| OP/EC/3.3 - Post Project Economic Evaluation of Development Projects |
| |
Purpose and Scope :
The post project economic evaluation compares baseline conditions in the study area with those resulting from the project. This evaluates the achievements of the project against the predicted outcomes. The evaluation is highly dependent on the accuracy of the baseline data and may include the assessment of impacts on traffic, socio-economic indicators, environment, flooding and other parameters depending on the project objectives. |
| |
Definitions :
Post Economic Evaluation – comparison of out turn economic impacts of completed project with predicted impacts from feasibility study; vital to the understanding of the success of the investment and for designing future projects.
|
| |
Responsibility :
Chief Transport Economist – approves survey programme and budget.
Executive Transport Economist – Economic Feasibility Studies Division – designs and plans the field surveys, analyses the data and prepare the report.
Assistant Transport Economist – Economic Feasibility Studies Division – conducts field surveys. |

Method :
4.1 DEFINE SCOPE OF STUDY
The request for a post project evaluation will normally be received from the MOC. The CTE and ETE – FSD will review the baseline data and define what surveys are required to collect post project completion data. They will write terms of reference for the works to be undertaken either by the Circle or Consultants. The ETE-FSD will define a budget for the study, which will agree by the CTE.
4.2 BUDGET APPROVAL AND APPOINT CONSULTANT
The CTE and ACE Planning & Maintenance Wing will decide whether the works will be conducted internally or externally and agree a budget. If the works are to be conducted externally consultants will be appointed in accordance with OP/PC/2.4.
4.3 CONDUCT SURVEYS
Traffic surveys may include traffic volume, origin/destination, axle load and travel time surveys. If conducted in-house the Assistant/Sub Assistant transport economist will hire the survey personnel required, train the team and conduct the surveys according to the RHD traffic counting manuals. Other surveys may include socio-economic impacts; at the time of writing the requirements for these had not been defined.
4.4 ANALYSIS
The analysis will be undertaken in accordance with international best practise; no RHD procedures existed at the time of writing.
4.5 PRODUCE REPORT
The results of the study will be prepared in hard and soft copy and distributed to those requested and CE-RHD & ACE Planning & Maintenance Wing. |
