Lifting and handling equipment

With the experience gained in the design of large works, we are also attentive to the conception of the assembly and construction site phases. We aim to provide solutions that are truly compatible with the conditions of the site. To pursue this goal, we establish fruitful collaborations with producers of overhead cranes, winches, and gantry cranes to devise together the best technical-economic solution that meets the expectations of the Clients. Thanks to the collaboration with technicians in the sector, we also provide risk analysis services, assembly diagrams also for the electrical / mechanical / hydraulic parts and use and maintenance manual.

Launch projects

The launching operation of a deck consists in setting up the infrastructure by lifting from below, front launching by pushing, launching with cantilevered advancing segments or various special ones. The launching method influences various structural aspects, such as the type of section and the construction details and is also done by analysing the conditions of the environmental context, such as the possibility of having a launching field for the launch of the segments, or the positioning of the self-cranes inside the riverbed. These aspects are analysed during the preliminary coordination meetings with the clients following which the best possible solution compatible with the characteristics of the building is proposed. A preparatory BIM model is created for the study of the launching and construction phases of the works. The necessary equipment is designed, such as gates and temporary towers for altimetric alignment, and temporary lifting and pushing structures. The consultancy service includes the study of the structure during the transitional period, how the bending stress changes when the segment passes through a section of span and pile, or the concentrated action of sliding on sleds or trolley racks, and the need to integrate the structure with any temporary stiffeners.

Fatigue design of cranes and overhead traveling cranes

We have worked for several years in a steel plant providing consultancy on the structural design of lifting equipment and runways for bridge cranes. We design the structures according to the UNI EN 1193-6: 2008-09 standard, analysing all aspects of actions on the flange and weld seams and considering the fatigue analysis according to the imposed work cycles. In the case of existing beams, we verify the need to add stiffeners or beams for torsional stability in the case of commissioning of overhead cranes with greater capacities, considering the buckling checks of the core panels. Information about buffers and fixing clips are studied together with the Client based on the products available on the market. We are familiar with the Machinery Directive 2006/42 / EC and the harmonized standards UNI EN 13001 which cover both general aspects concerning the structural calculation of lifting appliances and specific aspects of the various constituent elements, such as, for example, the calculation of ropes, cylinders hydraulic systems, wheel-rail contact, etc.
Consult us for specific advice also for the evaluation of the functioning of existing equipment.

Support structures for storage silos, conveyor belts, pipe racks lines

Drafting of complete lay outs for production lines together with the study, design, and adaptation of customized machines in existing systems, revision, adaptation, and capacity increase of existing machines (e.g., modular filters, etc.), research, consultancy on existing plants to improve their efficiency (e.g., energy saving, reduction of maintenance costs, reduction of plant shutdowns, etc.), problem solving. Projects developed in 3D BIM models complete with bearing structures, belts, winches, conveyors, for the control of interference and vision of the production process.

Stadiums and Arenas

Thanks to the collaboration with general firms and internationally renowned architects, we have gained experience in the executive development of large structures where it is important to integrate structural, static, and dynamic calculation, together with the multidisciplinary design of HVAC systems, mobile scenography structures, support for lighting and installation audio.

Bridges and Infrastructures

From the shelter of the railway terminal to the design of metal decks with large spans for motorway traffic, we are involved in the structural design of bridges and viaducts: from the study of the anti-seismic supports to the optimization of the weights in the executive phase. Thanks to a group of experts in the assembly of these works, we provide advice to companies to find the best technical-economic solution in the launch of infrastructures, personally designing temporary towers, launching systems, forearms and handling slides, proposing the optimal configuration positioning of the available Auto-Cranes.

Commercial and Office Building

Executive design of large logistics and management buildings including static and dynamic structural analysis of the load-bearing elements in steel or reinforced concrete, stair towers and pipe racks, calculation report signed by a qualified technician. We develop the load-bearing structures and the building envelope according to a BIM process with definition of the panels, tinsmiths, and water disposal system from the roof. In this way we guarantee to the client the exact calculation of the quantities and waste of material, which on large dimensions allows for control and savings of material purchased. Structural analysis to find local intervention solutions for cutting panels and positioning AHU machinery, fans, lighting bodies and lifeline systems, even on existing tiles, with solutions to be engineered according to the needs of the assembly teams.

Industrial installations

Executive design of industrial plants for new lines or expansion of existing lines, multi-storey buildings, and pipe racks in the steel sector for integral or electric steel mills, energy production plants for thermoelectric plants, cogeneration and trigeneration, petrochemical plants, OIL 'Gas, and waste treatment. Based on the project specifications and the documentation provided by the central technical office, we define the layout of the new machinery in addition or replacement to the existing ones, evaluating which parts to maintain or modify to allow the achievement of the expected performances. We develop the project according to BIM process. Therefore, the parts of the existing plant can be detected by laser-scanner with point cloud return. This will make it easier to check for interference with moving machinery and equipment. We can develop the design of piping lines according to the flow diagram (P`ID) of the instrumental part with the assignment of specific equipment tags, identification of components by means of identification code and nominal diameters and isometric drawings. In addition to the design of the load-bearing structures, we define the access routes, stairs, landing, and maintenance walkways with the definition of the geometries required by the regulations on hygiene and safety materials for work at height.

Power lines and telecommunications

We are active in the energy transport sector by developing the detailed construction design of the pole and related civil works starting from the preliminary design of the high-voltage line. We perform BIM Modelling - LOD F / G through Tekla Structures according to the UNI 11337-4: 2017 standard both parts.

BIM 3D 4D 5D

The natural consequence of the experience gained in the development of BIM processes was the achievement of the BIM Manager certification according to the UNI EN 11337 standard by Mr. Corsi, partner of LMSteel Consulging sagl. The license was issued by ICMQ in 2018. This formal step was nothing more than the formalization of concepts and knowledge gained in recent years on international projects, especially on the French market where the Building Information Modelling methodology is implemented by large General Contractors such as Vinci Construction France and with whom we had the responsibility of collaborating. Our skills allow us to manage information in digitized construction processes, to draw up the BEP (BIM Execution Plan) also known as PGI (information management plan) with the aim of defining the information flows in the digitized construction project. The consultancy services offered include an initial mapping or integration of existing processes, a definition of the necessary tools in terms of hardware and software, a definition of the necessary BIM Specialist and BIM Coordinator figures, and project coordination (BIM Management) among the stakeholders of the disciplines involved, with supervision of the order and control and resolution of interference in the federated model. We can assist Clients and General Contractors up to the final phase of Facility Management and as-built drafting. The process can be managed both for software on Autodesk platform (Advance Steel / Navis Works / BIM 360) or Trimble matrix (Tekla Structures / Trimble Connect).

Preliminary and feasibility studies

The consultancy service begins in the concept phase by evaluating the characteristics, costs, and possible results of the project based on a preliminary rough idea. An elaborate will be presented with conceptual sketches and elevations or alternatively an Architectural 3D model with renders designed to present the project idea. A report will demonstrate the technical, economic, legal, and operational feasibility. In particular, the costs / benefits of the project, any conflicts with legal requirements, and the time planning of the intervention based on the financial plan will be presented. Contact us for a free, no-obligation quote.

Rendering and animations with simulation of laying sequences

We assist clients and general contractors in digitizing an idea. We have learned the importance of not leaving any phase of the design unexplored, whether it is the maintenance of a pulvinus, the removal of a temporary pile, or the lifting of a slab of the deck. For this reason, it is important to define in the digital model the time sequence of construction and installation, highlighting all the auxiliary operating tools that will intervene in the history of the project. To make our communication effective, starting from the 3D BIM model, we animate the structure by combining precision and graphic quality and returning to the Clients a video in .avi / .mp4 format valid for evaluating the goodness of the design choices, even in the tender phase of the procurement.

Supervision and assistance in construction and assembly

The construction and assembly assistance and supervision services ensure that your project is configured correctly without construction and installation errors. Thanks to the many years of experience of our technicians involved in the supply and commissioning of large structures, we can provide technical personnel on site and expediting to perform the rigorous dimensional checks and technical project specifications. We provide out-sourcing technical personnel in case a constant evaluation of the BIM model is required at your offices. We give our best contribution so that the work is completed safely and on time.

The services include the development of the lines according to the geometry of the plant with particular attention to interference between MEP systems and load-bearing structures, the definition of the types of support (cradles, shoes, u-bolts, etc.) according to the requirements of the Client, positioning of the equipment nozzles, isometric drawings, purchase technical specifications, Material Take Off (MTO), workshop and assembly plans. The development of 3D models in BIM process is carried out with ESAPRO 3D, ESA-IN, Tekla Structures and Navisworks software.

BIM for Manufacturers and construction management

Following many years of experience in close collaboration with manufacturers in the steel sector in the development of workshop and assembly plans, we have become a reference point for construction design with the "" BIM oriented "" approach. Our detailed engineering services (BIM Design for Manufacturing) follow the practice of good building, the technical requirements of the UNI EN 1090-2: 2018 standard for the execution of steel and aluminium structures. In particular, the specifications for the execution classes EXC3 EXC4 are known, the dimensional tolerances of the lamination of the profiles, the slots and chamfers required for the weld seams, the shrinkages during the automatic welding process on welded composite PRS beams, the holes, and preparatory vents for immersion in the galvanizing tank and the recommendations of the IIS (Italian Institute of Welding).
Our 3D models made with 14 licenses of Tekla Structures (Trimble) are developed up to a level of detail F (LOD 500) including all information attributes on the specifications of the materials (LOD and LOI), bolts, welds, plates link. The construction drawings are extracted from these models which together with the NC (Numerical Control) files and the DSTV (Deutsche Stahlbau-Verband) files allow collaboration and dialogue with the production department. All models can be exported in .ifc format for interference checking on Autodesk (Navis Works, BIM 360) or Trimble (Trimble Connect) platforms, or viewable by free software such as BIM Vision. We provide assistance to the Technical Department of the Metal Builder to find the best dialogue solution between the BIM model and the NC machine, converting into .step format in the case of pipes or developing the grooves and welding preparations if the machine is equipped with the possibility of automatic execution of cuts in any angle (e.g. Microstep Profile Cut - CNC pipe, profile & Sheet cutting machine). In the case of wooden structures, we develop the model of the beams or X-Lam panels, subsequently providing the interoperability files to Dietrich's software, a leader in the 3D CAD / CAM sector for wooden constructions.
For works in reinforced concrete and civil engineering, in addition to the volumes of concrete, we completely develop the longitudinal, diffused reinforcement and stirrups system, then drawing up the purchase lists for the bars for the Service Centres.

Project management

We have the skills for multidisciplinary project coordination (architecture, civil, structures, MEP, cladding) which include planning, technical meetings with clients, supervision of works, cost control and progress, assistance in site. The correctness of our operating method is certified by the UNI EN ISO 9001: 2015 quality management system.
