About this file

Written by GovTribe AI · Jul 10, 2024

This document contains construction drawings related to the replacement of the HVAC system and roof at the Alan Bible Visitor Center at Lake Mead National Recreation Area in Boulder City, Nevada. The drawings include a roof demolition plan, roof plan, and various roof details. The key scope of work includes:

Replace rooftop HVAC units AC-2, AC-3, and AC-4
Replace exhaust fans EF-1 and RF-2
Replace split system fan coil/condensing units FC/CU-4, 5, 6, and 7
Replace ductwork and diffusers serving office and basement spaces
Reconfigure lobby supply and return ductwork
Provide supply air to restrooms from AC-2
Remove and replace the entire roof system including membrane, insulation, and flashing

The drawings also include structural details for patching existing roof openings and framing new openings. This appears to be part of a larger federal solicitation to replace the HVAC and roof at the Alan Bible Visitor Center.

UNIT TO BE PROVIDED WITH MANUFACTURER'S STANDALONE CONTROL AND SHALL BE ABLE TO, AT A MINIIMUM, PERFORM THE FOLLOWING:

OCCUPIED/UNOCCUPIED DESIGNATION:

THE EQUIPMENT FACTORY CONTROLLER SHALL INITIATE OCCUPIED AND UNOCCUPIED MODES PER SCHEDULES FURNISHED BY THE OWNER.

WARM-UP/PRE-COOL MODE:

EQUIPMENT FACTORY CONTROLS SHALL PERFORM WARM-UP/PRE-COOL SEQUENCE BASED ON PROGRAMMED BUILDING OCCUPIED/UNOCCUPIED SCHEDULE. IF OCCUPIED SETPOINT IS MET PRIOR TO THE SCHEDULED OCCUPIED CHANGEOVER TIME BY MORE THAN THE OCCUPIED ENGAGEMENT ALLOWANCE SETPOINT, THE WARM-UP/PRE-COOL RUN-TIME SETPOINT SHALL BE ADJUSTED 5 MINUTES LATER. IF OCCUPIED SETPOINT IS NOT MET BY THE OCCUPIED MODE START TIME, THE WARM-UP/PRE-COOL RUN-TIME SETPOINT SHALL BE ADJUSTED BY 5 MINUTES EARLIER.

OCCUPIED MODE - SUPPLY FAN SPEED CONTROL:

EQUIPMENT FACTORY CONTROLS SHALL MODULATE SUPPLY FANS AS REQUIRED TO MAINTAIN THE SPACE TEMEPERATURE SETPOINT.

OCCUPIED MODE - RELIEF FAN SPEED CONTROL:

WHEN ECONOMIZER COOLING IS ENABLED, EQUIPMENT FACTORY CONTROLS SHALL MODULATE RELIEF FANS IN CONJUNCTION WITH OSA DAMPER POSITION.

OCCUPIED MODE - DISCHARGE TEMPERATURE CONTROL:

EQUIPMENT FACTORY CONTROLS SHALL CONTROL ECONOMIZER FUNCTION AND MECHANICAL COOLING/HEATING TO MAINTAIN DISCHARGE TEMPERATURE SETPOINT. IF SPACE SUPPLY FAN SPEED IS AT THE TEMPERATURE RESET HIGH LIMIT FOR A PERIOD GREATER THAN THE TEMPERATURE RESET TIME DELAY, THE DISCHARGE AIR TEMPERATURE SETPOINT SHALL BE LOWERED BY THE SUPPLY AIR RESET INCREMENT SET POINT. IF SUPPLY FAN SPEED IS AT OR BELOW THE TEMPERATURE RESET LOW LIMIT FOR A PERIOD GREATER THAN THE TEMPERATURE RESET TIME DELAY, DISCHARGE AIR TEMPERATURE SETPOINT SHALL BE INCREASED BY THE SUPPLY AIR RESET INCREMENT SET POINT. ONCE TEMPERATURE IS RESET, IT SHALL NOT RESET AGAIN UNTIL THE TEMPERATURE RESET TIME DELAY HAS BEEN

ACHIEVED.

ECONOMIZER/OUTSIDE AIR CONTROL:

EQUIPMENT FACTORY CONTROLS SHALL MODULATE OUTSIDE/RETURN AIR DAMPERS BETWEEN THE SCHEDULED MINIMUM OSA POSITION AND THE MIN OSA DCV RESET POSITION TO MAINTAIN CO2 SETPOINT, AND SHALL INCREASE OUTSIDE AIR FOR ECONOMIZER COOLING VIA DRY BULB TEMPERATURE CONTROL. CONTROL SHALL BE FULLY MODULATING. UPON DETECTION OF A CO2 SENSOR FAILURE, OUTSIDE AIR DAMPER POSITION SHALL BE SET TO THE MIN OSA DCV INCREASE POSITION, OR HIGHER AS INDICATED BY ECONOMIZER CONTROLS.

UNOCCUPIED MODE:

EQUIPMENT FACTORY CONTROLS SHALL START EQUIPMENT IN FULL RECIRCULATION MODE (UNLESS ECONOMIZER COOLING IS REQUIRED), AND MAINTAIN UNOCCUPIED SPACE TEMPERATURE SETPOINT.
