- Unless otherwise specifically documented, the professional engineer's
professional liability is limited to the scope of work as indicated on the
sealed drawings, specifications and reports which would pertain to work
typically required to be engineered and professionally sealed by the local
authority having jurisdiction. Portions of work indicated but not typically
requiring engineering and professional seal by the local authority having
jurisdiction is considered outside the professional engineers scope of work and
is the responsibility of others.
- Where the local authority having jurisdiction (AHJ) charges permit fees
for a review and inspection process, and the AHJ mandates the responsible
professional engineer (P.Eng.) to provide a professionally sealed building
design summary form (BDS or AHJ checklist), the P.Eng. does not take
responsibility for the correct answering of mandated questions which are
ambiguous or not involving the work being completed by the building trades
working under that particular P.Eng's supervision. In all cases, the P.Eng.
retains the sole right to interpret the AHJ questions as well as the answers
provided. If further clarification is required, the AHJ is encouraged to
retain competent degreed professionals conversant and specifically
knowledgeable in the discipline being reviewed in accordance with NFPA
standards to interact as necessary with the design P.Eng.
- In cases of ambiguous design issues, and no proper clarification is
obtainable from the AHJ, then it is assumed the P.Eng. will utilize
historically approved design methods which will be liberally accepted by the
AHJ with the benefit in the case of judgement going to the permit payer.
- For interpretations of items, specific notes, and/or general notes, the
interpretation of the professional engineer shall be accepted and implemented
for use. For record purposes, review all items, specific notes and/or general
notes and notify the professional engineer of any concerns or discrepancies.
- Where the authority having jurisdiction provides permit numbers and requires
their inclusion in documentation the responsible professional engineer does not
accept liability for permit number accuracy as those numbers are outside of the

- Permit implications - Upon receipt of permits, the electrical and mechanical
contractors shall submit copy of the mechanical and electrical permits and
associated drawing mark-ups to the responsible professional engineers. The
respective contractor is responsible for completing all items noted by the
authority having jurisdiction - without additional cost.
- Where equipment provided in contract or by others requires building system
connections or interconnections, provide a complete compliant connection in
accordance with the approved plans and specifications as well as all manufacturer's
recommendations and instructions. Adhere to all manufacturer's cautionary
- Provide owners with all manufacturers information accompanying mechanical
- Confirm all structural related construction issues such as mechanical
ventilation openings, holes in structural members or equipment bases with
the project structural engineer prior to proceeding.
- Provide owners with all manufacturers information accompanying electrical
- Confirm all structural related construction issues such as drilling holes
in structural members, installing street lighting bases and equipment bases
with the project structural engineer prior to proceeding.
- Carefully examine all drawings and specifications relating to the work to
be certain that the work under this contract can be satisfactorily carried out
and prior to submission of tender, examine the work of the other trades and
report at once to the Engineer, any defect, discrepancy, omission or
interference affecting the work of section or the warranty of same.
- The drawings accompanying these specifications are intended to show the
general arrangement and extent of the work to be done, but the exact location
and arrangement of all parts shall be determined as the work progresses. The
location of the outlets, equipment, etc. as given on the drawings are
approximately correct but it shall be understood that they are subject to
such modifications as may be found necessary or desirable at the time of
installation to meet any structural, mechanical or architectural conditions.
Such changes shall be made by the Electrical Contractor, as directed by the
Engineer without additional charge.
- For all Ontario projects: the successful Electrical Contractor shall submit to the
Electric Safety Authority all drawings and specifications required to be
submitted by the Electrical Engineer for plans examination purposes. The
successful Electrical Contractor shall pay all plans examination fees. The
Electrical Engineer shall provide the drawings and specifications required
for submission. The Electrical Engineer subrogates all responsibility for

- All electrical distribution equipment including panelboards, central
distribution panelboards, meter centers, transformers, splitters, disconnect
switches, motor control centers, transfer switches, enclosed circuit breakers,
customer service termination enclosures shall have terminations suitable for
copper or aluminum conductors based on 90 degree Celsius conductors. Equipment
bearing labeling indicating terminals are suitable for 60 or 75 degree Celsius
only, will be rejected as determined by the responsible professional
- Always consult the electrical inspection authority in your
province/territory for more specific interpretations.
- When installing cable assemblies, maintain adequate spacing between cables
and avoid cable bundles. Special attention must be taken to maintain cable
separations through fire stopped fire wall penetrations and in areas where
cables are installed within thermal insulation.. Do not tie-wrap excess cable
assemblies. Follow all cable assembly manufacturers installation recommendations
as well as requirements of the local authority having jurisdiction.
- At each roof top unit, place a separate circuit weather-proof convenience
- Where the mechanical equipment manufacturer's installation information
requires copper conductor connections to the equipment, the electrical
contractor must complete final connection in accordance with the manufacturer's
requirements without additional cost.
- Individual electrical disconnect switches within site are to be provided for
all mechanical equipment including duct mounted electric heating coils.
