Pre-construction survey to MTR tunnel

We mange the construction risk and comply with MTR requirement before sub-structure works commencement.

We carried our pre-construction survey and monitoring proposal to record existing defect and initial record of MTR property including the wall, track rail inside the tunnels.

Underground Pipe Inspection – Tree Roots Issue

Underground drainage inspection can always help you to prevent blockage issues which may cause flooding in the future. Tree roots blockage is one of the common issues which may find easily near the plantation area. Regular inspection is necessary to prevent damage to the underground drainage system.

Here is one example which shows how tree roots can block the stormwater piping system.


Maintenance problem from wrong “water to cement ratio” of concrete cover mix

Concrete cover is the outer concrete layer serves to protect the rebar in RC structure. Its thickness and density dictates both the protection performance and fire – resisting ability.  The extract from the research paper by Albert K.H. Kwan in Department of Civil Engineering, University of Hong Kong , the concrete cover will become much permeability to water once the “water to cement ratio” exceeds 0.4. Adversely does the high water to cement ratio happen in many concreting process in Hong Kong. To account the reason behind , it is the slump of the concrete or the workability of the concrete affects the entire concreting process. The drawback from high permeability is very obvious . The concrete cover becomes lesser defensive against the water nor air penetration . The alkaline environment around the rebar is diminished along with the carbonation due from the air pollution



Transformation through Technology

While many are discovering how much they can achieve in the confines of their own home, residential properties have their inherent constraints, i.e. space, ceiling heights, loading, electricity capacity. Other constraints may be the scale of economy of certain services or ownership of equipment. It is still much easier for one to visit an imaging clinic than to purchase and operate a MRI machine at home or have the space and equipment for a soccer game at most home (at least not yet). While the above examples are driven by certain necessities, real estates involving discretionary spending such as retailers and leisure facilities face a much steeper uphill battle.

Some malls understood the attractiveness of online social media platforms, and were able to boost traffic with installations aiming at Instagram users, or rare Pokemon in their premises with correlation with Pokemon Go, the immensely popular AR mobile game. Others have even taken that idea to the full extent, namely the Ice Cream Museum, a source of many viral pictures and videos. Interestingly, these particular businesses require large floor plates and generous ceiling heights in heavy footfall locations, which are the kind of premises that retail tenants are divesting from due to poor profitability despite their marketing potential as flagship stores. Although many of these tech integration were successful, their repeatability is questionable and unable to bridge the online offline chasm exposed by Covid-19. With the onset of 5G technology, there shall be many ways and new directions where real estate can further its connectivity and technological integration. Landlords and tenants alike will need to explore ways to complement the technological trend to ensure commercial real estate will continue to be indispensable.

Bloomberg: Hong Kong’s Rich Are Preparing for a Worst-Case Scenario

While many predict Hong Kong’s real estate will experience increased pressure under the unresolved Covid-19 situation and National Security Laws, one must understand the Hong Kong real estate market is quite unique. While other mega metropolitan cities do provide relatively flush liquidity, their property markets have very different characteristics. Unlike Hong Kong, the bulk of the value of a development lies in the structure rather than the land, prices are driven by yield rather than speculations, and a host of fees and taxes that keeps prices certain sectors in check. London’s residential market, for example, is yielding multiples of that of Hong Kong’s while on the surface. However, landlord’s rental returns are quickly eroded by government fees and tax, and additional penalties for overseas landlord. While it is shrewd to have diversification, one should acquire comprehensive and holistic understanding of a foreign market before allocating one’s asset into it.

Regular Drainage Piping Inspection for Building


Regular pipe inspection is one of the important preventive maintenance for all buildings. During the coronavirus disease (COVID-19), all residential buildings may experience high usage of water as most of the people have to stay at home for work and daily life. The drainage pipe system may easily get blocked and the aging problem during this period, CCTV inspection can help to monitor the condition of piping system which can find out the potential problems.

The inner coating of the epoxy drainage pipes has been designed to withstand most chemical stress and resist abrasion. Made of an epoxy-resin regularly assessed, this coating benefits from continuous improvement to meet wastewater drainage increasing constraints. Its smooth surface enhances flow capacity and prevents incrustations and deposits. However, the workmanship may affect the piping durability and also create the risk of clogging. Therefore, close monitoring for replacement workmanship is also an important issue to prevent risk.


High Ceiling Inspection

GBE found the relax of headroom from PNAP has posed many difficulties to conduct professional inspection to above high ceiling. We made ourselves accessible with our own rising platform and wifi endoscope. Usually the drainage which poses the hygienic alert is hide above. Our way can ease many people pain.
