13 SABS 1200 GF-19R4
Concrete (ordinary buildings)
Narrow Widths (the constant width, if in excess of 300 mm, or the range of widths, if up to
300 nun, or width and depth in the case of grooves, will be stated) ..........................
Fillets or splays of size over 20 mm x 20 mm will be measured under this item.
The unit rates shall cover the cost of narrow widths of formwork (including forming fillets
or splays of size up to 20 mm x 20 mm) in contact with the concrete, and the necessary
bearers, struts and other supports plus the labour and plant necessary to erect and strike
such narrow widths of formwork, fillets and splays.
Box-out Holes/Form Voids (Basic dimensions or perimeters or drawing references will be
stated and, for each of (a)-(d) below, an item will be scheduled for the depths given
below.)
1 - Depth, m IFm 1
etc., in increments of 0,5 m
a) Small, circular, of diameter up to 0,35 m ................................................
c) Large, circular, of diameter over 0,35 m and up to 0,7 b) Small, other than circular, of area up to 0,l m2 ..0..,.7. .m. ..................................................................
d) Large, other than circular, of area over 0,l mL and up to 0,s m2 .........................
The unit rates for (a)-(d) above shall cover the cost of all material, labour, plant and
operations necessary to box-out holes or form voids in the concrete, including the cost of
delays to the main formwork program, and wastages in or cutting of the main formwork, or
both.
Reinforcement
a) Steel bars (Type of steel (mild, high-tensile or other) and diameters stated) ............
b) Steel sections (sizes stated) ............................................................
The mass of round and square steel bars of each diameter or side, as relevant, will be
scheduled separately.
In the case of (a) and (b) above the mass measured for payment will be the net mass of all
bars, including supporting steel detailed on the reinforcing schedules. The mass will be
computed from the scheduled length and the nominal mass per unit length for each nominal bar
size. No allowance will be made for cutting, waste, spacer devices (i.e. materials other
than steel bars) or binding wire. I
Separate items will be scheduled for
1) steel to be fixed in different parts of the Works 'where this could materially influence
the pricing of the work; and
2) rails and other steel sections used as reinforcement.
Steel reinforcement for precast and prestressed concrete units will not be measured unless
so scheduled.
Steel offcuts resulting from cutting and bending reinforcement in accordance with the
bending schedule shall be deemed to be the property~ of the Contractor.
The unit rates for (a) and (b) above shall cover the cost of supplying, cutting, bending,
placing in position and fixing of the reinforcing and supporting steel scheduled, and the
cost of providing all spacer devices and binding wire, as well as the cost of tests in terms
of SABS 920.
c) High-tensile welded mesh (Type reference stated) .........................................
The area measured will be that shown on the drawings, no allowance being made for cutting,
waste, laps or deductions for end cover. The areas measured will be those of the concrete
floor or slab reinforced by means of mesh. In the case of continuous units partially
reinforced by mesh, the area will be computed from the outside dimensions of the area
covered by mesh, regardless of the presence or otherwise of additional reinforcing steel
across the same area.
The unit rates shall cover the cost of supplying, cutting and placing of mesh, the cost of
all waste owing to laps, and the cost of providing all spacer devices.
Concrete
It ems
a) Prescribed mix concrete ..................................................................
The proportions and the positions or elements in the Works will be stated.
b) Strength concrete ........................................................................
The grade and the positions or elements in the works will be stated. Except where ordinary
portland cement is required, the type of cement will be stated.
c) Concrete in small quantities, each less than 0,5 m3 of formed concrete ...................
The grade and the positions or elements in the Works will be stated, grouped as to types or
scheduled individually.
d) Subfoundation carpet or blinding layer in .... concrete.
Either of the following will be stated:
-
Minimum thickness and proportions or grade ..................................................
Proportions or grade ........................................................................
e) Concrete abutting against hard rock faces or intermediate excavation, including any
necessary filling to irregularities (no thickness will be stated) (Provisional) .............
Where concrete is to be placed directly against the sides or bottoms or both of excavations
in hard rock or in intermediate excavation, an item may be included in the schedule for any
additional concrete Dlaced in overbreak.
f) Provision and erection of precast (or prestressed) units
1) Provision of precast units (or prestressed units, as applicable) .........................
The dimensions of individual units, and whether reinforcement including prestressing is
included or measured separately, will be stated.
Separate items will be scheduled for different qualities of concrete, different types and
sizes of units, and small units of volume of formed concrete not exceeding 0,s m3.
