A successful project starts well before execution begins, and does not stop at the last finishing touch.
Privartys provides comprehensive support, from the design phase through to final delivery, integrating every stage within a controlled global contract logic.
This integrated approach, combined with close listening to the client, allows us to guarantee total coherence between your performance commitments and on-site reality.
Design and build is based on a comprehensive, demanding and collaborative approach: taking charge of the entire project through a design-build contract, without any break between the project management mission and the works phase, while fostering co-construction with the client.
We manage design studies, anticipate constraints relating to public procurement law, structure technical choices in consultation with economic operators, and then ensure contract execution in compliance with deadlines, costs and public law.
This continuity, enriched by a strong contractual commitment, guarantees better responsiveness, overall cost control and genuine clarity for the public client.
Our design-build approach is aimed at complex projects requiring a single point of contact, capable of combining client support, technical know-how and operational project delivery.
We work in particular on:
At Privartys, we believe that the success of a construction project depends as much on architectural quality as on rigour in contract execution.
By combining construction contracts and design, we build bespoke spaces with perfect continuity between preliminary design, BIM plans and the final result.
It is this unified vision, respecting the legal framework and thermal regulations, that allows us to deliver solid, refined projects aligned with your energy performance objectives.
Most popular questions
It is a single public contract that allows the client to simultaneously entrust the design of the work (studies) and the execution of works to a single group of economic operators.
This type of global contract derogates from the principle of separation between project management and the company, offering better synergy from the sketch phase onwards.
The use of a design-build contract is regulated by legislation.
It is often justified by technical reasons related to the complexity of the operation (e.g. energy efficiency, complex civil engineering) or by a commitment to quantifiable and measurable performance objectives during contract execution.
The award procedure can be a formalised procedure, a restricted call for tenders or a competitive dialogue depending on the thresholds.
We often respond in consortium with architects and design offices. The consultation file (DCE) specifies the subject matter of the contract and the award criteria.
Public procurement law requires, in principle, lot-based division.
However, the design-build contract constitutes a legal derogation allowing the commission to be globalised to guarantee energy performance or technical coherence of works delivery.
We ensure rigorous monitoring through to perfect completion and commissioning.
As contract holder, we are responsible for compliance with the specification, current thermal regulations and contractual clauses, thus minimising the risk of disputes before the administrative tribunal.
Absolutely. We support every public client (municipalities, urban communities, social housing organisations) in their works operations.
