Project Title: Construction of [name] underground street in [location]

Position and Project Brief: Engineer in charge of Mechanical Ventilation System Design for the [/] m-long underground street serving [n] population.

Professional Experiences

I was the Engineer in charge of the Mechanical Ventilation System Design for the [/] m-long underground street in [location] serving [n] population. This Mechanical Ventilation System was designed to provide air ventilation and smoke extraction for the Underground Street. This Mechanical Engineering Ventilation design was complex as the underground street was developed in several phases. Additional consideration was given to the life-time performance and the interfacing issues during the interim stages.

I firstly prepared the design for smoke extraction and proposed a layout with [n] fans distributed in [n] ductworks to meet the requirement in the Fire Engineering Report. I determined the fan capacity and the minimum smoke extraction rate for this system to ensure that each smoke zone could extract smoke at [/] m³/s with a make-up air velocity lower than [/] m/s. This design also could meet the requirement stipulated in Building Department Fire Safety Code, the smoke extraction requirement in the Fire Services Department Code of Practice for Minimum Fire Service Installations, the air quality requirement in associated with Environmental Impact Assessment (EIA) Report, etc. Then, I applied the Darcy Weisbach equation to determine the pressure loss due to friction along the ductwork and tunnel. I also determined the pressure loss through various fittings and equipment of the Mechanical Ventilation System. This Mechanical Ventilation System design was accepted by the client.

Maintain Engineering Knowledge

I joined and attended seminars, factory visits, group discussions organized by the HKIE, the Institution of Mechanical Engineers (IMechE), etc. to upkeep my technical knowledge, project management skills, etc. Through direct discussion with experts in different fields, I obtained the up-to-date technical knowledge of building services engineering industry.

Moreover, I obtained in-depth knowledge of the structure and working principles, design code, etc. through my professional experiences on projects. I also developed my knowledge of material science related to design of the Heating, Ventilation, and Air Conditioning (HVAC) and drainage system etc.

Project Title: Construction of [system name] in [location]

Position: Engineer in charge to prepare the HVAC system design

Project Brief: Drainage system for [project name] project with total area [area]m² in [location] serving [n] population.

(Consultant Fee: HKD [cost]M or Construction Cost: HKD [cost]M)

Professional Experiences

I was the Engineer in charge of the drainage system design for the [project name] with a total area of [area]m² in [location] serving [n] population.

The drainage system design was complex as the project involved a large roof surface area (i.e. [area] m²) which made it difficult to fulfill the statutory requirement stipulated in Cap123i Building Regulation and client’s expectations. To resolve this engineering problem, I applied the Manning Equation to determine the pipework dimension for a conventional gravity system with a 3 m/s flow velocity, which would be [length]mm. The [length]mm drainage pipes were too large and not acceptable by the client.

Hence, I recommended using a siphonic rainwater system to balance the diverse needs. I prepared the pipework layout of this siphonic rainwater system and then carried out the hydraulic calculation by applying the Darcy Weisbach equation. I found out that using siphonic rainwater system could reduce the pipe size and fall gradient with [n] times better performance. My proposal to use a siphonic rainwater system was accepted by the client and approved by the Building Department.

Project Title: Upgrading of HVAC system for [name] Building

Position and Project Brief: Project engineer to manage and supervise the construction activities associated with the upgrading of HVAC system for [name] Building

(Consultant Fee: HKD [cost]M or Construction Cost: HKD [cost]M)

Professional Experiences

When I seconded to a mechanical sub-contractor company, I was the project engineer responsible for managing the upgrading of HVAC system for [name] Building. I managed the budget plan, project programme, manpower arrangement, etc. I adopted “MS Project” to identify the critical paths of different construction activities, e.g. submission date, ordering, delivery, Testing and Commissioning (T&C), etc. For the budget plan, I carefully reviewed the quotations of different mechanical equipment and chose the mechanical equipment with acceptable quality and a competitive price. Besides, when I planned for the manpower arrangement, I estimated the required man-hours of the key tasks with the aid of records of previous completed projects to ensure that my manpower arrangement was feasible and the works could be completed in a timely manner.

In the detailed design stage, I conducted risk assessments and managed the risk associated with the implementation of upgrading the HVAC system with careful consideration of opportunities and consequences of potential incidents according to designed piping systems, possible installation sequence, and method of equipment and pipework.
