STATEMENT OF WORK

HVAC Automat ion Controls

Marine Operations Center - Atlantic (MOC-A) Norfolk, Virginia

BACKGROUND

The Marine Operations Center - Atlantic (MOC-A), residing at 439 West York St, Norfolk, VA is owned by the National Oceanic and Atmospheric Administration (NOAA) and is comprised of two buildings.

The primary purpose of the facility is to provide personnel and logistics support to sixteen ships and more than 500 wage mariners. NOAA’s “research and survey ships comprise the largest fleet of federal research ships in the nation. Ranging from large oceanographic research vessels capable of exploring the world’s deepest ocean, to smaller ships responsible for charting the shallow bays and inlets of the United States, the fleet supports a wide range of marine activities including fisheries research, nautical charting, and ocean and climate studies. “ www.omao.noaa.gov

STATEMENT OF WORK

This request is for the replacement and upgrade to the existing Building Automation System (BAS) for MOC-A. The current BAS is a proprietary Java Based Controls System (JACE). NOAA prefers a non-proprietary replacement. For the purposes of this contract, NOAA is focused on heating and air conditioning equipment. A properly configured BAS senses air flow, temperatures and controls the operation of the chiller, fans, pumps, louvers and other HVAC components in response to both preset instructions, occupied/unoccupied conditions and outside air temperatures. This request is for a BAS and associated equipment necessary to properly control the heating, ventilation and air conditioning (HVAC) system throughout MOC-A’s Buildings 1 and 2. Currently there is a separate smaller BAS for building 2 and NOAA seeks a solution to combine both buildings into one system for centralized control and system management.

The Marine Center’s HVAC controls need to be replaced by a new BAS meeting the following requirements with an emphasis on non-proprietary technology to ensure ease of monitoring, maintenance, expansion and system updates. The below requirements shall not limit the vendor’s responsibility to provide a comprehensive solution that will meet the objective of this project. The period of performance will end September 15, 2017.

The successful offeror shall meet the following requirements:

1. The product will provide NOAA with the ability to control the internal office space climate of both building’s 1 and 2 to within OSHA recommended limits of 68-76F with a humidity of 20-60%. Set points for each zone will be able to be changed and adjusted from the controls program by the facilities manager.

2. The system will be off the shelf compatible with the existing heating and air conditioning equipment including split units, roof top units, thermostats, air handlers, hot water boiler systems, radiators, air pressure regulators, water pumps, valves, Variable Valve Volume boxes (VAVs) and the fire alarm system. The existing wall mounted radiators are to be included in this project either as an independent system or centrally controlled by the BAS.

3. The unit will connect, control and monitor new and existing equipment. The preferred option will be BACnet compatible because of its open source format and prevalence throughout the industry. Currently the system is primarily LONworks and moving to a single non-proprietary configuration ensures NOAA’s ability to maintain, trouble shoot, update, replace or add additional equipment.

i. The system will be non-proprietary so that a properly trained or certified technician can interface, download and update or modify software to the controls.

ii. The unit will not require special interface drivers or software to access, monitor and control equipment.

iii. Will be an open standard protocol and any licensed features will be licensed to the National Oceanic and Atmospheric Administration.

4. Throughout the facility, there are multiple wall mounted radiators that are still functional but are not regulated by the JACE or wall mounted thermostats. The adjacent thermostats are either not functional or do not control temperature valves in the units. If a BACnet solution to integrate the existing wall mounted radiators into the BAS is not available, the vendor will provide NOAA with the best alternative to ensure functionality and adjustment for proper workplace climate control.

i. The vendor proposed solution will complement the ventilation system and a properly configured BAS will use less energy to maintain a temperature in these zones rather than overrunning equipment or competing to control the climate in the zoned space.

ii. The primary goal is to reduce unnecessary wear and tear on equipment and increase the serviceable life of HVAC equipment, maintain habitability and reduce energy consumption.

5. The controls will have safety features and alarms programmed into the package to prevent over running and burning out of equipment due to low pressure, temperature or electrical and current issues external to the component.

a. The BAS computer itself will have an integrated Uninterruptible Power Supply (UPS) to condition power and keep the unit online during a power outage.

b. The unit will be able to monitor temperatures which ensure each Roof Top Unit (RTU), split system and chiller/boiler pumps will not overrun themselves in the event of a low pressure or high temperature condition.

c. Include relative alarms to notify the facilities manager of an event where a piece of equipment is no longer working and or needs service.

6. Program the system for occupied and unoccupied requirements.

a. Collaborate with NOAA to develop the best plan and ensure onsite facilities management can adjust as needed.

7. Integrate all heating and air conditioning equipment in both buildings. This includes recently installed or existing equipment that was never integrated into the JACE or BAS in Building 2. The following are examples however it is incumbent on the contractor to do a thorough inspection of the latest building drawings and perform a site visit to become familiar with the facility prior to bidding on this project. (This requirement excludes the mini split units in the downstairs offices spaces of building’s 1 and 2)

a. A 15 ton RTU on the roof of Building 2

b. A split system mounted on the roof of building 2 for the server room on the second floor

c. Four split systems for building 2, first and second floors

d. A boiler for building 2, associated valves, plumbing and hot water coils in the duct work or AHU’s.

e. A boiler in building 1, associated valves, plumbing and hot water coils in the

AHU’s, wall mounted radiators, and ceiling mounted radiators in the warehouse

i. Ceiling mounted heating coils in the warehouse (6 each)

f. A 60 ton Trane Air Cooled Chiller for building 1

g. 2 RTU’s on the west wing of Building 1

h. An Air Handling Unit (AHU) above the warehouse conference room

i. VAV’s throughout the duct work in both buildings.

i. Integrate existing VAV’s and associated thermostats located throughout the duct work to provide the best solution for balancing the ventilation needs of each zoned space.

1. Add additional VAV’s as needed to meet the OSHA recommended habitability requirement previously mentioned.

2. Install bypass or air pressure relief duct work for inline VAV’s or as needed with other equipment.

8. As needed, add additional thermostats to provide necessary data points for the BAS to better manage each of the zones.

i. A robust wireless solution will be considered on a case by case basis as long as it meets the DOC and NOAA IT Security requirements.

9. As needed, add control valves and or feedback loops in the hot and chill water plumbing to better manage the delivery to AHU’s, radiators and other existing equipment throughout the facility.

10. The system shall be web-enabled and accessible from almost any PC or Mac based systems through standard web browsers such as Internet Explorer, Google Chrome or Safari.

a. Internet Protocol or IP based interface

b. Able to isolate access and monitor over the existing NOAA Network per DOC IT protocol.

c. Must be able to clearly identify failure codes related to HVAC equipment. This ensures the user understands the nature of component failure resulting in the timeliness of repair and or adjustment to set points of equipment without the assistance from a contractor.

11. Connect both buildings through wired or wireless connection.

a. Preferred option will be robust and secure meeting DOC and NOAA IT security requirements.

12. Install variable frequency drives for fan motors to reduce energy consumption.
