Analysis and performance measurement of construction logistics / Analys och utvärdering av logistik vid byggandet av kvarteret Spinnrocken i Norrköping

Lohm Isberg, Maximilian, Olsson, David January 2013 (has links)
The construction industry is a business with an intense flow of both material and information that require well-functioning logistics in order to not suffer from unnecessarily high costs. Suppliers play a big part regarding the costs of the distribution and handling of material and due to this a construction project’s costs are affected a great deal by the suppliers’ actions. Spinnrocken is a construction project in the town center of Norrköping. The real estate company Fastighets AB L E Lundbergs is the client and the construction company Skanska is contracted as sole constructor for the project. Spinnrocken is planned to be finalized in the summer of 2014 and consists of several rental-apartments and some smaller businesses. Spinnrocken and its central location result in major logistic challenges, because of this Lundbergs and Skanska want to analyze and evaluate the project’s logistic performance. The main purpose of this thesis is to measure the order fulfillment of interior materials, the scaffold material Doka and windows at Spinnrocken by using the so-called perfect order fulfillment measure, as defined in Supply Chain Operations Reference Model. Perfect order fulfillment indicates the delivery performance to the construction site.The combined perfect order fulfillment for the three investigated materials is 18 %. A perfect order fulfillment of 18 % means that only one out of five inspected deliveries to Spinnrocken was considered having no faults at all. The effects of a low perfect order fulfillment are disruptions in the short-term time schedule, delayed operations, additional work and that the work space at the construction site is occupied by unnecessary construction material. The resulting effects thereby affects the project’s economy negatively.

Förbättring av leveransprestation : En fallstudie av orderprocessen i ett uthyrningsföretag inom byggbranschen / Improving delivery performance : A case study of the order fulfillment process in a rental company in the construction industry

Garcia Wernersson, Rikard, Lund, Eric January 2017 (has links)
En undermålig leveransprestation av maskiner och utrustning skapar problem i hela försörjningskedjan för ett byggprojekt. Ifall maskiner och utrustning inte levereras efter överenskommen tid, bidrar det till stillestånd och förseningar av byggprojektet. Bygget stannar upp om inte rätt maskiner, finns på rätt plats, i rätt skick och i rätt kvantitet. Syftet med studien är att identifiera vilka moment som tillsammans utgör orderprocessen i uthyrningsbranschen och vad som påverkar tillförlitligheten av leveranser för uthyrning av maskiner och utrustning till byggbranschen. En processkartläggning har identifierat fem moment i orderprocessen, kundkontakt, ordermottagning, orderhantering, leverans och returer. För att veta hur väl orderprocessen presterar behöver mätetal införas. Utan mätetal är det svårt att veta ifall maskiner och utrustning levereras efter vad som överenskommits med kund. Mätetal underlättar även för förbättringar i processer då det går att jämföra mot tidigare mätetal för att se ifall en förbättring har blivit en förbättring eller enbart en förändring. En kombination av mätetal på tillförlitlighet från Supply Chain Operations Reference Model samt tillämpningar och metoder från Supply Chain Management kan förbättra tillförlitligheten av leveranser i en försörjningskedja som förser byggbranschen med maskiner och utrustning. / A poor delivery performance of machines and equipment creates problems throughout the supply chain for a construction project. If machines and equipment do not arrive in compliance with agreed upon time, it will cause downtime and delays at the construction site. The construction site will come to a standstill if not the right machines is at the right place, at the right time, in the right condition and in the right quantity. The purpose of the report is to identify which elements constitute the order process for rental of machines and equipment, as well as provide suggestions on how the elements can be improved to increase the reliability of deliveries to and from construction projects. With process mapping five elements of the order process have been identified, customer support, receiving of orders, processing of orders, deliveries and returns. To know the performance of the order fulfillment, measurements need to be introduced. Without metrics, it is difficult to know if machines and equipment arrive at the construction site correctly. Metrics also facilitate improvements in processes as it is possible to compare to previous measures to see if an improvement has been an improvement or just a change. If metrics on reliability from the Supply Chain Operations Reference Model is combined with practices and methods from Supply Chain Management the reliability of deliveries in the supply chain that supplies the construction industry with machines and equipment can be improved.
