Excavation and site preparation prices in Istria
The supplied Tecton rate for machine-and-manual foundation excavation is €45/m³, and the 0/32 aggregate sub-base item is €40/m³, excluding VAT. The actual quote must clarify ground conditions, access, disposal and the precise supply and installation scope. Indicative prices excluding VAT; the final price is confirmed after a site inspection and preparation of an itemised bill of quantities.

What does a foundation excavation item describe?
A foundation excavation item needs a reference to the design, measured volume and site assumptions. The shape and depth of the excavation come from the project rather than a general construction guide. Clarify the intended working space and how quantities will be verified. The quoted description should also explain which operations are included and where the item ends. An excavation rate is not automatically a complete site-preparation package, just as removing material does not by itself establish that the ground is ready for every subsequent construction operation.
How should the excavated volume be measured?
Use a defined measurement basis tied to the project and the agreed site records. A volume measured in place should not be confused with an unqualified loose volume after excavation or a transport count. The bill of quantities should identify the unit and the boundaries of the measured work. Where the actual conditions require a change from the planned excavation, document the reason and the proposed quantity before treating it as an agreed addition. A consistent measurement method makes later checking more straightforward for both the investor and contractor.
Why do ground conditions and existing structures matter?
Ground conditions cannot be confirmed from the town name or from the fact that a plot is in Istria. The relevant design and site assessment should establish the appropriate excavation approach and any implications for nearby structures or services. If an unexpected condition is exposed, it needs review before work simply continues on the original assumption. This guide does not classify a specific plot or promise one price for every possible material. The offer should state the ground assumptions that support its rate and the process for resolving a different finding.
Is removing excavated material included?
Confirm whether material stays on the plot, is reused in a specified way or must be transported away. Loading, transport, lawful disposal arrangements and any restrictions on temporary storage should be described in the quotation. These responsibilities can materially change the scope even when the excavation volume remains the same. Do not assume that a foundation excavation item includes every movement of the excavated material. If reuse is planned, the material’s suitability for the proposed purpose needs the appropriate assessment; convenience alone does not establish that it is suitable backfill.
What is included in the sub-base item?
The supplied 0/32 aggregate sub-base rate is €40/m³ before VAT. Confirm supply, transport, installation, the measurement basis and compaction requirements in the project-specific offer. Indicative prices excluding VAT; the final price is confirmed after a site inspection and preparation of an itemised bill of quantities.
The specified grading is only part of the item. The intended location, thickness and finished level should follow the project, together with the preparation of the supporting surface. Clarify how the installed work is checked and which records are required before the next layer is placed. A delivered loose volume and a measured completed layer may be different quantity bases. An itemised quotation should make that distinction visible instead of leaving it to interpretation after material has arrived on site.
How do access and logistics change the works?
Consider the route for machinery, delivery vehicles and removal of excavated material. Gates, slopes, overhead obstructions, neighbouring buildings and limited turning or storage space can affect the method and sequence. The location of services should be established through the appropriate project process before excavation. Photographs are useful for the initial discussion, but the site conditions still need review. Any temporary access or protection work should be described separately where it is outside the excavation item, so that the offer reflects how work can actually be carried out on the plot.
What needs to be coordinated before the next construction stage?
Excavation, levels, foundations, drainage and planned service routes need to be coordinated with the current drawings. The agreement should identify the required inspection or acceptance before work is concealed by subsequent layers. If levels or dimensions change, confirm the effect on quantities and adjoining construction rather than relying on an informal instruction alone. Payment and variation procedures should match the agreed measurement method. A clear record of completed work helps the next operation start from a defined condition and avoids uncertainty about which party was responsible for an unresolved interface.
What should be sent for an excavation assessment?
Send the plot location, available plans and sections, proposed levels and the relevant bill of quantities. Include photographs of the route into the site and identify any known existing structures or services. State whether the enquiry concerns foundation excavation, broader site preparation or external works such as access routes. Tecton offers excavation and external works in Istria. A useful assessment should distinguish the designed excavation, material handling, sub-base and other preparations, so the eventual offer does not conceal several different operations behind one generic rate.
Which services, locations and projects should you explore?
What else should you clarify before starting?
Does the excavation rate include every type of ground?
No universal ground classification is established by this guide. The quotation should state the assumed conditions and how a different finding will be assessed. Use the project’s technical information and the site inspection to define the actual scope.
Is spoil removal automatically included?
Do not assume so. Confirm loading, transport, temporary storage and disposal responsibilities in the offer. If material will stay or be reused, describe where and for what specified purpose.
Is loose material volume the same as completed sub-base volume?
They are different measurement concepts. The quote should identify the agreed quantity basis for supply and for installed work. Use the specified completed levels and requirements rather than converting between them with an assumed factor.
Can excavation be quoted without a project?
An initial enquiry can identify the intended work and missing information. A precise foundation scope needs the relevant drawings, levels and site assumptions. A generic plot area is not enough to establish the excavation volume.
Does site preparation include a driveway?
Only if it is expressly listed. Foundation excavation, temporary construction access, permanent access routes and finished external paving are different scopes. Ask for separate descriptions and quantities where those works are required.
What should I send to request an initial assessment?
Provide the location, drawings if available, photographs of access and a short explanation of the proposed work. State what should happen to excavated material and identify known site constraints so the next review can focus on the missing quantities and responsibilities.
How can you request a free initial assessment?
Send the location, scope and approximate area. A detailed bill of quantities and final quotation depend on documents and a site review; the scope of that work is agreed separately.
