Local Installation vs. Technical Supervision: Clear Site Boundaries
Understanding the exact contractual boundary between certified manufacturer supervision and local contractor labor. Crane rigging, module-to-module bolting, temporary waterproofing, and jurisdictional safety liabilities.
1. What Technical Supervision Means (and What It Does Not)
A SERMODULA factory installation supervisor is an experienced structural engineer or master technician dispatched to the client's construction site. Their role is to provide technical guidance, verify assembly tolerances, monitor torque ratings on structural bolts, and oversee acoustic and weather-sealing gaskets.
The supervisor does NOT replace the local general contractor. The supervisor does not provide physical manual labor, does not sign as the local site manager (Bauleiter / Directeur de chantier), and does not hold health and safety (HSE) liability for local workers or mobile crane operators.
2. Critical Quality Milestones Controlled by the Supervisor
Before crane hooks engage the first module, the supervisor verifies foundation slab flatness and embed anchor bolt coordinates against the tolerance threshold (±5 mm). An uneven foundation will multiply dimensional errors across upper floors if not shimmed correctly.
During placement, the supervisor inspects neoprene acoustic decoupling strips between stacked modules, checks alignment dowels, directs perimeter flashing installation, and signs the weather-tight envelope sign-off before evening crane demobilization.
3. Commercial Terms: Daily Fees, Expenses & Weather Delay Protocols
Supervision is typically billed as an engineered package comprising mobilization travel, accommodation, and a daily rate for an agreed duration (e.g., 3 to 7 working days per building stage).
Contracts explicitly define weather standby protocols: if high winds (>12 m/s) or extreme storms prevent safe crane lifting, the supervisor remains on standby. Clear protocols prevent disputes regarding daily rates versus contractor delay responsibilities.

| Task / Scope | Local General Contractor (Client Scope) | SERMODULA Technical Supervisor |
|---|---|---|
| Foundation Slab & Anchors | Excavation, concrete pouring, leveling, anchor placement | Dimensional inspection & tolerance sign-off before unloading |
| Mobile Crane & Riggers | Crane hiring, street closure permits, certified rigging crew | Directs lifting sequence and inspects spreader bar rigging angles |
| Module Placement & Bolting | Physical positioning, manual wrenching and drift pin insertion | Verifies alignment, checks torque wrench values, logs bolting QA |
| Inter-Module MEP Hookup | Local licensed electricians and plumbers connect mains feeds | Explains manifold diagrams and inspects test-pressure gauge readiness |
