Development project: The impacts of an construction logistics center on the efficiency and work environment of construction projects

City of Stockholm conducts, together with the construction company Viktor Hanson AB, a study to examine how BLC affects the work site.
The study will run from autumn 2013 to 2016.

 

Extent
Purpose: The aim of this study is to clarify how a local construction logistics center affects a construction project in an economic perspective as well as a work environment perspective. The study is a comparative study conducted partly on a project that does not use a construction logistics center and partly on a project where a construction logistics center is used.

Delimitation: The study is limited initially to two case studies which are almost identical conditions regarding entrepreneurial, organizational, size, frame systems and geographic location. The study focuses on the project's internal construction logistics at the work site.

Objective: To investigate how a local construction logistics center can affect resource efficiency and sustainable construction.

Schedule:

  • Phase 1 (without construction logistics centers), from August 2013 to December 2014
  • Phase 2 (with construction logistics centers), is expected to run from 2015 to 2016

Working Methodology
In order to arrive at the result, index data is required to start with.  In the process necessary data will be collected using the methods described below.

  • Survey on touch screens: The questions deal with what the construction workers use their time for during the workday, and how they experience working at the construction site. The questionnaire was answered twice a week on touch screens placed in sheds. The survey will take 3-5 minutes to complete and has been positively received by Viktor Hanson's employees, as the process of answering the survey is quick and easy.
  • Interviews: To get more in-depth answers and to find out the causes of arising phenomena interviews is conducted with construction workers working in the project. The interviews is made with 11 people and to gain a broader perspective on the answers respondents have different professional roles. Depending on the profession of the interviewed person, each respondent get to answer questions regarding various areas related to production economics and the environment.
  • Observations: To relate the respondents' answers to questionnaires and interviews with the reality, observations is conducted 1-2 times a week on the construction site. The observation is carried out in a way where the observer is photographing the work site and filling out an observation schedule where judgments are made about inventory management, cleaning and work environment. In this way, direct differences between the projects can be identified.
  • Documents Studies: The fourth and final data collection method consist of collecting documents from the workplace that can help to provide a picture of how the work is structured as well as how and what is being transported to the project. Documents covered is review of waybills, APD plans and schedules.

Results and Reports
During the study, the partial results will be published on ndslogistik.se. The overall assessment of how construction workers experience a change of value creating time, more order and an impact on the working environment at the construction site where a construction logistics center is used will be answered and published in 2016.
