How It Works – Builders

BOSS for Developers, Builders & Contractors

Built Faster. Built Better.

A finished panelized structural + MEP system that replaces the most unpredictable parts of construction and collapses months of work into a 2–4 week shell & core installation.

Press Release

BOSS (Built On-Site Systems) announced today the expansion of its technologically advanced, California code-compliant panelized building system designed for developers, builders, architects, and general contractors seeking faster and more predictable construction.

The BOSS system replaces the most labor-intensive and inspection-heavy scopes of a project – framing, sheathing, Weather Resistant Barrier, insulation, electrical and plumbing rough-ins, mechanical chases, interior drywall, and fire/sound/energy assemblies – with a factory-produced finished panel system that installs onsite in 2–4 weeks.

By comparison, the same scopes typically require 13–22 weeks using traditional construction methods (source: National Association of Home Builders).

The BOSS system eliminates multi-trade sequencing risk, reduces dependencies, accelerates pro formas, and provides a predictable path to a paint-ready shell & core. Developers, builders, and contractors can now submit plans for a BOSS Conversion Review to evaluate schedule, cost, and labor savings.

Frequently Asked Questions

  • What is the BOSS System?

    BOSS is a finished panelized structural + MEP building system that replaces the most complex segments of the construction process.

    Each closed panel contains:
    – Structural steel or hybrid framing
    – Cement board exterior
    – Drywall interior finish
    – Integrated electrical raceways
    – Plumbing pathways
    – Mechanical chases
    – Fire, sound & energy-code assemblies
    – Insulation
    – Vapor and moisture protection

    The panels arrive fully factory-finished and install into a completed paint-ready shell & core.

  • What problem does the BOSS system solve?

    BOSS directly addresses the top failure points in construction:

    1. Labor shortages & trade stacking – Traditional builds require 7–10 sequential trades. BOSS replaces these with one installation crew.
    2. Unpredictable timelines – Factory production eliminates most of the Seven Inspection Stages.
    3. Cost variance – Variable field labor becomes a fixed factory scope.
    4. Pro forma delays – Collapsing shell & core from 13–22 weeks to 2–4 weeks accelerates downstream schedules.
    5. Construction complexity – The system simplifies and de-risks the hardest part of building.
  • How does BOSS compare to traditional construction schedules?

    Traditional Construction Shell & Core (NAHB): 13–22 weeks.
    BOSS Shell & Core Installation: 2–4 weeks.

  • Is BOSS modular or prefab?

    BOSS is not volumetric modular and not conventional prefab. It is a finished closed-panel system engineered for rapid onsite assembly using standard GC labor, providing architectural flexibility while eliminating multi-trade complexity.

  • What types of projects is BOSS designed for?

    Single-family homes, ADUs and infill housing, two-story subdivisions, small-lot developments, multi-unit residential, affordable and workforce housing, interim/supportive housing, and light commercial structures.

  • What codes does BOSS comply with?

    BOSS complies with the International building code (IBC), the California Residential Code (CRC) and California Building Code (CBC). Panels meet or exceed structural, fire, sound, and energy requirements.

  • What is a BOSS Conversion Review?

    A complimentary evaluation of your architectural drawings that includes:

    1. A full BOSS system conversion of your design
    2. A construction sequencing plan
    3. A schedule, budget, and timeline savings report
    4. Structural engineering review and load-path guidance
    5. Optimizations to improve panelization and installation speed

  • How does installation work?

    Option A – BOSS Turnkey Installation: BOSS performs the shell & core installation as a licensed general contractor.

    Option B – Builder/G.C. Installation: Your team installs using panel drawings, sequencing plans, and BOSS site support.

  • What happens after the shell & core is installed?

    Your project is delivered paint-ready. Builders complete paint, flooring, cabinetry, fixtures, exterior finishes, and final MEP connections. BOSS accelerates the critical path while maintaining full finish flexibility.

  • How does BOSS address the fragmented nature of traditional construction?

    Traditional construction requires coordinating nine major scopes and numerous trades before achieving a functional shell & core. Each trade introduces risk, delays, and variability. BOSS consolidates all nine scopes into one factory-built system. By delivering finished structural and MEP panels, the system eliminates trade stacking, reduces sequencing challenges, and brings predictable speed and control to the project.

  • How does BOSS reduce the number of inspections and onsite coordination required?

    Most inspection-heavy scopes – framing, insulation, electrical, plumbing, mechanical, shear, fire, sound assemblies – are completed within the factory under controlled QA/QC. As a result, onsite inspections are minimized because code compliance is achieved before panels arrive. This simplifies coordination, reduces rework, and keeps projects moving without inspector-related bottlenecks.

  • What does the BOSS system cost?

    BOSS is priced at the cost of traditional wood framing but saves 50%+ in build time while reducing labor, carrying costs, and pro forma risk. Developers benefit from predictable budgeting and accelerated timelines.

  • How does BOSS improve a developer’s financial pro forma?

    Delays in shell & core drive up loan interest, carrying costs, labor escalation, and delay revenue generation. By compressing shell & core from 13–22 weeks to 2–4 weeks, BOSS accelerates all downstream trades and shortens the overall construction timeline. Developers benefit from improved IRRs, earlier occupancy, lower financing overhead, and a more reliable project schedule.

  • Why is BOSS expanding to developers, builders, and contractors?

    After extensive work with cities and municipalities to deliver rapid housing, demand from private developers and builders for faster, more predictable construction has increased significantly. The BOSS system provides the labor efficiency, schedule reliability, and system-based construction method needed across the private sector.

  • What is the long-term vision of BOSS?

    To replace slow, labor-heavy construction with system-based building, making housing faster, predictable, less labor-intensive, scalable, and accessible to all.
