All existing services to be located prior to commencement of any work. Any discrepancy is to be notified to the engineers for inclusion on design drawings.  \n2. The contractor is to protect all new and existing services during the course of the works.  \n3. No work to be carried out on existing services and utilities without proper approval from the owner, local authorities or service  \nprovider. All method statements, outages, downtime for works to or connections to existing services to be agreed with the operator.  \n4. All drainage pipelines to be laid as to provide 1 .20m minimum cover under paved surfaces and 0.9m minimum cover under grassed/ soft landscaped areas. Where cover cannot be achieved, drainage pipeline shall be surrounded in 150mm C16/20 DMax20 concrete.  \n10. Manholes:  \n- The invert level given for each manhole is the invert level at the outlet from the manhole. Existing manholes cover/ service cover levels are to be adjusted to suit proposed levels. All metal components within electrical manholes to be earthed in accordance with electrical engineers drawings.  \n- All foul manholes are to be provided with round ductile iron covers. All covers are to EN 124: 1994. Where a manhole / chamber occurs within an area of concrete block paviors, the access cover will be recessed & infilled with concrete block paviors, to match adjacent paving. All manhole covers to be class D400 to EN124 irrespective of location.  \n- Fall across all drainage manholes to be 10mm.  \n11. All proposed services shall be provided with marker plates or acceptable location and identification to be agreed with construction manager.  \n12. Proprietary AJ's and IC's to be surrounded with 150mm concrete C16/20 Dmax20 and fitted with covers to suit traffic loading.  \nFootpaths C250, all other areas D400 .  \n13. All below ground concrete to be class XA1 in accordance with EN 206.  \n14. Anti corrosion tape to be provided around all buried flanges.  \n15. Drainage to be in accordance with the Greater Dublin Regional Code of Practice.  \n16. Last manhole types shall be in accordance with the Greater Dublin Code of Practice for Drainage Works  \nNOTES:  \n1.
