Agenda Item #36
Oak Park Elementary School - Change Order #1 for Additional HVAC Services (SALES SURTAX)
The School Board approved a Guaranteed Maximum Price (GMP) contract with H.J. High Construction Company on January 20, 2015 under their Construction Management Continuing Services Contract for HVAC renewal services at Oak Park Elementary School. The scope of work, which preceded the sales surtax, included replacement of 26 fan coil units and 5 new outside air units, based on a design by TLC Engineering. The Board approved the GMP in an amount not to exceed $646,177.09 and a total project budget not to exceed $756,429.09.
The District then engaged TLC Engineering to design the remaining facility renewal items identified on the funded sales tax list (Attachment F) for Oak Park. Based on TLC's construction estimates and H.J. High's change order proposal, staff is recommending that the Board approve Change Order #1 with H.J. High which includes only the remaining mechanical system items for construction this summer. Their GMP proposal for this work is not to exceed $683,641.60, which is included in a net project budget increase of $749,601.60. The new total project budget is not to exceed $1,506,030.69. Change Order #1 includes an additional 16 days.
The initial budget and GMP were funded with budgeted Capital Funds. Change Order #1 and the associated project budget increase will be funded through the sales surtax. Attachment F identifies a total of $865,785 for the mechanical items. This is not enough to fund both the original project scope and the increased scope based on Attachment F.
Additionally, the TLC design included all other Attachment F facility renewal items such as electrical and sanitary systems. These are a lower priority than the HVAC renewal and are being deferred until later in the sales tax program because there is insufficient sales surtax funding for these items.
Upon completion of the project phases, staff will summarize costs in comparison to Attachment F and report to the ICOC. This may be a project where additional sales surtax resources above the amounts specified in Attachment F will be requested.
Board approval is required for a purchase order over $25,000. In order to expedite the work, approval is requested without prior information.
Approve the Oak Park Elementary School revised project budget for HVAC renewal in an amount not to exceed $1,506,030.69 requiring net additional funding in an amount not to exceed $749,601.60
Approve Change Order #1 with H.J. High Construction Company under their Continuing Services Construction Management Contract in an amount not to exceed $683,641.60, for a total GMP not to exceed $1,329,818.69, with 16 additional calendar days.
