Standards: UL | ASTM | BS | International Passive Fire Protection Standards
Facility Type: Critical Electrical Infrastructure — Power Distribution Substations
Infrastructure Context
Electrical substations represent some of the most demanding environments for passive fire protection — housing high-voltage distribution equipment, densely routed cable trays, critical switchgear, and control systems in a compact, enclosed infrastructure setting. A fire event in a substation can have cascading consequences far beyond the facility itself — disrupting power supply across an entire development, compromising life safety systems, and causing irreparable damage to high-value electrical assets. Fire compartmentation in this context is not merely a regulatory requirement — it is a critical operational resilience measure.
Within Misk City — a large-scale, mixed-use urban development forming a key part of Riyadh's Vision 2030 programme — the six substations serve as the central power distribution nodes for the entire development. Their operational continuity is essential to the function of the wider Misk City infrastructure. The firestop works executed by Atlantis directly contribute to the resilience and long-term operational reliability of this critical infrastructure.
Site Challenges & Atlantis Solutions
Challenge 1: High-Density Electrical Cable Penetrations in Critical Infrastructure
Electrical substations contain some of the highest-density cable routing of any building type — with large cable trays carrying multiple heavy-gauge power cables, control cables, and data cables through fire-rated walls and floors simultaneously. The combination of large annular spaces, mixed cable types, and the critical sensitivity of the electrical environment made penetration assessment and system selection particularly demanding.
Solution: Atlantis conducted a detailed penetration-by-penetration audit across all six substations — classifying each opening by cable type and quantity, tray size, substrate material, and required fire rating. The full Fischer Firestop product range was deployed to match each penetration type: FiAM acrylic sealant for standard cable and conduit penetrations; FiGM mortar for large cable tray openings; FiPW coated board systems for large containment areas; and FiWS wrap strips and collars for any combustible pipe services. All system selections were referenced to Fischer's tested system documentation to confirm compliance.
Challenge 2: Working Within Live & Energized Electrical Environments
Several of the six substations were partially operational or in advanced commissioning stages during the firestop works — meaning Atlantis teams were required to work in close proximity to energized electrical equipment. This imposed stringent electrical safety protocols, restricted access zones, and coordination requirements with the electrical commissioning team that significantly affected installation sequencing and productivity.
Solution: Atlantis developed a dedicated electrical safety working procedure for the substation environment — with all installation team members briefed on electrical hazard awareness, minimum approach distances, and emergency procedures before any work commenced in each substation. Works in proximity to energized equipment were coordinated directly with the electrical commissioning team, with permitted access windows agreed in advance. No firestop works were permitted to commence in any zone without explicit clearance from the electrical team.
Challenge 3: Multi-Substation Coordination Across Six Concurrent Locations
Managing firestop works across six separate substation locations simultaneously — each at a different stage of construction, commissioning, or operation readiness — required careful resource allocation, individual substation work programmes, and centralized quality oversight to ensure consistent standards across all six facilities.
Solution: Atlantis assigned a dedicated substation supervisor for each facility, with a centralized project manager overseeing all six locations. Each substation had its own penetration audit register, work programme, and inspection sign-off schedule. Weekly cross-substation progress reviews were held with Binyah to track completion status, identify access or construction dependencies, and coordinate resource redeployment between substations as each facility's readiness progressed.
Challenge 4: Documentation & Compliance for Critical Infrastructure
Critical electrical infrastructure projects at the scale of Misk City demand the highest level of firestop installation documentation — with full traceability from product batch numbers through installation records to inspection sign-off for every penetration in every substation. This level of documentation is essential for regulatory compliance, facility management, and future maintenance planning.
Solution: As a Certified Fischer Firestop Applicator, Atlantis implemented Fischer's certified applicator documentation standards across all six substations — maintaining individual penetration registers with unique reference numbers, photographic records, product batch traceability, system type notation, and inspector sign-off for every installation. A complete handover package for each substation was compiled and submitted to Binyah at project completion — providing a fully auditable passive fire protection record for each facility.
