Site thermometers should be placed in the shade.

Be visible to all trade persons.

Mortar work can commence at 2°c and rising.

When adverse weather is due, protect the bricks and blocks so they are ready to be used at the start of the day.

DPC taken to the edge of brick work.

Internal leaf DPC overlaps ground floor DPM.

Excess must be cut back from cavity.

Check for damage to the DPM before work commences.

Full bed and perpendicular joints required at all times.

Finish blockwork with bucket handle pointed joints on both sides.

Protect cavity from mortar droppings.

A maximum of 6 courses of block before backing up with external wall.

Ties installed straight and with the drip centred in the cavity.

Ties to be kept free from mortar and debris.

Brick holes filled at the end of every day or before inclement weather.

Brick holes externally fully filled to prevent frost damage.

Engineering bricks used as pad stones, check calcs for strength.

Bricks holes to be filled on engineered brick pad stones for structural strength.

Build in penetration ducting connections as the superstructure progresses.

Verify position from the drawings.

Provide DPM tray and weep holes above the openings.

Ensure blocks are fitted tightly against the joist and pointed neatly.

Cavities are required to be closed off with proprietary cavity barrier.

This needs to be placed at the highest point of external masonry.

Cavity barrier needs to extend under the lintel at openings to the cavity closer.

Cavity barrier to be the correct size for the width of the cavity.

Ensure the cavity is the correct width for the cavity barrier with no gapping.

Cavity barriers continues from the top of the cavity along the pitch of the gable.

Cavity barriers should be carefully formed around right angle corners to ensure continuity.

Cavity barriers to be butt jointed at the corners to ensure no gaps are present.

Cavity barriers at the party wall junction needs to be continuous from foundation.

Ensure cavity barriers is installed as per the manufacturers recommendations.

At the end of every working day brick holes and “frogs” should be filled, brick joints pointed and scaffolds cleared.

All drying brickwork should be protected to prevent frost damage.
