Home Browse Search

street and bridge overcrossing. The signalized intersections will include intersection safety lighting on a separate circuit. The plans will conform to the requirements of Caltrans and the City. Any required lighting under the Alton Avenue overcrossing will conform to the latest IES and Caltrans guidelines for roadway lighting. Task 7.1.20 Revised Standard Plan Sheets Huitt-Zollars will include standard plan sheets required due to revisions. Task 7.1.21 Roadway Special Provisions Huitt-Zollars will prepare project specific Roadway Special Provisions in accordance with Caltrans' standards. The Roadway Special Provisions will bear the State of California Registered Professional Engineer registration seal with the signature, license number and registration certificate expiration date of the Engineer who prepared the Special Provisions or the Engineer under whose direction they were prepared. A list of contract items with item descriptions, item numbers, and units of pay, and item pay codes, but without quantities or estimated unit costs, will be included in the Special Provisions. Task 7.1.22 Roadway Engineer's Estimate Huitt-Zollars will prepare an Engineer's Estimate of construction costs, based on detailed quantity takeoffs and current unit prices. A reasonable upward adjustment will be applied to bid quantities that may vary during construction to allow for necessary design adjustments. The final estimate format will be the standard Caltrans estimating system. Quantities for contract items, including cost of lump sum items, will be substantiated by calculations. Quantity calculations will be neat and orderly and will show sketches, diagrams and dimensions necessary to allow them to be independently used by field engineers. Quantity calculations will be independently checked and substantiated with independent calculations. Task 7.1.23 Draft Hydrology/Drainage Report Huitt-Zollars will research existing improvement plans and drainage maps to obtain pertinent drainage information and plot said information on a tributary map. Huitt-Zollars will determine the limits and characteristics of watersheds, existing and future drainage facilities, and existing and future developments affecting the project limits. The information will be included in the Hydrology Study and considered in the design of drainage facilities. Design of drainage facilities will conform to current City and County standards and Caltrans Highway Design Manual and current Best Management Practices in conformance with the requirements of Caltrans and the Regional Water Quality Control Board. Task 7.1.24 Draft Storm Water Data Report Huitt-Zollars will update the PANED SWDR and ensure that the programmed project includes sufficient right-of- way and budget for storm water controls and identify project-specific permanent and temporary Best Management Practices (BMPs) that may be required to mitigate impacts. Drainage areas and total disturbed area will be defined, as will climatic conditions, existing drainage site conditions, site permeability, soil texture, existing vegetation and groundwater. Task 7.1.25 Transportation Management Plan In order to prevent unreasonable traffic delays resulting from construction activities, a Transportation Management Plan (TMP) will be prepared to maintain acceptable levels of service and safety during all work activities on the project area. TMP will identify traffic impacts for each stage of construction and provide mitigation measures and their associated costs. The TMP for this project will require effective application of traditional and innovative mitigation measures such as: • PubliclBusiness Information Campaign • Traveler Information Strategies • Incident Management • Construction Staging Strategies • Demand Management • Alternate Route Strategies • Contingency Plans 25D-60
