Overview
Project overview
A private developer needed to bring a residential cluster online quickly, with predictable unit cost and minimal on-site disruption. Asama Bisato delivered factory-built modules, on-site assembly, foundations, and shared utility connections, compressing the build programme versus a conventional cast-in-place equivalent.
The challenge
Site logistics, weather windows, and skilled-trade availability were all squeezing the conventional build schedule. The developer needed cost certainty, a shorter handover window, and a finish quality consistent across every unit.
The Asama Bisato solution
Modules were fabricated off-site in a controlled environment, trucked to site, and craned into place onto pre-poured foundations. Shared MEP (water, drainage, and electrical distribution) was trenched and tied in by Asama Bisato’s in-house crews, with finishes completed module-by-module to keep occupied phases clean.
Results
Outcomes that matter
- Faster handover Compressed programme vs. cast-in-place equivalent.
- Cost certainty Factory-built modules tighten unit-cost variance.
- Less site waste Off-site fabrication reduces on-site offcuts.
- Consistent finish Quality control held in a factory environment.
Scope
