ACTIONVERIFY
.5Preparation of Work, Materials and Components:i)When the
materials and components are distributed to the work area, ensure
that the structure is not overloaded.ii)Plan for scaffolding
material required for work at heights. Plan for additional manpower
for lifting blocks at heights.iii)Set out anticipating the position
of openings etc. in the work above to avoid adjustment of units
leading to incorrect or uneven bonding..6Preparation of Mortar
Mixes:
i)Mortar shall be mixed by machine except for small quantities
only. Hand mixing (if permitted) may be done on a watertight
platform.ii)When mixed at site, batch boxes shall be used to ensure
correct and consistent mix proportions.iii)Use mortars (other than
retarded mortars) within 2 hours of mixing or as
specified..7Building walls:i)Build work within permissible
deviations as specified.ii)Unless otherwise specified/permitted,
lay blocks on a full bed of mortar and fill all joints. Place
reinforcement as detailed in position, use spaces as necessary to
keep courses levelled and perpend vertically aligned. Plumb quoins
and all faces as the work proceeds. It is preferable to align
vertically every fifth or sixth perpend and `even out the size of
intermediate joints. Try to keep horizontal joints of uniform
thickness.iii)Do not carry one course more than the height
specified in the contract specifications. iv)Where pointing is
specified rake out joints as work proceeds. The mortar used for the
pointing should be mixed as detailed in the specification.v)All
work shall be bonded to adjacent structures by means of stainless
steel cramps at specified spacing unless specified otherwise.vi)All
glass blocks must be cleaned down as work proceeds.
