Build, code, make it travel — wherever your project is decided.
The project is decided and funded. Three questions remain that nobody on the team can settle: which regime applies to the entity that is buying, what the margin becomes after withholding tax and currency exposure, and in which language this market will be addressed. That is when we get the call.
Three practices that travel with the same standard — for a manufacturer, a developer, a retail chain or a professional firm: from Morocco, where our tender files are being processed today, to the Gulf and West Africa. Every sentence on this page carries its proof, and every figure its date.

THEATRE 1 · GULF & MAGHREB
Where public procurement is counted in programmes
Decade-long equipment programmes, sovereign funds publishing their supplier channels, and local-content rules that decide who may bid.

THEATRE 2 · AFRICA
Where the lender writes the rules before the buyer
Major programmes are funded by international lenders, and it is their procedures — not local law alone — that shape how one bids.

Two theatres, on equal footing. Neither is the main one: they simply do not follow the same rules — which is why each has its own page.

REFERENCE · ONE FILE, END TO END
Design-build of a very high-end reception complex, in the restricted area of an international airport.
Morocco, 2026. Structural works and waterproofing package, seven-month contractual deadline, firm non-revisable price. The file arrived as a parent all-trades contract across three sites, inside which the real package — one site, two sub-lots — had to be isolated before writing a single line.
- 17documents read, from the specifications to the topographic plans
- 7months of contractual deadline, scheduled day by day
- ≈ 1,200 m²of net floor area, four quadrants around a circular patio
- 9questions put to the client before pricing
THE DELIVERABLE
The file's knowledge base
- Two contractual tiers untangled: the parent contract (all trades, three sites, eighteen months, revisable price) and the real package (structure + waterproofing, one site, seven months, firm price).
- Every fact tied to its document — specifications, administrative clauses, bill of quantities, descriptive estimate, architect's and structural drawings, fire and acoustic reports, network and level plans.
- What the file does not say is marked "to be confirmed" rather than assumed: the water table, the roof steelwork, the fire rating of the structure.
THE FACT THAT DRIVES IT
The specifications described an eighteen-month contract; the package to be priced lasted seven. Reading both tiers avoided scheduling — and paying for — a site installation two and a half times too long.
TECHNICAL OVERVIEW · WHAT THE FILE IMPOSED
The facts that make the price, as the documents state them. That reading — structure, quantities, requirements, site, contract — is what separates a priced bid from a guessed one.
The structure, as the drawings describe it
- Geometry
- Single storey with a high ceiling (about six metres), partial mezzanine on two levels, roof terrace; footprint of about 40 × 33 m, four quadrants around a circular patio; close to 1,200 m² gross floor area. No basement, no typical floor.
- Foundations
- Isolated footings of 1.80 to 2.80 m on 40 to 65 cm, perimeter strip footing, mass-concrete blocks and four localised 60 cm rafts under heavy zones; 10 cm blinding; allowable soil pressure of 1.8 bar.
- Seismic
- Zone 2, class III, site S2: tie beams from 30 × 40 to 30 × 65, sixty-diameter laps.
- Superstructure
- Columns-and-beams with 30 cm façade walls, 15 cm shear walls; columns from 30 × 40 to 30 × 100; beams up to 30 × 85 over an 8.30 m span; solid slabs of 20 to 27 cm; 13 cm slab on fill compacted to 96%.
- Hard points
- Two- and three-metre parapets in 25 cm walls, a cantilevered façade to prop for a long time, a fifteen-metre circular terrace, two offset floor levels, an expansion joint, a pit at −4.15 m and a services gallery at −3.00 m under ground that only goes down to −0.73 m elsewhere.
- ≈ 800 m³of structural concrete — 371 m³ of solid slabs, 263 m³ of walls, 82 m³ of beams, 47 m³ of columns
- ≈ 120 tof HA FE500 steel — 28.7 t in the substructure, 91.5 t in the superstructure
- 1,340 m²of two-layer waterproofing, 432 m of upstands, 160 m² of wet rooms
- ≈ 1,800 m²of insulated double partitions, imposed by the acoustics
- 6,854 m²of renders, inside and out
- 3,376 m²of stripping, 826 m³ of excavation, 872 m³ of backfill
What the documents require
- Concrete B10 to B30, waterproofed in the substructure, "highly detrimental" cracking class below ground; batching plant mandatory; steel and formwork inspected before every pour; compaction checked by an approved laboratory.
- Fair-faced concrete, sample approved by the architect on pain of redoing the work.
- SBS bitumen waterproofing under technical approval, flood tests of 72 then 24 hours, specific ten-year cover; spray insulation prohibited.
- Acoustics: façades above 35 dB on the runway side, internal insulation of 50 to 55 dB, double masonry partitions throughout, floating screed everywhere — 56 mm more on every raw floor —, flatness of 7 mm under a two-metre rule.
- Fire safety: high-risk rooms fire-rated one hour, shafts half an hour; no smoke extraction to reserve.
The interfaces where failures are born
- Structure ↔ waterproofing: parapet level, screed fall, upstands above the protection, drainage reservations — decided before the parapets are poured, not after.
- Screed ↔ floors: the acoustic report sets the slab levels; substrate moisture is measured before laying, the calendar is not enough.
- Structure ↔ services: shafts sealed before ducts, anti-vibration bases under roof equipment, an existing 600 mm collector to protect at the edge of the site.
What the site imposes
- Restricted area under access control: staff vetting within ten days, badges, imposed routes, permanent guarding, no accommodation on site, a single access.
- Safety stoppages imposed by the operator: they trigger amendments — a schedule lever to write into the programme, not a risk to endure.
- Sensitive networks not mapped under the footprint: to obtain before any excavation; co-activity with no claim possible, coordination borne by the package.
What the contract commits
- Seven months at a firm, non-revisable price: the material exposure on 120 tonnes of steel is priced and covered, not endured.
- Daily penalties with two contradictory caps between documents, and an ambiguous lump-sum clause — to be clarified before submission, otherwise provisioned at worst case.
- 3% performance bond, 10% retention per instalment, payment at 60 or 90 days depending on the document, joint-costs account kept by the package: the financing cost goes into overheads, with its date.

ARCHITECTURE & 3D
Six programmes, decided on image.
Villas, collective housing, a subdivision, a place of worship: for each, the same geometry rendered by day and by night, in base then validated variants — the client chooses on images, not on promises. Hover a card to switch to night.
150 affordable villas
Residential programme of 150 terraced villas on two and three levels, two façade treatments, roads and planted areas.
3D modelling of the programme, two façade variants, street and overall views, day and night versions — validated with the client on images, before any permit drawing.
183 affordable housing units
Collective housing on four levels around a courtyard, corner tower, ground-floor shops, parking at the heart of the block.
Aerial view, street-level views, detail of the corner tower, sky view of the site plan — the same geometry in day, night and texture versions, to settle materials and colours without waiting for the site.
78 high-end villas
Semi-detached villas on two levels, arcades and arched openings, aligned along a waterfront; forecourt, parking and gardens.
Aerial overall views by day and by night, main, rear and side façades, variants with garden and boundary wall — twenty views for a single programme, because a villa sells on every face.
Three private villas
Three single-family houses for private clients: two contemporary treatments, one in stone; exteriors and interiors.
Day and night façades, figures for scale, and the interiors — kitchens and living rooms in three wood tones — to choose on image what cannot be corrected afterwards.
Residential subdivision
Layout plan of a subdivision — plots, roads, green spaces, legend — and its five-level buildings seen from the street, by day, by night and at dusk.
From the layout plan to the mood image: the same project read by the developer, on the plan, and by the buyer, from the street.
Neighbourhood mosque
Minaret, prayer hall, crenellated enclosure and gate; planted forecourt.
Four viewpoints, in base then optimised versions, by day and by night — materials and lighting settled on image before the site opens.
