Structural Design of ground floor, Amelia Patisserie
Covent Garden Central London
Project Overview
Liba Consulting was appointed to deliver the structural engineering design of a ground floor infill and strengthening for the renovation of Amelia Patisserie in Covent Garden, Central London. The project involved a comprehensive structural analysis to ensure the flooring system was robust enough to meet the requirements of a commercial hospitality space, while specifically addressing the critical need for non-disruptive construction methods.
Key Engineering Challenges
The project required precise structural coordination to support the commercial usage of the space while maintaining operational continuity:
- Operational Continuity: The primary challenge was to design structural elements and connections that could be installed rapidly on-site to avoid closing the shop or requiring destructive works.
- Structural Integrity: Verifying the load-bearing capacity of the existing floor structure and ensuring stability/stiffness to prevent excessive deflection.
- Member Optimization: Managing assessment of existing members while ensuring the design remained buildable within a tight footprint.
Engineering Solutions
Connection Design & Installation
- Fast-Track Connection System: Engineered custom structural connections specifically designed for speed and ease of installation, allowing for minimal on-site assembly time.
- Non-Destructive Methodology: The connection detailing was optimized to ensure that integration with the existing structure could be achieved without extensive site fabrication or destructive intervention, successfully allowing the patisserie to continue daily operations during the installation phase.
Structural Analysis
- Rigorous Verification: Performed comprehensive calculations for design resistance and buckling, ensuring full compliance with Eurocode structural design standards.
- Stability Assessment: Conducted detailed assessments to mitigate LTB risks, verifying the structural adequacy of the floor framing.
- Member Performance: Validated member performance, including imperfection factors and LTB reduction factors, to confirm the system safely supports anticipated commercial loads.
Risk Management & Compliance
A structured technical review was carried out covering:
- Minimizing site disruption through pre-planned installation sequencing
- Structural stability of floor members under operational loading
- Compliance with Eurocode-based design standards
- Mitigation of buckling and deflection risks
Outcome
The project delivered:
- A validated, robust structural solution for the Amelia Patisserie flooring system
- A non-disruptive installation strategy, enabling the shop to remain open during the renovation
- Full verification of floor members meeting rigorous safety and serviceability standards
- Clear, buildable structural specifications for efficient contractor implementation
Why This Project Matters
This project demonstrates Liba Consulting’s ability to:
- Provide expert structural assessment for commercial renovation projects where operational downtime is not an option
- Deliver precision-engineered connection designs that solve complex site logistics and access challenges
- Combine rigorous theoretical analysis (such as LTB stability checks of existing elements) with practical, buildable engineering solutions
- Prioritize safety and regulatory compliance without compromising on project efficiency or client operations
