The month between signing a construction contract and the first real progress decides how the rest of the build behaves. Here is the sequence to insist on.
Mobilisation is the period between contract signature and the point where measurable work appears on your plot. It covers permits posted on site, temporary power and water, hoarding, access, welfare, survey setting out, the baseline programme, insurances and the first material orders. Owners abroad usually see this month as dead time, which is exactly why it is the month contractors use to absorb their own slippage.
Before stage one
Before anyone moves a vehicle onto the plot, the contract must already say who provides temporary services, who pays for connections, where site accommodation sits and what the contractor must submit before work counts as started. If those points are still open at signature, mobilisation becomes a negotiation instead of a task, and you pay for both.
- Signed contract with the mobilisation submittals listed as a condition of the first payment.
- Building permit issued through the municipal licensing route and available to display on site.
- Insurance certificates named correctly, including contractor all risks and third party cover.
- A single named point of contact on each side, with a deputy for when one of them travels.
- The plot boundary confirmed by a surveyor against the deed, not against the neighbouring fence.
Stage 1: Confirm the legal right to start
Check that the permit covers the design you are actually building, that any conditions attached to it are understood, and that approvals which sit outside the permit, such as civil defence requirements for the finished building, are already identified. Starting without this creates work that has to be undone.
- Deliverable: A one page register of every approval the project needs, with its current status.
- Owner: Owner or the appointed representative, with the design team.
- Approval gate: No excavation until the permit and its conditions are in the register.
Stage 2: Set out and record the plot as found
A licensed surveyor sets out the building position from the deed coordinates and records levels across the plot. Photograph and film the plot, the neighbouring walls and the access road before anything moves. This record is the only defence against later claims about damage that was already there.
- Deliverable: Setting out drawing, level survey and a dated photographic record of the plot as found.
- Owner: Surveyor, countersigned by the contractor.
- Approval gate: Setting out accepted in writing by both sides before foundations are marked.
Stage 3: Establish site access, hoarding and security
Decide where deliveries enter, where concrete trucks stand, where spoil leaves and how pedestrians pass. On an infill plot in a built up district this single decision governs how long every delivery takes for two years. Hoarding, signage and lighting follow from it.
- Deliverable: A site layout plan showing access, standing, storage, welfare and hoarding lines.
- Owner: Contractor, reviewed by the supervising engineer.
- Approval gate: Layout agreed before the first delivery is booked.
Stage 4: Connect temporary power, water and drainage
Temporary services are applied for early because they depend on third parties rather than on your contractor. Running a site on generators because nobody applied in time is a real and avoidable cost, and it also affects what plant can work at once.
- Deliverable: Applications lodged with reference numbers, and a written fallback if connection is late.
- Owner: Contractor, evidenced to the owner.
- Approval gate: Reference numbers shown before the mobilisation payment is certified.
Stage 5: Verify workforce compliance
Confirm that the people on your site are employed by the party you contracted with or by an approved subcontractor, that their status is documented, and that accommodation and transport meet the requirements that apply. Confirm current obligations with the relevant authority rather than accepting a verbal assurance.
- Deliverable: A workforce declaration naming each subcontractor and the trade it covers.
- Owner: Contractor, audited by the supervising engineer.
- Approval gate: No unapproved subcontractor working on the plot.
Stage 6: Fix the baseline programme and the reporting format
Require the programme, the cash flow forecast that follows from it, the procurement schedule for long lead items and a sample of the monthly report you will receive. Agreeing the report format now is far easier than asking for new information from a contractor who is already behind.
- Deliverable: Accepted baseline programme, procurement schedule and an agreed report template.
- Owner: Contractor, accepted by the owner in writing.
- Approval gate: Baseline accepted before the second valuation is paid.
Stage 7: Open the quality and document trail
Agree the inspection and test plan, the submittal list for materials that need approval, and where documents will live so that an owner in another country can open them. A shared folder with a fixed structure beats messages that scatter across phones.
- Deliverable: Inspection and test plan, submittal register and a shared document location.
- Owner: Supervising engineer with the contractor.
- Approval gate: First concrete pour only after the pour approval process is written down.
Handovers between stages
The weakest handover in mobilisation is between the designer and the builder. Drawings that were good enough for a permit are frequently not good enough to build from, and the gaps surface as questions in week three. The second weak handover is between whoever negotiated the contract and whoever now administers it, because conditions agreed in a meeting are worthless if the site team never sees them.
How you know it is finished
Mobilisation is complete when the permit register is closed, the plot record is filed, temporary services are connected or covered by a written fallback, the baseline programme is accepted, the workforce declaration is in place and the first month report has arrived in the format you asked for. Progress on the ground is the last sign, not the first.

Frequently Asked Questions
How long should site mobilisation take on a Saudi construction project?
It depends on the plot, the services involved and whether approvals were prepared during design. A tight urban plot with third party connections and restricted access takes longer to set up than an open plot on a served road. Rather than accepting a duration, ask which mobilisation items depend on outside parties, and require those applications to be lodged in the first week so the delay is visible early.
Should an owner pay a mobilisation advance to a contractor?
An advance is normal where the contractor must buy plant, set up the site and order long lead materials before earning anything. What protects you is not refusing it but conditioning it: pay against a guarantee, recover it across later valuations, and release it only once the mobilisation submittals are delivered. An advance paid against a promise rather than a document is the easiest money an owner ever loses.
What documents should a contractor hand over before starting work on site?
Ask for the insurance certificates, the accepted baseline programme, the procurement schedule for long lead items, the site layout plan, the inspection and test plan, the subcontractor list and the setting out drawing signed by both sides. Each of these is something you will need later in an argument, and each is much easier to obtain before the first payment than after it.
