Levelling staff in 3 m, 4 m, and 5 m folding aluminium versions — essential for differential levelling surveys with auto levels and dumpy levels on road, building, and drainage projects across Northeast India. In stock at Multi Trade Combines, AT Road, Guwahati.
A levelling staff (surveying level rod) is the field partner of every auto level, dumpy level, and digital level instrument — without it, the level instrument cannot give a height reading. The levelling staff is a graduated aluminium or fibreglass rod held vertically at the point to be surveyed, and the instrument operator reads the graduation (E-pattern or face pattern, in metres and centimetres) visible through the telescope crosshair. The height difference between two staff readings at a fixed instrument position gives the elevation difference between the two ground points — the fundamental measurement in differential levelling, which underpins all topographic survey, road design, drainage planning, and building layout work.
In Northeast India's active civil infrastructure sector — NHIDCL highway projects across Arunachal Pradesh and Nagaland, PMGSY rural road construction across all eight states, Brahmaputra embankment and flood control works, and the dense urban development underway in Guwahati's expansion areas — levelling surveys are conducted at every stage of a project: from initial topographic survey and alignment design, through foundation setting-out and drainage gradient marking, to final as-built level surveys for handover documentation. A well-made folding aluminium levelling staff with clearly printed E-face (or face) graduations is an essential, high-use field instrument for every survey party.
Multi Trade Combines stocks folding levelling staffs in 3 m, 4 m, and 5 m lengths at AT Road, Guwahati alongside the full range of surveying instruments — auto levels, digital theodolites, total stations, prism sets, ranging rods, and plane tables. The folding format is preferred in field conditions across the Northeast because the staff can be carried safely on motorbikes or in small vehicles on the hill roads that are standard access routes to many survey points in Assam, Meghalaya, and Arunachal Pradesh.

A levelling staff (also called a level rod or surveyor's rod) is a graduated vertical rod held upright at the point being surveyed while the surveyor reads the staff graduation through an auto level or dumpy level telescope. The graduation reading at the instrument's line of sight gives the reduced level (height) of the ground point relative to a benchmark. Levelling is essential for road and railway alignment design, building foundation layout, drainage design, and topographic mapping — all commonplace in Northeast India's infrastructure boom.
A 3-metre folding staff is the most common for urban setting-out and building work where bench mark differences are small. A 4-metre staff gives more range for rural land levelling and road alignment work. A 5-metre telescopic or folding staff is used on bridge foundation surveys, river cross-section levelling, and hilly terrain surveys where the instrument setup is at a significantly different height from the staff position. Multi Trade Combines stocks all three lengths at AT Road, Guwahati.
