Location Based Scheduling

The Location Based Scheduling (LBS) method is developed to help the construction industry with workflows and planning. The most common method in time and resource planning in construction is still today Critical Path Method (CPM). CPM has been the most dominating method since it was introduced in the late 1950. It has been proved an effective method for time and resource planning of projects. Thus, some critics have been raised about the CPM-method in relation to construction projects, as it is not sufficiently supporting construction management during execution and not to create a continuous and thus economical flow of resources. The LBS method is developed for the planning and management of workflows and could therefore be expected to be a viable alternative to CPM. The construction industry struggles with the subsequent delays and budget overruns and hopefully the LBS can help the industry to meet these challenges. The main philosophy about LBS is to create a tact in the construction projects. The different tasks in the projects need to go along in the same flow to create a constant progression without wasting time. To give an example: The carpenter can fix three apartments in one day. The next day starts the painter – but he can fix five apartments in one day. After one day has the painter catch up with on the painter and needs to stop his work until the carpenter has fixed more apartments. The main task is to divide the construction project into the right amount of locations. The Wiki article will describe how to divide a project into the right locations and how to manage the project with location based scheduling.

5.1 Article Type 1: Explanation and Illustration of a Method

[The articles are expected to adhere to the following structure:]

• Big idea: describe the tool, concept or theory and explain its purpose. The section should reflect the current state of the art on the topic
• Application: provide guidance on how to use the tool, concept or theory and when it is applicable
• Limitations: critically reflect on the tool/concept/theory. When possible, substantiate your claims with literature
• Annotated bibliography: Provide key references (3-10), where a reader can find additional information on the subject. Summarize and outline the relevance of each reference to the topic.

(around 100 words per reference). The bibliography is not counted in the suggested 3000 word target length of the article.

The Location Based (LBS) method is a graphical tool based on a technique developed by Karol Adamiecki in the early 20th century. Karol Adamiecki developed a schedule tool named harmonogram. This tool includes the location as a key element in the scheduling, in contrast to the Gantt Chart. There has been historical examples of the application of Adamiecki's concept. The construction work of The Empire State Building was one of the first projects that used location as main unit of analysis. The results were ground-breaking due to the fact that around 380 m2 were build per day of construction. The 102 levels were completed in 18 mounts with a significant low number of accidents for its date and under the initial estimated budget. </ref> Martinez, Natalia Rodriguez (2013) ‘Optimization of Flowline Scheduling vs.Balanced Resources and Task Continuity,</ref>
