Statement of Work

Heat Pump System Replacement for USGS Fredericksburg Magnetic Observatory

A. Background

The USGS Geomagnetism Program established its first observatory at Cheltenham, Maryland in 1900, when the Program was part of the Coast and Geodetic Survey. The USGS Fredericksburg Magnetic

Observatory was moved to Fredericksburg in 1956, a site that for many years served as the Program’s headquarters. Today, because it has produced high-quality data for so many years, Fredericksburg is one of the world’s most important observatories.

The USGS Fredericksburg Magnetic Observatory site consists of thirteen buildings on approximately 45 acres. The building of interest for this project is the Office Building (Building 8) (Fig. 1).

Building 8 is 1-story wood frame structure containing approximately 2,078 square feet of space. It is used as office space and to house computer servers and data communication equipment. Although USGS uses some space in this building, the main tenant is the Bureau of Indian Affairs. The building was constructed in 1955 and rehabilitated for its current purpose circa 2008.

One of the existing heat pump split systems that serve Building 8 needs to be replaced. The unit to be replaced serves the central/common area of Building 8.

B. Objective

The objective of this project is to replace the existing incorrectly functioning heat pump unit at the observatory Office Building (Bldg. 8) with a new heat pump system.

m. Check system to ensure it operates within manufacturer’s guidelines.

G. General Performance and Requirements

The contractor shall:

1. Furnish all labor, equipment, and supervision.

2. Confine operations to prevent or minimize damage to the natural surroundings, and plant material.

3. Protect existing structures and finishes, both interior and exterior, from damage during construction.

4. Coordinate with USGS regarding any required utility outages a minimum of 72 hours in advance.

5. Provide temporary weather protection to prevent damage to any interior areas.

6. Keep dust and dirt pollution to a minimum and ensure safety of persons in the work area.

8. Take all necessary precautions to prevent fires or injury to the public, building occupant(s), or damage to property of others during the performance of this contract.

9. The Contractor shall at all times keep the work area, including storage areas, free from accumulations of waste materials. Before completing the work, the Contractor shall remove from the work and premises any rubbish, tools, equipment, and materials that are not the property of the Government. Upon completing the work, the Contractor shall leave the work area in a clean, neat, and orderly condition satisfactory to the Facility Manager or Site

Representative. Train designated USGS personnel in adjustment, operation, maintenance, and safety requirements of the installed systems and other pertinent equipment.

10. All construction debris and rubbish shall be removed from the site daily and disposed of properly according to local, State, and federal guidelines.

11. The contractor shall be responsible for making all arrangements for the receipt of materials and supplies at the job site. Government personnel are not permitted to receive or sign for items delivered to the site.

Saturdays, Sundays, legal holidays, or other non-normal working hours, unless otherwise authorized by the Contracting Officer. Requests to work times other than normal hours shall be made in writing.

I. Special Site Considerations

The contractor shall not work or store equipment or materials within a 600’ radius of the two magnetic operations buildings on site. The two magnetic buildings are the Variations building and Absolutes building; see Fig 1.

Building 8 will be occupied by tenants during this project. The contractor shall coordinate their work schedule with the tenants and take special consideration in minimizing any affects this work may have on the tenants. The contractor shall immediately notify the CO or Facility Manager if the work will affect the habitability of the office.
