Construction documents in Morocco: structural, services and detail drawings

The construction documents stage, called EXE in Morocco, produces the drawings the contractor actually builds from. The structural engineer issues the assumptions note, the calculation note with seismic verification under the RPS 2000 and the formwork and reinforcement drawings, approved by the inspection body when one is appointed. Services engineers draw plumbing, electricity, air conditioning and ventilation, consistent with the RTCM, the fire decree, the gas appliance regulation and the distributors' connection rules. The architect completes the detail book, the joinery schedule and a coordination drawing of all openings so that structure and networks do not clash on site.

Scope

This page covers the full set of construction drawings for a building: structural notes and drawings, building services drawings and power balance, external networks within the plot, architectural construction drawings, detail book, joinery schedule, coordination of openings and, where used, the digital model.

It follows the building permit and feeds the tender package; on many projects the drawings are completed in parallel with the consultation and finalised before the relevant works start. Site supervision, tests and acceptance of the works belong to the site and handover stages.

Who does what

PartyRole
Structural engineerProduces the assumptions and calculation notes and all formwork and reinforcement drawings, and answers the inspection body's comments.
Inspection body (if appointed)Gives its opinion on the structural notes and drawings before the works and later checks the hold points on site.
Building services engineerDraws plumbing, drainage, electricity, low current, air conditioning and ventilation, and calculates the power balance.
ArchitectDraws the architectural construction set and the detail book, schedules the joinery and leads the coordination of openings between trades.
Client (owner)Validates choices that affect cost or use, and ensures the consultants' contracts cover the full construction set.

Inspection milestones

  1. Structure designed and approved by the inspection body Specification (CPS) requirement
    Assumptions note, calculation note with seismic check, foundation, formwork and reinforcement drawings complete and approved by the inspection body when appointed; hold point before structural works.
    Standards to check at this milestone: NM 01.4.097
  2. Building services drawings Good practice
    Plumbing, drainage, electrical, air conditioning and ventilation drawings, power balance and external network drawings delivered and consistent with the architecture.
    Standards to check at this milestone: NM 06.6.071
  3. Architectural details and coordination of openings Specification (CPS) requirement
    Detail book, joinery schedule and coordination drawing of openings checked so that no pipe or duct crosses a beam or column without provision.

Common non-conformities and follow-up

FindingAction
A duct or drain crosses a beam on the coordination drawing with no opening provided.Reroute the network or have the structural engineer design and draw the opening before reinforcement is fixed.
Reinforcement drawings issued without the inspection body's opinion when one is appointed.Withhold the drawings from site until the opinion is received and its comments are resolved.
Electrical drawings ignore the distributor's requirements for the meter position.Obtain the distributor's conditions and correct the drawings before the service entry is built.
Waterproofing and parapet details missing from the detail book.Complete the details before the roof works are priced or started; leaks at upstands are among the most frequent defects.

Frequently asked questions

Who signs the structural drawings in Morocco?

The structural engineering consultant appointed by the owner. When an inspection body is appointed, its opinion on the notes and drawings is obtained before the works.

Must construction drawings be finished before the tender?

Ideally enough of them to measure the works reliably. Drawings completed later must stay within what the contract priced, or a variation is needed.

What is a coordination drawing of openings?

A single drawing that overlays structure and all networks to locate every opening needed in walls, beams and slabs, preventing improvised drilling on site.

Do the construction drawings need to mention NM standards?

It is good practice for schedules and notes to name the mandatory standards for steel, cables and pipes, so that site checks have a clear reference.

Is a digital model (BIM) required?

It is not required by Moroccan regulation. It helps coordination on complex projects when the client and consultants agree to use it.
