Optimization and profitability are discussed a lot in construction. Experts believe that standstills and failures at a construction site take about 70% of performance. Now, solutions are sought which would provide a chance to be more economic, identify possible deviations in a project, and arrange the whole logistics chain smoothly despite the object under construction.<\/p>\n\n\n\n
AS E-Betoonelement, the service provider of construction of concrete elements, applies digital modelling (BIM\u2014Building Information Modeling) in the enterprise, which enables to test a building by software and to understand the possible \u201cbottlenecks\u201d of constructions even before the work actually starts on the site.<\/p>\n\n\n\n
Speaking of the advantages of using the digital model, the manager of the design department Jaanus Olop highlighted that all the material volumes are provided for the manufacturer in an elaborated model. As it is possible to enter the requirement of the materials to the software of the enterprise resource planning (the ERP system) automatically, there is no need to calculate any order of materials manually based on the drawings.<\/p>\n\n\n\n
\u201e\u00dchtlasti j\u00e4\u00e4vad \u00e4ra materjali k\u00e4sitsi sisestamisel tekkivad eksimused,\u201d lisab Olop, et mudelis on v\u00f5imalik pilte ekraanil igast nurgast p\u00f6\u00f6rata, mis v\u00f5imaldab planeerida montaa\u017ei j\u00e4rjekorda vastavalt projektis kasutatud s\u00f5lmedele.<\/p>\n\n\n\n
Kuna mudelisse on sisestatud ka ajafunktsioon, on v\u00f5imalik prognoosida materjalide vajadusi ajas \u2013 et materjalid saaks \u00f5igeaegselt lattu valmis tellida. Eelnevalt saab kontrollida, kui palju elemendid kaaluvad, mis v\u00f5imaldab kontrollida, et tellitav kraana oleks t\u00f6\u00f6de teostamiseks piisav. Lisaks teeb virtuaalne mudel mugavamaks ehitusprotsesside skeemide j\u00e4lgmise, loetleb Olop plusse. \u201eSelgust on rohkem ja vigade arv v\u00e4heneb.\u201d<\/p>\n\n\n\n
Marko Haabj\u00e4rv, the manager of the installation department, mentions that whereas the designers who use the programme daily have good skills, the ones who do not use BIM at a construction site on a daily basis are in danger of not rooting the skills of software handling and the efficiency might be little.<\/p>\n\n\n\n
Ehituses juhtub sageli, et asjaolud t\u00e4psustuvad ja on vaja t\u00f6\u00f6 k\u00e4igus projekti muuta. Olop r\u00f5hutab, et muutuste tegemisel on esmat\u00e4htis k\u00f5igile osapooltele teada anda mida ja milleks muudeti. \u201eMuudatuste m\u00f5jude anal\u00fc\u00fcsil on BIM mudel hindamatu abimees. Kuna koondmudelis on k\u00f5ik projekti osad, on hea hinnata, mida toob endaga kaasa \u00fche seina asukoha muutmine ventilatsioonitorude v\u00f5i teiste seadmete paiknemise osas ja ka vastupidi \u2013 kui torud viia teise asukohta, on mudelis kergest hoomatavad erinevad ristumised,\u201d r\u00e4\u00e4gib ta, et kui on soov talasid paigaldada, saab mudelist n\u00e4ha, kas need j\u00e4\u00e4vad hiljem kraanale ette. Elementide tellimisel on lisaks mugav kontrollida, kas elementide platsile tellimise j\u00e4rjekord on \u00f5ige v\u00f5i on kogemata j\u00e4\u00e4nud kahe tala alune post tellimusest puudu.<\/p>\n\n\n\n
\u201eKa on kergem m\u00f5jusid hinnata ja n\u00e4ha alternatiivseid variante,\u201c j\u00e4tkab Olop, kelle s\u00f5nul on oluline, et ehitusel oleks k\u00f5igil v\u00f5imalus BIM-i kasutada. \u201eOskus lugeda sisestatud infot ja teistele seda edsai anda, on v\u00f5tmet\u00e4htsusega k\u00fcsimus, mis eeldab nii projekteerija-, materjali valmistaja- kui ka ehitajapoolset kvaliteetset infosisestust.\u201d Nii v\u00f5iks igal projektil v\u00f5iks olla oma BIM koordinaator.<\/p>\n\n\n\n
Furthermore, BIM makes it easier to compile consolidated tables and to calculate the consumption of materials. \u201cI operate in the BIM system when calculating weights, specifying installation dates, and ordering concrete elements and other materials, where it is possible to extract the installation schedule and place orders in the production programme accordingly. This is our growth spot for us to assess the whole process more smoothly,\u201d mentions Haabj\u00e4rv. He admits that if the construction project is not theirs and it is managed by the office of a client, it is more complicated to handle changes and all the information. \u201cDuring the course of the project, it is asked in our own company if this or that works. However, it is difficult to provide feedback on other external projects. Especially if you have to provide all the information afterwards, the same person will not work with the next project, or information is not transferred sufficiently fast,\u201d he lists examples.<\/p>\n\n\n\n
\u201eBIM ei ole mingi imevahend,\u201d r\u00f5hutab Olop, kelle s\u00f5nul peavad protsessid paigas olema. \u201eSee on moodne t\u00f6\u00f6vahend, mis v\u00f5imaldab osasid asju lihtsamalt ja kiiremini teha.\u201d<\/p>\n\n\n\n
Olopi s\u00f5nul tekivad info liikumises \u201epudelikaelad\u201c ootamatutest faktoritest. Pigem muudab BIM ehitamisprotsessi digitaalseks ja v\u00e4hendab paberit\u00f6\u00f6d, tehes informatsiooni edastamise teistele projekti osapooltele kiiremaks ja t\u00e4psemaks. N\u00e4iteks, kui tootja on betoontoote \u00e4ra valanud, siis samal hetkel n\u00e4evad projekteerijad, ehitajad, tellijad \u2013 k\u00f5ik kellel on mudelile juurdep\u00e4\u00e4s, kogu infot. \u201eTellijale on see abiks rahavoogude planeerimisel ja v\u00f5imaldab kontrollida teostatud t\u00f6\u00f6de mahtu. Terve ehituse protsess l\u00e4heb l\u00e4bipaistvamaks, v\u00f5imaldades vanad projektijuhtimismeetodid muuta kaasaaegsemaks, uued ja v\u00e4hekasutatavad saavad rohkem s\u00f5na\u00f5igust.\u201c<\/p>\n\n\n\n
