Value Engineering: Our Approach
Our approach to Value Engineering is summarized in the quote by the CEO of Jaguar, Dr Ralf Speth who once said that…
“if you think a good design is expensive, you should look at the cost of a bad design”.
Essentially, we do not try to Value Engineer a structural design by simply reducing material marginally, even if it can be justified by code compliant calculations, as this would simply reduce the factor of safety of the building structure. Instead, we Value Engineer a structural design by changing the structural scheme completely (indeed only if it is feasible) for e.g.: –
- by altering the vertical and lateral load paths (and architectural grids if possible) to a more efficient system in high-rise structures
- by converting an RC construction to a longer span post-tensioned (PT) construction in high-rise structures
- by converting an RC / PT construction to a longer span composite steel construction with integrated services in high-rise structures
- by converting a beam and slab construction to a flat slab construction
- by converting an RC transfer floor into a dual-cast post-tensioned (PT) transfer plate in high-rise structures
- by performing automated structural optimization for complex designs such as on a 50-pile pile group pile cap design
- by performing an integrated pile cap and (stiffening) core wall analysis and design
- by performing a more bespoke or customized design considering the actual spans and applied loadings, etc.
whilst maintaining or in fact increasing the structural factor of safety.
Below is our list of selected Value Engineering design work: –
1. Conversion of RC Transfer Beams to a Dual-Cast PT Transfer Plate
2. Composite Cellular Steel Beam Floor With Integrated Services
