ACCURACY: Notwithstanding clause 520, comply with any critical dimensions given in Preliminaries Section A33 / 321-380, on the drawings, or as required by following trades.

545 · · ·

LEVELLING OF SEPARATE LEAVES: Bring both leaves of cavity walls to the same level at: Every course containing vertical twist type ties or other rigid ties Every third tie course for double triangle/butterfly ties Courses in which lintels are to be bedded.

560

COURSING BRICKWORK: Gauge brick courses four to 300 mm including joints.

595

LINTEL BEARINGS: Carefully predetermine setting out to ensure that full length masonry units occur below lintel ends.

635

JOINTING: When not specified otherwise, finish joints neatly to the specified profile(s) as the work proceeds.

645

UNEXPOSED JOINTS: As the work proceeds, strike off joints that will not be exposed to view in the finished work.

665

POINTING: Where specified, rake out joints to a depth of 12-15 mm as the work proceeds. Subsequently, remove loose debris from the joints using a dry brush, dampen the work, and neatly point to the specified profile in a continuous operation from the top of the wall downwards as the scaffolding is taken down.

670

FIRE STOPPING: Fill joints around joist ends built into cavity walls with mortar to seal cavities from interior of building.

671

FIRE STOPPING: Ensure a tight fit between brickwork and cavity barriers to prevent fire and smoke penetration.

ADDITIONAL REQUIREMENTS FOR FACEWORK 710

THE TERM FACEWORK, where used in this specification, applies to all brick/block walls finished fair. Where any facework is to be painted, the only specification requirement to be waived is that relating to colour.

740

REFERENCE PANEL(S): Prepare panel(s) as set out below and, after drying out, obtain approval of appearance before proceeding. Construct panels in an approved location using randomly sampled bricks/blocks but rejecting any that are damaged. Walling type F10/ 250 GENERAL Size of panel: 1000 x1000mm Including example of joint, lintel, and top of wall

·

750 · · ·

760 · · · · ·

COLOUR MIXING: Agree with manufacturer and CA methods for ensuring that the supply of facing bricks/blocks is of a consistent, even colour range, batch to batch and within batches. Check each delivery for consistency of appearance with previous deliveries and with approved samples or reference panels; do not use if variation is excessive. Mix units from different packs and deliveries which vary in colour to avoid patches, horizontal stripes and racking back marks in the finished work. APPEARANCE: Select bricks/blocks with unchipped arrises. Cut with a masonry saw where cut edges will be exposed to view. Set out and lay bricks to match appearance of relevant approved reference panel(s). Keep courses evenly spaced using gauge rods. Set out carefully to ensure satisfactory junctions and joints with adjoining or built-in elements and components. Complete each lift in one period of operation. Protect facework against damage and disfigurement during the course of the works, particularly arrises of openings and corners.

780

GROUND LEVEL: Facework to start not less than 150 mm below finished level of external paving or soil except where shown otherwise.

790

PUTLOG SCAFFOLDING to facework will not be permitted.

830

CLEANLINESS: Keep facework clean during construction and thereafter until Practical Completion. Turn back scaffold boards at night and during heavy rain. If, despite precautions, mortar marks are deposited on the face of masonry units, leave to dry then remove with a stiff brush. Rubbing to remove marks or stains will not be permitted.

COMPACTION OF SCREEDS: Compact proprietary screeds using methods recommended by the manufacturer. Compact other screeds as follows: Compact screed layer(s) thoroughly by mechanical means (e.g. plate vibrator) or, where this is not practicable, by hand using a handrammer or weighted roller. Lay screeds over 50 mm thick in two layers of approximately equal thickness. Roughen the surface of the compacted lower layer and immediately lay the upper layer. CRACK CONTROL REINFORCEMENT: Type: Steel Fabric A393 to BS 4483. Place between the two layers of screed, lap edges not less than 100 mm and tie securely with steel wire. Ensure continuity through daywork joints. Where necessary arrange reinforcement to avoid a four layer build up at corners. HEATED SCREEDS: Collaborate with the services subcontractor to ensure that screed bays are properly coordinated with the heating circuits and that all technical requirements are satisfied. Ensure that the heating elements are properly secured to prevent displacement whilst the screed is laid. Lay screed carefully ensuring thorough compaction around the heating elements without damaging them. Ensure that recommendations for curing and controlled heating of screed are followed.

FINISHING/CURING 510

TIMING: Carry out all finishing operations at optimum times in relation to the setting and hardening of the material. Do not wet surfaces to assist surface working. Do not sprinkle cement onto surface.

530

SMOOTH FLOATED FINISH: Use a hand float, skip float or power float to give an even surface with no ridges or steps.

540 · ·

TROWELLED FINISH to receive applied floor finishes: Float to an even surface with no ridges or steps. Hand or power trowel to give a uniform smooth but not polished surface free from trowel marks and other blemishes, and suitable to receive the specified flooring material. If, because of inadequate finishing or protection, the surface of the screed is not suitable to receive the specified flooring material, it must be made good by application of a smoothing compound by and to the satisfaction of the flooring subcontractor. Allow for the cost of any such making good.

·

660

PROTECTION: Adequately protect screeds/toppings from damage and contamination by subsequent building operations.
