Scope and intended use

Aggregates are used in sub-bases, drainage, filling and other construction operations, but these uses do not all require the same material. An enquiry should specify the intended application, the grading or material description required by the project and the estimated quantity. ECOSTA assesses supply and transport arrangements alongside site access and delivery conditions. Confirming the material specification before ordering helps avoid receiving a product that is convenient to deliver but unsuitable for the planned operation.

Details that affect the work

Quantity estimates should state whether they refer to mass, loose volume or compacted volume. These measures are not interchangeable without suitable assumptions. Delivery planning must account for vehicle access, turning space, load restrictions and a safe unloading area. On constrained sites, smaller deliveries may affect the overall logistics. The offer should explain what is included in transport and unloading, and whether spreading or compaction belongs to another work package. Material documentation should follow the requirements of the particular project.

Planning the work package

The first assessment combines your brief with the drawings and information available for the site. We identify access constraints, quantities, interfaces with other trades and the operations that need a technical decision before pricing. The agreed proposal should explain inclusions, exclusions and the basis for measuring the work. A preferred programme is reviewed against the actual sequence, delivery arrangements and any inspections required by the project team. Changes to the initial scope should be described and assessed before they are incorporated into the works.

Preparing your enquiry

Send the municipality, a description of the intended result and any approximate dimensions you already know. Include information about access, neighbouring properties and whether the area will remain occupied or operational. Tell us which plans, studies and specifications are available, and who coordinates the technical design. Photographs can support the initial conversation, but hidden conditions may require additional checks. ECOSTA reviews enquiries in Girona as a priority; projects proposed in southern France require a separate assessment of location, resources and applicable requirements.

Agreeing the handover

Before the work begins, clarify the condition in which the package is to be handed over and which records are required by the project. This may include measured quantities, material information, test results where specified, and instructions relevant to future maintenance. An agreed review helps distinguish completed work from outstanding items and makes interfaces with the next trade understandable. Keeping this information connected to the actual scope gives the owner and technical team a clearer basis for closing the package.
