Sequent Control of Geometry

  • If your architect enjoys to have Your plot with all ist properties in his studio;
  • if the building permission can be received quickly, because all necessary information secured available;
  • if the site manager can overlook everything at a glance;
  • if he has numbers and earth masses under control;
  • if evidence protection and monitoring measures are technically and financially included;
  • if the neighbor has no reason for any complaint and no sway against the plan.
  • In short, if you consist before state, neighbour and bank and possibly with your acquirer easily.

dangerousThe DIN 69901 – 5/2009 defines a project as an intention, which is mostly characterized by the singularity of its conditions as a whole. Temporal, factual, financial, personal and occasional limitations have to be considered. That applies as well for the sequent survey control so far, serving as data deliverer and controller for the site manager.

 

 

From the case by case sequent survey control to the System Control of GEOMETRY.

The conventional sequent survey control we call today “System Control of GEOMETRY”, for it provides the site engineer a steering tool to have the geometry of the site fully under control. Especially he is aware of the actual accuracy budget.

A good framework is half of the planning - no, it is far more, because the success of the planning, the approval and realization as well as the efficiency of a project, depend on it. Unfortunately you are not able to see if the framework is “good” or insufficient.

Whether there are maps, files, measurements, statements or analyses, all the following use of them stand on shaky feet if there are gaps, errors, discrepancies, discontinuities or even worse, if there happen willful deflections or if over the time of their use they are no longer identifiable. Therefore you should develop a framework, which meets the following requirements and criteria:

Full information Consistancy Stochastics
Quality by system Traceability Simultaneousness
Transparency Information transfer Acceptance control

Base for the building permission

GEOHAUS created the exemplary site-plan for North-Rhine-Westphalia in 1976, 1985 an 1990 and the new German states in the nineties. It became a benchmark – half a million times dispersed. This product was continuously refined with the goal to present a completely reliable planning basis to the architect, an exact control basis to the building owner and a secure basis to the building authority issuing the official building permission.

The ongoing site work jeopardizes any control point at the ground, so that one should not concede them to all craft disciplines. Measuring point pillars bring quality over the whole construction period for all craft disciplines.

The metadata make the quality of the design transparent and the performance becomes measurable. They brief about the measuring and caculation accuracy and the reading accuracy as well as the resulting accuracy on a certain structure (roof eve, roof ridge, floor etc). The statistics instructs about the number of moved factual data and design elements as well as the time of marking. The “Koordinatenart” (sort of coordinates) indicates the mathematical mapping model.

The transfer of the planned geometry into the construction site depends mainly from the point-identification, which means from the accuracy, which can be gained by defining an object point on a given structure.

The cross-linking of devices, machines, sensors and men is already beginning. The result is a seamless communication between the sensor to the internet, workforce and fleet management and of course theft protection as well as personal protection. The application software of the “System GEO-box” makes it possible ( Sensor & Telemetry)

For big building projects it is necessary that the general public gets positively aware of the vision to be put in reality. For this the three-dimensional, photo-realistic visualization of the architectural planning is the right tool. In GEOHAUS we have interdisciplinary knowhow for such work: Visualization, shadow calculation od 3D-city models from LoD1 to LoD3.

Preserevation of evidence and monitoring are based on the time related surveys of any situation. This survey can be performed by polar (tachymetrical), orthogonal measurements, the data can be collected by laser scan or laser slam, the information can be presented by survey photograph, panorama photo or Ortho-photo. The conclusiveness may not be reduced by further processing.
