QUESTION GOVERNMENT RESPONSE

24. MH 345 in the Structures excel file states that it is a

72” Pre Cast Manhole. The drawing detail states MH

345 is a 96” Hydro Dynamic Separator. Are we installing both a 72” MH and the 96” separator or just one. Please clarify.

CU107 and CU116 shows manhole 345 is a 96” Hydro

Dynamic Separator. Only the 96” manhole is to be constructed at MH 345.

The excel spreadsheet was provided to help Electrical and Signal Trades locate the structures required for their cabling as they are located on CIVIL sheets and seems this may have caused some confusion. The only relevant tabs on Attachment 11 are labeled CU116 (for CIVIL structures), CU117 (for Electrical Structures), & CU118

(for Signal Structures) which are identical to those same

Drawings sheets. The other tabs on the excel spreadsheet are to be completed by the Contractor as

As-Builts. A revised sheet has been attached, however no data has been revised to correlate with the RFI changes noted in this amendment.

See RFI response #56 for additional clarification.

No existing drawing information is available. It should be assumed that there is an existing foundation below the standing pole barn structure of the building and that the slab on grade could be 5”, unless thickened further below building structure.

38. Can you clarify what class of Ductile Iron you are looking for, for watermain piping?

Thickness Class 52

39. Can you please give some more detail/information on the Sump Pump Removal shown on CD102?

The sump pump was a temporary drainage solution to alleviate flooding near the property line in the area. A temporary power line and pedestal was installed to the area to power a small pump (pump size unknown, but likely ½ HP). The pump was placed in a shallow sump and the discharge pipe ran stormwater to the north toward the wetland area. Once the new drainage ditch and system is in place, the contractor shall remove this temporary power line, pump, and discharge pipe. This is a 120V 20-amp circuit ran with type UF cable back to the electrical panels that feed the construction trailers.

40. Ref drawing CU102 and Specification 33 51 00- A new natural gas line is shown from building 17 which runs north and east to service future buildings. When contacting Consumers Energy at number shown on drawing VA101, I am told they need the total connected load in MCFH for each future building that will be constructed, the delivery pressure, and the estimated annual usage in

MCF/year OR estimated operation schedule (for example 24 hours a day for 365 days a week or 16 hour days on weekdays) to be able to provide a cost estimate. Will this information be forthcoming?

This is privately owned, and consumers will not be involved in the installation. Calculations for sizes and pressures have already been completed for future connections.

Final pressure to the future buildings would be 2psi and once constructed, dropped to 7-14 in wc at the building entry.

ITEM

NO.

QUESTION GOVERNMENT RESPONSE

41. Is Camera 29 a License plate Camera. Yes, Camera 29 is a Fixed License Plate reader. Keynote

2 is applies to this camera.

42. In accordance with Solicitation the project type is identified as a 237990 NAICS Code Heavy Civil

Construction. This is the first Solicitation we have encountered being issued under this NAICS code.

The project involves multiple trades and required coordination requiring the Prime Contractor to perform the “primary and vital” requirements of

NAICS code for General Contracting which is

“management, supervision, and oversight of the project, including coordinating the work of various subcontractors, but not actual construction performed”. We have identified subtrades involved to include Earthwork, asphalt, concrete, site utilities, electrical, etc.

We respectfully request that the NAICS Code that this project falls under be revised to 236220 for

General Contracting. This will result in more competitive bids by qualified General Contractors.

We believe that the requirements of the Technical

Section requiring past performance of (2) awards under the 237990 exceeding $3.5mm will exclude the majority if not all of the SDVOSBs currently interested in this Solicitation.

Careful consideration was given to choosing the most appropriate NAICS of this acquisition as it relates directly to the project specifications and details found in

RFP package.

The code 237990 – other heavy and civil engineering construction was chosen because it contains the highest relevance and dollar values associated to work identified in the cost estimate, specs, and drawings; specifically earthwork, utilities, heavy machine operators, and low voltage supply and install. Only a small portion of building construction is present, which is best represented by 236220 – commercial and institutional building construction. Although most VHA projects are building construction, this project is mostly civil-based.

There may be more SDVOSB firms with 236220, but

SDVOSB competition also exists under 237990. The contracting teams sustains its decision to solicit and award with NAICS 237990 to best support the project while also meeting Veteran’s First contracting laws.

ITEM

NO.

There are two ditch crossings on the north fence line.

60. Will I be able to install the fence before the fiberoptic lines are buried next to the fence lines?

Coordinate with the low voltage contractor, however the fence is primarily on the property line so there shouldn’t be any issues.

61. What section of the fence are these temporary fence arrows pointing at? Looks like both are pointing at the 7’ security fence.

The temporary fence is between the arrows, approximately 274 ft.
