CALYPSO supports project owners, architects, engineering firms, and contractors in the cost estimation, quantity surveying, and economic analysis of tertiary building projects, whether for new construction, renovation, or refurbishment.

Tertiary buildings address specific challenges: space flexibility, quality of use, energy performance, occupant comfort, architectural image, technical constraints, operational timelines, and fit-out cost control. In this context, construction economics helps secure design and cost decisions from the earliest project stages.

Whether for offices, business premises, retail spaces, coworking spaces, administrative buildings, professional floor plates, or mixed-use developments, the objective is to build a clear, coherent, and actionable estimate to support technical and financial decision-making.

CALYPSO specializes in:

quantity take-offs and all-trade quantities;
ratio-based, trade-based or work-item-based estimates;
preparation of bills of quantities and technical specifications;
analysis of technical and economic alternatives;
assessment of interior fit-out costs;
support in arbitrating between architectural quality, energy performance and budget;
integration of life-cycle cost issues, including maintenance, servicing and operation;
monitoring of cost trends based on construction indices.
