Item 4HCITY OF SOUTH LAKE MEMORANDUM (April 15, 2014) To: Shana Yelverton, City Manager From: Robert H. Price, P.E., Director of Public Works Subject: Approve Change Order No. 1 with Durable Specialties, Inc. for the Illuminated Street Name Sign and Battery Back-up project to include the construction of the traffic signal at N. Carroll Avenue and Federal Way in the amount of $257,410. Action Requested: Approve Change Order No. 1 with Durable Specialties, Inc. for the Illuminated Street Name Sign and Battery Back-up project to include the construction of the traffic signal at N. Carroll Avenue and Federal Way in the amount of $257,410. Background Information: The purpose of this item is to approve Change Order No. 1 to the Illuminated Street Name Sign and Battery Back-up Unit Installation project (ILSN) to include illuminated street name signs for the Watermere/Jellico intersection with Southlake Boulevard and the installation of a traffic signal at the intersection of N. Carroll Avenue and Federal Way. City Council awarded the ILSN construction contract to Durable Specialties, Inc. on February 4, 2014. The signs are currently being manufactured. Installation will begin upon delivery of the signs. TxDOT construction of the Watermere/Jellico at Southlake Boulevard traffic signal and battery back-up began the week of April 7, 2014. TxDOT's construction contract did not include line items for the illuminated street name sign. This change order will allow for the installation of the ILSN concurrently with the remainder of the Southlake Boulevard corridor. The design of the Traffic Signal Installation at N. Carroll Avenue and Federal Way is complete and right of way has been confirmed for the right turn lane of westbound Federal Way to northbound Carroll Avenue. The right turn lane and 8-foot sidewalk will be constructed by th Public Works Street Department prior to installation of the traffic signal. Manufacturing time of the signal poles is eighteen to twenty weeks. In order to install the signal prior to the 2014 "Home for the Holidays" event, this change order with Durable Specialties, Inc. will expedite the order and manufacturing of the traffic signal poles and mast arms. The City Attorney's office has reviewed the request to change order greater than 25% of the original contract and have offered an opinion that it is acceptable in this case as it is "necessary to preserve or protect the public health or safety of the municipality's residents." Financial Considerations: The Traffic Signal Installation at N. Carroll Avenue and Federal Way project is a City Council approved CIP project funded in FY13 and FY14 from the Red Light Camera Fund. Funding for this project is available in project account 00008 and the approved budget is $315,000 for engineering and construction. The illuminated street name sign and battery back-up change order line items for the Traffic Signal Installation Southlake Boulevard and Watermere Drive/Jellico Circle W. project will be paid for out of project's FY13 City Council approved CIP project account 00009. Strategic Link: The installation of Illuminated Street Name Signs and Battery Back- up Systems and the Traffic Signal Installation N. Carroll Avenue and Federal Way project link to the city's strategy map relative to focus areas of Infrastructure and Mobility. The project will serve our customers by achieving the highest standards of safety and security. It provides travel convenience within the City and region. The specific corporate objectives that are met by this construction project are to invest to provide and maintain high quality public assets. Citizen Input/ Board Review: N/A Legal Review: The City Attorney has issued an opinion on the legality of this change order. Alternatives: The Council may approve the change order or deny it.
