Swinerton Mass Timber

works; how fire-rated partitions work; how the exterior enclosure works; how concrete and foundations work. So, when we’re evaluating a mass timber structure, we’re really showing how it can be integrated into those other systems, what cost-saving ideas are integrating into those other systems, and really sharing that with the client, dispelling any concerns they may have with what the unknowns are. Because we are a GC at heart, we understand the neighboring systems, how they are impacted, and how to solve those types of problems. We are a unique partner on a project because we understand the whole building, not just the timber component.” When comparing costs to other structural types, Evans explains that there are five major considerations: shipping costs, exchange rate risk, commodity pricing risk, the regional pricing of comparable structural systems, and the cost analysis of building a lighter weight building with a mass timber structure. Shipping pricing is dependent upon the selected manufacturer and distance required to ship the product to the project site. Exchange rate risk affects European and Canadian supplied product, while commodity pricing affects all timber supply. Regional pricing for structural steel and concrete vary across the US, so fully understanding the regional cost of the mass timber building and comparable systems is important. Evans states that “it is important not to overlook the cost savings to neighboring systems. A mass timber structure is lighter than concrete and steel structures, saving time and money with ground improvements and foundation work. Those benefits need to be realized in the cost model. Also, the schedule for a mass timber building is quicker by a minimum of 15 percent for most structures, meaning there is savings for the general contractor’s site management team.” “There are certain markets where the conditions are really ripe for mass timber to be cost advantageous, and then there are others where it might be a slight cost increase,” Evans admits.
