The site is located off Ellison Fold Way, and this study includes the land within the red line boundary. Figure 1.1 – Aerial view of existing site UCML has been commissioned to provide a desktop utility study defining potential cost and timescale risks that could impact on the overall delivery of the project. The principal aim of this utility study is to identify the key constraints derived from statutory utility infrastructure on the proposed development. 6 | Page UCML | Level 2 Utility Study Ellison Fold Way, Darwen This desktop study has been produced using the statutory records received from each relevant body. UCML is not responsible for the accuracy or quality of this information and has attempted to use reasonable skill and care in investigating the existing site services. Unless stated otherwise, UCML has not made any provision for private networks, unrecorded networks, Liquid Petroleum Gas (LPG) networks, street lighting, CCTV, traffic signals / illuminated signage, data centre networks or drainage/sewerage networks. Figure 1.2 – Site Layout Plan The land shown within a separate red line boundary off Tower View is not included within this study. 7 | Page UCML | Level 2 Utility Study Ellison Fold Way, Darwen All information on the drawings contained within this utility study and elsewhere is indicative only. Verification of the details given on plans shall be undertaken by; The use of plant location equipment to trace all underground plant, and use of hand dug trial holes to confirm the precise location of plant The use of suitable paint or markers on the surface to clearly indicate the position of buried apparatus All works are to be in accordance and compliance with the Construction Design and Management 2015 Regulations, Health & Safety Guidelines and agreed working practices of the relevant utility companies All mains, service cables and pipes should be assumed live until proven dead prior to the commencement of any excavation, demolition or groundworks 8 | Page UCML | Level 2 Utility Study Ellison Fold Way, Darwen 2.0 Scope and Objectives Utilities Connections Management Limited (UCML) is an independent Utility Consultancy providing services relating to the provision of utility connections to all developments. This desktop utility study aims to provide a ‘snapshot’ in time of the current network and recommend budget estimate costs that may be attributed to the connection, diversion, and disconnection of the above described infrastructure. This is based on the information currently available
