What Comten handles.
Comten's commercial practice centres on post-tensioned and reinforced concrete slab design for healthcare, government, mixed-use and multi-storey residential projects. The key difference is not just design capability; it is Lewis's availability to solve site issues quickly and keep the structural intent close to delivery.
01
Post-tensioned (PT) slab designLead capability
Long-span, deflection-controlled slabs for healthcare floors, suspended carparks and multi-storey residential projects.
02
Reinforced concrete and precast
Conventional RC framing, precast panel design and transfer structures with practical detailing for construction.
03
Multi-storey and mixed-use
Structural design for commercial, mixed-use and multi-residential buildings where coordination and buildability matter.
04
Early Contractor InvolvementECI
Working with the head contractor during pre-construction to test slab systems, foundations, staging and structural risk before decisions lock in.
05
Staged delivery consulting
Preliminary schematic design, BA/tender documentation, construction documentation and construction-stage support.
06
On-site problem solvingLewis emphasis
Direct engineering availability for site issues, RFIs, inspections and practical decisions during construction.
07
Value engineering for high-cost projects
If a current structural solution feels expensive, Comten can review whether the structure is sized to what the building actually needs.
08
Builder, architect and certifier coordination
Clear technical communication across the people who need to price, approve and build the structure.
Selected capability.

Commercial questions.
Yes. Early structural input is one of the clearest ways to test slab systems, grids, foundations and staging while changes are still cheap.
Yes. RFIs, shop drawing review, site visits, RPEQ inspections and Form 12 aspect certificates are part of the construction-stage support pathway where required.
