Total Station Survey in Shillong for Steep Plots

When does Shillong need a total station survey?

Most of the city qualifies, since so much of it is steep, wooded or densely built. Reading direction and range to a quoted 5 mm + 3 ppm, a total station survey in Shillong captures houses, walls, stairways and trees under pines and between roofs. It then places new foundations on the hillside as drawn.

Satellite receivers do well on open ridges, but the commercial heart of the city is crowded. Around Police Bazaar, the old market of Iewduh (Bara Bazar) and busy Laitumkhrah, buildings stand close and lanes are narrow. Many structures step down the hill one floor at a time. Those are total station jobs from start to finish.

Why does slope matter so much to measurement?

Because a plan is drawn in horizontal distances, and on a hillside the distance along the ground is always longer.

Each shot records the inclined range, found by electronic distance measurement, and the vertical angle in one go. The instrument resolves them straight into a plan length and a rise or fall. That is why a total station plan of a Shillong plot often disagrees with an old tape measurement made down the hill: the tape followed the ground. For stake-out, the same reduction runs the other way. A column set 6 m from a wall on the drawing therefore lies 6 m away in plan, not along the slope.

How is stake-out done on stepped foundations?

Level by level, with marks carried down each terrace and checked from a second station. Shillong buildings are often founded at two or three levels as they step down the hill, which makes setting out their construction layouts slower than on flat ground. We set the main grid on the highest firm terrace and transfer lines down to lower levels with the instrument, not with plumb bobs and tapes. Every lower mark is then checked against the grid above. Marks close to a cut edge are offset back to firm ground, because a fresh cutting in wet season can slump overnight.

Why record the houses above and below your plot?

Because on a hillside your excavation can affect a neighbour's foundation, and their drainage often runs across your land. A house downhill may sit only a few metres below the cut you plan; a house uphill may have its retaining wall on your boundary. We measure the visible walls, plinths and outlets of neighbouring buildings along with your own plot. Spot levels go at their foundations, and their condition is photographed on the survey day. The site plan gives your engineer a clear picture before digging starts, and gives everyone a dated record if questions come up later.

How do we work under pine cover?

With a traverse through the trees, tied to control points set in the nearest clearing. Tall pines block satellites but leave gaps between trunks for a line of sight. Stations are placed where two or three trees open a window, legs are kept short, and the loop closes back on its starting control. Those clearing pegs are placed through getting a DGPS survey in Shillong done right. Ground levels and contours from the same field days go into the Mezux topographic survey in Shillong.

Total station survey in Shillong at a glance

Table note: cables and pipes along ridge roads are not visible to a total station; read our utility survey guide for Shillong.

Where footings are planned beside a ridge road, look for buried services before the first pit; GPR survey in Shillong at a glance explains how. Work on the plains below is quicker per acre, and is set out on total station survey in Guwahati.

What are the rates?

A plot up to 1 acre from ₹10,000; ₹3,000 per extra acre; layout or stake-out at ₹8,000 per crew-day. GST is extra, and the written quote shows any travel cost if one applies. A 1.5-acre school compound costs ₹11,500; three crew-days of stake-out on a stepped building come to ₹24,000. On a build lasting many months, one of our surveyors can stay on site with an instrument for ₹1,20,000 per month.

A surveyor of ours lives in Shillong and works from home. The instrument near Police Bazaar or Iewduh is therefore set up at once, or within a working day of approval at most. Steep or wooded plots take longer per acre than flat ones, and the drawing follows about 3 working days after the field work.

How do you book?

Send the location, photos of the plot from top and bottom, the architect's drawing if you have one, and the dates you need. Near the bazaars, name whoever can let us onto adjoining roofs and through back lanes. Then use the quote form for Shillong. Background on the instrument is on our total station survey for Shillong sites page.

Frequently asked questions

Why does your plan differ from my old tape measurement?

A tape follows the slope; a plan shows horizontal distance. On steep plots the difference can be over a metre.

Can you survey a building I cannot enter?

Largely, from outside, using reflectorless readings. Inner walls need access.

Do I need DGPS as well?

For control only, in most cases. Read more on DGPS vs total station for how the jobs are divided between them.

Will you check my plot against land papers?

Papers are compared by the land surveyor in Shillong for your site.

Can work go on in heavy rain?

No. Line-of-sight measurement stops in heavy rain, so monsoon bookings carry spare days.

How do you stake out on a slope that is still being cut?

From marks offset back to firm ground, re-checked after each stage of cutting.
