Construction Sequence

It becomes necessary, therefore, to Identify these components (units of work/items of work) first. It is not a difficult job. One has to only observe/visualize the sequence in which any construction project is performed. The components can be seen to emerge out and identification  is simple. Moreover, preparing the construction sequence ensures that all activities relating to construction are identified without any omission. 

For example, in a building project, the following sequence of work can be observed : 

• Clearing of the site 
• Marking the foundation lines including construction of centre line pillars and establishing bench marks 
• Earthwork excavation for foundation 
• Tamping and compacting the excavated surface 
• Filled with sand 
• Laying foundation concrete 
• Construction of substructure 
• Refilling the sides of foundation etc. 

A fairly experienced engineer/supervisor should be able to write down the sequence of construction of a particular building project without much of difficulty. Generally, the sequence of recording measurements follow the sequence of construction but it is not a necessity.
