Inspection and Testing
This area has several responsibilities that can be grouped into the following categories: construciton, specifications, permits, testing, bridges, and drainage.
Construction responsibilities include tracking pay items, keeping daily diaries, preparing progress payments, preparing contract modification orders (CMOs), facilitating communication between the contractor and the project engineer, scheduling other County personnel involved (testing, surveying, etc.), attending project meetings, and ensuring compliance to plans and specifications. They confirm that all safety requirements and traffic control plans are followed.
In addition, this group helps develop specifications applicable to County construction projects such as asphalt paving, concrete work, bridge projects, drainage construction, hot mix asphalt, soils, and other things. They review specifications and change or amend them as requested by the engineering staff. They also issue permits to work in the right-of-way and inspect the sites as needed to ensure proper construction techniques and traffic control plans are being followed and that safety requirements are met. The inspectors issue special transport (oversize and/or overweight) permits, check the proposed routes for posted structures, and may provide escort for especially large loads.
Inspection personnel perform materials testing on County construction projects. Testing includes concrete, hot mix asphalt, and soils. They ensure that submitted mix designs follow approved designs, and suggest methods to improve compaction of sub-grade and backfills when difficulties arise. Materials such as chips, anti-skid, gravel, crushed concrete and millings are tested on a yearly basis before the construction season begins for in-house projects. The group maintains a fully functional laboratory and keeps its nuclear license up to date.
Inspectors conduct bridge inspections of all in-service bridges on a two-year cycle, and maintain the bridge inventory as well as issue service requests for repairs. They suggest possible repairs and report deficiencies to engineering. They inspect these repairs once they are completed. The group meets with the state consultant on a two-year cycle to discuss the state of the County’s structures.
The inspectors also perform yearly inspections of ponds and channels that the County maintains, prepares inspection reports, and suggest repairs as needed. They ensure all erosion control measures are in place and functional.
Several members of this group have certifications from the Colorado Asphalt Pavement Association (CAPA) and the Federal Highway Administration (FHWA) in inspection of in-service bridges and contract administration, erosion control and survey internship from the state of Colorado, nuclear density testing from Troxler Company, concrete testing from the American Concrete Institue (ACI), traffic control technician, and are members of the American Public Works Association (APWA).
