Laboratory Worktop RFQ Checklist: Drawings, Cutouts, Edges, and Joints

Prepare a comparable laboratory worktop RFQ with controlled drawings, cutout schedules, edge and joint details, equipment loads and clear supplier responsibilities.

A laboratory worktop RFQ should do more than list a material, thickness and total length. Suppliers need enough information to review drawings, support conditions, equipment loads, sinks, service cutouts, edges, joints, delivery and installation scope. Without those details, two quotations may appear comparable while covering different assumptions.

Use this laboratory worktop RFQ checklist to prepare a clearer enquiry package before requesting prices. If the material decision is still open, first review the epoxy versus phenolic worktop exposure process. The RFQ should then identify the proposed material or state which exposure information the supplier must review.

Start With a Controlled Drawing Set

The drawing is the main reference for dimensions, quantities and interfaces. Give every issued drawing a title, number, revision and date. If several files describe the same bench, identify which document controls when dimensions conflict.

Show room, elevation and worktop views

Provide a room plan or bench layout that shows the location and orientation of each worktop. Add elevations or sections where wall conditions, equipment clearances, support frames or raised edges cannot be understood from the plan alone.

Mark the units used and distinguish finished dimensions from nominal planning dimensions. If dimensions remain subject to a final site survey, state who will measure, when the survey can occur and which party approves the final fabrication drawing.

Use identifiers that connect drawings and schedules

Assign a unique reference to each worktop or repeated type. Use the same reference in the drawing, quantity schedule, sink schedule and quotation request. This reduces the risk of one cutout or edge detail being applied to the wrong bench.

Record revision ownership

State who may issue a drawing revision and how changes will be acknowledged. A late change to a sink, tap or instrument opening can affect material use, fabrication time, support requirements and delivery. The RFQ should require the quotation to identify the drawing revision on which it is based.

Define Worktop Material and Exposure Information

Identify the requested worktop material, finish, color and proposed thickness where these decisions have been approved. If alternatives are permitted, ask the supplier to name the exact proposed option rather than quoting a generic material family.

Attach the relevant exposure information: chemicals, working concentrations, contact duration, heat sources, cleaning agents, cleaning frequency, wet areas and equipment loads. The quotation should state what information was reviewed and which conditions still require confirmation.

The available laboratory worktops category can help define the material families that may need discussion, but a category page does not replace project-specific evidence or an approved specification.

Schedule Every Cutout and Penetration

Do not describe openings only as “sink cutout” or “service hole.” Each opening should be tied to an approved component, dimensioned from stable reference points and assigned to a responsible party.

Sinks, taps and drainage interfaces

For each sink, identify the basin model or approved dimensions, mounting approach, rim or joint detail, tap locations, drainage route and access required for installation and maintenance. Show whether backsplashes, raised edges or drip-control details affect the sink position.

If an integrated sink or formed detail is being considered, keep the requirement provisional until the material, fabrication method and final drawing have been reviewed. Do not assume that one sink detail can be produced in every worktop material or thickness.

Equipment and service openings

List openings for instruments, monitor arms, electrical fittings, gas or water fixtures, data points and other services. Include the component reference, opening size, tolerance, edge distance and any removable cover or access requirement.

Confirm whether equipment suppliers have issued final templates. Where a template is not available, identify the opening as pending rather than allowing an estimated dimension to become a fabrication instruction.

Factory versus site fabrication

Ask the quotation to separate factory-prepared openings from approved site work. Record who supplies templates, who confirms the location, who protects the surrounding area and who accepts the finished opening. Site cutting should not be assumed to be suitable for every material, opening or installation condition.

Specify Edges, Backsplashes and Wall Interfaces

Edge requirements affect appearance, cleaning, wet-area control and fabrication scope. Mark the edge condition on every exposed side rather than using one general note for the complete project.

  • Identify exposed front and side edges.
  • Show wall-side edges, upstands or backsplashes.
  • Define outside and inside corner conditions.
  • Record sink-edge and service-opening treatments.
  • State the required finish at field joints and removable sections.

Walls are rarely perfectly straight. The RFQ should explain whether the worktop will be fabricated from design dimensions, verified site dimensions or an approved template. It should also identify who is responsible for gaps, scribes, sealant and wall finishes outside the worktop supply.

Place Joints With Installation and Use in Mind

Panel size, access routes and room geometry may require joints. Their location should be reviewed before quotation, not decided only when material reaches the site.

Avoid placing a joint without reviewing nearby sinks, concentrated equipment loads, support points, cleaning zones and service openings. Ask the supplier to show proposed joint positions on the fabrication drawing and describe the applicable preparation, support and sealing scope for the offered system.

If a long worktop must be divided for transport, confirm the largest section that can pass through doors, corridors, lifts and final room access. Record who checks the route and whether packaging changes the required clearance.

Describe Support and Equipment Loads

Provide the bench-frame or cabinet arrangement below the worktop. Show support points, spans, cantilevers and areas interrupted by sinks or service access. List heavy equipment with its weight, footprint, support locations and any vibration or leveling requirement.

The supplier or project designer should review the proposed construction as a complete assembly. A worktop thickness should not be accepted as proof that every span, load or large cutout is suitable.

Use a Comparable RFQ Schedule

A structured schedule helps the project team compare inclusions, exclusions and open decisions across quotations.

RFQ item Information to issue Supplier response requested
Drawing control Drawing numbers, revisions, dates and worktop references Revision used for the quotation and list of missing information
Material Material, finish, color, thickness and exposure list Exact proposed option, current evidence boundary and limitations
Cutouts Component references, dimensions, locations and templates Factory/site scope, tolerances and approval requirements
Edges and upstands Edge types by side, corners, backsplashes and wet-area details Fabrication detail and items excluded from supply
Joints Preferred locations, access restrictions and nearby equipment Proposed joint positions, support and sealing scope
Support and loads Frames, cabinets, spans, equipment weight and support points Required support arrangement and unresolved design conditions
Delivery and installation Access route, site readiness, working hours and storage limits Packaging, delivery, installation, protection and handover scope

Separate Supply, Installation and Site Responsibilities

Ask each quotation to state whether it includes final measurement, fabrication drawings, samples, worktop supply, delivery, unloading, lifting, installation, jointing, sealing, protection and waste removal. Also identify responsibilities for sinks, taps, fixtures, service connections and making good adjacent finishes.

Record the approval sequence. A practical sequence may include material and color approval, verified dimensions, coordinated cutout information, fabrication drawing approval and release to production. The exact sequence depends on the project and supplier scope, but it should be visible before an order is placed.

Review Quotations Against the Same Assumptions

When quotations arrive, compare the exact material offered, drawing revision, quantities, cutouts, edge details, joints, support assumptions, delivery and installation scope. Do not compare only the total price.

Create an open-items list for missing dimensions, unapproved equipment, provisional sink details and excluded site work. Resolve material differences with current technical information rather than treating the lowest or highest price as evidence of suitability.

Prepare the RFQ Package for Private Project Review

Before sending the enquiry, confirm that the package contains:

  1. A controlled room or bench drawing set.
  2. A worktop schedule with identifiers, dimensions and quantities.
  3. The proposed material, finish, thickness and exposure information.
  4. Sink, tap, fixture, equipment and service-opening details.
  5. Edge, backsplash, corner, joint and wall-interface requirements.
  6. Support conditions and equipment loads.
  7. Delivery-route, installation and site-readiness information.
  8. A responsibility and exclusions schedule.

Then send the worktop RFQ drawings for private project review. Drawings and project documents submitted for review are handled privately and are not published on the website.

Frequently Asked Questions

What drawings are needed for a laboratory worktop quotation?

Provide a room or bench plan, worktop dimensions, elevations or sections where needed, support conditions, sink and service locations, edge details and a revision-controlled schedule. The required drawing set depends on the project interfaces.

Who should confirm laboratory worktop cutout dimensions?

The RFQ should name the party responsible for the component template, final dimensions, location approval and fabrication release. Do not rely on an unapproved catalogue dimension when the exact supplied component may change.

Should worktop joints be shown before ordering?

Yes. Proposed joint positions should be reviewed against panel size, access, support, sinks, equipment and cleaning requirements before fabrication drawings are approved.

Can cutouts be completed on site?

Site fabrication depends on the exact material, opening, tools, access, support and supplier or installer scope. The permitted work and responsibility should be confirmed in the approved drawings and quotation.

How can two laboratory worktop quotations be compared?

Compare the offered material, drawing revision, quantities, cutouts, edges, joints, support assumptions, samples, delivery, installation, exclusions and open decisions. A total price alone does not show whether the quotations cover the same scope.
