Home My WebLink About8/1/2001 - STAFF REPORTS (8) DATE: August 1, 2001 TO: City Council FROM: Director of Public Works/City Engineer CONSTRUCTION CHANGE ORDER NO. 1 TO E. L. YEAGER CONSTRUCTION COMPANY RECOMMENDATION: It is recommended that City Council approve Contract Change Order No. 1 to E. L. Yeager Construction Company, for an increase of $74,300.00, for a total contract amount of $300,075.00, for the Crossley Tract Street and Drainage Improvements, Phase 4, City Project No. 00-31. SUMMARY: Contract Change Order No. 1 will add installation of sewer laterals and sleeves for future gas service to each vacant lot located on Marguerite Street. BACKGROUND: On June 6, 2001, the City Council awarded E. L. Yeager Construction Company the contract for the Crossley Tract Street and Drainage Improvements, Phase 4, City Project 00-31. This project is the final phase of the Community Development Block Grant investments made to generally improve this low income neighborhood. Subsequent to award of this project, staff received numerous inquiries from potential home builders regarding the vacant lots within this neighborhood. Specifically, of the forty lots located on Marguerite Street,twenty-eight are vacant. Potentially, the completion of this project will stimulate development of the vacant lots. In that event, the newly constructed street would be trenched and excavated for sewer, water and gas service laterals for each vacant lot at the time of development. Staff has coordinated with Desert Water Agency and Southern California Gas Company to facilitate installation of service laterals prior to construction of the street improvements. In this way, all underground service laterals will be in place and no street cuts will be required as the vacant lots develop. This proposed change order covers the following items: Increase to Contract Items (New): Item A is proposed to be added to the contract to provide for the installation of four inch vitrified clay pipe (VCP) sewer laterals, and connections to the exist sewer main within Marguerite Street. Item B is proposed to be added to the contract to provide for compensation to the contractor for sheeting, shoring and bracing, or equivalent method, which is required by law for excavations exceeding four feet in depth. /A Construction Change Order No. 1 to E. L. Yeager Construction Company August 1, 2001 Page 2 Item C is proposed to be added to the contract to provide for the installation of one inch schedule 40 yellow polyethylene (PE) pipe for use as sleeves for future gas service laterals. Fifteen working days will be added to the contract to allow for the construction time required for the new contract items. As the sewer,water and gas service laterals are ultimately the responsibility of the owner(s) of the vacant lots, approval of this contract change order will temporarily subsidize those owners the cost for installing the laterals. However, staff intends to utilize the authority granted by Resolution 16031, adopted by the City Council on October 15, 1986, that allows the City to install off-site improvements that are the responsibility of a property owner in advance of developing their property, and to seek reimbursement from the property owner as a condition of development of the property at the time application for building permits is made. In this way, over time as the vacant lots develop the City will recover the costs associated with this change order. Sufficient funds are available in block grant account no. 137-4801-63503 (Street Improvements, Crossley Tract). Please note that all costs are being paid for by outside HUD block grant funds and no local general funds are required, and further, that these costs will be reimbursed as discussed above, and redistributed into the City's block grant account for future use by block grant projects.
