Route Package Structure

Under the BCM, bus routes are grouped into bus packages, each comprising one bus depot, approximately 20-30 bus routes, several bus interchanges/terminals, and the buses required to operate these routes. All bus infrastructure is owned by the Government, and the Land Transport Authority (LTA) oversees the contracting of these bus packages. The process involves selecting a bus operator through a competitive tendering process and leasing these assets to the successful operator.

The chosen operator is responsible for operating the designated bus routes, collecting fares on behalf of LTA, and maintaining the associated bus infrastructure, including buses, onboard equipment, depots, interchanges, and terminals. In return, the operator receives an operating fee from LTA and may also qualify for bonuses through an incentive framework.

The Bulim Bus Package mainly features bus routes originating from Tengah, Jurong East, Bukit Batok and Clementi Bus Interchanges, terminating at locations such as Boon Lay, Marina Centre, Shenton Way, and Toa Payoh.

Current Term

Tower Transit has been the incumbent operator since May 2016 and will remain so until at least 2026.

It previously operated Bulim Bus Package (Contract PT200) from May 2016 to May 2021.

PT217A – Bulim Bus Package (Current Term: 2021 to 2026):

Presently, the Bulim Bus Package is operated by Tower Transit under Contract PT217A, which commenced in May 2021. This is Bulim’s second tendered contract term, a continuation of the first term (2016 to 2021) previously awarded to Tower Transit.

Bidding Procedure:

Six bids were submitted by five operators as follows:

No. Company Bulim only:
Bid Price (5 years)
Sembawang-Yishun only:
Bid Price (5 years)
Bulim + Sembawang-Yishun:
Bid Price (5 years)
1 SBS Transit Ltd (Alt)* $443,133,709 $567,294,369 $1,003,089,771
2 SBS Transit Ltd (Base) $446,227,073 $569,935,356 $1,008,839,217
3 Tower Transit Singapore Pte Ltd $482,432,845 $582,062,354 $1,025,102,939

  • The price for five years comprises one-off pre-operation costs, as well as the total service fee and lease charges for assets provided by LTA (excluding any adjustment for inflation, change in wage levels and fuel costs, service variation or incentive payment during the contract period).
  • *SBS Transit’s alternative proposal differs from the base proposal by having fewer bus captains and lower non-revenue mileage, to be achieved by launching buses from other bus depots under its negotiated contracts. This is similar to SBS Transit’s existing arrangements at Ulu Pandan Bus Depot.
Contract Award:

On 30 September 2020, LTA awarded Tower Transit both Bulim & Sembawang-Yishun Bus Packages. Tender submissions were evaluated based on a two-envelope process which looked at both quality and price factors. The price submissions were only opened after the quality evaluation was completed.

The LTA press release indicated the reasons for the award:

  • Received the highest total score taking into account both price and quality factors in its proposal.
  • Demonstrated an excellent understanding of the operational considerations and a strong commitment towards enhancing inclusivity and commuter experience on public transport.
  • Strong competence in bus service scheduling that will enable the optimal deployment of buses and resources.
  • Plans to work with the relevant agencies, such as the Public Transport Council and social service agencies, to introduce a Public Bus Confidence Course to familiarise the elderly and less mobile commuters with the use of public bus services.
  • Plans to hire more persons with disabilities as its customer experience and inclusivity officers to leverage their personal experience in challenges faced by this group of commuters on public buses, to help identify gaps and enhance inclusivity for bus infrastructure and services.
  • Commitment to concentrate its recruitment efforts on building a stronger Singaporean core.
Transition to Bulim Bus Package (PT217A):

Tower Transit, as the incumbent operator of the previous Bulim Bus Package term (PT200), saw minimal changes with the transition to the new term PT217A on 29 May 2021. Tower Transit retained the operation of Bulim Bus Depot and the management of Bukit Batok and Jurong East Bus Interchanges.

As part of the new term, three existing bus services previously operated by SMRT Buses (653, 657, and 944) were transferred to Tower Transit. Bus Service 974 was transferred to SBS Transit, allocated to the Jurong West package. Additionally, Tower Transit operated Service 663 until 5 September 2021, when it was transferred to the Sembawang–Yishun package.

In Tower Transit’s bid for Contract PT217 covering the Bulim and Sembawang-Yishun Bus Packages, bus services under these packages may be garaged at either Bulim Bus Depot or Mandai Bus Depot.

    Bulim intake of ADL Enviro500 is way too much and most of the buses deploy on Jurong East service instead.They should lease back 10 more B2 Euro5 A22 for Bukit Batok service and the Citaro can go back to serve Jurong East.Best if 106 & 189 go full DDs.

  • 25 February 2022 at 11:56 AM

    Clementi services, as well as 79, 651 and 657, should be given to SBST. In exchange TTS can take 51, 52, 105, 160, 197, 506 and 852

  • 1 June 2021 at 6:37 PM

    They are shortage of SDs..It’s best LTA lease them 10 Euro6 A22,Put 15 B9TL SG plate into storage and lease back 12 A95 3-door.
