6 months
Sainsbury’s is one of the largest supermarket chains in the United Kingdom. For this retail development, Karno Energy was responsible for the design, coordination, and BIM delivery of the wet fire protection sprinkler system.
The project required strict compliance with fire protection standards, coordination with multiple trades, alignment with architectural reflected ceiling plans (RCP), and preparation of construction-ready documentation.
[ Challenges ]
Coordinating Fire Protection Systems Within a Busy Retail Environment
The sprinkler system needed to be coordinated with multiple disciplines while maintaining full fire protection coverage throughout the supermarket.
- Retail ceiling zones
- Multi-trade coordination
- Fire protection compliance
- Coverage validation
Without proper coordination, this would normally result in:
- System clashes
- Coverage gaps
- Installation delays
- Compliance risks
Aligning Sprinklers with Architectural RCP
All ceiling-mounted sprinkler heads had to be aligned with reflected ceiling plans while maintaining compliance with fire protection standards.
- Architectural RCP coordination
- Sprinkler positioning
- Ceiling element integration
- Visual consistency
This created risks such as:
- Architectural conflicts
- Coverage issues
- Late-stage redesign
- Construction delays
Ensuring Installation Efficiency
The installation team required highly detailed BIM models and documentation to support fast and accurate sprinkler installation.
- Detailed riser drawings
- Pump room layouts
- Construction visualization
- Installation planning
Without sufficient detailing, this would normally result in:
- Site modifications
- Installation errors
- Rework during construction
- Extended installation time
[ Solutions ]
Fire Protection Compliance Validation
Before detailed modelling began, sprinkler coverage and design solutions were reviewed to ensure compliance with fire protection standards and project requirements.
- Validation activities included:
Multi-Trade BIM Coordination
The sprinkler system was coordinated with architectural, structural, and MEP disciplines to eliminate conflicts before construction.
- BIM coordination focused on:
This ensured smooth installation and reduced coordination risks.
Architectural Ceiling Alignment
Special attention was given to aligning sprinkler heads with reflected ceiling plans while preserving full fire protection coverage.
- Coordination activities included:
Construction-Ready Delivery Package
The installation team received highly detailed BIM documentation and visualizations to support efficient construction delivery.
- Final deliverables included:
The final BIM package improved installation efficiency and reduced construction uncertainty.
[ Scope of Work ]
The initial project scope included
Our team reviewed sprinkler design solutions, coordinated fire protection systems across all disciplines, and prepared detailed construction documentation in accordance with Sainsbury’s standards.
SPRINKLER SYSTEM DESIGN REVIEW
BIM MODELLING & MULTI-TRADE COORDINATION
CEILING COORDINATION & COVERAGE VALIDATION
CONSTRUCTION DRAWINGS & BIM ASSET DATA
Detailed sprinkler documentation, riser drawings, pump room layouts, and BIM asset information prepared for installation.
[ Delivery Process ]
Fire Protection Review & Coverage Validation
The project began with a comprehensive review of sprinkler design solutions to ensure compliance with fire protection requirements and Sainsbury’s standards.
- So we started with the key project requirements:
-
Validate sprinkler coverage
-
Review fire protection standards
-
Optimize sprinkler layouts
- Following approval, the coordination strategy was established:
-
Coverage requirements
-
Ceiling coordination rules
-
Installation standards
BIM Modelling & Ceiling Coordination
The sprinkler system was modelled and coordinated with architectural, structural, and MEP disciplines to ensure complete integration throughout the supermarket.
- Key coordination activities included:
-
BIM sprinkler modelling
-
RCP alignment reviews
-
Multi-trade coordination
This ensured that sprinkler heads remained architecturally aligned while maintaining full fire protection coverage.
Construction Documentation & Installation Support
Detailed BIM deliverables and construction drawings were prepared to support installation teams and improve construction efficiency.
-
Wet & dry sprinkler system drawings
-
Detailed riser documentation
-
Pump room layouts
The final BIM package provided installation teams with clear documentation and visualization, reducing uncertainty during construction.
[ Results ]
The project delivered a fully coordinated fire protection BIM package that improved installation efficiency, ensured fire safety compliance, and supported successful project delivery.
