How we work

Design and construction under one roof

Structural design and site execution sit in the same company, so changes on the drawing and changes in the ground are resolved by the same team rather than between two contracts.

Works under traffic and in occupied buildings

Infrastructure works are staged with traffic management; refurbishment is sequenced so that tenants, staff or operations continue through the construction period.

Tender-grade documentation

Bills of quantities, construction programmes and cost reports are prepared to the standard public clients audit against, and the same documents are issued to private clients.

Ground conditions taken seriously

Earthworks, shoring and foundations are planned from the soil investigation, not from assumption, and the method statement is revised when the excavation says otherwise.

Handover you can file

Every project closes with as-built drawings, test records, material certificates and a defect list that is worked off rather than left open.

From enquiry to handover

  1. Enquiry and brief

    You describe the project, the site and the intended use. We confirm whether it falls within our scope and what information is still needed.

  2. Site review and feasibility

    We inspect the location, review existing drawings, surveys and ground data, and set out the constructible options with their consequences for programme and cost.

  3. Offer and contract

    You receive a written offer with a defined scope, bill of quantities and construction programme. Nothing starts before the scope is agreed in writing.

  4. Execution

    Site set-up, own crews and coordinated subcontractors work to the programme, with a named project lead, regular site meetings and documented progress.

  5. Handover and documentation

    Joint inspection, defect list worked off, as-built drawings and test records issued, and the warranty period begins on the agreed terms.

What clients say

★★★★★
Municipal drainage renewal through a village main street. The phasing was explained before works began and the street was never fully closed. Progress reports arrived every week without us asking.
Martin
★★★★★
Refurbishment of an office floor while the floors above stayed in use. Noisy work was kept to agreed windows and the defect list was closed out within the inspection period.
Elisabeth
★★★★☆
We commissioned the structural design and then the shell from the same team. Coordination questions that normally cost weeks were settled on site the same day.
