MCALL ENGINEERING SERVICES water Hasoorees—gpilonA distribution system may require piping modifications to allow for the initial well discharge to waste or to the reservoir and not to the distribution system. Pipeline Design Tetra Tech's previous experience will help the City to suocessfully address the key pipeline Issues including: agency requirements, utilities, traffic control, alignment selection, and construction phasing. Early on In the project, it will be important to meet with the City Public Works to define the following requirements: work hours; lane closures; storage of equipment; open cut verses boring of intersections; trench backfiil; and pavement restoration. Tetra Tech will perform our utility research Immediately upon Issuance of the Notice -to -Proceed. The USA markings for the geotechnical Investigation will also be used to verify the location of existing utilities. Any potholing services will be completed by use of the vacuum extraction method thereby minimizing pavement damage and traffic disruption, In addition, a field walk will be completed to look for evidence of infrastructure (e.g. valve cans, trench patch, vaults, etc,) as some utility owners do not belong to USA Dig Alert, and others respond with only partially complete Information. We have learned the Importance of taking extra steps to verify potential underground infrastructures. The proposed pipelines in the sample project are stated to be located within an arterial street. Therefore, traffic control will be a major :concern of the City. The traffic control requirements shall be determined with the objective of providing the Contractor with adequate room for safety as well as efficient operation while providing the least possible disruption to the traveling public. We believe traffic control is a Ivey design element and should be completed hand -in -hand with the design of the pipeline, Similar to SA-5 Vault Relocation and San Lorenzo gift Station projects, both have pipelines being constructed within Bristol Street, Tetra Tech will prepare the conceptual traffic control requirements, specifying the work area and proposed lane closures that are acceptable to the City, The contractor will be responsible for the actual preparation of the traffic control plans based on these requirements. It the proposed pipelines cross a signalized intersection, Tetra Tech will evaluate whether a bore and jack operation or open -put construction will be the most beneficial solution. Typically, Tetra Tech has been able to show that open -cut construction during limited work hours or during times of minimal traffic Is the better solution verses bore and jack operations due to the 24 hours, 7 day lane closures required for the pits. Project Management Over the years, Tetra Tech has established well defined, rigorous procedures for project management. These techniques have been developed and refined and have contributed to our success and reputation. The keys to our project management system are communications, project planning, monitoring, and quality assurance. The Tetra Tech team's goal is to keep the City staff "in the loop" from day one of the project, Communication tools include formal progress reports afforded through our project management system and an Informal give-and-take approach starting with Tom Epperson, our Project Manager, and extending to every member of the Tetra Tech team, At the project's outset, the chain of command and appropriate communication.methods will be agreed upon and can be as formal or as informal as the City desires, We will use the entire communication spectrum. We will conduct formal meetings with agenda and typewritten notes, and we will use informal meetings with notes to file, We also will have documentation of telephone communications, with notes to file or letters of understanding as appropriate follow-up.
