Driskell Park Construction Project Manual - City of Albany, Georgia
This project manual contains construction documents and specifications for the Driskell Park renovation project located at 1021 South McKinley Street in Albany, Georgia, prepared by the City of Albany Parks and Recreation Department. The scope of work includes construction of a new community center, two pavilions, tennis courts, a football field, underground stormwater storage, and a retention pond. Sealed bids were due October 21, 2022, at 2:30 PM, submitted to the City of Albany Procurement Division. The project is designated as Bid No. 23-007 with LOSE Project #20091-1. The general contractor must have completed a minimum of three projects of similar size and complexity within the past five years and must submit project reference forms with their bid. The contract includes two alternates: Alternate #1 for Structure B Pavilion (30'x30') and Alternate #2 for Multi-Purpose Synthetic Turf Field, both submitted as lump sum bids. Work must begin within 10 calendar days after issuance of the Notice to Proceed. The project site is an active City facility requiring coordination with existing park users; the contractor must maintain security fencing and ensure public safety throughout construction.
The general contractor bears responsibility for all project costs including fees, utilities during construction, erosion and sedimentation control, NPDES permit compliance, and subdrainage connections. The contractor assumes all costs associated with temporary and permanent utility service connections and must transfer utility accounts to the City upon project completion. Geotechnical investigation indicates Coastal Plain soils with zones of low-consistency materials that may require undercutting and stabilization; the contractor must conduct proofrolling and subgrade preparation in accordance with engineering recommendations. The contract documents specify Select Soil Fill compaction to 98 percent of Standard Proctor maximum density and require TTL (the geotechnical engineer) to provide full-time observation during fill operations and construction. The City requires the contractor to secure all necessary permits and coordinate with permit officials and emergency services for any temporary facility closures. Pre-engineered structures, playground equipment surfacing, sports lighting systems, and mural installation will be procured by the City through separate third-party contractors, requiring general contractor coordination for scheduling, access, and utility connections.

EXECUTIVE SUMMARY
This Geotechnical Report has been prepared for use by The City of Albany Engineering Department for a planned Project referred to hereinafter as Driskell Park or the Project. The Project site is located at the existing Mary Young Cummings Memorial Park at 1008 South McKinley Street just south of the existing family Literacy Connection facility in Albany, Georgia.
Based on provided project information, we understand the project will consist of constructing a new community center, two pavilions, tennis courts, football field, underground stormwater storage, and a retention pond.
The site predominantly consisted of Coastal Plain soils typical of the local area. The soils include materials described as silty sand, clayey sand, silty-clayey sand, and poorly graded sand with clay (SM, SC, SC-SM, and SP-SC).
Zones of low consistency soils (N values ≤ 9 bpf) were encountered in the majority of the boring locations at depths ranging from 1 to 5 feet below ground surface (bgs). A zone of low consistency soils was deeper in boring B-03 extending to 15 feet bgs. These low consistency soils could be subject to unacceptable displacement and rutting during mass grading operations. We anticipate that plowing and drying (processing) of low consistency soils during a warm and dry period, may help reduce the amount of undercutting needed. Removal of existing underground foundations, slabs, underground utilities, etc. from the construction areas should be anticipated. Care should be taken to properly backfill voids remaining from the removal of existing site features, if any are present in the construction areas
Provided the site is prepared according to the recommendations presented in this report, the proposed buildings can be supported on typical shallow spread foundations bearing on stable in-situ soils or properly compacted fill. Spread foundations can be sized using an allowable net bearing pressure of 2,000 pounds per square foot (psf).
This summary is provided for convenience only. For those individuals and entities that may need more details or technical information from this report for their use, it must be read in its entirety to understand fully the information and recommendations provided for the Project.

2.2 USDA Soil Survey
Based on the Natural Resource Conservation Service (NRCS) soil survey for Dougherty County, Georgia, the near surface soils of this site are composed primarily of Red Bay loamy sand soils (RgB2). The published water table upper limits for the Red Bay soils are more than 80 inches below the top of ground surface and has a published natural drainage class of well drained.
2.3 Site Geology
The subject site in Albany, Georgia is situated within the Coastal Plain physiographic province.
The site is initially underlain by alluvium and undifferentiated terrace deposits from the Quaternary geologic age. This strata transitions to Ocala limestone from the Eocene geologic age. The Ocala Limestone of late Eocene age overlies the Lisbon Formation and occurs at from about 70 to 350 feet below land surface. It is a cream to brown, rather pure limestone. The Coastal Plain region in this part of Georgia is comprised of sands, gravels, and clay.
2.4 Subsurface Stratigraphy
Subsurface conditions within the project limits were evaluated by completed drilling operations at eight (8) test boring locations as shown on the Boring Location Plan in Appendix A. The borings were drilled to depths ranging from 10 to 20 feet bgs.
Generally, the soil profile included Coastal Plain soils composed of silty sand, clayey sand, silty, clayey sand, and poorly graded sand with clay (SM, SC, SC-SM, and SP-SC). Generalized information from the soil borings is summarized below.

Additional information about the subsurface stratigraphy encountered at the exploratory boring locations is provided on Test Boring logs in Appendix A.
The Test Boring Logs presented in Appendix A represent our interpretation of the subsurface conditions based on tests and observations performed during the drilling operations at the test boring locations, visual examination of the soil samples by a geotechnical engineer, and laboratory tests conducted on the retrieved soil samples. The USCS classifications enclosed in parenthesis indicate a visual classification. The lines designating the interfaces between various strata on the Test Boring Logs represent the approximate strata boundaries, however, the transition between strata may be more gradual than shown, especially where indicated by a broken line. All data should only be considered accurate at the exact test boring location.
2.5 Groundwater Conditions
Subsurface groundwater was not encountered at the time of our drilling procedures. Subsurface groundwater is generally encountered as a continuous water surface that is generally present year-round or as a discontinuous “perched” or temporary water surface. Both groundwater surfaces can be influenced by changes in season, climate, precipitation, vegetation, surface runoff, water levels in nearby water bodies, and other factors. The groundwater level below the site may fluctuate up or down in response to such changes and may be at different levels than indicated on the soil boring logs at times after the exploration. Sometimes shallow temporary subsurface water conditions can develop as a result of above-normal rates of precipitation or surface runoff that exceeded the rate at which infiltration can pass through the subsurface strata.
These temporary water levels are called “perched” or “trapped” water levels, and they can change rapidly over short horizontal distances and short durations of time. It is often not possible to distinguish between a temporary perched water level and the groundwater table based on one-time observations of water levels in open boreholes.
2.6 Hydraulic Conductivity Testing
Field tests were performed in hand auger borings at locations HA-01 (football field), HA-02 (underground stormwater storage), and HA-03 (detention pond) to estimate in-situ saturated

Tests were performed at depths of 46 inches bgs and 10 feet bgs, respectively, utilizing a Compact Constant Head Permeameter (Amoozemeter) manufactured by Ksat, Inc. The following table presents the Ksat values determined in the field.

3.0 GEOTECHNICAL CONSIDERATIONS
The following geotechnical consideration have been prepared based on the data collected or developed during this Project and, our experience with similar projects, and our knowledge of sites with similar surface and subsurface conditions.
3.1 Loose Soils
Zones of low consistency soils (N values ≤ 9 bpf) were encountered in the majority of the boring locations at depths ranging from 1 to 5 feet below ground surface (bgs). A zone of low consistency soils was deeper in boring B-03 extending to 15 feet bgs. These low consistency soils could be subject to unacceptable displacement and rutting during mass grading operations, especially during seasonal wet weather conditions. We anticipate that plowing and drying (processing) of existing subgrades, during a warm and dry period, may reduce the amount of undercutting needed.
4.0 EARTHWORK RECOMMENDATIONS
4.1 Subgrade Preparation and Stabilization
Site preparation should initially include removal of organic laden topsoil and existing site features (i.e. underground utilities, concrete sidewalks, etc.) from the construction areas. In general, the construction areas to be cleared should extend at least 5 feet beyond the building footprints.
Following site clearing and stripping, the disturbed subgrade soils in fill or at-grade areas should be evaluated by proofrolling, which consists of systematically traversing the site with overlapping passes of a loaded tandem-axle dump truck at a walking pace. Proofrolling should be performed in the presence of a TTL representative who should mark and document areas which pump or rut excessively. Unstable subgrades should be undercut and backfilled or reworked (scarified and
TTL Project No. 000210603696.00 Page 9 of 14
© 2022, TTL, Inc. Purpose | Passion | Principles recompacted) in-place. We recommend the contract documents establish a unit cost for undercutting and replacing wet or unsuitable soils (per cubic yard in-place).
If construction is performed during seasonal wet weather conditions, areas of rutting or pumping may be more widespread. Additional undercutting can often be required during site grading operations if the work is attempted during, or just after, periods of significant rainfall. Performing site work during seasonal dry weather conditions with wide track-mounted low ground pressure equipment often reduces subgrade undercutting requirements. Traversing wet subgrade soils with heavy rubber-tired equipment often results in subgrade disturbance and the need for subsequent processing/compaction and/or undercutting.
4.2 Compacted Fill
Compacted fill is new fill material placed as backfill in undercut excavations and utility excavations, or placed during mass grading to raise final site grades above existing site grades below pavements and structures. Fill that is placed outside of current or proposed development areas is sometimes called “common fill” or “general fill”. Materials that do not meet compacted fill requirements may sometimes be used in these “common” or “general” fill areas. In addition, materials that meet requirements for compacted fill may also be used in these areas. Soils with debris, garbage, organic strippings, and other deleterious materials (which can decay, rot, or corrode over time) should not be used as fill in any site areas.
Criteria for fill characteristics, compaction procedures, and compaction control are listed in the table below. The near surface on-site SC, SM and SC-SM soils typically meet the criteria for Select Soil Fill below. Fill operations should not begin until representative soil samples are collected from cut areas and proposed off-site borrow sources and tested for plasticity and moisture/density relationship (allow 3 to 4 days for sampling and testing soil). The test results will be used to determine whether or not the proposed borrow material meets project specifications.
Fill placement and compaction should be observed by our representative on a full-time basis.

Designation as a SC-SM, SM, or SC, in accordance with the Unified Soil Classification System (USCS).
1For preliminary planning only. Our technician/engineer should determine the actual test frequency.
2 In addition, the fill must be stable under the influence of compaction equipment. Heavy construction traffic should not be allowed to travel on compacted fill areas, except on designated haul roads, to reduce the potential for damaging a previously compacted fill subgrade
If grading occurs during seasonal wet weather conditions, when drying soils is more difficult and time-consuming, the grading contractor may have difficulty achieving suitable moisture conditions for proper compaction of Select Soil Fill. The contractor should be prepared to provide the means and methods to dry soils to provide the required compaction.
If site preparation operations are not continuous from start to finish or a long period of inclement weather interrupts site preparation, the surface receiving fill should be scarified to a depth of 6 inches and re-compacted as recommended in the following paragraph before placement of the fill is started. No material should be placed on surfaces that are muddy, frozen or that contain frost.
It is anticipated that compaction may be accomplished by steel-wheeled rollers. Other equipment suited to the soil being compacted may be necessary depending on off-site fill, if any, selected.
Materials should be moisture conditioned, as necessary, to provide a moisture content that will facilitate obtaining the recommended compaction.
TTL’s soils engineering technician should witness the filling operations and perform in-place density tests to confirm the specified fill compaction is achieved. Areas that fail to achieve the recommended compaction criteria should be reworked and retested prior to proceeding with subsequent phases of construction. Furthermore, select undercut and backfill areas should be tested, although this may contain smaller quantities of fill than specified.
4.3 Drainage Considerations
The performance of a grade-supported slab and foundation systems will not only be dependent upon the quality of construction, but also upon the stability of the moisture content of the underlying soils.
We recommend that site drainage be developed so ponding of surface runoff near the proposed structures and equipment does not occur during or after construction. Further, it will be important for the contractor to maintain the site in a positively drained condition during construction. Ponding of water near structure foundations may cause significant moisture variations in the soils adjacent to the foundation, thus decreasing their stability. Saturation of foundation/slab supporting soils can lead to destress to the structure foundation, floor slab, framing, and cosmetic finishes. Project specifications should clearly detail the contractor’s responsibility to notify the designers and the geotechnical engineer if conditions are encountered in the field that would require remedial treatment or which could affect the integrity of the site or the proposed structures.
TTL Project No. 000210603696.00 Page 11 of 14

When establishing the final grade around the structure, we recommend the following be considered:
• Elevation of the ground surface adjacent to shallow perimeter foundations should be at least 6 inches below the finished floor elevation.
• The slope of the ground surface away from the structure should be a minimum of 5 percent for a distance of at least 10 feet, where possible.
• Gutters should be considered to control roof runoff. Gutter downspouts should extend at least 3 feet from the face of the structure or tie into a stormwater buried drainage system.
