Background

The purpose of this award is to install heating and ventilation mechanical systems for YMCA and Arctic Meat Company buildings complex currently under rehabilitation and located in Klondike Gold Rush National Historical Park. The proposed mechanical systems installation includes Government furnished indoor/outdoor heat pump units, buffer tank, heat recovery ventilation equipment, a ventilation fan, crawl space ducting, control systems and propylene glycol. Additional work includes supply of remaining ducting to connect ventilation equipment to crawlspace ducting and interior air return locations, as well as, the startup and commissioning of all mechanical systems.

Objectives

The Contractor shall furnish the necessary personnel, material, equipment, and services (except as otherwise specified), to install a new air-to-water heat pump (indoor and outdoor units), one buffer tank, heating system components, two (2) heat recovery ventilators (HRV’s), one (1) ventilation fan, and associated components necessary to complete mechanical systems installations as specified in the description of tasks below.

During the performance of the work, the contractor shall provide adequate professional supervision and quality control to assure the accuracy, quality, completeness, and progress of work.

This scope includes a minimum of 2 site visits.

The purpose of the initial site visit is to complete the following items:

• Inspecting the work location,

• Inventorying/inspecting previously procured ducting to be installed in the crawl space,

• Mounting/Installation of the HRV’s, heat coils and ventilation fan

• Determining the location of exterior and interior wall penetrations to complete the ventilation installation (NPS Day Labor will complete the work of creating these penetrations),

• Determine the remaining ducting take off to fabricate the remaining ducting needed to connect the crawls space ducting to the HRV’s and remaining ducting needed for 1st floor air returns and exterior air exchanges.

• Additional work that can be completed during the initial site visit include the following:

o Mounting/Installation of the crawlspace ducting, sealant and insulation o Installation of the Air to Water Air Source Heat Pump (ASHP) equipment, pumps, valves, etc… o Connection of ASHP hydronics to hydronic manifolds.

o Connection of radiant heating loops to the hydronic manifolds.

o Connection of ASHP hydronics to HRV heat coils.

The subsequent visit(s) will be to complete the following:

• Installation of any remaining ventilation and/or heating equipment, ducting, connection to heating manifolds and all other work specified in the contract documents not performed during initial visit.

• Installation of fabricated ducting to connect crawl space ducting to the HRV’s,

• Installation of interior air return and outdoor air exchange ducting to the HRV’s and ventilation fan.

• Ventilation and Heat Pump Start Up, Commissioning, and Control Sequencing.

It is the responsibility of the contractor to verify that all the information provided is accurate.

All work is to be completed in accordance with this scope, manufactures specifications, and other award documents, as well as all applicable codes and industry standards.

Contractor shall, without additional expense to the Government, be responsible for obtaining necessary licenses and permits, and for complying with any and all applicable federal, state, and borough, laws, codes, and regulations pertaining to the performance of the service that is to be rendered.

The Contractor shall take proper safety and health precautions to protect workers, the public, and property. The Contractor shall provide the Government all requested reports, and supporting material developed during the performance of the work. The Contractor shall ensure protection of historic structures during work.
