5 Trainer guidance notes Vernacular walling In some areas, vernacular (traditional) walling materials are used in place of either brick or block walling. It is permissible to replace the stated materials with those used in that area. However, it is important to ensure that that training of bricklaying and blocklaying skills are delivered allowing the learners to operate in non-traditional materials. Where vernacular masonry is used, the industrial standard required should be clearly displayed in work areas and on test marking sheets. Industrial standards for practical work Solid walling Setting out, dry bonding bonds to include English, Flemish, English garden wall, Flemish garden wall, in straight lengths, returns and junctions. All walling completed to the following industrial standards/tolerances: Overall wall height should measure within ±5 mm in any 3 m height, with regular joint thickness Walling should be level to within ±3 mm in any 2 m length Walling to be plumb to within ±3 mm in any 1 m height Face plane should not exceed 5 mm in any 3 m length Perpend thickness should be 10 mm with no deviation exceeding 5mm Facework should be clean, with minimal smudging and no visual defects Blockwork Dense concrete blocks, used in a variety of situations, including faced and fair faced: Overall height to be to gauge ±6 mm in 3 m height Walling to be level within a tolerance ±4 mm in 2 m length Walling to be plumb within a tolerance ±4 mm in any 1 m height No face plane deviation more than 6 mm in 3 m length Piers Including detached and attached piers in a variety of situations to masonry walling: Attached piers to be level across pier and wall ±2 mm Distance between attached piers as specified on working drawing/specification Position of detached piers as specified on working drawing/specification Detached piers to be level on all sides ±2 mm Decorative features To include soldier courses, brick-on-edge courses, oversailing courses, copings and capping: Soldier courses Soldier courses to have uniform joints ±2 mm Soldiers to conform to gauge of brickwork ±1 mm Soldiers to be plumb in both directions ±1 mm Soldiers to be clean, with no major defects visible on bricks and match existing walling CC 2047S Page 5 of 6 Version 1 ( )

6 Brick-on-edge course Brick-on-edge course to be level along length (front and back) within a tolerance of ±4 mm in 3 m length Regular joint thickness ±3 mm Horizontal damp-proof course positioned as required on working drawing/specification Quoin blocks or metal cramps positioned as required on working drawing/specification Joint finish to match existing walling or as otherwise specified Facework to be clean, a little smudging permissible, good selection of sound bricks essential Oversailing courses Oversailing course projection to be uniform along length of wall ±3 mm Oversailing courses to be levelled in along eyeline and not tilt forward Cross joints must be full Copings/capping Formed from brick, natural stone, reconstituted stone, concrete, (saddleback, featheredged) local materials, etc. Copings level along length of walling within a tolerance of ±2 mm in full height Regular joint thickness ±3 mm Uniform projection to copings/capping on face and rear of masonry walling ±3 mm Horizontal damp-proof course positioned as required on working drawing/specification Copings to be clean, with only a little smudging allowed Positioning horizontal brick reinforcement Horizontal brick reinforcement positioned as required by working drawing/specification Minimum lap of reinforcement 225 mm on straight lengths and junctions Walling extension provision Extending walling by indents, toothing and proprietary wall connectors Position/type of walling extension provision as required by working drawing/specification Provision for walling extension plumb to within a tolerance ±3 mm in 1 m height Cutting/bedding bricks/blocks to a rake Raking cut to be in line ±3 mm in 1 m Face plane of raking cuts to match existing walling ±2 mm in 1 m length Raking cuts to be at gauge of walling ±1 mm Joint finish To include half-round recessed, internal/external struck, flush, square recessed: Joints full and to all arrises as appropriate Joint finish to extend to all arrises as appropriate Bed joint continuous and uninterrupted CC 2047S Page 6 of 6 Version 1 ( )
