Services · Structural Shell
Structural shell isn't just a per-square-meter number.
Each option's scope is spelled out item by item — what Constrak includes, what the owner supplies, and what needs a site visit before it's confirmed.
- Labor-only shell
- Shell with materials
- Riyadh
01Two ways to build the shell
Labor-only or with materials: the difference is written down before pricing.
In both options Constrak executes on site; what changes is who supplies the materials, and how each scope item is classified.
Labor only
The owner buys materials per the agreed scope; Constrak handles labor, organization, and execution.
With materials
Constrak supplies materials and executes per clear specifications, quantities, and payment terms.

The owner buys materials per the agreed scope; Constrak handles labor, organization, and execution.

- Included by Constrak
- Supplied by owner
- Priced separately
- Dependent on drawings

03Scope matrix
Why does structural-shell scope differ from one quote to another?
Most late-stage structural-shell disputes come from an item that was never mentioned, not one that was disputed. The scope matrix below spells out every major item across both labor-only and with-materials before any commitment.
The owner buys materials per the agreed scope; Constrak handles labor, organization, and execution.

Before pouring
No structural element is poured before its formwork and reinforcement are checked against the approved drawings.
04Build sequence
The build sequence: from excavation to slab
The same stage order shown in the section above, with the mandatory quality hold points embedded at their real place in the sequence.
- 01
Excavation
Mandatory hold point
Testing
Concrete and soil testing where needed, specified in the quotation before pricing.
- 02
Foundations
- 03
Grade beams
Mandatory hold point
Before pouring
Formwork and reinforcement checked against approved drawings before any structural element is poured — this check repeats before every subsequent cast element (columns, beams, slabs).

Columns
- 05
Beams

During execution
Periodic checkpoints documented with photos, tied to the weekly progress report.
- 06
Roof slabs
Final inspection and the snag list happen at handover, beyond the structural-shell scope. Full detail on the Quality page

06Questions
Questions about the structural shell
What files are needed for a price quote?
The permit, approved drawings, and a bill of quantities if one exists, plus the land location and built-up area. We first confirm the files are complete, then determine whether the technical review needs a site visit before we issue a quote.
Who buys the materials?
It depends on the agreed scope: the owner buys under labor-only, Constrak supplies under with-materials. This is spelled out item by item in the quotation before signing.
How are payment milestones structured?
Each payment is tied to a defined execution stage and completion evidence agreed in the contract, not a calendar separate from actual progress. No payment is requested without verifiable work behind it.
Is there a site visit before pricing?
For projects that need field verification, yes. The site visit surfaces items the drawings alone don't show — like visible soil conditions or site access constraints — before a final quotation is issued.
