Project Background

The proposed Marina Coastal Expressway (MCE) is approximately 5 km in length, connecting Kallang - Paya Lebar Expressway (KPE) / East Coast Expressway (ECP) in the east and Ayer Rajah Expressway (AYE) at South Quay Viaduct (SQV) in the west. The construction works will be divided into 6 design-and-build civil engineering contracts.  
The advanced engineering study for MCE is divided into three phases (Phase A, B & C).  Phase A study was completed by Parsons Brinckerhoff Pte Ltd (PB) in early 2007.  Phase B and C studies were subsequently also awarded to PB.  YWL Engineering Pte Ltd (YWL) was engaged by PB as the viaduct specialist sub-consultant for further evaluation and development of the interface structure at AYE and SQV based on the selected scheme in the Phase A study.

Services provided by YWL

YWL Engineering provided the advanced engineering study of the interface works with existing Ayer Rajah Expressway using reinforced void deck at South Quay Viaduct which will form part of a design-and build contract for the proposed Marina Coastal Expressway (MCE) viaduct structures, inclusive of

1. Review the reports, plans and drawings as submitted under Part A study
2. Propose feasible construction methods at the interface
3. Assess the structural adequacy and integrity of the existing AYE viaduct at interface with the proposed viaduct

4. Prepare instrumentation and monitoring scheme

5. Investigate the project risk in relation to the viaduct construction
