Balaruc les Bains (34) - Spa establishment
Project owner: COMMUNE DE BALARUC LES BAINS
Project manager: DHA (mandataire) / Marc Galligani (Architecte associé)

Description of project:

The new spa is located on the tip of the Balaruc-Les-Bains peninsula. With a total area of 16,800 m², it comprises two buildings with a maximum of 5 storeys and partial basement and a number of 2 m deep semi-in-ground swimming pools.

Given the very low bearing capacity of the surface soils and some substantial loading, the base solution led to suggesting auger-bored piles to support the structures and dewatering by drainage trenches to allow the earthworks to be carried out. As a variant, the contractor proposed replacing the piles for just the part built over a basement by a grid of rigid inclusions (CMC) associated with a raft.

Missions entrusted to FONDASOL:

G12 Pre-project geotechnical studies:

  • Provisions to consider with respect to the waters,
  • Soil Es modulus for sizing the slabs,
  • Design and construction recommendations for all the structures.

G2 project geotechnical studies – PRO and ACT phases:

  • Recommendations for the earthworks
  • Sizing for static and seismic stresses, and recommendations for constructing the foundations (piles),
  • Sizing parameters and recommendations for implementing the retaining structures,
  • Dewatering and estimation of the drainage flow rate,
  • Preparing the RFQ relating to the earthworks and foundations.

G4 execution study supervision comprising:

  • External control of the geotechnical design calculations and the plans drawn up by the contractors,
  • External control of the works and the documents relating to execution monitoring drawn up by the contractor.

In the context of these missions, FONDASOL carried out the geotechnical investigations comprising cored, pressiometric, and penetrometric boreholes down to a depth of 20 m, Lefranc permeability tests, laboratory tests (identification, study of treatment with lime, shear test, density, calcimetry).
