Whether a commercial hall reaches turnkey in 10 months or the move-in slips by half a year is usually decided long before the first shovel hits the ground. Cost and construction time hinge on a handful of early decisions: layout, facade system, foundation, building services and the permit.
We build halls across the Berlin region from our base in Wildau. For BERTH Werbung in Gallun near Mittenwalde we handed over a two-storey hall with an attached office building turnkey in 10 months, on schedule, including architecture and planning work up to the building application. What such timelines depend on is set out here.
The cost drivers at a glance
The shell of a hall is rarely the most expensive part and rarely the slowest. Schedules tip at the interfaces: when steelwork, facade and building services fail to mesh cleanly, when a foundation has to be reinforced after the fact, or when the building application runs into a loop of follow-up requests.
| Factor | Effect on cost and schedule |
|---|---|
| Layout and standardisation | Recurring axis dimensions and column grids shorten delivery and assembly times because beams and facade elements can be produced in series |
| Facade system | Sandwich panel, curtain wall or masonry set the assembly speed, insulation value and crane time |
| Foundation and subsoil | Load-bearing capacity and groundwater level decide between shallow and deep foundations; a late soil survey costs weeks |
| Industrial floor | Load class, flatness and joint pattern follow the intended use and tie up a lot of pouring and curing time |
| Building services | Heating, ventilation, electrics and sprinklers must be coordinated with the shell early, otherwise change orders pile up |
| Permit | Complete application documents and settled utility connections prevent waiting time at the building authority |
Layout and standardisation
The biggest lever for construction time sits in the layout. Placing the column grid on common axis dimensions and matching the hall width to standard beam lengths saves on structural design, fabrication and assembly. Standardised components can be produced in series and reach the site faster.
Custom requirements are doable, but they cost time exactly where delays propagate. A special column changes the facade division, the facade division shifts the door and window positions. The earlier the layout is fixed, the fewer of these chain reactions occur.
On the two-storey hall for BERTH the time saving came from exactly this. Because we planned the structure and the attached office wing together from the start, the hall could be tendered as a whole and the fabrication of the steel components pushed forward in parallel with the site preparation. Separate planning steps would have cost those weeks.
The facade system sets the pace and the insulation value
The choice of facade acts on three levels at once: assembly speed, energy standard and appearance. Sandwich panels go up quickly and bring the insulation with them. A masonry or monolithic wall is more solid and more durable, but needs more time on site.
For the Diebel haulage company in Wustermark we combined a monolithic shell with a suspended steel facade, plus a flat roof with a large solar array. For the DHL local delivery depot in Königs Wusterhausen we took on project management as well as shell and fit-out work and delivered the building envelope together with our partner SETUP Systembau. Which system fits depends on budget, use and the requirements set by the development plan.
Site logistics hinge on this choice too. Large-format facade elements need crane standing areas and a cleared access route, which on tight sites dictates the sequence of trades. Fixing the facade early lets you bundle the crane days and avoid repeat visits.
Foundation and industrial floor
A lot is decided beneath the hall. Subsoil and groundwater level determine whether a shallow foundation is enough or whether deeper founding is needed. A soil survey belongs at the start, not in the construction phase. If the subsoil only becomes an issue during excavation, the replanning costs weeks.
In industrial construction we design foundations for all load classes. Where machines have to stand to the millimetre, we set embedded parts to an accuracy of up to a tenth of a millimetre. The industrial floor itself is a trade of its own: load class, flatness and joint pattern follow the use, and the pour needs its curing time, which cannot be sped up.
Building services coordination as a schedule risk
Heating, ventilation, electrics and often a sprinkler system have to be thought through together with the shell. Penetrations, routes and connection points belong in the planning before the concrete is placed. Without this coordination, chasing is done afterwards, and days turn into weeks.
In turnkey construction we take on this coordination as the general contractor. On the hall for BERTH in Gallun we aligned the building services and the electrical installation with the other trades, so that shell and fit-out meshed without idle time. This interface work is exactly why the 10 months held. More on our scope of work is set out under Services.
Permit and authority coordination
The building application is the milestone many underestimate. Complete documents and early-settled utility connections, meaning power, water and sewage, prevent waiting time at the building authority. A follow-up request over missing proof pushes back the construction start without a single stone being laid.
For the heating plant on the Funkerberg in Königs Wusterhausen we were responsible for turnkey construction, without the plant technology. Projects like this show how closely permit, utility providers and construction sequence are tied together. We coordinate authorities and utilities from the outset and present a binding construction schedule so the dates hold up.
How to get to a reliable schedule
A realistic time and cost frame comes out of use, layout and subsoil, not out of a price per square metre from the internet. Bring to the first meeting what the hall is being built for: machines, loads, door sizes and the desired move-in date.
For an initial estimate, it helps us most to know:
- planned use: storage, production, workshop or mixed with office
- machine loads and point loads for sizing the industrial floor
- desired door sizes, hall height and access for deliveries
- the site and, if available, a soil survey
- your target date for moving in
Tell us about your project and we will estimate construction time and cost drivers for your specific case. You will find further references at BERTH in Gallun and the DHL delivery depot. For a non-binding first consultation, reach us via Contact.
