Stage Construction Clause Samples

Stage Construction. To ensure that traffic operations are not affected, detour and construction staging plans will be developed that will preserve or minimize the impact to the existing number of traffic lanes on I-680 in each direction throughout the construction period, except during critical short-term construction activities. Twenty-four-hour traffic counts will be performed to assess the impact of any needed lane closures. Preliminary information concerning lane closures will be used to develop feasible staging plans. Impacts to access for local business and private properties, will all be carefully considered in the staging plans. If nighttime closures are required, acceptable detours will need to be put in place. The details of how traffic will be handled during construction will be presented in the TMP. The lane closures will be done at night to keep traffic effects at a minimum. Public outreach will be performed ahead of time to ensure that closures will be announced in a timely manner. Temporary detours of existing interchange ramps may be necessary during construction. Most of the construction activity will be done behind temporary railing (type K) to keep lane closures and traffic disruption to a minimum. Project construction is based on the two major stages identified below. Several construction phases are associated with each construction stage. A conceptual stage construction plan has been developed (see Attachment I) to confirm Project constructability. The stage construction concept was presented to Caltrans Design Contra Costa on November 13, 2018, comments received have been incorporated. A construction sequence of the major construction activities of each stage is presented below. Refer to Attachment I for details. • Construct concrete barrier along I-680 median. • Construct overhead sign structure along I-680 median. • Construct CHP area along I-680 median. • Construct inside pavement widening for NB I-▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇. • Construct inside pavement widening for SB I-▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇. • Construct retaining wall No. 162 along I-680 median. • Construct retaining wall No. 213 along I-680 median. • Construct Midwest guardrail system along I-680 median. • Construct Maintenance Vehicle Pullout along SB I-680 right shoulder. • Construct concrete barrier along NB I-680 right shoulder. • Construct outside pavement widening along NB I-680 and retaining wall No. 180 and 424. • Construct outside pavement widening along SB I-680. • Construct retaining wall No. 153 along...
