Shawfair District Heating Network – Secondary Pipework Design and Installation
Descriptions
Shawfair is a new mixed use residential and commercial development in Midlothian, Scotland. A local Energy from waste plant (EfW) has been identified as the primary source of heat for a district heat network to serve the development area., This project aims to connect the primary District Heating Network (DHN) to an energy centre, which will then supply heat from the EfW to local heat substations or connection points to residential and potentially commercial development sites in and around the Shawfair area. The design and build works relating to the primary DHN and the energy centre are being procured under a separate contract notice., The heat is to be transported via a polymer based pipe from points of connection (valve set at the boundary of the development plot, or heat substation) to an estimated 2900 properties (proposed Shawfair Town development). The development is at present anticipated to be split into 10 to 15 separate development areas, each of which may contain a number of discrete plots. The project is new build., MEL's intention is to appoint a single contractor under the Contract. However MEL reserves the right to appoint more than one contractor., It is anticipated that the scope for each call off under the Contract will be instructed on a site by site basis and will include (but is not limited to) design and build of the polymer based pipe secondary DHN from a point of connection at the boundary of the development area up to and potentially within each building, including:, -Design (RIBA 2 – RIBA 6 requirements) and CDM compliance (Contractor and Designer roles)., -Supply and installation of polymer based pre-insulated pipe DHN within preformed trenches., -Supply and installation of risers within property to the heat interface unit (HIU)., -Supply and installation of Automated Meter Reading (AMR) system field devices as specified by MEL (responsibility for procurement of field devices will be confirmed within the negotiation procedure)., -Pressure testing and commissioning including flushing, first fill, and balancing., -Provision of all manuals, certification and training compliant with practical completion, Operations and Maintenance Manual and Health and Safety file., The scope may also include the installation & supply of risers and laterals, HIU and Heat Meter (MID004 class 2 compliant)., All works shall comply with the technical specification issued by MEL, original equipment manufacturer (OEM) installation requirements, statutory requirements and good industry practice., The Contract will contain options for MEL to instruct the successful contractor to price and carry out the design and build of secondary network extensions to new customers in or around the Shawfair area beyond the initial scope listed., MEL reserves the right to benchmark the price of any additional works under a separate contract notice and potentially award those works to others.
