WOLMERTON ROLLING STOCK DEPOT: UPGRADE - PHASE 3PROPOSED PRASA AMENDMENTS

No. ORIGINAL CLAUSE IN RFP REVISED CLAUSE IN RFP REASON FOR REVISED CLAUSE

3.1.1 2.1.4.2.1 Design and construct a new maintenance running shed – approx. 300 m long to accommodate three (3) new rail lines. The width and height of the shed is to be determined from the detailed design that needs to be done.

2.1.4.2.1Design and construct a new maintenance running shed – approx. 300 m long to accommodate three (3) new rail lines. The width and height of the shed is to be determined from the detailed design that needs to be done. THIS NEW MAINTENANCE RUNNING SHED MUST BE COMMISSIONED AND HANDED OVER TO PRASA FOR OPERATIONAL PURPOSES NINE (9) MONTHS AFTER APPOINTMENT OF SUCCESSFUL CONTRACTOR.

Sixty (60) new PRASA train sets (6-coach) will have to be accommodated at Wolmerton Rolling Stock Depot by end of March 2020. Therefore, the new maintenance-running shed must be completed and handed over to PRASA for operational purposes nine (9) months after appointment to accommodate these new train sets for maintenance purposes.

3.1.2 2.1.4.2.13 - Install a 1-ton monorail crane dedicated for each of the six bays. The shed roof structure must be strong enough to accommodate these mono cranes.

2.1.4.2.13 Install a 1-ton monorail crane dedicated for each of the three (3) bays on the eastern side of the new shed (so-called platform areas). The shed roof structure must be strong enough to accommodate these monorail cranes.

PRASA amendment:The specification was shared with GIBELA, as the end user of the facilities. During a later meeting with GIBELA it was realised that it is not necessary to install 1-ton monorail cranes on the western side (so-called “swimming pool” areas) of the new rolling stock maintenance-running shed. The main reason for this is that it will not be safe enough for technicians to work on the train roof structure in this area of the shed. Therefore,

3.1.14

2.1.4.25.15 Install a guard monitoring system in the depot (bloodhound).

2.1.4.25.15 Install a guard monitoring system in the depot (bloodhound or similar).

PRASA amendment:PRASA is not allowed to refer to a specific brand, which is why the word “similar” was added to the sentence.

3.1.15


2.1.4.29.18. Forty (40) carports must be constructed next to the road at the existing train drivers’ facilities. Cantilever structures with chroma deck roof sheeting. The parking facility must also be paved.

PRASA amendment: The project team realised that this was not included in the original RFP but is definitely required and therefore bidders should price for it.

3.1.16


2.1.4.29.19. The existing "caged" carports must also be refurbished. All fences to be replaced with new steel mesh fencing and all gates and structures to be repaired and repainted.

PRASA amendment: This item was added to ensure that all bidders understand that existing “caged” carports are part of the Train Drivers’ Facilities that need to be upgraded. We have added specific requirements to refurbish these “caged” carports.

WOLMERTON ROLLING STOCK DEPOT: UPGRADE - PHASE 3AMENDMENTS DUE TO BIDDER QUESTIONS

No. ORIGINAL CLAUSE IN RFP REVISED CLAUSE IN RFP REASON FOR REVISED CLAUSE

3.2.1 2.1.4.14.5 - The Tshwane Municipality provides the electrical supply to the existing electrical sub-stations in the depot. For a backup system, a switchgear must be installed between the OHTE electric system and the mentioned electrical substations.

2.1.4.14.5 - Wolmerton Depot Facility and the OHTE are using different sources of power; the Depot Facility is fed from the Tshwane MUN 11kV supply and the OHTE 3kV DC Substation at Wolmerton is fed from the Eskom 88kV supply. The requirement to link the two supply systems entails constructing a second 11kV Substation from 88kV Eskom supply so that the Wolmerton Depot Facility can have 11kV ring feed that will provide a more reliable power supply to the operations of the Wolmerton Depot Facility.

Bidder question:It was a bidders’ question and PRASA realised that the original scope of work request was too vague, and more detail regarding the installation of the switchgear must be forwarded to the bidders.

3.2.2 2.1.4.32.2 An automatic signalling system must be installed at the depot with its own control room. The new signalling system must be able to accommodate 128 (6-coach) train sets as well 62 (12-coach) train sets inside the staging yards.

2.1.4.32.3 An automatic signalling system WILL NOT BE INSTALLED AT THE ROLLING STOCK DEPOT. A control room must be constructed to in future accommodate an automatic signalling system.

Bidder question:The Signalling Department is still in a process of installing a new signalling system on the metro rail main lines next to the Wolmerton Rolling Stock Depot. The proposed new automatic signalling system can therefore not yet be linked to the new system.

Therefore, the signalling system at Wolmerton can only be installed when the new Siemens signalling system is installed in the Pretoria North area.

of 43

PRASA call for a separate tender to appoint a consulting company that will design the new signalling system at Wolmerton depot to ensure that there is a seamless integration between the two signalling systems.

3.2.3 2.1.4.32.3The new automatic signalling system in the depot yard must be compatible with the new mainline signalling system installed in the Wolmerton area. (to cater for depot tie in into mainline)

2.1.4.32.3 An automatic signalling system WILL NOT BE INSTALLED AT THE ROLLING STOCK DEPOT.

Bidder question:An automatic signalling system will be installed at the depot in 2021, after a signalling design consultant is appointed and a detailed design is completed.

3.2.4 2.1.4.32.4 - The two existing rolling stock staging yards, including its entire infrastructure, (fire protection, lighting, storm water system, perway and OHTE) need to be upgraded/replaced.

2.1.4.32.4 The test rail line remains unchanged. Upgrade water and storm water facilities at the test line area. All other perway lines to be upgraded inside the depot as follows: Order only 5 km of 48 kg rails for replacement of existing rail lines where needed. 2.1.4.32.4.1 Replace all wooden sleepers. Therefore you have to order 77 000 (P2) concrete sleepers and the spacing between these sleepers must be 650mm.2.1.4.32.4.2 Order 31 000 m³ ballast for this project. 2.1.4.32.4.3 Only 30 turnouts of 87 need replacement (Type: 1:9 Secant on concrete sleepers). 2.1.4.32.4.4 The electric OHTE contact

Bidder question. PRASA realised that the statement is too broad and could cause uncertainty in pricing. More detail was therefore sought from end users.

wire must remain as is. 2.1.4.32.4.5 Paint all electrical masts and replace cracked or damaged electrical mast foundations. 2.1.4.32.4.6 Ensure all rail earthing is properly done. 2.1.4.32.4.7 Refurbish the fire protection, high mast lighting and storm water systems inside the staging yards. 2.1.4.32.4.8 Formation work is not necessary in the existing staging yard.


2.1.4.32.13 Design and deploy a Wi-Fi MESH System covering all areas of the staging yards to provide connectivity for trains as well as personnel. The Wi-Fi solution must also cover rail lines outside the various running and lifting sheds for up to 250m.

Bidder question:General requirement for ICT hardware and software was included with a specification developed for Paarden Eiland. Bidders question, more clarity and detail provided.

3.2.6 2.1.4.34.3 The upper level will accommodate the new train control room with three (3) offices. The control room must be equipped with the necessary equipment to allow the train operations offices to manage the shunting of the trainsets inside the depot.

2.1.4.34.3The upper level must accommodate the future train control room with three (3) offices.

Bidder Question:Although the automatic signalling system will not be installed at Wolmerton Depot as part of this project, however, the control room must still be constructed to accommodate the new automatic signalling equipment in future.


2.1.4.35.7 DATA RETENTION: The proposed AVI solution must retain data for a period of up to 5 years.

Bidders question:More clarity and detail provided to reduce uncertainty in pricing.
