With the creation and continuous enhancement of Computer Aided Design (CAD) software, innovations in the area of computer modeling for the construction industry have brought numerous benefits in terms of precision, operability, extensibility, and time-cost savings, among others. Nevertheless, the construction industry is one which continually demands innovation and efficiency in design, leading to the introduction of newer modeling approaches to satisfy client needs. The central thinking behind this research, then, has to do with the automation and generation of construction drawings for the home building industry based on 3D and parametric modeling techniques, and the utilization of the best practice for the platform-frame method. Homebuilders in Canada often build without construction drawings due to the high cost and extensive time expenditure associated with their production; instead, the industry relies on trades personnel to build from architectural model designs. This poor practice contributes to the accumulation of material waste and other construction quality issues. The underlying basis for this research is the notion of adding structure to information, both by incorporating intelligence into a set of operational commands and by adding innovation to the construction process. These topics have been incorporated into a 3D CAD solid model to demonstrate the importance of communicating information from consultants to trades and contractors. 3D and parametric modeling provide the foundation for this complex analysis, which focuses on the generation of panelized and site-built dwellings. The minimization of construction wood materials through the use of mathematical models and a search for best combinations of nominal lumber, sheathing and drywall has been added to this research as an aim to become more efficient. Mathematical optimization models are used to verify the concept for efficient cutting layouts for one- and two-dimensional elements. This research sets out to demonstrate, by underscoring the present shortcomings, the manner in which 3D and parametric modeling will provide a solution for practitioners and researchers who wish to reduce drafting time and material waste production; to incorporate intelligence to CAD models; and to provide a better use of primary resources by generating guidelines for construction practice. / Construction Engineering and Management

Att spara tid och resurser är något som är av stor vikt i dagens byggbransch. Ju snabbare ett arbete utförs desto mer pengar tjänar företaget. I detta examensarbete har författarna tittat på effektivisering av ritningshanteringen i olika delar av byggbranschen. Att kunna hitta bland ritningarna på ett enklare sätt och att slippa sortera ut gamla ritningar när nya kommer in, är något som skulle förenkla ritningshanteringen och snabba upp tempot. Författarna har tittat på programmet DDR – Databas för Detaljer och Ritningar, som de anser kan förenkla ritningshanteringen. Under arbetets gång har intervjuer hållits med olika personer inom byggbranschen för att se förbättringsmöjligheter och nyttan av ett sådant program. Resultatet av arbetet visar att programmet DDR skulle göra mest nytta på byggarbets-platser och inom förvaltning då det är inom dessa områden som ritningshantering utförs mest. Programmet DDR kan förkorta tiden det tar att bläddra bland ritningar med uppskattningsvis 25 % enligt de intervjuade på byggarbetsplatserna, vilket skulle kunna innebära en markant skillnad i det dagliga arbetet. Om övergång sker helt till digitala ritningar 1 skulle behovet av att sortera ritningar elimineras och ännu mer tid kan sparas. För att göra så stor skillnad som möjligt på dagens marknad måste de förbättringar som framkommit under intervjuerna utvecklas till programmet DDR. Som det är idag saknas många funktioner vilket gör att konstruktionsföretagen inte vill använda programmet DDR på grund av avsaknaden av möjlighet att lägga in egna detaljer. Förvaltning anser bland annat att flera viktiga mät- och ritfunktioner saknas i programmet DDR för att vilja använda det. Kalkylerare och kommuner ser ingen framtid alls för programmet DDR inom deras verksamhet. Undervisning på högskola och i produktion på byggarbetsplatser anser att bland annat zoomningen och panorering måste göras enklare, trots detta är de intresserade av att använda programmet DDR. / Saving time and resources is something that is very important in construction business today. The faster a work can be done the more money a company can make. In this degree project the authors have looked at the process of handling construction drawings in different parts of the construction industry. To be able to find the construction drawings in an easier way and not have to sort out old construction drawings when new arrive is something that may simplify and speed up the process. The authors have looked at the application DDR – Database for Details and Drawings, which they consider could simplify the process of handling construction drawings. During this degree project, interviews have been done with different people in the construction industry to see possibilities of improvement and benefits of the application DDR. The result of the degree project shows that this application would make the most difference on construction sites and within management of buildings since these are the ones that handle construction drawings on a daily basis. Application DDR can shorten the time used for handling of construction drawings by approximately a 25% decrease according to the interviewed at the construction sites; this would make a great difference in the daily work. If they only use digital construction drawings, the needs to sort out old construction drawings when new ones arrived, will be eliminated and more time can be saved. To do as much of a difference as possible on today’s market the improvements that have emerged during the interviews have to be developed to the application DDR. As it is today there are many features that are missing which make that the construction companies won’t use the application due to the lack of possibility to add details on their own. Management of buildings considers that there are several important functions such as measuring and drawing that are missing to use the application DDR. Within calculation engineering and municipalities there is no future for the application DDR. Education at college and in the production of construction sites consider that zooming and panning must be made simpler, despite this they are interested in using the program DDR.

The subject of the diploma thesis is the geodetic survey of historical part of Dominican monastery in Znojmo city and to create documentation of the building. The thesis contains a description of the place of interest, preparation for work and measuring process. Next part the thesis deals with the requirements of creating the drawing documentation of the ground plan and the vertical section and also testing results of the work. The final documentation will be used for the reconstruction of the building.

Arbetet dimensionerar ett panelsystem för att motstå yttre påfrestningar som snö och vind, samtidigt som att det ska erbjuda oförstörande av- och påmontering. Hållfasthetsberäkningar har utförts med hjälp av statiska balkfall. Dimensionering av spår, snäppfunktion och låsningar i profilsystemet har utförts. Konstruktionsritningar har utförts, baserade på dimensionering och standarder. Med hjälp av detta arbete går det att tillverka detta system, åtminstone i ett prototypstadie. / This work dimensions a panel system to withstand external loads such as snow and wind, while it will offer non-destructive removing and assembly. Strength calculations have been performed using static beam cases. The design of the track, the snap-fit assembly and locks in the profile system has been changed. Construction drawings have been made, based on the calculated dimensions and required ISO-standards. With the existing work, it is possible to manufacture this system, at least in a prototype stage.
