Road and other networks:
Definition and types of works

Road and other networks as a whole are essential to the smooth running of an urban area, guaranteeing safety, traffic flow, water management and access to public services. Construction and urban development projects must take account of the external works to meet the needs of residents and businesses.

What does road and other networks mean?


Roadworks are essential urban developments. They include roads, water supply, electricity and telecommunications networks. They play a vital role in ensuring connectivity, mobility and quality of life in urban areas.

Road and other networks also involve the construction and maintenance of rainwater and wastewater drainage networks. These networks make the land suitable for construction. Roadworks can also enhance urban or rural environments by burying networks, paving streets or repairing pavements. They depend on the evolution of planning and the needs of the population. They are therefore different depending on whether it is planned to build a residential area, a commercial area, an industrial area or a public space.

Doing the connection yourself?

On a smaller scale and for private purposes, if you are building a house, you can make your own connection if your land allows it. You can connect your plot to the water, telephone or gas network. That said, we strongly recommend that you call in a professional to avoid any problems!

What types of infrastructure are there?

Road and other networks works encompass several categories of structure, each playing a specific role in the creation and management of urban spaces.


Road works include the construction and development of roads, streets, pavements. They are essential for ensuring the smooth flow of traffic and pedestrians.

Example of roadworks: the pavement, traffic signals, traffic lights and safety devices are all integrated into these works to ensure the safety and efficiency of the road network.


Sewerage works concern the management of wastewater and rainwater. They include the installation of systems for collecting, treating and discharging wastewater, thereby helping to preserve the quality of the environment and public health. Sewerage systems are designed to collect wastewater from buildings and convey it to the appropriate treatment facilities.

Other networks

Other networks include crucial infrastructures such as drinking water, gas, electricity and telecommunications networks. Work on these networks involves the design, construction and maintenance of the systems that provide essential services to citizens. Other networks are buried underground and, while remaining unobtrusive, play an essential role in the running of the city.

Each of these categories of external works is essential to effective urban management. By combining road, sewerage and other network works, towns and cities are able to provide reliable, functional infrastructure that meets the needs of residents and supports urban growth.

French standards and regulations


Regulation NF P 03-001:

This standard defines the technical specifications for materials used in road and sewer connection work. It sets out the characteristics required for road surfaces, pipes, sewer and many other elements. For example, it specifies the mechanical properties of materials to ensure their durability in the face of traffic stresses and climatic variations.

Regulation NF P 98-331:

This standard concerns sewage works and sets out the requirements for their design, construction and inspection. It sets parameters for pipe diameters, minimum gradients, manholes and wastewater treatment systems. The aim of the standard is to ensure that wastewater systems are functional, durable and environmentally friendly. For pipes, the connection depth must be greater than 80 cm and they must be able to withstand a pressure greater than 4 bar. In the case of pavements, the connection pipe must be buried to a depth of 60 cm.

Regulation NF P 98-332:

This applies to roadworks and defines the rules for laying bituminous mixes. It specifies compaction methods, required thicknesses and asphalt mix characteristics. The aim of this standard is to guarantee the quality and durability of road surfaces, to ensure their resistance to traffic and bad weather.

Careers in road and other networks


Road and other networks mason:

Road and other networks works masons carry out a variety of tasks, such as installing sewerage, water distribution, gas, electricity and telecommunications networks, as well as creating paving stones or slabs, building small concrete elements and installing kerbs and gutters.


They are responsible for the initial earthworks, shaping the ground according to plans to create a solid base.

Geotechnical engineers:

These engineers study the characteristics of the soil and determine earthmoving methods to ensure the stability of future structures.

Machine operators:

They handle the earthmoving equipment to shape the ground in accordance with the plans, preparing the ground for the next stages.
