The performance of the PER were analysed based on the weak areas of the project. The elements that have a definition of 3, 4 and 5 are considered to be weakly defined areas. Since the projects evaluated are at execution phase, these areas a risk mitigation strategy must be out in place, for the weakly defined areas. The results of the PDRA reflect the score of the PDRI 3 and PDRI 4, however in this section we analysing the final scores of the PDRI 4- ERA DV.
Definition Levels
0 = Not Applicable 2 = Minor Deficiencies 4 = Major Deficiencies
1 = Complete Definition 3 = Some Deficiencies 5 = Incomplete or Poor Definition
Project A
Section 1: BASIS OF PROJECT DECISION
Figure 12: Section 1 level of definition per elements. Element D3, D4, D6 and E3 are low in definition. D3- Site Characteristics: Available vs. Required D4-Dismantling and Demolition Requirements E3- Design for Constructability Analysis
56
D3, D4 and E3 – Where affected by the same document. The demolition and construction report was available, but it was not yet signed before Execution Release Approval (ERA), they received a low score. Demolition and Construction Report is a document themethodology on demolition to be covered thoroughly in the report to be authorised.
D6- Project Schedule
The schedule was not yet fully developed and signed at ERA. This put the project at risk of missing the targeted time, because there was limited number of outages available that the project can utilise to complete project work. For next 5 years from the time of PDRA, they only had two outages scheduled for power plant. Add risk to risk register and manage accordingly. The corrective action was to update and maintain schedule as project progress. It also had to ne capture in the risk register of this project.
In Section 2: Basis of Design
Figure 13:Section 2 level of definition per elements Element F3, G8, G10, H, J1, J2
F3- Environmental Assessment
Basic assessment was completed and submitted to the Department of Environmental Affairs (DEA). It scored low because it is still waiting for final authorisation by the DEA. This is a risk that is ranked low, because it is expected the
57
DEA, will accept the proposal as they encourage this type of projects to reduce emissions.
G8- Plot Plan
Plot Plan drawing was completed and signed, but the date it was on was not indicated, so this had to be confirmed. This is important for keeping records of decision taken for the project.
G10- Low Pressure Services (LPS) and Electrical Basic Design, where not signed yet. This implies the designs were not yet authorised. This usual implies that the elements of the design is not yet finalised.
H- Equipment Status
To be completed in next phase, at execution.
J1- Loading/Unload./Storage Facilities Requirements J2- Transportation Requirements
J1 and J2 - Where affected by the same document. The demolition and construction report was available, but it was not yet signed before ERA, they received a low score.
K2- Logic Diagrams
Control and Instrumentation (C&I) basic design, where not signed yet. This implies the designs were not yet authorised. This usual implies that the elements of the design is not yet finalised.

Section 3: Execution Approach
Figure 14:Section 3 level of definition per elements Elements N1, P, P1and P2 are low in definition N1- Project Control Requirements
Project Management plan (PMP) was not signed. P1- Client Approval Requirements
PMP was not signed at the time of the assessment. The PMP expands on the list of crucial deliverables to be signed off and authorised by the client.
P2- Engineering/Construction Plan & Approach
The demolition and construction report was available, but it was not yet signed before ERA, they received a low score
59 Project B
Section 1: BASIS OF PROJECT DECISION
Figure 15:Section 1 level of definition per elements Elements A2, D6, and E3 are low in definition A2: Maintenance Philosophy
Maintenance philosophy did not currently exist, because of the change in technology of the equipment. Supplier was expected to provide new maintenance philosophy for the new equipment.
D6: Project Schedule
The engineering schedule was not resource loaded. Engineering schedule contains activities of the engineering team during the execution phase.
E3: Design for Constructability Analysis
The PMP did not contain information about element E3, so it had to be revised and authorised reflect element E3.
60
Section 2: Basis of Design
Figure 16:Section 2 level of definition per elements Elements F3, F4, G8, G12, H and K2 are low in definition
F3: Environmental Assessment
EIA, was conducted, submitted to DEA, a letter of compliance with environmental requirements from (DEA) was still outstanding at the time of the assessment.
F4: Permits, Licences & Authorizations Planning
The list was incomplete, had to be finalised after completion of the scope of Work (SOW).
G8: Plot Plan, according to the results its well defined, but the graphic display indicates otherwise. (Conflict)
The location for the new equipment was not yet identify. G12: Specialty Items Lists
The SOW was incomplete; it did not include piping specialty items list. H: Equipment Status
The bill of quantities (BOQ) was not developed at the time of assessment.
K2: Logic Diagrams - according to the results its well defined, but the graphic display indicates otherwise. (Conflict)
61
Section 3: Execution Approach
Figure 17:Section 3 level of definition per elements Elements N2, P, P2, and P4 are low in definition N2: Project Accounting Requirements
This element was not yet developed and captured in the PMP. This is due to the new technology being used in some equipment. A Request For Quotation (RFQ) will have to go out to the market, to be able to conclude this element’s requirement.
P: PROJECT EXECUTION PLAN
According to the results it is well defined, but the graphic display indicates otherwise. P2: Engineering/Construction Plan & Approach
According to the results it is well defined, but the graphic display indicates otherwise
(Conflict)
P4: Pre-Commission Hand-over Sequence Requirements.
According to the results it is well defined, but the graphic display indicates otherwise.
62 Project C
Figure 18: Section 1 level of definition per elements Element D6 is low in definition

Project schedule existed, it just be updated and maintained

H1- Equipment status
63
Figure20: Section 3 level of definition per elements Elements M1, M2, M3, N2 and P are low in definition M1: Software Requirements
Construction management still had to define the required software. M2: Deliverables Defined
The list of expected project output deliveries still had to be defined and documented. M3: Distribution Matrix
The distribution matrix has to be developed, it specify who should receive the copies of documents at which stage of the project.
