Foundation construction: Architects and engineers begin to place foundations on the land, which are important supports for bridge or tunnel structures.
Construction of the structure: Once the foundation is in place, the construction of the structure of the bridge or tunnel can begin. This requires the use of concrete, steel and other materials, according to the design drawings to build.
Road construction: If it is a bridge, it is necessary to carry out road construction work connected with the bridge after the construction is completed; If it is a tunnel, you need to connect the ground to the tunnel.
Improvement of facilities: After the construction of the main structure, it is necessary to install auxiliary facilities, such as lighting, drainage system, ventilation system, etc.
Completion acceptance: After completion of construction, acceptance work is required to ensure that the bridge or tunnel being constructed meets the code and design requirements.
