How do you prepare a Time Impact Analysis in a construction project ?

Time impact analysis is done using exesting scudual, analyzed with all related input entered into the schedule to demonstrate the reason or possible effects on schedule. determine extent of impact from potential delay in construction process. promote negotiation and later agreements on delay claims

To claim (EOT) by time impact analysis, All delay events are collected from different documents (Shop Drawing, material, RFI, IR, MIR Logs, Correspondences, minutes of meetings, Daily, Weekly, Monthly and obstructions reports etc.) month wise.

The delay events are included into approved Baseline/updated program to creat fragnet schedule at different time intervals and affect of fragnet schedule is noted. Update impacted schedule and affect is noted. The delay from both programs will be considered delay on of parties (Contractor or Client). A serioes of fragnet schedules are created by delay events at different time inetrevals and net delays calculated. At the end of last interval, overal net affect is conisdered as claim for EOT if valid. Following are the steps involved.

1) Develop and approve schedule fragnet to model the extra work

2) Obtain the most recently updated approved schedule

3) Set the durations of the extra work activities (fragnet) to zero.

4) Insert the approved durations into your fragnet (schedule of new work) and recalculate the critical path.

5) Identify the activities used to measure the delay

6) Determine the correct time impact of delay

7) Determine the actual dates of the delay

8)  Lastly eliminate any delay that was already in the schedule

 

When performing a time impact analysis be sure to:

1. Study and understand the scope of the directed change or analyze the extent of the delay being found.
2. It is important to analyze all documents, field directions, contract clauses, drawings, orders, specifications and conditions that could exert any kind of influence to the expected delay.
3. Identify and describe the condition encountered before performing the time impact analysis.
4. Identify all related construction activities that are or could be affected under the expected delay.
5. After a complete analysis of the construction schedule, determine all related dates, start, duration and finish, for all affected activities.
6. Prepare a complete set of documents that define when the delay started, what actions took place at that moment, and demonstrate the effects of the delay on the actual updated schedule and how the remaining activities should be altered, if required, to complete the project on time.
7. The time impact analysis could present you with the overall schedule result incorporating drawings, contract requirements, and any type of document that support final conclusions. It is important to highlight extraordinary measures required to bring the project back on schedule.
8. Be certain that actual delays are result of the change directive or delay, not from a non-excusable cause.

Hi,

Time Impact Analysis is a method used to determine the extent of impact from potential delay in the construction process. This schedule analysis method 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.

Time impact analysis involves interim assessment of delay on updated schedules, and concentrates on a specific delay or delaying event and it’s impact on completion date in real time. Whenever the project experiences a major delay situation, a stop-action picture of the project is developed. The schedule is then updated at this delay period and the effect of the delay is analyzed to establish a new completion date. The difference between the new completion date and the date prior to the exercise gives the delay caused by that particular impact. It is more effective technique because the delays are analyzed using real time updated Critical path network.

 

Outline the contract payment schedule and Scope of Work. Determine resources requirements (Manning/Equipment/Materials) and lag time (Holidays/Scheduling/Procurement) for the specific task (project). Sync those tasks up to critical path/sequence of events. Time Impact Analysis estimates baseline and potential slippage. Add cost to forecast cash outflow (cognative of vendor terms). And, Add billing to forecast cash inflows (cognative of customer terms).

reasonable assumptions about your business in establishing your budget. You will need to ask questions such as: How much can be sold in Year 1? How much will sales grow in the following years? How will the products and/or services you are selling be priced? How much will it cost to produce your product? How much inventory will you need? What will your operating expenses be? How many employees will you need? How much will you pay them? How much will you pay yourself? What benefits will you offer? What will your payroll and unemployment taxes be? What will the income tax rate be? Will your business be an S corporation or a C corporation? What will your facilities needs be? How much will it cost you in rent or debt service for these facilities? What equipment will be needed to start the business? How much will it cost? Will there be additional equipment needs in subsequent years? What payment terms will you offer customers if you sell on credit? What payment terms will your suppliers give you? How much will you need to borrow? What will the collateral be? What will the interest rate be?
