Please re-check this issue.

b. There are discrepancies between the excavation details and the plans. For example:

drawing E-116:

The plan refers to typical excavation detail no.44 which appears in drawing E-124:

The detail does not show the pipe’s required depth. Please provide.

Drawing E-116 requires 3 pipes. Please provide the relevant detail.

Response: a. Section 08.07.04 refers to interior conduits. Section 08.07.04 has been clarified.

c. The existing electrical lighting line is located along the western runway. Drawings A- 111, A-112.1 to A112.4 have been updated accordingly.

Question 158: Drawing E-83 Legend shows:

a. In additional feed drawings the red communication is marked orange and the black communication is marked red. Please advise whether the mistake is lines color or marking.

Response: Both alternatives are acceptable under Option 6. The contractor can bid on the alternative he or she chooses.

Question 162: Special specification chapter 09.04 – Exterior Plaster – requires exterior plaster coating. The architectural drawings do not include exterior plaster coating. Please confirm that no exterior plaster coating is required in this project. In case an exterior plaster costing is required, please refer to the relevant drawings.

Response: The exterior plaster coating is required only as a fix to correcting the finish of exposed concrete if during the inspection and acceptance process the finish does not meet contract requirements. The Contracting Officer or their representative will notify the Contractor of the deficiency. The steps to correct the deficiency shall be submitted by Contractor to the COR for review and approval. Special Specification Section 09.04 and 09.04.01 has been updated to provide clarification.

Special specification chapter 11.06 – Painting of Exposed Concrete Walls, section 11.06.01, item a:

Question 165: Both Option 1 – Construction of Western Runway, and Option 2 – Construction of Eastern Taxiway, must be completed within 90 calendar days after the award dates of the options. The suppliers of the lighting fixtures for both runway and taxiway informed us that these are long lead items for which the delivery time is 15 weeks. Taking into consideration the addition of submittals’ approval time, it is highly unlikely that the runway and the taxiway CLINs will be completed within 90 days. Please consider extending the performance period for the lighting fixtures only by 30 days.

Response: The period of performance for Option 1 and Option 2 has been extended to 120 calendar days. The work on existing runways has operational impacts and therefore, the western and eastern runways shall not be in a non-operational status for a period that exceeds 60 calendar days. SR-0 and the Price Schedule have been updated accordingly.

Question 166: Since the construction area is very large, please confirm that more than one gate may be executed in the construction fence.

Response: The suggested approach may be submitted by the Contractor in their Mobilization Plan for approval.

As of 10 June 2016

Question 167: During the site visit we were told that the site offices area may be located anywhere within the limits of the main works site. Please confirm.

Response: The contractor’s selection of the location for their site offices will need to be included in the Mobilization Plan that is subject to the review and approval of the COR. The southern infrastructural area labeled “AR” must remain operational and the ability for traffic to go in and out of this area must be maintained during execution of the project.

Question 168: The original issue “package” file contains architectural drawings in a pdf file titled “Attch_17a2_Architectural.” This file starts with drawing A-252. Amendment #2 contains architectural drawings in a pdf tile titled “Amend_0002_Attch_17a1_a2_Architectural_Revision01.” This file starts with drawing A-001, which is a list of drawings in the A set and seems to correspond with the combined drawing list.

The second drawing in this amendment 2 file is A-003. The drawing list on A-001 indicates the hardware list is on A-002, but I did not see that drawing. The door details refer to hardware sets on the hardware list. Was drawing A-002 issued? If not, please issue hardware list.

In addition, in reviewing the drawing list, drawings A-004, A-005, the whole of the A-100 series (with the exception of A-123), and drawings prior to A-252 are not contained in the documents.

Is my file corrupt or are these documents not yet issued?

Response: The original posting for the Architectural Drawings were divided into two pdf files:

Attch_17a1_Architectural - Contained Drawings A001 - A248 Attch_17a2_Architectural - Contained Drawings A252 - A801

Drawing A-002 was included in Attch_17a1_Architectural.

The “Amend_0002_Attch_17a1_a2_Architectural_Revision01.pdf” file only included those drawings that were revised under Amendment 02.

Question 169: The road connecting the work site and the spillage site might be damaged in the course of the work.

a. Please provide the typical section and bearing capacity of the road.

b. Please clarify who is responsible for repairing the road.

Question 170: Fuel Station – Building 700: the concrete slab below the underground fuel tanks appears on the architectural drawings, yet structural drawings for this slab are missing. Please provide.

Response: The details for the concrete slab of the fuel tanks are on Drawing F-006.

Solicitation W912GB-16-R-0030

Question 171: Section 38.04.08 requires that “The metering systems shall be manufactured by Liquid control M-5CX-2 type. We believe that this requirement is a sole source. Please confirm if this is the case.

Response: The Special Specification language has been updated to add “or equal.”

Question 172: Chapter 18 is difficult to follow/read as subsections are not formatted. Could this chapter be formatted for better readability?

Response: Yes, Chapter 18 has been formatted for better readability.

Question 173: There is a contradiction between the solicitation proposal preparation instructions and specific instructions in the Price Schedule.

The solicitation document (page 33 of 207) instructs as follows:

In the Price Schedule Revision 01, OPTION 1, it specifically states:

"Option 1 will not be awarded until 60 days after the base award NTP".

And Option 2 specifically states:

"Option 2 will not be issued until the Option 1 work has been completed and accepted by the government."

These contradictions in the documents will directly impact the schedule submittal.

Please clarify the starting date of Options 1 and 2 for the schedule submittal.

Response: The solicitation proposal submission instructions under Section 00 21 00 have been revised to match the Price Schedule and SR-0 as follows:

“For the purposes of this section only, the Offeror shall use the date of 02 January 2017 for Notice to Proceed and should prepare the schedule assuming Option 1 will be awarded 02 April 2017 (90 days after NTP) and Option 2 will be awarded 01 August 2017 (121 days after award of Option 1).”

Question 174: Please provide an additional information for sign painting details inside the hangars.

Response: Please see updated Drawings C-013 and C-014.

Question 175: Communication lines on sheets E-73 to E-83. Amendment 2, question 9, clarifies the red legend communication lines on sheets E-73 to E-83 are existing. The orange legend communication lines on sheets E-73 to E-83 appear to be existing as well, as they route in directions not shown on the drawings. Please confirm the orange legend communication line and

Solicitation W912GB-16-R-0030

As of 10 June 2016 associated manholes and signs are existing and not included in the scope of work.

Response: The orange legend communication line is a new line (i.e. PVC pipe 75 mm) and it's a part of the scope of work. No new manholes are designed as the new orange communication line connects to existing manholes along the route.
