Role of constructability review in the delivery of power system projects

Role of constructability review in the delivery of power system projects

By Idowu Oyebanjo

A constructability review workshop aims to integrate engineering design, executive knowledge and experience with programme implementation in order to better achieve project objectives.

More broadly speaking, Constructability Review is a project management technique to introduce “construction thinking” or “build-ability thinking” into the design phase of the project.

Its purpose is to anticipate and identify challenges to the actual construction of the project before a project moves on from the design phase.

A typical agenda for the constructability and risk review session for a power system project is as indicated below:

  1. Welcome & Introductions
  2. Risk Matrix A: Shipment & Transportation to Site – Covers Pre-shipment, Custom Clearance, Transportation to site, Route survey, Security, Port Congestion, etc.
  3. Risk Matrix B: Construction Design Management (CDM) – Covers Outage Management, Ease of installation, Site Safety & Security. Work Programme of Contractors, Implementation Plan, Programme Management etc.

Sample Constructability Review Meeting – Ajah Transmission Substation, Lagos

Ajah Transmission Substation will get a total of over 120MVA of transformation capacity added to the national grid via the deployment of a 60MVA, 132/33kV Power Transformer and a first of its kind 63MVA, 132/33kV mobile substation, designed, manufactured, and tested by Siemens under the Presidential Power Initiative (PPI). As the main purpose for building a power system is to satisfy customers, a Constructability Review Meeting to ensure that customers, as much as possible, are not left off-supply during the implementation is key.

The Constructability Review Meeting which took place at Ajah Transmission Substation recently will ensure improved electricity supply to Ajah with focus on Elemoro, Ilasan, Eleko, Ibeju and many more areas.

Stakeholders involved in the Constructability Review Meeting include TCN Operatives in the Lagos Region, and at Ajah TS (Hosts), the team of the beneficiary Distribution Company, Eko Electricity Distribution Company (EKEDC), Oska Jo, Expert Design and Engineering Management Consultants (DEMC), and members of the Project Management Office (PMO) of FGN Power Company of Nigeria Limited. Apart from the Project Manager from Siemens, the Contractorsthat will carry out the installation, testing, commissioning, and energization of both equipment (MBH Power Limited and Cartlark International Limited) were also in attendance.

In view of the importance of reducing the total outage time and ensuring the need to have an effective project implementation, this important meeting discussed all related matters including but not limited to the work programme of contractors, timelines, outage management, safety, risk factors and mitigations, etc.

As a result of this engagement and brainstorming session, consumers will not be off supply while we carry out these installations thanks to the cooperation of TCN and EKEDC who have continued to prioritize the availability of supplies to consumers.

I will tell you more about on-going construction works from time to time.
