Marine and Civil Concrete Remediation
The Port Authority Of New South Wales engaged Silver Raven for the delivery of marine and civil concrete remediation work on the soffit of the berth Working Platform at the Bulk Liquids Berth 1 (known as BLB1) located at Port Botany New South Wales.
The purpose of this remediation project was to extend the working life of the berth by 20 years to the current berth load design limits, by making the required repairs to damaged concrete and steel reinforcement on the soffit of the working platform.
The BLB1 working platform was constructed circa 1975 and consists of hollow tubular steel piles, reinforced one way spanning concrete deck and reinforced concrete beams. The BLB1 was constructed for use as a multi‐product import and export bulk liquids berth and is nearing the end of the original design life.
The berth has undergone structural aging over the years from concrete corrosion, live loadings on the berth as well as generally due to age which has resulted in cracking, spalling, drummy delaminated concrete and loss of steel reinforcement due to chloride ingress (concrete corrosion). The berth continues to experience high occupancy levels and is expected to be serviceable and in use for at least 20 years.
