Soletanche Bachy Fondations Sp\u00e9ciales is building the foundations for Digital Realty MRS5 in Marseille!<\/h1><\/div>
<\/div>

After participating in the construction of the MRS4 data center foundations in 2021, Soletanche Bachy Fondations Sp\u00e9ciales is back on-site at the Grand Port Maritime de Marseille four years later to continue the adventure with the MRS5 project. The objective: to build the foundations for Digital Realty’s future data center in Marseille.<\/p>\n<\/div>

The MRS5 Project: Transforming a Historic Site into a Technological Showcase<\/strong><\/h2><\/div>

This project aims to transform a 1960s industrial brownfield into a cutting-edge digital infrastructure: a next-generation data center built on a one-hectare plot. Within this context, Soletanche Bachy Fondations Sp\u00e9ciales is bringing its expertise to bear in constructing the foundations for this future data center.<\/p>\n<\/div>

SBFS Expertise Tackling Major Technical Challenges<\/strong><\/h2><\/div>

Data center infrastructure presents considerable technical challenges: heavy equipment loads, strict stability requirements, and millimetric tolerances on foundations.
The Oligocene Stampian substratum in Marseille, known for its steep hardness, requires specific drilling techniques.
The precast column-beam structures can transmit loads of up to 700 tonnes, with strict embedding requirements and eccentricity tolerances\u2014particularly on low-cut-off level piles.
Thanks to its experience and mastery of the STARSOL\u00ae process, the teams developed an optimized design that ensures both stability and performance.<\/p>\n<\/div>

The specifications required the use of low-carbon concrete, with a minimum 29% reduction in CO\u2082 emissions compared to standard CEM I concrete.
Soletanche Bachy Fondations Sp\u00e9ciales exceeded this goal by proposing an innovative mix design that achieved a 50% reduction in CO\u2082 emissions, thanks to the support of the Soletanche Bachy materials laboratory.
Additionally, all equipment on-site operated using HVO biofuel, with a total consumption of 29,200 liters.<\/p>\n<\/div>
