City of La Porte Fairmont Park Lift Station Attachment A Scope and Budget of Engineering Services Description of Project and Budget The project is to replace the existing four self-prime wastewater pumps with submersible pumps. The site presently consists of three circular wet wells. The following are project objectives on which the scope of work is based. Lift Station Capacity: Capacity is currently 1,100 gpm. The existing power feed and standby generator are to be retained, and the force main is to be re-used. This power and force main limitations are note expected to allow for an increase in capacity. Wet Well: The re-use of the existing wet wells or construction of a new wet well has not be determined. The scope of services to be provided are for Preliminary Design Phase and Final Design. The total budget for all services is estimated at $171,100 (a level of effort is enclosed). The Initial Authorization for Preliminary Design Services is $22,200. A subsequent authorization for an amount not to exceed $148,900, for the Final Design and Subconsultant services will be provided once the scope of work and associated level of effort is better defined. Initial Authorization The scope being authorized at this time includes Preliminary Design as outlined below. Preliminary Design This phase will identify options and recommendations with consideration of constructability and costs while meeting the objectives. A brief description of the work and objectives of the tasks are as follows: 1. Information Collection and Evaluation: Readily available information (force main properties, existing structure dimensions, pump discharge conditions) and/or assumptions from the City will be gathered to establish a preliminary technical evaluation of major design factors (pump curve sensitivity, preliminary pump selection, pump layout requirements, and pump horsepower requirements) and options (primarily new wet well versus re-use of existing wet well) and pump limitations based on the existing force main and generator. 2. Preliminary Report: A letter report will provide a summary of the options explored, and outline maintenance and operation items for discussion. A meeting will be held with key City staff to review the findings, address City questions and reach a consensus for direction. A total of six weeks, after authorization to proceed, will be required to submit the preliminary report for review. Future Authorization Engineer will develop a level of effort based on the scope of work identified as a result of the Preliminary Design. The general scope for final design will be in two stages described as follows. 1 of 3
