Description & Project Overview
As part of its ecological transition program, the territorial department, and more particularly the Cantonal Buildings Office (also referred to hereinafter as “OCBA”), is developing several operations to transform cantonal buildings. The CO Cayla project concerns the renovation of the roofs of buildings B and C (see plan – appendix 08) and the creation of photovoltaic installations on these roofs. The SIA 31 phase studies, carried out by the Client's agents (see chapter 3), focused on the structural feasibility, the condition of the roof complexes, the security of access, the photovoltaic potential and the connection possibilities.
Phase SIA 32 favored a lighter principle of intervention: removal of vegetation; retreading of the existing waterproofing; revegetation, adaptation/addition to safety equipment (lifelines, guardrails); installation of photovoltaic panels including adaptation of electrical installations and connection of buildings B and C. The desired tenderer is a consortium of construction companies capable of assuming a global offer and the complete execution of the works and services set out in these specifications and the tender documents. The market is not divided into lots and partial offers are not accepted. The work to be carried out on buildings B and C of the Cayla cycle (hereinafter also referred to as “the project” or “the contract”), which are the subject of this call for tenders, are as follows: scaffolding, site installations and collective protection;
- renovation of waterproofing and securing of roofs;
- electrical installations, metering, connection, lightning protection and ITTO controls;
- photovoltaic installations, monitoring, commissioning and maintenance;
- related works, fire protection, sanitation, repairs and cleaning;
- coordination of a work site in a school establishment
