Project Costing Assignment

Introduction

Building a concrete footing for a site where you want to construct your project, in our case the major piece of equipment either a big wall or a supporting building in a process plant.

The basis on which rests the whole building or construction is what is called foundation and the foundation is based on the concrete flooring on which is going to support our process plant as a foundation (base). Rarely these are natural. Most commonly, they have to be built underground. The depth and the width thereof are determined by calculation in accordance with the terrain, the material of which are constructed and the load they have to support. In our case the depth of the concrete flooring required is 1.80 meters which is underneath the earth. The width of the flooring must be according to the requirement i.e. 8 meters and the length of the concrete flooring must be 16 meters. In this way a base for the process plant is to be built.

If we calculate the total volume of the footing then according to the calculated formula it requires approximately around 301.35 Cubic Yards.

The foundation plan also critical from the point of view of its construction. Hence the basis of nothing more than delineates their shape and arrangement.

The simplest consists in tracing the outlines of the foundation and its axis, which are also the walls that rest on them. The shaft is outlined to facilitate the redesign of the foundation on the ground, which is used as a guide for opening trenches. It is common to add to the rendering plant foundation with dashed lines, the width of the walls which rest on it. Variants may occur often in representing walls: only partial representation angles, represented by hatched, etc (Shroff & Shah, 2003, pp. 1-2).

Requirements

The requirements are given as:

1.2 m of working space around the footing and a 45 degree batter to the earth sides (Cacioppe, 2000).

Formwork is required on each of the vertical faces of the footing

After 2 days curing of the blinding concrete pedestrian access and erection of formwork on can commence (Cacioppe, 2000).

Reinforcement is approx 140 kg / m3 of concrete

Allow for 25% bulking of excavated material

Formwork to remain in place for 7 days after concrete pour for concrete to part cure

After stripping formwork, backfill to existing level in 300mm layers

The concrete for the footing must be poured in a single pour

We have the following plant available:

20T excavator with 0.9 m3 bucket that can excavate this material at 40 m3 per hour

Sufficient trucks to keep up with the excavator

Vibrating plate compactors that can compact fill material (to 100% modified compaction) at the rate of delivery and spreading by the 20T excavator.

A concrete pump with a capacity of 25 ...
