b. Work Coordination: All work shall be coordinated with the COR and local facility contacts.

c. An initial site visit is required for accurate bidding and system verification.

2. Pre-Installation:

a. The Contractor shall coordinate and conduct a kickoff meeting with the COR and IHS staff. The meeting shall compromise of:

i. Introductions between IHS and the Contractors team members. This will begin initial discussion on the needs, concerns, and scheduling of the replacement process.

ii. The Contractor shall participate in the meeting onsite with IHS staff. If necessary, the CO and/or COR may participate via teleconference rather than onsite.

b. Contractors will develop and present a Hydrostatic Test Plan, which will describe the test procedures in accordance to NFPA 13, a minimum of two (2) weeks prior to the Acceptance Test.

c. Provide a plan for conducting fire supply pipe and backflow preventer removal and installation activities within an occupied and operating health clinic. This plan will include methods to address the following:

i. Levels of construction noise

ii. Construction detritus and dust accumulation

d. Infection Control Risk Assessment (ICRA)

i. Weekly Construction and Infection Control Checklist shall be reviewed and evaluated in consultation with the Infection Control Officer.

ii. Activities that result in excessive dust accumulation within the health center, such as cutting and demolition, will require the Contractor to use approved methods to contain and minimize dust dispersion. Methods for dust control are listed in the attached Infection Control Construction Risk Assessment Approval Checklist and require strict adherence. Contractor methods will be evaluated on a weekly basis by the Infection Control Officer.

e. Interim Life Safety Measures Plan

i. The Contractor is responsible for notifying and gaining advance approval from the IHS Safety Officer for any modifications or disabling of life safety systems as necessary to complete this work. Examples include temporary modification of exit paths or temporarily disabling an alarm system.
