Sharpening going on in the construction industry!  (pdf)

Since 1 January 2002, BKF received special funds, about 20 million per year, to support appropriate pilot projects. These would in various ways shed light on the above issues and thereby point out important ways to bring down the costs of new construction -- primarily housing. All stages of the building process would be challenged and made more effective, without thereby compromising the essential qualities of the end product, the dwelling.
Until 2007, approximately 107 million SEK has been put into some 105 pilot projects, which have resulted in just as many debriefings. In this report, the debriefings is summarized to identify how it should be cheaper without affecting quality.

The purpose of this study is to develop knowledge about collaborative procurement strategies and how these strategies can contribute with motivation for an effective project performance in smaller municipal infrastructure projects. The study also aims to develop an understanding about how a construction logistics centre is applicable to an infrastructure project. Also, how the procurement strategies can create motivation to obtain an effective utilization of a construction logistic centre. To achieve the purpose with the study, a case study of Stockholm Royal Seaport (Norra Djurgårdsstaden) with focus on two infrastructure projects with a mandatory utilization of a construction logistic centre, has been examined. By an abductive method, in terms of literature studies and semi- structured interviews, this study results in that partnering and the payment form cost reimbursement have been a considerable important strategy for the project success.
The main conclusion in this study is that collaborative procurement strategies and its components are applicable to a smaller municipal infrastructure project. Significant components to obtain an effective project performance has also been found. Furthermore, the study has shown that a construction logistics centre, designed as in Stockholm Royal Seaport, is not fully adapted to infrastructure projects with similar conditions as the two studied projects. This makes it difficult to draw general conclusions about how procurement strategies should be formed to create motivations for an effective utilization of a construction logistic centre. However, suggestions are given about how procurement can create motivation to obtain an effective utilization of a construction logistic centre by using literature studies. Conclusions can be drawn that partnering and a focus on long term relationships has created motivations for the actors to work effective.

As a step towards a more environmentally friendly and sustainable Stockholm, a logistics center for coordinated construction logistics (BLC) was established in 2013 at Stockholm Royal Seaport, an urban area, at the initiative of the municipality of Stockholm. Coordinated construction logistics of this size is rare in Sweden and BLC requires mandatory affiliation for every developer and contractor in the area. BLC has caused a need for change in the different stakeholders’ working processes during production in order to fully utilize the logistic center. Being affiliated to and using BLC also implies increased costs for the project. That is the reason why discussions occur regarding which stakeholder should take the financial risk. This could be managed during the procurement. Thereof, the aim of the study has been to look at how the ability to adjust to changes that innovations as BLC requires could increase or decrease by the choice of procurement strategies. The intention is thereby to identify whether or not procurement could be used as a tool for change management. The report is a compilation of a case study of two new production projects with an abductive approach. The study is based on an extensive literature study, observations and interviews of participants of the two projects and can be classified as qualitative, empirical research with a hermeneutic approach to obtained empirics. The study shows that the procurement strategies have been affected by BLC in such way that the developer has made an addition to the technical specifications that is handed out when procuring contractions. The addition contains information about the purpose and the scope of BLC. It also includes recommendations for how BLC could be used in an effective and innovative way. The main contractors then in turn forward the extended technical specifications to the subcontractors. Despite the developer’s vision of an effective and innovative use of BLC, the right incentives for such use have not been created. It has been proven that the difficulty lies in the fact that BLC does not yet function smoothly for its users and that the users doesn’t fully understand how BLC functions and its purpose. The stakeholders also find it difficult to estimate the costs of using BLC, which is why the developer has taken the biggest economic risk regarding BLC in the projects. The general opinion among the contractors is that BLC is redundant and not necessary in the area. The reception and adoption has therefore been problematic and the attitude towards using BLC has been negative. In order to expand the use of BLC and ensure that all stakeholders share the same view about the purpose of and the need for BLC the developer should be more proactive in this matter. An early involvement of the contractors in the procurement phase and jointly defined ways of using BLC in combination with financial incentives could have a thawing effect on the contractors and increase their ability to accept and adopt the changes BLC requires.

 

Examensarbete Logistikplanering hos svenska byggentreprenörer  (pdf)

The construction industry has an inefficient logistics management with an unsatisfied delivery and material flows. In comparison to other industries, the construction industry has more additional work due to rearrangements of materials and higher risk for damaged materials. It is proved that inadequate logistics planning creates a low production rate. Therefore, this master thesis aims to study the Swedish Contractors logistics planning for construction sites during the design phase to provide potential improvements.

Changes are easier to implement at an early stage, therefore the logistics planning should be conducted during the design phase. Today there is no standardized approach to logistics management, therefore a new mindset is required regarding the importance of logistics in the construction industry.

Logistics units are rare at the Swedish Contractors, but an implementation of a small central logistics unit will enhance expertise within the logistic field. The unit can develop a standardized logistic analyze and prepare contracts with third-party logistics companies.
Logistics planning should consist of a standardized logistic analyze, a checklist for the projects to easily get an overview of the required content. The logistic analyze contains of four sections; supply analyze, material analyze, APD-plan and purchasing data. It is also recommended to provide the new construction projects with summarized cases, to base their logistics planning from.

It is easier to find incentives to follow a plan if the planning is carried out by the individuals who will use it. Therefore it is recommended that the logistics planning should be conducted by the construction project manager, the purchaser, the logistics manager and logistics experts. A distinct role description early in the project enhances the work performance, as each project participant is aware of each other’s authorities and responsibilities.

Logistics is a current area of discussion, as investments in logistics can generate benefits such as; more efficient processes, economic profits and satisfied clients. A well conducted logistics planning during the design phase can create a more efficient Supply Chain Management at the site. In addition, the organizational structure can be improved by a standardized approach, which generates a confident amongst the employees. Logistics planning can also generate competitive advantage at the tendering phase and enhance for long-term relationships.

 
 

BLC delavstämning 2011-2016  (pdf)

Construction Consilidation Center (BLC) is located in Ropsten in Stockholm. BLC has been in operation since April 2013, and was inaugurated in May of the same year. Since its inception in 2013, many services developed on the BLC, the plant has been expanded and the organization has changed. BLC is a development project and is in constant change. This document summarizes Fredrik Bergman BLC how the project evolved from a decision in 2010 on a logistics center, to now have a fully functioning business in constant change.

This report is intended to be a partial citation for the period January 2011 to June 2016. The report shows how development / innovation work on the construction of BLC have been implemented within the Royal Seaport. The report also shows the goals and intentions of the City of Stockholm, the business model, calculations and dimensioning have been completed, the plant developed and how various innovations on both technology and management have been implemented. The report also describes the ongoing research and development projects and completed theses connected to the BLC.

 

Att minska byggavfallet  (pdf)

The construction waste can be reduced. In this report we describe how it can be done. The goal is to lay the groundwork for the prevention of waste to be a matter of course in construction projects in the same way as recycling is already.

This method is the result of a cooperation project between Tyréns AB, NKS building within Stockholm County Council and Skanska Healthcare. The purpose of the project was to develop methods for preventing construction waste in new production. The project was funded by Sven Tyrén Foundation, Stockholm County Council and Skanska Healthcare. The building of Nya Karolinska Solna has served as the starting point for the project
