2. BCC Bathrooms Renovation

The Boncompagni Community Center (BCC) serves as a multifunctional hub hosting a wide range of activities, including meetings, private events, and summer camps for children, and various community programs. Its shared use with the Study Center further increases the daily occupancy and overall traffic within the facility.

Due to age and prolonged use, the existing restroom facilities are currently in poor condition. The primary goal of this project is the complete renovation of the first-floor restrooms, which will support the numerous activities taking place within the building.

The proposed design includes the creation of a new ADA-compliant restroom to ensure accessibility for individuals with disabilities, as well as a dedicated janitorial/storage room to improve maintenance operations and staff efficiency.

The Scope of Work (SOW) also includes the demolition of an existing restroom block located at the end of the corridor, resulting in an unused room that may be repurposed in future phases.

This Scope of Work (SOW) describes all labor, materials, and coordination required for the renovation of the bathroom facilities at the Boncompagni Community Center (BCC).

The project encompasses the following primary work areas:

Renovation of two (2) existing bathroom blocks — Women's Bathroom and Men's Bathroom.

3. MSB Bathrooms Renovation The Mel Sembler Building accommodates multiple office spaces, generating a high level of restroom usage throughout the day.

The purpose of this project is the renovation of the restroom facilities located adjacent to the twin elevator lobby, within the area identified as the “GSO Side.”

Currently, the corridor includes two separate restroom blocks — one designated for men and one for women — together with a small storage room (Housing). In order to improve circulation and accessibility to the restroom areas, the project proposes incorporating a portion of the existing storage space into the restroom layout, creating a more functional and comfortable entrance configuration for one of the two restroom blocks.

Additionally, the design includes the construction of a new partition wall behind the existing central door in order to permanently close its access while preserving the door itself in place, due to its historical significance.

Create an internal partition wall between the two restrooms subject to renovation, constructed using hollow/cellular masonry blocks with the following dimensions: Height: 25 cm, Width: 25 cm, Length: 25 cm. The wall shall be built using hollow clay blocks or autoclaved aerated concrete (AAC) blocks, laid in staggered horizontal courses, with bastard cement mortar dosed at 350 kg of Portland cement 32.5 R per cubic meter of screened sand (type M5 or M10 per UNI EN 998- 2), with the addition of natural hydraulic lime in a 1:1:6 ratio (cement : lime : sand), suitable for ensuring adequate workability, adhesion, and mechanical strength for use in humid environments such as restrooms. Mortar joint thickness shall be approximately 10 mm minimum, both horizontally and vertically. The new wall shall be bonded and tied into the existing perimeter masonry by means of vertical chases cut into the existing walls for toothed block insertion. The wall shall extend from the floor to the roof slab, with the upper head joint sealed using expansive cement mortar or high-density polyurethane foam, to ensure continuity and the absence of acoustic bridges.

Included in this line item is the supply and installation of smooth finish plaster on both faces of the wall, up to the level of the ceramic tile cladding, comprising the following layers:
