3. Academic Qualifications

In my Msc (Eng) studies, I learned the BD submission process and relevant Building (Construction) Regulations by taking the course “Professional Practice in Building Development” and “Building Planning and Control”.

In addition to taking compulsory courses to obtain the master degree, I also selected and sit in several courses related to structural design and building management to further expand my knowledge and skills in structural engineering, such as 1.  Foundation Engineering; 2.  Advanced Reinforced Concrete Structure Design; 3.  Tall Building Structures; and 4.  Operation and Maintenance of Building and Civil Engineering Works 4.  Design Experience – Graduate Engineer 4.1 Design for “MTR South Island Line East Consultancy Agreement C901 - Admiralty Station and SCL Enabling Works” Client: MTR Corporation Limited. Contract Sum: HK$2,400 million

The project mainly includes a new extension at the east of the existing Admiralty station to accommodate an interchange concourse, circulation areas and plant rooms for South Island Line (East) and Shatin – Central Link (North South Line). My responsibilities in this project are summarized as follows: 

4.1.1 Stability Assessment  

The new extension of Admiralty station was proposed to be constructed as a Cut-and-cover Box founding on pad footings on Grade III rock. Lateral soil, water and rock forces were counter balanced by diaphragm actions. I formulated 2D structural analysis models by inhouse software Oasys-GSA to check the deflection of proposed cut-and-cover box due to surcharge. Soil and Rock Springs were calculated and applied to the models based on the geological profile and Geoguide 1. I learned the general process and relevant requirements of structure stability assessment.

4.1.2 Slab, Beam and Column Analysis and Design

I was responsible for reinforced concrete analysis of slabs, beams and columns for the  proposed Cut-and-cover Box. Load combinations based on Hong Kong Code of Practice for Structural Use of Concrete 2004 were adopted. I considered loadings from both construction and permanent phases in the analysis and carried out the design under Ultimate Limit State and Serviceability Limit State. I gained substantial experience in design of reinforced concrete structures and appreciated the importance of considering loadings from construction  phase in the structure structu re analysis.

4.1.3 RC Wall Analysis and Design

In-situ RC walls were proposed under the diaphragm walls as retaining structures for Cutand-cover Box embedded in rock. To allow for vertical inclination of diaphragm wall during construction, I assumed thinner sections in analysis and design to ensure adequate structural strength of the RC walls. I realized that construction sequence and workmanship should be well considered in order to deliver sound structural designs at the early stage of a project. 4.1.4 Preparation of Tender Drawings

I also prepared markups, coordinated with draughtsman team and checked reinforcement drawings as part of tender documents. Please refer to my Project Report for  more details of my involvement in this project. 4.2 Supplemental Agreement No. 1 to Agreement No. CE42/2000 (CE) South East Kowloon Development – Stage 2 Infrastructure at North Apron Area of Kai Tak Airport – Design and Construction Construction Client: Civil Engineering and Development Department, Hong Kong Government. Contract Sum: HK$268 million 

As part of infrastructure works at Kai Tak Development, Stage 2 Infrastructure Works at north apron mainly consists of a 680m long twin cell box culvert, a sewage pumping station, road works and utilities. My involvements in this project are illustrated in the following sections.

4.2.1 Sewage Pumping Station Analysis and Design

I evaluated the feasible structural schemes for the sewage pumping station by comparing their costs and construction time. Two way span of walls and raft footing were identified as the Mr.

 better options optio ns than conventional c onventional vertical cantilever canti lever walls and a nd mini-piles by structural analysis and cost comparison. In the detailed design stage, I established 3D structural model to assist with the structural analysis. I also learned the importance of adequate cover, concrete mix and control of crack width in the durability design of water retaining structures.

4.2.2 Twin Cell Box Culvert Analysis and Design

Differential settlement is critical to the proposed twin cell box culvert as the soil conditions varies along with its layout. I calculated soil springs based on SPT N-values as suggested by the Ground Investigation Report prepared by in-house geotechnical team. By adopting software Oasys-GSA, I simulated four sections of the box culvert to check its differential settlement under various soil spring values and considered both construction case and  permanent case in the analysis and design, and provided movement joints every 12 to 15 meters to cater for its movements. Coordination with geotechnical team expanded my views to the overall structural design process and increased my knowledge in geotechnical engineering.

4.2.3 Steel Frame Analysis and Design

A steel frame was proposed by the Architect to be connected to the pumping station as an open walkway. I simulated this steel frame with Oasys-GSA and considered load combinations according to the Code of Practice for the Structural Use of Steel 2005, including thermal load as the frame was subjected to direct sunlight.

4.2.3 Detailed Design of Drainage and Sewerage System

I was also responsible for design of drainage and sewerage system according to Drainage and Sewerage Impact Assessment Reports prepared in preliminary design stage. This further expanded my exposure to other design disciplines of civil engineering project.

4.2.4 Preparation of Design Reports, Tender and Contract Documents

In addition to carrying out the detailed structural and drainage design, my involvement also includes preparation of design reports, particular specifications, and tender/contract drawings. I also estimated the quantities of excavated soils, backfill, concrete and steel reinforcement to  be required for the preparation of bills of quantities. Through preparing the relevant Mr.

documents, I experienced the tendering process and learned the contract documents were the  basis of contract management man agement in construction constructi on stage.

4.2.5 Coordination with government departments and utility undertakings.

During the tender stage, I attended meetings with relevant government departments, including CEDD, DSD, LCSD, etc, and prepared meeting minutes. I also proposed utility layouts after coordination with relevant utility undertakings, including CLP, Towngas, PCCW, etc. My communication skills were substantially enhanced by intensive coordination and preparation of relevant correspondence.

Please refer to my Project Report for more details of my involvement in this project.

4.3 Proposed Tsz Shan Monastery Development Development at Ting Kok, Tai Po

Client: Cheung Kong (Holdings) Ltd. Contract Sum: HK$466 million  The proposed monastery is located at mountain area of Ting Kok, Hong Kong. A design team was established covering various engineering disciplines, including structure, E&M, geotechnical and civil. I acted as coordinator and designer of civil team for this project.

4.3.1 Preparation of Amendments for Building Department’s Approval

My responsibilities in this project were reviewing the overall drainage system based on actual site conditions, preparing BD amendments and obtaining BD’s approvals from time to time. From this I obtained experience in BD submission and amendment process, and relevant Building (Construction) Regulations on control of private buildings in Hong Kong.

4.3.2 Coordination with Clients, Architects and Contractor

As the coordinator of civil team, I attended various interface meetings with clients, architects, structure team, E&M team and the Contractor. With intensive briefings and discussions, I got a better understanding of the management process of private building projects in Hong Kong, and gained more confidence in dealing with challenging clients and architects.

5.1.1 Review of Material Submissions

Compliance to contract specifications and relevant standards is essential to control the quality of construction materials.  I reviewed the construction materials, including concrete, steel reinforcement, concrete pipes, etc, and checked their compliance to the requirements as specified in the Specifications in respect of their components, test results, QA certificates, relevant job reference, etc.

5.1.2 Review of Temporary Works and Method Statements

According to contract requirements, all the temporary works design and method statements for the works should be checked and endorsed by Independent Checking Engineer. I reviewed the endorsed temporary works design with care and checked if there was any deficiency. For instance, a 16m long strut was proposed as the main strut for the ELS works of sewage pumping station. However, I checked the temporary design and found the strut would fail in buckling without the intermediate support. I requested the contractor to  proposed alternative structure system and finally one king post was installed as support for this main strut.

From reviewing the various temporary works design and method statements, I obtained extensive knowledge in the structural steel design, construction method of temporary and  permanent structures. structur es.
