Road and Highway Construction

We establish survey, traffic control, utility locates, environmental limits, erosion controls, temporary drainage, removals, and access for emergency, local, commercial, and construction traffic. Earth cuts and fills proceed to profile with benching, moisture conditioning, undercut, stabilization, and compaction directed by geotechnical conditions. Ditches, culverts, sewers, and subdrains advance with grading.

The governing document set is applicable OPSS and OPSD documents, road-authority standards, CAN/CSA S6 where bridge elements are included, CSA A23.1 and A23.2 for specified concrete work, environmental approvals, and the traffic-control plan. Subgrade type, moisture, lift thickness, density, proof rolling, frost treatment, and geotextile or stabilization requirements follow the geotechnical design and road authority criteria.

The price responds to road length and width, traffic stages, excavation, unsuitable soil, rock, drainage, utilities, granular depth, asphalt quantity, concrete features, structures, haul distance, night work, testing, and restoration. Traffic on incomplete layers causes rutting and aggregate segregation. Staging plans define construction routes, maintenance, cleaning, load limits, and repair responsibility before surfacing.

The controlling schedule factors are permits, utility relocations, traffic staging, earthworks weather, drainage completion, subgrade acceptance, material supply, concrete cure, asphalt temperature and plant availability, markings, and road-authority inspections. We establish survey, traffic control, utility locates, environmental limits, erosion controls, temporary drainage, removals, and access for emergency, local, commercial, and construction traffic.

Yes. Lane-by-lane and intersection staging, temporary pavement, flagging or signals, signed detours, business access, emergency routes, and night or off-peak work keep required movements functioning. Building over wet or pumping subgrade traps a future failure beneath expensive pavement. We drain, proof roll, undercut or stabilize, and obtain geotechnical acceptance before granular placement.

We track survey, earthwork quantities, subgrade acceptance, density and gradation tests, pipe and structure checks, concrete tests, asphalt tickets, temperatures and density, smoothness, barrier installation, markings, and deficiencies. Subgrade type, moisture, lift thickness, density, proof rolling, frost treatment, and geotextile or stabilization requirements follow the geotechnical design and road authority criteria.

Provide road, grading, drainage, utility, traffic, structural, and landscape drawings, geotechnical report, OPSS schedule, quantities, staging requirements, authority permits, access obligations, and completion milestones. Earth cuts and fills proceed to profile with benching, moisture conditioning, undercut, stabilization, and compaction directed by geotechnical conditions. Ditches, culverts, sewers, and subdrains advance with grading.
