Scope

Understanding sequential pit underpinning

Where sequential pit underpinning is needed in Ajax by Harrowgate Group

Where sequential pit underpinning is needed in Ajax

In Ajax, sequential pit underpinning is typically needed for occupied and load-bearing structures. The recurring drivers are underpinning under a building that has to stay standing and in use, each Ajax project is scoped to its own situation rather than a standard package.

The Ajax market for sequential pit underpinning by Harrowgate Group

The Ajax market for sequential pit underpinning

In Ajax (Durham Region), sequential pit underpinning demand is driven mainly by automotive and parts manufacturing, logistics and distribution, food processing, and institutional. Ajax's Bayly and Salem industrial corridors feeding the 401 anchor a strong automotive, logistics, and food-processing construction market. Demand centres on industrial slabs, truck courts, servicing, and loading-dock work.

The work concentrates around the Clements and Bayly industrial corridor, Salem Road business park, and the 401 employment lands. Clients such as manufacturers, distributors, healthcare, and the Town of Ajax drive much of the Ajax work, and no two projects carry the same scope or ground.

The professionals your project needs, coordinated

Harrowgate Group treats coordination as part of the build. On an Ajax sequential pit underpinning project, that means working from the engineers' and architects' drawings, looping in geotechnical and civil consultants where the ground demands it, and coordinating with city planners and inspectors, so the Ajax project is built to the approved design and passes the inspections that matter.
