PROCEDURAL GUIDELINES
3.1 INTRODUCTION
The
following procedures are recommended in respect to the Engineer's
responsibilities in preparing, inspecting, and certifying a PWF
design.
3.2 FAMILIARIZATION
a)
Review current Codes
b)
Determine site grades and subsoil conditions.
c)
Review architectural plan to identify:
(i)
unbalanced backfills
(ii) window openings
(iii) stairwell location(s)
(iv) garage pad elevation
(v) drops or raised areas in subfloors
(vi) brick veneer locations
(vii) basement wall heights
(viii) other relevant components
3.3 DRAWINGS AND SPECIFICATIONS
a)
The Engineer should ensure that the drawings, specifications, and
framing details prepared for a PWF are explicit enough to be understood
by the builder.
b)
A site and building specific drawing must be prepared for each foundation.
It should show the following information:
(i)
location of foundation with respect to property boundaries or
be referenced to another drawing which provides that information.
(ii)
outside dimensions of the foundation wall.
(iii)
typical vertical section(s) through the foundation wall showing
floor elevations and the elevation at bottom of footing, or equivalent
detail.
(iv)
portions of the foundation for which each detail design applies.
(v)
maximum backfill heights
c)
Special framing details required around stairwells, window openings
and dropped or raised floors should be detailed on the drawings.
d)
Drainage material, nail-fastening connection specifications, dampproofing
requirement, lumber specifications and backfill material specifications
shall all be shown on the drawings or in the specifications.
e)
The Engineer responsible for design should review the drawings and
specifications with the Client prior to start of construction.
f)
The site specific drawing must bear the seal of the Design Engineer,
signature and date it was sealed, and where applicable, the permit
stamp of the firm preparing the design.
3.4 INSPECTION
(a)
An Engineer, or a suitably qualified person working under the direction
of an Engineer, must examine the completed construction of the PWF
project to confirm that it has been constructed in accordance with
the intent of the drawings and specifications. The inspection may
be performed by, or under the supervision of, an Engineer who is
not the design engineer.
(b)
If the inspecting Engineer is not also the Design Engineer, he/she
should examine the drawings and specific details of the PWF prior
to visiting the site. Any uncertainty concerning the design or details
must be resolved through discussion with the Design Engineer.
(c)
The inspecting Engineer must not accept or approve any changes in
the design of the PWF without notifying the Design Engineer.
