The term VRD means Roads and Miscellaneous Network. It is written in the plural, “VRD”. By this term, we mean the construction of access roads, the implementation of water, electricity and telecommunications networks.

VRDs also concern the construction and maintenance of rainwater or wastewater drainage networks. These networks allow a piece of land to receive a construction.

These works also allow the beautification of an urban or rural environment during burial of networks, paving of streets or repair of sidewalks.

They depend on the planned layout and the needs of the population. Thus, they are different depending on whether one plans to build a subdivision, a commercial area, an industrial area or a public space.

The point in this tip.


The works below are carried out as part of VRD work. They constitute essential stages in the construction of a construction.


This is the essential step which will make it possible to prepare the land on which the construction of a residential, industrial, commercial building or a civil engineering structure (bridges, road …) is planned.

The company, which is in charge of the earthworks, carries out: excavations, cuttings, embankments, talutages and stripping.


Theroadworks are to achieve taxiways and parking areas:

  • roads, paths, pavements, footpaths, car parks allow access or parking near the buildings.
  • These works are essential for the movement of populations.


This term designates the sewage and sewage disposal networks, which will then be directed to a treatment plant to be treated and avoid any environmental risk of pollution:

  • This sanitation can be collective or autonomous in the case of sparsely urbanized areas.
  • Wastewater (EV) is waste that contains feces or urine.
  • Wastewater (EU) refers to household or industrial waste in liquid form, water containing detergents for example.
  • A sanitation network is also used to recover rainwater, which is generally transferred to the natural environment.

Various networks

This term includes:

  • drinking water supply;
  • the electrical distribution network;
  • the gas distribution network;
  • telecommunications;
  • more generally, everything that corresponds to the specific needs of the populations.

Ancillary works

In the VRDs, there are other works, which can be designated as ancillary works:

  • Thus certain masonry works like retaining walls, low walls are carried out within the framework of VRD works.
  • The retaining walls are earth retaining structures, in the case of an embankment for example.


‘s work is subject to regulations and standards:

  • The regulations stem from laws, decrees or decrees which deal with health or safety for the user.
  • This is the case with earthquake-resistant building regulations, the objective of which is to protect people and human life.
  • For VRD work, environmental protection laws or the water law are applicable depending on the work undertaken.

Legal bases of standardization in Morocco

  • Dahir n ° 1.70.157 of July 30, 1970 relating to industrial standardization with a view to seeking quality and improving productivity, modified in 1993
  • Decree n ° 2.70.314 of October 8 1970 fixing the composition and the attributions of the organizations of the industrial standardization
  • Decree n ° 2.93.530 of September 20, 1993 relating to the mark and the certificate of conformity to the Moroccan standards

Bodies of the standardization

  • Interministerial Superior Council of Quality and Productivity ( CSIQP)
  • Technical Standardization Committees (CTNs)
  • Moroccan Industrial Standardization Service (SNIMA)

Interministerial Superior Council for Quality and Productivity (CSIQP) Supervision

  • Prime Minister
  • Composition:

      –  Representatives of ministerial departments

     –   SNIMA (Rapporteur)

  • Missions:

       –   Establish the standardization strategy within the framework of economic policy

       –   Give an opinion on the Moroccan standards projects developed by the CTNs

Technical standards committees (CTNs)

  • Supervision: Minister responsible for the standardized product
  • Composition:

        Interested ministerial departments

        Representatives of the semi-public sector

        Professional organizations in the private sector



        Consumer associations

        Any personality or technician whose assistance will appear useful

  • Missions:

        Establishment of standardization work programs

        Study and drafting of Moroccan standards projects

        Launch of PNMs in public inquiry

        Finalization of PNMs at the end of the public inquiry

        Technical studies on standardization

Moroccan Industrial Standardization Service (SNIMA)

  • Supervision: Ministry of Industry
  • Responsibilities:

        Transmission to the TNC secretariats of the directives established by the CSIQP

        Centralization and presentation for advice to the CSIQP of PNMs

        Codification, printing and dissemination of approved Moroccan standards

        Representation of Morocco to foreign and international standardization bodies

Priorities in the development of Moroccan standards

 Standards explicitly requested by economic operators

  • Standards relating to health and safety
  • Standards facilitating the application of bilateral and multilateral free trade agreements
  • Standards necessary for certification

Standards relating to private markets also apply. They essentially relate to construction rules such as:

  • The sizing or justification of the works;
  • The constructive provisions.

In summary, the VRD designate all the works of pipes, evacuation, development and circulation:

  • Being around constructions or works;
  • Allowing to develop a building plot.
