Apologize in advance if this has been posted before but we are trying to get manufacturers of stage curtains to give documentation that proves that the product does not have halogenated fire retardants.

I'm looking to compare using an electric tower crane vs a diesel generated tower crane.  I've got the average gallons/hour for the size of crane I'm looking at, but when I reached out to the crane manufacturers, they can only tell me what size electric supply I need to provide, not the kWh usage for the cranes.  I know that it varies depending...

I'd love to hear thoughts from the design, consulting, and contracting firms in this group about ways to make our specs more inclusive, or at least less exclusive to minority and women owned contractors and subcontractors and others that have not had the benefit of what a recent "Equity in Specs" presenter termed the "Fathers / Brothers / In-...

Has anyone had any success with achieving the LEED Building Envelope commissioning points with an alternative compliance path using the requirements of the PHIUS verifier? It seems like an unnecessary duplication to ask the client to pay for a BECx agent and a Passive House verifier. Or am I missing something? I can't find any LEED... Read more

Has anyone here found an alternative to XPS for the void former?

A structural engineering contact was included in recent conversations about embodied carbon in insulation materials and brought to our attention that this is a common use for XPS that has nothing to do with its insulating properties. It is typically used where concrete is... Read more
