Save time and money with MiTek Posi-Strut™

The cheapest solution is not necessarily achieved by using the cheapest parts. Here we compare I-Joist versus Posi-Strut floor systems as a case in point  

In the building industry, the allure of cost-effectiveness often leads to the assumption that cheaper parts equate to the most economical solution. However, this conventional wisdom doesn’t always hold true, especially when comparing I-Joist and Posi-Strut floor systems. Despite the prevailing market perception that Posi-Strut is more expensive than I-Joist, a deeper analysis reveals that cost per lineal metre ($/m) isn’t the only factor to consider. 

Beyond transactional supply decisions 

Supply decisions are often made transactionally, focusing on raw materials and comparing costs per lineal metre ($/m) to expedite estimates. This approach, driven by the desire for quicker cost evaluations, overlooks significant considerations. Decisions on materials are sometimes made by a separate purchasing department without involving input from the build owner or the construction and maintenance teams. This method can miss out on the substantial benefits of purchasing a complete floor system instead of assembling materials separately on-site. These benefits are delivered by MiTek’s Design-Make-Build® methodology. 

MiTek’s Design-Make-Build® Approach  

MiTek advocates a unique, collaborative construction approach with its Design-Make-Build® process, integrating efficient off-site methods into the concept and design phase. This methodology focuses on three key stages:  

Design: Utilising software for workflow, design, estimating and production management. 

Make: Employing automation for off-site construction, enhancing efficiency and quality. 

Build: Using products that improve productivity, optimise build schedules and reduce risk.

Comparative analysis: I-Joist vs. Posi-Strut  

MiTek tested this approach with a comparative side-by-side build, constructing two identical buildings with identical layouts using different methods. One used I-Joist with materials purchased separately and assembled on-site; the other employed the Posi-Strut flooring system, including No Floor Hangers (NFH). Actual costs and timing were meticulously recorded to compare the total cost and efficiency of the two builds, with trades providing unbiased feedback. 

The results were revealing. When considering all material costs, including sub-floor timber and hangers, steel beams, columns and framing bulkheads, the Posi-Strut floor system emerged 2% cheaper than I-Joist. Labour costs were 65% lower for the Posi-Strut project, resulting in a completed build that was 10% less expensive than the I-Joist build. 

Extending Beyond Cost Savings   

The Posi-Strut project saved five days, representing a 30% time improvement, allowing builders
to take on more projects. Besides cost and time savings, the system offers value-added benefits such as waste reduction, fewer errors, reduced risks and enhanced sustainability. Faster project completion improves cash flow and capacity for more work.  

Trades involved in the project attested to the ease and confidence provided by the Posi-Strut system, emphasising its potential to diversify and expand the available labour force within the construction industry. Plumbers and electricians can install pipes, wiring and services without drilling holes, adding another layer
of efficiency and convenience. 

Rethinking construction methods   

Evaluating construction methods means looking beyond initial costs to assess overall value. The Posi-Strut floor system, with its proven efficiency, affordability and performance, is a compelling choice for modern projects and is available from PlaceMakers Frame and Truss. 

MiTek’s Design-Make-Build approach prioritises efficiency, quality and innovation, underscoring a commitment to sustainable, cost-effective and future-proof construction practices.
