All other terms and conditions remain unchanged by this amendment.

Q1.

There are drawings in the bid set that are stamped “Not for Construction” dated March 28, 2016. Are we to use these drawings for our price proposal?

A1.

As mentioned as the pre-construction conference and site visit the plans and specifications dated 28 March 2016 would be replaced with final plans and specifications. The Final plans and specifications dated 14 June 2016 were uploaded to FBO.gov on 13 July 2016.

"Cutout dimensional characters" are meant to reflect exterior Bay #'s on the Overhead doors. They are found on A-201 & A-202.

Q4.

Page 1 of the SF1442 states time of completion is 540 CD, page 40 states it is 365 days.

Builders risk is not required.

Q7.

Metal Lockers 105113: 2.3-I calls for recessed door handle and latch, but 2.3-J calls for a projecting turn handle and latch. Please confirm the desired handle and latch.

A7.

2.3-I calls for recessed door handle and latch is the correct option. 2.3-J should have been deleted.

A8.

2.3-P, continuous Z base should be removed from specs. Drawings indicating section details with raised/tiled base is the desired detail.

Q9.

Drawing A603 Window and Storefront Types: Please provide clarification as to which of the elevations are storefront and which are aluminum windows. For example, elevation E10 is depicted as a window, but detail 1/A322 depicts it as a storefront.

A-603 is correct, as it shows Window types above the Header title "Window Types". Storefronts are labeled and located to the right of the window Schedule, but with "SF" designations Q10.

Reference drawing P-101. There is a new ¾” domestic HW recirculation line that begins in the ceiling of Conference Room 105 off the 1” domestic HW line. Should a balancing valve be installed there to control the hot water recirculation volume?

A10.

A balancing valve is not necessary in the hot water recalculation loop. There is a recirculation pump located in the boiler room that is controlled by an aqua-stat. The pump turns on/off to maintain the temperature of the aqua-stat. Nothing is achieved by adding a constriction (balancing valve) in the loop.

Q11.

Temporary Facilities & Controls 015000-3.4-I-4: Will temporary standpipes and hoses actually be required for temporary fire protection?

This is not anticipated as part of the proposed work, but they are included in the Specification to clearly establish them as Contractor responsibilities in the event they become necessary.
