Passive Fire Protection Systems at Baheya Hospital

Atlantis Contracting successfully completed the supply and installation of comprehensive passive fire protection systems for Baheya Hospital in Sheikh Zayed City, Egypt — executed for ECS Construction in 2021. The scope encompassed the full range of Tremco TREMstop® firestop solutions applied across all MEP penetrations throughout the hospital facility, including cable trays, conduits, cable bundles, metallic and plastic pipes, HVAC service penetrations, and service risers. The works were executed to the highest standards demanded by a critical healthcare environment — protecting patients, medical staff, and essential hospital infrastructure while ensuring full compliance with international passive fire protection standards and healthcare fire safety regulations.

Project Overview

Baheya Hospital — Passive Fire Protection Systems

Client:ECS Construction.

Location:Sheikh Zayed City, Egypt.

Contractor:Atlantis Contracting.

Scope:Supply & Installation of Comprehensive Passive Fire Protection Systems for Healthcare Facility.

Main Systems:TREMstop® IA+ | TREMstop® Acrylic | TREMstop® Mortar | TREMstop® Wrap Strips | TREMstop® Coating | Smoke & Acoustic Barriers.

Standards:International Passive Fire Protection Standards | Healthcare Fire Safety Regulations.

Site Conditions Upon Arrival

Upon mobilization to the Baheya Hospital site, the Atlantis team conducted a full survey of all MEP penetration locations across the facility. The following conditions were documented:

•A substantial number of MEP penetrations through fire-rated walls, floors, and partitions had been installed by other trades without any firestop treatment — representing critical life-safety gaps in a healthcare occupancy environment.

•Hospital service infrastructure was highly dense — multiple cable trays, pipe bundles, HVAC ducts, and utility services concentrated in service corridors, risers, and plant rooms — creating complex, high-density penetration configurations.

•Plastic and combustible pipe penetrations were present throughout the facility, particularly in plumbing and HVAC zones, requiring intumescent wrap strip treatment to restore fire ratings.

•Service risers and utility shafts connecting multiple floors were open and unsealed, presenting significant vertical fire and smoke spread risk through the building.

•Healthcare construction environment imposed strict infection control, noise management, and patient area access protocols that constrained working hours, material handling, and dust generation throughout the works.

Site Challenges & Atlantis Solutions

Challenge 1: Critical Healthcare Environment — Infection Control & Patient Safety

Baheya Hospital is a specialist cancer treatment facility — placing the highest possible life-safety and infection control demands on any contractor working within its premises. All firestop works had to be executed without generating hazardous dust, fumes, or vibration that could compromise patient areas, sterile zones, or active clinical environments. 

Solution: Atlantis implemented a healthcare-specific works methodology — using low-odour, water-based TREMstop® products wherever possible to minimize chemical exposure. Work zones were isolated with temporary dust and fume barriers. All works in proximity to patient areas were restricted to approved access windows and coordinated with hospital operations management. Materials were pre-staged in designated secure areas to minimize movement through clinical zones.

Challenge 2: High-Density & Complex Service Penetration Configurations

Hospital MEP infrastructure is among the most complex of any building type — with high concentrations of critical services (medical gases, electrical, data, HVAC, plumbing) passing through fire-rated assemblies in close proximity. Many penetrations contained multiple service types in a single opening, requiring compound firestop detailing and multiple TREMstop® products applied within the same penetration. 

Solution: Each complex penetration was individually assessed and a bespoke firestop detail prepared — combining TREMstop® IA+ for cable and conduit elements, Wrap Strips for any combustible pipe services within the same opening, and TREMstop® Mortar or Coating for infilling large voids around the combined service bundle. All compound details were cross-referenced with Tremco's tested system documentation to confirm fire rating compliance.

Challenge 3: Sealing of Service Risers & Vertical Utility Shafts

Open and unsealed service risers connecting multiple hospital floors represented one of the highest fire and smoke spread risks on site — vertical shafts act as chimneys in a fire event, allowing rapid spread of smoke and toxic gases between floors and threatening the entire building's occupants. 

Solution: Atlantis prioritized riser and shaft sealing as a critical early work package. TREMstop® Mortar firestop system was used as the primary solution for large shaft openings, providing a robust, load-bearing firestop capable of supporting services passing through the shaft while maintaining the required fire resistance rating. All riser seals were inspected and documented before other works proceeded on those floors.

Challenge 4: Labelling, Documentation & Healthcare Compliance Requirements

Healthcare facilities in Egypt require comprehensive firestop labelling, inspection documentation, and compliance records to satisfy both project handover requirements and ongoing facility management needs. Every penetration required individual identification, photographic record, system type notation, and inspection sign-off — across a large and complex multi-zone hospital facility.

Solution: Atlantis implemented a structured penetration documentation system from day one — assigning a unique reference number to every penetration, recording the system applied, product used, installation date, and inspector sign-off. A comprehensive handover package was compiled including photographic evidence, system data sheets, and a full penetration register — providing ECS Construction and the hospital facility management team with a complete, auditable passive fire protection record.

Operations Summary

The following sequence of operations was carried out by the Atlantis team: 

•Site mobilization and comprehensive MEP penetration audit across all hospital floors — classifying every penetration by service type, substrate, annular space, and required fire rating.

•Prioritized survey and early closure of all service risers and vertical utility shafts using TREMstop® Mortar firestop system.

•Preparation of penetration system selection matrix and individual firestop details for complex, high-density, and multi-service penetration configurations.

•Substrate preparation at all penetration locations — surface cleaning, repair, and priming as required.

•Application of TREMstop® IA+ intumescent acrylic sealant to cable, conduit, and metallic pipe penetrations.

•Application of TREMstop® Acrylic firestop sealant to standard wall and floor penetrations.

•Application of TREMstop® Mortar system to all large openings, service risers, and utility shaft penetrations.

•Installation of TREMstop® Wrap Strips around all combustible and plastic pipe penetrations throughout the facility.

•Application of TREMstop® Coating systems to cable trays and large service openings.

•Installation of smoke and acoustic barrier systems across all designated compartment interfaces.

•Individual labelling and photographic documentation of every completed penetration with unique reference number and system notation.

•Final re-inspection across all hospital zones — reinstatement of any installations disturbed during ongoing construction activities.

•Full handover documentation package — penetration register, photographic evidence, system data sheets, and quality sign-off — submitted to ECS Construction.

Outcome & Performance

Upon completion, Atlantis Contracting delivered a robust, comprehensive passive fire protection system across all areas of Baheya Hospital — utilizing the full Tremco TREMstop® product range to achieve complete fire compartmentation, effective smoke and toxic gas containment, and full compliance with international passive fire protection and healthcare fire safety standards. The completed installation safeguards the hospital's patients, medical staff, critical medical equipment, and essential infrastructure services — contributing directly to the facility's life safety performance, operational continuity, and long-term regulatory compliance. The project stands as a key reference for Atlantis's specialist capability in delivering passive fire protection within critical and sensitive healthcare environments.
