On completion the learner will know how to determine methods of working for construction and be able to plan the work.

To carry out a task it is normally possible to do it in a number of ways using a number of different methods i.e. To dig out the trench for a drain run, it can be done either by the use of man power where by it is dug out by hand or it can be done by a machine. The method chosen will depend on the size of the job, how important it is to do it in a given time frame and if there is a piece of suitable plant on site at anytime prior to the trench being dug.
Such consideration will therefore have to consider the following:
From this and your understanding of the processes, which must be completed to construct a building you should be able to break down the Construction Phase into the activities and assess the ways that these are carried out. You would then need to assess the possible methods which can be done by the production of a Method Statement.
A Method Statement is a detailed schedule that considers alternative proposals and makes recommendations on how a task is to be carried out and the resources that will be needed. It considers time, costs and technique for each method of carrying out the work and the resources necessary to perform the major activities in the project.
Prior to the programme being drawn up it is essential to know the following:
When assessing a job it is probable that there will be a number of options for how it can be carried out. The production of a method statement can enable each option to be assessed prior to deciding on the most appropriate method.
A method statement will enable all the resources to be assessed and consequently this can help in the costing of the project. This can be produced as a Method and Resource Statement or as separate forms.
The method statement is best produced at the earliest opportunity as it is used to guide everyone within the contracting firm regarding the method and sequence of construction.
To produce the method statement, the construction work is broken down into operations, and the labour and plant requirements are then estimated by those responsible i.e. plant by the plant manager.
The Method Statement is the basis from which the programmer works in drawing up the Contract Programme. It can also be used on-site by the site manager as it conveys how the work should proceed.
Not all firms produce a method statement as many will rely on the site manager to carry out the work using their experience, this is particularly true in housing developments.
The production of the method statement must consider the contract documents i.e. drawings, specification, Bill of Quantities. If the contract is handed over in stages the method statement will include this.
Once the method statement has been produced it should be adhered to with no deviations without official permission.
The work that is to be done by the contractor and any nominated sub-contractors should be shown on the Statement and it is normal for any sub-contractors to produce a method statement for their work package.
In order to produce a method statement the following Procedure can be used:
List the activities that will need to be carried out in order to produce a method statement and programme to carry out the work for the construction of a detached domestic dwelling. This will include all items from site set-up to hand-over in the order that they are to be carried out.
Having obtained the above information this can be transferred onto the Method Statement. A number of forms can be used and the one below is used as an example.
