This document is a Supplemental Special Provisions document from ACHD (Ada County Highway District) for the Munger Rd Bridges 1005 and 2001 project, with Project Number 224008. The document provides detailed specifications for contractor-furnished construction surveying and staking, specifically outlining the requirements for surveying personnel, equipment, and methodologies for the project. The specifications cover calibration controls, surveyor qualifications, survey personnel requirements, equipment standards, utility staking, construction staking, and positional tolerances for various project elements.

The document specifies payment terms for the surveying work, which will be compensated through multiple line items: a lump sum for contractor-furnished construction surveying and staking (SP 20013), hourly rates for directed surveying office computations (SP 20013a), and hourly rates for directed surveying crew (SP 20013b). The contractor is responsible for providing qualified survey personnel experienced in urban roadway construction projects, furnishing necessary survey instruments, and maintaining precise survey tolerances as defined in the document. The surveyor must follow Idaho state regulations, maintain detailed documentation, and ensure accurate horizontal and vertical control points throughout the construction process.
