About the Project
Pan Gulf Technologies Limited delivered structural design, unit drawings, and shop drawing services for precast chambers and cover slabs in the UK. The project included designing chamber walls with large openings using pinned bottom connections and detailed support logic, all modeled and validated using STAAD software.
Client Overview
The client required precision-engineered precast chamber solutions compliant with UK and Eurocode standards, including both structural analysis and constructibility considerations. Pan Gulf stepped in to design and validate key elements under geotechnical loading conditions.
Scope of Work
Engineered precast chambers and cover slabs with structural design and detailing. Analyzed chamber walls (with large openings) using STAAD Connect, employing pinned bottom connections and upper wall freedom. Conducted base slab analysis for upthrust loads with appropriate restraints on critical faces. Designed construction staging with two-stage casting: chamber walls (including RFA strata boxes and couplers) followed by base slab with reinforcement lapping.
Key Challenges
Handling large chamber wall openings within structural limits. Modeling accurate interface behavior—walls pinned at the base while remaining free at the top. Ensuring stability against upthrust and incorporating multi-stage casting with embedded components.
Solutions Delivered
Pan Gulf Technologies utilized STAAD Connect to conduct precise structural analysis, including uplift and support reactions. The team optimized the design for stability and constructibility, integrating strata boxes and couplers seamlessly into the casting sequence. Continuous verification ensured build-ready deliverables
Software Used
STAAD Connect – for structural modeling and analysis.
Tedds – for structural calculation and design validation.
Results Achieved
Delivered fully engineered precast chamber designs and documentation for safe, staged casting. Ensured structural reliability through uplift analysis and accurate support behavior modeling. Managed embedded detail integration—like strata boxes and couplers—to support secure build sequencing.
