Summit Associates services also include the review and approval of construction plans, specifications, project schedule, and County standard plans and specifications to be thoroughly prepared for the work.
Our staff attends pre-construction meeting with County representatives, Contractor and other consultants as necessary to discuss and approved plans and applicable standards and specifications of the County. Our inspectors performed daily observations and prepared daily written reports, focusing on the quality of the work performed, staff levels and progress. We inspect all on-site and off-site Public Works and subdivision improvements on a daily basis to assure that all improvements to be constructed are as designed and are within tolerances.
We coordinated the construction of all County and other utilities to minimize interferences with subdivision improvements, reviewed and coordinated schedules, review materials, shop drawings, requests for information and performance test results, checked all certificates of compliance and evaluated the need for corrective action that are required. We monitored the contractor’s work and attempt to minimize the impacts upon public safety and convenience. Also verified the placement of warning signs and other safety devices to meet County standards and approved traffic control plans.
