those items that exceeded or were under the planned
quantity by more than ten percent are discussed in detail below. Items within
ten percent of the estimate, but not exactly at planned quantity are such
Final Report Page 15
Kalispell City Airport — North End Surfacing Improvements
because of normal variance typical in construction contracts unless otherwise
noted.
Item # 102 —Unclassified Excavation (P-152): This item was 33.7% over the
planned quantity (+4,732 CY). The amount of Unclassified Excavation
changed due increases required to build the planned typical sections. The
unclassified excavation estimates for the Hangar Access Taxiways (B, C, D, E,
F & G) along with the Access Road were provided to the Contractor by
Addendum during the bidding process, but were not added into the total
Unclassified Excavation quantity on the Bid Proposal Sheet. After further
review of the design notes for this project, it was determined that the increase
was required to build the project as designed.
Item # 110 —Subbase Course (P-154): This item was 19.0% under the planned
quantity (-2,135 CY). The amount of subbase course was decreased due to a
P-208 material replacement under the direction of Change Order #2. It was
determined advantageous through on -site observations that the more angular P-
208 material, when placed in a single lift over the BX1200 geogrid, would
provide a stronger taxiway section. The stronger section was needed in many
locations to successfully bridge over troublesome subgrade areas.
Item # 112 — Bituminous Prime Coat (P-602): Planned placement of the prime
coat was suspended with the approval of Change Order #2. The Contractor
used only 1 ton of prime coat over the entire project during an asphalt overlay.
Item # 114 — Bituminous Asphalt Material, Asphalt Cement (P-401): This item
was 20.2% under the planned quantity (-64.3 tons). The planned quantity was
based on 7% asphalt cement content and mix design designated asphalt content
of 5.6%.
Item # 118 — Trenching for PVC Ducts (L-108): This item was over 60.0%
from planned quantity amounts (+75 FT). During the project, 75 feet of
existing utilities were needed to be lowered to provide adequate clearance for.
new taxiways. As these utilities were lowered, the cost of the work was
accounted for within this item.
Item # 126 — Seeding, Fertilizing & Mulching (T-901 & T-908): This item was
over by 190.0% from planned quantity amounts (+9.5 acres). This overage is
to account for the extra area of disturbance that was not incorporated into the
Proposal. It was determined that the 5.0 acres that was planned to be seeded,
fertilized and mulched needed to be increased to 14.5 acres.
Item # AA-2 — Manhole Adjustments (D-701): This item was 100% over the
planned quantity. One extra manhole was adjusted in front of Diamond Aire
after a small overlay to an existing apron was requested by the Owner. The
Final Report Page 16
Kalispell City Airport — North End Surfacing Improvements
extra adjustment was not initially planned but was decided to be performed
during the final inspection.
Item # AA-6 — Bituminous Prime Coat (P-602-5.1): Planned placement of the
prime coat was suspended with the approval of Change Order #2.
Item # AA-8 — Bituminous Asphalt Material, Asphalt Cement (P-401): This
item was 20.4% under the planned quantity (-4 tons). The planned quantity
was based on 7% asphalt cement content and mix design designated asphalt
content of 5.6%.
Item # CO-1-1 — Muck Excavation and Haul: This item was 50.3% over the
originally estimated change order quantity (+1,813 CY). Much larger portions
than original quantities tabulated in Change Order #1 were removed to achieve
desired stability. Locations of greater than planned muck excavation were
portions of Taxiways A, E, F and G.
Item # CO-1-2 — Fill Replacement in Sub -excavate Areas: This item was
50.3% over the planned quantity (+1,645 CY). Due to larger muck excavation
quantities, more fill replacement material was needed to fill in all mucked -out
areas.
Item # CO-1-3 — Subsurface Separation Fabric: This item was 66.0% over
planned quantity (+2,033 SY). Due to larger than expected muck excavation
quantities, more subsurface separation fabric was needed to cover all mucked
areas.
5.7.2 Liquidated Damages
The original contract specified 45 calendar days for construction. Ten (+10)
additional contract days were granted for the construction of Change Order #1.
Seven (+7) additional contract days were granted for the construction of
Change Order #2. Six (+6) additional contract days were granted for the
construction of Change Order #3. One (+I) additional contract day was
granted for poor weather on August 12, 2005. The Contract Time was thus
extended to 69 calendar days. The Contractor was granted "substantial
completion" on October 6, 2005 (91 calendar days after the NTP was issued,
84 calendar days after the construction started) when the new facilities were
useful and usable for the Owner to use. No liquidated damages where charged
to the Contractor for contract time, as it was determined that the Contractor had
diligently worked through several unforeseen circumstances that resulted in
two significant Change Orders.
The Contractor was not assessed with liquidated damages for Resident Project
Representative's (RPR) time over 40 hours/week.

8.1 Construction Management Plan
Included in APPENDIX D of this document are forms from the CMP that determine
the testing frequency of P-154, P-208 and P-401. The forms have been updated to
include actual testing frequencies.
8.2 Acceptance Test Summary Sheets
Acceptance testing included testing of subgrade (P-152), subbase (P-154), base
course (P-208) and plant mix bituminous pavement (P-401). The Contractor's
subcontracted testing lab performed all plant mix bituminous pavement laboratory
tests.
Calculations of the "percentage of materials within limits" (PWL) for the P-401
plant mix bituminous pavement and the associated asphalt cement contents were
calculated by the Engineer and are included in APPENDIX D. All lots had
acceptance test results for all specified criteria with resulting PWL's allowing for
100% payment for all plant mix bituminous pavement and asphalt cement. Sample
standard deviations were quite low, densities high and quality indices high for all
the plant mix bituminous pavement.
8.3 Control Tests Summary Sheets
Control testing included quality control monitoring of P-401, plant mix bituminous
pavement, and core samples of plant mix bituminous pavement.
The P-401, plant mix bituminous pavement, was tested during production for
asphalt content, aggregate gradation, stability, flow, unit weight, temperatures,
VMA and air voids. Mat densities and core thicknesses were measured for the
completed P-401 mat. Control tests showed a consistent mix at, or very near, target
values and within specifications. All control testing was performed by GMT
Engineering, Inc. of Missoula, Montana, an ASTM D 3666 accredited laboratory.
8.4 Mix Design Summary
The mix design for the plant mix bituminous pavement is included in APPENDIX C
followed with the refining company's certificate of asphalt cement properties in
APPENDIX D. IIKM Engineering, Inc. of Billings, Montana provided the mix
design to the Prime Contractor for the plant mix bituminous pavement. The mix
design grading band was within specifications. Several additional tests were
requested by the engineer to complete the design per FAA specifications. The
requested tests were provided to the engineer in a timely manor and the design was
approved for production.
