6.2 The Site Engineer shall be responsible for the execution of the Roadway Excavation. 6.3 The Quality Control Engineer shall be responsible for monitoring the working

excavation level as per the approved plans and specifications. He shall likewise ensure that appropriate documentation such as excavation permits, clearances, etc.has been obtained from the concerned authorities prior to the start of the work.

6.4 The Surveyor is responsible for establishing the boundaries, limits and extent of Roadway Excavation.

6.5 The Safety Officer shall ensure that safety of the workers is taken into consideration at all times. He shall make sure that stake/poles and barricades with warning tapes on it shall be in place whenever required as the excavation progresses. Warning lights shall likewise be introduced if found necessary.

7. PROCEDURE:

The foregoing procedure for the Roadway Excavation will serve as a guide by the Site Engineer together with the surveyor along the course of their work in order to achieve an acceptable quality of workmanship and attaining the optimum results with less time and effort:

7.1 GENERAL

The Excavation Works shall be done by the use of the Excavator, Bulldozer, Grader,Dump Truck for soil disposal and a set of minor tools such as shovel, wheel borrow, etc.

7.2 SURVEY LAYOUT

7.2.1 The Surveyor in coordination with the site engineer shall stake out the limits and extent of the excavation and constantly check the depth of excavation and inform the excavator when and where to stop digging.

7.2.2 He shall make sure also that working level is established so as to avoid over cutting. 7.2.3 The Site Engineer will coordinate with the planning department the potential

location of utility services that may be affected if any and this will be marked by the Surveyor.

7.3 SITE CLEARANCE/EXCAVATION PERMIT

7.3.1 Before commencing the roadway excavation, the area will be cleared of all tress, stumps, roots, bushes, vegetation, debris, materials or other obstructions.

7.3.2 Before removal of any trees or shrubs, the approved Environmental Clearances shall be obtained from the competent agency the Meteorology and Environmental

protection Administration (MEPA).

7.3.3 Holes left by slumps or roots shall be filled with suitable material compacted to the Engineer’s satisfaction. The compacted density of the fill will be equal to or greater than 95% of Maximum Dry Density as determined in the project specification.

7.3.4 If there are many structures or any other existing structures such abandoned underground utilities or any other obstruction on the excavated area, the removal work procedure will be submitted separately to obtain the approval from the concerned authority.

7.3.5 The excavation will not proceed unless the municipality permit for excavation has been obtained.

7.4 TRIAL PIT LOCATION

7.4.1 Trial Pit Location Plan shall be submitted for approval by the consultant.

7.5 ROAD WORKS EXCAVATION 7.5.1. Excavation Phasing

The excavator in coordination with the site engineer shall locate and determine the sequence of excavation phasing as well as the entrance and exit of equipment vehicle.

7.5.2. Soil Digging, Cutting, and Grading

a. Digging, Cutting, and grading of soil shall be done to a working level to a depth as shown on working drawings and in constant monitoring with the surveyor and the site engineer.

b. Rock shall be excavated to a depth of 150mm below subgrade within roadbed limits and backfilled as per approved materials compacted to the required density.

c. Soil below subgrade other than solid rock shall be thoroughly scarified to a depth of 150mm throughout this layer and will be brought to a moisture content suitable for maximum compaction output.

d. Removal of unsuitable material (soil) shall go beyond the excavation level (sug-grade level) until excavation reaches a soil of which appropriate load bearing has to be achieved.

e. Careful Excavation shall be observed along the course of the work not to disturb/damage the underneath existing pipe utilities if any.

f. Once the soil is dig, it will be immediately transferred to the standby dump truck.

7.5.3. Stability of Excavations

a. Slopes of excavations to comply with the following: 1. Slopes of cuts in natural; 1:1

2. Slopes of compacted fill; 1-1/2 : 1 3. Slopes of uncompacted fill; 2:1

.

Maintain sides and slopes of excavations in a safe condition until completion of backfilling
