Abstract [en]

Electrical installations become a complex package to purchase, which largely depends on the structure of the electricity market. The market is characterized by oligopoly attributes, with a dominating price leader, followed by a limited number of players, and a not-working competition. The future trend among companies, in the construction industry, is to evolve Lean enterprise within planning towards industrializing the construction process. As for purchasing, it engages new thinking, in terms of innovations, developed from the individual process. The purpose of this thesis was to conclude how a construction company’s purchasing decisions should be advanced, with electrical installations as the object. The scope of this thesis is emphasized by the purchasing process of electrical installations, and factors that influence purchasing decisions. The thesis intended to provide the construction company with recommendations, of the identified purchasing strategies that should be progressed. A case study was performed at the Swedish construction firm, Nordic Construction Company. The company emphasizes on facilitating buildings, with good quality at lower costs. Integrating methods from Lean production with the construction process, resulted in a well-designed industrial construction system. It enables control and organization of both costs and resources. With this in mind, purchasing activities has shown to differ significantly from traditional construction building systems. The study began with a status report, that involved aspects of the construction industry, electrical market, problems with competition, and electrical installations. During the study, an observation and a workshop came to part. The study’s research approach was inductive, which intended to design purchasing strategies for the industrialized construction process. The starting point was existing theories such as, Lean production, Outsourcing, the purchasing process, structures of suppliers, and purchasing strategies. A qualitative method was chosen, to collect empirical data from interviews with people within the company, that were linked to the purchasing process and electrical installations. he steps in the purchasing process showed characteristics, such as fixed criteria, long term and fixed contracts with supplier of materials, reinvented purchasing and temporary agreements with electricians. Relationship oriented agreements, in terms of “partnering” with material suppliers and contractors, was a practice. The inspiring Lean building process, of standardization, the purchasing organization, supplier market, and structure, as well as its supplier relationships, was factors that influenced purchasing decisions. A need for well-developed purchasing strategies arose from disadvantages with the current material supplier. The resulting strategies emphasizes on one aspect of logistics, the central warehouse, the industrial building process benefited by obtaining "smart" products, and cooperating with manufacturers and OEMs is proven to gain profits. It is recommended to obtain partnership relationships, such as strategic alliances, with manufacturers or OEM, positioned below the current supplier. A recommendation is to advance with product innovations, to streamline installations and the construction process. It is recommended to design integrated and long-term agreements with contractors. Smaller electrical firms, with much to gain from cooperation, are identified as potential candidates. Another recommendation is to motion a specified certification, and to offer installations to a number of contractors, within locally geographic areas.
