The District’s business telecommunication network provides service for data, phones, cameras, and security systems.  The business network is accessible from water reclamation facilities, water production facilities and other remote facilities including the customer service call center.  As the District increases utilization of telecommunication services, network reliability and service redundancy has become a critical business requirement.


The District’s bandwidth needs and its reliance on network connectivity for the business network and security/access control systems has increased dramatically over the past ten years.  The District needs to improve system reliability, scalability, and capacity by utilizing a fully redundant telecommunication network architecture.


This proposed project will construct three communication towers at three tanks site across the District’s service area in order to provide an upgraded and secure communication network (Exhibit A).


On June 15, 2020, bids from two pre-qualified contractors were received under Specification No. 1398, Microwave Tower: Broderson, Hunter, and Sky Mesa Project.  One of the bids was deemed non-responsive and the other bid significantly exceeded the engineer’s estimate. The District elected to reject all bids received, revise the contract documents, and rebid the project.


On September 3, 2020, the District received bids under Specification No. 1389-REBID. As shown on the attached summary of bids (Exhibit B), Carbon Activated Corporation, of Compton, California, submitted the lowest responsive and responsible bid, in the amount of $556,765.  The engineer’s estimate for this project was $635,000.


The total project cost through administrative closeout is estimated at $763,000 per the attached project cost estimate (Exhibit C).
