  2. Abstract:
  3. As firms are facing with a new competitive environment which knowledge has a unique position, they should give more consideration to their employer's knowledge, and construction firms are not an exception. Employers are creating values for companies, and nowadays they are counted as strategic resources. In construction firms, due to their project based nature, workers are more important in creating values. One of the most essential elements of a construction firm is its ability to cope with social and environmental pressures to reduce waste and minimise the use of raw materials. To decrease wastes of Steel structure Construction, it is necessary to enhance the weld quality. Weld quality depends on many factors, and one of the most important of them is welder's effectiveness. From another point, it takes a long period of time and experience for an amateur welder to become a professional one. By using KM competences, workers' knowledge increases and tacit knowledge retains in the firm, and consequently quality of welding promotes, so waste of construction process such as wastes of materials, time, and project's cost mitigate. To determine how managers could use KM. According to APQC maturity road map, a survey study was done, also Delphi technique was used to understand experts' opinion, and exploratory research method was used to identify the principal components that explain influencing factors related to wastes welding. Principal component analysis (PCA) was used as a statistical method for data reduction. Finally 5 main categories (Welding Properties, Environment Condition, Educational Condition, welding Apparatus Condition, and Effect of Management) including 14 independent factors were obtained. It is recommended that steel structure firms' managers develop firms' KM strategy in accordance with these 14 factors to retain, develop, and share tacit knowledge of welders to reduce wastes of construction
