Abstract:Zaradi nenehnih pritiskov po skrajševanju rokov in zniževanju cen gradbenih storitev se podjetja na področju gradbeništva stalno soočajo s potrebo po večanju produktivnosti in ena izmed možnih rešitev je industrializacija gradbene proizvodnje. Industrializacija gradbenih procesov zahteva visoko stopnjo avtomatizacije in v tej točki se gradbena industrija sooča s številnimi problemi. Večina manjših in srednje velikih podjetij, ki v stroki prevladujejo, uporablja IT na zelo nizki stopnji. Še posebej so težave povezane z vzpostavitvijo in upravljanjem ustreznih informacijskih tokov, vzpostavljanjem interoperabilnosti med udeleženci in s tem povezanimi informacijskimi sistemi. V gradbeništvu se za potrebe izmenjave informacij o gradbenem objektu uveljavi koncept informacijskega modela zgradbe (Building Information Model – BIM). BIM gradbeni objekt opisuje celovito in nedvoumno ter v več dimenzijah. Je objektno zasnovan načrt zgradbe, ki vsebuje informacije o posameznih elementih – delih zgradbe – vključno z njihovimi atributi ter povezavami. Z uporabo BIM dosežemo enoten dostop do informacij za potrebe različnih panog, ki v gradbenem projektu sodelujejo. Vendar pa vpeljava koncepta modelno zasnovane gradnje v prakso kljub velikim naporom raziskovalcev in industrije še vedno ne poteka dovolj učinkovito. V pričujoči raziskavi smo opravili analizo obstoječe prakse upravljanja z informacijami o objektih ter analizo pristopov k prehodu iz tradicionalne v modelno zasnovano gradnjo. Kot orodje analize smo uporabili ogrodje, ki ga je v sklopu institucionalne teorije definiral Scott [Scott 2004] in v katerem so opredeljeni tipi nosilcev institucij. V analizi smo 2D načrtovanje obravnavali kot institucionalizirano obliko delovanja in preučevali njegovo togo vpetost v procese in metode, ki se uporabljajo v gradbeništvu. Želeli smo predvsem osvetliti razloge za stabilnost 2D pristopa v gradbeni in arhitekturni praksi. V drugem delu analize smo izsledke dveh izbranih velikih evropskih projektov umestili v splošno ogrodje procesa institucionalizacije povzetem po Tolbert & Zuckerjevem modelu [Scott 2007]. Namen tega dela analize je preučevanje sodobnih pristopov k prehodu v modelno gradnjo in postavljanje temeljev za boljše strateško odločanje pri nadaljnjem razvoju modelno zasnovane gradnje. Ključno vlogo za transformacijo gradbene industrije imajo mehanizmi, ki oblikujejo motivacijo za uvedbo sprememb, zato smo temu posvetili posebno pozornost in pokazali pomen ekonomskih učinkov v primerjavi s tehnično odličnostjo uvedenih rešitev. Osredotočili smo se še na v sedanji praksi manjkajoče vloge in druge organizacijske vidike. V zadnjem delu smo na študiju primera pokazali kako lahko spoznanja izvedene analize uporabimo pri inovacijskih procesih v gradbeni industriji. Razvili smo prototip celovite organizacijsko-informacijske rešitev za vpeljavo modelno zasnovanega spremljanja gradnje in upravljanje z materialnimi tokovi. Na osnovi analize vlog udeležencev in ustaljenih delovnih procesov smo pripravili model informacijskih preslikav, ki zagotavlja večjo transparentnost materialnega toka. Omenjena preslikava obravnava posplošitve posameznih gradbenih elementov na nivo tipa/vrste elementa, pri čemer je potrebno ločiti identiteto posameznega načrtovanega gradbenega elementa od identitete fizično izdelanega gradbenega elementa. Navedeno področje smo izbrali, ker med seboj povezuje prej slabo povezana segmenta masovne proizvodnje in inženirskega načrtovanja in ima zato velik potencial za uspešno vpeljavo novih pristopov. Po drugi strani je upravljanje materialnega toka eden izmed bistvenih virov neučinkovitosti gradbene proizvodnje, ki ga z uporabo obstoječih pristopov temelječih na 2D načrtih ni mogoče učinkovito izpeljati. Pri oblikovanju opisane rešitve smo se držali načela, da morajo demonstracijski projekti pokazati predvsem ekonomske učinke in ne prevladujoče tehničnih, saj je vodilni mehanizem sprememb v gradbeni industriji večanje pridobitev.

Title:Information flow optimization in construction projects as a basis for efficient information technology deployment strategy
Abstract:Construction sector is faced by constant demands for lowering prices and shortening project duration. Therefore the stakeholders are forced to search for any kind of productivity gain. One of the options that could be approached is industrialization of the production process in construction. However, industrialization requires high level of automation and on that point construction sector is confronted by many problems. Most of small and medium sized companies that prevail in the sector use information technology on the very basic level. Especially, the problems are related to information flows set up and management among the stakeholders and to information system interoperability issues. With regard to information exchange and collaboration in construction, the concept of building information modelling (BIM) has been developed as the most popular solution. The model describes buldings completely and unabigously in n dimensions. It is object oriented design of the building that includes information on particular parts of the building including all necessary attributes and relationships. With the BIM, different project stakeholders get standardized access to information regardless of their field of work. Despite the benefits and all the efforts made by the research community and the industry the concept of BIM is still not efficiently introduced into everyday practise. In our research, we have analysed current approaches in building information management and also we have analysed the methods used for transformation from traditional to BIM based construction. For the purpose of analysis we have used a framework developed by Scott [Scott2004] in scope of institutional theory, which defines types of institutional carriers and pillars. In the analysis, we have discussed traditional 2D design as an institutionalized way of working. From this point of view we have studied its rigid integration into methods and processes used in construction. The aim of this work was to put some light on stability of 2D design in architectural and construction rutines. In the second part of our analysis, we have evaluated two major European research projects related to transformation of construction sector into BIM based industry. The projects were put into framework of institutionalization developed by Tolbert & Zucker [Scott2007]. These efforts assess contemporary approaches in the development of the sector and search for better foundations of strategic planning and decision making in the field. Since key role in the transformation play mechanisms of institutionalization, which drive stakeholder motivation for change, we have put speciall attention to economic effects and compared them to technological excellence of new solutions. We have also identified missing roles and handled other organizational aspects. Exploatation possibilities of the research results have been demonstrated on a case study. We have developed a prototype of integrated organizational and information solution for BIM based project progress tracking and material flow management. Based on analysis of project roles and standard working procedures, we have developed a model of information mappings that assures higher thransparency of material flows. The mapping introduces generalization of particular material and construction elements to the level of element type and separates identity of particular designed element from phisicaly constructed elements. Selection of the problem that we approached in our case study has been influenced by our research results. The solution integrates two areas that were not tightly connected before the project and therefore holds high potential for acceptance of the new approach. On the other hand, material flow management is one of the major causes of inefficiency in construction and cannot be efficiently solved by using 2D design only. We have strictly followed the rule that demonstration project must show primarily economic benefits, because in construction sector increasing returns principle is the major mechanism of institutionalization
