Tips on using this forum..

(1) Explain your problem, don't simply post "This isn't working". What were you doing when you faced the problem? What have you tried to resolve - did you look for a solution using "Search" ? Has it happened just once or several times?

(2) It's also good to get feedback when a solution is found, return to the original post to explain how it was resolved so that more people can also use the results.

Hi Everyone,

I was asked to prepare an infrastructure schedule having the following:

1- Road Works
- Geo-Tech Investigation
- Road Works
- Channel Crossing
- Storm Water Drainage
2- Infrastructure
- Sewerage Works
- Street Lighting
- Telecommunication
- Potabel Water System
- Irrigation and Fire Fighting System
- HV & LV Distribution Network

As i have no previous experience with these projects, i just want to know the logical sequence or the link between these trades.

please let me know about any consideration I should take also .

Thanks,

Amr

Hi Amr

With linear projects such as roads and pipelines the work progresses along the chainage so the sequence that Samer has descibed will have to be repeated in sequence along maneageable lengths of the road.

A key factor is the planning and sequencing of haul roads for cut & fill - particularly if they are on the carriageway.

Another consideration is that drainage pipes are generally laid "Up Gradient" which may be contrary to the flow of work for the other tasks.

I would suggest the use of Tilos software for such linear projects although a similar effect can be gained by using PowerProject in "Task per Line" mode.

The main rule in planning is that if you don’t know how to build ask someone who does - not just fromm PP but somenoe nearer your project.

Best regards

Dear Amr,

In three minutes of less,

1. Both will have the following logical sequence.

I. Soil Investigation.
II. Design Drawings.
III. Site Survey.
IV. Material Submittals
V. Shop drawings submittals
VI. Material procurement.

2. In more details:

Road Works
1. Complete cut and fill
2. Fill in layers and testing
3. Install services (E/M)
4. Complete wearing surface (Asphate, Interlocking, concrete)

Infrastructure:
1. Complete Mechanical works
2. Complete Electrical works.

You will need to get with your team members and create the WBS for the works. It depends on the scope outlined in your contract.

With kind regards,

Samer
