METHOD STATEMENT FOR EARTHWORK CUTTING AND FILLING

The objective of this approach of declaration is to specify the procedures to make certain that the recommended products as well as handiwork to be used at the site are adhering to the problem/ needs as specified in the requirements.


This method statement covers the needs for all earth works excavation up to and also consisting of the prep work of development level. This technique declaration is to be taken on during earthwork activities for widening and strengthening of freeways. This method declaration describes the regulating aspects throughout the exaction of earthworks.3.0.

SAFETY AND SECURITY, HEALTH AND WELLNESS AND ALSO ENVIRONMENTAL CONCERNS.

v Problems as well as precautions noted in the task specifications shall be followed as minimum.

v All personnel involved in the project shall be inducted on the safety, health and wellness and environmental problems related to the work.

v Just educated employees with relevant experience will be allowed to handle equipment.

v Appropriate Safety and security Signboards, obstacles and illumination and also various other safeguards will be provided as required by the nature of as well as area of the works. All operations shall be performed according to the safety and security needs.

v All area employees will use PPE safety and security needs like safety and security footwear, headgears, cover all, dust mask, and so on advertisement called for.

v METHODOLOGYA.

LAYING OUT:.
Prior to any start of any type of physical works, a specialist surveyor will be selected to carryout demarcation works and develop bench marks on website. Upon obtaining all the needed survey information, a joint study to examine existing ground levels will be performed with the consulting engineers'.
PREP WORK OF SITE:.
When any kind of material is gotten rid of outside the site, the disposed product shall be graded to a cool look and will not block natural drainage or create damage to highways or residential or commercial property. All preventative measures will be required to protect against any disintegration of the dirt on the impacted locations.
All unsuitable product as well as excess ideal product will be run to ruin in suggestions authorized by the Designer.
EXCAVATION OF CUTTINGS.
The excavation of cutting shall be carried out based on the pertinent approved illustrations as well as to the degrees, widths and also heights shown thereon.
Hauling of material from cuttings or the importation of fill material to the embankment or various other locations of fill will proceed only when enough compaction plant is running at the location of deposition to guarantee conformity with the specification demands.
Any kind of excess deepness dug deep into listed below the formation level going beyond tolerance of 300mm will be made good by backfilling with appropriate product of similar attribute of that gotten rid of and compressed according to specs.
EXCAVATION FOR WEBSITE LEVELLING AND ALSO DIRT REPLACEMENT.
Finish degree shall be videotaped in accordance to survey technique as well as jointly checked in the visibility of Engineer.
The side inclines of cuttings as well as embankments will be based on the authorized drawings

EXCAVATION GENERAL.

Elimination of Inappropriate Material as well as Soft Spots.
If during the progress of the job the dirt encountered has characteristics, as determined by examinations performed under the direction of the Designer, that make it inappropriate for unification in the roadway embankment, the Specialist shall dig deep into and also eliminate such improper material to the level directed by the Engineer.

Where Service provider discovers separated soft spots during excavation, this product will be eliminated to the extent routed by the Designer.

No dug deep into suitable material will be removed from the website without the authorization of the Engineer. Should the Service provider allowed to get rid of ideal material to suit his operational procedure after that he will make great any ensuing deficit of fill product developing there from.

Where the excavation discloses a combination of suitable and also unsuitable product the excavation shall, unless otherwise agreed with the Engineer, will be accomplished in such manner that the appropriate products area excavated separately for usage in the works without contamination by the improper material.

The transporting of dug deep into product to areas of fill will proceed only when adequate spreading and compacting plant/equipment are operating at the location of deposition to make certain placing as well as compaction.

Improper excavated product shall be gotten rid of and carted away to an authorized area after approved by the Engineer.

DIGGING DEEP INTO HIGH DEGREE LOCATIONS.

The Professional shall excavate high level areas in all materials consisting of rock for the full width of the roadway construction to the top of the called for below grade.

ROCK EXCAVATION.

Excavation in rock may be carried out by a tracked excavator and ripper or by the use blowing up with explosives or any other approach accepted by the Designer.
After it has actually been developed that the excavated material is rock and also after the area where such rock exists has been defined, the Specialist shall incorporate the rock in the embankment.
EXCAVATION FOR PITS AND TRENCHES.
All trenches and pits under roadways shall, where feasible, be dug deep into, backfilled and also compressed before road building commences.
The sides of the excavation shall be properly supported whatsoever times.
Trenches as well as pits shall be kept devoid of water.
Trenches for pipelines or ducts shall be dug deep into to the degrees and slopes indicated in the contract papers.
LOADING GENERAL.
Filling low-level areas shall be to the level of below quality as assigned. After conclusion of clearing up and also grubbing, the Professional shall carry out the essential progressing in order to control the density of the layers of fill.
The existing natural ground will be scarified in place to a minimal deepness of 75mm for the full size of the embankment. The scarified product will be leveled and also compacted to a minimum of 95% optimum dry thickness.
Where an existing embankment is being broadened, the existing embankment slope shall be cut and compressed into benches of minimal width 1m and depth 500mm before placing as well as condensing each layer of brand-new embankment material unless or else routed by the Designer to suit particular circumstances.
The Service provider will not proceed with filling as well as compaction any kind of subsequent layer before screening and securing the approval of the Designer for the previous layer.
Each fill thickness shall not surpass 250mm.
FORMING OF EMBANKMENTS AND ALSO OTHER AREAS OF FILL.
In locations of shallow filling, where after the removal of top dirt, before embankment building and construction is compacted, the appeared of the ground shall be graded as well as compacted.
Embankments and also various other areas of fill will be developed of suitable material.
All earthworks product placed in or below embankments, listed below development level in cuttings or elsewhere in the works will be transferred and compacted as quickly as possible after excavation in layers of density not exceeding 250mm.
Embankments will be built up uniformly over the full width unless otherwise shown and also will be kept whatsoever times with a sufficient camber and also a surface area adequately even to allow surface area water to drain conveniently from them. Throughout the building of embankments, building traffic or water disintegration shall be made good.
Compaction of embankments as well as other locations of fill shall be undertaken to the demands of requirements. The embankments will be constructed to enough width to allow adequate compaction at the edges prior to trimming.

PLACEMENT & COMPACTION OF EMBANKMENTS & OTHER FILLS UP.

Planet fill on the embankments will be spread so as to produce consistent distribution and gradation of the earth fill throughout.
Collection of rock excavation, which would certainly interfere with appropriate compaction, will not be allowed. The planet fill shall be placed in constant, approximately straight layers over the length being created for the full width of the embankment.
Product which has been compacted to a completely dry density less than called for or at a wetness web content outside the bearable variety shall be removed or revamped and re-compacted until the required properties are accomplished.
