Building trades

The building sector is an indisputable lever for any society development. It brings together trades that are as varied as they are diverse. From a contract signing to the finishing work, a building construction involves several more or less specialized actors. These craftsmen, technicians, engineers and workers, fascinating because of their skill, continually innovate in a construction field that continues to evolve at the rate of technological innovations. Spotlight on the building trades, often confused and misunderstood, sometimes unknown, but how fascinating!

Building trades related to project development and coordination

When we recall the construction trades, we often think of masonry, carpentry, painting and a few other popular skills. In fact, there are many other specialties that are used upstream of the «construction» phase of a construction project. These much more technical jobs often require a higher level of study. And the skills used make it possible to design, study, evaluate the project and organize the work.

Building engineer

A building engineer is an executive called upon at all steps of a construction project. Sometimes in the office and sometimes in the field, it is he who is in charge of the feasibility studies of the project. He takes note of the specifications and studies the various parameters of the project. He records topographic data, conducts geotechnical studies and analyzes the environmental impact of the project. Then he dimensions the project, determines the technical procedures to be used, draws up plans and figures the costs. He also plans the work and ensures that it is carried out on budget and on time. The building engineer can also be found in the administrative procedures for obtaining authorizations and certificates. In contact with all the trades involved in a construction project, he is the real conductor.


Building trades: Architect

An architect has technical and artistic skills that allow him to draw the plans of a construction. It takes into account the expectations and the budget of the owner (client), the standards in force as well as the technical constraints to represent the construction on paper. Also, he is called upon to follow the work progress to ensure that they are in accordance with the plans drawn up. But the architect may have to fully manage a project if he is the project manager. This is the reason why he also has managerial and financial skills.

Construction manager

The site manager organizes and supervises the teams in the field. He directs part or all of the work ensuring their proper execution. In collaboration with the team leaders, he distributes the tasks and reviews the work once completed. He has a fast pace of work and is generally a leader of men who knows how to motivate his troops. He works in synergy with the work supervisor who is his hierarchical superior and to whom he reports regularly. He is also delegated certain administrative tasks related to the management of personnel, invoices and purchase orders.

Work supervisor

On a project, the work supervisor is the person in charge of the construction site. He directs all activities on the site. We can say that it represents in the site what the building engineer represents for the project. He coordinates the human, material and financial resources on the site, supervises recruitments and the work and ensures that quality and deadlines are respected. Responsible for purchasing, he also ensures compliance with safety rules on the site. At the same time in relation with the engineers, architects, site managers, customer, suppliers and even the residents of the site, he is a fine technician who has a sense of responsibility and contact. On large construction sites, he works closely with the works director who is his direct supervisor.

Land surveyor

Using precision tools, the professional exercising this trade travels through a field to identify its physical and legal characteristics. Then, the measurements taken are translated into plans and maps. He has a sense of space and nothing escapes his watchful eye. Precise and meticulous, he sets the limits of the construction. He can also perform other functions according to his level of qualification (technician, expert, engineer).

Building technician

Alone or in a team, the building technician develops the construction project technically and financially. He draws up the detailed plans, calculates the costs, defines the quantities of materials and establishes estimates. He also participates in the development of the execution schedule and provides technical solutions as the project evolves.

Business manager

Prospecting the market, managing a portfolio of clients, drafting contracts, supporting clients in carrying out their projects are his main activities. He is the customer’s dedicated contact. He is good at listening and negotiating and liaises with the suppliers and service providers involved in the project. He studies the prices, buys the equipment, follows the evolution of the execution schedule and ensures that the budget is respected.

Building trades related to the work execution

In this category, the building trades encountered are much more manual. They are used for the realization of the shell of a building, as well as development and finishing work.


Building trades: Builder

It is arguably one of the most well-known trades in the construction industry. It is a pillar trade on a construction site. The builder creates the foundation for the building just after the preparation of the ground. He assembles walls and joists, installs partitions and prefabricated elements, prepares and applies mortar and plaster and lays slabs. His universe is made of bricks, concrete, plaster, resin and many other materials of which he has the secret. And he is in good physical condition, has a sense of balance and layout, and he is very rigorous in terms of safety rules.
