City of Dublin

Can the area to the south west of the tank be used during the demolition as a work area? Is this area owned by the VA hospital?

Laydown yards will be delineated during pre-construction conference. The area around the tank belongs to the VA and can be used during demolition.

Is the new water tower being constructed near the old tank? If so in which general area? How far from the old tank? In Which direction? Clarifying that it will be across campus from the old tank.

Please see bid documents for locations.

Question # Question Government Response

I was sent a copy of the specifications and plans but did not receive a copy of the Geo-tech report for the tank site. Can you please forward a copy of the Geo-Tech report so that I can start design of the Tank and foundation. If a geo-tech report is not available, is there an assumed soil condition?

Geotech Tech Report is attached as Attachement #1C.

Is there a Geo-Tech report, with recommendations, available for the new EWT site? Spec section under Physical Data references results from core boring and test pits as part of the spec package.

Geotech Tech Report is attached as Attachement #1C.

Could you confirm that the covered walkway and drive-thru canopy on the plans is no longer in place?

These are no longer in place.

Page 8 of the specs references a requirement for unarmed guards depending upon the after-hours crime rate in the area. Could you advise if unarmed guards will need to be included in this proposal?

Unarmed guards are not required by the VA. It is the contractor's responsibility to protect his jobsite and equipment.

Are extended work hours and weekends a possibility? Several specialized subcontractors are from out of state and the extended hours will keep lodging and per diems under control.

Extended hours and weekends are acceptable but not required, except during a utility outage as required.

Per the Plans page CD102, General Notes, it references an “Asbestos and Paint Sampling and

Testing” report dated May 5, 2016. Is this report available for review?

Asbestos and Lead Paint report is attached as Attachment #1B.

The NAICS code listed in the solicitation is 237110. This code is listed in the Small Business

Administration NAIC Code List as General Construction in lieu of Specialty Trades. General

Construction only requires a minimum of 15% of the labor cost be performed by the SDVOB versus 25%. Page 5 pf 69; ITEMIZED COST BREAKDOWN requires that 25% of contract performance that will be incurred for SDVOSB personnel in accordance with FAR 52.219-27 –

Limitations on Subcontracting. Please consider changing to 15% to match the Small Business

Administration NAIC Code List.

Market research indicates there is several SDVOSBs that are registered with the specialty NAICS code selected. NAICS code will remain as stipulated in the solicitation.

27 Is it the intent of the V.A. to have the existing tank De Erected or can the tank be felled?

Specific means and methods of existing tower demolition may be determined by the

Contractor subject to the requirements outlined on Sheet CD102, Specification Section

024100 Demolition, all Local State, and Federal requirements governing the work

(including all OSHA Safety Requirements)

Could you provide the Geotechnical Report"? It was not included in the original documents but was referred to in the sections noted below.

Geotech Tech Report is attached as Attachement #1C.

We need an assumed bearing pressure to design to. In these cases, we normally assume

3000psf, just to design a base bid foundation, and that will change when we get the geotechnical investigation conducted.

Geotech Tech Report is attached as Attachment #1C. Use for development of foundation requirements for bidding.

The specs require Arc flash labels to be provided with specific incident energies, but the specs do not require the study to provide the calculated values. Is the contractor to perform an overcurrent coordination/arc flash hazard study to determine the values to go on the arc flash labels? Will the incident energy values be provided by the VA’s A/E or is the contractor required to hire an electrical engineer to perform the calculations?

Will answer in forthcoming amendment.

ES102 – Electrical items associated with the HVAC unit are incomplete. What size components shall be assumed for the BID?

Will answer in forthcoming amendment.

Smoke detectors are shown on drawing CU301. These items don’t appear to be addressed in the specs. What should happen when they detect smoke? What type of system are they connected to? Are there any remote annunciation requirements associated with the smoke detection system?

Will answer in forthcoming amendment.

What should be provided to serve as the service entrance disconnect and overcurrent protection for the normal side of the ATS?

Will answer in forthcoming amendment.

39 Where are the VFDs to be located on the CU301 layout? Will answer in forthcoming amendment.

Specs include Precast manholes with ladder and sump, however none appear to show up on the drawings. Are there any manholes in the project?

Will answer in forthcoming amendment.

ES102 and CU301 – Drawings appear to depict two different methods for mounting the transformer. Please clarify the mounting method desired for the transformer (wall or pad).

Will answer in forthcoming amendment.

Question # Question Government Response

ES102 – Keynote 4 – where does the power for the panel inside the generator enclosure come from (feeder, conduit, feeder breaker, etc.)?

Will answer in forthcoming amendment.

The specs require that the generator set be provided with transfer pumps to transfer fuel between a separate remote main fuel tank and a nearby generator day tank. The plans don’t appear to show a separate main fuel tank or associated fuel piping to a remote fuel tank. Are transfer pumps required? If so, what should they be connected to?

Will answer in forthcoming amendment.

The specs regarding main fuel tank refer to section 23 10 00 (the section was not included in documents). Is there a main fuel tank?

Will answer in forthcoming amendment.

The specs call for fuel flushing and testing per 23 10 00 (section not included). What are the flushing and testing requirements?

Will answer in forthcoming amendment.

The specs call for 24hr day tank and the drawings call for a 96hr sub-base tank. There is a cost difference between the two sizes, which size is required?

96-hour tank.

Drawing CU301 – shows a smaller, wall mounted ATS unit (does not appear to be of the bypass isolation type). Can the engineer clarify the ATS requirements? A bypass isolation draw out ATS, as noted in the specs, would be much larger, likely requiring a much larger footprint. The specs call for a 4” pad under the ATS but drawing CU301 depicts a wall-mounted unit. How will the ATS be installed?

Will answer in forthcoming amendment.

What raceway shall be provided for the underground fiber optic cable? The scaled drawings do not show both ending termination points for the fiber. What min. cable and raceway lengths should the bid include for the fiber optic run?

Approximately 240 feet.

There is antenna attached to the existing water tower with cables running to a small portable building (with a window unit AC). Drawing CD102 calls for the relocation of the communication equipment (keynote 8). Does this note refer to the small portable building and antenna on the water tower?

Turn over portable building and antennas to VA.

What electrical services/feeders shall be provided at the new tower location to accommodate the relocation of the communications equipment?

Will answer in forthcoming amendment.

51 What is the scope associated with the existing portable building? Turn over portable building and antennas to VA.

Many VA facilities own and operate their own MV electrical campus distribution. Who provides the

“New Utility Transformer”? If utility, are there any metering requirements for the contractor? If the contractor is to provide, there are no specifications associated with the MV transformer (size, type, loop-feed, terminations, grounding, fusing ….). Who provides medium voltage primary to the

“New Utility Transformer”?

Will answer in forthcoming amendment.
