94.1(2)An employer shall ensure that formwork and shoring are designed by an engineer and are erected in accordance with design drawings prepared by the engineer.
94.1(3)An employer shall ensure that the design drawings referred to in subsection (2)
(a)
identify the components, if manufactured formwork and shoring are used,
(b)
show the size, grade and specifications of materials to be used, if the formwork and shoring are to be constructed on the project site,
(c)
show the design loads for the formwork and shoring and detail the bracing and external ties required to adequately support the design loads,
(d)
show the attachment points for rigging and hoisting, if the formwork and shoring are to be moved as a unit,
(e)
set out the erection instructions specified by the manufacturer or the engineer,
(f)
indicate the method, the sequence and the rate of pouring concrete, and
(g)
bear the signature and seal of the engineer.

(a)
are kept on the project site, and
(b)
are made available to an officer on request.
94.1(5)An employer shall ensure that the formwork and shoring are erected, supported and braced so that they are capable of withstanding all loads and forces likely to be applied to them
(a)
without exceeding the allowable working loads established for any component of the structure, and
(b)
without causing uplifting, sliding, overturning or lateral displacement of the system.
94.1(6)The allowable working loads referred to in paragraph (5)(a) shall be established by an engineer in accordance with good engineering practice.
94.1(7)An employer shall ensure, before concrete is poured,

(b)
that the engineer, or the competent person designated by the employer, as the case may be, authorizes the pour in writing.
94.1(8)An employer shall ensure that the written authorization referred to in paragraph (7)(b)
(a)
is kept on the project site, and
(b)
is made available to an officer on request.

(a)
the concrete is strong enough to support itself and any loads that may be applied to it, or
(b)
the concrete is adequately reshored.
94.1(10)Where concrete is reshored under paragraph (9)(b), subsections (2), (3), (4), (5) and (6) apply, with the necessary modifications, to the reshoring.
