The Tianjin Port Xinxing Building Materials Terminal Co., Ltd. Industrial Base General Terminal Project (hereafter referred to as the Building Materials Terminal Project) is situated on the southeast side of Plot 10 in the southern area of the Lingang Economic Zone (Gaoshaling Port Area), east of the northern coastline of Zhonggang Pool.
This project involves constructing five 70,000-ton general berths along a total shoreline length of 1,290 meters, capable of accommodating five 70,000-ton bulk carriers simultaneously. The engineering design targets an annual transportation capacity of 10.5 million tons, including 3 million tons of wood, 5.5 million tons of steel, and 2 million tons of other miscellaneous goods.
1. Dock and Water Area Layout
The project will develop five new 70,000-ton general berths with a continuous full-hall design spanning 1,290 meters of shoreline. The wharf surface will be positioned at an elevation of 6.0 meters. The front line of the wharf is set 45 meters from the existing embankment axis, and the land depth measures approximately 680 meters, including the width of the wharf pier cap.
The berthing water area directly in front of the dock is designed to accommodate 70,000-ton bulk carriers, featuring a width of 100 meters and a bottom elevation of -15.3 meters. The harbor basin and turning water area are configured to meet navigation requirements for 70,000-ton bulk carriers, with a bottom elevation of -14.0 meters. Because the Gaoshaling Port area recently implemented navigation standards for 50,000-ton vessels, the bottom elevation is set at -12.7 meters. Looking ahead, the channel is expected to support vessels up to 100,000 tons. Therefore, the harbor basin and turning water area’s bottom elevation are aligned with Gaoshaling Port at -12.7 meters. The ship turning circle has a diameter of 460 meters, which is at least twice the length of a 70,000-ton bulk carrier.
2. Land Layout
There will be three entry and exit channels on the north side of the project land area: one on the west side and two flanking the auxiliary construction area. These channels connect to roads within the Lingang Economic Zone via a planned northern road, ensuring effective collection and transportation.
Within the land area, four north-south channels will be arranged: two with a width of 25 meters on the west side and the east side of the auxiliary construction area, and two others with a width of 15 meters. Additionally, three east-west channels are planned, with the northernmost channel at 25 meters wide and the other two at 15 meters wide.
The gantry crane’s sea-side track centerline is located 3 meters from the front line of the dock, and its track gauge measures 12 meters. Sequentially from front to back, the wharf’s working area, road, and yard are arranged. On the west side of the land, from north to south, are warehouses, general cargo and steel yards, and steel and timber yards. The central land area includes the auxiliary construction area, warehouses, and timber yards, arranged from north to south. On the east side, timber yards, a log quarantine and pest control treatment area, and additional timber yards are arranged sequentially from north to south.
3. Auxiliary Construction Area
Located on the north side of the central land area, the auxiliary construction zone primarily comprises business offices, waiting buildings, machine repair workshops, tool warehouses, water supply regulation stations, sewage treatment facilities, a substation (#1), and communication base stations (reserved land only; investment not included in this project). It is divided into distinct zones according to function, including office, production, and support facilities.
The log quarantine and pest control treatment area is situated in the northern part of the eastern land side. The flow machine parking area is positioned on the southeast side of the auxiliary construction area, also serving as a buffer zone for port vehicles.
Application of BIM Technology
As a BIM consulting firm, we plan to deliver a comprehensive suite of engineering consulting services for this project. These include design scheme refinement, clash detection, 4D construction sequencing, pipeline positioning during construction, and intelligent asset management—all enabled through the use of 3D models.
To ensure smooth BIM implementation, the auxiliary construction unit will establish a BIM project leadership group and working group. These groups will involve representatives from the construction party, agent, design party, supervision party, and construction party. A detailed work plan has been developed to guide the BIM technology application process. Additionally, 4 to 6 experienced BIM consulting technicians will be assigned throughout the project, providing necessary software platforms and bidding technical requirements to all stakeholders.
1. Scheme Stage: Based on the feasibility study report, a conceptual model of the dock and rear yard plan will be created. Renderings and walkthrough videos will be produced to help the construction party better understand the design. The loading and unloading processes will be simulated to assist in selecting the optimal layout and operational plans.
2. Structural Modeling: Revit software will be used to develop a model of the high-pile wharf, integrating components such as beams, slabs, and columns to represent load-bearing elements like beams, longitudinal beams, and foundation piles. This approach provides a clear visual representation of the wharf’s structural design. The general structural segments will be imported into SAP2000 for overall stability analysis, and pile impact tests will be conducted to optimize the structural layout.
3. Model Development: The model will be progressively refined through the feasibility study, preliminary design, and construction drawing stages. It will incorporate elements and data relevant to each design phase. Ultimately, the finalized design model will be handed over to construction management and the construction unit, including all required information to guide the construction process.
4. Equipment Modeling: A model of the dock’s loading and unloading equipment will be established, integrating procurement, installation, and warranty information. This facilitates efficient management by the operations and maintenance team.
