Precast Structural Design Calculations

We prepare comprehensive precast structural design calculations to ACI 318-19, Eurocode, BS and PCI — covering complete elements and their connections at ultimate and serviceability limit states, with clear, auditable output. Explore our design-calculation services below.

Building Design

3D structural model of a precast concrete building frame with wall panels and roof.

Complete precast building design — frame elements, bearing-wall systems and insulated sandwich panels: flexure, shear, connections, deflection and lifting, to ACI 318-19 and PCI.

Lifting Design & Analysis

Precast lifting arrangement showing lifting inserts and rigging.

Structural design of precast lifting inserts and handling — anchor capacity, concrete breakout, shear and rigging — to ACI 318-19 and PCI for safe demoulding, handling and erection.

Boundary Wall Design

3D render of a precast concrete boundary wall with pilasters and infill panels on strip footings.

Free-standing precast boundary walls as a complete system: wind load, panel wall and beam action, RC columns, footings, and dowel or pocket connections (including firewall panels), to ACI 318-19, BS 8110 and Eurocode.

Firewall Panel Design

Finite-element model of a precast firewall panel under out-of-plane lateral load showing lateral deflection.

Tall free-standing precast firewall panels governed by out-of-plane lateral load (greater of wind and blast overpressure) and stability: flexure and shear, deflection, crack width, base connection and lifting, to BS 8110.

Hollow Core Slab Design

Precast hollow core slab cross-sections showing voids and prestressing strand layout.

Prestressed hollow core slab design across depths from 150 to 500 mm: prestress losses, flexure, shear, deflection and camber, bearing and lifting, to ACI 318-19, PCI and BS EN 1168.

Cover Slab Design

Finite-element model of a precast cover slab with openings.

Reinforced precast cover slabs: flexure, shear, crack-width control, standard-hook development length, load cases, bearing and lifting, to ACI 318-19.

Footing & Foundation Design

Typical precast column to precast footing connection detail: dowel bars, non-shrink grout and levelling shims.

Precast footings and pocket / socket foundations: bearing pressure, flexure, one-way and punching shear, crack width and connection design, to ACI 318-19.

Retaining Wall Design

Section view of a precast retaining wall with stem, base and soil profile.

Precast retaining walls: sliding, overturning and bearing-pressure stability, stem and base design, crack-width control and lifting, to ACI 318-19.

Block & Mass-Concrete Design

Precast block top view and section with lifting loops and reinforcement.

Precast blocks and mass-concrete elements: flexure, shear, crack-width control, interface shear-connection reinforcement and lifting, to Eurocode 2 (EN 1992).

Pylon & Signage Design

Erected precast concrete pylon with twin columns and an upper beam.

Precast pylon and signage structures: wind load, footing flexure/shear and punching, crack width, pocket connection and upper-beam design, to ACI 318-19.
