INSIDE THE PRODUCTION PROCESS

Factory & Production

Follow the work behind the finished stone: slab cutting, profile checks, carved details, trial fitting and split-face processing. Different products pass through different operations; the drawings and approved selection connect them.

01 / SLAB CUTTING

Start with the selected slab.

The cutting stage connects the approved material to the dimensions and pattern direction on the drawing. Review the visible faces and adjoining pieces before the next operation.

02 / PRODUCTION

Check the profile by hand

A square and marking pencil bring the carved surface back to the intended profile. Check recesses, edges and transitions while the piece is still on the bench, before the final finish.

03 / PRODUCTION

From tool path to carved detail

Machine shaping establishes the relief, followed by refinement of the carved details. Review relief depth, edge definition and the allowance for hand finishing before approving the final piece.

04 / PRODUCTION

Check how the parts meet

Trial fitting the table base to the underside of the top makes the interfaces visible. Coordinate connection positions, support and handling before the assembly is prepared for packing.

05 / PRODUCTION

Develop a natural split face

Splitting brings out a natural relief for walling and landscape stone. Review the face depth, size range and edge character against the intended installation.

01 / Sourcing

Material sourcing.

Start with the application, design reference and preferred material character. Review proposed selections with current photographs and the information needed for your decision.

Natural variation is part of the process. Confirm the actual selection rather than assuming that reference images represent an identical future batch.

For the selection record, identify each proposed slab or block in the photographs and list the intended pieces beside it. Record the finish reference and any agreed variation range so later reviews refer to the same selection.

02 / Drawings

Engineering & drawings.

Our drafting support brings dimensions, visible faces, junctions, edge details and finishes into reviewable stone drawings. We help develop the fabrication details with your project team and identify interfaces that require the designer, contractor or installer's input.

Link drawing revisions to the item codes and quantities in the stone schedule. Identify the approval owner, site measurements still required and any first-piece or sample-room review. Record changes before they become production assumptions.

Agree a drawing review format: dimensioned PDF sheets or annotated images for comments, with CAD files where needed for the agreed scope. Keep the revision, item code and approval status visible; a marked-up reference image should not be mistaken for a released production drawing.

03 / Fabrication

Stone fabrication.

Coordinate cutting, shaping, finishing and assembly around the approved design. The method depends on the stone, geometry and construction requirements.

For repeat products, review a first piece before the wider batch. For custom forms, resolve the edge, bowl, curve or mitred junction with close-up photographs and the agreed drawing. Group progress records by item code so a project team can review the right piece.

04 / Dry lay

Dry lay & vein matching.

For suitable multi-piece arrangements, discuss dry lay and vein review before packing. This allows the layout and visual relationship of pieces to be considered together.

View the arrangement across the full area and at the joints. Linear stone can change character when panels are rotated, while a small sample cannot show the overall rhythm. The workshop record below shows a drawing being reviewed alongside the laid-out stone pieces.

Plan which surfaces should read together: a lobby floor, adjoining wall panels, a stair flight or the visible faces of a counter. Review a numbered layout against the approved drawing and identify adjustments before the pieces are packed.

05 / Quality

Quality inspection.

Set out the checks and records your project needs: selected material, dimensions, finish, fittings and packing. Use the approved drawing revision and agreed tolerances as the inspection reference. Review overall dimensions alongside close views of exposed edges, corners, bowl openings and joints; identify any required correction before release.

Details to review
  • Selection record: identified slab or block photographs, linked to the proposed pieces and finish reference
  • Drawing review: annotated or dimensioned sheets showing revision, item codes, openings, visible faces and agreed tolerances
  • Dimensional record: measurement photographs linked to the piece and the drawing dimension being checked
  • Surface review: close-up photographs of agreed edges, corners, bowl openings and joints, with any correction noted
  • Layout record: numbered dry-lay photographs linked to the drawing for the multi-piece areas included in the scope
  • Dispatch record: packing photographs and a packing list connecting crate IDs, piece codes, quantities, package dimensions and gross weights

06 / Packing

Packing for the confirmed piece.

Review protection, support, identification and handling requirements around the product. Share destination access or unloading constraints before the packing plan is finalised.

Agree a crate and piece-identification system that relates to the packing list and project areas. Review lining and support, package dimensions, gross weight and unloading arrangements before dispatch. For staged projects, define the shipment groups and spare pieces.

Agree which records the destination team needs and their format, such as a packing-list spreadsheet or PDF with the corresponding crate photographs. Keep the list and photographs together by crate ID so the team can locate an item without relying on the appearance of the outer packaging.

07 / Delivery

International delivery coordination.

Coordinate production readiness, packing and shipment requirements with the agreed scope and destination. Keep responsibilities visible so that the project team can plan the next step.

Discuss EXW, FCA, FOB, CIF, DAP or DDP around your destination and supply scope. Confirm the available delivery term, named place and responsibilities in the quotation.

Use the packing list to connect each package with its contents and delivery stage. Agree which loading views, crate identifiers and shipping records should be shared. The photograph below records crated stone and timber bracing inside a container; the loading arrangement for a new shipment must be planned around its actual cargo.
