Smart Engineering starts manufacturing new SmartFibreC equipment

Smart Engineering starts manufacturing new SmartFibreC equipment

News

Smart Engineering has started the manufacture of three new SmartFibreC equipment for commercialization in the international market. The Spanish-made SmartFibreC equipment is the only non-destructive evaluation system (NDT) on the market that allows the determination of the content and orientation of metal fibers in fiber-reinforced concrete (FRC) specimens. As it is NDT equipment, the analyzed specimens can be used in other tests, such as the Barcelona test, which characterizes the residual flexural strength of FRC. The combination of both tests enables a simple and robust FRC quality control system with fewer uncertainties than those currently used.

The equipment being manufactured will be used in different international projects of high relevance. One of the equipment has been acquired by the Bekaert company, a world leader in the manufacture and commercialization of structural metallic fiber for use in concrete, which will implement it in the Asian market. Likewise, another of the equipment will be introduced, together with the Barcelona test, as a control method for one of the sections of the HS2 “High Speed ​​Two” project, the largest infrastructure construction project in Europe, which aims to improve the railway network high-speed train from the United Kingdom linking London with the north of the country.

The use of the SmartFibreC equipment allows the determination of the content and orientation of metallic fibers in concrete specimens, both cubic and cylindrical, with an accuracy of up to 3%. Thus, its use increases reliability and reduces the uncertainty associated with traditional FRC characterization tests. In combination with the Barcelona test, it provides a competitive advantage in the field of quality control and characterization of FRC and increases the overall sustainability of the projects thanks to the fiber content optimization that can be achieved from the statistical analysis of the data obtained from both tests.

The SmartFibreC is a compact and robust device, suitable for use both on site and in the laboratory. It is made up of a measuring cell, an electronic inductance measurement and data recording system and the coaxial connection cables. The internal battery of the electronic system allows an autonomy of more than eight hours and the USB connections allow sending of data to other devices for analysis and treatment. Its operation is based on the alteration of the magnetic field generated inside a measuring cell when introducing a concrete specimen with metallic fibers, which results in a variation in inductance. This variation allows the measurement of impedance, which is directly proportional to the content of metallic fibers, and is also influenced by its orientation with respect to the field.

The SmartFibreC equipment is already used, together with the Barcelona trial, as a FRC quality control system in different international projects, such as the Follo Line in Norway or the Bank Station Capacity Upgrade Project in London. The commercialization of the SmartFibreC equipment is one more example of the firm will of Smart Engineering to strengthen its support activity for large companies in the construction sector, providing them with new technological developments in the field of Civil Engineering and new materials and acting as a link between knowledge and business.

Smart Engineering will develop a model guide for the evaluation of public tenders

Smart Engineering will develop a model guide for the evaluation of public tenders

News

Smart Engineering together with the company Constraula carried out since last February 2o2o a project to develop the conceptualization of a project evaluation model in public tenders carried out by the different Public Administrations. This project aims to serve as a guide for the technicians of the AAPP, so that it allows them greater ease and transparency in the classification, evaluation and prioritization of the different offers. The project focuses above all on maintenance contracts for public roads and buildings, as well as development projects and new buildings.

The current Law 9/2017 of September 8 of Public Sector Contracts on the procedures for the award of public contracts for works, services and supplies was aimed at achieving greater transparency in public procurement and achieving better value for money. . For this, the law indicates that the design of the award criteria must ensure that the highest quality works, supplies and services are obtained by including qualitative, environmental, social and innovative aspects related to the object of the contract.

However, the reality of the sector indicates that, today, public tenders have failed to introduce, in a transparent, objective and traceable manner, the aforementioned issues. Based on these issues, the project proposes a new evaluation model that incorporates aspects related to transparency, freedom of access, non-discrimination, as well as the consideration of social and environmental criteria and attributes.

The methodology of this study is based on the MIVES multi-criteria methodology, developed by the UPC. This methodology allows taking into account economic, environmental and social factors, as well as the different circumstances and specific parameters of each work or contract, promoting the different offers and alternatives, their best approaches, those of their employees and teams, and their conditions of social implantation and environmental of the project and / or the work in the territory.

The model incorporates a decision tree that will include as indicators the context of the work, the experience of the company, the characteristics and technical conditions, the plan of works and innovation, as well as the impact on the social and environmental environment.

Smart Engineering continues with this project its line of business oriented to the development of tools to help decision-making, sustainability assessment and investment prioritization, all based on the MIVES methodology. Examples of this business line are the Avalua project developed for the Barcelona City Council, the sustainable prioritization model of the AGBAR distribution network or the investment prioritization model for the Zonal Plan of the Barcelona Provincial Council.

Smart Engineering works on the development of tools based on autonomous learning

Smart Engineering works on the development of tools based on autonomous learning

News Uncategorized

Smart Engineering has started a new project at the beginning of the year for the development of tools based on autonomous learning and massive data analysis, with application in different areas of civil engineering ranging from the precast sector to construction. This project is part of a Torres Quevedo grant for the incorporation of doctors to private companies, from the Ministry of Science and Innovation (PTQ-18-90877). Thanks to the aforementioned help, Tai Ikumi PhD has joined Smart Engineering.

Nowadays, data is positioned as one of the most dynamic sources of economic benefit in many economic sectors. Data analysis has shown that it has the ability to improve the performance and productivity of any economic activity. However, its use in the civil engineering sector still remains marginal. In fact, it is often openly recognized that in many cases the registered data is not even analyzed. This is due to the difficulty of allocating highly qualified human technical resources to tasks that are still carried out very manually today in the field of civil engineering. These types of practices run counter to current trends, as they disregard the enormous potential of the data.

The general objective of the project is the development of data-based products for the optimization of construction processes. To meet this technological and scientific challenge, models based on machine learning are currently being developed capable of predicting the evolution of the mechanical properties of different concretes (conventional, ultra-high resistance, sprayed, fibre-reinforced) based on dosage and curing conditions. This line of activity encompasses the existing project with Chatu Tech for the development and commercialization of chips with RFID technology for use in concrete structures and elements.

The integrated sensor solution together with the intelligent algorithm allows real-time wireless monitoring of the resistance evolution in concrete elements. This is a critical piece of information that enables the optimization of a multitude of construction processes, such as the formwork stripping time, the opening pavement to traffic, the tensioning time of the prestressed cable, etc. Any reduction in construction / manufacturing times translates directly into a minimization of the environmental impact of the activities and the associated costs. Currently, the first tests on an industrial scale are already being carried out, both in the field of civil works, underground works and precast, resulting in very promising results.

Smart Engineering collaborates on the Iberpotash Cabanasses mine ramp project in Súria

Smart Engineering collaborates on the Iberpotash Cabanasses mine ramp project in Súria

News

Smart Engineering collaborates with ICL Iberia – Iberpotash on the “Cabanasses Mine ramp” project, in Súria. This project is the longest mining tunnel in Spain. It is a ramp with a length of five kilometers and that will reach 900 meters deep. The “Cabanasses Mine ramp”project will allow the direct transport of salt and potash from inside the mine to the treatment plant, without having to transport the mineral through the urban center of Súria as it is being done today.

The works of the “Cabanasses Mine ramp” project are carried out using the New Austrian Tunnel Construction Method (NATM) and using shotcrete to support the tunnel. The “Cabanasses Mine ramp” project represents a technical challenge, given the operating conditions and the characteristics of the tunnel (length, depth, slope). This together with the salinity conditions and the mechanical requirements for the depth reached, puts the level of demand on the materials used at a very high peak.

Smart Engineering has been collaborating in the “Cabanasses Mine ramp” project since 2018, providing technical advisory services to the company ICL Iberia – Iberpotash. Smart Engineering advises on aspects related to the design of projected concrete mixes, quality control and optimization of the performance of shotcrete.

Smart Engineering thus strengthens its position as a technical advisory company in advanced aspects of Structural and Materials Engineering. Smart Engineering engineers have high experience in the use and characterization of shotcrete, having also participated in the elaboration of different national and international regulations related to this material.

Smart Engineering participates in the design of the GFRC elements of the new Diagonal 0 Building

Smart Engineering participates in the design of the GFRC elements of the new Diagonal 0 Building

News

Smart Engineering has collaborated in recent months in the design and structural evaluation of the elements of GFRC (glass fiber reinforced concrete, for its acronym in English) that are being installed in the new Diagonal 0 Building, located at the beginning of Avenida Diagonal, in Barcelona. The Diagonal 0 building in Barcelona will consist of 26 floors that will house 89 luxury apartments. The design is led by the architect Odile Decq and its construction by ACCIONA. Its height will exceed 100 m and it will be part of the set of iconic buildings in Barcelona.

Its façade is made of fiberglass reinforced concrete (GFRC) elements, whose dimensions and geometry exceed the standards for the use of this type of material and for the wind loads (up to 350 kg / m2) at which they go to be subject during the useful life. Considering that there is no design regulation for this type of elements, and due to the high loads, the design, manufacturing and assembly aspects represent a challenge and a milestone both nationally and internationally in terms of the structural application of the GFRC.

The company EConcretus is in charge of the manufacture and installation of all the GFRC parts for the facade. Smart Engineering has verified the resistant suitability of the material as well as the structural safety of all the elements manufactured with this material. The uniqueness of the different pieces, as well as the emblematic of the building and the conditions in service, together with the lack of calculation regulations for this material, made this a totally unique project.

In this sense, Smart Engineering has carried out an intense work of structural modeling of the different manufacturing parts. The parts have been practically modeled in their entirety, using 3D finite elements, to verify the behavior of the material against the existing wind load and own weight requirements.

On the other hand, it has been necessary to carry out characterization tests of the material and of the manufactured parts. To this end, Smart Engineering has carried out tests at the Structures and Materials Technology Laboratory (LATEM) Lluís Agulló of the UPC as well as full-scale tests of the parts at the EConcretus facilities in Sentmenat (Barcelona).

The collaboration between EConcretus and Smart Engineering has allowed the design and manufacture of the GFRC parts for the building's façade, which stand out for having optimized dimensions taking into account the high service loads and the large number of parts a manufacture (most with different dimensions). The set has set a challenge and a new milestone in the use of this material for this type of application.

Smart Engineering produces a monograph on curing concrete structures

Smart Engineering produces a monograph on curing concrete structures

News

Last November, Smart Engineering completed the writing of the monograph “Curing of concrete structures: from theory to practice”, commissioned by the company Acciona Construcción. The objective of the aforementioned monograph is to deepen the practical knowledge of the topics of curing concrete structures, aimed at responding to the site technician responsible for this activity in any geographical circumstance.

The document lays the main foundations of what curing represents and the consequences derived from its incorrect performance. It also analyzes the main factors involved in the process, as well as different structural typologies and their circumstances from the curing point of view, both internal (concrete composition) and external (climatology and structural typologies). The document also proposes different models that can be applied by the project management. This knowledge is of vital importance both for site managers and for designers and technicians in general. The curing of concrete structures is a key aspect for the correct performance of structures during their service life, as well as to ensure their durability against external agents.

In many construction situations, either due to ignorance or due to lack of rigor, the minimum criteria regarding the practices necessary for the proper curing of the structure are not taken into account. All this leads to unexpected problems, such as early cracking of the structure, loss of mechanical performance or problems associated with durability. It is therefore pertinent and necessary to improve the knowledge available to technicians and designers, and this monograph lays those first bases of knowledge.

The development of this monograph lays the foundations for a new line of business for the Smart Engineering company, which carries out a knowledge transfer through monographs and training activities towards the main companies in the Civil and Industrial Engineering sector. In this way, the experience and knowledge of the technicians and engineers that make up Smart Engineering, both in the academic and professional world, are captured and the practice of companies in the construction, infrastructure and engineering sector is put into service civil.
