Smarter, lighter, faster – the offsite revolution with Light Gauge Steel Framing
Sigmat have had continued growth in my time here and have the statistics to show that we are market
leaders in terms of turnover & market share
The Construction Industry is showing a remarkable shift & appetite for offsite methods of construction
& the LGSF market is expanding at a rapid rate Quite a revolution I hope you’ll agree?
My aim for today is to demonstrate how light gauge steel frame solutions (LGSF) have delivered cost, time
and energy savings through innovations in manufacturing and digital technologies.
To this end, the University of Hull student accommodation project will form the basis for this.
1. What methods of construction were considered & evaluated?
LGSF, In-situ Concrete, Timber Frame & Pre-Cast Concrete
So why did Vinci choose Sigmat for the largest ever UK LGSF project?
2. What was the overriding reason to choose LGSF?
a) In-situ concrete could not deliver to programmeb) Pre-cast was too expensive and required a greater level of
detail prior to manufacturec) Timber Frame was ruled out early due to the storey heights
amongst other things… (9 storeys is well within the Sigmat LGSF capabilities)
3. How did the programmes of each method considered compare to LGSF?
a) Pre-cast Concrete – similar programme but more expensiveb) In-situ Concrete – couldn’t hit programme
4. Apart from programme & cost, what else was key to the Sigmat LGSF submission?
The ability to offer a scaffold less build by utilising our bespoke Edge Protection System
4. Did utilising a lighter frame offer savings in the ground? If so, can you offer an approximate percentage against each method considered?
Not sure what the percentage would be, too much of an open question. But it does obviously offer savings in the ground due to lighter frame weight.
We have done some quick calculations & based on a Sigmat frame with concrete floors, we are roughly:
• 6.6% lighter than a traditional steel frame with concrete floors and lightweight stud partition walls• 53% lighter than a similar concrete frame building
Sigmat weight per m2 / dead load appraisal
5. How did Vinci feel the project benefitted by utilising LGSF & did they achieve greater productivity as a result?
1) The blocks were all similar so detailing was consistent2) The aim was to develop the first block ASAP (which we achieved)
3) The system avoided the use of scaffolding which was key 4) Mast climbers were predominantly being used for the
external treatment

To this point, hopefully I’ve demonstrated how light gauge steel frame solutions (LGSF) can deliver cost,
time and energy savings by showcasing the University of Hull student accommodation project.
So what about innovations in manufacturing and digital technologies…?
