Question 11 - Could micropiles be used in place of helical piles? Please advise.
Answer 11- The helical piers are designed and specified based on a site-specific geotechnical investigation, use helical piers as specified.
Question 12- The Pre-Bid Minutes emphasize that the “Total price of all items, including options should be listed in block 22 of the SF1442”. Per the SF1442, Block 22 is to be completed by the Government. There is also no indication in Section 00010 that the total price should be included on SF1442. Please confirm if Total Price should be included on SF1442 with
Bid Package.
Answer 12- The Total Price does not have to be listed on the SF1442.
Question 13- C101 directs us to remove and replace the existing handrails on the ramp and refers us to detail B1/C501. There are no ramp rails shown in this detail. Please clarify the requirements.
Answer 13- The handrails shown in the detail B1/C-501 are representative of the style, material, color, as well as the attachment requirements for all locations around the building including ramps.
Question 14- Are the construction drawings for the existing building available?
Answer 14- These drawings are for reference only and may not reflect the true as-built layout.
See attachments “Old Addition Drawings” and “ Old Original Facility Drawings”.
Question 15- Curtainwall spec 084400 para 1.3.5.5 calls out an “opaque” U-factor of no greater than 0.29. Glazing spec 088100 para 2.2 calls out a U-factor of 0.4 or less for the insulated glass units. Drawing A003 thermal shielding table lists fixed glass windows as having a U-factor of
0.40. Is it correct to assume that the entire curtainwall system (glazing + framing) should have a
U-factor of 0.40 or less, and glazing should be selected as required to meet this overall system thermal performance?
Answer 15- Yes, assume U-factor of 0.40 or less, and glazing should be selected as required to meet this overall system thermal performance
Question 16- The IG unit specified in glazing spec 088100 para 2.2 last paragraph lists an IG unit makeup of bronze tint (uncoated) on the exterior lite, and clear(uncoated) on the interior lite, with argon fill. Are low-E coatings on the IG units acceptable to improve the thermal performance of the IG units in order to meet the overall window system U-value requirements?
Answer 16- Yes, low-E coatings are acceptable
