General_Note_-_Supplemental_Special_Provisions.pdf

These Supplemental Special Provisions detail surveying and construction staking requirements for the Munger Rd Bridges 1005 and 2001 project (Project No. 224008) for ACHD (Ada County Highway District). The document specifies comprehensive requirements for the contractor's surveyor, including qualifications, equipment, and responsibilities for construction surveying. Key requirements include calibrating and localizing control points, providing accurate field measurements, staking right-of-way and utility limits, and maintaining precise horizontal and vertical tolerances according to Idaho standards.

The document outlines specific payment terms for surveying services, which will be compensated through multiple mechanisms: a lump sum for contractor-furnished construction surveying and staking, hourly rates for directed surveying office computations, and hourly rates for directed surveying crew work. The contractor is responsible for all survey-related expenses, including monument removal and resetting, with specific requirements for documentation, workmanship, and compliance with Idaho Code. The project emphasizes the use of professional land surveyors (PLS) licensed in Idaho and mandates precise documentation and reporting of survey work.
