“Computational Civil Engineering 2005”, International SymposiumIaşi, România, May 27, 2005Notes on microtriangulation network types as applied to thestudy of construction displacementsCarmen NutiuPh. D. Eng., Senior Lecturer, Faculty of Civil Engineering, Technical University of Cluj-Napoca,400363, RomaniaSummaryThe wide diversity of construction types and methods of designing and buildingvarious structures made it necessary that the civil engineer expert should beinvolved in topographical measurements and observation in time of the edifices;these observations are made over long periods of time, including the buildingprocess itself and the commissioning.The study herein aims to present several types of microtriangulation networks usedin topographical measurements, along with observation points and supportingpoints, which make part of topographical methods applied to the study ofconstruction displacements.In fact, every objective to be analysed poses different problems pertaining tolocation, type of terrain, size, purpose and utility; this leads to choosing a type ofnetwork that has to meet all the requirements in terms of accuracy and to offer thepossibility of performing the measurements and satisfy all demands imposed bysuch experiments.KEYWORDS: topographical-geodetical methods, microtriangulation network,displacements and deformations in construction, control points, observation points,orienting points.1. INTRODUCTIONIn choosing best options for designing and commissioning the constructionbuildings we must consider a thorough and complex study which is to be made atthe beginning of the construction process, during inspection, execution andcommissioning.During designing phase, the experimental study consisting of construction testinghas the following objectives:• Numerical values for all parameters that describe the construction from thephysico-mechanical point of view;
