This Essay is

a Student's Work

Lady Using Tablet

This essay has been submitted by a student. This is not an example of the work written by our professional essay writers.

Examples of our work

Excavation

The project includes excavation of land in order to construct foundation, refer annex-1A. We will use small JCB precision excavator for the purpose as the area to be excavated is small viz.-less than 200 cubic meter- 6x6x5.25 ,as we have to leave at least 1.5 m space around the form work in order for form work to be erected.

Transportation

The excavated material will be simultaneously loaded in to 25 T Dump Truck hired for the purpose in order to save time and money, which will dump the excavated material into a stock pile 100m from the construction site.

Vehicular access to the stock pile has been secured.

Shoring-

Proper shoring of excavated trench will be carried out. Excavated trench will be secured using trench sheets, M11 interlocking piles in order to avoid falling of earth/collapsing of trench in order to both avoid injury, as envisaged in risk assessment-Annex-3A, and obstruction in work as well.

As per industry standards as the depth is more than 1.5-refer Project Plan

Pile hammer and the braces shall be used for the purpose.

2.2.3 Stage 3-(day8-day11) leveling the bottom surface, fixing of steel /reinforcement

The work required after the erection of the formwork will be carried, during normal working hours, between 7.00 am and 5.00 pm on weekdays .

The work will consist of :-

Leveling the bottom surface

We will pour C-10 concrete of 225mm thickness in order to provide a level weight bearing surface for the structure, just below the 5000mm mark. We will use water level to ensure that the bottom surface is perfectly horizontal.

Fabrication of steel reinforcement on the ground and lowering this into the position with the help of crane and positioning it precisely in position.

2.2.4 Stage 4-(day12-day15) Assembling and erection of formwork and place ment of bolts and RSA-pouring of concrete

Assembly/fabrication of form work using 1000mmx1000mm steel plates hired for the purpose with the help of nuts, bolts on the ground and lowering this in to the trench for securing it in the marked place with the help of crane. Braces will be used to fasten them together in the shape of cube for extra support.

We will use measuring tape and plumb lines to make sure that it fits in place and is perfect square conforming to the measurement viz. 4500mmx4500mm.

We will use supports to make sure it is perfectly in place and shape.

Assembling the fixture for securing Bolts in precise position as margin of only 2mm is available and putting it in place with the help of adjustable support rods that come with the fixture.

Placing of RSA in position

4 RSAs each perfectly at corner shall be placed/ welded in position with the steel reinforcement one meter inside the concrete for better anchoring.

Concrete will be poured using a concrete pump. Vibrator will be used for proper mixing. Concrete will be poured keeping an eye on the JIG to insure that the jig for securing bolts is kept in place as positioning of the bolts is critical to project.

We will pour the concrete in two stages in first stage we will pour up to the lower level and then we will provide the top cap after making sure that the base for anchoring the pylon is level.

As finishing will be required on top one of the skilled worker will act as finisher when the pouring reaches the top.

We will use a dumpy level to make sure that the top is perfectly smooth and in perfect horizontal level as the tolerance is just 3mm

2.2.5 Stage 5-(day16-day19) Striking off formwork and back filling and demobilization

Partly disassembled form work will be lifted out to be completely disassembled to facilitate the commencing of extracting the piles and back filling by the sub contractor.

Foreman shall make sure that the back filling is being done in agreed manner-

Coarse sand is being used for the back fill

Proper layered compaction is being done each layer -200mm

All the provisions relating to health and safety are in place

Due care shall be taken to restore the site to original state ensuring proper disposal of wastes or other materials

Schedule has deliberately been set to coincide the pouring with Friday so that we can start the striking off work next working day after letting it set during the weekend.

We will lift the partially disassembled metal plates out with the help of crane to be completely disassembled on the ground.

Back filling will be carried out by the sub contractor and we shall complete de mobilization simultaneously.

3.1 Resources -

The following resources will be needed for the work:

3.1.1 Materials

Material shall be supplied by the sub contractor (refer Project Plan) as per agreed rates see Appendix-4A

Following materials and equipment will be used in the project:

M11 interlocking piles

Metal plates, nuts and bolts

Hydraulic frames

Braces

Structural steel. - T20, T16 cut and bent, 40mm spacers

Bolts and RSA

C-40 concrete

Binding wires

supports

Coarse sand for backfill- as the earth excavated is mixed soil comprising mainly of silts and clay unsuitable for backfill

3.1.2 Equipments and plant

Following plant and equipment shall be required to complete the project:

Earth moving equipment for excavation viz. JCB excavator

Dump truck for dumping the excavated material

Trucks for transportation during mobilization and demobilisation

Pumps to suck out water

Concrete pump

Vibrator/ poker

Pile hammer

Formwork and braces

3.1.3 Human Resources

Following manpower is required for the project

Project manager in charge of the project, Supervisor to over see the work, Gangers to lead the workers, Skilled labor to secure the trench with the help of M11 piles, erect the form work, fix the steel mesh, assemble the bolt jig, place the RSA and finish the top level and general labor for general work and help to skilled workers -refer Project Plan

4.1 Potential Construction Impacts

The potential construction impacts resulting from construction of foundation include:

• Runoff : Work area is well drained. The investigation report shows that water level is at 4.5 so we don't expect to encounter much water. Pumps will be used to suck the water out, the sucked out water will be drained properly.

• Noise: Most of the work before and after the erection of the form work will be carried out on the site. The site is near some residences. But the amount of equipment and the duration of the work is minimal hence the level of noise will be low. If required, the noise impact may be mitigated by the use of temporary noise walls along the affected boundaries.

• Dust Emissions: Dust is likely to be emitted during dry and windy days and affect the nearby residences. Dust should be controlled by water spraying of the site when necessary.

Project execution strategy and method are also discussed in Project Plan-document-
