TKO Desalination Plant 將軍澳海水化淡廠
Appointed by China State Construction ( 中國建築), ETag has delivered a Smart Site Construction Portal at TKO Desalination Plant (將軍澳海水化淡廠). We have combined Autodesk Revit 3D Model and Google Earth to simulate the site environment so that everyone can view the site via Autodesk Forge in a web browser. Comparing with Drone photos, adopting Google Earth as background display is a cost effective option to enhance the outlook of the web site. Real time GNSS sensor data and IP camera video streams are embedded in the platform.
Large BIM Model Display in Web
When the user encounters a large model display (> 2GB), they usually select Navisworks format in the Forge output. However, it is not a good practice because most of the BIM information is lost. In order to maintain the BIM information and achieve the best display performance, SVF2 is the ideal choice. Autodesk Forge Model Derivative service produces SVF2 derivatives by optimizing and sharing meshes within the same Viewable, and even across multiple Viewables when possible. Because of this optimization, SVF2 format greatly reduces the Viewable storage size and speeds up viewing and loading performance. But note that SVF2 will take longer to translate. In the below video, it is a 2.8GB Revit model in a zip file and 80 linked rvt files are stored.
Revit Model Group Selection
When a Group is selected in the BIM model, you would like to select all the objects in it, determine the group name and other information about group member elements. It is very useful in a large amount of objects information display (e.g. curtain wall, window, structural frame, borehole ..). For e.g., a number of groups were created in Revit model by modeler. The user selects a group in the left hand side panel. The corresponding group members are displayed in the BIM structural model.
Chief Executive Carrie Lam visited AsiaWorld-Expo on 29-September to inspect the temporary hospital construction progress. Adopting Modular Integrated Construction (MiC) and Works Supervision System technologies, the project is expected to be completed in about four months. We are glad to work with China Overseas Holdings Ltd. (COHL) to deliver the Works Supervision System. It combines BIM, IoT and AI technologies. Features 1. Construction Progress Tracking via BIM 2. Helmet Detection by AI 3. Workers Distribution 4. Contractors List in real time 5. Video cam selection via BIM HKSAR Government News 政府新聞網頁
I am pleased to announce that HK Airport Authority has awarded the Event Broker contract to E Tag to deliver Solace Event Broker for HK Smart Airport's Event Driven Architecture (EDA). What is Event Broker? The primary purpose of a broker is to take incoming messages from applications and perform some action on them. Message brokers can decouple end-points, meet specific non-functional requirements, and facilitate reuse of intermediary functions. For example, an event broker may be used to manage a workload queue or message queue for multiple receivers. Using Event Broker for Microservices Communication You can use events to implement business transactions that span multiple services, which gives you eventual consistency between those services. An eventually consistent transaction consists of a series of distributed actions. At each action, the microservice updates a business entity and publishes an event that triggers the next action. The below figure shows a PriceUpdated event published through and event bus, so the price update is propagated to the Basket and other microservices. Event Broker == MiddleMan? How do you achieve anonymity between publisher and subscriber? An easy way is let a middleman take care of all the communication. An event bus is one such middleman. In the below figure you can see how, from an application point of view, the event bus is nothing more than a Pub/Sub channel. The way you implement this asynchronous communication can vary.
Vibration on Marine Crane
Appointed by HK Airport Authority, E Tag delivers a vibration measurement on a marine crane where at Skypier. Six wireless vibration sensors are installed on a marine crane to monitor the crane vibration in real time on various positions. The sensors are powered by batteries and the battery life can be lasted for 6 months in 7x24 monitoring.
Water Leakage Monitoring
Joint work with ChunWo Construction & Engineering to deliver a BMS + IoT solution in ASD (建築署) project The project is located at Water Resources Education Center (WREC) of Water Supplies Department (WSD). By combining IoT and BIM technologies, ASD property team can monitor the site BMS BACnet data in real time via the web client. In case the BMS system triggers an alarm, the system displays the alarm data on the BIM model and states its possible root causes on the web client. For example, the water pipe is highlighted in the below picture when a water leakage alarm is received from BMS system.
IoT at HK Airport
E Tag delivered a number of IoT projects at HK Airport. The data is collected in real time and trigger a push notification on mobile device when a value exceeds a predefined threshold value. 1. Vibration measurement on Escalator motors 2. Vibration measurement on water pipe 3. Flow rate measurement on water pipe by ultrasonic sensor 4. Automatic Water Meter Reading
Upper Deck Passenger Counting
It is our pleasure to deliver a passenger counting solution for Citybus. A passenger counting sensor is installed on the upper deck counting the passengers in real time. The system facilitates passenger knowing the upper deck seat availability without going up. Based on the pre-defined inputs, the display presents the seat availability figure in different colors "Green - Normal", "Yellow - 10 Seats Below" and "Red - Fully Occupied". The passenger counting system is currently available on buses deployed to Route 20, 22, 608 & W1.
Asset Registration in BIM
I am pleased to announce that E Tag is awarded by HK Airport Authority to deliver a BIM Asset Registration Tool. Because Hong Kong International Airport expansion and the Three Runway System (3RS) construction, the construction parties are requested to submit the asset data with building model together. The asset data schema is aligned with Airport Asset Management System ("AAMS"). BIM Asset Registration Tool Features: • The client can be deployed in an entry level PC. Targets general users • Supports IFC file format • Ease of data input operation • Performs the data binding between BIM elements (GUID) and asset items
Autodesk AIAB 2018 Presentation
Thank you for the invitation from Autodesk to present a topic of BIM + IoT. Traditionally, BMS is expensive and requires specialized installation, programming and maintenance. Using BIM + IoT monitoring a building, it greatly reduces the operating cost. The collected BMS data can optimize the building performance using your own way. Here is the ppt presentation material.
Bus Passenger Counting in Macau
It is our pleasure to announce our partnership with InfoMacro (澳門萬高信息科技) in winning a contract from Macau Gov't DSAT (交通事務局) to deliver a bus passenger counting system in a selected route. E Tag is responsible to deliver a hardware and software integration services. InfoMacro plays a local support and big data services.
