SPECIFICATION FOR EXCAVATION AND EARTHWORK

The Contractor shall be solely responsible for any damages caused to existing work

during the Construction

EXCAVATING

Drawings or other records obtained by the Contractor from relevant Authorities, are

encountered, the Contractor shall notify same to the Engineer. The Contractor shall also

furnish to the Engineer for his approval the Methods of protecting such service lines during

the construction works.

All work in connection with protecting and maintaining the said service lines, cables etc.

shall be to the entire satisfaction of the relevant Authorities concerned. The Contractor

shall be solely responsible for any damages caused to such existing work.

EARTH FILLING

Stripping of Top Soil;

Where the existing ground surface is covered with vegetation top soil or other

unsuitable material, it shall be removed together with roots, rubbish or objectionable

materials etc. Vegetation or other unsuitable material so removed shall be disposed

within 5.0 kms of the site.

Borrow Material

Borrow material shall comply with the following specifications:

a) It shall be tested for its suitability by a recognized testing organization acceptable to

the Engineer. It shall be well graded soil mixture with gravel and sand (not less than

70%) silt and clay (not more than 30%).

b) The Contractor shall forward from each borrow pit at different levels, the test results of

particle size distribution and Proctor compaction tests by a recognized testing

organization to the Engineer for approval.

c) It shall be free of vegetation, roots and such other deleterious material.

d) Maximum dry density at optimum moisture content (Standard Proctor Density) shall

not be less than 1.6 gm/cm3.

e) Maximum size of particles shall not exceed 120 mm.

Placing of Fill Material

The distribution and gradation of the material throughout the fill shall be carried out as

directed by the Engineer, so as to ensure that the fill will be free from lenses, pockets,

streaks, or layers of material differing substantially in texture or gradation from the

of 170

surrounding material. The borrow excavation and placing operation shall be such that the

materials when compacted will blend sufficiently to secure the best practicable degree of

compaction and stability. Successive loads of material shall be dumped and spread so as to

produce the best practicable distribution of material and for this purpose the Engineer may

designate the locations in the fill areas where individual loads shall be deposited.

The fill material shall be placed in layers not exceeding 225-mm thickness in loose state. The

fill shall be compacted at each lift to not less than 90% of the Standard Proctor Density for the

building area. For the earth filling along the road way and access roads, the fill shall be

compacted at each lift to not less than 100% of the standard Proctor density. The thickness of

the 1st layer may be increased to facilitate compaction with the approval of the Engineer.

The method of compaction shall be approved by the Engineer.

Moisture Control

The moisture content of the fill material prior to and during compaction shall be maintained

and distributed uniformly through each layer. The allowable placement moisture content will

be determined by the Contractor on Engineer’s approval so that fill placement can be made

under optimum moisture content of the fill material.

Density Control

To determine the dry density requirements of the compacted fill, field and laboratory tests

shall be made on samples of compacted material taken on a 10-m grid.

Method of Measurement

The quantity of fill material shall be determined by measuring the depth by auguring and

multiplying by the area each auger hole represents. All such quantities shall be added to

determine the total quantity. Interim payments shall be made on quantities estimated by the

Engineer.

General Construction Methods

The Engineer shall have complete control over the excavation, moving, filling and disposition

of all material and shall determine the suitability of material to be placed in fill areas. All

material determined unsuitable shall be placed in spoil area and / or removed from site as

directed by the Engineer.

The Contractor shall inform and satisfy as to the character, quality and distribution of all

materials to be excavated filled, spoiled and borrowed.

Should the Contractor through negligence or other fault excavate or fill beyond the

designated lines, he shall replace/remove such excavation/fill in an approved manner and

conditioned at his own expense.

Any other information which is indicated on the Drawings or Bill of Quantities, which may

be at variance with the above, shall be brought to the notice of the Engineer.

Minimum free fall of concrete should be limited to 1.5 m during the placement of concrete.

In the event Lift height is greater than 1.5 m Trimy pipe or similar arrangement should be

used. In any circumstances, casting of columns together with slab and beams will not be

allowed.

of 170

WORKABILITY

The concrete shall be of such consistency that it can be readily worked into the corners

and angles of the formwork and around reinforcement without segregation of the

materials or bleeding of free water at the surface. On striking the formwork the concrete

shall present a uniform face, free from honey combing, surface crazing or subsequent

excessive dusting.

The Contractor shall carry out a series of workability tests on samples obtained from the

batches of the trial mixes used for the preliminary test cubes. These tests shall be

carried in accordance with BS 1881.

No additives or admixtures ie. Material other than cement, aggregate or water shall be

added to the concrete without the written approval of the Engineer.
