Built to spec
Built to your engineered drawings, survey, and the real site conditions, not a standard package forced to fit.
Harrowgate Group self-performs design-build concrete and civil construction across the GTA and Ontario for developers, industrial owners, municipalities, facility managers, and infrastructure owners. The field package is planned around survey and investigations, owner decisions, design reviews, permits and approvals, utility coordination, long-lead materials, enabling work, weather, testing, commissioning interfaces, and turnover documentation, with the work executed and managed by Harrowgate.

Design-build concrete and civil construction combines engineering coordination, constructability, pricing, permitting support, procurement, self-performed field work, testing, and turnover under an integrated delivery plan. Harrowgate Group self-performs and manages these packages across the GTA and Ontario for industrial, commercial, municipal, and heavy-civil projects with defined performance and schedule requirements.The package begins with owner requirements, survey, geotechnical data, existing utilities, operating constraints, and performance criteria.
Clean site work and a tidy finish, coordinated with your engineers, the other trades, and the surrounding site conditions, built to the engineered drawings and the applicable codes.
We establish the design basis, site constraints, authority interfaces, investigations, decision dates, and budget checkpoints, then assign responsibility for every drawing, calculation, permit input, and field deliverable. Long-lead reinforcing, precast, drainage structures, specialty embeds, process interfaces, and utility materials are released against coordinated drawings while enabling work advances under controlled packages.
The governing document set is the 2024 Ontario Building Code, CSA A23.1, A23.2 and A23.3, applicable OPSS and OPSD documents, municipal design criteria, environmental approvals, and the project-specific design basis. The design basis identifies the 2024 Ontario Building Code, CSA A23.1, A23.2 and A23.3 for concrete, applicable OPSS and OPSD requirements, and municipal criteria.
The price responds to design maturity, investigations, authority requirements, temporary works, quantities, soil and groundwater conditions, utility conflicts, concrete complexity, operating constraints, schedule compression, and procurement risk. Undefined owner criteria create redesign and scope gaps. We document capacity, service life, operations, finish, loading, access, and expansion requirements before the design advances.
The controlling schedule factors are survey and investigations, owner decisions, design reviews, permits and approvals, utility coordination, long-lead materials, enabling work, weather, testing, commissioning interfaces, and turnover documentation. Long-lead reinforcing, precast, drainage structures, specialty embeds, process interfaces, and utility materials are released against coordinated drawings while enabling work advances under controlled packages.
Yes. Design-build planning is especially useful on active sites because shutdowns, temporary services, emergency access, production routes, dust, vibration, and staged turnover can be designed into the construction sequence. Design packages issued without construction sequencing can create impossible access. Field leaders review excavation, forming, lifting, utilities, and restoration at each design milestone.
Quality is verified through design reviews, approved submittals, inspection and testing plans, survey checks, concrete and soil testing, utility tests, consultant field reviews, redline control, and area-by-area deficiency closure. The design basis identifies the 2024 Ontario Building Code, CSA A23.1, A23.2 and A23.3 for concrete, applicable OPSS and OPSD requirements, and municipal criteria.
Provide owner requirements, available drawings and surveys, geotechnical and environmental reports, utility records, performance criteria, authority comments, operating constraints, target budget, and required in-service date. Constructability reviews test excavation support, haul routes, crane access, pour sizes, forming cycles, utility conflicts, drainage, temporary works, winter conditions, and facility shutdowns before design is frozen.
