1. SCOPE OF WORK
A. Narrative
The scope of work for this project includes reconstruction of the east apron and regrading of the runway safety area (RSA) on the south end of Runway 14/32. The scope of the project will consist of two schedules of work split into two phases. Schedule I (Phase 1) is Apron Reconstruction northeast of the terminal building; and Schedule II (Phase 2) is Runway Safety Area Grading on the Runway 32 end.
The apron reconstruction part of this project will remove and replacement the existing concrete apron pavement including pavement demolition, lime stabilization of the subgrade, surface drainage, and pavement markings.
Figure 1: Project Area Exhibit
This project shall have the following schedules described below in more detail:
Schedule I – Phase 1: Apron Reconstruction This schedule will include the reconstruction of the northeast apron pavement and the subsidiary items associated with this new pavement, excluding the new pavement in front of the fuel farm. The pavement area adjacent to the fuel tanks was reconstructed last year to minimize the impact to fueling operations during the reconstruction of the remainder of the apron. Fueling operations will remain operable during project calendar days. Construction for this schedule is identified as Phase 1. Schedule I – Phase 1 shall be completed concurrently with Schedule II – Phase 2 within the 75 calendar days associated with the award of Schedule I. The closure of Runway 14/32 is not necessary for Schedule I construction; however, the runway shall be closed for the duration of Schedule II – Phase 2.
Issued for Bid March 30, 2017 4 Project No: 16-002A-1
Schedule II – Phase 2: Runway Safety Area Grading This schedule will consist of grading the Runway 32 Safety Area to meet design standards. The work area surrounds runway end 32. Construction for this schedule is identified as Phase 2. Schedule II – Phase 2 work shall be completed in 10 days concurrently with Schedule I – Phase 1 work. Runway 14/32 will be closed for the duration of Schedule II – Phase 2 construction.
B. Unique and Unusual Site Conditions
There are no unique or unusual site conditions encountered on this project.
C. Age of the Existing Pavement
The Portland cement concrete apron at Northwest Missouri Regional Airport was constructed in 1985. This was the last major maintenance/rehabilitation to the pavement. At the last MoDOT Pavement Condition Index (PCI) inspection in 2011, it was reported that there is high-severity joint seal damage and low-to-medium-severity LTD cracking, faulting, and shattered slabs. Joint spalling, shrinkage cracking and corner breaks were also noted.
D. Current PCI Value
The most recent pavement evaluation, May 2011, determined that the PCI value for the northernmost apron section was 60, which indicates the need for rehabilitation. At the time of the 2011 inspection, it was projected that with no maintenance and due to load, climate, durability and other factors, the PCI value in 2017 will likely be 49.

3. LIFE CYCLE COST ANALYSIS
A Life Cycle Cost Analysis was performed for the apron pavement to evaluate the 20-year costs comparing the reconstruction of this area with a Portland cement concrete pavement section versus a bituminous pavement section. Based on the analysis for a 20-year design life the Concrete Alternative is 12% cheaper than the Asphalt Alternative. The reconstruction of the apron will be using a Portland cement concrete pavement section.
The Life Cycle Cost Analysis in included in Appendix D of this report.
A. Asphalt Alternative:
5.0 inches of Bituminous Paving Course (P-401)
7.0 inches of Aggregate Base Course (P-209)
9.0 inches of Fly Ash Treated Subgrade (P-158)
B. Concrete Alternative:
6.0 inches of Portland Cement Concrete Pavement (P-501)
6.0 inches of Aggregate Base Course (P-209)
9.0 inches of Fly Ash Treated Subgrade (P-158)
The life cycle cost comparison favors the new rigid pavement on base course section due to the 20-year overall cost, including the proposed maintenance and rehabilitation of each pavement section. The analysis takes into consideration initial cost and maintenance of each section over a 20-year time-period.
The comparison yielded the following results:
Initial Costs - Asphalt Alternative $46.48 per Square Yard
Initial Costs - Concrete Alternative $66.87 per Square Yard
20 Year Lifespan Cost - Asphalt Alternative $81.40 per Square Yard
20 Year Lifespan Cost - Concrete Alternative $71.41 per Square Yard
See Appendix D for supporting documentation for the Life Cycle Cost Analysis.
4. DESIGN STANDARDS
The Northwest Missouri Regional Airport apron, RSA and other items associated with the reconstruction of this pavement are designed to meet the requirements and specifications of MoDOT Aviation, the 2011 Missouri Standard Specifications Book for Highway Construction, and the most current FAA Advisory Circulars. The new proposed apron pavement grades will meet the pavement surface grading requirements not to exceed a 2% slope. The RSA will tie into existing areas and will vary between 1.5% and 5%. The Advisory Circular 5300-13A Airport Design was referenced for establishing the
Issued for Bid March 30, 2017 8 Project No: 16-002A-1
components of this project. The geometry used for design of aircraft taxiing pavements is that of the Taxiway Design Group (TDG) 2. The runway is designed to meet the requirements of a Runway Design Code (RDC) for a B-II runway.
The apron construction shall include taxilane centerline and tie down pavement markings. Included in this project will be the painted hold bar and centerline marking for the connector taxilane at the southernmost portion of the airfield. The centerline will connect in with the centerline of the connector taxilane just north, that was completed in the Runway 13/31 reconstruction project of 2016. These markings shall comply with the Standards for Airport Markings, AC 150/5340-1L.
To determine operational usage of pavement on this northeastern portion of apron pavement, autoturn was utilized. A group I and group II aircraft path was reviewed for use over the apron area for operations such as refueling, taxiing to and from the runway, parking at the tie down locations and taxiing to hangars. Upon review of the pavement usage, it has been determined that the bulk of this pavement is eligible for the project up to 27 feet from each hangar. The 27 feet of pavement in front of the existing hangar is considered part of the building and building eligibility rules apply. Pavement removal and tie-in will be much easier at existing concrete joints. Upon consideration of existing concrete joint layout, the actual width reconstructed along the northeast edge of the apron will be within approximately 22’ of the hangar entrances, at an existing concrete joint. Due to larger panel sizes, the south border of the apron in front of the larger City-owned hangars will be reconstructed to approximately 15’ in front of the hangar. These slight expansions of the eligible area will help to reduce construction costs for saw-cut, joint sealant, and removal of partial panels.
Project pavements were analyzed and designed to ensure positive drainage of all pavement surfaces. All portions of the proposed airfield pavement will be situated below the Primary Surface, Transitional Surface and/or Approach Surface, as required by CFR Part 77.

5. ENVIRONMENTAL PROTECTION
On December 28, 2016, a letter of environmental clearance was submitted to MoDOT in place of a Categorical Exclusion document due to the small scope of potential impact. The new pavement for this project will replace existing pavements and not disturb additional area. Additionally, the regraded RSA will minimally impact the existing environment. This project is categorically excluded per paragraph 5-6.4(e) of FAA Order 1050.1F as referenced in the MoDOT categorical exclusion which was received by email on January 25, 2017.
6. SOILS AND GRADING
A geotechnical study was prepared by TSi Engineering, Inc in November 2014 for Runway 14/32 and the apron to summarize the geotechnical findings. The conclusions and recommendations of their study are presented in the report titled, Report of Subsurface Exploration and Geotechnical Engineering Evaluation, Northwest Missouri Regional Airport, Maryville, MO, dated December 15, 2014. The entire report can be found in Appendix C of this report. This geotechnical study included subsurface exploration to determine soil properties and provided geotechnical recommendations for the pavement design criteria and associated geotechnical recommendations in accordance with the current AC 150/5320-6.
As part of the subsurface exploration portion of the geotechnical study, TSi completed a total of two pavement borings at locations associated with the apron reconstruction.
A laboratory testing program was completed to determine the soil characteristics encountered during the subsurface exploration. Testing included classification, Atterberg Limits, natural moisture content, California Bearing Ratio (CBR), Soil Reaction Modulus (k), and swell/consolidation testing.
Soil conditions encountered at Boring No. B-07 generally consisted of 5.5” of Portland cement concrete and gray, fat clay (CH). Soil conditions encountered at Boring No. 8 generally consisted of 6” of Portland cement concrete and brown, fat clay (CH). Soils from both locations were determined to have significant swell potentials. The report concludes that high plasticity clays should be over-excavated 18” and replaced with Low Volume Change (LVC) fill material. On-site soil treated with lime would qualify as LVC fill material. In follow-up conversations between Ryan Lorton of Jviation and Michael Schmitz of TSi, flyash was allowed to be substituted for lime. Since 9” of flyash treatment worked well on the runway and taxiway projects with similar soils, it will be utilized on the apron project as well.
Issued for Bid March 30, 2017 10 Project No: 16-002A-1
7. DRAINAGE
The original storm drainage system for the northernmost apron was completed during construction of the apron in 1985. The apron area has adequate site drainage capability.
As the reconstruction of the apron will not stretch beyond the footprint of the existing apron, pavements will not significantly impact the existing runoff basins or drainage characteristics.
A. Rainfall and Runoff
Evaluation of rainfall data was considered in the original design of the apron and appears to be functioning adequately. Re-evaluation is not required by this scope of work.
B. Storm Drains/Structure Design
Storm sewer inlets and culverts have been designed to capture and convey the 100-year storm.
C. Detention Pond Design
This section is not applicable for this project.
D. Special Measures Taken to Mitigate Wildlife Hazards
This section is not applicable for this project.
8. PAVEMENT DESIGN
A. Existing Northeast Apron Pavement
The existing concrete apron portion will be removed in entirety due to the failure and age of the material. Information gathered from Missouri Department of Transportation’s multimodal operations division (aviation section) states that the pavement is over 30 years old. Pavement core results indicate the pavement section consists of 5.5 to 6 inches of Portland cement concrete pavement underlain by soil.
This apron portion of pavement is experiencing LTD cracking, joint spalling and joint sealant damage.
B. Design Assumptions
For the apron pavement a pavement design was performed using the FAA’s pavement design software, FAARFIELD. The geotechnical report completed by TSi Geotechnical recommended the use of a subgrade k value of 100pci based on a CBR of 3. Due to the existing high plasticity clays (CH), the geotechnical engineer also recommended that these materials be replaced with Low Volume Change (LVC) fill. In addition, the geotechnical report also recommended a minimum 6-inch layer of P-209 crushed aggregate base course be utilized to allow drainage. The remainder of the 9 inches of LVC fill will be addressed by use of fly ash treated subbase.
Aircraft included in the fleet mix consist of single-wheel aircraft weighing 12,500 pounds or less with a few operations of heavier aircraft, all under 60,000 pounds. The Federal Aviation Administration AC 150/5320-6F, Airport Pavement Design and Evaluation, requires that ASTM D 698, Standard Test Methods for Laboratory Compaction Characteristics of Soil Using Standard Effort, be utilized for soils beneath pavements for aircraft weighing less than 60,000 pounds.
Issued for Bid March 30, 2017 11 Project No: 16-002A-1
C. Fleet Mix and Number of Departures for Each Aircraft
Annual departures were based on the 2015 AirNAV data and tenant information provided by the airport personnel. The annual growth rate was estimated from the AirNAV data and past historical operations numbers.
The assumed fleet mix consisted of the following:
No. Name Gross Wt.
lbs Annual
Departures 1 Single Whl-12.5 12,500 3,000 2 Single Whl-10 10,000 2,400 3 Learjet-35A/65A 18,000 100
D. FAARFIELD Pavement Design Output
Per the FAA AC 150/5320-6F Airport Pavement Design and Evaluation, all pavement designs will be computed with the FAA design software for rigid and flexible pavements (FAARFIELD). Based upon the design data presented above, the following pavement sections have been computed by FAARFIELD software with a design life cycle of 20 years.
The FAARFIELD results were as follows:
Figure 6: FAARFIELD apron pavement section
The actual section will include 6 inches of crushed aggregate base course (P-209) per the recommendation of the geotechnical report for providing drainage below the PCC pavement. The remainder of LVC will be addressed by using fly ash stabilization resulting in a proposed 9-inch thick fly ash treated subbase (P-158) below the proposed 6 inches of crushed aggregate base course (P-209).
Issued for Bid March 30, 2017 12 Project No: 16-002A-1
E. Frost Design
The geotechnical investigation concluded the subgrade material onsite beneath the pavement section is primarily fat clay (CH) with a plasticity index averaging 41. The Frost Group for these types of materials is Frost Group 3 (FG-3).
Historically, a frost depth of 32 inches has been utilized at the Airport. AC 150/5320-6F recommends two methods to contend with frost in FG-3 soils; Complete Frost Protection and Limited Subgrade Frost Penetration. Due to historical frost design and the lack of frost heave in the existing 30-year-old pavement, this project will utilize a Limited Subgrade Frost Penetration.
G. Final design summary on FAA Form 5100-1
Pavement thicknesses based upon aircraft loading were calculated utilizing the current FAA computer program for rigid pavement (FAARFIELD). The FAA 5100-1 form included in this report was designed to be used with the previous pavement design methodology which utilized design aircraft, respective design curves, and equivalent departures. Detailed pavement design information can be found in Appendix E of this report.
H. Conclusion
The recommended pavement section was computed by FAARFIELD and consists of 6 inches of Portland Cement Concrete Pavement (P-501) on 6 inches of Crushed Aggregate Base Course (P-209) on 9 inches of Fly Ash Treated Subgrade (P-158) compacted to a Standard Proctor (ASTM D 698) density.
This recommendation considers the sponsor certification criteria that requires all FAA funded AIP projects to follow the guidelines presented in the current versions of the FAA Advisory Circulars.

2.0 SITE AND PROJECT DESCRIPTIONS
The following project understanding is based on discussions with Jviation and a site
reconnaissance by a geotechnical engineer from TSi. The project consists of improvements at
the Northwest Missouri Regional Airport at Maryville, Missouri. The general location of the
project site is shown below. The Site and Boring Location Plan, Figure 1 in Appendix A,
provides a more detailed plan of the project area.
The Northwest Missouri Regional Airport is in the early stages of design for the reconstruction
of Runway 14-32 and an apron rehabilitation. The proposed project includes reconstructing the
north 4,000 feet of Runway 14-32 and rehabilitating the east half of the apron.

3.0 FIELD EXPLORATION AND LABORATORY TESTING 3.1 FIELD EXPLORATION On November 19, 2014, TSi conducted an exploration program at the project site consisting of eight borings, designated as Borings B-1 through -8. Six of the borings were along the existing runway and two were in the apron. The pavement at each boring location was cored and photographed. The pavement core photographs from this exploration are included in Appendix C. The approximate locations of the cores are indicated on the Site and Boring Location Plan, Figure 1 in Appendix A. The pavement cores were drilled using a pavement core machine with a 6-inch diameter pavement core barrel and a CME-45 truck-mounted drill rig to advance flight auger drilling tools. Three standard penetration test (ASTM D 1586) samples and one Shelby tube (ASTM D 1587) sample were obtained at each boring. Auger cuttings were collected from the top 5 feet of the borings and combined to form three composite samples for modified Proctor moisture density relationship and California Bearing Ratio tests (CBR). One composite sample was collected for the apron (B-07 and -08), one for the north section of the runway (B-04, -05 and -06) and one for the south section of the runway (B-01, -02 and -03). The results of the field tests and measurements were recorded on field logs and appropriate data sheets by TSi’s engineer. Those data sheets and logs contain information concerning the exploration methods, samples attempted and recovered, indications of the presence of various subsurface materials, and the observation of groundwater. The field logs and data sheets contain the engineer’s interpretations of the conditions between samples, based on the performance of the exploration equipment and the cuttings brought to the surface. The final data included in this report were based on the field logs, modified as appropriate based on the results of laboratory testing of soil samples.
3.2 LABORATORY TESTING A laboratory testing program was conducted by TSi to determine selected engineering properties of the obtained soil samples. The following laboratory tests were performed on the samples recovered from the borings:
visual descriptions by color and texture of each sample (ASTM 2488);
natural moisture content of fine-grained samples (ASTM D 2216);
Atterberg limits on selected cohesive samples (ASTM D 4318);
grain size analysis of granular soils (ASTM D422); and
California Bearing Ratio (CBR) (ASTM D 6951). The results of the laboratory tests are summarized on the boring logs. The analyses and conclusions contained in this report are based on field and laboratory test results and on the interpretations of the subsurface conditions as reported on the logs. Only data pertinent to the objectives of this report have been included on the logs; therefore, these logs should not be used for other purposes.

4.0 SUBSURFACE CONDITIONS
Details of the subsurface conditions encountered at the core locations and their pertinent
engineering characteristics are described in the following paragraphs. Conditions represented by
the cores should be considered applicable only at these locations on the dates shown; the
reported conditions may be different at other locations or at other times.
4.1 GENERALIZED SUBSURFACE PROFILE
The borings and pavement cores generally encountered approximately 6 inches of Portland
cement concrete (PCC) pavement along the runway underlain by about 6 inches of base rock.
Exceptions to this were B-03 which encountered about 16 inches of base rock and B-06 which
encountered a thin layer of asphaltic concrete (AC) beneath 7 inches of PCC. The apron area
consisted of approximately 6 inches of PCC with no base rock encountered. Table 1 below lists
the pavement type and thicknesses encountered at each boring and pavement core:
TABLE 1.
PAVEMENT MATERIALS THICKNESS
Boring Concrete (in) Asphalt (in) Base Rock (in) Location
B-01 6.0 NE 6.0 Runway
B-02 6.0 NE 6.0 Runway
B-03 5.5 NE 16.0 Runway
B-04 5.75 NE 6.0 Runway
B-05 6.0 NE 6.0 Runway
B-06 7.0 1.75 6.0 Runway
B-07 5.5 NE NE Apron
B-08 6.0 NE NE Apron NE = Not Encountered
Underlying the pavement materials at most of the borings is a gray-brown fat clay (CH, in
accordance with the Unified Soil Classification System) with varying amounts of sand.
Moisture content tests of the fat clay range from 4% to 29% with an average of 23%. Atterberg
limits tests on samples of the clay resulted in liquid limits that range from 48 to 73 (average 62)
and with plasticity indices that range from 29 to 50 (average 41). Dry unit weights of the clay
range from 93 to 100 pounds per cubic feet (pcf) with an average of 94 pcf. Undrained shear
strengths of the clay range from 0.63 to 3.25 tons per square feet (tsf) with an average of 1.23 tsf.
4.2 GROUNDWATER
Groundwater was not encountered beneath the pavement during this investigation. The presence
or absence of groundwater at a particular location does not necessarily mean that groundwater
will be present or absent at that location at other times. Seasonal variations and other unknown
considerations could cause fluctuations in water levels and the presence of water in the soils.
5
5.0 ENGINEERING ASSESSMENTS AND RECOMMENDATIONS
5.1 SWELLING CLAY CONSIDERATIONS
Laboratory tests indicated that the on-site soils are high plasticity clays with high shrink/swell
potential. High plasticity fat clays will be exposed during grading. Fat clays are of concern with
regard to their potential for volume change. These materials swell when they absorb water and
shrink when they dry out. This concern applies to these materials whether they are in their
natural condition or used as fill material. Potential detrimental effects for development of the
site include heaving, settlement, and differential movements of pavements constructed directly
over these materials.
It is recommended that where high plasticity clays (CH) are found at the subgrade levels of the
proposed pavement, they should be overexcavated to a depth of 18 inches below the subgrade
level. These materials should be replaced with Low Volume Change (LVC) fill material, as
discussed in Section 6.4 of this report. If the on-site soils are treated with lime, the modified clay
will meet the requirements of an LVC fill material. The optimum lime percentage was not part
of this scope of work and will need to be determined in the laboratory before construction
activities begin.
In addition to the removal and replacement or treatment, some relatively simple design and
construction considerations are recommended that will help to maintain the natural moisture
contents of the clays. Avoiding conditions that could result in excessive wetting or drying of
these materials will reduce their potential for volume change. The following design and
construction precautions are recommended:
1. Positive surface drainage should be provided during and after construction to prevent the
ponding of water on, or adjacent to, pavements.
2. Stormwater runoff should be collected and carried away from the pavements to avoid
saturating the subgrade under the pavements.
3. Excessive watering of grass adjacent to the pavements should be avoided.
These considerations should be incorporated into the site grading and development plans for the
project. In addition, individual structures/pavement areas should be observed during
construction to determine the specific soil conditions that exist at that location and the most
prudent approach for mitigating any swelling soil concerns.
5.2 PAVEMENT DESIGN
The fat clay encountered at the borings is not appropriate for support of the pavement section and
allows very little drainage. The native clay soils at the site will require lime treatment to be
acceptable for pavement support. The pavement section should also be directly underlain by a
crushed limestone layer, such as MoDOT Type 5, (minimum 6 inches) to allow drainage. The
lime-treated soils and crushed limestone may be counted in the LVC fill requirement in Section
5.1.
6
Lime-modified Proctor and CBR testing was not included in the scope of this work. Based upon
previous experience, the lime application will need to be applied at a rate of 3% to 5% of the
treated soil on a dry unit weight basis. The exact amount of lime application should be
determined in the laboratory before construction begins. The soil should be treated and
compacted in lifts with a maximum thickness of 9.0 inches to help mixing of the soil and lime.
The CBR value for lime-treated soils will be greater than the CBR values measured in the native
clay. The stabilized soil should be compacted as recommended in Section 6.5 of this report.
Suggested specifications for the lime treatment can be provided if desired.
Three CBR tests of the native fat clay were performed, one on a combined sample from B-01,
-02 and -03, one on a combined sample from B-04, -05 and -06, and one on a combined sample
from B-07 and -08. Table 2 below lists the results of the CBR tests and the modified Proctor test
results.
TABLE 2
CBR AND MODIFIED PROCTOR TEST RESULTS
Sample Location Maximum Dry

B-01, -02, -03 121.0 12.2 3.0
B-04, -05, -06 117.6 14.8 3.0
B-07, -08 117.5 13.4 3.0
Based on the general character of the on-site subsurface conditions and assuming a properly
prepared subgrade, the measured CBR value of 3 is considered appropriate for use in designing
the flexible pavement sections for the site. A resilient modulus value can be estimated by using
the CBR value of 3 with the following equation, as taken from the AASHTO design guide:
Resilient modulus = 2555 (CBR)0.64
Rigid pavement design can be based on a modulus-of-subgrade reaction (k) of 100 pounds per
cubic inch (pci) for the subgrade. These values for rigid and flexible pavement design are based
on the requirement that the pavement subgrade is prepared in accordance with the
recommendations provided in this report.

6.0 SITE PREPARATION AND EXCAVATION CONSIDERATIONS
6.1 SUBGRADE PREPARATION
Construction areas should be stripped of vegetation, root mass, organic soil, fill material,
pavement and any deleterious materials prior to site excavation and grading. Care should be
taken during stripping to prevent excessive disturbance of the underlying soil. After the removal
of these materials, and where further excavation is not required, the exposed subgrade should be
proofrolled. Proofrolling is accomplished by passing over the subgrade with proper equipment
such as a loaded tandem-axle dump truck or scraper, and observing the subgrade for pockets of
excessively soft, wet, disturbed, or otherwise unsuitable soils. Any unacceptable materials thus
found should be excavated and either recompacted or replaced with new structural fill.
Prior to placing fill in any area, the subgrade should be scarified to a depth of about 6 inches, the
moisture content adjusted to near its optimum moisture content, and the subgrade recompacted in
accordance with recommendations made in subsequent sections of this report. The
recommended proofrolling and/or scarification and recompaction may be waived if, in the
opinion of a geotechnical engineer, this procedure would be detrimental or unnecessary.
Following the satisfactory preparation of the subgrade, controlled fill material may be placed.
6.2 EXCAVATIONS
The existing fill and clay soils on the site can be excavated using conventional earth moving
equipment and methods. Trenching, excavating, and bracing should be performed in accordance
with OSHA (Occupational Safety and Health Administration) regulations and other applicable
regulatory agencies. In accordance with the OSHA excavation standards, the existing fat clay fill
soils at the site are considered Type C, which requires a side slope for excavations of not steeper
than 1.5 horizontal to 1.0 vertical (1.5H:1.0V). However, worker safety and classification of the
excavation soil is the responsibility of the contractor. Also according to OSHA requirements,
any excavation extending to a depth of more than 20 feet must be designed by a registered
professional engineer.
6.3 SUBGRADE PROTECTION
Construction areas should be properly drained in order to reduce or prevent surface runoff from
collecting on the exposed subgrade in excavations. Any ponded water on the exposed subgrade
should be removed immediately. Temporary stormwater swales and collection areas may be
required to control surface water flow into low areas of the site or into trench excavations.
Excavations should be kept dry and foot traffic on the bearing surface should be kept to a
minimum. Any disturbed, loose, or soft material that is encountered or develops in the
excavations should be removed.
8
6.4 FILL AND BACKFILL MATERIALS
Engineered fill should consist of approved soils or crushed limestone material, free of organic
matter and debris. Fill material placed within 18 inches of the pavement subgrade should consist
of select LVC material. The LVC fill should consist of approved, well-graded granular materials
or low to moderate plasticity cohesive soil. Low to moderate plasticity cohesive materials used
as LVC fill should consist of inorganic clay with a liquid limit less than 50 and a plasticity index
of less than 25. Granular fill should have a maximum particle size of 1.5 inches. The natural fat
clay soils present on this site cannot be used for LVC fill unless modified with lime treatment.
Some of the soil on the site will require the addition of moisture prior to compaction. This
should be performed in a controlled manner, and the moistened soil should be thoroughly
blended to produce a uniform moisture content. Fat clays and shale should be compacted wet of
their optimum moisture content. If fill is placed during the winter season, fill materials should be
carefully observed to see that no ice or frozen soils are placed as fill or remain in the base
materials upon which fill is placed.
Some of the on-site soil may require moisture reduction prior to compaction. During warm
weather, moisture reduction can generally be accomplished by disking, or otherwise aerating the
soil. When air-drying is not possible, a moisture-reducing chemical additive, such as lime or
Class C fly ash, could be used as a drying agent.
6.5 FILL AND BACKFILL PLACEMENT
Cohesive fill should be compacted to a dry density of at least 95% of the modified Proctor
maximum dry density (ASTM D 1557) of the soil. Granular material, such as crushed limestone,
should be compacted to at least 100% of the modified Proctor maximum dry density. The
moisture content of lean clay at the time of compaction should generally be within ±3% of the
optimum moisture content of the material as determined by the standard Proctor compaction test.
Fat clay material should be placed and maintained at a moisture content ranging from 0 to 4%
wet of the optimum. Fill should be placed in loose lifts not in excess of 8 inches thick, and
compacted to the aforementioned criterion. However, it may be necessary to place fill in thinner
lifts to achieve the recommended compaction when using small hand-operated equipment.
6.6 GROUNDWATER CONSIDERATIONS
No groundwater was encountered while drilling in any of the borings. The presence or absence
of groundwater at a particular location does not necessarily indicate that groundwater will be
present or absent at that location at other times. Seasonal variations and other unknown
considerations could cause fluctuations in water levels and the presence of water in the soils.
9
7.0 CONSTRUCTION OBSERVATION AND TESTING
It is recommended that TSi be retained during construction to perform testing and observation
services for the following items:
removal of existing pavements and any deleterious materials;
proofrolling, recompaction, and preparation of the pavement subgrade;
placement and compaction of fill and backfill; and
quality assurance testing for concrete and pavement materials.
These quality assurance services should help to verify the design assumptions and maintain
construction procedures in accordance with the project plans, specifications, and good
engineering practice.

GENERAL NOTES The number of borings is based on: topographic and geologic factors; the magnitude of structure loading; the size, shape, and value of the structure; consequences of failure; and other factors. The type and sequence of sampling are selected to reduce the possibility of undiscovered anomalies and maintain drilling efficiency. Attempts are made to detect and/or identify occurrences during drilling and sampling such as the presence of water, boulders, gas, zones of lost circulation, relative ease or resistance to drilling progress, unusual sample recovery, variation in resistance to driving split-spoon samplers, unusual odors, etc. However, lack of notation regarding these occurrences does not preclude their presence. Although attempts are made to obtain stabilized groundwater levels, the levels shown on the Logs of Boring may not have stabilized, particularly in more impermeable cohesive soils. Consequently, the indicated groundwater levels may not represent present or future levels. Groundwater levels may vary significantly over time due to the effects of precipitation, infiltration, or other factors not evident at the time indicated. Unless otherwise noted, soil classifications indicated on the Logs of Boring are based on visual observations and are not the result of classification tests. Although visual classifications are performed by experienced technicians or engineers, classifications so made may not be conclusive. Generally, variations in texture less than one foot in thickness are described as layers within a stratum, while thicker zones are logged as individual strata. However, minor anomalies and changes of questionable lateral extent may appear only in the verbal description. The lines indicating changes in strata on the Logs of Borings are approximate boundaries only, as the actual material change may be between samples or may be a gradual transition. Samples chosen for laboratory testing are selected in such a manner as to measure selected physical characteristics of each material encountered. However, as samples are recovered only intermittently and not all samples undergo a complete series of tests, the results of such tests may not conclusively represent the characteristics of all subsurface materials present.

PENETRATION – BLOWS Number of impacts of a 140-pound hammer falling a distance of 30 inches to cause a standard split-barrel sampler, 1 3/8 inches I.D., to penetrate a distance of 6 inches. The number of impacts for the first 6 inches of penetration is known as the seating drive. The sum of the impacts for the last 12 inches of penetration is the Standard Penetration Test Resistance or “N” value, blows per foot. For example, if blows = 6-8-9, “N” = 8+9 or 17.
OTHER NOTATIONS Recovery % – length of recovered soil divided by length of sample attempted. 50/2” Impacts of hammer to cause sampler to penetrate the indicated number of inches WR Sampler penetrated under the static loading of the weight of the drill rods WH Sampler penetrated under the static loading the weight of the hammer and drill rods HSA Hollow stem auger drilling method FA Flight auger drilling method RW Rotary wash drilling methods with drilling mud AH Automatic hammer used for Standard Penetration Test sample SH Safety hammer with rope and cathead used for Standard Penetration Test sample

1. COORDINATION During construction, airport operational safety is of paramount importance. Coordination of project information to all individuals involved with the project is essential for ensuring safe operations are maintained at all times. In order to minimize potential for incidents during construction, it is imperative that all individuals involved with the project and/or airport users be kept informed of any and all changes to operations. Discussions of operational safety will need to take place throughout the entire life of the project, including design, bidding, pre-construction, and construction. Meetings between the Resident Engineer, Northwest Missouri Regional Airport, Contractor, sub-contractors, airport tenants and airport users will be required to discuss specific project related impacts to operations. The Airport staff is ultimately responsible for the safety at the airport. Notice to users of operational changes due to construction will be issued via NOTAMs by the airport. No closures will be permitted without the pertinent NOTAM in place for each specific closure. Emergency access for off-airport (Police, Fire, and EMT) based emergency service shall be maintained at all times. Routing for such traffic shall be determined and made known to all supervisor personnel involved in the construction project. Coordination of this access will be proposed by the Contractor and approved by the Resident Engineer and the Airport/City. A pre-construction meeting will be held after the project has been awarded and prior to the Contractor beginning work or staging major construction material and equipment on-site. The Airport/City, the Contractor’s on-site supervisory staff, and representatives from the Engineer shall be present. Safety and this document will be a significant topic on the agenda. Operational safety during construction will be a main topic of discussion at the pre-construction meeting. A. CONTRACTOR PROGRESS MEETINGS
The Contractor shall be required to adhere to this CSPP throughout the project duration. The Contractor is required to have weekly construction progress meetings to discuss all relevant construction topics including safety reminders, scheduling, and general construction issues. Attendance of the Contractor, Resident Engineer, Airport/City, and any other pertinent personnel are required at these meetings. Operational safety will be a standing agenda item for discussion during these progress meetings. A review of the Contractor’s adherence to the project’s Construction Safety and Phasing Plan (CSPP) and Safety Plan Compliance Document (SPCD) will be made at each meeting. Immediate correction of any deficiencies or violations will be required. The location and time of the weekly meetings will be determined during the pre-construction meeting. Where operational safety is concerned, the Contractor shall update the Resident Engineer overseeing construction on daily basis or more frequently if needed, of any changes or Contractor concerns.
B. SCOPE OR SCHEDULE CHANGES
In the event of a scope or schedule change, the Contractor shall notify the Resident Engineer and the Northwest Missouri Regional Airport/City immediately. All parties involved will need to evaluate the impact(s) of the change and will determine what measures will need to be taken to maintain a safe construction site. Change in the scope or duration of the project may necessitate revisions to the Construction Safety and Phase Plan (CSPP). No scope changes shall occur without approval of the MoDOT and FAA.
Northwest Missouri Regional Airport 2 MoDOT Project No. 16-002A-1 Construction Safety and Phasing Plan February 10, 2017
C. FAA ATO COORDINATION
The FAA ATO will need to be notified immediately of any changes that affect aircraft movement within the airport which include airway facility shutdowns and restarts. The Airport/City will be responsible for coordinating any changes including NOTAMs to the FAA ATO. The NAVAIDs at the Northwest Missouri Regional Airport are not FAA-owned, but are owned by the City of Maryville.
2. PHASING
In order to minimize disruptions to airport operations during construction, construction will be broken up by areas to limit the amount of aircraft operational areas affected at any given time. Maintaining continual access to the terminal building is mandatory during all phases of construction. The phasing plan proposed was developed with help from the Airport and is considered to be the most effective way of maintaining the required aircraft access, while imposing the least amount of impact on construction operations, and without sacrificing safety. The phasing for this project is presented below, and is visually depicted in the Construction Safety Drawings (Sheets G007 through G010) attached at the back of this document. This project will be completed in two separate schedules with each schedule having one phase. Each of the phases is discussed in further detail in the Construction Safety Drawing plan sheets included at the end of this document. A. PHASE ELEMENTS
I. Schedule I, Phase 1 – Apron Reconstruction
(Construction Safety Drawing G009) During this phase, the Contractor will be removing the existing concrete pavement section (per P-101 Surface Preparation), preparing subgrade (per P-152 Excavation, Subgrade, and Embankment and P-158 Fly Ash Treated Subgrade), installing improvements to the drainage system (per D-705 Pipe Underdrains for Airports), and constructing a new concrete pavement section (per P-501 Portland Cement Concrete Pavement). Hauling activities will be required to follow routes indicated in the attached Construction Safety Drawings. Although not anticipated, aircraft will have the right of way at all times. Prior to beginning work on this phase, the Contractor shall have barricades in place in accordance with the plans.
Access for traffic to the terminal and fuel farm during this phase will be via the southwest apron. Aircraft parking can be achieved on the southwest apron during this project. Ground service equipment access to the runway and southwest apron will be via the project haul route to Taxiway A, as depicted on the Construction Safety Drawings. Phase 1 is to be constructed concurrently with Phase 2. The duration of Schedule I will be 75 calendar days. While concurrent with Schedule II, the airport shall remain closed.
Northwest Missouri Regional Airport 3 MoDOT Project No. 16-002A-1 Construction Safety and Phasing Plan February 10, 2017

The location and design of any signs will be directed by the Engineer or Airport/City and provided by the Contractor.
16. HAZARD MARKINGS AND LIGHTINGS
A. PURPOSE
The hazard marking and lighting prevents pilots from entering areas closed to aircraft, and prevents construction personnel from entering areas open to aircraft. Prior to construction on or adjacent to any taxiway or apron, the Contractor shall, upon approval by the Engineer, close the taxiway and/or apron, in accordance with the specific phasing plan associated with that phase, prior to beginning work. The Contractor shall be responsible for clearly marking and defining the closed area(s) by use of warning lights, barricades, flags and closed taxiway markings in conformance with Advisory Circular 150/5370-2F. Approved hazard marking and lighting barricades must also be used by the Contractor to identify any open manholes, small areas under repair, stockpiled material, waste areas, and areas subject to jet blast. The Contractor shall be responsible for maintaining these barricades and keeping them clearly visible at all times. Specific marking and lighting equipment details, location and other pertinent information regarding hazard marking materials including low-profile barricades are shown on the Construction Safety Drawings, attached to the back of this document. Please note that each
Northwest Missouri Regional Airport 12 MoDOT Project No. 16-002A-1 Construction Safety and Phasing Plan February 10, 2017
phase may have unique details. Additionally, prior to any deviations in location or type of hazard marking materials shall be coordinated with the Engineer and Airport/City.
B. EQUIPMENT
Approved low-profile barricades are to identify and define the limits of construction and hazardous areas on airports. Physical requirements and spacing of the barricades are specified in the construction drawings for this project. The barricades must be weighted down per the manufacturer’s recommendations to prevent the barricades from moving due to wind or jet blast. The spacing must be such that a breach is physically prevented barring a deliberate act. For example, if barricades are intended to exclude vehicles, gaps between barricades must be smaller than the width of the excluded vehicles, generally four feet. Provision must be made for emergency access. If barricades are intended to exclude pedestrians, they must be continuously linked. Continuous linking may be accomplished through the use of ropes, securely attached to prevent FOD. The flashing lights on the approved barricades must meet the luminance requirement of the State Highway Department. The flashing lights must be red or an approved equal. Lights must be mounted on barricades and spaced at no more than ten feet. Lights must be operated between sunset and sunrise and during periods of low visibility whenever the airport is open for operations. They may be operated by photocell, but this may require that the Contractor turn them on manually during periods of low visibility during daytime hours.
17. PROTECTION OF RUNWAY AND TAXIWAY AREAS
A. RUNWAY SAFETY AREA (RSA)
The Northwest Missouri Regional Airport defines the RSA for Runway 14/32 as the area that is within 75 feet from the centerline of the runway. Construction operations shall be permitted in the RSA when the runway is closed by NOTAM.
