- 2. 2 TIME IMPACT ANALYSIS Itis a method used to determine the extent of impact from potential delay in the construction process. It involves inserting additional activities indicating delays or changes into an updated schedule representing progress up to the point when a delay event occurred to determine the impact of those delay activities
- 3. 3 TYPES OF DELAY EXCUSABLEDELAYS It occurs when the affected party is allowed to claim for a time extension, compensation, or both. NON-EXCUSABLE DELAYS These are delays that the contractor or the affected party needs to bear responsibility for

- 11. SAMPLE UPDATE 4thMONTH UPDATE DATA DATE DEC 26 2023 The contractor caused a delay in “ Garage Walls” – a non-critical activity
- 12. SAMPLE UPDATE 4thMONTH UPDATE DATA DATE DEC 26 2023 The contractor caused a delay in “ Garage Walls” – a non-critical activity As long as the activity has available total float it will not affect the final completion date
- 13. SAMPLE UPDATE 5thMONTH UPDATE DATA DATE JAN 22 2024 The owner caused a 28-days delay on “Garage Doors”
- 14. SAMPLE UPDATE 5thMONTH UPDATE DATA DATE JAN 22 2024 The owner caused a 28-days delay on “Garage Doors” The delay moved the critical path by 7 days. The rest of 21 day-delay was absorbed by the remaining available float. Then, there will be only 7 days of “excusable compensable delay.”
