1 Basic Outline
1.1 Old Tricks
1.1.1 There is nothing new about the Projected As Built method of delay analysis – it is how we did it using graph paper and crayons before programming software came along.
1.1.2 It is time to teach new planners old tricks.
1.1.3 In fact you do not need to be a planner to use this method – even a QS can do it..
1.2 Passive Comparison
1.2.1 The Projected As Built method:
188.8.131.52 Compares the planned intention with what actually happened.
184.108.40.206 Explains the cause of the difference between the As Planned and As Built tasks
220.127.116.11 Projects the Work to Complete to demonstrate the delay effect
18.104.22.168 Enables Common Sense to interpret the results.
1.3 What is Needed
1.3.1 A basic construction program.
1.3.2 A proven list of events.
1.3.3 A basic As Built schedule showing start and finsh of programme tasks.
1.4 What is NOT Needed.
1.4.1 Logic or critical path in the programme – if it is there then ignore it.
2 Facts and Common Sense
2.1 The 5 facts to assemble
2.1.1 Fact 1 – The Contract Duration
2.1.2 Fact 2 – The location in the programme of the delayed task
2.1.3 Fact 3 – The duration of the work to complete plus any total float attached to the task
2.1.4 Fact 4 – The dates and duration of the As Built task
2.1.5 Fact 5 – The dates and duration of the Delaying Event
2.2 Common Sense Interpretation
2.2.1 There will be more than I possible interpretation of the result which will require common sense derived from experience – this article explores 5 possible cases.
22.214.171.124 Case 1 – Employer’s Delay
126.96.36.199 Case 2 – Contractor’s As Built Delay
188.8.131.52 Case 3 – Contractor Uses Float
184.108.40.206 Case 4 – Employer Uses Float
220.127.116.11 Case 5 – Both Use Float
And this is the summary:
1.1.1 The main advantages of the method of delay analysis are:
18.104.22.168 It is based entirely on demonstrable facts which are difficult to challenge.
22.214.171.124 Events can be demonstrated in any order to show individual and/or cumulative effect.
126.96.36.199 It can be used for work in progress or forensic analysis.
188.8.131.52 Issues such as concurrency and float usage are clearly demonstrated.
184.108.40.206 It is valid for any form of contract and jurisdiction.
220.127.116.11 It is so simple that even a judge can understand it.
1.2.1 There is only one disadvantage that I have discovered.
18.104.22.168 Established delay analysts do not like it and will attempt to rubbish the presentation. (actually that is another advantage)
