PURPOSE:
In order to utilize the Construction Manager at Risk (CMAR) project delivery method for the Townsend Water Treatment Facility Basin and Gravity Filter Improvements Project City Council approval for change order number 1 to contract 2013-133 is requested.
BACKGROUND:
On April 1, 2014 City Council approved engineering design contract 2013-133 in the amount of $545,000 with Hazen & Sawyer, PC for the Townsend Water Treatment Facility Basin and Gravity Filter Improvements Project. This project provides for the design of gravity filter improvements and basin rehabilitation / improvements at the Townsend Water Treatment Plant. The change order will allow the design engineer to prepare design submittals (mechanical, structural, electrical, architectural, and HVAC drawings and specifications) for CMAR use in constructability and value engineering (workshop) review. Approved value engineering recommendations will be incorporated into the final design.
On May 23, 2014 the Minority/Women Business Enterprise (M/WBE) Goal Setting Committee evaluated various construction program elements and approved a motion to utilize the CMAR project delivery program element. This best value contracting program element provides the opportunity for construction contractor input during the design, providing value engineering and construction insight on complex portions of the work, such as selective demolition and deep major piping tie-ins that will be required. It also provides the City with a Guaranteed Maximum Price (GMP) earlier in the project schedule as compared to Design-Bid-Build, allowing the opportunity to adjust the project scope prior to completion of design to meet budget constraints if necessary. After selecting the CMAR firm and completing the design phase, a future open-book GMP construction contract will be presented to Council for award in FY16 so the proposed improvements can be constructed.
For this change order, Hazen &Sawyer will continue to utilize the engineering services of S.L. King and Associates, Inc. a minority owned business (MBE). Eighteen percent of the change order amount will be directed to S.L. King and Associates, Inc. for their engineering services.
BUDGET IMPACT:
Funding in the amount of $134,500.00 is budgeted in the Water Resources Capital Improvements Fund account 515-7025-01.5410 (Professional Services).
RECOMMENDATION / ACTION REQUESTED:
The Water Resources Department recommends approval of change order number 1 for the Townsend Water Treatment Facility Basin and Gravity Filter Improvements Contract (Contract 2013-133) with Hazen & Sawyer, PC in the amount of $134,500.
