Concrete work: compare quotes and prices

Separate installation and material supply

Concrete work may include formwork, reinforcement, placing, compaction and curing. Supply alone does not automatically include these tasks. A partial commission, such as formwork or reinforcement to existing drawings, must also be distinguished from complete construction.

A slab may have a structural role; screed or later flooring serve different purposes. Existing damage may require specialist concrete repair. Identify new work, an addition or replacement without equating supply, surface care and a structural intervention.

Describe use and exposure

A basement floor, trafficked area, suspended slab and plinth have different requirements. Indoor, outdoor or existing-building work affects design and construction. Describe later use without selecting strength, exposure or reinforcement classes.

Structural elements and construction connections require loads and interfaces professionally designed. Even a small element can face relevant forces. Size alone does not prove simplicity, exemption from permission or an insignificant structural role. Clarify available design and who resolves outstanding technical points.

Coordinate dimensions, levels and embedded parts

Known length, width, height or thickness help the initial assessment. For several elements, describe known details together. This is not a final construction drawing. Position, connections, openings, falls and levels need agreement before placing.

For stairs, columns and special shapes, total area often is not enough. Intended usable area does not define all formwork or concrete quantities either. Give known models or connection details. Final dimensions and material quantities follow the intended construction.

A prepared site means more than empty space

Before concreting, substrate, formwork, reinforcement and embedded parts must be ready in the agreed condition. Responsibility for these tasks and checks is an important interface. The contractor needs to know about owner clearing or prepared excavation; that does not itself prove suitability.

Existing paving, components to remove or connections to existing structures can add work. Material routes, protection of adjoining areas and working space need coordination. Easy road access does not establish that concrete can reach the actual placing point.

Agree the intended finish before construction

A later-covered surface, directly used floor and exposed concrete are different aims. Identify use and appearance early. Consistent appearance, joints, edges and texture need more detailed agreement; smooth alone does not define every requirement.

For exposed concrete, suitable references or samples help align expectations and feasibility. Small hand samples and completed reference elements are different. A young surface’s colour and effect can still change. Discuss observations against agreed requirements rather than treating every natural variation as defective or always acceptable.

Include curing and total costs

Concrete develops properties through hardening; simply drying is not the aim. Temperature, wind, moisture and the element affect protection and development. Winter work is not automatically impossible but needs suitable preparation. The contractor determines curing, formwork removal, support and later loading. A universal watering recipe or calendar day does not suit every element.

Compare design, preparation, formwork, reinforcement, concrete, placing and agreed finish together. Small quantities, difficult routes, several stages and protection can add costs. A plant price per cubic metre is not an installed-element price. Quantity basis, transport, additional work and VAT belong explicitly in the comparison.

Details for a quick enquiry

• Element. Identify floor, wall, slab, stairs or another project.
• Scope. Separate full construction from a clear partial task.
• Known details. Add measurements and available interface information.
• Access. Give floor, route and visible obstacles.
• Result. Clarify later use and intended finish.

From the project to coordinated handover

An initial enquiry may leave technical details open. Before construction, necessary documents, interfaces and checks are clarified. Agree who protects the young element until further use and when subsequent work can begin.

1. Make the enquiry. Describe element, task, known dimensions and timing.
2. Agree preparation. Coordinate drawings, existing work, construction and access.
3. Compare quotes. Consider matching tasks, finish and curing.
4. Hand over. Clarify recorded work, outstanding items and use date.
