2.7m Span - Grid Segment for Standard Motor Grids - Notes - Standard Drawing 1565

Oct 24, 2026

Upload by Fishy

Standard Drawing 1565 provides typical general arrangement details for 2.7m span grid segments used for standard motor grids, including required vermin and dog fencing arrangements. The document defines standard grid widths and segmentation ranges based on formation and pavement widths, and specifies design traffic loads and design criteria references. It also lists steelwork fabrication and material standards, welding symbol and consumable requirements, galvanising and welding-slag preparation rules, dimensional units, and associated and referenced documents.

FAQs

What standard motor grid segment size does this drawing cover?

It specifies a 2.7m span grid segment for standard motor grids.

What fencing elements are required for grids with vermin?

With vermin and dog fencing at the top and bottom, and motor grid anchorages with dog fencing only, one at each end of bearers.

What are the key material and fabrication requirements for the steelwork?

Steelwork must meet MRTS78 fabrication requirements, including RHS grade/material standards, bolt and nut classes, hot-dip galvanising standards, and welding and consumable requirements referenced by the listed AS/NZS and ISO standards.
