Lab-container costs: what really determines the price

Anyone searching the internet for “lab container price per month” finds blanket figures that are worthless. A lab container is never a catalogue product, but always a project-specific configuration. We would be deceiving ourselves – and you as the client – if we wrote down a list of fixed prices at this point.

What we give you instead – and what this guide is about – are the cost factors. Once you understand which eight blocks build a project and which levers actually move the final sum, you can formulate requirements cleanly, make quotations comparable and avoid expensive surprises at the end of the contract. We then take on the concrete costing – free of charge, transparently structured and typically within a few working days after the requirements workshop.

Fact table: the eight cost blocks and their price drivers

Every lab-container project is built from the same eight blocks – whether it is a temporary interim laboratory, a permanent works extension or a pilot cleanroom project. The following table names for each block the standards basis and the factors that actually determine its share of the price.

The next sections walk through each of these eight blocks in turn. Anyone who overlooks a block in the requirements specification builds a budget gap – and that is the most common reason final invoices diverge from the first quotation.

Why there is no list price for lab containers

The reason lies in the nature of the thing: a 30 m² standard analytical laboratory and a 30 m² GMP cleanroom to Annex 1 share the same collective term “lab container” – but in design, material and documentation they are completely different buildings. The HVAC of a BSL-3 module costs a multiple of a standard ventilation module. Complete Annex 15 validation documentation can influence the price of a cleanroom container more than the container shell itself.

Added to this are project-specific variables that nobody could map in a price list in advance: installation site and delivery logistics, connection conditions at the existing building, contract term with index clauses, scalability and funding eligibility, the regulatory path for BSL/GMP/Ex-protection applications. A blanket “from €/month” statement is therefore either a teaser figure that has nothing to do with the real quotation, or a minimum price that describes the standard module in the most favourable case and does not fit 90 per cent of enquiries.

For that reason we at Planexus do not issue blanket list prices. Instead we work through every project individually after a requirements workshop – free of charge, in the same structured form (see Chapter 6) for every interested party. That is no more effort than a lump-sum quotation, but it is honest.

The eight cost blocks in detail

Block 1 – Container shell and basic fit-out

Steel frame construction in weathering or hot-dip galvanised steel, insulated sandwich panels with a project-dependent U-value, raised floor for services routing, washable wall lining, acoustic ceiling, floor covering with coved skirting. This shell accounts, depending on equipment class, for a substantial share of the container price. The exact share hangs on module size, insulation standard to GEG 2024 (§§ 71 ff.) and the fire-protection requirement of the installation site.

Block 2 – Interior fit-out and laboratory furniture

Laboratory run with a ceramic or chemically resistant composite worktop, safety cabinets (FWF cabinets to DIN EN 14470-1 for flammable liquids, gas-cylinder cabinets to DIN EN 14470-2 if required), stainless-steel or PP sinks, eye and body emergency showers to DIN 12899, thermal disinfection in BSL areas. We deliver the complete interior fit-out from the Wesemann group – the furniture components meet DIN EN 14056 for construction and DIN EN 13150 for work surfaces. The price scales with instrument count, special furniture, chemical-resistance requirements and the desired design standard.

Block 3 – HVAC and cleanroom technology

This is where the largest price differences between equipment classes arise. Standard laboratories manage with a split air-conditioning unit and mechanical ventilation. BSL-2 ventilation needs H13 terminal filters, differential-pressure monitoring and higher air-change rates to DIN 1946-7. GMP cleanrooms to ISO 14644 Class 7 (or stricter) need HEPA terminal filters, pressure cascades across several rooms, very high air-change rates and complete validation documentation to EU GMP Annex 15 (DQ/IQ/OQ/PQ). BSL-3 additionally requires emergency extract, autoclavable extract air and standby-power backup. Anyone who saves at the wrong end here fails the validation or the authority audit – HVAC is the most common reason for Annex 1 findings at pharmaceutical inspections.

Block 4 – Safety systems

Fire detection and alarm system to DIN 14675, sprinklers to VdS CEA 4001 or a gas-extinguishing system for sensitive equipment, emergency showers and eye washes, hazardous-substance extract at microbiological safety cabinets to DIN EN 12469, gas alarming for flammable or toxic gases, emergency ventilation with redundant power supply. At BSL-2, an airlock, autoclavable extract and a standby generator are added; at BSL-3, additionally pressure monitors with alarm, emergency shut-down and a personnel airlock with shower. The safety-systems share of the total price grows disproportionately with the containment level – that is mathematically unavoidable.

Block 5 – Structural design, foundation and installation

Load assumptions to DIN EN 1991 (Eurocode 1), bearing capacity of the pad to DIN 1054 and DIN EN 1997 (Eurocode 7), snow-load zone, wind zone, frost depth to DIN EN ISO 13793. Three foundation variants dominate in practice: pad foundations of concrete blocks, strip foundations for multi-storey assemblies, or a continuous reinforced-concrete ground slab for GMP and BSL-3 installation. Screw piles save time on short rental terms, but are not suitable for all soil classes. Installation by mobile crane (40-tonner for one module, 80-tonner and larger for several modules) including traffic management to RSA 21 and a lifting-equipment operator with a competence certificate to DGUV Regulation 52 is a cost block of its own.

Block 6 – Logistics and delivery

Low-loader transport from the Albstadt factory to the installation site. Freight costs scale with number of modules, distance and permit duty: from 3.5 m transport width, a §29 StVZO special permit applies; from 4 m escort vehicles are required; from 4.5 m or for night movements, a police escort. With several modules a fixed-cost share arises for mobile-crane delivery per installation day – bundling several modules in one delivery almost always pays and is one of the most effective levers for logistics-cost optimisation.

Block 7 – Permits and design

Structural proof by a checking engineer to the state building code, building application or notice to §63 or §76 MBO, if applicable a GenTG notification to the regional council at safety level S1/S2 to GenTSV, a radiation-protection permit to the StrlSchG for radioactive substances, an immission-control notification to §15 BImSchG for extract air streams. Design services by an architect or building-services engineer for media and ventilation design – we deliver these services integrated from a single source and relieve the client of coordinating several specialist designers.

Block 8 – Connections

Main electrical connection to DIN VDE 0100, often via a construction-site distribution board with 30 mA residual-current device; the connection rating per module depends on HVAC design and the instrument inventory. Potable water to DIN 1988 Part 100 with Category 5 system separation in BSL areas. Wastewater connection to DIN 1986-100 with a sampling chamber and, if required, a neutralisation plant. Data connection by fibre or optical fibre, often via a leased line to the existing building. On longer service runs, civil works and trenching are added and can quickly multiply the connection-cost item – the position of the pad relative to the nearest handover point is one of the most underestimated price drivers in the entire project.

Equipment classes as price drivers

The equipment class determines the price frame more than raw floor area. Eight classes are relevant in DACH practice – each with its own standards basis and its own costing logic. The following overview shows which factor drives the price in which class.

The typical misjudgement in requirements planning: a containment level that is too high is specified “as a precaution” because it is unclear whether more hazardous agents might be handled in future. That drives the price without real benefit. Conversely, a specification that is too low leads to later retrofit effort that costs more than the direct design would have. An honest requirements workshop with the research or quality manager before quotations are invited is the largest lever for cost optimisation.

Rent vs. purchase vs. hire purchase – the decision matrix

The most common question on the telephone is not “What does it cost?”, but “Should I rent or buy?”. The honest answer hangs on four variables: period of use, capital availability, accounting requirement and the expected technical half-life of the equipment.

The practical rule of thumb we have given clients for years: multiply the expected monthly rent by the planned period of use in months. If the result is clearly below the purchase price, rent. If it is clearly above, buy. In between, the hire-purchase model with credited rental instalments and a residual purchase price at the end of the contract pays – that makes the later switch from a bridging solution to a permanent facility possible without a double investment. Concrete rental rates and purchase prices we cost individually after a requirements workshop. The detailed qualitative advantages and disadvantages are set out in the separate article lab containers: rent or buy.

The seven hidden cost items

Seven items regularly disappear from discount quotations – but they reappear at the latest on the final invoice. Anyone who knows them asks for them actively and prevents the nasty surprise.

1. Strip-out at the end of the rental: dismantling, removal, reinstatement of the pad. Often mentioned only as a clause “strip-out at the tenant’s cost”, without a price in the quotation.
2. Continuous HVAC electricity: BSL and cleanroom containers draw substantial year-round base load. That does not appear in the rental quotation – but it does on the university’s or company’s electricity bill. Energy costs over the contract term can become a substantial OPEX item.
3. Filter changes: HEPA terminal filters H13 at BSL-2 change every 12 to 24 months; ULPA filters in an ISO 5 cleanroom correspondingly more often. Material costs plus a service charge per change.
4. Re-qualification after a site move: every analytical instrument must be IQ/OQ/PQ-validated after relocation. At accredited test houses to DIN EN ISO/IEC 17025, a DAkkS site notification is added.
5. Insurance: all-risks cover for rented containers is usually the tenant’s responsibility and is often not shown in the quotation.
6. Maintenance contracts: HVAC, filters, fire detection and alarm system, emergency showers – often not included in the base rent, but to be agreed separately.
7. Index clauses: rental rates rise with the consumer price index or an agreed annual escalation rate. Over a multi-year term the rate can move substantially from the opening quotation – the clause belongs on the table explicitly.

The 14-point quotation comparison checklist

Comparability only arises if you give every supplier the same point list. These fourteen points belong in every briefing:

1. Number of modules, internal dimensions L × W × H, usable area in m²
2. Equipment class with standard reference (standard, GLP, GMP class, BSL level, ISO 14644 class)
3. HVAC design in kW and air-change rate per hour
4. Filter stages F7/F9/H13/H14 and maintenance intervals in months
5. Electrical connection rating in amperes per module and maximum continuous load in kW
6. Water and wastewater connection including purified-water treatment if required
7. Fire-safety concept, sprinklers or gas-extinguishing system, fire detection and alarm system
8. Monthly net rental including an explicit list of included services
9. Minimum rental term and extension options with a concrete price-adjustment formula
10. One-off costs for delivery, installation and strip-out, each shown separately
11. Foundation and structural requirements with load assumptions in kN/m²
12. Validation and qualification documentation IQ/OQ/PQ including scope
13. Maintenance charge and guaranteed response time for faults
14. Optional: resale value or buy-back option at the end of the rental with a concrete residual-value factor

With this list, discount suppliers and serious suppliers become directly comparable for the first time. We at Planexus issue every quotation in exactly this structure – on one sheet, without asterisks, without “as incurred” at the end of the contract.

Funding and financing 2026

Four funding routes are relevant in practice. Federal research and innovation funding via BMBF, BMWK and project management agencies (DLR, Jülich, VDI/VDE-IT) – third-party projects can claim container rentals and purchases as capital or rental-cost items, provided they are eligible project costs under the funding guideline. State development banks (NRW.Bank, L-Bank, LfA Bayern, IBB) offer interest-subsidised investment loans for SMEs and research institutions, often with repayment-free years. EU programmes Horizon Europe and EIC Accelerator accept container solutions as CAPEX or OPEX. KfW programmes such as the ERP SME loan and the KfW climate-protection offensive offer subsidised terms for energy-efficient modular laboratories.

On larger investment schemes a funding review almost always pays; we recommend involving the in-house third-party funding office or a specialised adviser in the pre-project phase. Processing time for a KfW application is typically six to twelve weeks; BMBF funding applications take six to nine months – this lead time must be built into the project plan.

How a serious costing runs

From the first telephone call to a robust quotation, five to ten working days typically elapse at Planexus. The process follows a clear four-step model:

Conclusion

A serious lab-container quotation does not consist of a lump-sum figure, but of eight clearly costed blocks plus five one-off items plus seven transparently shown follow-on costs. Anyone who knows this structure can compare suppliers directly for the first time – and avoids the expensive surprises with which discount quotations regularly end.

The concrete costing is always project-specific. It hangs on application, containment level, installation site, contract term and regulatory path. We supply it free of charge, in the fourteen-point structure described here, typically within a few working days after the requirements workshop.
