Expertise 04 / Complex works and operations
Complex works
Live networks, deep trenches, large-diameter pipes, busy areas: worksites where method makes the difference.
Our approach
The tighter the constraints, the more preparation counts.
A sewer seven metres down beneath a shopping street. A two-metre-diameter pipe to be renewed without interrupting the network. An operation at the foot of a monument, under the eyes of residents and tourists. These are the worksites SA LA GARONNE is called in for.
Our added value lies in preparation: construction studies, precise phasing, suitable shoring, urban logistics, coordination with operators and city departments. On site, experienced crews and plant sized for these conditions.
Crew safety, continuity of service, schedule compliance: on a complex worksite, these three requirements are never negotiable.
Situations
What we know how to do.
The configurations our crews are specifically equipped and trained for.
Working on a network in operation without interrupting flow or distribution: pumping, bypass, section-by-section phasing.
Trenches 6 to 7 metres deep with suitable shoring, management of water ingress and securing of the surroundings.
Laying and renewal of pipes up to Ø 2000 mm: lifting, bedding, assembly and dedicated checks.
City centre, pedestrian zones, around public facilities: reduced footprint, fine phasing, resident information.
Worksites amid dense utility networks: locating, protection, diversions and coordination of all parties.
Night work, short phases, operations planned around events or operating constraints.
Method
Prepare, secure, execute, verify.
A single method applied to every complex worksite, whatever its size.
Constraint analysis, construction studies, detailed phasing, traffic management plan and safety plan.
Engineered shoring, signage, access and flow management, protection of neighbouring structures and crews.
Experienced crews and suitable plant: deep excavation, lifting, large-diameter laying, live networks.
Testing, inspections, controlled backfilling, like-for-like reinstatement and complete as-built documentation.
Resources
Crews and plant sized for the job.
35 employees, a dedicated plant fleet and 70 years of worksites across the Toulouse metropolitan area.
Technical data
Other expertise
Complete know-how across water networks.
