The ceiling maintenance project for Hong Kong Coliseum
The ceiling scaffold in the Hong Kong Coliseum was built by extending from the metallic pipelines under the ceiling. The scaffold was hanged in the air by wire connecting to the metallic pipelines. The first bamboo was started from the highest point of the auditorium which was also the nearest to the ceiling. This scaffold was double-layered, with thicker bamboos used for the lower layer and thinner bamboos for the upper layer. The lower layer was for maintaining illumination and acoustic facilities and the upper layer was for maintaining air-conditioning facilities. The whole scaffold was composed of 4 sections, with each being built from 4 different corners toward the middle.
A scaffolding built on open area
This scaffold was built in an open area at the TVB’s Tseung Kwan O TV city. It had nothing to lean on. To give stability to this scaffold, a broad base was required. It is usually built in such a way that the base has the same breadth and height so as to secure the most stability.
A scaffold retaining the harbour view
A scaffold was built at a restaurant at Hong Kong Cultural Centre to fix the problem of water leakage on the glass wall. To make the harbour view from this glass wall accessible to the customers, the scaffold was not covered with a protective net, which was a rare practice in the industry.
A double scaffold along a narrow lane
It was a double scaffold at the Lung Sum Avenue Indoor Recreation Centre, Sheung Shui.
A scaffold at a bus stop
The point of balance of this scaffold is in the middle. The work usually starts in the middle point and extends to the two opposite directions. The work platform is 2-3 feet high from the ground. This scaffold is mainly supported by two bamboos: one being set vertically upward and the other vertically downward.
A combined scaffold to renovate the flyover
It is a combined scaffold at Mau Yip Road, Tseung Kwan O. It has a work platform on the side of the flyover and a ceiling scaffold at the bottom. The two bamboos extending upward and downward respectively at an inclined slope of 45 degrees, supporting the whole scaffold structure.
Multiple work platforms
This scaffold with multiple work platforms was located at the Hong Kong Science Museum for the renovation of the rooftop. Each platform was 2 metres apart and was built at a position where work was to be done.
A hanging scaffold for building a ventilation pipe
The Kiangsu- Chekiang College, North Point planned to build a ventilation pipe for the laboratory. A hanging scaffold was built for such construction.
A hanging scaffold for replacing glass windows
The hanging scaffold was built for the maintenance of the Queen Elizabeth Stadium, Wanchai. To build a hanging scaffold, there were tripods of 2 metres apart. Bamboos were laid on these tripods to form into a work platform. Around the platform, bamboos were set at vertical and horizontal directions forming into a scaffold.
A hanging scaffold with a zigzag shape
Hanging scaffolds can be flexible to fit with the spatial feature of a building. These can also be of multiple levels from the bottom to the top. A number of hanging scaffolds were built on the exterior wall of the Grand Marine Industrial Building in Aberdeen. The hanging scaffold with a zigzag shape was built at the Queen Elizabeth Stadium, Wanchai.
A hanging scaffold on the ceiling
The hanging scaffold was built at the Swire Coco Cola Ltd, Shatin to enable the installation of fire hoses at the ceiling of its car park. Below this scaffold cars continued to pass through. Installation work was actually implemented at night time.
A mini ceiling scaffold
The mini ceiling scaffold was built at the car park of Chun Shek Estate, Shatin. It was originally built from the ground level up to the higher levels.
A ceiling scaffold supported by a number of single scaffolds
The ceiling scaffold was built for the maintenance of the playground in Ping Shek Estate. Each single scaffold was 3 metres apart.
A work platform covered by canvas
The photo was taken at the ceiling level. This scaffold was built for the maintenance of the indoor sports ground of Tseung Kwan O Recreation Centre. The project was to replace the light bulbs with energy saving ones. The scaffold covered by canvas was necessary to protect the delicate bulbs.
A ceiling scaffold on the top of a building
A ceiling scaffold was built on the top of a construction site at the Kwai Chung Crematorium. The purpose was to add more levels to the building.
A protective scaffold for passers-by
This protective scaffold was built at Yuen Long Police Quarters for married employees. The purpose was to cover the sidewalks in case of small rocks and other debris falling from above causing injury to the passers-by. On top of this scaffold was a net and canvas. This scaffold was made up of a single scaffold and a ceiling scaffold. The ceiling scaffold was inclined to a degree to prevent accumulation of rain water.
A protective scaffold under a hanging work platform
This protective scaffold was built at City One, Shatin to prevent accidents caused by falling debris from happening.
A protective scaffold for the safety of the third person
This protective scaffold was built at the entrance of a car park in Shouson Hill. Above the car park, there was a wall painting project going on. In recent years, a protective scaffold has appeared to be necessary in construction sites as the society has become more aware of the danger of construction that might cause to its neighbourhood.
Two inclined scaffolds
Inclined scaffolds are found in most renovation projects. This is an additional protective layer built on top of a vertical scaffold, to prevent small things from the above hitting the passers-by. This inclined scaffold at the middle of the high-rise structure was called inclined shelter or safety scaffold. According to the law, for every 18 metres in height, an inclined scaffold has to be built, which should be 2 to 2.5 metres away from the building’s exterior wall. One scaffold was built at Ebenezer School & Home for the visually impaired and another one at Mongkok Police Station.
A bamboo pier for dragon boat athletes
The bamboo pier was at the Shing Mun River, Shatin. It was a project commissioned by the Dragon Boat Association who needed a temporary pier for the athletes to get on the dragon boats. The platform was built by wooden planks and was used for 2 days only.
A hemispheric scaffold at Hong Kong Space Museum
This was a special and unique scaffold for the Hong Kong Space Museum. This hemispheric scaffold was a structure of inclined, double-layered scaffold with work platforms. The double layers of the scaffold were fixed to each other. The scaffold was built spirally without the use of a single screw nor an iron nail. The work process was tedious but not difficult. It was built for a renovation project to prevent water leakage at the Hong Kong Space Museum in Tsim Sha Tsui.
A scaffold on the highway road sign
This scaffold was on the highway on Castle Peak Road leading to Lantau Island. One of the driveways was closed for this construction. The problem of building scaffolds on the highway was that workers had to work under strong wind. They had to handle the bamboos with great caution, preventing bamboos from falling onto the ground.
A scaffold for the opening ceremony at a temple in Tai Po
The scaffolds were built to hold the flowers banners. Single scaffolds were sufficient for this purpose. The problem here was to find a stable support for holding the scaffolds because it was an open space area without anything to lean on. Workers usually fixed water pipes and iron rods into the soil as supports.
A ceiling scaffold on the water proof rooftop
This scaffold was built on the water proof rooftop of Shun Lee Estate Shopping Centre. A critical requirement was to protect the water proof material while setting up the scaffold. What the workers did was to place two horizontal bamboos on the ground of the rooftop and fixed vertical bamboos against the two horizontal ones without scratching the water proof material on the ground.
A temporary bridge made of bamboo
This bridge at the Tai Lam Correctional Institution was built by workers who stood on a boat. The workers inserted China firs vertically into the water forming the foundation of the bridge. The bamboos were fixed along a line so that they became the frame of a bridge. This bridge was built in 2 days and used for 10 days. It showed the advantages of scaffolding: quick, temporary and convenient.
An “unprofessional” scaffold for a Chinese opera
This scaffold was built for the Chinese opera at an opening ceremony of a temple in Suen Wan, Tai Po. At the entrance of the scaffold, 2 supporting bamboos were selected from thicker bamboos and China fir. The sides and the top of the scaffold were covered by zinc plates, while the platform was covered by bamboos and carpets. Mr Chan did not consider himself an expert in this kind of scaffold, because he thought a scaffold of this kind should be more refined and beautifully crafted.
A rain water scaffold
Scaffolds usually do not have a top, but this specially designed scaffold had a top covered by canvas. It was particularly needed in the raining season. The scaffold in the photo was built to protect the installation of electrical escalator at Tai Po Complex. The canvas top was used to protect the welders from getting wet.
