INTRODUCTION This office was employed for the electrical investigation and as the electrical engineers on the project to implement, design and construct a transport centre at Trompsburg next to the N1 route south of Bloemfontein in the Free State Province. This purpose of the project is to expand the economy and infrastructure of Trompsburg and the Kopanong Municipality and to create a Hub of activities and economic and cultural expansion. The service report will be for the development of a taxi terminus.which will be discussed in the report 2. PROJECT BRIEF-PROBLEM STATEMENT The Brief of the project is to electrify the taxi terminus and install lighting and power within the buildings and the area lighting. 3. DESIGN CRITERIA/PARAMETERS The scope of works compromises but is not limited to the following: 1. Design of internal reticulation of the taxi terminus area. 2. Design of the lighting layouts within the taxi terminus 3. Design of the area lighting 4. Design of the street lighting 5. Design of the lightning protection installations. 4. WORKPLAN-METHOD The workplan to obtain the design criteria and project brief is as set out below: 1. Have site inspections on the proposed site and evaluate the viability of the site 2. Arrange and have meetings with the relevant parties to discuss the relevant site. 3. Compile Report on the services needed and do a preliminary design.

The site was visited and the proposed site for the development is as indicated in Figure 1 Proposed position for taxi terminus Figure 1-Proposed site As seen in figure 2 the existing Eskom services are indicated. BVI CONSULTING ENGINEERS NOV 2014 Page | 2 31696E-REP001-02 Trompsburg Transport Centre-Electrical Services Report 5.1. EXISTING SERVICES Figure 2-Existing Eskom Services At the site inspection it was found that at the site identified there is a 66kV overhead line situated next to the proposed site on the eastern side and is the property of Eskom It was also found that there is a 11kV overhead line crossing the proposed site and Eskom was contacted and they assured us that this line may be relocated and that an application for relocation of services must be done. The existing Eskom services are indicated in Figure 2-Existing Eskom Services BVI CONSULTING ENGINEERS NOV 2014 Page | 3 31696E-REP001-02 Trompsburg Transport Centre-Electrical Services Report Although Eskom services are in the vicinity of the site the service provider is Centlec. There is a Centlec 11kV overhead line next to the entrance road of the town on the southern side of the proposed site and thus an application for electricity must be done to get a connection from this line. Centlec was contacted and they assured us that a connection up to a certain size may be done from the 11kV overhead line. 5.2. NEW ELECTRICITY SUPPLY As discussed in the above paragraph there is a 11kV overhead line on the southern side of the site that is the property of Centlec and thus application must be done for a new connection from this line If looked at the next paragraph preliminary design and Table 1- Preliminary design loads, a connection size of 150A three phase is needed to supply the proposed new transport centre development. With regards to the town planning documents the erf next to the proposed transport centre will be for a shopping centre development of +- 4000m². This will not require power at this moment but as for the transport centre there is electricity available. On an estimate of 100kVA/m² with diversity it will require a 400kVA connection. Centlec was contacted and they indicated that a connection can take place and that there is availability on the line and that the connection will be in the form of a new pole mounted transformer of ratings 100kVA 11 000 / 400V delta/star will be done if application is done. Further feedback will be received at a later stage with regards to the exact point of connection.
