Questions & Answers

Q1: Can you please advise if the asphalt replacement scope extends to the kerb line on Mugga Way? The drawings provided show the scope finishing at the property boundary.

A1: Any new kerb line, where applicable, shall be provided within the Embassy property only.

Q2: Can you please confirm if the "EXISTING GRASS AREA TO BE REMOVED" indicated on the plans is to be replaced with asphalt?

A2: Yes, the existing grass area identified for removal on the drawings shall be replaced with asphalt as part of the project.

Q3: The latest addendum states to allow a total of 12m of electrical conduit; however, the drawings indicate a quantity of 35m. Could you please confirm whether we are to allow as per the addendum or as per the drawing?

A3: Prospective offerors shall allow for approximately 24 linear meters of 50 mm electrical conduit only, comprising approximately 12 meters on each side of the driveway/property crossing, in accordance with the latest addendum.

The electrical system (conduit only) has been prepared as a schematic drawing to illustrate the proposed conduit routing. In accordance with AS/NZS 3000 (Wiring Rules) and standard electrical engineering drafting practices, electrical drawings are diagrammatic in nature and shall not be used for scaled measurements or the determination of exact conduit lengths. The Contractor remains responsible for verifying final routing, dimensions, and site conditions prior to installation.

The quantities identified in the latest addendum shall govern the work and supersede any dimensions that may otherwise be inferred from the schematic drawings. The drawing legends have been updated to further clarify the intended scope. Given the schematic nature of the electrical drawing, prospective offerors shall base their pricing on the quantities stated in the latest addendum and verify final installation requirements during construction.

Please note: The estimated start date for this project is April–May 2027, and work will be aligned with other ongoing works at the residence. Offerors shall confirm awareness of this estimated timeline and adjust their submissions accordingly.
