In the company IN3PRENÖR and also generally in the construction industry, a lot of time is spent sorting out deficiencies and problems in construction documents between architects and suppliers during the design phase. The problem today is that the architects draw construction documents that do not correspond to the products that are on the market.

The purpose of this report has been to identify which deficiencies occur in construction documents between the architects and the suppliers and provide recommendations and improvements to the industry.

The extent of the report has been limited to the shortcomings that occur in construction documents during the design phase between architects and suppliers. Also the interviews have been limited to architects, suppliers and purchasers.

When compiling the interview study, it showed that the most frequent shortcomings in construction documents are that the proposed solutions are not compatible with the supplier's assortment and that custom solutions have incomplete drawings and shortcomings which can not be used for manufacturing. Modification of products often leads to the requirements not being met.

The most common reasons why there are deficiencies in the building documents have been compiled to. lack of inspection, lack of communication, lack of knowledge, lack of time, the public procurement act and it is also unclear what information is required in construction documents between architects and suppliers to ensure manufacturability.

Based on the causes and shortcomings, a number of different recommendations were compiled to the industry through the suggestions for improvement received by the interview study. Recommendations that the industry can use to minimize deficiencies in construction documents between architects and suppliers are that more communication is needed, better review of construction documents and clearer information from the supplier. This is summarized at the end of the report.
