How we work

Four declared stages, from first visit to warranty

  1. Study & Quotation

    A site visit and drawing review, followed by a detailed bill of quantities with itemised lines — not a single opaque lump sum.

    Output: an itemised quotation

  2. Contract & Planning

    A contract that fixes specification and responsibility, attached to a schedule and a payment plan tied to defined progress milestones.

    Output: contract and schedule

  3. Execution & Supervision

    A resident engineer on site, documented material testing, and a weekly photo report showing actual progress against plan.

    Output: a weekly report

  4. Handover & Warranty

    A final snag list closed before handover, as-built drawings, and a written warranty on structural works and waterproofing.

    Output: as-builts + warranty

Questions about this service

What usually gets asked before contracting this scope

Yes. Our work includes infrastructure for the Al Yasmin subdivision: stormwater network excavation and installation, sub-base and asphalt, and sidewalks with surface drainage.

Reinstatement after excavation is a line item within the same scope of work, not a separate request after handover.
