RFI RESPONSES FOR B1218 DPW15-123

PLEASE REFER TO RE-ISSUED DRAWINGS THAT WILL BE

SENT OUT FROM THE CONTRACTING OFFICE FOR

PLACING YOUR BID.

G1-RJS 1. please make today’s site visit attendees list available at your earliest convenience

The list of attendees was sent out on 2 September from the contracting office.

G2-RJS 2. is it the intent of the Government to issue specifications in a project manual format or are the specifications noted in the drawings as much as we might expect?

Specifications in a project manual format will not be issued. Only the specifications noted on the drawings and the Saber specs will be applicable.

G3-RJS 3. There is substantial ff&e remaining in the facility. Is the removal of this equipment the responsibility of the Government or the contractor?

The Government will remove the furniture.

G4-RJS 4. Does the government anticipate the bid date will be pushed with the issuance of amendment 0002?

Yes, the bid date will extended. See Amendment information for details on exact date and time.

G5-RJS 5. Would the Government considering revising the proposal submittal method to include email submissions? We acknowledge that, currently, proposals are to be ‘hand-delivered’.

Bids do not need to be hand delivered. They can be sent via United States Postal Service (USPS) mail, USPS express mail, United Parcel Service (UPS), Federal

Express or any other mail service as long as they arrive by the bid opening date and time at the place designated for receipt of bids in the solicitation. Due to firewalls that exist in our Fort Carson email system, emails are sometimes delayed, thus I cannot be sure bids would be received in a timely fashion when sent via email. Thus I cannot authorize bids being transmitted via email. However, I will be amending the solicitation to change the location and time for the receipt of hand carried bids to avoid individual(s) needing access through installation security gates.

G6-RJS 6. The solicitation references the transmission / submission of submittals to the Government in hard copy only (and in multiple copies). Would the Government consider accepting submittals electronically?

Submittals for equipment and products should be sent electronically.

G7-RJS 1. Please reference drawing sheet G-0.1 General requirements. Can these requirements be provided to the bidders or all reference to them be removed from the contract documents?

The SABER specs are not a part of the project.

G8-RJS 2. If an opening to be demo’d is not identified as note 1 or note 2, is there an acceptable default?

No

G9-RJS 3. FA drawing sheets 1.0 thru 3.0 reference, under general notes, a drawing FA-0.1. We are unable to find this particular drawing

This should be FA-0.0 and is not in order in the drawing package it is the last FA drawing new package this will be corrected.

G10-RJS 4. FN 4.0 references ‘architectural sheet A-100’ when indicating the removal and replacement of the existing floor drain (FD-1). We are unable to find this particular drawing. We note that the slab on grade (or at least a topping) in the areas well is badly degraded. Ids this slab to be replaced / re-topped?

There is no drawing A-100. Re-top the existing slab.

G11-RJS 5. AN-1.0 references a drawing A-0304 (in the area of the future conference room). Is this drawing relevant? We are unable to find this particular drawing.

There is no drawing A-0304. Drawing AN-1.0 is being changed to reference AN-7.0, which is the architectural details sheet.

G12-RJS 6. Will the existing ff&e be removed by the Government prior to the issuance of an NTP?

The Government will remove the furniture.

G13-RJS 7. Is there a specific keying protocol for storeroom, office, etc. locksets?
