Wind-load and system design
Project wind actions are translated into design loads for panels, rails, brackets, mullions, transoms and fixings, with zones and governing cases clearly identified.
Performance and calculations
A result is only useful when the basis is visible.
ALM connects project inputs, current geometry, governing cases, results and limitations so calculations can be reviewed against the proposed envelope.

Checks and evidence
One design basis. Several connected checks.
Brackets, fixings and cantilevers
Support systems are checked for the worst credible bracket cantilever, fixing position, load combination, adjustment range and recorded substrate condition.
Movement and deflection
Structural movement, thermal movement, inter-storey behaviour, tolerances and serviceability limits are coordinated with joints, seals and brittle finishes.
Thermal performance
U-values, repeating thermal bridges, condensation risk and interface continuity are assessed where appointed, using the actual build-up and defensible material properties.
Inputs, outputs and limits
Use defensible inputs and make the governing result easy to review.
Current project basis
Design criteria, geometry, material properties, structural substrate, fixing data, wind information and interface details.
Reviewable outputs
Calculation reports, marked-up governing zones, design reactions, fixing requirements, limitations and linked detail references.
The right point to appoint
When calculations must validate a proposed facade system, answer review comments or support technical submission.
