Agenda Item #24
Bayside High School - Construction Management Services - HVAC - SALES SURTAX
Plant Operations and Maintenance identified that two of the three chillers at Bayside High School are failing. Bayside High School is scheduled in year 6 of the sales surtax program. A design services contract was executed with OCI and Associates under their continuing services contract for mechanical, electrical, plumbing and fire protection (MEP) services to redesign the central mechanical plant to increase thermal capacity storage, reduce energy consumption and improve operational reliability.
Bayside High School consumes the highest amount of energy of all of the District's high schools. During FY 2015-2016, Bayside used 24% more kWh per square foot than Viera High School, a similarly sized school with a similar layout. Some of the issues that are causing this anomaly are being corrected with the new project. The scope includes sealing some of the larger gaps in the building structure, modifying the return and exhaust air systems, modifying the building automation system and installing bipolar ionization in each air handling unit. These modifications have resulted in a net decrease in system load of over 300 tons of air conditioning, which is expected to reduce the electrical consumption by at least 30%. The estimated annual energy savings is at least $110,000.
The District issued Request for Proposals #17-P-049-DR for the project. Three proposals were received. All respondents were interviewed and the Selection Committee recommends that the contract be awarded to Doug Wilson Enterprises, Inc. Following the selection process, Doug Wilson Enterprises, Inc. submitted a Guaranteed Maximum Price (GMP) in the amount of $2,878,418.96 for construction management services, based on the design by OCI and Associates. Administration and permitting costs are estimated at $50,000.
The funding in the Sales Surtax Funded Detail Report (Attachment F) is not sufficient to fund the scope needed to address the numerous issues with the central mechanical plant. The Independent Citizens Oversight Committee (ICOC) has been advised of these issues and the need to invest contingency funds most recently at their October and December 2016 meetings. However, the project cost exceeds the contingency available and will require capital investment. Sales surtax contingency is already being used at Bayside High School for the design of the building envelope renewal for Buildings 6 and 7 as approved by the Board on January 24, 2017 and noted to the ICOC in December 2016.
The sales surtax facility renewal funding available is approximately $1,012,362.90. This is the full Attachment F allocation of $1,068,897.00 less spent and encumbered to date, net . The balance to fund the project is $1,916,056.09, which will be funded through capital. This project will conclude all of the facility renewal work at Bayside High School.
Board approval is required for purchase orders in excess of $50,000. Approval is requested as a consent agenda item in order to order the equipment immediately. Although summer 2017 construction is planned, the Plant Operations and Maintenance team is concerned about immediate failure.
Authorization to enter into a contract with Doug Wilson Enterprises, Inc. for construction management services at Bayside High School.
Approval of the Guaranteed Maximum Price (GMP) submitted by Doug Wilson Enterprises, Inc. in the amount not to exceed $2,878,418.96 of which $1,012,362.90 (up to the full balance available) will be funded by sales surtax with the remainder funded by capital (estimated $1,866,056.09) .
Approval of the administrative budget (through construction) including staff time, testing, permitting and inspection expenses in the amount of $50,000 to be funded by capital.
