SECTION 01 10 00

PART 1 – GENERAL

ITEM 1 - DESCRIPTION OF WORK

1.1 Background: This project consists of replacing the HVAC and control system in the Lincoln Home Visitor Center. The current HVAC system is old and inefficient. The chiller is seventeen+ years old and has reached the end of its life cycle. Constant repairs are being made to the chiller and condenser, as well as the pumps. The air handlers and evaporator coils are the original units that were installed in the 1970’s. The current coils are deteriorating. The controls, mixing valves and dampers are all pneumatic with numerous leaks, causing the air compressor to run more frequently than designed.

1.2 Work Covered by the Contract Documents:

A. Project Location: Lincoln Home National Historic Site, 413 S 8th St, Springfield, IL 62701.

B. Work consists of: The old HVAC system will be removed and replaced with a completely new HVAC system including: a new 30 ton high efficiency chiller unit, three electric steam humidifiers, three air handlers with economizers, 2 chilled water pumps, 2 heating water pumps, all new chilled and heating water piping. The existing boiler will be replaced with a high efficiency boiler and 2 high efficiency combo boiler/domestic hot water heaters. A direct digital control system will be installed to control the new HVAC system.

C. All work will be performed under a single contract.

D. Period of performance: Work shall be completed within approximately 200 calendar days after notice to proceed issuance. 60 days for shop drawings, material delivery as verified with manufacture material suppliers, and 60 days on site for active installation of the new system to substantial completion (POP is inclusive of 6 weather days), 7 days for final completion. Work on site shall not commence until critical equipment and materials required to complete the work are in the Contractor’s possession in order to minimize period of incactivity to the project’s progress once commencing. The Contractor shall obtain the CO’s written approval to proceed with active removals and construction within the Visitor Center upon confirmation that critical equipment and materials have been physically received.

a. The Contractor is expected to commence and remain actively progressing with the project work once issued the Notice to Proceed. The Period of Performance 200 calendar days are intended to account for extended equipment and material lead times to delivery and Contractor monitoring the seasonal winter weather forecasting to attempt to minimize periods of severe cold during active installation when the HVAC system is disconnected and temporary heating and protecting infrastructure is required (see Part

3.8 B of this document for temporary climate control requirements.) These two occurrences are recognized to be largely outside the control of the Contractor or NPS and therefore incorporated into the extended duration of the Period of Performance noted. The Contractor shall provide all reasonable efforts to commence and complete the project in the most efficient timeframe possible to the duration of disruption of HVAC service to the Visitor Center facility.
