rate of progress

What do you expect with the last 10% of the works?

1. If I am a contractor, and my contract has 10% retention, I’ll see to it, that I can make profits in the first 90% of the works.

2. The last 10% is a gamble - if it can be claimed, then it’s my bonus.

3. If I feel that the customer can still sustain the last 10% to go along to another 90%, then, this would be a different story. I will hire an expert! (of course in contracts!)

What’s a tail-end of progress?

cheers!

Tail end of the project :

Are you refering to the last horizontal section of the S-Curve? if yes then they are not always as they are seen on the S-Curve. the work usually is dont till the last date and the almost horizontal section is very rarely achieved.


Usually projects, exceeding 3 to 4 months go for running invoices. and if this is the case with your project too then u need not worry abt the last 10%

Stephen,

It’s very hard to make a generalisation of this nature:
-The %age weighting used to define the ’last 10%’ will usually be a factor of cost to the contractor, or just labour resources.
-The tail end of the project will usually consist of commissioning and snagging. Commissioning requires no (or at least minimal) plant or materials, and little contractor labour, hence it often has a low %age weighting compared to the importance and duration. Snagging often carries no weighting at all since it’s work that should have been done right first time.
-But how long the commissioning & snagging will take as a %age of overall duration depends entirely on the project. It could be a 12 month project with 3 month’s commissioning, it could be a 5 year project with numerous sectional completions meaning the final section’s commissioning is only a month. It could be a process job where commissioning includes a 3 month proving period, it could be a single-story car park where commissioning is little more than checking the lights work.

Cheers,
