Supervision & Consultancy

Who checks whom on a project

Three layers of checking can exist on a project, and confusion between them causes disputes. The contractor supervises its own work and inspects it before asking anyone else to. The client's consultant, or the main contractor's engineer, inspects and accepts or rejects it. Where the specification requires, an independent laboratory or third party tests materials and systems. A contractor's supervision reduces rejections and surprises; it does not replace the consultant's acceptance. Some clients use a contractor's supervision function alongside their own consultant, others appoint a separate supervision firm and keep the contractor to self-inspection. Either can work if the boundary is written into the project documents; Main Contractor vs Subcontractor: What's the Difference? covers how it differs between main-contractor and subcontractor roles.

What each supervision function answers

The inspection request loop

1. 01

   Request

   The trade finishes its work and asks for inspection, with the drawings, the checklist and any test records attached. Asking before the work is complete wastes a visit.

2. 02

   Inspect

   The supervisor or consultant checks the work against the drawings, the specification and the approved samples, on site and before the next trade covers it. The same loop applies to structural, external, finishing and MEP work.

3. 03

   Record

   The result is written down as approved, approved with comments or rejected, with location and photographs. A verbal all-clear leaves nothing to rely on later.

4. 04

   Correct

   Rejected work is corrected and inspected again under the same request, so the record shows the fault and the fix.

5. 05

   Release

   Only then is the area released to the next trade. Without a recorded release, the next trade builds on work nobody has verified.

The handovers a programme depends on

Most delay sits at the handovers between packages. Log each one with a date, an owner and the record that proves it, so the programme shows what is actually ready rather than what is assumed. These are the five to log first:

• Structure released to the other trades, with the as-built survey (Structural Works).
• Roof treatment tested before cladding and paving go on around it (External & Facade Works).
• MEP first-fix tested before partitions and ceilings close (MEP Works).
• Wet-area waterproofing flood-tested before screed and tile go over it (Wet-Area Waterproofing).
• Finishes handed over area by area with the snag list closed (Architectural Finishing).

What good reporting looks like

A client should be able to open the project records at any time and see the current position. Expect:

• A programme tied to the main contractor's critical path, with a short look-ahead that changes when decisions change.
• A submittal log showing what is approved, pending and overdue.
• A technical query log with the date raised, who owes the answer and when it closed.
• An inspection register linking each hold point to its record.
• A short list of open non-conformances and safety observations, each with an owner.
• Photographs and progress by area, not a single overall progress figure.

Records are only worth having if they are kept current: a submittal log rebuilt at the end of a project records memory, not decisions.

What to write into the contract

Supervision is most useful when its terms are explicit before work starts:

• Named hold points for each trade, and who may release them.
• Review periods for submittals and technical queries, and what happens if an answer is late.
• How often reports and coordination meetings are issued, and who receives them.
• Which tests are witnessed and which are only documented.
• Who keeps the master programme and how changes to it are approved.
• The safety plan: who writes it, who checks site conditions and how observations are closed.
• Handover documentation, and who compiles it.

Saudi conditions that shape supervision

• Summer working restrictions. Authorities limit outdoor work during the hottest part of summer days, so external and structural activities need those hours built into the programme, with heat-stress precautions on site. Rules are updated, so confirm the current requirements when each project starts.
• Dust control in Riyadh. Larger sites face dust-control requirements, so suppression, covered loads and site watering belong in the safety plan from the start.
• Distance. Al Kharj, Huraymila and Muzahmia are a journey from a Jeddah-based team, so inspection requests, deliveries and query answers need planning around travel, and the inspection routine should not depend on a visit.
• Approvals and lead times. Stone, joinery and equipment often take a long time to deliver, and authority inspections can sit on the critical path, so approvals should be issued early and inspections shown in the programme.
