STREET RENOVATION WITH RIB iTWO CIVIL

Together with apprentice Linus Büchner, Jens Martin was responsible for many tasks in the Schallfeld construction team: These included testing the polygonal points given by the client, compaction and leveling activities, creating a basis for GNSS measurements – both for the foreman on site and for control of the tracked loader and grader – creating various records for construction billing and site plans, and last but not least, providing all the digital data required for surveying, machine control and billing. A unified, thoroughgoing, digital plan for the construction measure was created in-house at Gebrüder Stolz using the RIB infrastructure software iTWO civil. The software has been used at the company since 2016 for civil engineering projects and drainage measures. Martin is the expert in the software system. His tasks also include supporting colleagues in using the software, as he has been working with RIB programs for many years in highway engineering. Martin himself values highly the transparency and optimized interplay of individual functionalities in the new RIB solution iTWO civil, which are an improvement on previous programs.

The engineering office tasked with the planning, Höhnen und Partner from Bamberg, provided a CAD plan as the basis for works. Alignments, gradients and cross-sections were already available in digital form. Likewise the site plan, which was created in dwg format. Further aspects, such as, for example, the digital specification and shaft lists, were at first only available in paper form. “As the basis for the construction in Schallfeld, I created a new digital specification in iTWO civil from the digital data already available and the paper files. This was then compared with the planners’ digital specification. Within the RIB software, we supplemented additional information, such as stake-out data, ourselves,” Martin reports.

Except for a few inconsistencies in the detail of the lane widths in the digital specification and in the drainage plan, the transferal of the plans into RIB iTWO went smoothly. “During the plausibility check before the execution of the building measure, the number of shafts for drainage was found not to be correct,” Martin explains. “After a short consultation with the planners and a small change to the digital plan, in which we replaced two shafts with a slotted channel in iTWO civil, we were able to resolve this small inconsistency very quickly and then use the newly created data in the program.”

From the final state of planning, intended for execution, data were prepared from iTWO civil and made available digitally for the tracked loader and grader.

Billing by cross-section also took place with iTWO civil. The documentation required by the client, consisting of cross-section plans, calculation logs and test files as per REB VB 21.013, were created at the touch of a button and could be handed over in the quality demanded.
