The expansion of the district heating network in Egedal is a comprehensive and ambitious project aimed at converting heat consumers from oil and natural gas to district heating. This will significantly contribute to making the energy supply in Egedal Municipality more environmentally friendly. The expansion includes the installation of over 95 km of main and distribution pipes, ranging from DN32 to DN250, as well as the connection of over 5,000 customers and the establishment of more than 100 km of service lines.
This project is a crucial step toward ensuring a sustainable energy supply for the residents of the area. It will improve energy efficiency and significantly reduce CO2 emissions, in line with Egedal Municipality’s environmental goals.
The project will take place over seven years, from 2022 to 2029, reflecting the scale and complexity of the work involved. The extended timeframe ensures that all phases, from planning and design to installation and commissioning, can be executed with the necessary care and precision.
Technical Consultancy
Norsyn has played a central role in the project by conducting preliminary studies and preparing the overall master plan and budget for the expansion, including the routing and sizing of the pipe network.
Additionally, we have handled the complete detailed design and overall project management during execution. Together with Egedal District Heating, we have invested significant resources in devising new and smarter methods for establishing district heating, focusing on optimizing both costs and time in the project. In this context, Norsyn has developed a new laying method, utilizing foam pads in areas where they were previously not used, significantly reducing the number of sound impacts and weld holes without compromising the requirements of EN13941.
Furthermore, the client has opted to detail design all main and distribution pipes with length profiles, which has provided great value during the subsequent execution phase, where the length profiles have been an important tool for planning trench depths and identifying and managing obstacles in the route.
In addition to detailed design, we at Norsyn have also performed construction management and supervision during execution. This service has included monitoring the construction process to ensure that the work was carried out in accordance with project specifications and schedules. We have conducted regular site inspections, coordinated between contractors and the client, and ensured that any challenges were addressed effectively and professionally. This meticulous management and supervision have been critical to the project’s success and quality.
Tendering and Collaboration
The works have been tendered in three separate framework agreements, some of which are strategic collaboration agreements with a cost+ payment model. This approach aims to involve contractors early in the planning of the work (early contractor involvement) and to promote collaboration among the parties in the project (client, consultant, and contractor).
At Norsyn, we have been responsible for preparing the tender materials based on AB18 (a contract used in Denmark for construction projects that outlines the rights and obligations of the involved parties), supplemented with detailed descriptions for earthworks, welding work, and pipe supply. This material has ensured a high level of detail and quality throughout all phases of the project.
Customer Installations
As part of the project, we have also handled the tendering of a framework agreement for the supply and installation of district heating units. This framework agreement includes installations in residential segments and larger customers with a heating demand of up to 250 kW. The works and supplies have been tendered as a single framework agreement, ensuring a consistent and efficient process from planning to installation.
Implementation of Pre-insulated Plastic Pipes
Several phases have been executed using pre-insulated plastic pipes instead of steel pipes. This has led to a significant reduction in both time and costs in the projects, pushing the industry towards necessary reductions in construction costs to continue realizing more district heating projects across the country, contributing to the ongoing efforts to phase out fossil fuels for heating.
