The door and its surrounding, is an important part of all buildings. It often amount to a significant part of buildings total costs. The more demands of functions the largerdoes the costs grow. The purpose of this report is to analyze those demands and how to fulfill them. Another purpose is to examine of which reasons the cost grow and how to avoid it inthe best possible way. The study will be performed in collaboration with Bjerking AB. To define the demands a literature study will also be performed. The essential part however will be interviews with persons with different employment regarding doors. The literature study shows the demanding are very different depending on several aspects. Those could be such things as the number of people passing and how the building is meant to be used. The results of the interviews shows doors and their surroundings are very complicated. The reasons are many. One of them is that persons are limited to their own employment and don’t have the knowledge to see the full context. Increased communication is a solution to that problem among others. With increased knowledge it’s possible to select better and cheaper solutions. Such solutions is about both choosing products and planning buildings design. There seem to be possible to develop doors and its surroundings in several ways. The interviewed persons often mention the door closer as one product they would likedevelopment in. It’s important it closes hard enough but it makes the door heavy to open since both forces often are equal. The problem today in developing better products is to find a participant willing to paythe cost the development requires.

Today’s construction buildings contain more advanced technologies than before. The development of newer and stricter regulations to the construction industry makes the door environment more and more complex. In large construction projects the door environment is held up as a major challenge to get to in a good way. It turned out after a discussion with one project manager and a site manager at NCC, that the door environment is difficult to get right in major construction projects and it often causes many error reports in to the aftermarket after that the final inspection is completed. Interviews have been done with key figures in the building process at NCC and Akademiska hus. A study on a university building for around 3500 students and with 300 workplaces was made. There were a lot of data with fault reports to the go trough to find fault report from doors and be analyzed and statistic. The results from the data collection showed that many fault messages on the doors in was caused by the door operator. And from the interviews the content was clear that the coordination has to be good to have a functioning and a good door environment. One part that can contribute to a better door environment is to plan space for possible door operator over the door. Another part is that the construction documents which production workers are working with, is to find a way to always have the latest documents in hand.

Syfte: Kommunikationsproblem leder årligen till miljontals kronor i extrakostnader inom byggbranschen. Dörrmiljön utgör ett viktigt moment inom byggnationen där de många inblandade aktörerna skall kommunicera korrekt och i tid för att uppfylla de höga funktionskrav som dörrmiljön innefattar. Syftet med rapporten är att beskriva dörrmiljöns komplexitet, undersöka och redogöra för de huvudsakliga problemområdena som uppstår kring arbete vid dörrmiljön, samt utveckla möjliga lösningsförslag inom området. Metod: Studien har genomförts som en explorativ fallstudie där dörrmiljöns komplexitet anses vara representativ för och återkommande inom husbyggnadsindustrin. Data samlas in genom intervjuer med byggproduktions- och arkitektpersonal samt ett enkätutskick. Resultat: Genom studien har en kartläggning över dörrmiljön tagits fram som belyser och klargör för den mångfald av komponenter och aktörer som dörrmiljön innefattar. Insamlade enkätdata visar att cirka 80 procent av studiens respondenter upplever problem med dörrmiljön i varje eller de flesta projekt. Vidare har ett flertal problemområden identifierats, såsom försvårad erfarenhetsåterföring, undermåliga kravställningar och motstridande funktioner. Dessa områden har analyserats tillsammans med etablerad teori inom bland annat projektledning och kommunikation. Slutligen mynnar studien ut i lösningsförslag kring hanteringen av dörrmiljön. Både etablerandet av en ny samordningsdisciplin och utvecklandet av ett digitalt verktyg som samlar all information kring dörrmiljön diskuteras som potentiella alternativ. Konsekvenser: Dörrmiljön utgörs av en stor mängd komponenter och aktörer på en relativt liten yta. Den är en intrikat detalj från projektering till färdig installation vars helhet och fulla funktion riskerar att undgås av många av de inblandade parterna. Vidare utgör dörrmiljön ofta ett icke-prioriterat moment som saknar centraliserad samordning. För att bemöta dörrmiljöns komplexitet bör den projekteras i ett tidigt skede där alla berörda parter involveras. Begränsningar: Undersökningen begränsas till att studera arbete och rutiner inom projektering samt dess konsekvenser i produktionssammanhang. Sålunda studeras inte tillverkning, inköp, arbetsledning i produktionsfasen eller eftermarknadskonsekvenser. Vidare innebär den explorativa fallstudien att en stor del av resultatet är ny information som saknar bekräftande av tidigare undersökningar. I och med att undersökningen baseras på intervjuer och enkätsvar är den data som studien gett upphov till grundad på människors uppfattning och erfarenheter av verkligheten. / Purpose: Issues regarding communication annually generates millions of Swedish crowns in excess costs within the housing construction industry. The door – with its surrounding installations and functions – make up an important building element in which a multitude of actors require functional communication in order to fulfil its requirements. The purpose of this paper is to describe the complexity surrounding doors, to explore and explain the main problems related to the planning and installation of doors, as well as to develop feasible solutions for these problems. Method: The study is composed of an explorative case study in which the complexity surrounding doors is to be regarded as representative for and typical within the housing construction industry. Data is collected by interviewing production managers and architectural engineers, as well as by a digital survey. Findings: The multitude of components and actors associated with the planning and installation of doors are charted throughout the study. According to the survey within the study, approximately 80 percent of its respondents have experienced door-related issues in either every or most projects. Furthermore, several points of interest are identified as problematic regarding the planning and installation of doors, such as challenges with the storing of knowledge, insufficiently formulated demands, and conflicting functions. These points of interest are combined with established theories within, among other areas, project management and communication. The study resulted in two discussions regarding the handling of doors; the development of digital tools and the establishment of a new consulting role, coordinating the process behind planning and installations of doors. Implications: The door and its surrounding environment depend on many components and professionals. It makes up an intricate detail from early planning to final installation which full extent risks to elude the many actors involved. Furthermore, the importance of the area is often neglected and lack central coordination in project management. To counteract this complexity, the planning regarding doors must be prioritized early in the process and all affected actors should be involved. Limitations: The study is limited to work sets and routines associated with the planning process and its consequences in the context of the production process. Thus, the component production and procurement process, construction supervision and service and management process are not included in the study. Furthermore, the explorative nature of this case study partially amounts to new information that has not been confirmed in previous studies. As the study is achieved using responses from interviews and a survey, the data presented is based on people’s perception and experience of reality.
