DESCRIPTION
On December 1, 2020, the Board of County Commissioner entered into Master Services Agreement 2020-052 with Miller Construction, LLC to provide CMAR services when the cost of the construction is under $7.5 million.
The CMAR procurement method is used to hire a construction contractor during the design process so they can work with the design engineering firm when design plans are about 30% complete. The CMAR process is done in two phases. Phase one consists of the construction contractor working with the engineering firm and County staff to finish the design of the project. Once designed, the construction contractor will bid the work on behalf of the County. The bidding results are then brought before the Board for approval in the form of a GMP Addendum. The GMP Addendum is a Guaranteed Maximum Price (GMP) the CMAR will charge to construct the project. The GMP also includes the number of days to complete the project as well as a project schedule.
On July 16, 2025, the County authorized Miller to provide pre-construction services for a new Polk County Sheriff’s Office evidence storage facility in the amount of $50,424.66. Pre-construction services are now complete, and Miller has provided the attached GMP Addendum to construct the project in the amount of $888,245.70. In accordance with Resolution 13-066, $25,000.00 is included in the GMP total for allowance work.
The project consists of a 1.7 acre secure fenced, compound with a 60’X100’ pole barn to be located next to the new fire rescue training center located on Vaughn Road, Winter Haven. This new facility will be replacing the current evidence compound located in the evidence storage yard at the Sheriff’s fleet campus on Winter Lake Road, Lakeland.
The total contract time for construction is 140 calendar days. In accordance with Resolution 13-066, 21 calendar days have been added for allowance time.
