Marie-Pierre ALIX structures the Construction practice through her expertise in Construction Law and Real Estate Law, acquired over the past 30 years by working alongside the sector’s iconic public and private project developers.
She assists Earth Avocats’s clients in the implementation of their real estate projects (CPI, VEFA, etc.) and is particularly involved in major litigation cases, including judicial expertise. Marie-Pierre ALIX is a frequent conference and training session speaker who also publishes numerous articles to advance legal doctrine. For more than ten years, she has provided training on “works reception and its consequences” with the French Public Works Monitor.
Marie-Pierre ALIX is co-head of the Construction practice alongside Stéphanie de LAROULLIERE.
They work with their team to help their clients deal with issues that may arise during a construction project, both in advisory and litigation matters.
They are involved from the beginning when the work contracts are written. They initiate preventive summary proceedings prior to the start of the works.
They then accompany their clients throughout the life of the construction site, dealing with all types of distress (disorder during construction, invoking insurance, abnormal neighborhood disturbances caused by the construction site, drawing up of statements of account, subcontracting, claims by companies, completion procedures, etc.).
They also play a role in extending the reception date for the lifting of the reception or delivery reserves, and of GPA, as well as in the implementation of the manufacturers’ legal guarantees. Finally, they intervene in litigation related to construction insurance (TRC, RC, RCD, damage insurance).
Aïcha BARRANI has been a valuable asset to the Construction practice since her arrival in January 2018.
She joined the firm after working for Atout France and specialized firms.
