SAFETY, HEALTH AND ENVIRONMENTAL INFORMATION

In addition to the hazards/risks normally associated with the types of work detailed on this drawing, note the following :

CONSTRUCTION:1. Work within, and adjacent to, the Highway. Appropriate traffic management for all work carried outwithin or adjacent to the live highway.2. Deep excavations and work in confined spaces during the installation and modification of drainagesystems.3. Existing utility diversions will be required. Some utility routes are of strategic network importance4. Mitigate impact damage and undemining of structures/foundation(eg Network Rail structures).5. The Contractor will be responsible for managing all earthworks operations(inclusiveaccess/egress/level variations/removal of obstructions plus potential for contam & ordnance).6.Tree felling to be undertaken by suitably qualified tree surgeon.7. Deep excavations and the use of appropriate trench shoring.8. Work within and adjacent the river channels.9. The 1800mm TW sewer is understood to be generally at 3/4 bore.10. The Contractor shall be aware of the high volume of vehicular and pedestrian movement withinthe site.

MAINTENANCE / CLEANING:1. Deep excavations and work in confined spaces during the maintenance and modification ofdrainage systems.2. Maintenance within the highway will require appropriate traffic management.3. Bridge inspections and maintenance shall be cognisant of the hazards associated with workingclose to water.

DECOMMISSIONING / DEMOLITION:1. Deep excavations and work in confined spaces during the removal of drainage systems.2. Structural stability of existing structures.3. Inundation of excavations from the Ravensbourne and Quaggy

It is assumed that all works will be carried out by a competent contractor working, where appropriate, to an approvedmethod statement

NOTES

1. All dimensions are in metres unless noted otherwise.

2. No frost susceptible fill material to be used within 450mm of the finished surface level.

3. Skid resistant surfacing refer to drawing 20486/063/700/104.

4. For pavement depths refer to Appendix 7/1 of the Apendices to the specification.

5. Red tactile paving required at controlled crossings, Buff tactile paving required at

Uncontrolled crossings.

6. Where new kerbing is proposed adjacent to existing carriagway, the contractor shall allow

for a 300mm surface course carriageway patch in front of new kerb.

7. Refer to 20486/063/1200 series dwgs. for red bus lane areas, cycle routes and high friction

surfacing.

8. Contractor shall allow for full depth expansion and contraction joints within all footway

surfacing for types incorporating a C32-C40 URC roadbase.

9. Pavement foundation thickness assumes 3% CBR. Contractor to verify and provide

information to the Designer 7 days prior to sub-formation excavation.

10. All pavement layers are to be tied in to existing or new pavements with 150mm steps per

bituminuous layer.
