Problem: How do delivery logistics work in practice at the building site? Where are the big problems? How to make building logistics more effective? Do the site management and the haulers agree about questions concerning both parties? What is possible to gain by using better logistics? Is it possible to gain time with better logistics and by that reducing the costs? Purpose and aim: The purpose is to discover if there are any disagreements between the site management and the haulers. If disagreements occur they will be examined and probable measures based on the problems will be suggested. Another intention is to bring key ratios concerning time spent for deliveries forward. One aim is to update a similar report made in 1972. Another one is to clarify the big disagreements in order to make both parties aware of them. Method: We have with questionnaires tried to find out if the site management and the haulers have any disagreements. To see how the delivery logistic work we visited five different building sites and spent two days at each. Conclusion: - Deliveries stay in average longer at the building site than the site management and the haulers believe. - The haulers can save a lot of time if they early notify when they are going to arrive to the building site and then they did not have to wait while they are there. - If the site management had an organised plan concerning different things should be they could avoid unnecessary costs in damages. - If the building sites use a booking system for the machines they could avoid double booking.
