Main project
Execution builds on the main project, with a stable base and clear boundaries.
Execution project
Details, specifications, and drawings the contractor needs to prepare and build.
What we deliver
Deliverables, required inputs, and boundaries - one overview in the Scope tab below.
Full scopeWhat we need from you
- Final building permit (or documented agreement on parallel scope).
- Confirmed materials and equipment at agreed checkpoints.
- Named contractor or intent to select contractor (for detail level alignment).
- Cooperation with site supervision and the health and safety coordinator.
Once the permit is under way or final, the contractor needs more than the main project. Execution design helps you reduce improvisation and on-site reinterpretation. We detail the parts of the building that must be precise before construction starts.
Depending on contracted scope, it covers details, material specifications, joints, equipment, and other data the contractor needs. What is drawn here narrows the room for on-site negotiation. Negotiation without a document is cost. This service opens when the next step toward construction is sufficiently clear.
What we deliver
Three views on the same scope: deliverables, your inputs, and what is out of scope.
- Execution architectural drawings (plans, sections, elevations, details).
- Joint, material, and built-in element details at agreed scope.
- Material and equipment specifications (or coordination with interior/joinery).
- Bill of quantities with work descriptions and indicative quantities.
- Revision register per drawing and date of delivery to the contractor.

Duration and rhythm
Typically two to four months after work begins, depending on complexity and design changes during execution detailing.
Scope
- We do not perform construction or manage the site.
- We do not assume liability for contractor deviations from the documentation.
- We do not replace the main project. Execution supplements it; changes that touch the permitted scope are handled as a written addendum.
When we finish this service for you, what is your next step toward a completed project?Legalisation
Delivery of execution documentation to the contractor closes the design package for the standard new-build track. We open legalisation only if as-built deviation or missing documentation of existing stock is identified.
Frequently asked questions
- The contractor and site supervision. Our duty is clear, verifiable documentation.
- Partly, for elements independent of the permit, with written addendum and clear risk split. Standard path is after final building permit.
- Yes, as a separate contract with defined visit intervals and a decision protocol.
- Depending on the change: the designer, supervisor, and/or competent authority.
- Possible with valid licence/rights and a technical compatibility check.
- It increases regulatory and financial risk; changes must be formalised.
- Usually yes, as a separate coordinator elaborate or integrated with architecture.
- Yes, as a separate contract with defined visit cadence and a decision protocol.
- Contract clauses, distribution control, and GDPR where personal data is involved.
Rules and procedures in Croatia
- The execution project is not a permit act; it operationalises the main project for the contractor on site.
- Execution must follow the building-permit conditions; changes touching the permit go through a main-project addendum and permit amendment.
- Detail level is agreed with the contractor at the start of the service; what is not drawn remains room for improvisation and dispute.
- Author statements and authorisations cover liability for the details and specifications each signs.
- Contractor deviations from the execution project are logged in writing and assessed for formal processing.
- The execution project does not replace design supervision, occupational safety, or on-site structural checks.
Execution documentation reduces on-site improvisation, but it does not remove the duty to comply with the permit and construction rules.

Typical site cost drivers.
Late contractor confirmation
Detail level depends on what the contractor actually builds, and the contractor joins late. Drawings stay too thin or get rewritten during construction.
Detail level in the first week
At the start of the execution project we agree who builds and what detail level we expect. A detail plan goes into a written table by discipline.
Material changes without paper
On site a different tile, window, or fitting is agreed without an updated drawing. Later it is hard to prove what was agreed.
Written change record
Every change goes through a short record: what changes, who approves, which drawing version applies. Without approval the work is not treated as agreed.
Unclear responsibility split
Designer, supervisor, and contractor give different instructions to workers on site. The client does not know who owns which decision.
Clear split in contract
We write the split of work in contracts and repeat it in weekly updates. Site communication goes through agreed channels, not ad hoc.
Late sample approval
Tiles, colours, or equipment wait for client sign-off while contractor due dates run. Construction stops or goes to storage and extra cost.
Checkpoints with due dates
The sample and decision plan has due dates and a named person on the client side. Delays are logged and escalated in writing.
What we need for a calm execution project.
- Final building permit or a documented parallel scope.
- Named or planned contractor.
- Material and equipment specifications at agreed checkpoints.
- Supervision and safety-coordinator contracting plan.
- Readiness for timely sample decisions.
A missing document does not block the first conversation. Tell us what you have, what is missing, and what you want to reconstruct.
Where execution design sits among the stages
Execution design links permit and site. With it, construction is measured and controlled. Clear documentation narrows the room for interpretation.

Execution project
·
Site execution
The contractor builds from execution drawings; documentation keeps decisions within the frame.
·
Site supervision
Supervision measures the situation against the execution documentation.
·
Small repetitive interventions
In some cases the main project alone is enough, but the risk of improvisation grows.
Execution design does not change the building permit. Any change touching the permitted scope is handled as a written addendum.
Standards we work to
The execution project demands the strictest coordination of details, materials, and tolerances. What is resolved on paper avoids costly decisions on site.
Manufacturing/construction information, coordinated technical release.
Contractor detailing and support during execution.
Issue for construction: controlled release and revisions.
Field changes logged, assessed, approved.
