升降機及自動梯工程「零意外」目標

機電工程署在2013年11月舉辦的「合約工作安全研討會 ─ 升降機及自動梯」率先為業界建立一個平台，讓大家分享經驗，學習提升工作安全高水平，達致工地「零意外」的目標。

助理署長/3戴德謙先生於研討會鼓勵所有專業工程人員，為升降機及自動梯工程設定更高的安全標準，並多走幾步，以不斷求進及創新的精神，持續作出改善。他指出，只要我們堅持，「零意外」的目標是指日可待的。

現時全港有超過5,000位已註冊的升降機及自動梯工程人員，專責為全港七萬多部升降機及自動梯提供維修保養、安裝、優化及更新工作。要提高業界的安全水平，就需要各方的承諾、合作和努力。項目工程師必須制定明確的安全要求，並密切監察工地的安全水平和表現。與此同時，合約承辦商必須嚴格遵守合約要求，貫徹落實安全管理系統、採納業內的安全典範、利用創新的工作技術或工作方法等來保證工作安全。

機電工程署透過聘用14家維修保養公司，為各政府部門管理超過3,500部升降機及自動梯的維修保養工作。我們正為這些裝置進行獨立審計，以找出升降機及自動梯日常保養可加強改進之處，並探索應用業界公認的最佳做法和良好措施。我們的不斷努力，就是要確保乘客的安全和工作的安全，實現「零意外」的最終目標。


Zero Accident Target for Lift and Escalator Work

In the most recent “Contract Work Safety Seminar–Lift and Escalator Work” organised by EMSD in November 2013, we have taken the lead to build a platform for industry practitioners to share best practices and learn how to maintain a high level of work safety, aiming at zero accident in work sites.

Speaking at the seminar, Mr. Tai Tak-him, Assistant Director/3 encouraged all professionals to set a high standard of lift and escalator safety and go an extra mile to pursue innovation for continued improvement. He noted that zero accident could be achieved if we persisted.

Currently, more than 5,000 registered lifts and escalators workers are charged with the maintenance, installation, modernisation and replacement work for over 70,000 lifts and escalators in Hong Kong. To achieve a high level of safety, we need strong commitment and joint efforts from all parties concerned. Project engineers must set out clear safety requirements and closely monitor site safety standards and performance. At the same time, contractors must strictly observe contract requirements and implement a robust safety management system, making reference to industry best practices as well as developing innovative measures to enhance work safety.

EMSD also manages the maintenance of 3,500 lifts and escalators in government premises via 14 contractors. We conduct Independent Audit Inspection on those installations to identify areas of enhancement on routine maintenance and to explore the adoption of best practices and good measures. All our efforts target to secure passenger and work safety to achieve our ultimate aim of zero accident.




領導升降機優化工程

機電工程署現正推動全港的升降機和自動梯優化工程，為以身作則，我們更率先為政府物業的所有升降機進行優化工作，期望帶動私營市場業界加入提升舊式升降機安全水平的行列，使其升降機運作更可靠舒適。

全港的升降機於不同年代安裝和啟用，雖然安裝時已達當時的技術標準，但近年科技發展迅速，這些舊式升降機也有很大的改善空間。為此，我們特別製作「優化升降機指引」，列出為舊式升降機安全制訂的七大改善方案，包括安裝雙重制動系統、防止機廂不正常移動的裝置、防止機廂向上超速的裝置、障礙開關掣保護懸吊纜索、機廂門鎖及門刀，加裝對講機及閉路電視系統和自動拯救裝置等。

至於我們為政府升降機進行的優化工程，從2013年4月開展，分三個階段實施。我們向所有客戶部門提供一站式的解決方案服務，從初步評估、編製標書、執行項目、以至優化工程完成和恢復升降機服務。

在優化工作進行中，我們遇到不少挑戰。原因大部分場地都在使用中，暫停升降機服務肯定會為使用者帶來不便，尤其是對只有一部升降機的場地，如員工宿舍及社區中心等，故工程必須在最短的時間內完成。至於圖書館、法院大樓、文化中心和博物館等場地，我們更須盡力避免及減低在進行優化工程時可能帶來的噪音滋擾。

到目前為止，我們已為20多個政府建築物完成升降機優化工作，整個項目預計於2016年完成。屆時，承辦商應已熟習了升降機的優化工作，零部件的成本也應該愈來愈便宜，私營市場業界將更容易掌握舊式升降機的優化技術，確保公眾安全。


Leading Lift Modernisation

EMSD is taking the lead in lift modernisation in Hong Kong by enhancing all existing lifts in government premises, setting an example for the private sector to follow suit to make their lifts safer, more reliable and comfortable.

All the lifts in Hong Kong were installed in different decades. Although these lifts were installed to the level of technology appropriate at the time, rapid technology advancement in recent years means there is room for enhancement. Therefore, we have set out seven solutions for older lifts enhancement in the “Guidelines for Modernising Existing Lifts”. The solutions include installation of a double brake system, an unintended car movement protection device, an ascending car overspeed protection device, an obstruction switch to protect suspension ropes, car door mechanical lock and door safety edge, and adding an intercom and CCTV system and automatic rescue devices.

For the government lift modernisation project led by EMSD, it is carried out in three phases starting from April 2013. We provide one-stop engineering solution services to all client departments, from preliminary assessment, tender preparation, project execution to completion of modernisation and resumption of lift services.

In the course of modernisation work, we have encountered quite a few challenges. Most of the premises are occupied and suspension of lift services is a serious nuisance, especially for venues like staff quarters and community centres with only one lift. Modernisation work has to be completed in the shortest period possible. We also must pay special attention to mitigate noise that may arise from the modernisation works in libraries, court buildings, cultural centres and museums.

We have so far completed lift modernisation work for more than 20 government buildings. The aim is to complete the project by 2016. By that time, contractors will have become familiar with lift modernisation work and the cost of lift parts should become increasingly affordable. It will be much easier for the private sector to modernise their lifts to enhance public safety.




提升員工和飛機乘客安全

現懸掛在香港天文台氣象浮標上的儀器，由於儀器位於浮標的頂部，對日常維修工作構成潛在高空作業的危險。我們主動提出的改善方案不單解決了員工的安全問題，更促進了航空安全和改善飛機乘客的體驗。

目前，在香港國際機場對開水域設有五個直徑三米的氣象浮標，浮標上的儀器能自動收集和測量風力、氣壓、溫度和濕度等天氣資訊，通過無線電波，每十秒將即時資訊傳送到位於航空交通管制塔內的天文台機場氣象所。這對預測機場周邊地區的風切變尤其重要，並有助確保航空安全，因為如發現有風切變在機場範圍內出現，飛行員便要立即採取行動，停留在其預定的飛行路徑。

然而，攀爬維修籠至浮標頂部進行維修工作，容易對高空作業的工作人員帶來人體下墮的潛在危險。我們得到天文台和客戶部門海事處的准許，主動重新審視風速計支柱的設計，安裝一組密封式金屬齒輪箱，這樣，豎立在浮標頂部的風向及風速監察裝置便可輕易降下，工作人員便不需攀爬維修籠進行維修工作。新的設計既提升了工作安全，又不影響浮標的堅固性和穩定性。

我們與天文台和海事處成功合作解決維修氣象浮標的安全問題。同時，維修工作可以更有效率地完成，提升天文台氣象裝置的可用性，能更及時地向飛機發出氣象資訊，從而提供風切變的預警，為旅客和公眾加強航空安全。我們的同事也贏得客戶的認同和對機電工程署的讚賞。


Safety for Staff and Air Passengers

Our initiative to solve safety issues arising from maintenance work of the anemometer masts of the Hong Kong Observatory (HKO) weather buoys has contributed to better aviation safety and enhanced travel experiences.

Currently, there are five weather buoys deployed in waters off the Hong Kong International Airport. Each weather buoy comprises an automatic weather station mounted on a three-metre diameter buoy. The automatic weather station measures weather information such as wind, air pressure, temperature and humidity, and transmits the information by radio to the HKO Airport Meteorological Office located in the Airport Traffic Control Tower every ten seconds. The timely weather information gathered and transmitted by these buoys is particularly useful in estimating wind shear over the areas around the airport to ensure aviation safety, as significant wind shear requires immediate action by pilots to stay in their intended flight paths.

However, climbing over the maintenance cage of the weather buoy and up to the anemometer mast to carry out maintenance work for the wind sensor poses potential hazards of working at height for staff. With consent from HKO, the client department, and owner of the buoy, the Marine Department (MD), we took the initiative to re-design the anemometer mast by installing a gear box onto it so that the mast of anemometer erected on top of weather buoy could be lowered down and our staff were no longer required to climb up the cage for maintenance work. The new design has enhanced work safety without compromising the robustness and stability of the buoys.

Our collaboration with HKO and MD has successfully addressed the safety issue of weather buoy maintenance. At the same time, it ensures that the maintenance work be completed effectively and efficiently, thus raising the system availability of the installed instrument in issuing timely wind shear alerts to aircrafts in sea-breeze situations and enhancing aviation safety for air passengers and the public. Our colleagues have also earned recognition from the client who expressed appreciation to EMSD.

New Services for Hospital Authority and
Hong Kong Police Force

Our professional services for the Hospital Authority (HA) and Hong Kong Police Force (HKPF) have gained for us new and additional Service Level Agreements (SLAs) to reinforce their support to the general public.

North Lantau Hospital
The North Lantau Hospital (NLTH) is a new public hospital catering for the development of the North Lantau New Town and its growing population, as well as the needs of the Hong Kong International Airport and major tourist attractions in the area.

Upon commencement of operation of the new hospital in September 2013, the HA’s Kowloon West Cluster entrusted the operation and maintenance of electrical, mechanical, air-conditioning and building services system of NLTH to EMSD as a new venue of SLA services, to support the daily operation of the hospital.

Hong Kong Police Force
To ensure reliable maintenance of facilities for public order and safety, the HKPF has signed with EMSD two six-year SLAs effective April 2013. We now provide HKPF with total engineering solutions from testing, commissioning to replacement of plant and equipment.

The first SLA is a new contract for the provision of project management services for an estimated project amount of $50M per annum. Under this arrangement, we can plan forward replacement projects for the client and recommend state-of-the-art and more energy efficient technology to support the growing needs of HKPF.

Furthermore, we have also renewed the previous SLA for maintenance of engineering systems and vehicles, with service enhancements for the digital red light camera system, speed enforcement camera system, domestic appliances in quarters, cell sites and police motorcycles.

通過新腎科中心的連串挑戰

2013年12月2日的東區尤德夫人那打素醫院新的日間透析中心（腎科中心）開幕典禮，標誌着我們的努力成果，儘管我們在時間和運作上遇到許多的限制。

新腎科中心建於東區醫院東翼，合併了H8和K8病房，總面積達1,900平方米。由於港島東區腎科病人的需求量殷切，改造工程必須在2013年4月至8月期間完成，時間非常緊迫。機電工程署的任務是設計和安裝生物醫學工程系統及機電工程系統、管理十個承辦商，並須與院方的建築承辦商協調，以配合整體工程的進展。

我們專業及全面的服務，其中包括採購及安裝尖端的逆滲透淨水系統，這系統是目前在香港公立醫院中最大和最新的，可同時為36名病人提供服務。滲漏檢測系統則利用分區檢測的方法，能有效找出漏水的位置。而透析資料管理系統能整合病人的資料，於血液透析過程中能即時連線監控，從而提高病人的安全和管理效率，是香港目前唯一能夠連接不同品牌腎科儀器的系統。這一特別功能，不單有利整體設備管理，對將來的採購和更新腎科設備工作，都更具靈活性。

項目的另一重點是專為隔離病房及小手術室設計的獨立空調系統，能防止交叉感染，並為將來的營運提供了靈活性。

新的日間透析中心設計獨特，同時設有正及負氣壓的隔離病房，分別為免疫系統受損和患有呼吸性傳染病的患者提供服務。為配合日間透析中心的高標準要求，負氣壓隔離病房的通風系統設計和氣壓調控，是根據「嚴重急性呼吸系統綜合症（沙士）」病房的設計指引來設計。對於用以進行植入腹膜透析導管手術的小型手術室，其通風系統亦根據國際準則「衞生技術備忘錄」HTM 03-01的最高標準來設計。

為應付新中心的額外冷氣負荷，我們還利用最新的環保技術，安裝了六套冷水機組，以及其他建築裝置如消防系統、配電及電氣系統等，提高能源管理效率。


Ploughing through Challenges for
the New Renal Centre

The opening ceremony on 2 December 2013 marks the completion of our work for the new Dialysis Day Centre (Renal Centre) at Pamela Youde Nethersole Eastern Hospital (PYNEH), despite time and operation constraints.

With a total area of 1,900 m2, the new Renal Centre at PYNEH was built in the East Block connecting the H8 and K8 wards. Due to the large demand of renal patients in Hong Kong East region, the renovation work had to be completed in a very tight time frame between April to August 2013. EMSD was tasked with the system design and installation of the Biomedical and E&M Engineering Systems, managing ten contractors and co-operating with the Hospital’s building contractors at the same time to match the work programme.

Our professional and comprehensive services include procurement and installation of a cutting-edge Reverse Osmosis System, the largest and latest of its kind in Hong Kong public hospitals. It can serve up to 36 patients at the same time. The zoning approach of the water leakage detection system helps identify the location of water leakage. The Dialysis Data Management System consolidates patients’ information and enables on-line haemodialysis process monitoring, thus enhancing patient safety and management efficiency. It is the only system in Hong Kong that is able to connect renal equipment of different brands. This is essential to facilitate overall equipment management and provides flexibility in future procurement and replacement of renal equipment.

Another highlight of our project is the independent air-conditioning system specially designed for the isolation rooms and Minor Operating Theatre to prevent cross contamination and provide flexibility for future operation.

The new Dialysis Day Centre is uniquely designed to have positive and negative pressure isolation rooms for both immune-compromised and infectious patients. The ventilation system of negative pressure room and its pressure level is designed and maintained based on the design guideline of SARS ward. The Minor Operating Theatre is mainly for carrying out Peritoneal Dialysis Catheter Insertion. Its ventilation system is also designed based on the highest standard of international guideline Health Technical Memorandum HTM 03-01.

Due to additional cooling load required for the new Centre, six chiller units with green technologies for better management of energy usage were installed, together with other building services installations like the fire services system and power distribution & electrical system.

創新、綠色設計的數據中心空調系統

我們的小蠔灣數據中心主要負責為政府部門提供數據儲存服務，其中包括食物及衞生局的電子病歷檔案儲存。我們率先為小蠔灣數據中心的空調系統採用了創新的環保高效節能設計，預計可以提高整體散熱效能達20%至30%，此舉是支援客戶部門的環保措施。

這套獨特的空調系統是位於服務器機房內，採用一個屏蔽式熱氣流通道設計。該設計是由一個鋁質框架，利用聚碳酸酯隔板置於服務器機架頂部及每行機架兩旁所組成。屏蔽式熱氣流通道設計是一個高成本效益的解決方案，能把冷和熱的空氣分隔在不同的通道中。

以物理屏障完全分隔冷熱氣流通道，能防止再循環和旁通的氣流影響服務器設備上部分的冷卻效能。該系統除了全天候24小時為所有服務器提供更好的散熱環境外，電腦控制的空調機組的送風和回風溫度可相應提高，使空調機組發揮較高的冷卻效能。

該節能空調系統乃數據中心第二期擴建工程的一部分，項目於2013年2月開始，預計於2014年年中完成。


Innovative, Green Design for
Data Centre’s Air-Conditioning System

Siu Ho Wan Data Centre is responsible for the storage of data for various government departments and the Electronic Health Record of the Food and Health Bureau is one of them. Our initiative to redesign its air-conditioning system with innovative, energy efficient measures is expected to improve the overall cooling efficiency by 20% to 30% as a green measure to support client departments.

This unique air-conditioning system comprises a hot aisle containment design in the server room. Formed by an aluminium framework with polycarbonate inserts on top of the server racks and at the two ends of the row, the hot aisle containment is a cost effective solution to contain air in cold and hot aisles.

This physical barrier divides the cold and hot aisles completely, preventing both re-circulation and bypass air which significantly affect the cooling performance on the upper part of the server equipment. Providing better thermal condition to all servers 24 hours round the clock, the system also allows higher supply air temperature and the warmest possible returned air back to the computer air-conditioning (CRAC) units, so as to operate in an efficient manner.

The energy saving air-conditioning system is part of the Phase II expansion of the data centre, construction of which started in February 2013 and is scheduled for completion by mid-2014.

強化邊境安全

項目於2012年10月開始，以配合第二階段的邊境禁區範圍縮減，涵蓋落馬洲邊境管制站至梧桐河段。邊境禁區範圍縮減能釋放710公頃的土地供公眾使用。

新系統的亮點是採用了尖端科技，如利用視像分析技術和圍網偵測傳感器，去偵測任何於陸路邊境禁區附近出沒的非法闖入者、偷渡客或走私客。相比舊系統，新的偵測系統能大大降低了因惡劣天氣或野生動物所觸發誤報的可能性，從而更有效協助警務處監察邊境的工作。

我們將繼續支援邊境禁區範圍縮減第三階段的工程，整個項目預計將於2015年完成。

Reinforced Border Security

The new border fence protection system, installed by EMSD to match up the reduction of Frontier Closed Area (FCA) of Hong Kong, has reinforced the operation efficiency of Hong Kong Police Force (HKPF) and enhanced security along the Hong Kong border. The project was further extended to replace the old central control system which has been in use for almost ten years.

The project began in October 2012 to cope with the second stage of the reduction of the FCA, covering the section between Lok Ma Chau Boundary Control Point and Ng Tung River. The key benefit of this FCA section reduction was to release 710 hectares of land for public access.

The key highlight of the new system was the application of cutting-edge technology, such as video analytics technology and fence detection sensors to detect any intruder, illegal immigrant or smuggler near the land border restricted area. Compared to the old system, the new intrusion detection system reduces the possibility of false alarms due to adverse weather and wild animals, thus enabling more effective monitoring of the border.

We will continue to support the third stage of FCA reduction and the project is scheduled to be completed in 2015.
