3D Target Depth Design for District Heating


Target Depth Design is a process developed by 3D Technical Design Ltd which aids in the reduction of technical and commercial risks associated with the installation of buried district heating network (DHN) pipework routes, particularly in areas where the DHN must be installed alongside a high density of existing buried services such as within city centre roads and pavements. Due to the potential of district heating networks for decarbonising heat, the number and size of networks in the UK is expected to grow, which in turn increases the demand for accurate and cost-effective designs for these networks.
Installation of new, large size utilities in city centre roads and pavements carries the risk of encountering other existing buried services which may cause significant design changes in cases where their position was not previously confirmed until trench excavation has already commenced. Furthermore, as installation of utilities is often an inherently disruptive process to the surrounding area due to required road closures, last-minute modifications to the design once the excavation and construction have already begun further increase the impact on the local area. As such, the provision of accurate design information to DHN installation contractors plays an important role in efficient construction of the network by minimising design changes, which reduces construction delivery times and lessens disruption caused with open excavations for the local businesses and community. By de-risking the construction phase of the project through improving the design process it is possible to achieve a cost saving for the client and also an increase in productivity and profitability for the contractor.
