How We Work

From the first conversation to commissioning.

Every project follows five clearly defined phases. At every stage you know which service is being delivered, which decision is pending and what result is in hand.

  1. 01

    Analysis & requirements

    Initial discussion, on-site assessment of the existing situation, review of available documents and consumption data. We clarify usage, objectives, boundary conditions and schedule. The initial discussion and on-site assessment are free of charge and non-binding.

    Result: Requirements profile, objectives, indicative timeline

  2. 02

    Concept & variants

    Technology-open system comparison — heat pump, district heating, wood, gas or hybrid, plus ventilation and cooling concepts. Complemented by a rough cost estimate based on experience values and a life-cycle cost assessment.

    Result: Comparison of variants, rough cost estimate, recommendation

  3. 03

    Design & sizing

    Building and execution design, calculations and sizing, coordination with architects and other specialist planners — fully model-based in Trimble Nova.

    Result: Design stages, calculations, coordinated model

  4. 04

    Tendering & procurement

    Model-based bills of quantities with traceable quantities, tender review, comparison matrix and award recommendation. No manufacturer bias, no reserve items.

    Result: Bill of quantities, tender comparison, award recommendation

  5. 05

    Realisation & commissioning

    Specialist site supervision within the commissioned scope, monitoring of execution, acceptance inspections, commissioning adjustments and handover of documentation to the client.

    Result: Acceptance records, commissioning adjustments, documentation

Principles in every phase.

100% in-house

All fee-based design services are delivered in our own office — no outsourcing, one point of responsibility.

Model-based

Consistent data, coordinated design stages and traceable quantities from a single model.

Technology-open

No manufacturer ties. Decisions are based on requirements, building fabric and cost-effectiveness.

Transparent

Assumptions, cost derivations and fees are documented — no hidden costs.
