Belje Winery
The Belje Winery project involved an 8 month process comprising structural design, detail design, workshop documentation and execution which wereall done in a continuous work flow. We were asked to take over an existing design in progress and reduce steel construction costs without exceeding the deadline, to ensure the vintage and large impending harvest of grapes would not be wasted.
At the point we were introduced to the project, the building contractor was already preparing the site, hence precise coordination was essential for the success of the project.
A complete revamp of the original design resulted in an alternative approach to construction that helped the contractor fabricate and erect the construction quickly and with ease. It was thanks to our expertise in cutting edge structural steel software that we were able to coordinate, develop and send detailed designs including 690 (of a total of 2760) corresponding workshop drawings to the steel fabricator within 3 weeks of beginning the project.
The greatest challenge was to maintain worker efficiency on site while resolving structural and architectural issues.

Karanac Farm Complex:
Roof Design
We created a detailed structural design ofa steel roof Truss, including workshop documentation and production supervision for the Karanac Farm Complex. The simple yet efficient roof design was requested by the client in order to improve on the existing timber roofs the client had throughout his site. To date, the complex is still expanding and incorporating the same Truss design across all new developments.

This was one of our most complex steel detailing models. The construction detailing was made for our client in Germany and the construction itself was erected at 3 different sites in Saudi Arabia. The construction was produced multiple times for each location as new elements of existing gas power plants. It consisted of 2 main parts–an exhaust stack and silencer duct. The projects greatest challenge was the need for very precise detailing, ranging from welded pins that hold insulation and inner sheeting,to obstruction lights on an exhaust platform.
The inner sheeting was particularly complex to model due to heavy corner geometry while we also needed to ensure that the fabrication drawings were issued in such manner that after production the inner sheeting coveredthe entire insulation area. Every sheet required its ownunique position within the construction along with different moving and fixed points to allow for the high temperatures inside the construction. The final model consisted of 34 338 individually designed elements.

Substructure of
Solar and PV panel
T +385 (0)1 466 4000 www.nosivestrukture.hr
The project involved ensuring the stability of solar or PV panel substructures. We designed several substructure variations specifically crafted to the varying climate conditions of the different distribution territories. For the most part, the substructure was made of steel elements with a frame containing a cantilevered column, main beam and bracing elements. The solar or PV panels were supported by aluminum beams on a wide range of spans and rasters. Our design work ran concurrently with that of the marketing department so that they could deliver a cost estimate to the clients.
The key consideration and concern throughout the project was that the solar panels were to be distributed worldwide. Hence we dedicated a considerable amount of the timeline to educating ourselves in the international codes and standards for structural design which underpinned the success of the project.
This project involved the development of complex structural design calculations for an agricultural equipment fabricator. The calculations were carried out for various animal feed storage silos which resulted in the optimization of the existing product line.
Storage Silo
Terminal for the reloading of grain and oil seed cargo at the Danube river port of Vukovar. It consisted of a 205m long docking facility that is able to berth river ships and barges with a loading capacity of up to 3 000t and a length of 120m. We were briefed to prepare detailed designs and workshop drawings for multiple constructions at the terminal. We also supervised the fabrication of the steel structures.

Our work involved the structural analysis, framework and reinforcement drawings for the circular center-feed clarifier with a scraper sludge removal system as well as all related auxiliary facilities. The tank has a capacity of approximately 3 217m3. The clarifier consists of the tank which has a diameter of 32m. The tank wall is 4m high with a uniform thickness of 0.4m. The base slab is 0.4m thick, with 6.6% slope towards the center. The sludge drain channel is positioned at the top of the tank wall. The channel consists of a 0.2m thick wall and a base slab that is 0.3m thick.

The scope of this project included structural analysis, framework and reinforcement drawings of the Activated Sludge Tank (AST) and all auxiliary facilities. The AST consists of two tanks of approximately 40 × 65m each and 5.6m height. The tank is composed of RC walls supported on a raft foundation slab with thickening under the main walls. The average base slab thickness is 0.4m with four drainage pits in each chamber. Secondary walls in each chamber are 5.6m high with uniform thickness of 0.3m. External tank walls are 5.6m in height, with variable thickness ranging between 0.35m to 0.7m. Other auxiliary facilities on the tank are two service bridges. Their concrete grade was C25/30 with a concrete cover of 5cm.
The center-feed system is located in center of the structure and is supported by 8 concrete 40 × 40cm columns. Other auxiliary facilities along the reservoir are a drainage chamber, a de-sludging chamber and scum chamber. The thicknesses of the walls and chamber base slabs is 0.3m, apart from the base slab of the de-sludging chamber which is 0.4m. At the top of the de-sludging chamber there are gratings and stair access. The grade of the concrete is C25/30 with a concrete cover of 50mm.

Zürich Stadium

This design for a stadium in Zürich with a capacity for 20 000 people, will become home to two football clubs if it is successful in passing through to development. For this stage of the project we were required to provide a cost estimate focussing on the steel and concrete structures. The stadium roof is made from cantilever trusses with a 24m span on 21.2m raster. The trusses are supported with large vertical oriented trusses called “Mega-Columns” that are 23m in height. The total weight of all the steel structures was 1 100 000kg. In order to get an accurate cost estimate of the precast Raker beams we made a 3D model in Allplan to ascertain the number of different types of beams. We then built a 3D model to find out the total reinforcement weight for each type of beam.
