9 Section II.D. Technical Proposal (1) Experience-Tab A requires that a joint-venture team submitting a proposal for the

Eisenhower Memorial project satisfy the experience factor, including a minimum of (one) 1 CMc project and three (3) memorial construction projects, as a joint venture. Given the limited number of memorial projects and the tendency for joint ventures to be formed for significantly larger projects, would

GSA consider allowing joint-venture offerors to qualify if two of the four required projects, including at least one CMc and one memorial project, were performed by the joint venture with the remaining project requirements coming from the individual joint venture members?

This item is being clarified in an Amendment.

36 Note 2 on sheet DC1-4.3 indicates the waterline to be removed in the triangle formed by Maryland Ave, Independence Ave, and

6th St. What size is this line? Is the tee to be cut out, or plugged, at the existing main? What size is the existing main in

6th St.? Does this line tie in to anything in Maryland Ave?

Per DC1-1.3 - Size of line is unknown. Existing main in 6th St is 8" according to DC Water and it ties into a water line on Maryland Ave to be removed (see note 5 on DC1-1.3).

37 Note 2 in the middle of Maryland Ave shows removal of a 6” waterline, but does not show where this line comes from, or goes. Is this line to be cut, capped, and blocked at both ends?

Please Clarify.

6" water main in Maryland Ave to be removed without replacement.

38 Note 3 calls out removal of the 4-stem valve at the intersection of Maryland Ave and 6th St. Will we be required to install a new cross and 4 new valves in this location? If so, will the new cross need to be restrained and/or blocked on the east side, where the existing line is to be removed? Will you provide a design for the blocking?

Existing 4-stem valves will be replaced with cross/tee and standard gate valves or as directed by DC Water.

39 DC1-1.3 calls out a temporary water valve on the 8” line in

Maryland Ave near 4th St. This valve will probably need to be restrained. Will you provide blocking details?

Valve will be installed per DC Water standards as DC Water has reviewed the plans and provided comments. DC Water details as recommended by them can be found on sheet C1-5.2.

May 16, 2017

40 Note 3 on sheet C1-1.1 calls out a new 10” water service running to the Eisenhower Building, but plan sheet DC1-1.3 shows the existing pipes to be 8”. Is this correct? Will the new service incorporate a 10”x8” reducer between the cross and the meter vault? Please clarify.

The existing water service is on 6th St is 8”. An 8”x10” increaser will be required at the connection to the water main in 6th St and 10” will be run from the increaser to the LBJ building. This will be clarified

41 Enlarged Utility Plan 1 (Sheet C1-1.2) shows the new water service (10”?) tying into the “Existing 4-stem Valve”. This valve is to be removed in the demo plan. It does not show it being replaced. Please clarify.

Comment is accurate. Reuse existing valve.

42 Note 2 on sheet C1-4.1 calls out “Existing Fire Hydrant to

Remain”. This conflicts with Sheet C1-1.1 Composite Utility

Plan Note 17, which calls out to “Replace Existing Hydrant with

New Hydrant”. Please Clarify

Replace existing hydrant with new hydrant.

43 Note 3 on sheet C1-4.1 refers to “WMH-2”, but none are indicated on the plan. Please clarify

Note 3 will be revised to indicate WMH-3.

44 Note 5 on sheet C1-4.1 refers to the 3” Life Safety Line and

Valve going to the Information Building, but No Valve is shown on the plan. Please Clarify

Valve is not required.

45 Profiles W-1, W-2, and W-3 on sheet C1-4.4 all indicate tying into the existing water main with 12” Tapping Sleeves and

Valves. It is our experience that DC Water will not allow

Tapping Sleeves and Valves installed on their system, but rather will require a cut-in Tee using sleeves and a solid pipe.

Please Clarify.

DC Water has reviewed the plans and has not indicated an objection to the Tapping Sleeves and Valves proposed in the plans. We are continuing to coordinate with DC Water and will not propose any tie-ins to their system which are not allowed by them. Price as shown.

46 Profile W-4 on sheet C1-4.4 shows the 10” pipe tying into the existing system at sta. 0+00 with a Tapping Sleeve and Valve.

This is in conflict with several other plan sheets which call out tying in to the existing 4- stem valve, which is called out to be removed in the demo plan. Please clarify

Existing 4-stem valves will be replaced with cross/tee and standard gate valves or as directed by DC Water.

47 Profile W-5 on sheet C1-4.4 indicates tying into an existing 9”

Waterline with a Tapping Sleeve and Valve. 9” pipe will be a special order. The same profile shows connecting to the existing 9” water with an 8”x6” Fire Hydrant Tee. Please clarify.

This should be existing 8" water line.

May 16, 2017

48 Note 10 on S303.2 states to re-route sprinkler branches and heads to below the temporary framing. How many sprinkler heads will need to be relocated? How much of a drop will the sprinkler branches need to be relocated? How many temporary walls will be installed creating separate occupancy areas? Will sprinkler coverage be required above the temporary frame?

Note 10 on S303.2 states to re-route sprinkler branches and heads to below the temporary framing. How many sprinkler heads will need to be relocated?

Response: The sprinkler layout and approximate repair areas are shown on S102.1 and S102.2.

How much of a drop will the sprinkler branches need to be relocated?

Response: See 3/S303.2. the intent is to drop below the temporary framing. At most, it should be no lower than the bottom of the existing concrete girders.

How many temporary walls will be installed creating separate occupancy areas?

Response: These are schematically shown on S101.1 and S101.2, but will depend on the layout of the concrete repairs from the contractor’s survey. The contractor must submit the temporarywall layout as part of his protection plan submittal.

Will sprinkler coverage be required above the temporary frame?

Response: The temporary framing will be tight against the slab, so no.

49 The material ID legend on drawing A0-1.6 calls out GL-4. This glass does not appear anywhere else in the drawings. Please provide locations for GL-4.

The GL-4 for is for the Glass in the table vitrine millwork covered under spec section 062023 and shown on A6-13.4

79 General - Would it be possible to extend the RFI deadline to

May 16, 2017?

The RFI deadline will not be extended. The Offeror may submit questions past the RFI due date and the Government will attempt to answer them in a timely manner.

80 General - Would it be possible to schedule another site visit for the LBJ Electrical and Mechanical Rooms?

Yes, we will hold an additional Site Visit on Wednesday, 5/17 at

1:00pm. Please limit attendees to 2 per Offeror. Attendees should meet at the C Street entrance of the LBJ Building no later than 1:00pm to be screened by Security.

81 Do you anticipate extending the bid date for the Eisenhower

Memorial Project? We have had feedback from a number of bidders that they would bid the project if the date were pushed back a week. I think that having it due on the Friday of a big holiday weekend is keeping a lot of subs from bidding.

We do not anticipate extending the bid date for this project.
