4. Contractors are advised of the Government’s response to a question previously published in Amendment 0004 regarding the Bonding Capacity has been modified as follows:

QUESTION 4D:

In the Solicitation, page 16, (4) Bonding Capacity, it states this factor is a go/no-go to assess the offeror’s ability to provide an offer guarantee and performance & payment bonds sufficient to cover a project of this magnitude which is $10M.

Does GSA want a letter from our surety company for this section verifying the required information?

ANSWER:

FROM:

Yes. An Offer Guarantee (SF 24 - Bid Bond) is required for this project equal to 100% of the proposed price. If the proposed price is less than $10M, then the offeror shall provide a letter from their surety company verifying the Offeror has the financial capability to perform.

TO:

An Offer Guarantee (SF 24 - Bid Bond) is required for this project equal to 20% of the proposed price or $3 million, whichever is less. Reference The Solicitation Form C201 Section I.F. –FAR 52.228-1 Bid Guarantee (SEP 96), subparagraph (c) which reads:

The amount of the bid guarantee shall be 20 percent of the bid price or $3,000,000, whichever is less. (Page 8 of 34)

The Offeror shall provide a letter from their surety company verifying the Offeror has the financial capability to obtain payment and performance bonds in the amount of $10 million.

6. The following answers are provided for questions submitted by contractors regarding this

RFP:

A. QUESTION:

Pipe weld inspection criteria:

Specification section 232113.13 1.6B States that the piping welds should be made to ASME B31.9 standards. If the welds fail a visual inspection by owners third party, then random welds will be tested via X-ray inspection to ASME B31.1 Standards.

Due to the substantially different criteria in these two sections with ASME B31.1 being more stringent than ASME B31.9, a weld which is made to the ASME B31.9 standard cannot be expected to meet the inspection criteria for AMSE B31.1.

Please provide clarification?

ANSWER:

Piping welds should be made to ASME B31.1 (not B31.9) and tested per ASME B31.1 also.

B. QUESTION:

Spoils Removal Do all spoils need to be removed from the site or is there an area that we can dispose of somewhere on site?

GSA/IRS can find a temporary storage area for spoils but all spoils will need to be disposed of off-site.

C. QUESTION:

Document 003132-1.1.D references Document 002113 "Instructions to Bidders";

however, this section could not be found.

Please provide this section.

The section is not provided and the reference should be removed.

D. QUESTION:

Please confirm there is no cost associated with obtaining an ePM license for this project.

There is no cost associated with obtaining an ePM license.

E. QUESTION:

Please confirm the LEED submittals referenced in section 051200-1.6 are not required as the project is not seeking a LEED rating.

This is not a LEED project. Any reference to LEED submittal should be removed.

F. QUESTION:

It was mentioned at the site visit that there may be fire protection lines inside the existing building that need to be relocated in order to install new piping.

Please confirm this work is not required since it is not reflected in the drawings.

Fire protection piping was reviewed during design for conflicts. Several pipes are indicted to be relocated. If additional piping is to be relocated they should be noted on the required coordination drawings. If piping is required to be relocated for convenience, that shall be done at no additional cost to the government.

G. QUESTION:

It was mentioned during the second site visit that GSA intends on awarding all Options A through H associated with this contract, please confirm.

The GSA/IRS cannot make this commitment until final pricing is received. It is not immediately known if all options will or can be awarded.

H. QUESTION:

Temporary Boiler Operator Is a licensed operator required to operate the temporary boiler during the cooling tower testing period?

The manufacturer/provider of the temporary boilers would need to send a certified operator to install and run these boilers. They would need to be available during the commissioning process while the boilers are in use.

I. QUESTION:

Curbing Is curbing required between new blacktop and new concrete surfaces?

Blacktop pavement should be at the same grade as the path to the ramp. No curb required here.

J. QUESTION:

Cooling Tower Performance There is a wide range of required capacity between summer & winter duty. The winter duty requires more than double the cooling capacity of the summer duty. Summer Duty requires 6 tower cells to match existing and Winter Duty requires 12 larger cells. Further, leaving water temperature on the winter duty is below the factory recommendation for risk of freezing.

Please clarify.

The performance shall be based on summer conditions. The towers will do what they can for the winter. Flows and temperatures can be modified to obtain a valid selection.

K. QUESTION:

Electrical GFEP Breakers On drawing E101 note 2 and 5 call for 1P30A GFEP breakers to be added in existing panels. Panel 1DH4D1 and 1DH4D2 are I-Line type and the only available GFEP breakers are 3-pole breakers.

Please confirm the direction given on the drawings.

Specified heat trace controller and panel provides adequate ground fault protection.

Standard 30A/1P circuit breakers can be provided in Panelboards 1DH2D1 and 1DH4D2 in lieu of GFEP type.

L. QUESTION:

Electrical-Additional Breakers On drawing E101 and E102 they call for the addition of 1P20A breakers to panel 2U2A1, the Square D record drawings show that the panel is full of breakers.

Please confirm that there is space in the specified panelboard.

Panelboard 2U2A1 was furnished with the remaining spaces provided with spare breakers. Contractor shall utilize existing 20A/1P spare breakers for all required 20A circuits originating at Panelboard 2U2A1.

M. QUESTION:

Electrical-Additional Breakers On drawing E401 they call for the addition of one 1P20A breaker to panel 1R2D3, the record drawings show that the panel is full of breakers.

Please confirm that there is space in the specified panelboard.

Panelboard 1R2D3 was furnished with the remaining spaces provided with spare breakers. Contractor shall utilize existing 20A/1P spare breakers for all required 20A circuits originating at Panelboard 1R2D3.

N. QUESTION:

Electrical-Temporary Power Feed On drawing E802 they ask for temp power feed from MSS-1 and MSS-2, the record drawings show that there are spare breakers that could be used in lieu of adding new 1000A breakers.

Please confirm these are still available and are available for temporary use.

Existing spare breakers in MSS-1 and MSS-2 are Masterpact, and can be utilized in lieu of adding new 1000A breaker. Contractor shall provide new 1000A trip unit in existing spare as spare breakers currently contain 800A trip units.

O. QUESTION:

In reference Spec Section 013600.

Could it be clarified whether the government will be issuing the necessary, properly formatted COBie design files to the contractor immediately after award?

Could the software programs linked in the existing COBie file be listed in advance?

Since it is unknown how many corrections or changes may be needed to bring the format of the design file up to qualify standards indicated in the specifications, could this handled as an time and material allowance?

This specification section will be deleted from this project as COBie will not be used on this project.

In lieu of using the COBie system, GSA/IRS is requesting the attached Microsoft Excel Spreadsheet 'GDI Info - IRS CT Replacement'.xls be filled out in its entirety before the completion of the project. This is simply to provide data on the newly installed equipment like serial numbers, date of manufacture etc.

P. QUESTION:

Please clarify what is intended on drawing C501 under “Construction Sequence” where the construction time is indicated as approximately three months.

Revise Construction Time to 12 months.

V. QUESTION:

Cement Curb Drawing C502 Detail- Portland cement curb, reflects a detail where a concrete curb is shown between the new gravel and grass areas. The Civil drawings do not reflect the extent of this curb or locations where it may be required.

Please provide directive on if the curb is required and if so please indicate where it is required?

See Drawings C202, C203 and C204. A short length of 5 feet of curb is called for to guard the hydrant on the north side of the cooling tower.

W. QUESTION:

U/G Pipe and Fittings Drawing C502 reflects details for thrust blocks and buttresses for mechanical joint type pipe and fittings. Underground piping specification section 232113.13 3.2 calls out all butt welded joint, carbon steel, schedule 80 pipe and fittings.

Is the new underground pipe and fittings to be a different material than specified? If so please provide specifications for the piping and fittings required?

No. The underground pipe and fittings will be as specified. Use anchoring system per manufacturer's installation instructions.

X. QUESTION:

Buttresses / Thrust Blocks Drawing M405 Detail 1 Note 19 references Drawing C502 for thrust blocks/buttresses for the new condenser water piping. Underground piping specification section 232113.13

3.2 calls out all butt welded joint, carbon steel, schedule 80 pipe and fittings.

If the new Condenser water piping is per the specifications are concrete buttresses/thrust blocks still required?

Use anchoring system per manufacturer's installation instructions.

Y. QUESTION:

Soil Fill - Specification Section 312000, 3.13 SOIL FILL, B 3 thru 5 Engineered fill is defined as: Naturally or artificially graded mixture of natural or crushed gravel, crushed stone, and natural or crushed sand; ASTM D 2940/D 2940M; with at least 90 percent passing a 1-1/2-inch (37.5-mm) sieve and not more than 12 percent passing a No. 200 (0.075-mm) sieve. On-site soils or shale shall not be used in engineered fill.
