REQUEST FOR INFORMATION (RFI) #1 21 MAR 2018

Q1. Please provide drawing containing existing sprinkler layout. Reference Drawings 1. Brac

Upgrade F-16 Engine CIRF prepared by Hanson Professional Services, Inc. Dated 6/17/11.

A1. Please see the attached Plumb – FP attachment with this document. It is the contractor’s responsibility to coordinate with the existing site conditions.

Q 2. A subcontractor is stating that the monorail & hoist spec requirement 2.2 (B) (7) LIMIT

SWITCHES, found in specification section 14 51 00 on the top of Page 6, is not able to be met based on the manufacturers listed under 2.1 (B). “The model hoists that are specified under 2.1

(B) do not offer a geared upper and lower limit switch assembly.” Please clarify?

A2. During design, Hanson worked with two (2) hoist manufacturers to ensure the system specified could meet the requirements needed for the space. The limit switch requirement was part of the hoist package recommended by one of the manufacturers, Gorbel: Model Number

94801 GECH-1/2-S-16-SSP-230-10-1-C.

If a geared limit switch is not available, an electric limit switch may be used.

The limit switches prevent the block from being raised too high damaging the hoist itself or being lowered too far allowing the chain to fully unspool from the gearing.

Q3. Specification Section 003126 Part 1.1.C states that hazardous materials have been previously removed. Specification Section 012100 requests that allowances be included for hazardous material abatement. Specification Section 012200 requests unit prices for hazardous material abatement. Specification Section 013543 Parts 3.2 and 3.4 states that asbestos and lead-based paint are included in this project. Please confirm that the abatement allowances are to be carried in our base bid and that the unit prices are required. If unit prices are required, will

Section 00010, Solicitation Contract Form be modified for incorporation of unit prices or should that be submitted on a separate sheet with our proposal?
