A pet dog repeatedly tested weak positive for the COVID-19 virus, indicating a low-level of infection with the virus, the Agriculture, Fisheries & Conservation Department said today.

The department first collected test samples from the dog on February 26. It detected low levels of COVID-19 virus from its nasal and oral cavity samples on February 27.

The dog also tested weak positive for the virus when the department repeated the test on February 28 and March 2.

Experts from Hong Kong University’s School of Public Health, City University’s College of Veterinary Medicine & Life Sciences and the World Organisation for Animal Health have been consulted, and unanimously agreed that these results suggest that the dog has a low-level of infection and it is likely to be a case of human-to-animal transmission, the department noted.

The dog has not shown any signs of disease related to COVID-19. It is currently under quarantine at the animal keeping facility at the Hong Kong Port of Hong Kong-Zhuhai-Macao Bridge. The department will closely monitor the dog and repeat the test later.

To ensure public and animal health, the department strongly advises that mammalian pets from households with COVID-19 infected people, or close contacts of infected individuals, should be put under quarantine in the department’s facilities.

The department emphasised that there is currently no evidence that pets can be a source of infection of COVID-19 and under no circumstances should people abandon their pets.

The Agriculture, Fisheries & Conservation Department today said genetic sequencing tests are being carried out on the pet dog of a confirmed COVID-19 patient which could reveal if the virus has mutated or not.

The department's Assistant Director (Inspection & Quarantine) Dr Thomas Sit told a press briefing this afternoon that the coronavirus is what is known as an RNA virus which eventually mutates.

“That is why the University of Hong Kong School of Public Health needs to do a genetic analysis to compare this dog’s genetic sequencing to the virus isolated from the patient so that they can compare. So if it is totally identical, then there is no mutation. The testing is still ongoing.”

Dr Sit reiterated that international experts agreed that the dog has a low level of infection, despite its blood tests not being ready yet.

“From the first sample to our last sample tested, it has already (been) six days. The dog’s nasal or oral mechanism, their secretion they should have - if contaminated - they should have a way to clean the virus, it would not stay for that long if it was just a contamination.

“I think it will take at least five or seven days for the blood results because it is not an easy test, it is not a quick test. We need to grow a virus and then neutralise the serum, so it takes some time.”

He added that it was too early to say whether animal-to-animal transmission was a possibility.

“At this stage, we do not have enough data to have a 100% answer as to whether it is infectious to other dogs or not. But if the dog’s owner is positive, it is better to take precautionary measures to prevent onward transmission.”

Dr Sit also advised dog owners to wash their hands, wear gloves and try to stop their dogs from licking their surroundings to prevent the virus from spreading further.

Chief Executive Carrie Lam today visited Tai Mo Shan Country Park to inspect its management services amid the COVID-19 epidemic.

She was accompanied by Secretary for the Environment KS Wong and Director of Agriculture, Fisheries & Conservation Dr Leung Siu-fai.

Mrs Lam visited personnel working at the park’s visitor centre and Twisk Country Park Management Centre of Tai Lam Country Park.

She observed how they enhanced campsites and associated facilities, improved hiking trails with natural materials, provided more lookout points for people to enjoy the scenery and strengthened services at visitor centres.

Mrs Lam learnt about the department’s anti-epidemic measures and management work, including running temperature checks on all park visitors.

Noting that the number of visitors in various country parks increased by 25% in February, Mrs Lam praised staff for their commitment to strengthening anti-epidemic work to safeguard public health.

The department enhanced its promotions and public education on anti-epidemic measures and protecting the environment through various means including social media and the networks of partner organisations.

Mrs Lam also visited a refreshment kiosk to learn about its business.

The department has provided rent concessions to all kiosks in country parks and will extend such relief measures until September this year to help shop operators during these difficult times. 

Mrs Lam said she appreciated the kiosk’s efforts to protect the environment and reduce waste and disposable plastics, which encourages people to adopt a greener lifestyle.

She also appealed to the public to exercise social distancing while enjoying the countryside amid the epidemic.

People living in units 13 and 14 of the top six floors of Heng Tai House in Fu Heng Estate, Tai Po need to be quarantined as a precaution.

Hong Kong University Chair of Infectious Disease Prof Yuen Kwok-yung made the statement at a media briefing today after an expert team conducted initial epidemiological investigations in the building to find the cause of a new COVID-19 infection.

The new case announced this afternoon involves a 59-year-old man who lives on the 34th floor of the building.

Prof Yuen said: “There is a possibility that when the patients on the 32nd floor are defecating - we know now that the fecal material actually contains the virus - while they’re defecating the fecal material goes into the sewer system.

“There is a vent of air that comes through the venting pipe, which goes to the top floor and maybe aerosolised in the air and then the droplets try to settle but, while at the same time, when there’s a light wind blowing, in which the air current going over the rooftop carries the particles back into the top floors.

“And of course, the 34th floor is the top floor. That is the most dangerous, followed by the 33rd and 32nd floors.”

Prof Yuen added he is uncertain if the venting pipe will continue to produce more infected aerosolised particles.

“So it is just a precautionary measure that we must remove the residents from the top six floors in units 13 and 14 for a period of time.”

The Advisory Committee on Recycling Fund today announced the launch of the One-off Recycling Industry Anti-epidemic Scheme.

The scheme aims to help the recycling industry cope with the current economic situation and operational difficulties brought by the COVID-19 epidemic.

Around $100 million has been earmarked for implementing the scheme under Enterprise Support Programme, providing financial support for the operational costs of recyclers for six months.

The maximum funding limit for each recycler is $20,000 per month.

The funding period will cover from January 1 to June 30, making a total maximum subsidy of $120,000.

The scheme opens for application from today until June 30. Recyclers with operations on or before January 1 can apply.

The first instalment related to the subsidy for the first three months will be available from April onwards and the rest of the subsidy will be disbursed in the middle of this year.

The committee also decided to extend the earlier launched One-off Rental Support Scheme for another six months.

The scheme, which has been accepting applications for six months of rental support starting from October 2019, will now be extended to September 2020.

Upon the extension, the maximum funding limit for each recycler will be 50% of the rental or $25,000 per month, whichever is lower.

The maximum rental funding limit will be raised to $300,000.

Application eligibility and requirements remain unchanged while the deadline has been extended to September 30.

Call 2788 5658 or email enquiry@recyclingfund.hk for more information.

The Agriculture, Fisheries & Conservation Department (AFCD) today said a pet dog has tested positive for the COVID-19 virus. 

The case involves a German Shepherd dog whose owners live in Pok Fu Lam. This follows an earlier case in which a 17-year-old Pomeranian dog tested weak positive during repeated tests for the virus.

When the German Shepherd's owner was confirmed with COVID-19, it was sent for quarantine with another mixed breed dog from the same residence to the animal keeping facility at the Hong Kong-Zhuhai-Macao Bridge's Hong Kong Port yesterday.

No positive results were obtained from the mixed breed dog and neither dog has shown any signs of the disease.

The department will continue to closely monitor both dogs and conduct repeated tests on them.

It strongly advises that mammalian pet animals including dogs and cats from households with people confirmed as infected with COVID-19, or close contacts of COVID-19 infected people, should be put under quarantine in AFCD facilities.

The department emphasised that there is currently no evidence pet animals can be a source of COVID-19 for humans or that this virus can cause the disease in dogs.

Pet owners are reminded to maintain good hygiene practices and under no circumstances should they abandon their pets.

Hong Kong Observatory Director Cheng Cho-ming today said he expects four to seven tropical cyclones to hit Hong Kong this year.

Presenting the weather outlook at a press briefing in the afternoon, Mr Cheng also said the overall mean temperature for the year will be higher than normal.

“The way that we produce our temperature forecast is based on a couple of things. One is based on the worldwide climate model - what they forecast for this year - and also based on some objective indicators.

“Based on all these indicators we expect that the overall mean temperature this year will be above normal, and very likely, will have a high chance of reaching the top 10 positions.”

Reviewing last year’s weather, Mr Cheng noted Hong Kong experienced its second warmest winter since records began, with a mean temperature of 18.7 degrees Celsius.

There was only one day when the temperature fell below 12 degrees Celsius.

Additionally, Mr Cheng said the new Hong Kong Hiking Trail Weather Service webpage has been launched to provide weather information services to people taking part in outdoor activities.

He added the Observatory also collaborated with the Agriculture, Fisheries & Conservation Department to provide weather information at popular hiking hotspots via QR codes.

The Agriculture, Fisheries & Conservation Department (AFCD) and the Leisure & Cultural Services Department (LCSD) announced today that some of their facilities will be closed in light of the latest developments of COVID-19.

Country park barbecue sites and campsites of the AFCD will be closed from 6pm on March 28 for 14 days. There are 163 barbecue sites and 41 campsites under the management of the AFCD.

During the closure of these facilities, barbecue or camping activities in country parks will not be allowed and AFCD staff will step up patrols of the sites concerned and take appropriate action against any violation of relevant regulations.

Call 1823 for enquiries and visit the Enjoy Hiking website for updates on country park facilities.

As for LCSD facilities, its free outdoor leisure facilities will be closed from 6pm on March 28.

Other venues and facilities with services already suspended will continue to be closed until further notice.

All booking applications for the department's recreation and sports facilities, wedding venues, amphitheatres and non-fee charging leisure venues for non-designated use are also suspended.

Meanwhile, the Housing Authority will close its outdoor sports and recreational facilities from 6pm tomorrow until further notice.

The Government today said the first batch of subsidies amounting to $5.6 million under two relief measures for recyclers has been disbursed, while $5.6 million in subsidies had been approved under a management sector support scheme.

The two Recycling Fund measures aim to help the recycling industry cope with the current economic situation and recent operational difficulties arising from the COVID-19 epidemic.

The Advisory Committee on Recycling Fund announced in mid-March to reserve $100 million to launch the One-off Recycling Industry Anti-epidemic Scheme.

The scheme provides timely financial support to help with recyclers’ operational costs for six months. The funding limit for each recycler is $20,000 per month from January 1 to June 30, or $120,000 in total maximum subsidy.

The committee has also allocated additional funds to extend the earlier-launched One-off Rental Support Scheme for another six months, providing a total funding of $200 million to fight the virus and help the recycling industry ride out the difficult times.

The rental support scheme, which benefits street-corner recycling shops and recycling sites, originally ran from October to March. It has been extended for six months until September this year, totalling 12 months.

The monthly rental subsidy for each recycler is capped at $25,000, setting the maximum total rental subsidy at $300,000.

Separately, the Anti-epidemic Support Scheme for Property Management Sector has approved 205 applications involving around $5.6 million in subsidies to benefit more than 1,500 building blocks.

The relevant property management companies and owners’ organisations will receive notifications for subsidy disbursement shortly.

The list of properties for which applications have been approved is available online.

Briefing sessions were held earlier to introduce the scheme to the property management sector and owners’ organisations.

The Agriculture, Fisheries & Conservation Department (AFCD) announced today that country park barbecue sites and campsites will remain closed until April 23.

The 163 barbecue sites and 41 campsites managed by AFCD have been closed since March 28. Given the latest development of COVID-19, the department has decided to extend the closure.

During the closure of these facilities, no barbecuing or camping activities are allowed in country parks.

AFCD staff will step up patrols of these sites and violation of relevant regulations will be subject to prosecution.

Call 1823 for enquiries or visit the Enjoy Hiking website for updates.

The department also reminded people visiting country parks to maintain personal and environmental hygiene and maintain social distancing.

The maximum monthly rental subsidy for each recycler under the One-off Rental Support Scheme will be increased from $25,000 to $37,500, the Environmental Protection Department announced today.

To help the recycling industry cope with the current economic situation and operational difficulties due to the COVID-19 epidemic, the Recycling Fund has allocated $50 million in additional funds to raise the scheme’s subsidy level.

The fund has now earmarked up to $250 million in total funding to fight the virus and help the recycling industry ride out difficult times.

On April 15, the Advisory Committee on Recycling Fund agreed to strengthen support under the scheme by increasing the rental assistance from 50% to 75% for the subsidy period from April to September.

The maximum monthly rental subsidy for each recycler will be increased to $37,500, while the maximum total rental subsidy for the 12 months will be increased from $300,000 to $375,000.

The scheme was launched last year to benefit about 500 street-corner recycling shops and 400 recycling sites.

In the face of current economic difficulties, the fund announced in February an extension of the subsidy period from six months to 12 months, lasting until September.     

As of April 9, the scheme has approved 103 applications, involving subsidies of more than $20 million.

The application deadline for the scheme is September 30. Enquiries can be made to 2788 5658 or via email.

The Government today announced that applications are open for several support schemes following the funding approval of the second round of the Anti-epidemic Fund and other relief measures by the Legislative Council Finance Committee.

The Club-house Subsidy Scheme, which provides a one-off subsidy of $100,000 to eligible club-houses, is now open for application. The deadline for application is May 18.

Upon submission of the completed application form and supporting documents, the disbursement of subsidies could generally be made in around two weeks.

The Travel Agents & Practitioners Support Scheme and the Hotel Sector Support Scheme are also open for applications, with the deadlines on June 15 and May 18 respectively.

The Subsidy Scheme for the Refuse Transfer Station Account Holders for Transporting Municipal Solid Waste, which offers a one-off subsidy of $8,000 to each of the eligible private municipal solid waste collectors operating in the first quarter, was also endorsed.

To ease the application procedures, the Environmental Protection Department will post cheques to recipients of this special subsidy in about a week after the funding endorsement.

Meanwhile, the total guarantee commitment of the Special 100% Loan Guarantee under the SME Financing Guarantee Scheme has been increased to $50 billion.

The maximum loan amount per enterprise has been increased to $4 million and the principal moratorium arrangement has been extended to the first 12 months.

The Special 100% Loan Guarantee will start receiving applications from April 20 and the application period has been extended to one year.

Non-residential and residential electricity accounts are benefitting from government relief measures, the Environmental Bureau announced today.

Under the measures, nearly 90% of non-residential electricity bills obtained a 75% subsidy for electricity charges in March, while 40% of residential electricity accounts enjoyed zero electricity charges in the first quarter of the year.

The Government announced about $2.3 billion in provisions last December to provide an electricity charge subsidy to each eligible non-residential electricity account holder to cover 75% of their monthly electricity charges for four months, subject to a monthly cap of $5,000.

The Budget further provided $2.9 billion to extend the subsidy period to eight months.

According to the bills issued by the two power companies in March, 360,000 non-residential bills obtained a 75% subsidy. This is close to 90% of the total eligible non-residential tariff bills.

To balance the impact on people's livelihood of the recent transition to cleaner electricity generating systems in Hong Kong, the bureau implemented the electricity charges relief scheme in January 2019.

A monthly electricity charge relief of $50 has been granted to each eligible residential electricity account for 60 months.

To help the public cope with the challenging economic environment, the Government implemented a new round of one-off electricity charge subsidy schemes in January.

A subsidy of $160 will be credited to each residential electricity account from January to November, while $240 will be credited in December.

From early this year, over 2.7 million households have been benefitting from both the electricity charges relief measures and the electricity charges subsidy. The bills of the two power companies indicated that 40% of residential electricity accounts, representing 1 million households, enjoyed zero electricity charges.

The bureau called on the community to cherish environmental resources, including saving energy and electricity to mitigate climate change and improve air quality.

The Agriculture, Fisheries & Conservation Department (AFCD) today announced that its barbecue sites and campsites in country parks will be closed until May 7.

It made the decision in light of the latest development of the COVID-19 epidemic and to reduce social contact.

All of these sites have been closed since 6pm on March 28.

During the closure of these facilities, no one should carry out barbecuing or camping activities in country parks.

AFCD staff will step up patrols of the sites and violation of relevant regulations may be subject to prosecution.

In the past two weeks, AFCD took enforcement action against 34 people who carried out barbecuing or camping activities in country parks.

The department will continue to closely monitor the situation and review the arrangement as appropriate.

For the latest updates on facilities in country parks, visit the Enjoy Hiking website.

Various government departments, together with volunteers today conducted a shoreline clean-up along the remote rocky beach in Kung Pui Wan, Tap Mun to remove two tonnes of refuse.

The Environmental Protection Department, the Food & Environmental Hygiene Department (FEHD) and the Marine Department participated in the operation.

The Inter-departmental Working Group on Marine Environmental Management said the beach, facing the windy and wavy sea, is not easily accessible by working vessels and the rough terrain connecting the rocky beach also increases the difficulty of routine cleaning work.

FEHD cleaners along with the volunteers packed the refuse and delivered it on foot to a nearby pier for temporary storage. FEHD staff then took the refuse to the Marine Department's collection vessel in batches for onward delivery to a rubbish collection point for centralised handling.

To minimise the risk of spreading COVID-19, the operation was carried out in groups of no more than four participants each. They maintained an appropriate distance from each other and paid heed to personal protection, including wearing masks.

The working group thanked the volunteers for taking part and called on the public to keep the countryside and shoreline clean during outings.

For information on clean shorelines, visit the Clean Shorelines facebook and Instagram pages.

Tenants of the EcoPark, country park refreshment kiosks and the Hong Kong Wetland Park will benefit from increased rental concessions for government premises.

To help tenants cope with the economic impact of the COVID-19 epidemic, rental concessions of government premises from April to September will be increased from 50% to 75%.

The Environment Bureau said tenants of the EcoPark, country park refreshment kiosks and the Hong Kong Wetland Park will receive additional rental concessions of about $3.6 million.

Together with the 50% rental concessions provided by the Government from last October to March, these tenants will receive concessions of more than $17 million within 12 months, the bureau said.

Meanwhile, tenants of the Hong Kong Wetland Park will receive a full rental waiver during the park’s closure.

The Government today announced that the Environment Bureau has disbursed about $6.5 million in subsidies to 809 private municipal solid waste collectors by cheque.

Under the Government's latest round of anti-epidemic measures, the bureau launched the Subsidy Scheme for the Refuse Transfer Station Account Holders for Transporting Municipal Solid Waste to provide a one-off relief subsidy of $8,000 to each eligible private municipal solid waste collector.

To provide financial support to the industry as soon as possible, the Environmental Protection Department, following funding approval by the Legislative Council Finance Committee, expedited the subsidy disbursement arrangement by waiving the application procedures.

The cheques have been issued and posted to all eligible private collectors.

Eligible collectors are refuse transfer station account holders who transported municipal solid waste to refuse transfer stations or landfills in the first quarter of the year.

The subsidy will assist them in increasing resources to enhance workers' personal protective equipment and strengthen the disinfection of refuse transport vehicles to curb the risk of virus transmission and maintain environmental hygiene.

In March, Hong Kong International Airport (HKIA) became the first in the world to be certified as an International Air Transport Association (IATA) Center of Excellence for Perishable Logistics (CEIV Fresh) Partner Airport.

Two of the airport’s cargo terminal operators, Hong Kong Air Cargo Terminals Limited (HACTL) and Cathay Pacific Services Limited (CPSL) have achieved IATA CEIV Fresh Certification, while Cathay Pacific recently became the world’s first airline to be certified.

IATA created the Centre of Excellence for Independent Validators (CEIV) to help organisations involved in the air cargo supply chain achieve handling excellence.

The certification underscores the speed, consistency and efficiency of all HKIA stakeholders when it comes to the treatment and transportation of perishable products.

It also helps to ensure food safety, and reduce food wastage and loss along the supply chain.

Quality benchmark

Hong Kong Air Cargo Terminals Limited Chief Executive Wilson Kwong said the main value of the accreditation is that it provides a universally recognised standard.

“It gives assurance to the various stakeholders that we have, and we are adhering to the highest possible standards.”

Both accredited cargo terminal operators HACTL and CPSL have set up perishable cargo handling areas with truck docks next to the apron.

As soon as the perishable goods are unloaded from the aircraft, they are immediately transported to the handling area.

The clearance and sampling checks have been streamlined to minimise the time taken to unload the goods. There are cold rooms set at tailored temperatures for various kinds of perishable cargo.

Their staff training and handling process have also been assessed and certified for their compliance with the global industry standards.

Cathay Pacific Services Limited Chief Executive Officer Jenny Lam noted that one of the challenges in meeting the certification standard is training its 2,000 employees in handling and storing perishable goods.

“They first have to identify what types of perishables they are, such as are they flowers, are they fruits, are they meat, so that they know how to segregate the storage.

“Secondly, they gain knowledge about certain fruits that cannot be put close to each other such as bananas and apples.”

Growth opportunities

In 2018, the airport handled about 380,000 tonnes of perishable cargo - a rise of 12% on 2017, with perishables accounting for about 8% of total air cargo volume.

Airport Authority Commercial Executive Director Cissy Chan explained that temperature-controlled air freight is one of the fastest growing segments in the air cargo market.

She believes with the new certification, the airport is well-placed to capture the increasing growth opportunities in the market for fresh and perishable goods.

“With the opening of the Hong Kong-Zhuhai-Macao Bridge, the transport time between the airport and the Greater Bay Area, notably the western part of the Pearl River Delta, will be further cut down.

“So this will put us in an even better position to become the transhipment hub for these perishables for the entire bay area.”

Extra backing

To support the growing demand for perishables, the Airport Authority has provided additional cool dollies, so there are now more than 30 for use by the whole airport community. It is also building apron shelters to protect the perishables from ambient weather elements.

Cathay Pacific Cargo Service Delivery General Manager Frosti Lau said they would work closely with the authority and its cargo terminal to see what new investments are required to handle the increasing demand.

The Government is actively exploring sustainable and innovative approaches to expand the city’s land resources. One viable source of land supply is rock cavern development.

The relocation of suitable existing government facilities to caverns can release above-ground sites for housing and other beneficial uses. This would reduce the amount of land occupied by them, as well as relocate facilities which do not need to be above-ground and are incompatible with the surrounding environment and land uses nearby.

Mountain move

Sha Tin Sewage Treatment Works is one such facility. It will be relocated to caverns in Nui Po Shan of A Kung Kok to release the existing site of about 28 hectares for housing and other uses that will enhance Hong Kong’s living quality and bring extended benefits to the community and environment of Sha Tin.

Drainage Services Department Sewerage Projects Division Engineer Brian Chan said that moving the sewage treatment plant to caverns minimises any adverse impact on the environment and community.

“The whole sewage treatment works will be put inside the cavern and the cavern will serve as a natural barrier fully enclosing the sewage treatment works. With the implementation of an effective odour management system, the odour impact to the community will be minimised.”

Mr Chan added that moving the existing plant, which has been in operation for more than 35 years, provides an opportunity to formulate a long-term strategy for the ageing facility.

High-tech solutions

The relocated Sha Tin Sewage Treatment Works will consist of several caverns.

A successful local example of accommodating facilities in rock caverns is Stanley Sewage Treatment Works on which the layout for the Sha Tin treatment plant is based.

To reduce the required cavern space and shorten the construction period, advanced sewage and sludge treatment technologies will be used.

Water recycling is a multi-stage process in wastewater treatment plants.

Mr Chan explained that moving bed biofilm reactors will be used in the secondary treatment process at the relocated Sha Tin plant as they require less space than the traditional wastewater treatment.

“Compared to the conventional method, there will be some biofilm carriers inside the reactor and this biofilm carrier will enlarge the surface area for the biological treatment and therefore, the overall size will be reduced. In terms of the sewage treatment process, there will be about a 20% reduction in the areas.”

Sha Tin Sewage Treatment Works serves a population of about 630,000 in Sha Tin and Ma On Shan, which produce 250,000 cubic metres (m3) of sewage daily. After the relocation, the facility will be able to handle 340,000 m3 of sewage per day.

The first phase of works to relocate Sha Tin Sewage Treatment Works to caverns began in February. The Drainage Services Department hopes to start the second phase from the end of next year to early 2021 with the excavation of the caverns. The department plans to move the whole sewage plant in five stages. The project is expected to be completed by 2031.

Members of the public can visit the department's website for more details about the project and its latest developments.

A 53-year-old building on Fa Yuen Street near Prince Edward, like most of the buildings in Yau Tsim Mong District, was in poor condition two years ago. Walls, both inside and out, were worn down, staircases were broken, and with electrical installation panels exposed on the outside. 

But with the help of various subsidy schemes launched by the Government and Urban Renewal Authority, older buildings are being given a new lease of life. The schemes include Operation Building Bright 2.0 (OBB 2.0), the Fire Safety Improvement Works Subsidy Scheme (FSWS) and the Lift Modernisation Subsidy Scheme (LIMSS).
 

Helping hand

Octogenarian owner-occupiers Leung Ting-lam and Chu Lai-chun have lived in this building on Fa Yuen Street for more than two decades. They welcome the improvements, which include a new metal gate and lift.

“Modernising the lift was done so quickly. It only took a few months and that was the most satisfying part,” said Mr Leung. Ms Chu agreed that the lift no longer breaks down so regularly.

It cost $800,000 just to modernise the lift. Add to that the other repair and maintenance works, and the total cost exceeded $3 million. Those who own a flat had to shoulder tens of thousands of dollars in the 10-storey building containing 19 units.

For seniors on a fixed income, it is not easy to cover the full cost of repair works. With the government subsidies, they no longer have to worry about the financial burden of upgrading their buildings on their own.

The lift modernisation work under the LIMSS is assisted by the Electrical & Mechanical Services Department. The department’s Assistant Director Raymond Poon said the subsidy can cover up to 60% of the total cost of the works - plus a consultation fee - with a cap of $500,000 per lift for eligible buildings.

For elderly owner-occupiers, they can receive the full cost of relevant works capped at $50,000 per domestic unit.

Up until August 1, the department received around 1,171 applications for the scheme involving nearly 5,000 lifts in the first round of applications. This far exceeded the quota of 1,400 lifts set for the round, a response Mr Poon described as overwhelming.

Apart from the LIMSS, owner-occupiers can also apply for OBB 2.0 and other schemes to cover maintenance costs.

In one 58-year-old Hung Hom building, residents had to spend more than $800,000 to paint the common areas, replace above-ground drainage pipework and other structural upgrades.

The building’s owners’ corporation has applied for several funding schemes to get some financial relief, including OBB 2.0. Under this scheme, elderly recipients can receive the full cost of the work, subject to a cap of $50,000. Other owner-occupiers can receive 80%, capped at $40,000.

As of August, the owners or owners’ corporations of 479 Category One buildings were prepared to carry out the prescribed inspection and repair works for the common areas of their buildings under OBB 2.0. They can do so on a voluntary basis to comply with the Mandatory Building Inspection Scheme (MBIS) statutory notices.

These buildings are in 13 districts. Among them, Yau Tsim Mong has the largest number of applications, followed by Kowloon City and Sham Shui Po.

More help ahead

In the future, another $3 billion will be injected into OBB 2.0. This means a total of $6 billion will be used to benefit 5,000 buildings.

Development Bureau Principal Assistant Secretary Jasmine Choi said they have received feedback from the community which hopes the operation will eventually allow younger buildings to join the rehabilitation schemes.

Upon review, buildings between 40 and 49 years old with an outstanding MBIS statutory notice not yet complied with will be accepted in the next round of applications.

Apart from these younger structures, OBB 2.0 will also accept buildings aged 50 and older, even if they do not have an outstanding notice.
