    Administrative
  1. 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.
  2. 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.
  3. 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.
  4. 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.
  5. 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 engineers control.

The respective contractor is responsible for completing all items noted by the authority having jurisdiction - without additional cost.
  4. 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 warnings.
    Mechanical
  1. Provide owners with all manufacturers information accompanying mechanical equipment.
  2. 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.
    Electrical
  1. Provide owners with all manufacturers information accompanying electrical equipment.
  2. 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.
  3. Drawings
    1. 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.
    2. 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.
  4. 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 the project electrical plans examination requirements to the successful Electrical Contractor.
  5. 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 engineer.
  6. Always consult the electrical inspection authority in your province/territory for more specific interpretations.
  7. 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.
  8. At each roof top unit, place a separate circuit weather-proof convenience receptacle.
  9. 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.
  10. Individual electrical disconnect switches within site are to be provided for all mechanical equipment including duct mounted electric heating coils.
