Week 2 Estimation of the overall cost of the project.
2.1 Cost estimation of inputs.
This involved the use of the work breakdown structure. The resources rates were allocated as given by the pool designer, the constructor, and accountants. These parties gave information concerning the cost of the required resources. The expert’s information was also considered. He gave information or the estimated costs of the project based on his experience and the duration that the project will last. Publications on the estimated cost were also considered. These publications gave sufficient information on chart accounts and cost of risk.
2.2 Estimation of the projects’ output.
The costs of output were provided by the expert. He refined the estimated cost provided by the accountant, designer and constructor. We further analyzed the results of the estimated costs by considering all the supporting details. The final stage dealt with the development of a cost management plan (Dobson, 2003).
Activities involved
3.1 Site selection
The site selected was the backyard of the house that receives direct sunlight all through the day.
3.2 Excavation and Exterior development.
The pool area is excavated in the desired shape, and a space for setting the exterior forms is left. The exterior concrete forms begin in setting the concrete pool. Exterior forming involved setting the wall concrete.
Week 4 Steel placements
After the forming of the exterior concrete is formed by leveling and squaring, steel is placed on a grid by following the instructions of the local codes.
Week 5 Interior forming
Once the plumbing, steel reinforcement, and exterior forms were in place, the constructors were then able to set the interior forms. They used Swim Crete parapet bracket for suspending the interior concrete, and a minimal interior bracing was used.
Week 6-8 Concrete placement
Due to the large scale amount of concrete to be placed, the activity took a period of three weeks. The interior section of the pool and the outer ground all require concrete placement. This took place after plumbing, steel reinforcement, and steel placement. Other needed forms were in place. This enabled the placement of concrete done on the swim-Crete system. The constructor recommended 3” or 8 cm of concrete level for the monolithic pool pours.
The placement of concrete into concrete forms of 8 cm slump started at the deep end walls. Once this section was filled with concrete, there was the vibrating of the walls. This enabled the concrete to move below the interior forms. Further placement of the concrete continued to the deep end section of the pool, placing concrete up to the level where the floor and wall come together.
Finishing concrete involved finishing the floors and continuing will concrete placement on the walls. When the concrete had received minimal strength, the tie ends are broken, and forms are removed. A two days period was given to make the concrete walls and floors dry ready to be tiled and plastered. After the two days, finishing was ready to be done through, tiling, plastering, and epoxy maintained among other methods of finishing.
Week 9
Water is opened to the pool. Outer decorations were done such as planting trees, putting rocks and pebbles and use of carpeting grass.
Week 10: Evaluation
This is the final stage that dealt with revising of the cost estimates. The budget is updated, and other corrective actions are made when there is a gap between the estimated costs and the actual costs. Finally, there was the calculation of the Cost Performance Index and the Estimate at Completion (Liberzon, 2012). The Cost Permanence index involved looking back at the roles played by all parties involved in the project. This was to find the effort used by the team in completing the work, each of the team members had been assigned specific roles to do in the project. The actual needed for completing the project was entered. This involved looking at the actual starting and finishing data, the regular cost and units and the expense costs. The actual resources were also included, and viewed if the initial resource matched with the others needed in the swimming pool construction process.
