Service overview

Built around the actual property—not a generic package.

Alteration work connects new construction to an existing building, so information, sequencing and interfaces matter. We review the design status, approvals, access and existing conditions before defining a delivery scope and project-specific programme.

A typical scope may include

Connected work, defined in writing.

  • Pre-construction information review
  • Site logistics and access planning
  • Coordination with appointed designers and specialists
  • Structural and building work coordination
  • Weathering and existing-building interfaces
  • Interior completion and finishing
  • Programme, decisions and variation records
  • Practical completion and handover review

Project route

Pre-start

Scope, logistics, responsibilities, programme and quotation are agreed.

03

Construction

04

Completion

Finishes, documents and outstanding agreed items are reviewed at handover.
