Technological advances are also primary drivers of construction material innovations. …Also, there are new types of structures that are economically viable only thanks to their novel employment of existing but relatively fresh-on-the-scene materials. …Plus, external economic factors can pack a wallop and play an important role. Obviously, at present, there are the cost consequences of the exorbitant tariff structure attached to the usage of steel, aluminum, and copper. …Mass timber is making a bid to be the wall, floor, ceiling, and load-bearing substitute for steel and cement in building construction projects. The selling points laser in on sustainability and the potential for prefabrication. The subset products all see dimensional lumber bonded together. Glulam has grains running parallel; cross-laminated (CLT) has grains fashioned perpendicularly; and nail-laminated (NLT) and dowel laminated (DLT) are obvious in how they are tied together. …Finally, kudos should be awarded to the Green Building Council.
