The installation shall also comply with all applicable rules and regulations of local and state laws and ordinances. 1.03 RESPONSIBILITY A. Working hours shall be scheduled with the General Contractor (GC) and/or construction manager (CM). The GC or CM is responsible for coordinating all phases of construction with the PROJECT COORDINATOR, school’s principal, and DP. Advise of all meetings, work schedules, shipping/receiving dates, etc. B. It is the electrical CONTRACTOR’S responsibility to notify the PROJECT COORDINATOR and DP when pre-purchased equipment is being delivered. A representative of the Polk County School Board must be notified and have the option to be present to inspect the equipment CONTRACTOR’S. It is the CONTRACTOR’S responsibility to secure and protect any new equipment once delivered to his/her office or project site. C. It is the CONTRACTOR’S responsibility to schedule and perform all construction work such that the security of the building is maintained 100% of the time throughout the construction period. Contractor shall coordinate with GC or CM and shall follow all the PCSB DIVISION 16 Ӏ SECTION 16010 16010 – 1 of 10 POLK COUNTY SCHOOL BOARD Issue Date: 6.09.2014 DESIGN AND CONSTRUCTION STANDARDS Revision Date: These Standards are for guidance only.
