Procurement information for main contractors.
A practical route for quantity surveyors and site teams to share the package, clarify technical and logistical requirements, and agree what is needed before mobilisation.
What to send at tender stage.
Send the information available rather than waiting for a perfect package. Clear inputs allow the scope, technical basis and programme assumptions to be reviewed properly.
Drawings and schedules
Plans, sections, floor build-ups, BoQ information and relevant NBS or specification clauses.
Areas and depths
Square metres by plot, floor or zone, with nominal depths and changes in build-up identified.
UFH and finishes
Underfloor heating details, intended floor finish and interfaces affecting screed selection or preparation.
Specification
Specified screed system where known, required SR class and any moisture or testing requirements.
Programme
Tender dates, phasing, sequencing, working hours and dependencies with preceding or follow-on trades.
Access and logistics
Delivery position, pump or hose runs, parking, floor access, site restrictions and available work areas.
What is agreed before mobilisation.
Before installation is planned, the reviewed package should establish what is included, what remains outstanding and how the screeding work fits the site programme.
Commercial scope
Written scope, assumptions, exclusions and outstanding information for the package.
Technical basis
Proposed screed system or product where known, build-up, depth and specification-led SR requirement.
Delivery plan
Access, pump or delivery assumptions, working areas, sequencing, phasing and agreed installation dates.
Handover requirements
Curing, drying, UFH commissioning, laitance treatment, moisture testing and follow-on finish requirements for the specified system.
Compliance requirements.
If your procurement process requires specific insurance, accreditation, operative competency, RAMS, COSHH, manufacturer documentation or site forms, include those requirements with the enquiry so they can be confirmed before appointment.
Requirements are checked against the proposed scope and project needs; their inclusion in an enquiry does not itself confirm availability, status or applicability. Tender requirements can also be sent to quotes@screeding.com.
Technical control from specification to handover.
The screed system, build-up, programme and final finish need to be considered as one package rather than as isolated tender lines.
Specification control
BS 8204 guidance and the specified SR class are reviewed in the context of the selected system and intended floor finish.
Floor build-up and UFH
Depth, insulation, membranes, reinforcement where specified, UFH cover and system interfaces are considered together.
Drying and moisture
Drying and readiness remain system- and site-dependent; moisture testing requirements should be identified before sensitive finishes.
Finish compatibility
Preparation requirements, including laitance treatment where relevant, are considered against manufacturer guidance and the final finish.
Send the package for project-specific review.
Use the commercial quotation route for drawings, BoQs, specifications, programme information and tender requirements. The review will identify the appropriate next step.
Common questions.
What should be included with a screeding tender enquiry?
Send the information available, including drawings, BoQ or schedules, relevant specification clauses, floor build-ups and depths, areas by zone or plot, UFH details, intended floor finishes, specified SR requirement, programme, phasing, access and any moisture or testing requirements.
Can procurement requirements be reviewed before appointment?
Yes. Include required insurance, accreditation, operative competency, RAMS, COSHH, manufacturer documentation and site forms with the enquiry so each requirement can be checked and confirmed before appointment. Sending a requirement does not by itself confirm that it is held or applicable.
How are scope and exclusions recorded?
The project-specific quotation sets out the reviewed scope, assumptions, exclusions and outstanding information. Build-up, screed system, depth, access, phasing and handover requirements are recorded where the available tender information allows.
When are installation dates agreed?
Installation dates are agreed against the project programme, site readiness, access, sequencing, materials and the confirmed scope. Phased or sectional works should be identified during tender review so they can be planned with preceding and follow-on trades.
How are BS 8204 and surface regularity requirements handled?
BS 8204 provides relevant code-of-practice guidance for screed work. SR1, SR2 and SR3 are specification-led surface regularity classes, so the required class should be stated in the project specification and reviewed against the screed system and intended floor finish.
What information is needed for screed over underfloor heating?
Provide the floor build-up, insulation, UFH layout, pipe size and spacing, required cover, screed system, commissioning requirements and intended finish. Interfaces and responsibilities should be clear before screed installation is programmed.
Does a screed programme confirm when floor finishes can be laid?
Not by itself. Drying and readiness depend on the screed system, depth, ventilation, temperature, humidity, UFH commissioning and site conditions. Manufacturer guidance and specified moisture testing should inform release for sensitive finishes, while some calcium sulphate systems also require laitance treatment.
