In any construction project, success largely depends on the quality of the technical studies conducted beforehand. Too often underestimated or overlooked, this step is crucial to ensure project feasibility, safety, compliance with regulations, and cost optimization. As a project owner, understanding the importance of technical construction studies will help you make informed decisions and avoid costly mistakes.

What is a Technical Construction Study?

Technical construction studies encompass all analyses, calculations, and plans required to design and size a building or infrastructure. They take place in the early stages of the project—well before construction begins—and continue through to the preparation of the Tender Documents (DCE).

These studies typically include:

• Site and constraint analysis (topography, geotechnical, environmental)

• Structural calculations (reinforced concrete, steel, wood, etc.)

• Design of technical systems (plumbing, electricity, HVAC, fire protection)

• Detailed cost estimation

• Regulatory compliance (Moroccan and international standards)

Why Are They Essential?

1. Secure the project from the start
   A well-executed technical study confirms the project's technical and financial feasibility. It prevents surprises during construction, such as undersized foundations or poorly designed utility systems.

2. Ensure compliance with standards
   In Morocco, construction must comply with strict standards (RPS, RTCM, Eurocodes). The technical office ensures all designs meet these requirements, reducing risks of permit rejection or legal issues.

3. Optimize costs
   Technical studies allow for smart, cost-effective technical choices. This avoids budget overruns caused by design changes during construction.

4. Facilitate implementation
   The detailed plans and documentation make it easier to consult with contractors and ensure accurate execution aligned with the original design.

Key Phases of a Technical Construction Study

1. Feasibility Study
   This validates whether the project is viable from technical, legal, and financial perspectives. It includes site analysis, needs assessment, constraints, and a preliminary cost estimate.

2. Preliminary Design (APS)
   At this stage, the project begins to take shape with draft plans, initial technical concepts, legal constraints, and a global budget estimate.

3. Detailed Design (APD)
   This phase deepens previous analyses and produces complete technical documents: execution drawings, structural calculations, system designs, and an updated financial estimate.

4. Tender Documents (DCE)
   The DCE contains all administrative, technical, and financial documents needed to launch a call for tenders and select contractors.

What is the Project Owner’s Role?

As a project owner, your role is to clearly express your needs and goals. Most importantly, you must choose a reliable and experienced technical engineering firm. A good partner will guide you, anticipate risks, and support your decision-making at every step.

You must also request clear deliverables, monitor the progress of studies, and ensure that all technical recommendations are reflected in the tender process and the construction phase.

Conclusion: Technical Rigor Equals Peace of Mind

Technical construction studies are not mere formalities—they are the backbone of any building project. A thorough study leads to faster execution, better control, and results that meet expectations. To achieve this, it’s essential to surround yourself with qualified professionals who can turn your ideas into solid, sustainable, and effective technical solutions.
