Management of Construction

Construction Introduction of Contractor selection phase

We have already discussed these analyses in our chapter on planning and design, but now we add this note to indicate that the contractor will also be concerned about possible alternative construction methods. The method statement will contain the results of these analyses, as it will state the intended methods to be used. The basis for these statements will be some detailed analysis of options. Consider briefly our major waterway crossing. In the case of the superstructure components, the analysis is likely to consider the extent of prefabrication. There are cost advantages to producing relatively large components in a more controlled production environment, but there are also extra costs involved in the transport and lifting of these heavier elements. The placement of under-sea concrete can be accomplished in several different ways; the contractor will want to study and evaluate these various methods. In a similar way, alternative dredging methods, including disposal of spoil material, will warrant analysis.
