Combined 7 Building Demolition 18 May 2021 Site Visit

Questions and Answers

1. Please provide the updated asbestos report survey for all facilities in question. If a new report is not available, please provide the existing reports for reference will an estimated quantity of additional asbestos removal no shown in older reports such as “Demolish 4” asbestos wrapped pipe @ 5000LF X PRICE = Total” to compensate for any unforeseen conditions found onsite and to not extend the bid due date.

Please see asbestos surveys and TCLP reports for Bldgs. 814, 820, 2431, and 2802, which accompany these questions and answers.

I have the old asbestos survey reports, but I don’t want to confuse the building demolition contractors by providing old reports.

2. Please confirm the Government will disconnect all utilities 5’ out from the building and salvage any electrical equipment prior to the KTR taking possession of the facility for demolition.

CED Answer: Yes, the privatized utility companies will disconnect all utilities to at least 5’ out from each building, and normally to the next primary connection point.

Dominion Energy Virginia (DEV) will disconnect the electrical service and remove electrical equipment, transformers, and other DEV equipment. After award, the contractor will need to communicate with the CED Project Manager (PM) and Dominion Energy on a timeline that will give DEV enough time to completely remove DEV equipment in each building before demolition begins on that building.

2.1 At Bldgs. 814 & 820, DEV will remove the transformers (green electrical boxes), and conductors (Primary and secondary cable) to the MDP. The Contr. shall contact DEV to schedule the disconnect at least (6) weeks prior to the start of demolition of the bldg. The first (2) weeks will be used by DEV to schedule their work. There is extensive work to be done by DEV (about 4 weeks) to make B814 and B820 safe for demo. If the Contr. needs the Basement sump pump, or their own Basement pump, or their own equipment to be powered after requesting electrical service disconnection, they will need to provide their own generator, or contract with DEV for temporary electrical service.

- DEV will remove the poles and lights on the basketball court and around the building. Additionally, there are (3) poles that will be removed but need to be replaced after demolition is complete. The foundations for these (3) poles need to be protected during demolition.

2.2 At Bldg. 853, the light pole will stay in place. DEV will remove the wire to Bldg. 853 prior to the bldg.

demolition. Use care to not damage the light pole.

2.3 At Bldg. 877, DEV will disconnect the bldg., but leave the electrical panel / ground boxes in place.

When you contact Miss Utility, make sure that they have marked the underground electrical conduits before you demolish Bldg. 877. Do not damage the underground electrical conduits or the electrical panel / ground boxes.

2.4 Bldg. 2431 utilities: See Answer to Question 84.

2.5 Bldg. 2630 utilities: See Answer to Question 85.

2.6 Bldg. 2802 utilities: See Answer to Question 86.

Dominion Energy Virginia (DEV) Answer (Rob Williams): Some buildings need to keep the electric energized until the contractor is ready, sometime this is after the contractor takes ownership, Dominion needs to know what building can be de-energized in advance.

CED Answer (Michael Reilly, CED Project Manager): Bldgs. 814 and 820 need to keep the electric energized until the contractor is ready (See Answer to related Question 11 for more information). The other bldgs. can be de-energized in advance.

3. During the site visit the Government discussed new curb/gutter and parking lot concrete at facilities 820/814. Please provide a drawing with LF of areas that receive this new work so all bidders are bidding the same SOW.

CED Answer: Due to cost, CED has decided to “not” replace the parking lot pavement that is removed.

Remove as little concrete paving at the bldg. as reasonable, but due to the foundation demolition, some if it will need to be demolished. Make clean concrete paving cuts that do not cause confusion and danger to the users of the parking lot. See sketches below:

Bldg. 814

Bldg. 820

4. Please confirm if pilings are located on bldgs. 814 or 820 or provide as-builts depicting this information so all bidders are bidding the same SOW.

CED Answer: CED does not have piling drawings of Bldg. 814 & 820, but expects that pilings exist. For foundation drawings, see foundation drawings in the original construction drawings. See example column detail below from original construction drawings, Sheet 19.

5. Will concrete crushing be allowed onsite at buildings 814 and 820?

CED, Environmental Element, Michael Shaffer (MS) Answer: We have had concrete crushers on Fort Eustis before. They [the contractors] should have their own VDEQ Operating Permit and should be familiar with dust suppression. If regulations are followed I have no concerns with their use.

CED (MR) Answer: Per CED, Environmental Element, Michael Shaffer, the Contr. is permitted to crush concrete IAW the regulations. See JBLE EMP 4.4.6.16 “Environmental Special Conditions, Environmental Management Procedures”, which was just revised 26 Mar ’21 (disregard older versions). Note: EMP

4.4.6.16 §6.1.2 Dust states, “[If the project is likely to create dust emissions, the following requirement applies] Mitigation of fugitive dust emissions shall be accomplished in accordance with 9 VAC5-40-90, Standard for Fugitive Dust/Emissions.”

9 VAC5-40-90 may be found at the following web site:

https://law.lis.virginia.gov/admincode/title9/agency5/chapter40/section90/

EMP 4.4.6.16 (revised 26 Mar ’21) may be found at the following web site:

https://www.jble.af.mil/Portals/46/Documents/Eustis%20Environmental/EMPs/Misc%20EMPs/EMP%20 4_4_6_16%20Contracting%20Environmental%20Special%20Conditions%20-%20JBLE- Eustis.pdf?ver=5saynAugvG14P6nbW_r_6w%3d%3d .

All concrete, whether crushed or not, shall be moved off Base.

6. Please confirm Fencing is required around ALL demolition sites at ALL buildings. Is privacy fabric required as well where fencing is utilized?

CED Answer: Fencing is required around ALL demolition sites at ALL buildings.

If installation of the fence is not feasible at Bldg. 2802, due to the active train track, coordinate with CED for an alternative solution acceptable to the Contractor and CED. The Contractor may instead need to prepare an alternate fenced area for the storage of their tools and materials.

7. What equipment will Dominion Power be removing from buildings (Transformers, Light poles, wires)?

See DEV Answer to question 28.

8. When will Performance Work Statement be revised?

CED Answer: Along with these contractor questions, or immediately after.

9. Will the government provide as-builts for the 814 and 820 structures for determining concrete dimensions, footer depths and below grade structures?

CED Answer: Yes, the Government will provide as-built original construction drawings for Bldgs. 814, 820, & 2802, and the original construction drawings for Bldg. 2431. As-built drawings are not available for Bldgs. 853, 877, and 2630.

Caveat: The as-built original construction drawings are provided as a courtesy and may have errors or omissions. The Contr. is responsible to field verify plans and dimensions as needed.

10. Will utilities be air-gapped, cut and capped and verified during the utility isolation performed by “others”?

DEV Answer (Rob Williams): Dominion will de-energize and remove line side conductors, transformers, and primary conductors.

11. Please confirm that there will not be any energized lines or existing utilities that remain in place that the contractor will need to protect and at the very least be made aware of.

CED Answer: There will be no energized lines or existing utilities that remain in place. See additional scheduling information in CED Answer to Question 2.

12. Please confirm that all dry transformers and secondary electrical will be removed by others.

DEV Answer (Rob Williams): Any equipment down line of the MDP (or switchgear) belongs to the Government. Dominion will remove the Lineside conductors entering the MDP.

CED Answer: The demolition project Contr. will remove equipment that remains, after DEV removes the DEV equipment.

13. At the site tour it was discussed that asbestos surveys were available but were dated from 10 years ago, the state will require more recent asbestos surveys, if this is the case will the government perform this revised asbestos survey? If the government will not provide updated surveys, will the contractor be compensated to perform required updated surveys?

CED, Environmental Element, Michael Shaffer (MS) Answer: Agreed that past lead based paint and asbestos records are out of date and incomplete and a new survey should be updated to reflect current site conditions. The 800 block did have several buildings that the crawl spaces contained asbestos debris in the soil. Some crawl spaces were abated and some were not.

If asbestos surveys are completed and lead content is at the level to be disposed of as demolition debris there should be no issues.

An Asbestos Abatement Plan will be required to detail how the removal will take place and steps to be taken to protect the health and safety of the work force and maintain environmental standards.

All required state and federal environmental Air Quality and asbestos abatement notifications should be made by the Contractor to meet time requirements.

CED MR Answer: See CED Answer to Question 1.

14. During the site tour it was discussed that the contaminated soil below the decking and structure of building 877 would need to be removed, please provide details on the contamination and extent of this material. Please provide documentation of any process knowledge of spills or other sources of this contamination.

CED Answer: Bldg. 877 was constructed in 1985, and is not expected to contain asbestos or lead-based paint. CED is not aware of any contaminated soil below the decking or structure of Bldg. 877. I remember discussing the footings at Bldg. 877: I don’t have as-built drawings for Bldg. 877, so I don’t know anything about it’s footings. I expect that it does have footings.

15. Has the government performed a hazardous material/universal waste inventory for items that will be transported to building 1208 for subsequent disposal by the government? If so, please provide quantities.

CED Answer: No survey of hazardous material/universal waste has been performed, except for the Govt.

provided Asbestos / Lead TCLP Reports.

16. It was discussed at the site tour that concrete shall not be crushed onsite. Is this applicable to a dedicated crushing machine due to dust emissions or does the government expect demolition crews to size reduce buildings minimally for subsequent disposal?

See CED Answer to Question 5.

17. It was stated during the site tour that footings, piers and pedestals would be demolished and removed to a depth of eight (8) feet below their current location, does the government expect the demolition contractor to excavate eight (8) feet below grade or eight (8) feet below the structure’s lowest point?

CED Answer: Excavate to a depth of (8) feet below the grade outside the bldg., except at the Basement, excavate to a depth of (8) feet below the Basement finish floor.

18. It was discussed that an additional 2 basketball courts and one gazebo with slab were to be added to the scope, please confirm.

CED Answer: Yes, demo a total of (4) basketball courts and (2) gazebos. Leave (1) basketball court and

(1) gazebo at Bldg. 815 (see annotated aerial photo below).

Demo basketball courts (DEV will remove light poles)

Demo smoking gazebos (including conc. pads)

Demo basketball court` (DEV will remove light poles)

Do not demo basketball court and smoking gazebo near Bldg. 815

19. At structure 2802, are the rail lines active? Please provide any train schedule information. Does work around these tracks require a railroad inspector or flagman? Who owns this rail line?

CED Answer: Yes, the rail line is active. Coordinate work with CED Quality Assurance Inspector (QA), who will check with the Range Officer for the schedule of when trains may be using the track. The Contr. may need to provide a watch person, to notify their workers if a train is sighted.

20. Will the government provide a map of available fire hydrants for water (dust control) as well as any costs for water use via hydrant if applicable?

CED Answer: Yes, see drawings below, provided by American States Utility Services (ASUS), of fire hydrant locations. There are no fire hydrants near Bldgs. 877, 2630, and 2802.

There will be no water utility cost to the contractor. Use the water reasonably without wasting it.

“The contractor may attach to the nearest fire hydrants at each demolition site, if available. Priority use of the fire hydrants will be to provide water to fight fires. For using the water hydrants, the demolition contractor shall call American States Utility Services (ASUS) POC at 757-888-0484 prior to the first hydrant hookup at each site and they will come out to the site. The contractor shall use a backflow preventer that has been tested and certified by a licensed individual on all hydrant connections and the backflow preventer must be approved by ASUS and protected from freezing during winter months.”

Bldgs. 814 & 820 – ASUS drawing of nearby Fire Hydrants:

Fire Hydrant (typ.)

Bldg. 853:

There is a fire hydrant approx. 350 lf away, but it crosses the drive twice. Contr. may connect to the fire hydrant shown in the location drawing above. Note that the hose would need to cross (2) vehicular drives used by patrons of Bldg. 828. Do not create a situation in which vehicles or pedestrians are unable to utilize the drives safely. Provide warning cones and tape. The hose could potentially be run around Bldg. 828, but the run increases to approx. 600 lf.

Alternately, the Contr. may connect to the hose bib at Bldg. 828, if it is operable. The Contr. may need to provide a faucet connection to the hose bib. See photos below:

Bldg. 853 Bldg. 828 Hose Bib

Fire Hydrant

Bldg. 877. There is no fire hydrant nearby.

The Contr. may connect to the in-ground faucet near Bldg. 877. As can be seen in the photo, the in-ground faucet is broken. CED has initiated a service order to replace the faucet. If the repair is not completed by the time the Contr. needs the faucet, the Contr. would need to either replace the faucet, or connect instead to the hose bibb at the entrance to Latrine Bldg. 867 (with warning cones and tape).

21. Does the government have any below grade drawings for anticipated UST’s (in use or abandoned) or fuel lines that may be encountered for each structure? Confirm previous use of UST’s and any closure performed on these tanks.

CED Answer: There are no known UST’s at any of the demolition sites.

22. Will the government require scrap value offset to the demolition contractors’ pricing?

CED Answer: No.

23. UFC1-900-01, is referenced in the specifications, however upon review that document is listed as canceled without replacement, please advise if a new specification addressing recycling and reuse of demolition materials has been developed or should be used.

CED Answer:

Exist. Scope text:

This scope of work shall include specified requirements, drawings and technical requirements set forth

Bldg. 2431 below. All work shall be accomplished in accordance with the specifications, site map, and terms and conditions of the contract.”

24. Para 3.15.2 Note: Concrete cannot be crushed on site and used as fill. The concrete must be removed off site. Question, can the contractor recycle and resell this material once off post?

See CED Answer to Question 5. See PWS §3.15.2 Crushed concrete cannot be used as fill. All concrete, whether crushed or not, shall be removed off Base.

25. Can the contractor work on multiple buildings at a time or does the government have a desired sequence?

CED Answer: The contractor may work on more than one building at a time, as long as a) they deploy a large enough work force that they don’t slow work to a crawl pace, and b) they provide a superintendent or alternate superintendent at each site.

26. Are there any COVID-19 social distancing protocols on base for contractor personnel when inside and enclosed space?

CED Answer: For current general safety protocols regarding Covid-19, see the Joint Base Langley-Eustis home page at ( https://www.jble.af.mil/ ).

For personnel working in confined spaces, the Contr. shall have their own Confined Space Program that meets OSHA Regulation 29 CFR 1910.146, and 29 CFR 1926 Subpart AA. The Contr. shall have a Confined Space Entry Permit that meets the above regulations; and at the job site each day for any confined space that gets entered, the Contr. shall keep a signed copy of this permit for possible review.

CED does not sign the permit.

OSHA Regulation 29 CFR 1910.146 may be found at ( https://www.osha.gov/laws-regs/regulations/standardnumber/1910/1910.146 )

OSHA Regulation 29 CFR 1926 Subpart AA may be found at ( https://www.osha.gov/laws-regs/regulations/standardnumber/1926/1926SubpartAA )

27. Please confirm that the government will terminate, cut and cap of all utilities (Electric, gas, water, sewer, communication, and storm) at the next junction away from the buildings, and at least 5’ from the buildings.

CED Answer: Yes, the government will terminate, cut and cap of all utilities (Electric, gas, water, sewer, communication, and storm) at the next junction away from the buildings, and at least 5’ from the buildings.

28. Please provided a detail scope of work that will be performed by Dominion Energy.

DEV Answer (Rob Williams): Dominion will remove services and equipment in conflict of the demolition.

It is the contractor’s reasonability to coordinate schedules. Some of the buildings need more work than others and will take much longer to complete equipment removal. Contractor is responsible to contact Dominion in advance if temporary power will be needed at any of the buildings.

29. Please provide all available as-built drawings for building 814, and 820.

CED Answer: Please see CED Answer to Question 9.

30. Can the concrete and block be crushed on site and left on the base for Government future use (other options would crushing and stockpiling could be performed at other location on the base for example at material staging area near building 2802).

See CED Answer to Questions 5 and 24.

31. Please clarify the scope/ extent of Grading requirement at building 2431.

CED Answer: Excavate sufficient soil that the slope is not a high hill as it is at present. It can be a gradual low-slope. The site should drain toward nearby streets, site drains, or natural drainage paths.

Please see “Typical Fill Section” on original construction drawing, Sht. FE 632-1.1 to see approx.

elevation of fill that the design planned in order to create the hill.

See FE 632-1.1

See FE 632-1.2

Please consider the FE 632-1 construction drawings only as approximate, since As-Built drawings of this bldg. are not available. (Note that the Sht. FE 632-1.2 generator room floor plan was reversed in actual construction, so all the doors would be on the same exterior wall.)

32. Please provide the depth below grad of the concrete bases (6 each) at building 2431.

CED Answer: The depth of the concrete bases on the south side of Building 2431 is not known.

33. Please clarify if the Storm Water Protection Plan (SWPP) will be approved by Base Environmental Department, or we must get approval from State of Virginia.

CED Answer: The State of Virginia. EMP 4.4.6.16 §8.1.3 states, “8.1.3. STORMWATER POLLUTION PREVENTION PLAN (SWPPP):

For LDAs over 1 acre, a full SWPPP submittal shall be developed in accordance with 9 VAC 25-870 and 9 VAC 25-880 and submitted to VDEQ for approval. No LDAs may commence without an approved

SWPPP.”

Note: The contractor will need to determine if the area of each bldg. demolition project is over an acre or not. If so, the contractor will need a SWPPP for that bldg. demolition project. For the purpose of this determination, each bldg. and its site area disturbed will be considered a bldg. demolition project.

34. Please clarify the scope/ extent of crawlspace contaminated soil clean-up.

CED Answer: Please see Asbestos Test results for Bldgs. 814 and 820. In addition to removing the remnant asbestos thermal insulation, remove the soil to a depth of 4” and to a width of 2 ft on each side of the remnant asbestos thermal insulation.

35. We are requesting to extend the response due date.

CED Answer: That is a question for Contracting.

36. Will the contractor be required to cut and cap the building utilities after they have been shut off?

DEV Answer (Rob Williams): – It is the contractors responsibly to communicate with Dominion Energy before construction begins to confirm all work is complete.

CED Answer: No, the contractor is not required to cut and cap the building utilities; but for electrical utilities, the contractor is required to contact DEV per the DEV Answer above. For other utilities, contact the CED PM and request verbal and email confirmation that the utilities have been cut and capped prior to demolition.

37. Should asphalt be used to repair / replace the parking lot in areas of demo?

No, see CED Answer to question 18.

38. For building 814 will we be required to demo the 2 light poles at the basketball courts?

CED Answer: No, Dominion Energy Virginia (DEV) will remove the light poles at the basketball courts to be demolished.

39. For building 814 and 820, PWS para 2.1.9 it is understood that we are to demo assumed pilings to 8 feet below grade and or basement floor. Do you know how many there are to demo?

CED Answer: Unfortunately, CED does not know if or how many pilings exist at buildings 814 and 820.

41. In the PWS para 2.1.2 it states to remove underground tanks. Can you tell us how many, what size and the materials they made of?

See CED Answer to question 21.

The PWS para 2.1.2 has been changed to state, “There are no known underground storage tanks (UST’s) at any of the demolition sites. If the contractor encounters any UST’s, please call the Government Project Manager (PM) or Quality Assurance Inspector (QA).”

42. Will up to date Asbestos and or Lead reports given to us so we can quantify the amounts and areas of abatement for each building?

CED Answer: Yes. See CED Answer to Question 1.

43. PWS para 2.2.11 states to remove any contaminated soil from crawl space. How much and contaminated with what, please explain?

See CED Answer to question 34.

44. Can you please send us the dimension of parking lot for building 814? Is the concrete have rebar, if yes; what is the number of bars?

See CED Answer to question 3.

45. PWS para 2.1.13.1. building 814 - Demolish building 814 parking lot pavement sections as needed to demolish electrical boxes with bollards, and storage boxes, at building and then replace with 8” concrete paving with 6” stone, in alignment with existing curb at corner.

The following questions were from (1) Contr.

48. Please confirm if a borrow area for topsoil and structural fill materials are available onsite. If so, would the contractor have to purchase that material or will it be provided?

CED Answer: CED has no borrow area for topsoil and structural fill materials.

49. Is there a base landfill available for this project? If available, is there any fees for using it?

CED Answer: There is no Base landfill available.

50. If base landfill available, confirm there are no sizing or processing requirements (other than it has to fit in the truck) for ACM or C&D to be disposed at the landfill(s).

CED Answer: There is no Base landfill available.

51. Are the utilities privatized? Are there any fees for the disconnection?

CED Answer: The utilities on JBLE-Eustis are privatized. The contractor will not be required to pay a fee for disconnection.

If the contractor decides to bring a project trailer on Base, they will need to apply for a site permit if they are outside the project fence. If they need water connection

52. Could the Gov't provide the as-builts/drawings including utilities?

CED Answer: The Govt. will provide available as-builts/drawings for Buildings 814, 820, and 2802, and the original construction drawings for Bldg. 2431. There are no available as-built drawings for Bldgs. 853, 877, & 2630.

In the PWS, The Government provided available utility drawings for each building.

See the as-built drawings for buildings 814 and 820, for additional utility drawings. These provide more clarity, but note that the actual conditions may have changed since the buildings/site was constructed.

53. What is the long term badging process to include accessing the secure area, and bringing in large machinery on trucks?

CED Answer: Use the same DBIDS Badging process as was used for the Pre-Bid Site Visit.

54. Is water available at each location within 10 feet?

CED Answer: No, but a fire hydrant is in the vicinity of each building, except for Buildings 877 2630 and 2802. See CED Answer to question 20.

55. Will utilities (i.e. water, electric) be provided by the Army or will the contractor have to pay?

- Water utilities, see CED Answer to question 20.

- Electrical utilities, DEV Answer (Rob Williams): The contractor is responsible for any temporary services needed for any of the locations.

56. Will backflow prevention devices be required at sources of water?

See CED Answer to question 20.

57. Please provide confirmation as to whether metals and machinery can be salvaged or if the installation is retaining these.

CED Answer: Metals and machinery may be salvaged or removed by the contractor per EMP 4.4.6.16, or brought to the Solid Waste and Recycle Center (SWRC), per EMP 4.4.6.16 “Environmental Special Conditions, Environmental Management Procedures”.

58. Do contractors need to perform ACM/ORM surveys for this project?

CED Answer: No. Please see May 2021 Asbestos / Lead TCLP Reports for Bldgs. 814, 820, & 2802. Please see 2017 Asbestos / Lead TCLP Report for Bldg. 2431.

The Contr. will; however, need to provide air sampling and final clearance reports per JBLE EMP 4.4.6.16.

59. Is it known when the ACM and LBP surveys will be issued to contractors?

CED Answer:

60. Are there any specific guidelines that include the handling of C&D and ACM waste?

CED Answer: See EMP 4.4.6.16.

61. Will contractor have to perform environmental monitoring during asbestos abatement as per US Army Corps of Engineers Manual EM 385-1-1 (Section 06.B.05, Page 92) as well as Federal, State, and Local requirements? Or will Government perform it?

CED Answer: The contractor will perform the environmental monitoring IAW EMP 4.4.6.16. The Contr.

will need to provide air sampling and final clearance reports per JBLE EMP 4.4.6.16.

62. Is there any UXO or any other special hazardous compliance requirements (CERLA, LBP, PCB, etc.)?

CED Answer: See EMP 4.4.6.16.

63. Can concrete/asphalt be used for backfill?

CED Answer: No.

64. If concrete and asphalt materials can be used as backfill is there a maximum size/gradation requirement for those materials.

CED Answer: Concrete and asphalt materials cannot be used as backfill.

65. Is there any constraints in recycling of painted concrete?

CED Answer: That will depend on the lead-based paint sampling and test reports that the Government provides.

66. Is there a diversion goal requirement?

CED Answer: See EMP 4.4.6.16 and EMP 434.6.7.

67. Do all onsite personnel need to be US Citizens?

CED Answer: That is a question for Contracting.

68. Is it the intention of Base to stabilize the disturbed areas with grass or gravel? If grass, what is the required grass mix for this project?

CED Answer: Grass. See the PWS §2.8 Site Restoration, and EMP 4.4.6.16.

Please note: Per the EMP 4.4.6.16, §11.7, topsoil, backfill dirt, grass, hay/straw, and mulch cannot be imported onto JBLE-Eustis from any of the Virginia Imported Fire Ant Quarantine Areas. See following web link to see a map of the quarantine areas:

https://www.vdacs.virginia.gov/plant-industry-services-fire-ant-suppressioneand-eradication.shtml

69. Please provide clarification on the topsoil requirement and area grading. Given the shallow footprint of some slabs on grade confirm that over-excavation will not be required to place 4 inches of topsoil.

Confirm that topsoil is meant to be materials similar to the surrounding area.

CED Answer: New topsoil shall be IAW the PWS §2.8 Site Restoration. Per PWS §3.13.2, “As part of the submittal process for back-fill dirt and top soil dirt, contractor shall arrange a visit to the submitted sources of back-fill dirt and top soil dirt with the CED PM and the Environmental Element POC.”

In a past demolition project, a contractor simply laid topsoil over the existing grade, creating unnatural hills, which adversely affected site drainage and topography. In order to have 4” of topsoil and provide good drainage, you may need to excavate. If 4” of good topsoil is already present IAW the PWS §2.8 Site Restoration, and the completed site drains well, that may not be necessary. The sites will need to drain well.
