Scope Breakdown: What Turnkey Modular Really Means

A clear delineation between factory-finished scope, logistics interfaces, and site-delivered groundwork to prevent cost surprises.

1. The Turnkey Concept & The Need for an Itemized Bill of Quantities

In modular industrial construction, clarity of scope is paramount. Our turnkey proposals precisely differentiate between factory manufacturing, shipping and destination site erection. A generic marketing phrase like "turnkey" is replaced by a verified 175-item cost demarcation matrix.

Understanding which items are factory-integrated and which rely on local subcontractors guarantees seamless project delivery without financial discrepancies or contentious disputes.

2. Factory-Integrated Scope (90% Completion Rate)

All structural steel framing, thermal insulation layers, 3-pane argon glazing, full internal finishes and tested sanitary pods are executed in the factory under climate-controlled conditions.

Factory manufacturing eliminates weather delays, reduces on-site labor requirements by up to 70%, and ensures millimeter-precision execution.

3. Across the Plot Boundary: Foundations, Crane & Civil Utilities

Items situated on the ground belong strictly to civil site operations: concrete foundations, earthworks excavation, crane assembly staging, and municipal grid tie-ins (power, water, sewage).

SERMODULA delivers complete foundation load reaction drawings and anchor interface packages to allow your local civil engineer to execute foundations seamlessly before modules arrive.

Frequently Asked Questions

Does turnkey include foundation excavation and concrete casting?
No. Civil foundation works are executed locally by a civil contractor based on SERMODULA engineering interface and load reaction drawings.
Does SERMODULA build permanent permitted homes or temporary modular containers?
SERMODULA builds 100% permanent residential architecture on concrete foundations complying fully with European building regulations, Eurocode standards and local zoning laws. They are permanent real estate assets designed for a 60+ year lifespan.
Where are the volumetric modules manufactured and what quality standards apply?
All modules are manufactured in our modern offsite facilities in Türkiye under EN 1090-2 (EXC3) execution class for structural steel, CE conformity marking and ISO 9001 certified Inspection and Test Plans (ITP).
How are acoustic and fire separation performance guaranteed between apartments?
When volumetric modules unite, an independent double-steel-wall system with decoupled air cavity and acoustic damping is created, achieving airborne sound insulation of Rw >= 58 dB and fire resistance of REI 90 to REI 120.
How are turnkey modular costs calculated without hidden extras?
Instead of quoting vague single-figure square meter rates, our 175-item cost baseline itemizes factory fabrication, road/sea freight, craneage, local foundations and engineering fees in a transparent project feasibility budget.
