Safety Walk with Thomas

ᐅ The World-Class Kai Tak Sports Park Embraces Construction Digitalisation

The Kai Tak Sports Park is the most important investment in Hong Kong sports infrastructure in recent decades. Occupying 28 hectares of land, the Kai Tak Sports Park is about 47% larger than the Victoria Park and will become the largest sports infrastructure in Hong Kong. As a brand new and sports infrastructure, its construction methodology and safety standard are also leading the industry. Complexity and time-constraint are the tough challenges for the construction team. Nonetheless, the team strives to maintain good safety management and has adopted innovative technologies which effectively minimise work-at-height activities, enhance productivity and accuracy, and set a new benchmark in the construction industry. Last week, Ir Thomas HO, Chairman of CIC and Ir Albert CHENG, Executive Director of CIC, and Sr Thomas HO, Member of CIC visited the site of the Kai Tak Sports Park. The Hip Hing project team shared how they adopt innovative technology to enhance construction safety.

 

Leading Transformations through Collaboration

Kai Tak Sports Park comprises three large sports facilities, including: the “Main Stadium”, the “Indoor Sports Centre” and the “Public Sports Ground”. Bringing sports and leisure together. According to Mr. Eric Lau, Construction Project Director of Hip Hing Engineering Company Limited, the Sports Park adopted the model of “Design, Build and Operate”, under which the design team has been working closely with the construction and operation teams since the early stages of the project. Moreover, different teams also relocated their bases to the site office at the Sports Park, to perform their roles in a timely manner with respect to various construction designs and transform different ideas into reality.

Besides the design, construction and operation team, the project also involves many other contractors in building services, structural steelworks, external facades of buildings and retractable roof construction. Therefore, extensive use of Building Information Modelling (BIM), Design for Manufacture and Assembly (DfMA) and Multi-trade integrated Mechanical, Electrical and Plumbing (MiMEP) techniques has been using in this project to increase the efficiency of design and production, as well as enhancing the construction safety and risk management. The construction team fully utilises BIM for the preparation works of construction, allowing them to identify conflicts and figure out solutions in advance and proceed the construction safely and smoothly. Once the designs are ready, different prefabricated parts will be produced overseas factories for simultaneous prefabrication and the completed assemblies will be delivered to the site and finally handed over to operation team. This does not only greatly reduce the construction period, but also reduces the manpower and helps to create a safer working environment for frontline workers. This project fully illustrates how technology brings positive change to the site, and was awarded the “2020 BIM Achievement Award'' by the Council.

Mr. CHU Tat-chi, Managing Director of Hip Hing Construction, pointed out that the “Design, Build and Operate” model enabled them to plan the construction and operation arrangement at one go. They also had ample time and space to complete the works which made the project more cost-effective, boosting the efficiency and productivity of the project.

 

Sharpening tools for the tasks ahead

The retractable roof is one of the special features of the Main Stadium of Kai Tak Sports Park. Its roof is mainly supported by four sets of main steel trusses with a span of 180 m maximum and such scale is considered to be a mega building project in Hong Kong. The main steel truss consists of large steel circular hollow sections, with the diameter of the largest section being up to 1.6 m. Making use of computer-controlled welding machines for welding, the construction team also adopts advanced technologies such as BIM and DfMA in the prefabrication process, so as to improve quality and speed up the construction progress in terms of the on-site construction, the team also makes use of BIM for better visualising the design and facilitating the overall enhancement and construction processes. By transforming all the prefabricated components into “exploded-view drawing”, this illustrates the different functions of the components and the design for assembly in a three-dimensional way, so that contractor clearly understands the steps and methodology of installation for each procedure, e.g. external façade installation, building services installation and retractable roof construction, etc.

The Main Stadium of the Kai Tak Sports Park will accommodate 50,000 spectators and the steel structure of the roof involves 13,600 tons of structural steel. This, coupled with the area needed for the cranes, the storage of materials and the assembly of prefabricated components, requires a significant amount of space. Therefore, the team builds a travelling gantry, for the installation of around 1,700 prefabricated units for the upper rows of seats. All these are completed with the aim of design for safety, productivity and sustainability, minimising work-at-height and crossing operations in mind.

 

A step towards “paperless site environment” through the use of advanced technologies

In order for frontline workers to have a clear understanding of how to bring innovative technologies into construction sites, the project team makes use of a platform called “Dalux” which not only facilitates the planning and execution of BIM tasks, but also allows site personnel to go into the site without the need to bring along the drawings. The GPS tracking function allows personnel to have a clear understanding of the project and tasks’ progress in real time, while also keeps information constantly updated through the use of cloud technology. The whole team therefore simultaneously monitors the progress and minimises mistakes. Hip Hing’s professional team once again demonstrates the industry’s continuous pursue of excellence and the spirit of “Life First” and “Zero Accident” with concerted efforts.

ᐅ Carbon Neutrality Journey - CIC-ZCP x iHub: Showcase Construction Infinity

As climate tipping points lie alarmingly close, achieving carbon neutrality is the task in hand. The construction industry consumes approximately 36% of all energy consumed globally and accounted for 40% of all carbon emissions in the world. In order to achieve sustainable development, the Construction Industry Council is determined to lead the industry towards the goal of carbon neutrality.

 

Leading Low Carbon Construction Technology Showcase

Ir Thomas HO, Chairman of the CIC, visited the CIC–Zero Carbon Park (CIC-ZCP) in Kowloon Bay in late April to learn about the latest development of this landmark facility. Established in 2012, CIC-ZCP serves as an exhibition, education and information centre to raise awareness of the importance of low-carbon living, showcasing the state-of-the-art eco-building design and technologies to the local and international construction industry, and eventually innovates the stakeholders to deploy new technologies as a way to reduce carbon footprints. 

Zero carbon building is a building that has zero net carbon emissions on an annual basis. CIC-ZCP aims to achieve this by generating on-site renewable energy from photovoltaic panels and a tri-generation system using biofuel made of waste cooking oil. On top of being self-sustainable, CIC-ZCP exports surplus energy to offset embodied carbon of its construction process. Apart from renewable energy generation, CIC-ZCP has taken various passive design measures to save energy. For example, CIC-ZCP is cross-ventilated as its main facade faces southeast to take advantage of the prevailing summer breezes coming from that direction. The elongated form of CIC-ZCP also enables a suitable room depth between the northwest and southeast facade for daylighting.

 

Upgrade and Update

CIC-ZCP has never stopped upgrading throughout the decade. Chairman of Zero Carbon Building Management Board, Mr CHONG Kin-lit, Paul explained that the park has installed the “Air Improvement Photovoltaic (AIPV) Glass Canopy” to replace the old canopy of the cafeteria in CIC-ZCP. The glass canopy not only offers daylighting, on one hand it generates renewable energy from sunlight through cadmium telluride nano thin-film photovoltaic technology. On the other hand, the quantum dot nano top coating system decomposes PM2.5 and volatile organic compounds, which will help improve air quality. Ir Thomas HO appreciated the efforts CIC-ZCP has paid to put new technologies into practice for the benefit of the members of the public.

 

A pioneer of MiC

To achieve the target of carbon neutrality, the construction industry should stay up to date on the advancement of technology. CIC-ZCP together with the “MiC Resources Centre”, “Building Information Modeling Space” (BIM Space) and the “Construction Innovation and Technology Application Centre” (CITAC) have formed the "iHub”. The brand new “i-Hub” exhibits advanced technologies and materials to promote the application of innovative techniques and solutions in the local construction industry. While the “Modular Integrated Construction” (MiC) approach is widely adopted nowadays, this method was once doubted when introduced to Hong Kong several years ago. Back in 2018, CIC pioneered the development of MiC by constructing Hong Kong’s first MiC-constructed building in CIC-ZCP, giving a lead to the industry that this “factory assembly followed by on-site installation” method is favourable to improving construction productivity, safety and sustainability. There are more than 60 local construction projects adopting MiC so far, including the Temporary Quarantine Camps built in Lei Yue Mun Park and Penny’s Bay.

 

Education is key to carbon neutrality

Carbon neutrality can only be achieved when members of the public work hand-in-hand, CIC-ZCP aims to serve beyond the industry, and into the community. The CIC-ZCP’s Sustainable Development Exhibition showcases the blueprint and key elements of sustainable city development. Through a series of interactive fun-packed games, guided tours, educational workshops and "ZCP Green Heroes" Award Badges Programme, CIC-ZCP encourages students to participate in various carbon reduction activities, hence understanding the importance of sustainable development and carbon neutrality. With nearly 200,000 traffic recorded last year, Mr. Paul CHONG envisions CIC-ZCP to become a spark of sustainable development, and eventually foster the public to live a low-carbon lifestyle.

 

Lungs of the City

Sustainable development should not be confined to technological breakthroughs and protecting the environment, a healthy lifestyle is also essential. CIC-ZCP is home to over 200 species of flora, attracting numerous types of birds. With rich and varied biodiversity, CIC-ZCP functions as the “lungs of the city”, and this urban forest offers a relaxing space to the community.

CIC-ZCP dedicates to shoulder the social responsibility for promoting the sustainability and infinite construction possibilities. CIC-ZCP has attracted over thousands secondary and primary school students every year, and it is the popular picnic and recreational hotspot. According to the third-party statistics, the media values of CIC-ZCP has exceeded HK$30M recent years.

Leading forward, CIC-ZCP will continue to act as a test bed for new energy and advanced technologies, shoulder the responsibility of promoting low-carbon living and green-building design, and lead the industry and the public towards carbon neutrality.

ᐅ The Hong Kong Institute of Construction Held a Moment of Silence to Raise Safety Awareness

Zero tolerance to accidents! To promote safety awareness in the industry, especially among frontline construction practitioners, the Construction Industry Council (CIC) encourages the industry to organise regular Silent Tribute events for conveying safety messages to management staff and workers and encourage them to learn from unfortunate experiences. The Hong Kong Institute of Construction (HKIC) under CIC holds Silent Tribute events regularly where instructors and students held a moment of silence for workers who lost their lives in accidents. To make sure that students understand the importance of safety, we included analysis of potential causes of accidents as a key element in the event.

 

Industry to hold Silent Tribute events to promote caring culture

To achieve excellence, not only project quality has to be guaranteed, construction companies should also ensure construction safety at sites. As the industry’s pioneer, CIC encourages the development of a caring culture in the industry, the Silent Tribute event will set a good example for the industry and is well received by industry leaders. Ir Thomas HO, the Chairman of the CIC, Ir KAN Jun, Council Member of CIC and Mr. CHAN Lok-chai, President of Registered Specialist Trade Contractors Federation joined the Silent Tribute in early April and shared some sincere remarks on safety issues with students from the foreman course.

 

Between January to March this year, three fatal accidents likely to be related to fall from heights and trapped in or between objects occurred, all are very unfortunate. HKIC instructors briefed students on the incident summary and analyze potential causes to the accidents. Reflection was made on how to avoid accidents, for example, did workers check if there is any suitable protective barrier? Is independent lifeline with fall-arresting devices available? Did frontline management brief or give instruction before commencement of work?

 

No heroes needed in safety

Ir Thomas HO warned students, “Some workers think their experience overrides safety precautions, and tragedies happen. Students will become foremen after graduation, you must bear in mind that workers need to know the risk before they start working, and it will save their lives.” He also reminds students that immediately stoppage is needed if work sequence is different from the planned sequence suddenly. Life will be protected if we stay alert and take one extra step.  

Look before you leap

It is important to look before you leap, especially at construction sites. CIC remind the industry regularly that decisions made controls workers’ lives and their family. Ir KAN Jun shared that “You must make safety a habit because it will affect more than one family. I know that many accidents are caused by improper use of safety belt, it is important to stay alert. PPE is just the beginning of safety measures, workers with less experience may be less aware of safety hazards, so regular training is needed.”

 

Everyone is responsible for Construction Safety

Mr. CHAN Lok-chai visits sites frequently, he pointed out that “Foreman is an important role with great responsibilities because they are the ones who should know all happenings on site, such as how to perform lifting operations safely? Did workers let the form work finish in a safe environment for next sequence?” He also encouraged owners, main contractors and sub-contractors to organise mandatory talks for workers and learn from the bitter experience of families who have lost their loved ones.

 

Guideline for the Industry

With the “Zero Accident” principle, through Silent Tribute events, CIC and HKIC strives to promote safety awareness and understanding of safety standard and deliver the message clearly to construction workers. CIC has prepared a guideline with recommended rundown for the industry for organising Silent Tribute events. Owners, main contractors and sub-contractors are encouraged to hold a moment of silence for workers passed away in accidents on their own but it should carry the most important message in the event which is “Safety Assurance” and potential risks could be avoided.

 

CIC reviews and monitors safety performance in the industry from time to time while joining hands with the industry to foster a positive safety culture. CIC and the government strongly encourage sites to arrange workers to do warm-up exercise “Baduanjin” before the commencement of the work daily. Exercising can enhance workers’ physical flexibility and encourage a healthy lifestyle to minimise the risk of injuries. It is helpful to workers’ health and prepare them for the long day of work ahead. Therefore we strongly encourage to include “Baduanjin” in every Silent Tribute event. HKIC organizes various training courses on construction safety for workers to promote safety awareness and attitude. Eventually, we hope to foster the concept of “Life First” in the industry on all fronts. Let’s say “No” to Danger together!

 

ᐅ "Safety First" Supported by Technology at Lyric Theatre Complex Site

 

Construction safety has always been the Construction Industry Council (CIC)'s top priority in our work in promoting industry development. Unfortunately, there was another fatal accident during the past Easter holiday where a cleaning worker fell from height. In fact, every aspect of a construction project, including process design, site management, application of technology, and training are essential to construction safety, and every detail can give better protection to workers.

 

Innovative technology adoption from design to execution

Last week, Ir Thomas HO, Chairman of CIC, and Ir Albert CHENG , Executive Director of CIC, visited the site of the Lyric Theatre Complex at West Kowloon and extensive adoption of BIM, MiMEP and MiC method were demonstrated. Contractor's planning and intelligence in minimising potential risks can be seen from the project's process design to technology application. It is a exemplary reference for the industry. Mr. SM LIN, General Manager, Construction Projects of West Kowloon Cultural District Authority explained that the extensive use of BIM enables constant checks on construction accuracy which helps to ensure construction safety. This project is a fusion of architecture, technology and art and sets a good example for fellow construction project owners.

The Lyric Theatre Complex in West Kowloon has an atypical outlook. The irregular shape of the building brings complexity and uncertainty to its construction process. With an aim to simplify on-site construction procedures and processes, the contractor adopted BIM extensively to achieve "Design for Safety". Much effort has been put into the initial design stage to achieve construction safety and reduce potential risks. With BIM in place, calculation and Parametric Design can help reduce the number of curved panels used for the curvy facade from more than 300 pieces to approximately 160 pieces . The steel internal support structure can also be modularised. With the help of technology, we believe modularisation of curtain walls and even modularisation of interiors can be made possible and will bring about further improvements in construction productivity.

 

Minimising risk with Internet-based Dynamic Risks Assessment

With careful planning during the design stage, uncertainties and unknown risks can be greatly reduced as "how" and "when" are well-determined throughout the construction process. We can also benefit from the detailed planning as everyone will be well-informed of accurate and useful information of the project, as detailed as the position of every screw. The developer, the consultant, the contractor, the technical team or even the workers will be able to perform their duties in a safe and organised manner. Contractor can suspend the work and install safety equipment instantly with the internet-based Dynamic Risks Assessment and resume construction in a safe condition when all workers are informed of the changes.

 

 

Implementation of the DfMA concept

Actual architectural consideration will follow when an effective and disciplined design is in place. Mr. Iain Hubert, Project Director of Gammon Construction, introduced at the Lyric Theatre Complex site that nearly 70% of the building process of the site's engine room and large-scale plumbing installations were built with DfMA and MiMEP method. Parts were pre-fabricated in the factory to ensure their quality and DfMA can greatly reduce welding works and works at height on site. Onsite procedures can be reduced from 40 to 10. These design ideas have greatly reduced the potential risks on site. The team also enjoyed the much shorter procedure as minimal installation work is needed at site likes fixing hoses and screws were completed in just 24 working days, an outstanding achievement in construction safety and efficiency!

Prefabricated construction can reduce on site manpower requirement and it is particularly important during the pandemic. During the outbreak of the fifth wave of the epidemic in Hong Kong, many workers were unable to go to work and logistics between Hong Kong and the Mainland was hindered, which also affected the delivery of materials and in turns, the progress of construction projects. Yet with the adoption of DfMA, components can still be manufactured in the mainland which shortens the onsite construction time and ensures a smooth construction progress. Mr. Sunny CHAN, Chief Projects Officer of the West Kowloon Cultural District Authority, mentioned that part of the site was reserved for workshops and local pre-fabrication so as to avoid delays in construction progress caused by logistics problems during the pandemic.

 

Quality and logistic monitoring in the Digital Control Centre

The digital control center in the construction site is indispensable to maximize the benefits of the technology application on the construction site. The MMC (Modern Method of Construction) system is a consolidation of various technologies. Since the start of the design works of the Lyric Theatre Complex with BIM, through the construction process with MiMEP and DfMA construction work, all data are recorded in the system with the help of Internet of Things (IoT). The team in charge of managing the MMC system are in control of all processes, and will be able to monitor the project quality on the digital platform, components arrival time and even the person receiving the components and ensure that the entire project runs smoothly. An AI-powered CCTV is also included in the system to ensure workers are wearing their hard hats and masks properly and will issue instant warnings to secure the implementation of safety instructions. If all engineering projects adopt such system, all the data can be consolidated to achieve standardisation in construction sites, which will improve the time, cost, quality, safety and sustainable development of projects.

Construction safety is indeed a responsibility for all and everyone should contribute. In order to encourage frontline colleagues' commitment, the Council awarded two outstanding engineering colleagues with tablet computers - Victor, who is committed to create a safe working environment by integrating BIM, MiMEP, MiC, etc.; and Herman, who inspects the construction site and reminds subcontractors and frontline workers to pay attention to safety at work. CIC looks forward to more integration of safety details into construction process and "Life First" is always the industry's first priority!

 

ᐅ Building Home for the Elderly With Young And Innovative Power

 

Achieving “Zero Accident” is the top priority on construction sites. By adopting the concept of “factory assembly followed by on-site installation”, Modular Integrated Construction (MiC) helps to ease and solve some of the safety challenges faced by the industry.

 

Life First

CIC strives to raise safety awareness and safety standards in the construction industry. It is believed that every industry stakeholder has a role to play in building a strong safety culture. Last week, Ir Thomas HO, Chairman of CIC and Ir Albert CHENG, Executive Director of CIC visited the site of the Purpose-built Multi-welfare Services Complex in Area 29 of Kwu Tung North Development Area. Construction team from Shui On Construction and Materials Limited (SOCAM) demonstrated the use of robots and innovative technologies including Automated Material Delivery Robot with a Web-based control system and an Anti-Collision system. Such technology is designed for efficiently uplifting productivity, build quality, site safety and environmental performance of the whole project. Freddy Lee, Chief Executive Officer of SOCAM shared his experience of working with young colleagues and how the company supported them to generate more innovative and interesting ideas for construction projects.

 

 

Creating Miracles

In this 8-storey building, approximately 42% of total construction floor area is built using the revolutionary MiC technology to house 7 residential care homes for the elderly to provide 252 beds. With this method, free-standing integrated modules (completed with finishes, fixtures and fittings) are manufactured and assembled in a factory. By transferring on-site construction processes to a controlled factory environment, buildings can be substantially completed off-site.

It perfectly echoes with the miraculous Community Isolation Facilities which were built within two months and are currently providing 20,000 isolation units. Not to mention that Tsing Yi community isolation facility was completed in only seven days. Thanks to MiC technology, the “plug and play” facilities were handed over smoothly in such a short time and of outstanding quality.  

 

Plug and Play!

Prefabricated construction technology never ceases to amaze us! As the first project with full MiC application and green construction by SOCAM, this Multi-welfare Services Complex sets a new standard to elderly home projects while proving how prefabricated building method can get work done faster, at lower cost and most importantly, in a safer environment. We look forward to seeing its completion in late August this year, and more elderly people can live in better home to enjoy the care provided to them.
