Terms of use

Draft for LTS to replace with counsel-reviewed terms before launch.

What Pre-Con Assist is

An early sizing check. It isn't a sealed calculation, a delegated-design submittal or a shop drawing. It sizes the vertical mullions and estimates anchor loads; continuity, cantilevers, buckling, horizontals, door loads, glass strength, anchor and embed capacity, and seismic or thermal movement are left to final engineering by the delegated-design engineer after award.

Engineering review

A report is issued only after an LTS engineer licensed in the project's state has reviewed it. Projects in states where LTS engineers are not licensed can be sized for information but are not reviewed.

Your inputs

Results depend on the dimensions, wind and code information you enter. Check them against the drawings and the engineer of record's criteria.

Your account

Seats are per person. Keep your password to yourself. Your firm's projects are visible to your firm and to LTS engineers reviewing them.
