  • Creation of detailed preliminary designs or compiling of the request for tenders on behalf of public and private sector Project Managers and Project Owners.
  • Design verification services on projects run by traditional Project Managers (external verification missions) or within a group of contractors (external verification missions).
  • Studies for detailed preliminary designs or designs, with variant solutions and advisory missions to contractors for purposes of technical and financial optimisation of projects, before the contractor submits its bids..
  • Design and construction support services within a consortium (architect, contractor, engineering firm) set up in order to participate in a design and construction competition..
