12d Innovation Survey and Construction Gold Award

 

The 12d International Innovation Awards have been held in 2012 and 2014, sparked by the Christchurch rebuilding project, and are run by civil and surveying software company 12d Solutions.

The awards are designed to acknowledge clever and inventive solutions and projects by 12d users around the world.

Eliot Sinclair were very successful at the 12D Innovation Awards in 2012 and 2014, thanks to the talent of our staff.

In 2012, Sam Cech brought home the Gold Award for his entry for Sewer Collector Mains Design, and in 2014 Licensed Cadastral Surveyor Andrew Sinclair took out the Overall Gold Award for his entry on Hydrographic Cross-Section Tools.  Eliot Sinclair have been involved with hydrographic cross section surveys across the South Island with our single-beam echo sounders. Survey data is used to analyse siltation and flows in rivers and lakes, so it is imperative this data is free of errors, which is where Andrew’s innovation came to realisation. At Eliot Sinclair, we are able to create two innovative macros allowing hydrographic cross-section data to be cleaned and edited in 12d Model, using the section view.

Eliot Sinclair were also successful in bringing home a Gold Award in the Survey and Construction Sector, with Survey Graduate Graeme Crouchley and Andrew Sinclair submission on Building Damage Assessment. The basis of their submission centered around the way in which, as part of the Canterbury Earthquake repair and rebuild, assessments of damaged buildings are undertaken at varying levels of detail. Engineers need to make critical decisions based on the information provided by survey. Generally the critical information is around comparing floors to a horizontal plane and walls to a vertical plane. The analysis of this data needs to be systematic, repeatable, and free of errors. However, different methods for calculating slopes give different results.

  •  Wall verticality – Eliot Sinclair have created a macro to display vector symbols and magnitudes perpendicular to a wall. Two coordinate datasets are compared, generally bottom of wall vs top of wall, a wall alignment bearing is input and vectors are automatically generated for the component of lean in or out from vertical. Magnitudes of lean are expressed in mm over height difference, and as a percentage grade.
  • Floor slopes – We have developed a standard for presenting floor slope data by colour shading areas that exceed a given grade (e.g. lin 200). The 12d in-built ‘Slope Analysis Colour’ tool enables triangles in a tin to be shaded based on their slope/grade.

We have identified 3 different data source methods for creating this shading, which consist of, shading the raw tin triangles between surveyed points, gridding the survey data and shading the resulting ‘regular’ tin triangles and creating contours from the survey data and shading the tin triangles from a combination of surveyed points and 3D contour lines.

For each project we can assess which method is most appropriate to give a true representation of the floor surface. The result is a detailed and survey accurate data presentation that is user friendly for insurance assessments. With data presented clearly, engineers and assessors can make well informed decisions about the fate or repair strategy for damaged buildings.

When the surveyor is called in, it is important to present accurate floor level and wall verticality information in an easy to interpret format with impact.

Ultimately, the processes at Eliot Sinclair continue to develop, offering our client reductions in time and cost as well as great confidence in the integrity of the data the receive.
