437-CSI-500 Site Prep for DR Rooms – Fargo 2-15-18

Scope of Work for Design-Build Prepare Digital Radiography Rooms for Fargo, ND Project Number 437-CSI-500

Contractor shall provide Design-Build services to renovate and site prepare 3 rooms for the installation of new Samsung Digital X-Ray Radiography Systems in Fargo, ND.

A. General Design Requirements:

1. The Contractor shall completely survey all existing spaces affected by the renovation. Survey shall include architectural, electrical, mechanical (including medical gases), structural, and low voltage systems. Contractor shall not rely on Samsung equipment drawings to provide existing conditions, but shall verify.

2. The Contractor shall meet with site staff to review details of the equipment drawings and to gather comments after each design submission (SD, DD, CD). The Contractor shall include Facilities Engineering, Biomedical Engineering, Imaging, and Samsung in all design meetings. The Contractor shall also plan for a kick-off meeting with Facilities Engineering, Biomed, Imaging, and Samsung to walk the site, pull as-built drawings, more specifically set design requirements and understand the full scope of the project requirements.

3. All equipment shall be removed and disposed of by the construction contractor except for the existing X-ray system that will be removed by Samsung. The VA will not retain any equipment and it shall not be “abandoned in place.”

4. New and modified building automation controls shall be included to ensure all systems are operational.

5. Environmental conditions shall be maintained to other spaces.

6. Phased installation shall be required. The phasing shall be clearly depicted in both the 010000 specification section and the drawing set SOW Appendix 1.

7. The Contractor shall include radiation shielding calculations, design, and modifications, as needed. The Contractor shall consult with a registered radiation physicist to ensure room design meets requirement for specified equipment. Registered radiation physicist shall provide calculations and certification of architectural documents.

8. Fargo has a contracted radiation physicist that may be able to provide shielding design for that site. It is anticipated that the Contractor would hire the physicist outside of the VA contract for lead shielding design work. SOW Appendix 2 provides a list of required information to complete the shielding analysis and design.

9. The current shielding report (dated 6-19-17) for rooms 1B-35 and 1B-37 is SOW Appendix 3.

10. The X-ray system has been purchased by the VA. The Contractor shall coordinate all architectural, electrical, HVAC and structural changes with Samsung. Samsung drawings shall be “For Reference Only” and all construction requirements shall be clearly shown in the CD set.

11. Design documents shall clearly show all demo, existing, re-located, and new raceways, wireways, and cabling to/from equipment, lights, medical gases, monitors, sprinkler heads/distribution lines, smoke detectors, electrical outlets, patient lifts, HVAC grilles, speakers, etc.
