1. PROJECT INFORMATION:

A. PROJECT NUMBER: XQPZ160148

B. PROJECT TITLE: Sust/Rpr AHUs – W Fairchild Hall

C. PROJECT LOCATION: 2354 Fairchild Hall, USAF Academy, Colorado

2. DESCRIPTION OF PROJECT:

A. PROJECT BACKGROUND: Most of the AHU systems in 2354 Fairchild Hall are original to the building and in operation since approximately 1960. They are also “Combo” coils which provide cooling or heating, but do not switch automatically.

The “Combo” system is converted to heating in September and converted to cooling in May. The HVAC consists mainly of air handling units and reheat coils serving spaces. Reheat coils were retrofitted with VAV boxes in the early 90s.

The building is served by the Central Heat Plant which provides high temp hot water of up to 400 degrees. The chilled water is generated at the Fairchild Hall chiller plant, with cooling towers located at the Aero Lab. This project will upgrade AHU equipment in mechanical rooms: 1-H2, 1-D2, 1-E2 and 1-B2, consisting mainly of 14 existing air handling units and associated equipment. Most piping and ductwork insulation is original and may contain asbestos.

B. CONSTRUCTION SCOPE: The Contractor shall execute the project as shown in this SOW, Project Drawings, and Specifications. In case of conflicts between documents, the order of precedents will be Contract, SOW, Specifications, and Project Drawings.

GG. There are many motor/pulley assemblies for existing pumps and exhaust fans that are protected with expanded metal. It is our understanding that these existing covers do not dully protect workers in the area and do not comply with OSHA regulations. Should we include costs to furnish and install sheet metal protective shrouds that do meet OSHA regulations? If yes, please provide a detail for this requirement.

1. Answer: Work to be completed by USAFA prior to award of this contract.

HH. Revised SOW dated 13 Dec 2019, paragraph 4.A.5 includes cleaning existing ductwork throughout the project area. Drawing page G-002, General Construction Note 5, states the majority of work is anticipated to occur during normal business hours and the Contractor is to submit a construction schedule with phasing plan to the 10 CONA Contracting Officer for approval. There is no additional information provided in the bid package for the intended various phases of the project that relate to duct cleaning. Specification section 23 01

30.41 directs the Contractor to provide a Coordination Plan and Work Execution Schedule prior to commencing work. Is the Contractor to assume the majority of duct cleaning activities can occur during normal business hours? Duct cleaning activities may require existing air handling units are temporarily shut-down in areas on an extended basis. Is temporary heating or cooling needed in areas affected by duct cleaning? Without this information the contractor’s ability to provide a competitive and reasonable bid for this CLIN may not be possible.

1. Answer: Refer to 4.K.9 for clarification. Temporary heating or cooling specifically for duct cleaning is not required.

II. There is a note on many of the M400 series drawings that states, “UPGRADE

EXISTING CONTROL PANEL COVER BY REMOVING UNUSED GAUGES IN

DOOR COVER, REPLACE DOOR COVER OR ADHERE NEW WATER-TIGHT

FRON PLATE, PROVIDE DOOR GASKET, AND SEAL OR REPLACE

CONTROL CONDUIT SET-SCREW FITTINGS WITH RAINTIGHT GASKETED

COMPRESSION TYPE.” Is this necessary since there is no high temperature hot water in these mechanical rooms? To get a watertight enclosure, Siemens would recommend replacing all enclosures with Nema 3R panels and providing rain tight conduit fittings.

1. Answer: Note regarding upgrading control panels is in regard to upgrading panel doors but not to waterproof the entire panel.

JJ. Will the users and their suppliers/equipment between mech rooms 1E2 and 1D2 be relocated during construction or are we required to construct a swing space for them?

1. Answer: No swing space shall be required.

KK. Is there a comprehensive Hazardous Materials Sampling report for all vertical and horizontal ductwork and envelopes beyond the mechanical rooms? If so, please provide. If not, how should we bid sampling (abatement will be added by modification) in these areas?

1. There is not a HAZMAT report for ductwork beyond the mechanical rooms. Duct cleaning and air balancing should be executed in a manner to not require HAZMAT testing where possible.
