2 OBJECTIVE

The intention is to enable Eskom’s in-house teams to obtain expert engineering,

project management, project development services and specialised services in a

streamlined process, on an “as and when required” basis.

Eskom’s project life cycle model comprises the following stages and phases:

Pre-planning Project phase: Identify business and technical deficiencies,

needs and opportunities. Identify and screen possible investments which will

add to the capacity of Eskom's electricity business. Devise a variety of

tentative plans to satisfy these. Eliminate obvious non-starters and plan the

way forward for evaluation of those remaining. PDD search for potential

opportunities in line with CS input. Opportunities evaluated and prioritised

according to selected criteria. Recommendations made to Approval

Committee.

Concept Phase

o Opportunity: Narrow down the solution options. Assess risks. Identify

any "Show Stoppers". Develop funding & financial strategies. Identify

and quantify external factors, i.e. primary energy, environmental and

legal and regulatory issues. Address route/siting issues. Second level

cost/benefit analyses.

o Pre-feasibility stage: To narrow the solutions down to a preferred

solution and location. Establish final route/site. Obtain Environmental

Impact Assessment EA. Clear all legal and regulatory requirements.

Quantify costs and benefits to within 10% and establish rate of return

on investment. Finalise user requirement specification. Finalise

economic evaluation

Definition Phase

o Feasibility Stage: To narrow the solutions down to a preferred solution

and location. Establish final route/site. Obtain Environmental Impact

Assessment ROD. Clear all legal and regulatory requirements. Quantify

costs and benefits to within 10% and establish rate of return on

investment. Finalise user requirement specification. Finalise economic

evaluation.


o Business plan stage: To compile a detailed Business Plan and Project

Scope and strategy and to test the scope against the user requirement

specification. Compile the Project Implementation Plan with goals and

strategies and deliverables. Conclude commercial agreements. All

regulatory and legal issues reviewed and resolved. Investment

approval for project obtained.

Execution phase:

o Planning and design stage: Review and expand the Project

Implementation Plan so that it addresses all the key project planning

disciplines. Define and establish detailed project organisation plan and

structure. Finalise designs, establish detailed time-based programme

and detailed Work Breakdown Structure. All planning activities frozen.

o Contracting and procurement stage: Establish equitable and

administrable contract(s) for all aspects of the project, in accordance

with predetermined contracting strategies. All designs and

implementation schedules finalised and integrated into master

schedule. Final cost comparison made to approved cost baseline.

Financial closure and contract signature

o Construction stage: To create the physical asset in accordance with

schedule, designs, contractual commitments, legal and other

requirements. Ensure all work executed within scope, cost, schedule

and quality (performance) ready for commissioning.

o Commissioning and handover stage: To put the plant into service,

demonstrate that contractual commitments were met, and hand over

responsibility for the asset to the Client. To wind down the Project

organisation. Conclusion is on acceptance of the Hand Over document

and plant in commercial operation.

Finalisation phase:

o Close out stage: To close the Project in terms of contracts and

contractors' liabilities. Close out all financial transactions and local

service contracts. Evaluate and report on the execution and

management of the project. Project to become a fully operational part

of the business.

o Evaluation stage: To evaluate the degree to which the project achieved

its execution costs, execution objectives and delivery performance


parameters. Feedback and archival with lessons learnt. Produce a

Finalisation Report.

Post Project: To evaluate the degree to which the development, execution and

operating performance costs and benefits predicted in the Business Plan were

successfully achieved. Close out any financial transactions after the guarantee period.

Feedback and archival with lessons learnt. Produce a Benefits Case Evaluation Report.

General Service:

Panel B shall comprise local BEE compliant multidisciplinary Engineering

services/Joint Ventures. They must be able to cover most aspects of the project

phases of specified technology and/ or be able to conduct power plant operation

and maintenance. The Panel B Engineering service/Joint Ventures may have an

international partner to supplement their service offering.

Panel C shall comprise local SMME Engineering services that are BEE compliant

(including BYO’s, BPwDs and BWO’s), specialising in specific engineering

disciplines and/or maintenance areas.

It is anticipated that prospective tenderers will determine which panel they wish to
