eConstruction diary
No full textU završnom radu objašnjen je pojam e-Građevinski dnevnik. Osnovna razlika između dnevnika koji se vodio na papiru i sadašnjeg elektroničkog je ta što se za pokretanje e-Građevinskog dnevnika na početku moraju unijeti svi podaci o sudionicima u gradnji, njihova ovlaštenja, svi potrebni dokumenti kao što su građevinska dozvola, prijava početka građenja, izjave o svojstvima, projekti. Građevinski dnevnik može pokrenuti samo osoba koja ga je i kreirala. Ostali sudionici dobivaju poziv za sudjelovanje u projektu, tj. ispunjavanju dnevnika, i trebaju prihvatiti poziv nakon čega mogu unositi podatke. e-Građevinski dnevnik vodi izvođač radova uredno i ažurno, a potpisuje ga nadzorni inženjer. U dnevnik se ažurno upisuju podaci za svaki radni dan (kakvo je vrijeme bilo taj dan, koliko je bilo radnika, koji strojevi su se koristili, koji radovi su se izvodili) i završavanjem unosa nije više moguće prepravljati unesene podatke. Stranica dnevnika je završena kada ju nadzorni inženjer potpiše. Nadzorni inženjer može postaviti rok za popunjavanje stranica dnevnika. Građevinski dnevnik potpisuje se kvalificiranim elektroničkim potpisom. Prije zatvaranja dnevnika, nadzorni inženjer kreira završno izvješće.This Bachelor Thesis is explaining the term e-Construction diary. The main difference between the diary that was kept on paper and the current electronic one is that, in order to start the e-Construction Diary, at the beginning, all the data on the participants in the construction, their authorizations, and all the necessary documents such as the building permit, notification of the start of construction, and certificates must be entered. The construction journal can only be started by the person who created it. The other participants receive an invitation to participate in the project, i.e. to fill in the diary, and must accept the invitation and then enter data. The e-Construction Diary is kept by the construction contractor in an orderly and up-to-date manner and is signed by the supervising engineer. Data for each working day are entered up-to-date in the diary (what was the weather like that day, how many workers were there, which machines were used, which works were performed), and by completing the entry, it is no longer possible to modify the entered data. The log page is complete when the supervising engineer signs it. The supervising engineer can set a deadline for completing the log pages. The construction diary is signed with a qualified electronic signature. Before closing the logbook, the supervising engineer creates a final report
Traditional carpentry joints seismic testing
No full textOvim radom obratili smo pažnju na tradicionalna drvena krovišta koja su većim djelom zastupljena na našem području te su izvedena od običnih drvenih elemenata a spojevi su najčešće tesarski sa ili bez ojačanja. U ovom diplomskom radu ispitat će se mehaničko cikličko ponašanje drvenih spojeva. Na primjeru spoja rogova s veznom gredom analizirat će se njegovo ponašanje numerički i eksperimentalno u monotonim i cikličkim uvjetima. U svrhu diplomskog rada izrađena su tri modela s kutevima od 30°, 45° i 60° između roga i grede. Ukupno je provedeno šest ispitivanja, tri na neojačanim modelima i tri na ojačanim modelima, kao ojačanje koristili smo metalnu ploču. Rezultati ispitivanja odnosno pushover analize prikazani su grafički u odnosu sila/pomak (krivulja F/d). Numerički proračun bit će prikazan pomoću programskog paketa SCIA Engineer. Modelirat će se krovište u 2D-u pri čemu će se mijenjati veza između roga i grede.In this paper, we focus on traditional wooden roofs that are predominantly found in our area and are constructed from ordinary wooden elements, with joints that are usually carpentry joints, with or without reinforcement. This thesis will investigate the mechanical cyclic behavior of wooden joints. Using the example of the connection between the rafters and the tie beam, its behavior will be analyzed numerically and experimentally under both monotonic and cyclic conditions. For the purpose of this thesis, three models have been created with angles of 30°, 45°, and 60° between the rafter and the beam. A total of six tests were conducted: three on unreinforced models and three on reinforced models, using a metal plate as reinforcement. The results of the tests, specifically the pushover analysis, are graphically presented in relation to force/displacement (F/d curve). The numerical calculations will be performed using the SCIA Engineer software package. The roof will be modeled in 2D while varying the connection between the rafter and the beam
Architecture and urban design of Retfala south business zone
No full textPoslovna zona Retfala smještena je na južnom ulazu u grad Osijek. U zoni je predviđeno devet poslovnih zgrada s javnim i ozelenjenim prostorom te šetnicom koja ih povezuje. Poslovna zgrada nalazi se na sjevernom dijelu obuhvata, u nizu lamela. Glavna ideja vodilja pri projektiranju zgrade bila je prilagodba okolini u kojoj se nalazi. Zgrada tako ostvaruje interakciju sa šetnicom koja prolazi uz njezin južni dio, dok se istovremeno distancira od bučnog i neprivlačnog sjevernog dijela. Prostor zgrade obogaćen je otvorenim, ekstrovertnim zonama, što je dodatno naglašeno zatvorenim kubusima koji sadrže prostore introvertnog karaktera.The business zone Retfala is situated at the southern entrance to the city of Osijek, with plans for nine business buildings accompanied by public and green spaces, as well as a promenade connecting them all. The office building is positioned in the northern part of the complex, forming part of a series of slats. The central design principle of the building was to respond to its surrounding environment. As a result, the building establishes a connection with the promenade along its southern side while distancing itself from the noisy and less appealing northern side. The structure incorporates open, extroverted spaces, accentuated by enclosed cubes that house spaces with an introverted character

Building Information Modeling—Empowering Construction Projects with End-to-End Life Cycle Management
No full textThe construction industry has been significantly transformed by the implementation of Building Information Modeling (BIM), which has facilitated extensive project management capabilities across the entire life cycle. Notwithstanding its advantages, there exist certain limitations that hinder its extensive implementation. This study aims to investigate the disparities related to the adoption of Building Information Modeling (BIM) by conducting a thorough analysis of factors such as data interoperability, standardization, collaboration, skill gaps, and resistance to change. The data were collected through a preliminary pilot survey and a primary questionnaire. The collected data were then subjected to analysis using two statistical techniques: Exploratory Factor Analysis (EFA) and Partial Least Squares Structural Equation Modeling (PLS-SEM). This study reveals noteworthy associations between the adoption of Building Information Modeling (BIM) and several crucial factors, including Continuous Integration (CI), Monitoring and Control (MC), Project Management (PM), Resolution and Performance (RP), Structural Management (SM), Sustainability Administration (SA), and Value Management (VM). This study provides valuable insights for professionals and policymakers, offering recommendations to enhance the implementation of Building Information Modeling (BIM) and advocating for additional research on complementary factors. Through the identification and subsequent resolution of recognized shortcomings, Building Information Modeling (BIM) can be employed in a proficient manner to augment collaboration, mitigate costs, optimize energy efficiency, and implement sustainable construction methodologies. The present study makes a substantial contribution to the progress of Building Information Modeling (BIM) adoption and the efficient management of construction project life cycles
Challenges in Sewer System Maintenance
No full textA sewer system is an important infrastructure of every settlement. A sewer system is a set of construction facilities used for the quick removal of wastewater from the humans’ immediate environment and its transport to a wastewater treatment plant or direct discharge into an appropriate recipient. In order for the sewer system to perform its purpose properly, its proper maintenance is required. Maintenance of a sewer system is very demanding since the system is mostly underground which makes it difficult to be accessed and maintained. The maintenance of a sewer system can be preventive (regular) or corrective (reactive). The regular maintenance occurs at certain intervals, whereas the reactive maintenance occurs in the case of some unforeseen event. This paper presents the history of sewer systems, as well as basic and alternative types of sewer systems. Furthermore, challenges that arise during sewer system maintenance and difficulties that maintenance employees face in their work are presented in this paper, as well as the ways in which sewer systems are maintained
Manufacture of semi- montage interfloor structures
No full textU ovom radu će se opisati tehnologija izvođenja polumontažnih međukatnih konstrukcija, materijali i strojevi koji se pritom koriste. Međukatne konstrukcije su nosivi horizontalni elementi u konstrukciji koji preuzimaju opterećenje od elemenata iznad sebe te to isto opterećenje prenose na zidove ili stupove ispod sebe. Međukatne konstrukcije ujedno daju i zaštitu od buke, vlage, toplinskih gubitaka i požara. Također međukatna konstrukcija dijeli zgradu po etažama. Može biti izrađena na nekoliko osnovnih načina, a to su: monolitni, montažni i polumontažni. U ovom radu će se najviše govoriti o polumontažnon načinu izrade od kojeg su pojedini dijelovi izrađeni u tvornicama te se kao gotovi elementi dovoze na gradilište i ugrađuju, a neki elementi se izrađuju na mjestu ugradnje pa ga upravo zbog takvog kombiniranog načina izrade zovemo polumontažni. Kada se govori o polumontažnim vrstama konstrukcija tu je potrebno spomenuti da su najzastupljeniji monta i fert, te Ytong koji se u zadnje vrijeme sve više koristi. Najistaknutije prednosti polumontažnih međukatnih konstrukcija bi bile brzina ugradnje, cijena, jednostavnost rada i tehnologije izvođenja.This work will describe the tehnology of semi prefabriced interfloor construction, the materials and machines that are used. Interfloor structures are load-bearing horizontal elements in the structure that take the load from theelements above them and transfer the same load to the walls or columns below them. Interfloor structures also provide protection agains noise, moisture, heat loss and fire. Also, the interfloor structures devides the building into floors. It can be made in several basic ways, namely: monolitic, prefabriced, semi assambled. In this work we will mostly talk about the semi-prefabriced manufacturing method, from which some parts are made in factories and are bought to the construction site as finished elements and installed, and some elements are made at the installation site, so it is preciely because of this combined manufacturing method that is called semi-prefabriced. When we talk about semi prefabricated types of construction, it should be mentioned that the most common are monta and fert and ytong, which has been used more and more recently. The most prominet advantages of semi
prefabricated interfloors structures would be the speed of installation, price, ease of operation and execute tehnology
Architecture and urban design of Gacka business zone
No full textZgrada se smješta na zapadnom dijelu kompleksa te svojim postavljanjem komplementira ostale zgrade i stvara fluidan put i ostavlja prostor za središnji trg koji je centar komunikacije korisnika. Na pročeljima vidimo prošupljenja zgrade na kojima se zasniva koncept. Pomoću deformacije stvorena je igra volumena i masa unutar samog ograničenog okvira zgrade. Svaka etaža ima svoju priču i putanju, kako bi uistinu razumjeli ovu zgradu moramo ju razgledati i izvana i iznutra. Izvana vidimo udubine i igru raznim bojama stakla kojom se ističe ta stalna promjenjivost, neočekivanost i zbrka svakodnevnog života, a kontrast predstavlja statičan grid stupova i greda koji dovodi u red cijelu tu priču.
Unutar zgrade imamo snažne uzdužne horizontalne komunikacije uz koje se nepravilno nižu različiti sadržaji. Zgrada ima korijene u metabolizmu, skeletna konstrukcija joj daje mogućnost budućeg širenja i lakog premještanja pregradnih zidova i stvaranja potpuno novog prostora.The building is located in the western part of the complex and its layout complements other buildings and creates a fluid path and leaves space for the central square which is the center of communication of users. On the facades we see the hollows of the building on which the concept is based. With the help of deformation, a game of volume and mass is created within the limited frame of the building. Each floor has its own story and trajectory, in order to truly understand this building we need to look at it both outside and inside. From the outside, we see indentations and play with various colors of glass that highlight this constant changeability, unexpectedness and confusion of everyday life, and its contrast is the static grid of pillars and beams that brings order to the whole story. Inside the building we have strong longitudinal horizontal communications with
which various contents are irregularly arranged. The building has its roots in metabolism, the skeletal structure gives it the possibility of future expansion and easy relocation of partition walls and the creation of a completely new space
Architecture and urban design of Gacka business zone
No full textTema završnog rada je urbanističko i arhitektonsko rješenje poslovne zone Gacka. Urbanizmom se definirao položaj
markica poslovnih zgrada koje će se nalaziti na jednoj parceli, a čije će podzemne etaže biti povezane jednom zajedničkom
garažom. Koncept arhitektonskog rješenja nadovezuje se na prvotno postavljene ciljeve urbanističkog rješenja. Ciljevi su ostvariti
sinergiju i stvoriti više zajedničkih prostora. Zbog velikog koncentracije ljudi. Korisnici imaju usmjeren put kretanja dijagonalom
odnosno šetnicom. Položaj svih planiranih poslovnih zgrada osmišljen je tako da se otvara korisnicima ka središtu parcele, a okreće
od divlje gradnje i velikih infrastrukturnih sustava. Buku koja dolazi od velikih prometnica planirano je blokirati zaštitnim visokim
zelenilom na obodu parcele. Poslovna zgrada nadovezuje se na urbanizam te sadržava otvoreno prizemlje i prolaz. Zgrada je
podijeljena na dva dijela puno/prazno. Podjelom zgrade postignuto je logično i brza komunikacija. Tlocrtni koncept očitava se i na
fasadi. Na otvorenom dijelu zgrade je dvostruka staklena fasada te se zgrada doima providno. Na suprotnom, zatvorenom dijelu
zgrade je fasada od šuplje opeke.Topic of the final paper is the urban and architectural solution of the Gacka business zone. Urban planning has defined
the position of stamps of office buildings that will be located on one plot, and whose underground floors will be connected by a common garage. The architectural solution deals with the project of one of the business buildings from the scope of the conceptual urban solution. The concept of the architectural solution builds from the originally set goals of the urbaqn solution. Main goals are to achieve synergy and create more common spaces. Due to the large contetration of people, users have a directed path along a diagonal. The locaton of all office buildings is designed to open to users towards the center of the plot, and turn away from illegal construction and large infrastructure systems. Tall greenery on the perimeter of the plot is planned to protect the site from the noise coming from major roads. It also contributes to the aesthetics of the ground floor and the view from the buildings. The office building is a continuation of urbanism and contains an open ground floor and passage. The building I split in two parts full/empty. The concept drives idea from the urban solution where the building is facing inwards. By dividing the building, logical and fast communication was achieved. The floor plan concept can be read on the facade. The open part of the building has a double glassfacade and the building looks transparent. On the opposite, closed part of the building is a hollow brick facade
