WBS for a Substation

The construction of a concrete substation is like any other concrete building but you need lots of block-outs. If it is air-insulated, then you have air-conditioning system.

Hi Adi

Just make sure that you can get the kit into the building before you seal it up.

Hi Hady,

Installation works in the substation can be broken into following;

1. Installation

1.1. MEP works inside substation
1.2. Installation of substation equipments (transformers, MDSs etc)
1.3.Power Cable Installation
1.4.Bus duct installation
1.5.Control Cables installation
1.6.Cable terminations.

2. Testing activities

2.1.Transformers and Panels dry check
2.2.Cable testing
2.3.Transformers and Panels testing (protection tests)
2.4.System sequence tests
2.5.Cable HIPOT tests
2.6.Authority Inspection and witness tests
2.7.Final commissioning and Power On

Hope this will help

Planners,


I am preparing a schedule for an 2 nos. of electrical substation here in Saudi Arabia with area = 6000 m2 . Around how many months is the duration of this partion?

Thank You

Dear Pacifico,

It depends on the location and the environmental factors. Say you need 3-6 months for procurement of equipment, and during that time you can get the Civil Structures up.

Say 9-12 months as as starter.

With kind regards,

Samer

Hi Pacifico

Check the long lead material procurement duration with your project team because in substation you will find many equipment on approval of submittal they will undergo factory acceptance test which consumes some duration in some case it is critical

Shahul,

Thank you very much, but im preparing only the construction part of the substation like Civil, MEP and Finishing work without the procurement activities. I’ll just want to know the more or less the duration for Civil, MEP and Finishing for a 6,000 m2 substation.

Thank You
Pacifico
