ON -CALL ENGINEERING SERVICES distribution system may require piping modifications to allow for the Initial well discharge to waste of to the reservoir and not to the distribution system. Pipeline i0esign Tetra Techs previous experience will help the Pity to,suooessfully addressihe key pipallne Issues Including: agency requirements, utilities, traffic control, alignment selection, and construction phasing, Early on In the project, It will be Important to meet VAth the City Public Works to define the following requirements: work hours, lane closures, Storage. of equIpment; open put verses boring of Interseotlons; trench backfill; and pavement restoration, Tetra Tech will.perform our utility research Immediately upon Issuance of the Noticeto-Proceed. The USA moiddings lot the gootechnical Investigation will Also be used to verify Vie location of existing utilities. Any pothollng services will be completed by use of the vacuum extraction method thereby min . ItnIzing pavement daffls�oe and traffla.disruption. In adation, a field walk Will be completed to. look for evidence of Infrastructure (ip.g, valve -can$, trench patch, vaults, etc,) as sorrie utility owners do not belong to USA Dg Alert, and others respond . withr-Only Part I IQ1IV 'complete Information. We have learned%the importance of taking extra -steps to verity potential underground Iriffeattudturies, The proposed Pipelines In thaarkmp(a project are staJed to be locattod within on arterial Street. Therefo re, traffic control will be a major concern ofthe City. The traffic Control requirements shali be determined with the objeGtIvopt providing the Contractor with adequate room for safety as woll.as efficient operation while providing the least possible disruption to the traveling public. We believe traffic control is a key design eiement and should be completed hand-firi-hand with the design of the pipeline. Similar to $A-15 Vault Relocation and San Lorenzo Lift Station projects, both have pip,611nes, 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 piroparation of the tiiffjo control plans basied oil these re�Ulreiments. If the proposed pipelines cress a signalized Intersection, Tetra Tech will evaluate whether a bore and Jack Operation or open�cut construction wit be the most beneficial solution. Typically, Tetra Tech has been able to show that oponwcut construction during limited work hours top during times of minimal traffic Is the better solution verses bore and Jack operations due to the 4�4 hours., 7 day lane closures required for the plts. Proloot 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 pro 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 tearn, At the project's outset, the chain of command and appropriate communloation.rhathods 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 noted to file, We also will have documentation of telephone communications, with notes to f Ile or letters of understanding as appropriate follow-up.
