HXL

The Process

Four stages. Fixed on price. Fixed on programme.

From first conversation to final snag, HXL runs every residential construction project through the same four-stage process. Each stage has a defined output, a named deliverable, and a fixed commercial position.

Stage 01

Concept & Feasibility

We engage with the client and appointed architect. Drawings are reviewed, feasibility assessed, cost plan issued.

  • ●Review of architect's RIBA Stage 2/3 drawings for buildability
  • ●Site feasibility assessment. Access, party wall implications, services
  • ●Preliminary cost plan against tender pack
  • ●Outline programme with critical-path milestones
  • ●Risk register covering planning, structural, heritage and discovery risks

Output

Cost plan, outline programme, risk register

Typical Duration

2 to 4 weeks

Proposal & Contract

Fixed-price proposal issued. Planning, Building Regs and CDM coordination agreed. JCT contract signed. Programme locked.
