Cost Items
Work on an existing warehouse almost always breaks down into the same categories of operations. Reviewing them in advance allows for comparing homogeneous quotes and understanding where a low figure simply indicates missing items.
- Construction works: flooring, concrete pours, openings, repairs, waste disposal.
- Electrical and lighting system: panels, lines, light fixtures, emergency lighting.
- HVAC and air treatment system: heating, cooling, exhaust.
- Interior spaces: offices, changing rooms, restrooms, technical rooms, mezzanines.
- Safety and compliance: egress routes, fire compartments, signage, commissioning.
- Exterior works: paved areas, fences, facades, roofing and flashing.
Indicative Per-Square-Meter Ranges
The following values are orders of magnitude for interventions on existing buildings in good structural condition: they serve to establish a budget, not to replace a detailed bill of quantities.
Initial conditions drive up the total cost: presence of materials requiring disposal, non-compliant systems, roofs needing integration, and production constraints requiring work in shifts.
| Intervention | Indicative Range |
|---|---|
| LED Relamping with Sensors | 12–28 €/sqm |
| New Electrical Distribution and Panels | 30–70 €/sqm |
| Turnkey Interior Offices | 700–1,200 €/sqm |
| Changing Rooms and Restrooms | 900–1,500 €/sqm |
| Continuous Industrial Flooring | 35–90 €/sqm |
| Comprehensive Integrated Renovation | 250–600 €/sqm |
Variables That Impact the Quote
The same scope of work can vary significantly in cost depending on the context. Before evaluating any figure, it's advisable to establish these points.
- Existing conditions: structural inspections, asbestos, outdated systems.
- Production continuity: working overnight or during plant shutdowns increases construction costs.
- Office finish level: from functional space to representative executive suites.
- Electrical loads required by machinery: determine transformer, panels, and lines.
- Urgency: Compressed project timelines require more parallel teams.
Incentives and Tax Credits
Investments in capital goods, energy efficiency, and training may qualify for tax credits and incentive mechanisms, which change annually. While we do not handle these directly, we prepare the technical documentation — bills of quantities, specifications, reports — that the client's tax consultant uses for their application.
How to Build a Realistic Budget
Our recommended approach: technical site visit, scope definition with ownership, cost estimation by work categories with a 10-15% contingency, and only then the final bill of quantities based on executive drawings. Those who start with a per-square-meter price heard over the phone regularly face change orders once construction is underway.
Frequently asked questions
- Is an architect's design required before requesting a quote?
- No: we can start even with a verbally described need. For complex projects, we can develop the executive design ourselves, coordinating with the client's professionals.
- How long does it take to renovate a 2,000 sqm warehouse?
- For an integrated project involving systems + interior spaces, it generally takes 4-8 months of construction, which can be reduced by working in sections and utilizing production shutdowns.
- Can work be performed without halting operations?
- In most cases, yes: we organize the construction site into zones, with physical barriers, protected pathways, and disruptive work concentrated on weekends or during scheduled shutdowns.
