Why SQRD2
Clear, buildable and auditable engineering decisions.
SQRD2 supports contractors, designers and Temporary Works Coordinators from design brief through calculation, independent check, construction sequence and controlled issue.
Independent technical judgement
Load path, stability, assumptions, interfaces and construction-stage risks.
Construction-led solutions
Access, installation, sequencing, inspection and safe removal considered.
Direct engineer communication
Focused responses between the site team and designer.
Controlled deliverables
Calculations, drawings, hold points and residual-risk notes.
Live calculation
Watch a working platform design calculate, live.
The same formula-driven tool used on real projects. Change an input and every check updates immediately — no macros, no static drawings.
Live geometry, not artwork
Plan view, section, load dispersion and bearing pressure redraw from the same numbers shown beside them.
Full calculation trace
Qd, contact pressure, dispersed pressure, settlement — every intermediate value visible, not just a pass/fail flag.
Real outputs
Generates an actual design report, calculation report, certificate and inspection checklist from the live inputs.
Development preview — a screening design aid, not an issued design or working-platform certificate.

Temporary works elements
Engineering services shown with the correct construction activity.
Each image represents the temporary works element described. Replace representative images with approved SQRD2 project photography when available.
EXISTING STRUCTURES
Underpinning & structural support
Sequenced pins, needles, local propping, load transfer and party-wall constraints.
PROPPING
Temporary propping & backpropping
Proprietary prop systems, load transfer, backpropping layouts, reactions and controlled release sequences.
CONCRETE WORKS
Formwork, falsework & backpropping
Wet-concrete pressure, support reactions, pour stages, striking and residual slab capacity.
ACCESS & EDGE PROTECTION
Scaffold & access structures
Stability, ties, buttresses, loading bays, foundations and site-specific modifications.
LIFTING & PLATFORMS
Crane mats & working platforms
Outrigger and track reactions, load spread, bearing verification and temporary access-platform design.
ERECTION ENGINEERING
Steel erection & temporary bracing
Frame stability, temporary raking props, erection-stage reactions, sequence effects and holding points.
PRECAST & TEMPORARY STABILITY
Precast panels, beams & columns
Temporary bracing, erection loads, rotation, uplift, column shoes and connection checks.
Fixed-fee packages
CAT 2 design & checking, priced per scheme.
No open-ended quotes. Every package is priced before work starts, to BS 5975:2019, the Eurocodes and CIRIA guidance — so you know the number before you commit.
