Agenda Item #23
Westside Elementary School - HVAC Construction Management Services - SALES SURTAX
Plant Operations and Maintenance has identified that the chiller is failing. The chiller was installed in 1997 and is beyond its life cycle. In addition, there have been several leaks in the chilled water piping system, which is highly disruptive. Westside Elementary is scheduled in year 5 of the sales surtax plan; however, the failing chiller and chilled water piping system failures warrants more immediate attention. The Independent Citizens Oversight Committee was advised of this issue at their August and October 2015 meetings.
The District contracted with OCI Associates, Inc. for design under their continuing services contract for mechanical, electrical, plumbing and fire protection (MEP) services. The scope of work to address the failures encompasses almost all of the facility renewal scope in the sales surtax funded detail report (Attachment F), with the exception of the relocatable covered walkways.
The design includes implementing bipolar ionization which results in an estimated annual energy savings of $60,000. The initial cost of bipolar ionization is roughly $65,000 which is offset by the estimated savings of $80,000 due to reducing the chiller size by 90 tons.
Based on the OCI design, Doug Wilson Enterprises, Inc. submitted a Guaranteed Maximum Price (GMP) under their continuing contract for construction management services in an amount not to exceed $1,404,715.68. Administration and permitting costs are estimated at $65,000.
The sales surtax funding for this project is not sufficient to accomplish the scope of work required. Any scope reduction would either leave failed or failing components or would be an incomplete system. The differential investment needed is $433,044.60. There is insufficient facility renewal sales surtax contingency and there are many other demands on this resource. In this case, staff is recommending that the difference be funded with capital because it is such a critical need. A similar situation exists at Bayside High School and the GMP will be presented to the Board as soon as the competitive proposal process is complete (planned February 28, 2017).
Board approval is required for purchase orders exceeding $50,000. Approval is requested as a consent agenda item so that equipment can be ordered in preparation for summer 2017 construction.
Approve the total project construction budget in an amount not to exceed $1,469,715.68 of which up to $433,044.60 is funded through capital.
Approve the Guaranteed Maximum Price submitted by Doug Wilson Enterprises, Inc., under their continuing contract for construction management services in the amount not to exceed $1,404,715.68.
