Tendering a warehouse floor isn’t just about getting the cheapest quote; it’s about making sure every contractor is pricing the same specification. Without detailed information, you risk wide price differences, missed scope items, and disputes once work begins.
A well-written tender ensures accurate pricing, better programme planning, and fewer on-site surprises. This guide outlines the most important details to include in your warehouse flooring tender, whether you're building from scratch or upgrading an existing slab.
Clearly state the required slab thickness (e.g. 200 mm), type of concrete (e.g. C35 with steel fibres), and reinforcement (e.g. A252 mesh or fibre dosage). If not yet designed, request pricing for options. Be specific about joint layout, armoured joint requirements, and slab zones (e.g. forklift lanes vs storage). This helps contractors accurately estimate materials, delivery, and installation labour without assumptions.
Include what type of sub-base is needed (e.g. 150 mm MOT Type 1 compacted in layers), whether the contractor is responsible for excavation or just blinding, and what base tolerances are required. Note any soft spots, soil reports, or level changes. Ground prep affects the slab’s long-term performance and cost; don’t leave it vague.
Specify whether you require a power float finish, polished concrete, or a resin coating system. Define floor flatness/levelness requirements (e.g. FM2, SR2). If slip resistance is important, include the desired PTV rating or texture. Make sure the finish spec matches your intended use; forklifts, racking, or foot traffic each need different properties.
Contractors need to know how materials and plant will access the site. Include details on access points, loading limits, working hours (day/night), and storage/staging space. If other trades will be active or phased handovers are required, make that clear. Any restrictions on water, power, or lighting also need to be specified. These factors can change crew size and programme duration.
Outline your target start and completion dates. If the flooring works are part of a critical path, say so. Specify if the slab needs time to cure before follow-on trades or machinery install. If you’re applying coatings or polish, clarify when those can take place relative to concrete placement. Programme certainty helps contractors allocate labour and price accurately.
Include whether you require third-party testing for compressive strength, slip resistance, or flatness. Note handover documentation expectations such as pour records, curing logs, and warranty information. If inspections will be staged (e.g. after prep, post-pour, final finish), that should be included too. This helps prevent disputes and ensures the floor meets spec before sign-off.
If you’re undecided between polish or coating, include both as line items. If you need removal of an old floor slab or resin system, add this as a separate option. This helps you compare costs directly and avoids confusion or omissions. Make it clear what is required vs optional to allow proper quote structuring.
