3D laser scanning James Thomas (pmsurveys uk, Survey Manager)
3D laser scanning is the most versatile, accurate and fastest method to collect data in the field today. Capable of scanning vast areas remotely and accurately at distances of up to 300m, it provides a highly adaptable and affordable solution to all surveying and modeling situations and allows us to provide more detailed products than using conventional methods.
The remote nature of this approach has many clear benefits. It is an ideal solution if access can be a safety problem or awkward, often negating the need for raised platforms or additional safety rails. It also represents a perfect approach in fields where site shutdown or disruption can be a difficult and costly procedure. Roads and rail networks are increasingly busy and this fast, remote approach minimizes any interruption to normal operations.
If you have never seen the benefit of using full 3D models and scanning in your operations, then now is the time to get on board. Phone, email or write to us and we will discuss the benefits of what we do, and how we can help your organization.

Site Clearing
The whole area to be occupied by the completed works including ancillary earthworks for drains and diversion levees is to be cleared and grubbed plus a clearance of 2m from tops of cuttings and toes of embankments.
Clearing includes removal and disposal of all trees, stumps, logs, timber, scrub, vegetation, minor structures, refuses and other material unsuitable for incorporation in the work.
Grubbing is to be carried out to the level of 0.5m below natural surface.
Holes left after grubbing under proposed embankments are to be filled with sound material and compacted in layers as for embankments.
Regarding fauna and flora of the site, approval shall be taken from the environmental division prior to clearing and grubbing.

3) One and a half meter is enough to carry out grubbing, isn’t it?
4) What can be done with holes left after grubbing?
5) Is it necessary to take approval from the environmental division?
