22、g to the approved traffic diversion plan as and when required. The work area will be barricaded with barricading board and construction signs will be displayed at the site. Lighting with adequate intensity will be provided in and around the work area during the night shift. Area will be cleared of a

23、ll large bushes, trees, hedges and tree roots within a distance of 5.0m from the edge of the line of utility.6.3 Preparation (to be done in consultation with a competent person) Study the soil characteristics with reference to angle of repose for soil required etc. See that excavated area is not blo

24、cking the access to the site for man and material both or otherwise necessary sign shall be displayed at appropriate locations. It should be ensured that there is no exposed live wire in working areas which are accessible to building workers other than those authorized to work on such live lines. Al

25、ternate route for traffic should be provided (in case of road blockage). Ensure Road block procedures are followed. Ensure that there are no vibrations from an external source which may impact the excavation. Ensure that consideration has been given to proximity of adjacent structures while finalizi

26、ng the method of excavation. All efforts will be made to locate underground utilities that may reasonably be expected to be encountered during excavation work. A cable detector may be used before start of excavation. In the situation where a cable or utility is found to be existent, the engineer wil

27、l judiciously after obtaining the excavation clearance, excavate a trial trench manually only. The depth of trial trench shall not exceed 1.5 meters in general, 2.0 meters in special cases so as to ascertain the presence of any cable/gas pipeline/other utility. In case, no cable or other utility ser

28、vice lines detected in the trial trench, mechanical excavation upto 1.2 meters depth shall be undertaken. The whole process is repeated for the next 1.2 meters. Supervision, workforce and Inspection It should be ensured that all excavations are supervised by qualified person. Give Tool Box Talks reg

29、arding safety measures to be observed to the workers involved before starting the job. Confirm methodology to be adopted, explains Risk Assessment and plan of action in case of emergency. Confirm PPEs provided, are as per the work permit. If the depth of excavation is more than 7 feet (2.2 meters),

30、then double lifeline full body harness must be used. The harness to should be secured to a suitable lifeline. Minimum person shall be kept inside pit. All idle workers should be removed from there. Each excavation shall be inspected daily by the qualified persons, after heavy rains & Storms, or more

31、 often if conditions change rapidly. 6.4 Marking of pier locations:Marking of pier location and pile cap prior to work shall be made. Once the alignment of the project is fixed, the pier locations will be marked precisely using a total station. Then at each location, excavation layout for trial pit

32、corresponding to the pier will be marked with paint/peg system on the ground.Extreme precaution will be taken while excavating the area where any cable or pipe is identified6.5. Utility identification by detector.At first metal and cable detector shall be used for identification of existing Utility

33、if any. A trial trench shall be excavated manually only after clearance from competent Electrical personnel in respect of Electrical cables subsequent to testing by a cable detector 6.6 Excavation at Ground level/ Road level:Excavation shall be done manually by making trenches diagonally to pile cap

34、 to a depth around 2.0m. Excavated earth shall be stored 1m away from the size of the pile cap/pier location. Utilities passing within the pile cap/ pier layout can be located by manual excavation. The crust of the existing road shall be excavated using jack hammer, driven by diesel operated air com

35、pressor. Extra care shall be taken while excavating near the utility location.6.7 Excavation below ground level:Once the existing road has been excavated the remaining depth of trial pit shall be excavated using shovels, pickaxe and spades. If the soil is of sliding nature suitable slope/benching wi

36、ll be provided. The trial at pit first shall be excavated up to a depth of 1.2m.Extra care like shoring (detailed procedure mentioned below), battering or other means to support the pit shall be taken while removing the soil near the utilities after excavating to a depth of 2.0 m, the trail pit will

37、 be again checked manually for pipes/cables. If utility is identified then the pit will be excavated to required depth manually. If not, the trail pit will be terminated at 2.0m depth. The utilities found in the trial pit shall be protected by steel boards or other suitable means as per the utility

38、authority. In case of accidental damage to the utility, it should be immediately informed to the concern authorities of utility and client.6.8 Shoring Bracing or shoring of trenches shall be carried along with the excavations. Trenches 6.56 feet (2 meters) or deeper must be shored or sloped back to

39、the angle of repose. Any excavation in unstable ground will require shoring or sloping. An adequate supply of materials such as timbers, trench sheets & props with which to shore the sites of excavation must be delivered to the site before starting excavation. Material used for sheeting, shoring or

40、bracing must be of good condition. Timbers must be sound, free of large knots and of appropriate dimensions. Shoring with GI sheets shall be firmly supported by steel/ scaffold pipes with spacing of 4 ft in horizontal & vertical direction with cross bracing & shall be suitable clamped. Supporting sy

41、stems; i.e., piling, cribbing, shoring, etc., shall be designed to meet accepted engineering requirements. When tie rods are used to restrain the top of sheeting or other retaining systems, the rods shall be securely anchored well back of the angle of repose. 6.9 Recording of utilities in trail pit:

42、Once the excavation is completed, all the utilities shall be recorded in respect of the direction of the passing and its depth from road level/ground level in coordination with client representatives. A layout drawing of utilities present in the location shall be prepared with coordinates for each l

43、ocation and signed by both Contractor and Client representative for future reference. The concern authorities of respective utilities shall also be informed for further action.6.10 Backfilling of Trail pit:Once all the utilities are identified the trial pit shall be backfilled with same excavated ma

44、terial and compacted. 7.0 RECORDSAfter identification of all utilities, detailed signed sketch with coordinates shall be submitted to DMRC with photographs.8.0 SAFETY, HEALTH AND ENVIRONMENT: Working area shall be barricaded and display boards shall be provided Sufficient Lighting shall be provided

45、in the working zone Safety stewards shall be engaged for monitoring to avoid unsafe conditions and unsafe acts All the staff and workmen shall be provided with personal protective equipment like safety helmets, safety hand gloves, safety shoes, safety goggles, retro reflective jackets etc. All the p

46、ersons involved shall be given the task briefing before start of the excavation activity. First aid box with medicines shall be made available at the site office No stranger shall be allowed in the vicinity of the working area.9.0 EMERGENCY PROCEDURE FOR ACCIDENTAL DAMAGE TO GAS PIPELINE, PETROLEUM

47、PIPELINE OR ANY OTHER CRITICAL UTILITY Dial Before Dig Always make sure that there are no gas / water /chemical pipelines etc. underground the area where planning to dig. Digging or running heavy equipment can damage underground lines. Even minor excavations can damage gas pipelines and can cause fi

48、re. Dial the concerned utility emergency number for confirmation and clearance. Emergency Procedure in case of accidental damage Cordon off and evacuate the area to a safe place. Call the utility emergency number (Gas, Electricity, water etc.) and then notify local emergency services (Fire etc.). Fo

49、r example, call IGL emergency no. for any damage to gas pipeline. Stay upwind of any suspected leak. DO NOT operate machines, mobile phones, or any electrical items that may generate spark in the area. Prohibit smoking in the area Keep people and traffic away from the accidental damage area PROHIBIT
