The following operations were performed in order to mark the objective: first a polygonal traverse was made, beginning from S1 and S5 points provided by the designer, out of which 5 terminals-needed to mark the investment- resulted. Second, the insulated foundation pits for the factory shed and the administrative building were marked by RTK-cinemaric method. No absolute accuracy was required for digging. Next, the levelling concrete was poured in the insulated foundations according to grade elevations using level Leica NA 728. Being a concrete pillars structure and having foundations based on barings with anchor bolts, when positioning the horizontal framing, the longitudinal and transversal axes of the objective on wooden pickets with nails were materialized in the field. 2, 3 frame centerings in the foundations were made by using referince line programme out of the total station menu for transversal axis and the extremities of longitudinal axis. The intermediary pickets on the longitudinal axes were marked as alignment points. Vertically, they were graded using the level. The axes were materialized on frames with anchor bolts beforehand, using a metal ruler and a scriber. Their centering was made by keeping the tolerance of +/-7,5 mm/frame. The following items were used for this work: 2 GPS, plus rover base, pacific crest external modem, Leica TCR 407 station, Leica builder 509 station, Trimble POS 180 station, Leica NA 728 level, metal ruler, scriber, tape line. The operations were made by complying with STAS 9824/0-74(Land measurement, land marking of the buildings/facilities, general perceptions), STAS9824/1-87( Land measurement, land marking of civil/industrial/agricultural and zootechnical facilities), guide C83-75( guide for detailed marking in constructions).
