VTrans Construction Inspection

 

On-call retainer contract with the Vermont Agency of Transportation for construction inspection services in support of agency resident engineer. Projects include:

Hyde Park Roundabout, Hyde Park. Construction inspection services for a new $1.5 million roundabout at the junctions of Routes 100 and 15. The pre-existing intersection was the location of numerous accidents and inadequate for the periodic high traffic volumes. The project was designed by VTrans. Working under VTrans’ Resident Engineer, D&K’s inspector provided full-time inspection services for the eight-month construction duration. The inspector performed fieldwork, observed and documented construction activities, kept detailed measurements and tracking of installed items and quantities, prepared daily reports, maintained a photographic record of the progress of construction, and participated in regularly scheduled construction status meetings. The inspector was instrumental in the coordination of traffic control, which was a critical component of this project. The new roundabout includes new subbase and base materials, drainage features, reinforced earth embankments, new granite curbing, bituminous concrete pavement, a textured and colored reinforced concrete truck apron, sign replacements and relocations, pavement markings, and landscaping.

“Big Dig”, Barre. D&K provided full-time construction inspection services over a 23-month period on the Barre City Improvements project, known as the “Big Dig”. This $16 million major road, utility, and streetscape reconstruction project extended 2,600 ft along Main Street through downtown Barre City and required significant detours and vehicular/pedestrian traffic management efforts. Project consisted of new road subbase, stormwater drainage, sewer mains and services, water mains and services, major intersection signalization, electrical service to new street lighting, concrete sidewalks, granite curbing, crosswalks, street signage, pavement markings, and related roadway items. Streetscape enhancements included new ornamental street lighting, granite bollards, street trees and landscaping, bike racks, benches, and decorative sidewalk treatments. The inspector was responsible for daily tracking of quantities, with a focus on drainage, roadway subbase, pavement, and pavement markings. D&K’s inspector worked 26 weeks of night work as the Contractor installed sewer, water, and drainage around the clock in order to meet contract completion milestones, and continued to provide services throughout the project closeout phase, which involved months of detailed quantity cross checking, tracking, and documentation.

Bridge Replacement VT-132, Thetford. D&K provided full-time construction inspection for a major bridge replacement project on Route 132, which consisted of removing the existing bridge, installing three 70-ft steel girder spans and a new concrete deck, and reconstructing portions of the existing piers and abutments. Unique bridge design included girders on elastomeric bearing pads, approach slabs pinned to the bridge deck, and expansion joints located at the outer edge of the approach slabs. Full-time inspection services including: assisting the resident with horizontal/vertical bridge layout; reviewing contractor’s safety protocols; materials sampling (rebar, nuts/bolts/washers, granular materials); onsite materials testing (concrete, asphalt); field-calibration of torque gun; use of fall protection equipment to inspect bolts, bearing pads, etc; verification of steel reinforcing layout; preparation of daily field reports; photo documentation of progress; quantities tracking using Sites Manager program; environmental monitoring associated with lead abatement and erosion control; finalizing the project by preparing final quantities including field-measurements, extensive calculations, and verifying/reconciling all quantities; and tracking field changes and transferring to plans.

Route 107 Field Office, Tropical Storm Irene Emergency Response. An inspector from D&K was assigned to the Route 107 field office that was established to support the $18 million reconstruction of Route 107; know as the “Last Mile”. D&K’s inspector was part of a five-member team that was responsible for reconciling Daily Work Reports (DWR) and reviewing invoices that had accumulated from the numerous contractors involved in this major project. Entered DWR’s into MATS (Materials Tracking System). Inspector provided periodic field services related to traffic control, reviewed granular materials for acceptance/rejection, evaluated damage to drainage structures, and made recommendations for rehabilitation/replacement. Inspector provided assistance in public relations with landowners impacted by the flood and identified creative and cost-effective repair solutions to drainage and drive entrances.
