There are many tradies carrying their works concurrently on the same floor. This attributes to the compressed cycling of the typical floors construction. Missing either of the trades would break the cycle and results in delay. If you have issue to understand , feel free to drop us enquiry
Olympic Villages have accompanied Olympic Games since the Olympics in Los Angeles, 1932. The Village designed for the Helsinki Games in 1952 was the first intended to be converted into housing. Now, following Helsinki’s example, Olympic Villages are often converted into residential units, with rare anomalies such as Lake Placid 1980, which now stands as a federal prison. However, the success of each Village in their subsequent uses still vary immensely, depending on many interconnected factors such as sustainability and economic growth.
The Tokyo 2020 Olympics Village is set to be converted into a 13.9 hectare residential sub-division, ‘Harumi Flag’, by ten large developers, including prominent companies like Nomura Real Estate and Mitusi Fudosan Residential. Plans anticipate that the development, located in the centre of Tokyo on man-made island Harumi, would consist of over 23 residential buildings and a commercial facility, as well as other leisure and social services, such as parks and childcare facilities.

Whether or not these flats remain vacant in 2024, which is when the flats are set to be completed, cannot be determined for sure at this point. Despite this, after taking a look at the Sydney (2000), Athens (2004), Beijing (2008), London (2012) and Rio de Janeiro (2016) Olympic Villages it can be seen that there are a few common criteria that distinguish the successes from the failures. These include the economic state of the host country, whether private or public developers are in charge, how much emphasis is placed on sustainability and the amount of careful planning involved. The location of said Villages can also be taken into account, however this point may be secondary to the rest as it can be argued that with good planning and a decent transport system, such as will be seen in the case of London, distance from the city centre is not as significant a factor. When the pattern that successful Olympic Villages have followed is identified and compared with the journey of the Tokyo Olympic Village so far according to the criteria listed above, the future of the Village seems optimistic.
The Sydney Olympic Village was a remarkable success. Built in Newington (inner-west Sydney) and developed by a public-private partnership, it was a major stepping stone in terms of sustainability, and reportedly ‘changed urban planning and design in Australia forever’, in particular the development of greenfield sites. Unlike previous Villages, it was designed as permanent housing, and ‘used the principles of permanent dwellings that had game overlays to deliver the beds required for athletes’. For example, demountables that could be easily removed were placed in backyards and removed after the Games.

Rooms were also big enough for divisions to be placed inside. This meant that their target market – Sydney’s middle class , or even the general public, would be more willing to put their money forward and purchase housing as these residences were built more like a permanent home to live in rather than for a two-week temporary stay.

Furthermore, the emphasis placed on sustainability during its construction, with the area being the largest solar-powered suburb in the world, boosted the its status and bolstered its image, adding onto the pre-existing attraction of it being a former athlete’s village. Another factor that contributed to its success was the real estate boom and overall favourable growth in the economy at the time, which eliminated the risk of being unable to finance construction due to sudden large falls in consumer confidence and subsequently consumption. It meant that consumers were more eager to purchase new housing and so demand was able to meet supply more easily.
The Athens Olympic Village (2004) was to be turned into the ‘biggest social housing development in Greek history’ and was constructed on brownfield (‘degraded, polluted, minimally inhabited wasteland on the city’s far northern outskirts) land. It was a huge failure, with many flats now vacant and the infrastructure dilapidated. Its use as public housing, distributed to citizens through a lottery, diverged from the Olympic Village in Sydney, which was built to be sold as housing for those in the middle-class. Another aspect that differed from the successful Sydney Olympic Village was that it was built using ‘old, environmentally unfriendly technology’. Furthermore, even as the athletes were moving into the village, there was already criticism surrounding the living conditions, with some citing bad security and the housing being unfinished.
source:https://placesjournal.org/assets/legacy/media/slideshows/gade-olympic-villages-19.jpg
One core reason that it failed was that the costs for the event were underestimated due to a lack of careful planning and excessive extravagance. Greece simply could not afford the Olympics. The municipalities responsible for developing the area did not have the funds to sustain redevelopment and so the planned infrastructure and schools were never constructed, which inevitably withdrew from the value of the area. Another important factor to consider is the prolonged economic recession that Greece fell into later on, which the Games undoubtedly contributed towards. The following recession and debt crisis even more so meant that there were not enough funds to pay for the development. The lack of private sector involvement should also be taken into account – with Jay Scherer citing the Village as a ‘sobering portrait of the level of debt that can be accrued by the state in the absence of private investment in these developments’. There was also a lack of deliberation in terms of ‘environmental strategy and forward thinking’, or ‘economic feasibility studies or even a basic business plan’ as planners rushed to finish venues, leading to the soaring costs of the Games (cost nearly $11bn and double the initial budget), leaving diminishing funds behind to actually redevelop and maintain these venues.
Less is known about the reality of the Beijing Olympic Village (2008) now, but it was developed into housing for upper-class Beijing residents and has gravitated towards Newington, rather than Athens’ example. Environmentally-friendly amenities were also included, with the Village being equipped with geothermal energy and solar panels and a micro-energy building, and reportedly, the city ‘tied its Olympic agenda to long-term land use development goals’. This increased the appeal of the units, which would have led to a rise in demand for them. According to China Daily, even people from outside Beijing expressed interest in the condos after the Olympics. Ge Huai’en, the Village’s marketing director, also stated that ‘about 70% of the apartments in the Olympic Village in northern Beijing had been sold before the Olympics’. The price of these flats practically doubled in a year and a half following their market release and surrounding real estate values rose.

The London Olympic Village, now converted into a neighbourhood north of Stratford town centre known as East Village, was developed on brownfield land, following the example of the 1992 Barcelona Games. Forbes has labelled East Village (and Olympic Park) as a ‘rip-roaring success’, and Ben O’Rourke claims that the London Olympics’ real-estate legacy is largely responsible for ‘London moving east’. Of the 2,818 new residences created, 1,379 were labelled as affordable homes and sold to Triathlon Homes. The remaining private homes, plots for a potentially 2,000 more residences and long-term management of East Village are managed by Get Living London and owned by Delancey/Qatari Diar. Now, East Village is labelled ‘London’s Hippest Postcode’, with its architecture looking to ‘emulate the much-loved planning of Maida Vale and other parts of Victorian west London’ and is a ‘rare example’ of a housing devlopment that ‘shows more thought and quality than most things comparable built in Britain in recent decades’.
Source: https://inhabitgroup.com/project/east-village-london-e20/
East Village offers a variety of housing types, from apartments to townhouses and the neighbourhood also has facilities such as a school and health centre. Its transport links also serve as a major drawing point, for example, King’s Cross is fifteen minutes away, so despite its location, people are not overly deterred by that. The East Village’s success could be attributed to the dire need for affordable housing in London, especially following the Global Financial Crisis 2007-08. Overly high housing costs have long been an issue for Londoners, and naturally the housing in the East Village, part of which was marketed to be affordable, would have been in high demand and appealing to the public. The East Village was also designed with the environment in mind, with integrated transport, green open spaces (green roofs, wetland area, fruit trees etc.) and flats that adhere to a ‘high standard of energy-efficiency and insulation’. Long-term development was taken into account as well, with plans to have 24,000 new homes built in the area by 2031.
The Rio de Janeiro Olympic Village (2016) is, as Forbes describes it, a ‘ghost town’. It was built in the West Zone of Rio, in an upper-class neighbourhood. In a way, it was similar to Newington in that it was going to be developed as luxury housing, however the developer billionaire Carlos Carvalho seemed to lack an awareness of the true amount of demand for his luxury condos. He envisioned a ‘city of the elite, of good taste’ and that ‘for this reason, it needed to be noble housing, not housing for the poor’, with prices as high as $700,000. He may have had overly-ambitious prospects for the Village, which helped cause its current vacant state.
source:https://architectureofthegames.net/wp-content/uploads/2017/03/Rio-2016-Olympic-Village-Apartments-on-sale-in-June.jpg
The key difference here between Rio and success stories like Newington is the overall financial state of the host countries – Sydney’s economy was arguably more stable, and there was a larger demand for middle-class or luxury housing than in Rio, where there is an ever-widening gulf between the rich and poor. Had there been increased community consultation and a greater awareness of what Rio actually needed, instead of purely focusing on financial motivation, as Carvalho seemed to have done, the project may have been more successful. Another factor, as Isabel Swan states, ‘I feel the Olympic Games in Brazil were not so successful because the legacy was not the number one concern’. The economic downturn and large fiscal deficit in Brazil did not help matters, and only 240 of the 3,600 units had been sold two weeks before the opening ceremony of the Games. Even now, apparently 93% of the condos are vacant. Furthermore, the Village during the Games did not have particularly favourable reviews either, with Kitty Chiller, the Australian Olympics boss, claiming that the units were ‘unliveable’. There are notable similarities between Athens and Rio – poor economic state, poor governance and poor time management, with both countries’ venues being built in a rush.
The successful Olympic Villages have several factors in common. They tend to be built as residences to be sold to the middle to higher classes, and the environment is often a priority. The economy, in particular the real estate market of the host country, also tends to be stable. Furthermore, if the host country is developed, this improves its chances on developing the Village aptly as there is a larger probability that they would have the funds to sustain this, especially since the opportunity cost of them hosting the Games in general is lower as they would likely already have most of the infrastructure required.
The Tokyo Village has already received favourable reviews from athletes on prominent news and social media platforms, enhancing its image for prospective buyers even more. Private developers would be responsible for ‘specific aspects’ of development due to their ‘capabilities and know-how’ to turn the former Village into a ‘new and convenient community where a diverse range of people live and interact with ease and comfort’ under a public-private partnership. Looking back at previous Olympic Villages starting from Athens, the successful cases tend to have some amount of private involvement.

Furthermore, it appears that the development has been carefully planned out with long-term environmental goals in mind, similar to the successful cases of Olympic Village development – as stated on the website, they hope to ‘prepare an environment that will be passed down to the next generation’. Although not permanent, the viral cardboard beds that the athletes slept on is already an indicator that sustainability is a prominent element of this year’s Village. Environmental stability is an attractive element for prospective buyers and could increase the property’s value. Moreover, developers plan to install a hydrogen energy system and to use AI to forecast power demand, conserving energy. A ‘real forest’ is also in the works, and Harumi Flag hopes to create an ecosystem, complete with a hybrid irrigation waterscape and animals. The website continues to outline the effort being put into the design and redevelopment of the area, for example noting that the skyline would create a ‘rhythmic silhouette’ (translated), and outlining careful details such as light controls for ambience, non-slip pavements and more. These design details hint at the in-depth and long-term planning being put into Harumi Flag, which is a good sign for the future.
During Phase 1 of sales to the public in May 2019, where 600 flats were released, there were already 7 applications for every flat released. In July 2019, more than 2,000 applications were made for the further 900 flats put on sale as well. Although sales were halted due to the pandemic, they are expected to resume following the Olympics this autumn. Whether or not demand would remain as significant remains to be seen, however, when looking at the state of the real estate market in Tokyo, prospects seem to be positive. Owing to Japan’s extremely low borrowing cost, there is ‘persistently high occupancy, stable and resilient rental income and attractive pricing’, says South China Morning Post, even calling Japan’s real-estate market ‘Asia’s star performer’.
Of course, there are concerns. The lack of communication from developers to buyers about the delays due to the pandemic have led to buyers’ complaints making headlines, which may deter other prospective buyers. Market trends cannot be determined for sure either. Only time will tell, but for now, the future of the Tokyo Olympic Village certainly seems a lot more favourable than that of Athens or Rio.
Otis Worldwide Corporation (NYSE: OTIS) released the results of a three-month academic study that investigates how elevator airflow affects potential exposure to the COVID-19 virus and a science-based approach for how to mitigate that exposure in elevators.
Findings show the significant amount of air exchange present in most elevators combined with simple mitigation strategies, including all riders properly wearing a surgical-style mask and the installation of a common type of air purification system, puts an elevator ride on the lower end of the exposure spectrum.
The study indicates strongly the provision of air purification system inside the lift car reduce the airborne transmission
The study was led by Dr. Qingyan (Yan) Chen, the James G. Dwyer Professor of Mechanical Engineering at Purdue, who is widely recognized for his research into the spread of infectious disease through indoor air systems – and how to prevent it.
“Air exchange is important. the study findings concluded that the higher ventilation in an elevator, relative to the compared activities, results in lower exposure opportunity. If all passengers properly wear masks, the relative exposure risk drops 50%. Air purification, called NPBI, can reduce this by an additional 20-30%,”

The ventilation inside the Elevator is governed by legislation and code of practice from EMSD. It will be great if the position of inlet / outlet may be given due consideration in term of droplet dispersion and aerosol. Thus , in the absence of retrofit for outlet / inlet , the quick fix is to install the air-purification machine which can encourage the positive air flow.
There are different types of air purifiers in the market which can kill virus and improve air quality of the indoor environment. The size of your room is an important factor for choosing a suitable Air purifier. Bigger spaces will need larger air purifiers so make sure you choose an air purifier that can operate in a space that is 20-40% larger than the room for the best performance. GBE offers site inspection services for air quality control and recommends the air purifier for your best suit. Please contact us for more details.

Call it an oversight or yet another loophole in social-distancing measures, but Hong Kong is again gripped by a serious Covid-19 outbreak. Centred on a gym in Sai Ying Pun, the cluster on Friday accounted for 47 cases that contributed to a dramatic surge in the city’s daily number of infections to 60.
Whether it heralds a fifth wave of the epidemic, as some experts are suggesting, is irrelevant; what matters is that for all our experience with the disease, a foolproof approach to containing its spread has still not been formulated.
The super-spreading event at Ursus Fitness seemingly resulted from instructors and customers not wearing masks. They were not required to; authorities had exempted people from wearing masks if doing vigorous exercise, even in indoor public places.
This is despite Covid-19 being spread by people exhaling and that being more pronounced when they are exercising. Belatedly, the government has reinstated the requirement of mask-wearing. All gym staff in the city have been ordered to have a coronavirus test by Sunday.
The oversight has been highly disruptive; in addition to the staff and customers who have tested positive and the gym’s closure for deep cleaning, 240 people who visited recently have had to be quarantined. Some were believed to be bankers, lawyers and educators, and offices and colleagues have been affected.

According to The Wall Street Journal, after urging steps like handwashing, masking and social distancing, researchers say proper ventilation indoors should join the list of necessary measures. Health scientists and mechanical engineers have started issuing recommendations to schools and businesses that wish to reopen for how often indoor air needs to be replaced, as well as guidelines for the fans, filters and other equipment needed to meet the goals.

The latest outbreak served as a dire warning for Hong Kong. Covid-19 shined a harsh light on how ventilation can impact business continuity and endanger capex investment. Ventilation provision has become a strict prerequisite for businesses that comes before any initial capital investment and expenditures in order to ensure business continuity.
Obviously, all operations require ventilation, but what the standard of ventilation is and how to achieve it? The laws involved are from Schedule 2 of Public Health and Municipal Services Ordinance (Cap.132) and the Buildings Ordinance (Cap. 123). The former legislation is to control “SCHEDULED PREMISES” where crowded space is anticipated while the latter legislation deals with office space.

The current standard enforced in ventilation in office buildings is the volume of “air supply”, not numbers of air change. There is a huge difference between these two concepts. Air change, which is repeatedly mentioned by the microbiologist, is NOT mentioned by the law.
To achieve the required air change standard, the ducting quantity and sizing is likely almost double than that of normal air supply provision, making it almost impossible for many offices and premises to achieve. Developers are used to providing the minimum standard as required by the law, and not catering to users nor designed for preventing viral outbreak.
Along with WFH, Social Distancing is an implied feature of our society today. With the slow adoption of the vaccine due to issues stemming from logistics and mistrust, we can expect that limitations on physical gathering may still be in place for the better of 2021. This means that businesses and schools may experience intermittent closures, and productivity technologies such as Zoom will become a more permanent part of work.

While air change with external air involves substantial ducting engineering, many operators may consider building the internal circulation system to significantly improve the air quality. There are different types of air purifiers in the market which can kill virus and improve air quality of the indoor environment.

To boost the housing supply is the urgent needs in today HK. Although many resources such as transitional housing and new town development are allocated , GBE has been working on two interesting cases which are to convert the “non-domestic space” to domestic usage. We love to sharing our experience to all reader.
There are many technical consideration to the conversion. To list some, the issues cover the “GFA” , “site coverage”, natural lighting and ventilation, open space, Fire safety are all in the radar . On top of this , some tricky issues such as concrete cover ; width of re-entry for open space; barrier free access ; provision of gas aperture , Kitchen, sanitary fitment and the clear headroom for the domestic space are all counting on.
It is technically complex to resolve all the issues in one scheme. We have to prioritise the amount of effort to resolve each problem. Honestly , some of the technical hurdle may be too costly to resolve or even not possible to overcome
Among all the hurdles, the GFA and site coverage are the most pertinent and profound factor. We have had a blog talking about the GFA conversion. Honestly , in the case of conversion, we usually have to rebuild the entire GFA calculation and site coverage from scarp. It boils down to the classification of site, open space and roof cover area. It is highly tedious but technical process.
Many peers usually have the impression that these are resolvable and always undermine the inherent difficulties. Let us share you one point, the importance of the RHS and prescribed windows are always in the play. Since the RHS is dictated much by site surrounding and site boundary, it eventually restricts the design of light/ventilation very much
The same hurdles happens to the fire safety. Some of the professional may overlook the essence of the concrete cover and believe the fire proofing materials be helpful. Unfortunately , the clear headroom of the space is always very limited and the resulted headroom after the new fire protection layer added may lead to inadequacy, it sounds ridiculous but it did happen.
These are not usually posing difficult , but the problem raised from the gas aperture for the bathroom, the RHS for kitchen and the drainage provision for the sanitary fitment. The gas aperture’s design demands a lot of the space consideration while the kitchen needs the RHS. When all these factors come together, the layout of the apartment becomes quite challenging
While a lot of resources have been allocated to MiC , Transitional housing and New town development , we can see there are some abandoned or under-utilised space in urban area , which can be converted into the habitation purpose. We have attempted successfully such conversion in some old districts in Hong Kong. We hope we can bring more similar cases for sharing in future
There is always an indispensable relationship between buildings defects, structural stability, and public health. In general, non-structural cracks, structural cracks, concrete spalling, defective external wall finishes and water seepage, etc can be the common types of building defects, which can be easily found in buildings in which do not receive proper maintenance and repair.

Photo showing external wall tiles was found missing
Today, as a surveyor graduate trainee, I want to share some causes for the development of building defects. There can be a combination of factors in causing the above-mentioned defects. All property will face some sort of defects during its life span. As a surveyor graduate trainee, we shouldn’t solely focus on the physical look of building defects, we need to observe the surrounding environment and the actual usage in concluding the cause of the particular building defects.
Design, material, construction, usage, and maintenance are the common angles in diagnosis the causes of defects. Taking concrete spalling as one of the examples, given the design stage, when the building is located near the sea, the chloride attack raised from the sea may corrode the steel bar. With the corrosion of the rebar, the volume of rebar inside the concrete will expand 8 times. Crack and concrete spalling may be found. At the same time, concerning the construction stage, the high water-cement ratio may bring void for the concrete surface due to the increase in permeability, which has the potential possibility to enhance the corrosion of rebar (you can refer to the blog from GBE dated on 28 June 2020). From the above reasons, we understand that the building defects may not be caused by a single reason only. It is the responsibility of the professional to conduct a detailed building inspection before jumping to a conclusion.
Photo showing the stage of rebar corrosion (retrieved from structural engineering blog)
Water Seepage is also a common building defect in aged buildings. The sources of water may come from rain, groundwater, element, condensation, plumbing, drainage, and user activities. When we observe some symptoms like water stains, water dripping, rusty stains, peeling of paint during the inspection, suspected water seepage maybe happened. Before diagnosing the source of water seepage, a preliminary desk study is required (if you wanna know about the details of desk study in how to tackle the annoying issue comes from water dripping in the living area, you mustn’t miss the blog from GBE dated on 4 Jan 2021). We may need to collect some background information like the location of dampness, the frequency of occurrence, the extent of the dampness, repair record, any complaints on the water seepage in identifying the source of such dampness. Visual Inspection and some testing tools like moisture mete can be applied in determining the source of seepage. In some cases, where we suspected the water seepage was caused by the defective waterproofing membrane from the upper unit or roof, a water ponding test may be adopted. At the same time, when we suspected the water dampness was raised by the leakage of the plumbing pipe, a meter test can be adopted in deterring the actual source of such seepage.

In order to maintain a safe and healthy environment for occupants, routine inspection, repair works, and maintenance works are suggested to carry out in every building.
The impact of Fire Safety Code in Hong Kong
The fire safety code has experienced a few rounds of reform. The most influential reform we opined was the code published in 1996 and also the code in 2011. While there are many honorable peers have shared the view to both code applicable in Hong Kong, GBE found one interesting HK-unique escape staircase arrangement which have been prevailing in 2 decades ago. This the verandah space intercepting between the apartment units and the requirement staircase (usually scissor-type)
Verandah Space being merged
This verandah space was a space designed in half-open to the external air. The space is connecting between the staircase and the apartment unit through the fire-rated doors. Driven by congested space in Hong Kong, some verandah, in this case, has been enclosed by the window and merged to the apartment units. This was deemed to be against the fire safety code or approved plan.
GBP for showing the Typical location of the verandah in a domestic unit
The Provision of HK CAP 502
In 2007, the HONG KONG CAP 572 Fire Safety (Buildings) Ordinance has been put into enforcement. The “Purpose Of Ordinance” is cited in clause 2 of Cap 572 and We copied here as follows.
This ordinance is aimed to provide protection from the risk of fire of occupants, users, and visitors to certain kinds of composite buildings and domestic buildings.
The law further explains the requirements including fire service installation and equipment and fire safety construction for different kinds of buildings in its Schedule 1 , 2, and 3 correspondingly. The governing requirements stated clearly is to apply the Code 1996 as the “standard” to satisfy the intention of this Ordinance. Thus, the said “Verandah” enclosure or modification is likely in this radar.
What did Code in 1996 talk about the “Verandah”
In our view, there was no direct elaboration to the “veranda” being designed for the intercepting lobby between the required staircase and the unit. From the MOE code 1996 and FRC 1996, there was a few relevant paragraphs which came up eventually the “veranda” application as a protected lobby. Since the author was not the Code writer nor in an authoritative position to comment, this blog of write-up serves to trigger some interesting discussion.
The provision of the “Protection” lobby was written in clause 13.5 in MOE 1996 and the design of “Protection lobby” was explained in 11.3 FRC 1996. Nevertheless, the enclosing wall of the Protected lobby was further explained in clause 11.7. Honestly, it was a complex integration of different clauses at different code and could easily lead to various explanation outcomes. This undesirable situation such complex set of codes has been improved in lately 2011 code.
The interpretations of Protected Lobby stated in MOE 1996 Code
The design of “Required staircase and protected lobby” was explained in Clause 11.3 at FRC 1996 Code
The Clause 13.5 in MOE 1996 Code
Indeed, the old 1996 code has remarked very clearly in clause 13.5 MOE 1996 code that “such lobby shall be designed as a common area and an integral part of the staircase so that it could not be readily incorporated as part of any adjacent unit(s) of accommodation” The 1996 code did aware the issue of merging the protection lobby to the private unit. Nevertheless, the complex nature of the set of codes 1996 which led to different explanations may undermine the intention in clause 13.5.
Plan for demonstrating the Verandah between the required staircase and the apartment
Above is another example where the “Veranda” was inserted between the escape staircase and the apartment. Interestingly, the kitchen doors also opened to the verandah. It was believed that this layout configuration is hardly survivable in today’s Code.
Following with our part 1 discussion, we now share another hot topic about coating applied on the aluminium. “Self-cleaning” is indeed a merchants’ name . The behind sciences are varying from among different manufacturer. We have conducted some comparison among different materials being applied to the cladding surface.
In short, there are a few theories behind the “self-cleaning” . One typical approach is to create the surface which reduce the water surface tension. When the water droplet lands on the surface, the water droplet has formed an wetting angle to the surface of cladding. The stronger the water tension, the more acute the wetting angle is. The below diagram explains the wetting angle and how it carries the dirt / stain / attachment on the surface. Different manufacturer has formulated different chemical materials to reduce the water tension and flatten the wetting angle. The water is to carry and flush away the dirt. The most typical chemical approach is to create the coating surface which offer better hydrophilic (hydrophilic is origin from latin word, the word philic means love).
Another theory is by “Photo-catalytic Oxidation” . We are not Chemist and cannot cite the theory . Nevertheless, we found one extract from “Chemosphere 193( 2018-198-206)” , there explains the “photo-catalytic oxidation” with the below graphic. In short, it is the oxidation process to the VOCs by UV and Photon. This is again alleged by many peers as ” self – cleaning” , but obviously the theory is very different from “hydrophilic approach”
To the contrary of “Hydrophilic” , some manufacturer applied the opposite ; hydrophobic approach. The theory behind is to keep the strong water tension of the droplet and let the droplet to “PICK” the dirt away. From our very preliminary scanning , this technique was more relying on the water – repellent nature ,
We have encountered different approaches in the market. All suggest their “self-cleaning” properties. We try to cite some examples to illustrate different theory behind . We are not in the position to comment each performance and indeed it is difficult to do comparison. We hope this articles can offer some ideas for future research
Kansai Paint :
One of the product is made by Kasiai, we were given the understanding that the materials is silicon-based modified resin materials with their own additive untold to the public. This is to create the “Hydrophilic” by flush and deliver the dirt.
Hydrotech from TOTO
Hydrotect is the tradename by TOTO. We extract their self-allegation from their official website. In short, they claimed their coating technique is photocatalytic which is to OXIDE the VOCs in the air. Their website further suggests this “Hydrotect” can offer the hydrophilic surface to flush the dirt
XX Sheet film paper
A manufacturer , named to be untold here, claimed that there film sheeting offer the self-cleaning. We cannot identify their theory online. Nevertheless, we did a quick water spray test on the surface. We noticed that the water droplet kept intact on the surface and did not appear wetting pattern which is for flushing the surface. From the picture below, the water – droplet keeps visually keeps the sharp and the droplet drip pattern is in the form of line.
Fire safety can be regarded as one of the primary considerations in building designs. The terms of fire safety cover a wide range of building concepts, ordinances, and regulations under the law. When we consider the fire safety works in banks, the concept of Fire Safety (Commercial Premises) Ordinance should not be omitted. The introduction of FS(CP)O is one of the ordinances which aims to provide better protection to the occupants and visitors on certain kinds of commercial premises.
Prescribed commercial premises and specified commercial buildings are under the scope of the ordinance. For the captioned the premise, they are required to update that fire safety construction including means of escape, means of access, fire-resisting construction under the Code of Practice for the Provision of Means of Escape in Case of Fire 1996, Code of Practice for Fire Resisting Construction 1996, Code of Practice for the Provision of Means of Access for Firefighting and Rescue 1995 respectively. Also, the premises required to update fire services installation following Codes of Practice for Minimum Fire Service Installations and Equipment and Inspection, Testing, and Maintenance of Installations and Equipment 1994 when the total floor area exceeds 230 square meters.
As a building professional to cope with the above issue, a desktop study needs to be conducted first. It is essential to calculate the number/width of the exit door and exit route following the purposed usage of the premises. The comparison of the recorded plan and Fire Safety (Commercial Premises) Ordinance may draw attention to the fire safety deficiencies. The site visit is followed to identify the deficiencies. fire services system always associates with water supplies and electricity. For the aged building, some non-emergency services like electricity will be located in the exit route. However, those non-emergency services did not enclose by FRR materials. It may post a potential fire hazard. Insufficient width of the MOE route, insufficient number of exit routes to the required staircase, presence of the fire shutter in the exit route, absence of exit sign, absence of the exit door, etc are the common scenario for the aged commercial premises to deal with the ordinance. The reasons for the above deficiency can be caused by certain reasons including the change in use, the absence of the fire safety ordinance during the construction period, and unauthorized building works by the owners.
In a highly congested urban context, how can a building stand out from the backdrop and become memorable ? There are strategies such as a practical internal layout, modern interior design and impressive building facade. Since buildings are usually arrayed in highly dense urban areas, the building facade becomes the first impression and first touch in many metropolitan cities. To create a distinct impression in international city likes Hong Kong, the architectural design created by powerful multi-cultural collaboration is the bespoke element underpinning the design solution.
It is to the benefit of future users, landlords and every stake-holder of the development when the building is positioned and presented in the right site, right angle, right context and right location. To gear the architectural design toward practicality rich solutions, a down-to-earth technical analysis becomes profoundly important. K.P.D.O + GBE like many leading edge internationally award-accredited architects, believes a good balance of design, usage, layout, cost, and site features are essential to the development.
Grateful and thankful to collaborate, rather than presenting a simple yield diagram, K.P.D.O.+GBE. presented an aspirational solution showing the full site potential. K.P.D.O+GBE has analysed the details, negated technical deal breakers and prepared a sensible and approvable layout for the future user’s consideration. The turn-around for these are 6 days only. This assignment showcases and highlights our strong ability to find additional value whilst producing distinctive and memorable architecture.
