Excavation combined with loading of soil can be effectively carried out by laborers up to a loading height of about 1.00 e.g. into wheel borrow or head baskets.

Above that height, it is preferable to have a separate group of leaders whose output must be matched with that of the excavators.

Necessary output for the Loading ActivitySoil Type Loading Height Productivity cu.m./man-daya.) Loose 0.1 m. 12 – 15b.) Loose 1 – 2 m. 7 – 10c.) Loose Over 2 m. 4 – 5

Excavation, culvert bad and Backfill4.) Building of headwalls with masonry blocks 10 man-days/2 head walls

If the length of the culvert exceeds 6 meters, the number of man-days has to be increased accordingly.

Culvert laying – this task consist of the excavation of the trench preparing the bed, laying o culvert, backfilling and compaction. Number of man-days required varies with the volume of the excavation and the soil type.

VOLUME OF TRENCH CU.M.

Soil Type 7 7 – 8 10 -13

In these cases, the work split over two or more days. First the trench should be excavated and then the preparation of the bed, the laying, backfilling and compaction is done. Therefore the volume of the excavation to be limited following rates and then applicable:Soil Type Productivitya.) Hard Soil 3.50 cu.m./man-dayb.) Very hard, stony 2.00 cu.m./man-day

After completion of the trench approximately 4 man – days are needed to lay 6 rings, backfill and compact to finish road level.

MAINTENANCE BY CONTRACT (MBC)METHODS OF CONSTRUCTION

1. PATCHING POTHOLES – should be done to the areas specified by the contracts and plans duly approved by the Engineer Materials to be used must be suitable to acquire best result when compacted. SCHEDULE OF WORKS: MONTHLY

2. RESHAPING - should also be done to areas required in the plan and contracts. All works should conform to what will be described in the specification. SCHEDULE OF WORKS: QUARTERLY

3. VEGETATION CONTROL AND CLEANING DITCHES – All objects subject for the obstruction of the designed areas should be removed and cleared. SCHEDULE OF WORK: TWICE A YEAR

4. REGRAVELLING - All materials shall consist of hard, durable particles or fine divided mineral matter that can be compacted reaching for stable sub-base. Using especially equipped vehicles materials should be distributed in a continuous uniform layer. The uniform thickness of sub-base materials shall be adjusted prior to the compaction by watering or by drying as required in order to obtain the required compaction. Compaction shall continue until a field density of at least 100 (%) percent of the maximum dry density. SCHEDULE OF WORKS – ANNUALAL

5. BLADING/GRADING – All unstable materials should be removed in areas subject for blading/grading. These areas should be brought to a grade required in the plan and contracts. Compaction will follow using heavier compacting units until required density can be attained.
