The SPA1 Tower #2 location will provide public safety radio communications for the geographic area the radio communication site serves and integrates to the Regional Wireless Cooperative (RWC). The SPA1 location will also incorporate other public safety communication needs for the City. Several elements contribute to the integration and implementation of the P25 Simulcast G subsite. A 180’ self-supporting tower to be erected along with construct of a 15’x30’x10’ site-built communications shelter upon City owned property which has an approximate lot size of 60’x135’. The City intends to initiate all civil work for the site and retain a CMAR (Construction Manager at Risk) to provide all elements of the desired radio communications site which meets City, RWC requirements as well as meeting manufacturer installation requirements. The site work will be part of the CMAR design and their scope not the City of Surprise. The expansion of the Simulcast G will address public safety communications needs for the geographic area as well as addressing Fire Hazard Zone deficiencies within the same geographic area. The site will be the Eleventh radio communications site added to Zone 5, Simulcast G. The site will host 700MHz equipment, Fire Hazard Zone VHF equipment, and City Municipal equipment (public safety). Selection of the CMAR will be critical for the project’s success and that selection will be required to have experience with radio communication sites, integration into the Regional Wireless Cooperative radio network, and managing sub-contractors such as Motorola or other wireless integrators. In addition to the construction of the communications tower and site shelter, electrical service considerations include commercial power connections to the nearest 3 phase transformer; backup generator, automatic transfer switch; DC rectifier; installation of a battery bank; and the usage of multiple voltage ranges. Physical security will also be incorporated into the design of the communications site and will include such items as lighting, fencing, gate, PACS systems, and video monitoring.
