Building Information Modeling/ Virtual Design & Construction
The housing area on Betesgatan in Borlänge was built during the million homes program in the 1960s and is now getting a major makeover. Skanska is taking a comprehensive approach and renovating everything from main plumbing lines to courtyards and garage buildings.
The 55 apartments are being renovated and the four-story building is gaining an additional floor, which means that more people will have an opportunity of moving into this desirable area. Work continues and we anticipate being ready sometime during 2013-2014.
Skanska has generated an enormous knowledge bank that we refer to as Miljonhemmet. In it, we have collected our experiences from the million homes program. It is from that resource we are retrieving the necessary tools for each project.
For the Betesgatan project we have, for example, utilized a tool to assist us in concrete inspections when developing action plans and conducting balcony renovations.
We also work on solutions that result in lower energy consumption. Thanks to a new ventilation system, window replacements and additional insulation, we lowered energy consumption from approximately 155 kWh per m2annually to 91 kWh. The environment, the building owner and the tenants all benefit from that.
The environment surrounding the buildings is another important part of the project. We are renovating the courtyards and playgrounds so that they harmonize with the park-like walking path that was already in place.
Accessibility is another aspect that we are working on. Together with representatives from the municipal disability council we have inspected the buildings, resulting in greater accessibility for people in wheelchairs or who are vision-impaired.
Security for the residents should be the best possible. Early on in the project we held meetings with the tenants’ association, police, landlords and contractors.
Marknadssegment: Apartment buildings
The renovation of Betesgatan will result in lower energy consumption thanks to a new ventilation system, window replacements and additional insulation. We will be lowering energy consumption from approximately 155 kWh per m2annually to 91 kWh.
The carbon dioxide load per unit generated from concrete is very low since this project involves a renovation; we have an existing structure that is being used for the renovation of the apartments.
All construction materials are evaluated with the help of the BASTA environmental database. This allows us to check whether gypsum board is a good environmental choice or if we should look for alternatives.
It is our hope that the renovation of the living environments both inside and out will result in residents looking after their area. People from different cultures and of all ages can interact in the pleasant surroundings between the buildings. The public benefit generated is increased responsibility for the immediate environment and greater tolerance and understanding among individuals.
A lively environment between the buildings will mean increased security and safety for the residents. Less vandalism will result in lower costs. That will also help make residents feel safe and proud of their area.
This project is a partnership collaboration, which means that everyone is taking more responsibility and is communicating closely with the client. At the start of the project we worked hard to clarify responsibilities and get everyone to see and think about the big picture. That has resulted in smooth cooperation.
Another reason that the project is working well is that our client, Tunabyggen, has hired a project coordinator to handle day-to-day questions. She serves as a link between residents, contractors and the client’s technical and operational organization. Questions both large and small are dealt with and the residents feel secure as they get quick responses.
The buildings on Betesgatan need to be thoroughly renovated, just like most of the housing areas in the million homes program. We are renovating surface finishes in the apartments, replacing windows and adding additional insulation. Other aspects of the project include renovation of main plumbing lines and wet areas, new stairways and the installation of elevators.
Every building is gaining an additional floor. We are using existing pathways for new service lines resulting in Tunabyggen getting new apartments at a much lower cost than if they had constructed an entirely new building.
We are working actively to adapt the buildings to ensure accessibility and have received assistance from the municipal disability council. Wheelchair-bound and vision-impaired individuals have toured the spaces and tested accessibility, including things such as the height of thresholds, easily accessible switches and the width of door openings.
“One thing we learned from Betesgatan is how to display house numbers. Initially, we placed white numbers on glass. For the vision-impaired person who was here and inspected, they were a blurry haze. She suggested a contrasting color around the edge of the numbers. This is a detail that makes a big difference in everyday life, and one that we are passing that on to other projects,” explains Johan Karlsson, a project engineer at Skanska.
Thanks to a new ventilation system, Tunabyggen will be realizing major energy savings over the long term. We are switching from a mechanical exhaust system to an FTX system, which includes exhaust and supply air ventilation with heat recovery. Replacement windows and additional insulation are also contributing to lower energy usage.
At the start of the project we held meetings with the tenants’ association, police, landlords and contractors. One idea that will contribute to a more secure living environment is to tear down the rows of old garages and face new ones towards the housing units, allowing residents a view of their own cars, which will minimize vandalism.
Discussions during these meetings have also impacted the renovation of the laundry rooms. The booking system that is being installed will allow only the person that is doing laundry access to the laundry room.
A sense of well-being is also important. We have rebuilt the courtyards and adapted them to the adjacent park area. The playgrounds have turned out very nice, and the garbage buildings have received nice sedum roofs.
In conjunction with surveying the status of the balconies, we used a concrete inventory tool from Miljonhemmet. We also consulted with a design engineer regarding those damages that we were unable to evaluate ourselves. That work resulted in our developing an action plan for the balconies in conjunction with a supplier of concrete repair products.
“The Betesgatan project is a successful example of how, working closely with a contractor, it is possible to create additional apartments while simultaneously renovating the existing stock, and in so doing improve accessibility to modern standards. The project as a whole, including both building and landscaping projects, will give a boost to the entire Bullermyren area and create a safe and pleasant area.”
