The Schedule Case Starts With the Subfloor
On a typical 7-story multifamily project, gypcrete adds 14 to 21 days of dead schedule time — cure windows that exist for no reason other than the product requires them. Finish trades are sequenced around a drying clock that has nothing to do with your project timeline or your owner's occupancy target.
DragonBoard eliminates that clock. The panel installs dry, finish trades follow immediately, and the schedule compression is real and measurable.
The Construction Loan Math
Schedule compression has a direct dollar value at the developer level. On a $40M construction loan at current rates, each week of delay carries five-figure interest expense. A 2 to 4 week compression on a 7-story build — which is what switching from gypcrete to DragonBoard typically delivers — is a measurable IRR improvement, not a line-item rounding error.
The subfloor decision is one of the few choices a developer can make that directly affects the construction schedule without adding scope, complexity, or risk. It's a substitution that compresses the critical path.
Revenue Acceleration
Schedule compression pulls forward every downstream activity — punch list, certificate of occupancy, leasing commencement, first rent check, first hotel night sold. On a 200-unit multifamily project, a 2-week schedule pull-forward is meaningful early-cycle cash that compounds against the discount rate in the pro forma model.
Structural Cascade Savings
DragonBoard weighs 4 lbs/SF versus 10 to 15 lbs/SF for gypcrete. On a 100,000 SF building, that's 600,000 to 1,100,000 lbs of dead load removed from the structure. Specified pre-design, the weight reduction cascades into lighter framing members, smaller column sections, and reduced foundation loads.
The structural savings don't appear in the subfloor line item — they appear in the structural package. Developers who specify DragonBoard pre-design capture savings across the entire structural system, not just the floor assembly.
How Developers Drive the Substitution
The most efficient path to capturing DragonBoard's schedule and cost benefits is owner-driven specification. When the developer drives the substitution conversation with the GC directly — with a project-specific cost and schedule analysis — the substitution closes in days, not weeks.
DragonBoard's team provides a 30-minute strategic call where you bring your project parameters and walk away with the substitution argument for your GC, including the schedule math, the installed cost comparison, and the talking points for the owner conversation.
