The purpose of this master’s thesis is to derive knowledge of the main reasons for an increasing number of hidden errors and shortcomings of the complex installations of the technically complex buildings. As well as which business organizational conditions affect them, the overall construction process and subsequent operations.

The basic structure of the thesis is built around the Logical Framework Approach, which ensures a continuous structure throughout the thesis.
The Logical Framework Approach also provides space for structured analysis work.
The analysis in this thesis is two-part, the first part deals with a solution-oriented prerequisite, starting with the entrance hypothesis, the installation subjects are the forgotten subjects, according to management and coordination, in the efficiency of the construction process due to the author's experiences through the project-intensive stay of the education.
Wherever the entry hypothesis was tested in a wide field of knowledgeable stakeholders from the industry through qualitative semistructuring exploratory interviews that partially substantiated the entry hypothesis.
But to the same extent opened up to formulate the research questions of this thesis.
As well as allowing the author to participate in one of Danvak's theme meetings, dealing with the building board's approach to the area, where the author such as the fly on the wall had the opportunity to use this as a Qualitative Unstructured Focus Group discussion, resulting in the supply of a specialized knowledge that did not could be taken in a different way, as the participants presented a wealthy presentation of the developer, the professional engineer and the installation subjects, as well as the theme meeting allowed for rich discussion of the various problem areas and contexts.
This knowledge, along with macro and micro-environmental analyzes, has been compiled against a quantitative cross-sectional survey questionnaire, has been the basis for the development of a problem tree that links the found causes and effects to a major problem.
The complexity of the technical installations is overlooked in the technically complex buildings.
This problem tree is thus a basis for illuminating the Gap for a more desirable future for the industry.
This Gab becomes the basis for how this desired future could be achieved through the preparation of a target tree and Gap analysis last part.

Where the specialty reflects an industry where the complex installations of the engineering complexes are characterized by suboptimization and silo-thinking, which slowly but surely obscures the developer's project and operating economics.
Due to the prevailing culture, the cheapest price that has gradually created fouling in all the corners of the industry.
How the old approach with "due diligence" has been replaced by cold economy thinking.
Where otherwise skilled designers and project managers at all levels forget that the builder is far from professional and therefore needs adequate advice that leads it safely throughout the entire construction process.
The gain for the industry has potentials if this succeeds to be great if all professional partners stop focusing on what is best for their own business, but instead takes the starting point of the classic TQM approach that puts the project and thereby builder in the center.
Why there is a need for interdisciplinary leadership that culminates in the classic silo thinking and binds all project processes together to create value by removing the unnecessary interfaces between the different silos.
How the industry's most valuable product, knowledge, is used fully and not just knowledge from those with the highest education.
How valuable knowledge, experience and skills can pave the way for better and cheaper projects for all, which in turn can positively reflect in the builders' long-standing after-sales operations.

Thus, the second part of the thesis is designed to ensure this approach through a classic LFA matrix that requires all the lowest common denominators to be met before the overall process can rise to the next level.
In addition, it has been chosen to use an almost unknown academic decision-making, which is based exclusively on benefits, to ensure that the developer is dressed to make the right overall contract, collaborative and quality decision in a simple and manageable manner.

This thesis concludes that the real issues of the complex installations of technically complicated buildings is an industry where sub-optimization and silo-thinking are a 'big part of the game' and the client' project- and operating economies are suffering. Because of a culture that ensures that the industry, not the client, gets the most value for his money. In order to solve this, it is imperative for a total quality management attitude, but this requires major changes to the industry's current standards, behavior and culture. To where skilled project managers at all levels are at the forefront of projects and through professional advice from the builder, ensure that it is conducted safely throughout the entire construction process. The winnings, if successful, can turn out to be really great if all partners stop focusing on what is best for their own business, but instead takes the starting point of TQM, putting the project and thereby the builder into focus. As the complex installations of the technically complex buildings rises steadily, and the many involved partners increase the risk of unfinished border areas, due to the lack of clarification and division of responsibilities. Why there is a need for interdisciplinary leadership that makes up with the classic silo thinking and binds all project processes together to create value by removing the unnecessary interfaces between the different silos.
