Item No. 3A

REPAIR and/or REPLACEMENT OF ROOFING MATERIAL and ROOF SHEATHING

System T3010EN power unit.

The LULA hasn't been functioning for several years, and a preliminary assessment shows the cause to be an oil leak due to a faulty seal and not a malfunction of the mechanical and electrical systems.

It is the responsibility of the Contractor to verify and troubleshoot what the problem is. The Forest

ANALYSIS OF THE EXISTING HVAC INSTALLATION AND

RECOMMENDATIONS FOR REPAIR

Item No. 5A

ANALYSIS OF THE EXISTING HVAC INSTALLATION AND RECOMMENDATIONS FOR

REPAIR

This contract item is for the redesign, analysis, and troubleshooting of the HVAC (heating, ventilation, and air conditioning) system. Preliminary assessment of the system shows the original plans were not followed; there are no as built plans; the system wasn't commissioned, there are no operation manuals; the lower level single zoned system is causing excessive temperature variations;

there are no balancing dampers in any ducts, the building's existing HVAC has never been balanced; the HRVs (hear recovery ventilation)have never worked; and outside air exchange only works when the main AHUs are running.

There appears to be sufficient capacity of the A/C and heating systems and the two zoned upper level give acceptable comfort; but the problem is the lack of zoning in the lower level, lack of ability of the entire system to be balanced, and lack of outside air exchange.

The Contractor is responsible for the full assessment of the system's condition and problems, and to work with the CO to assure all HVAC problems are fully addressed.

The analysis of the existing system will include an complete HVAC analysis according to all applicable ASHRAE and ICBO Standards and , including but not limited to total heating and cooling capacity, air flow requirements for each room, duct sizes, fire dampers, ability to balance the system, indoor air quality, and outdoor air rates. This analysis will include actual measurements of the existing system. This item will include recommendations for repair and modifications of the existing system. Such recommendations will include, but not be limited to recommendations of making two zones in the lower level with VAVs, balancing dampers, proper functioning of the HRV and IAQ systems, CO2 sensors, and energy conservation. A Report will be given to the CO for approval which includes the analysis, recommendations, sketches, proposed product data, and cut sheets.

REPAIR AND MODIFICATION OF THE EXISTING HVAC SYSTEM

Item No. 5B

REPAIR AND MODIFICATION OF THE EXISTING HVAC SYSTEM

At the convenience of the CO, the Contractor's Report from Item No. 5A will be the basis of Item

No. 5B. If the scope of the needed repairs is significantly different from the preliminary assessment by the Forest Service or if the original bid price on Item No. 5B is significantly different from the

Report from Item No. 5A, this price may be renegotiated.

Repair and modification of the existing system will be the furnishing and installation of all required material; balancing of the system, documentation by measurement of compliance with ASHRAE

62.1; providing of required documentation in ASHRAE 62.1, Sec. 7.2 including balancing, operating and maintenance manual, HVAC control sequences, diagrams, design criteria, and as built drawings of the system.

All installation must be according to manufacturer’s instruction, sound construction techniques, and in a manner approved by the CO prior to construction. All design analysis, cut sheets, shop drawings, and product data will be submitted for approval by the CO prior to construction.

Contractor is responsible for notification and approval by the CO of the proposed schedule and any limitation that repair of the HVAC will impose on the ability of the building to be used.

Optional Item No. 5C:

REPLACEMENT OF THE EXISTING FURNANCES AND AIR HANDLING UNITS.

The contractor will provide itemized prices for total replacement of the existing furnaces, IAQ and other HVAC systems. This option will include a cost benefit analysis of the proposed replacements.
