Addendum No. 1

CITY OF FOREST PARK, GEORGIA

STARR PARK - PHASE I

PROJECT NO.: 02072023

ADDENDUM NO. 1

MARCH 16, 2023

ALL BIDDERS FOR THE REFERENCED PROJECT ARE REQUIRED TO MAKE THE CHANGES BELOW TO THE

EXISTING CONTRACT DOCUMENTS OBTAINED FROM THE CITY OF FOREST PARK’S WEBSITE FOR BIDDING

PURPOSES:

ITEM NO. 1: RESPONSE TO WRITTEN QUESTIONS RECEIVED PRIOR TO THE FEBRUARY 28, 2023 AT 12:00

PM NOON DEADLINE ESTABLISHED IN THE CONTRACT DOCUMENTS:

• QUESTION:

o What is the estimated cost or budget?

• RESPONSE:

o Project budgets and estimates are proprietary.

• QUESTION:

o Can I get a copy of any addendum released to date?

o All project and bid related documents are posted on the City’s website.

o Is irrigation required for this project? If so, where are the irrigation plans? Or is this a design-build irrigation proposal?

• RESPONSE:

o Per L1.00, irrigation is required for this project. Irrigation design shall be design/build by the contractor and included in base bid.

o When is the estimated installation date?

• RESPONSE:

o Construction is expected to begin within 30 days after the contacts have been completely executed.

o Is there a General Contractors license requirement?

o Yes, per the Contract Documents.

o Can you provide a CAD file?

o CAD files will be provided only to the successful bidder that is awarded the contract.

o Is this a classified or unclassified bid? There is no units for unsuitable.

• RESPONSE:

o This is an unclassified bid. However, bidding contractors may reference Geotechnical

Investigation report prepared by Atlas Technical Consultants, dated May 6, 2022.

o Can this site be balanced to avoid export/import of dirt?

• RESPONSE:

o Earthwork calculations and takeoffs are ultimately the responsibility of the contractor.

Costs for any necessary haul-in or haul-off shall be included in base bid. However, based on preliminary earthwork studies by design team, the site is expected to be approximately balanced, within specified tolerances.

o Explain how the allowances are handled. What is the allowance for playground equipment?

What is the allowance for skate park? Is the 10% contingency allowance supposed to be somewhere in base bid?

• RESPONSE:

o Contractor shall include allowances in bid, as specified on C0.0 and H1.00. Awarded contractor will then coordinate exact design, product, and installation with design team and owner. Contractor shall include the 10% contingency allowance into the unit price for each line item of the bid. Therefore, the actual price that will be paid for each line item is 90% of the value submitted.

o Explain how unit prices work. Is each unit price supposed to have everything priced into that item since there is no grading complete, erosion, or wall line items? Example: are we supposed to include all the grading, clearing, surveying, erosion, ect. for each line item?

The bid schedule is very confusing and the way it is right now there is now way we or subcontractors would ever break out numbers like this?

• RESPONSE:

o Unit pricing is broken into structures and defined project components. This is to simplify if items need to be removed from and/or added to the project. Site grading is a site wide issue but specific excavation that is required for various structures is associated with that specific line item.

o Clarify what the walls are? There is a detail of on pg, C7.1 for cast in place wall but elevation pages show segmental retaining walls. Also bid schedule shows a concrete wall but no segmented retaining walls.

• RESPONSE:

o Refer to H3.00. Walls shall be segmental retaining walls per H3.00 and specification.

Disregard detail on C7.1.

o In which Bid Line Item does the Electrical Site Lighting found on Sheets ES – 101; ES – 401; ES – 402 and ES -403 to be included?

o New Bid Form is provided under “Item No. 2” of this Addendum – See Line Item 97.

o What is the cost of the permits?

o All fees associated with City of Forest Park permitting are being waived by the City.

o Will the retaining wall require a permit? And if so at what cost?

o All fees associated with City of Forest Park permitting are being waived by the City.

o Will the Irrigation system to be designed by the Landscape Contractor? If so, then do you have a minimal Zone requirement.

o Refer to note on L1.00. Exact zone requirements will be coordinated with owner.

o Will Park Avenue be completely closed during construction; seeing we have work to complete on both sides of the street?

• RESPONSE:

o At this time there is no plan to close Park Avenue. After the award of this contact the successful bidder may provide a written request to the City for this closure. Requests for road closures will be complete with a traffic control and detour plan.

o Does the Limits of construction determine the linear footage of Construction Fencing required?

o Contractor’s responsibility to determine construction fencing quantities.

o Is there a certified land fill usage required by the city of Forest Park?

o No.

o Are any items listed for removal going to be removed by the city of Forest Park (reference sheets C2.0 & C2.1)?

• RESPONSE:

o At this time, contractor shall assume all work identified on C2.0 an C2.1 is to be performed by contractor.

o Can the limits of demolition be better defined as it relates to the existing pool and its components to remain?

• RESPONSE:

o Was the existing pool in operation during the summer of 2022?

o Yes.

o Is there a detail at the edge of slab for the new splash pad?

1.0 SUMMARY

The following is a brief summary of our pertinent findings and recommendations. The reader is referred to the remaining text of this report for elaboration on these items.

1. The property appears developable from a geotechnical standpoint but extensive undercutting of previously placed fill materials and water deposited alluvium is anticipated. Temporary dewatering during undercutting and stabilization of undercut subgrades with geotextile fabrics and crushed stone are anticipated. Some stabilization of existing subgrades is also anticipated for hardscape and any synthetic turf areas.

2. General subsurface conditions consist of previously placed relatively poor fill underlain in some areas by very soft water deposited alluvium followed by residual soils. No rock or partially weathered rock was encountered to the depths drilled.

Shallow groundwater will impact development. The shallow groundwater was measured as near as 3 feet below the surface as measured at the time of boring. Due to this being an active park, it was not possible to leave the borings open to obtain stabilized groundwater readings. Unstable surface soils were observed in the northeast portion of the site under the weight of the drilling equipment which may indicate groundwater near the surface.

3. We recommend previously place fill and alluvium be undercut from below foundations and slab areas.

The new structures may be supported on residual soil or new structural fill designed based on a soil bearing capacity of 1,500 psf. We anticipate that hardscape and landscape subgrade preparation will be routine in some areas, but other areas will require remedial undercutting and stabilization.

4. The on-site residual soils and most of the encountered previously placed fill soils are visually suitable for reuse as structural fill from a material standpoint but are wet of their optimum moisture and will require drying. The fill encountered in borings B-6, B-9, and B-13 appeared to be mixed with topsoil, so this fill material is not suitable for reuse as structural fill. This conditions may be more widespread than indicated since the fill was placed for playfields.

5. Excavations to the depths explored can be accomplished using conventional heavy earthmoving equipment.

2.0 PROPOSED CONSTRUCTION

We understand that you are planning the improvement of Starr Park in Forest, Park Georgia. Our understanding of the proposed construction is based on the provided “Grading Plan C4.0” , undated, by Croft and Associates, as well as a memo by Martin/Martin Consulting Engineers dated February 24, 2022 regarding the anticipated loads in the proposed structures. The planned improvements will include pavilions, a new pool house, amphitheater, restrooms, hardscapes, and associated stormwater control measures. Proposed finish floor elevations for new structures will be near the existing grade and minimal grade adjustment is anticipated to reach finished floor levels. We understand that all structures are anticipated to be 1-story with no below grade areas. The maximum column loads have been given as 28 kips and wall loads are expected to be approximately 1 kip per foot. The amphitheater will be metal frame and the other structures concrete block walls. No other details of the proposed construction were available at the time this report was prepared.

3.0 METHODS OF EXPLORATION

To evaluate the subsurface conditions, the property was explored by a combination of a visual site reconnaissance and drilling 20 soil test borings to depths ranging from 10 to 20 feet below the existing grade.

The borings were located in the field by measuring distances and estimating directions from identifiable site features. Therefore, their locations as shown on the Site and Boring Location Plan in the Appendix should be considered approximate.

The borings were advanced by twisting continuous hollow stem auger flights into the ground. At selected intervals, Standard Penetration Resistance Testing (SPT) was performed in general accordance with ASTM

Standard D-1586, and soil samples were collected for visual classification. Upon completion, the soil test borings were plugged and backfilled. The results of the penetration tests, when properly evaluated, provide an indication of the relative consistency of the soil being sampled, the potential for difficult excavation, and the soil's ability to support loads. A more detailed description of the drilling and sampling process is included in the Appendix of this report.

Soil samples recovered during the drilling process were returned to the office where they were classified in general accordance with the Unified Soil Classification System (USCS). Detailed descriptions of the materials encountered at each boring location, along with a graphical representation of the Standard Penetration Test results, are shown on the Soil Boring Records in the Appendix. Elevations on the Soil Boring Records were interpolated from the topographical contours on the plan provided to us and should be considered approximate.

4.0 SITE DESCRIPTION, GEOLOGY AND SUBSURFACE CONDITIONS

4.1 Site Description

The subject property is an existing park that includes a small stage, tennis courts, playgrounds, a walking track, pavilions, restrooms and other single-story structures, and various ball fields. The site generally slopes down to the southwest with approximately 15 feet of elevation change. Unstable surface soils were observed in the northeast soccer fields, pumping of the subgrade was observed under the weight of the drilling equipment.

The investigated site is immediately surrounded by single-family residences to the northwest and southeast, while it is bound by existing multi-level developments to the northeast and existing baseball fields to the southwest.

A review of selected historical aerial photographs and historical USGS topographic maps indicates the park was initially developed between 1955 and 1960 with modification through the years since. The 1960 aerial photograph indicates a pond in the northwest corner of the site. A creek exits the pond and flows to the south.

At the pond the drainage swale bends to the east and the old drainage swale continued “upstream” through this section of the park and under Ash Street.

4.2 Geology

The site is located in the Piedmont Physiographic Province of Georgia. The residual soils in the Piedmont are the result of the chemical and physical weathering of the underlying parent rock. The weathering profile usually results in fine grained clayey silts and silty clays near the surface, where weathering is more advanced.

With depth, sandy silts and silty sands are found, often containing mica. Below the residual soils, partially weathered rock is often found as a transition above relatively unweathered rock. In local practice, partially weathered rock is arbitrarily defined as residual soils with Standard Penetration Resistances in excess of 100 blows per foot (50 blows per 6 inches), and which can be penetrated by a power auger.

4.3 Subsurface Conditions

4.3.1 Pavement

Boring B-19 initially encountered about 2 inches of asphalt, which was underlain by 3 inches of base stone.

4.3.2 Topsoil

Most of the borings with the exception of borings B-11, B-18, and B-19 initially encountered 1 to 8 inches of topsoil and associated root zone.

4.3.3 Previously Placed Fill

Fill soils are those soils that have been placed or reworked in conjunction with past construction activities, grading or farming. Previously placed fill soils were encountered in all boring locations to depths ranging from

2 to 12 feet below the existing grade. The fill was classified as silty SAND (SM) with Standard Penetration Test

(SPT) results ranging from 1 to 13 blows per foot (bpf). Based on the SPT results, the soil represented by these samples would be considered poorly to variably compacted. Some of the previously placed fill encountered in borings B-6, B-9, and B-13 appeared to be mixed with topsoil. The fills were often underlain by very soft soils. It is unlikely that a high degree of compaction could be obtained for fills placed on this type of subgrade.

4.3.4 Alluvium/Possible Alluvium

Alluvium is soil that has been transported and deposited by moving water. It is typically encountered adjacent to water course and in the bottom of valleys like previously crossed the park site. Alluvium soil type can change drastically over short horizontal and vertical distances and can contain organics. It is difficult to distinguish between alluvium and fill that was placed from an alluvial soil borrow source. Apparent alluvium was encountered in borings B-3, B-5, B-6, B-8, B-9, B-11, B-12, and B-13 with initial contact occurring at depths ranging from 3 to 12 feet below the existing grade. The alluvium/possible alluvium was found to be wet during drilling. Standard Penetration Tests varied from 1 to 10 blows per foot but most of the alluvium was very soft.

4.3.5 Residuum

Residuum is soil formed by in-place weathering of the parent rock. In wet environments the residuum is often difficult to distinguish from alluvium. Soils classified as apparent residuum was encountered at all boring locations beneath the previously placed fill or alluvium/possible alluvium, where encountered. The residuum was classified as sandy SILTs (ML), silty SANDs (SM), and clayey SANDs (SC), and were of low consistency.

Standard Penetration Test results ranged from 1 to 20 blows per foot.

No rock or partially weathered rock was encountered to the depths drilled.

4.3.6 Groundwater

Groundwater was encountered in borings B-1 through B-3, B-5, B-6, B-8 through B-10 through B-14, B-16, B-

17, and B-20 at the time of drilling at depths ranging from 3 to 13 feet below the existing grade. Stabilized groundwater levels will be somewhat higher.

Groundwater fluctuations of 5 feet or more are common in this geology.

4.3.7 Infiltration Test Results

Infiltration testing was completed using an automated constant-head permeameter which measures the soil’s infiltration rate or saturated hydraulic conductivity (Ksat) at specified time intervals. Test locations and depths were selected by others. The testing began by performing hand auger borings by manually rotating a sharpened steel bucket auger into the ground at test locations P-1 through P-7 to depths of 2 feet below the existing grade. The test locations are shown on Figure 1 in the appendix. The proposed infiltration test could not be performed at location P-1 due to the presence of water 3 inches above the test elevation.

Infiltration testing was completed using an automated constant-head permeameter, which measures the soil’s infiltration rate or saturated hydraulic conductivity (Ksat) at specified time intervals. The depth of water in the borehole does not change during the measurement period and the change in weight of the water reservoir over the time interval is recorded. As a result, the rate of water supplied corresponds to the soil infiltration rate from the bottom and side surfaces of the borehole. Once a steady water consumption rate is reached, the resulting percolation rate can be determined. The infiltration rate is then calculated using the Reynolds and

Elrick solution. The resulting infiltration rates for the referenced test locations are presented in the table below.

The following table provides a tabular summary of the infiltration rate recorded at each test location.

Summary of Infiltration Test Results

Location

Depth (ft)

Test Elevation (Feet)

Infiltration Rate (in/hr)

P-1 2 977 n/a

P-2 2 968 0.1

P-3 2 971 0.2

P-4 2 977 0.2

P-5 2 968 1+

P-6 2 975 0.2

P-7 2 975 0.1

At the time of construction, we request the opportunity to evaluate soil conditions to verify that the conditions anticipated in design actually exist. Otherwise, we assume no responsibility for construction compliance with the design concepts, specifications or recommendations. The infiltration rate may be different at other locations and depths and is dependent on soil properties at the specific location. If variations become evident during construction, it will be necessary to reevaluate the recommendations of this letter after on-site observations of the conditions.

The conditions described in the preceding paragraphs, and those shown in the Appendix, have been based on interpolation of the results of the previously described data using generally accepted principles and practices of geotechnical engineering. However, conditions in this geology may vary intermediate of the tested locations, and even more so on previously developed property.

Although individual soil test borings are representative of the subsurface conditions at the precise boring locations on the day drilled, they are not necessarily indicative of the subsurface conditions at other locations or other times. The nature and extent of variation between the borings may not become evident until the course of construction. If such variations are then noted, it will be necessary to reevaluate the recommendations of this report after on-site observation of the conditions.

5.0 CONCLUSIONS AND RECOMMENDATIONS

The following conclusions and recommendations are based on the data gathered during this exploration, our understanding of the proposed construction, our experience with similar site and subsurface conditions and generally accepted principles and practices of geotechnical engineering. Should the proposed construction change significantly from that described in this report, we request that we be advised so that we may amend these recommendations accordingly. This report and the conclusions and recommendations provided herein are provided exclusively for the use of Falcon Design Consultants, LLC and are intended solely for design of the referenced project.

5.1 General

The fill encountered in the soil test borings was generally loose and appeared to be mixed with topsoil in some areas such as in borings B-6, B-9, and B-13. No documentation of the previous grading process was available for review. It appears the fill may have been placed in some areas on soft subgrade and in most cases apparently placed for the construction of playfields. It is not likely that fills were placed with the intent of structural support. There is the possibility that undetected areas of unsuitable soils were left in place or were placed during the grading, that pits have been dug and unsuitable soils or organics have been buried, or other unanticipated conditions may exist. This is a risk inherent in development on an undocumented, previously graded property. We recommend that any soils to remain in place be thoroughly evaluated by the engineer as detailed in Section 5.2 and 5.3 of this report.

The majority of the borings performed included a zone of very soft alluvial soils and shallow groundwater that will impact development.
