Turnkey Factory Construction

With separate trade contracts you sign with the shell, steel, roof, façade, electrical and mechanical suppliers individually and carry the interface risk yourself. Turnkey means one contract, one programme and one company answering for the result. At BIOS the electrical scope sits inside that contract, so the building and the power it carries are engineered together.

We prepare the project files: structural calculations, architectural and electrical drawings, fire and earthing reports. Application, follow-up and responses to municipal or industrial zone comments run through our team.

Steel suits most production halls: faster erection, longer clear spans, easier to extend and easier to hang crane runways from. Precast concrete makes sense for tall storage buildings, heavy fire loads and corrosive environments. We size both and put the cost and programme difference in front of you before you decide.

Yes. Extensions, new bays, mezzanines and foundation work in live production are a regular part of our work. We plan the sequence around your shift pattern, isolate the work area, control dust and noise, and schedule tie-ins for planned shutdowns.

A single-bay steel hall with standard foundations and full electrical infrastructure typically runs 5 to 8 months from approved drawings. Multi-bay plants with heavy machine foundations, a transformer room and process utilities run 10 to 18 months. The critical path is usually set by permit duration and long-lead items rather than the construction itself, chiefly transformers and MV switchgear.

Automotive, home appliances, defense, food, chemicals, energy, metal and mining, paper and packaging. Our deepest experience is in automotive and heavy manufacturing, where the building has to carry press foundations, crane loads and high electrical demand from the first day.

Both. Give us a plot, a production layout and a soil report and we design the structure, the envelope and the electrical infrastructure from scratch. If your architect has already issued drawings, we build to them and review the equipment interfaces: foundation loads, pit dimensions, cable routes and utility connection points.

From the machine drawing and the soil report. Static and dynamic loads, anchor patterns, pit depth, vibration isolation and grout specification all follow the equipment manufacturer's foundation data. Where that data has yet to arrive, we design to the reserved envelope and detail the final anchor layout at a later stage.

Standard industrial floors are laser-screeded and finished to FM2-class tolerance. Narrow-aisle racking, AGV routes and precision machine bases call for tighter values, which we agree in writing before the pour and verify by survey after curing.

Everything from the incoming supply to the machine terminal: transformer room, MV and LV switchgear, main and sub-distribution, busbar and cable tray routes, machine feeds, lighting, earthing, lightning protection and compensation. Control and MCC panels are manufactured in our own workshop and commissioned by the team that built them.

Yes. Scope is set by contract. Common splits are shell and envelope only, shell plus electrical backbone, or full turnkey through to equipment-ready handover. We mark the interfaces clearly, so the following contractor knows exactly where our scope ends.
