1200 Hours

Data Collection on SH4 Build Time

See spreadheet [1] from SH4 Data Collection.

We are at around 900 hours up to 11/19/24 inclusive. Then it is a bunch of interior finish work, so let's check. The paiting part ran way out of control because production-grade beadboard takes an estimated 3x the time than drywall - due to the added time of caulking imperfections, 2-3 extra coats for the finish required due to the crevices in beadboard which make multiple angle passes necessary, and the open ceiling on first floor which was a painful job due to finish requirements of the subfloor plywood and excessive amount of coats to cover stains in the joist lumber. So the accurate estimate for drywall would be approximately 1/3 the time for the sand-caulk-paint-sand-caulk-touchup required in the beadboard process. This should be replaced by (mud-sand)-paint (multiple mud-sand cycles) - which is more easy because the surfaces are flat, and there is no initial sand step requirement. And also note that beadboard is highly trimmed - ceiling seams, transition seams - where drywall does not require ceiling seam trim.

After more careful analysis - “Beadboard sheet (4×8) installation is moderately slower than drywall due to bead registration and seam management—especially on ceilings. However, the primary labor multiplier remains finishing/painting. For this build, including installation, the effective multiplier is approximately ~4× versus a drywall interior.” [2]

Ok, so with a major correction factor on interior sheathing install-finish - we continue to count hours.
