1.1. PROJECT OVERVIEW:

This scope of works outlines the requirements for the complete replacement of the exis�ng waterproofing membrane and thermal insula�on on the flat roof of apartment building 01, located in Boulogne- Billancourt.

The three exis�ng buildings on the site were originally built in the mid-1950s, and with some par�al renova�ons of the roofs having already been carried out, the condi�on of the exis�ng roof finish has now reached a state in which it needs overhaul. The exis�ng area of each roo�op is approximately 645 sq.m., which a plant room of approximately 90sq.m.

The project involves the concep�on, removal of the exis�ng and replacement of the roof’s waterproofing and thermal complex up to and including the exis�ng perimeter where it meets the building facades.

A key requirement is also the provision and u�liza�on of a temporary external li� for material and worker access to the roof, to minimize disrup�on to building occupants and reducing internal access to a minimum, and if possible zero access to the interior.

An inves�ga�on of the exis�ng roof complex make-up was carried out in April 2025, from which the following photos were taken:
