Two invalid pipe culverts formed sinkholes at BJ Cove houses
Originally, there were two natural rivers/streams from the IJM Trehaus site and a nearby pond. No proper drainage system was implemented when housing development started, only two invalid hidden underground pipe culverts were built to channel the waters from the Bukit Jambul hill to Relau district.
It is a common sense that waters from the natural rivers or streams are natually running, seeped through underground even the surface is covered by land-filled soil or with man made culverts.
The following is an invalid underground pipe culvert from the IJM Trehaus site behind BJ Cove houses at Lintang Bukit Jambul 1:

Serious Drainage Issues
|A drain under construction by JPS to divert waters from the nearby pond|
Letter from Penang Dept of Irrigation and Drainage (DID or JPS) in 2015 blamed IJM failure to comply with sedement control plan (ESCP) when its Trehaus started in 2014.
Clearly, the underground pipe culverts leaked and waters seeped through the ground and multiple cracks, as it did not happen immediately but over a period of time!
Developers dishonored directives/letters issued by Penang City Council (MBPP – Majlis Perbandaran Pulau Pinang) in 2015 to rectify the damaged house
Developers have not honored their committments to rectify the damages despite acknowledged their liability as per letters from Worldwide Venture Sdn Bhd, an subsidiary of IJM Land since 2014!
Despite the underground pipe culverts declared invalid by JPS and the Penang City Council’s (Majlis Perbandaran Pulau Pinang, i.e. MBPP) issued stop work orders directing the developers, Worldwide Venture Sdn Bhd, a subsidiary of IJM Land to rectify the damages within 1 and 2 weeks time since 2015 (as per the above attached letters), multiple wall cracks, slabs collapsed, PBA water pipes burst, leakage charges, damaging ceiling, electrical DB board, and tiles fallen, broken/popped up, are still pending settlement and remedial works to be carried out by parties responsible for the damages since 2014 !!
IJM Land only started in December 2017 constructing new drainage to divert waters from Trehaus Site to the pond:
It is important that the pond should be made a Dried pond instead of existing wet pond on the following reasons:
i) The area was originally a natural river/stream where waters will
still be naturally running, seeped through underground even when the
underground culverts are to be closed/abandoned later.
ii) More waters are being diverted from the IJM site to the pond
However, damaged houses are still pending, not being rectified to date !
Damages appeared after IJM began construction works in 2014, like hill clearing, rock-blasting, piling and digging culvert at Trehaus site. As a result, sinkholes appeared, floods, waters seepage through multiple cracks on the ground, walls, tiles fallen from roofs and popped up from the ground due to vibration from rock-blasting and piling for the building.

The underground pipe leaked and waters seeped through the cracks!

Truths Be Told:
The truths be told, as echoed, reinforced and justified by recent events in Penang floods on 15th Sept 2017, Landslides in Tanjung Bungah on 21 October 2017, the storm on Nov 4 & 5 2017, floods again on Jan 5, 2018 …. see more on links to following reports:

We demand immediate enforcement & Actions:
1. The parties responsible must quickly without further delays, without condition to settle the claims and start the remedial works to the damaged houses, as both JPS has declared underground pipe culverts invalid and MBPP has issued stop work orders directed the developers, Worldwide Venture Sdn Bhd, a subsidiary of IJM Land to rectify the damages within 1 and 2 weeks time since 2015!
2. Enforce IJM’s & MBPP’ Letters/Stop-work Orders (attached in above), and divert waters from the two invalid underground pipe culverts deemed illegal at the IJM Trehaus site and nearby ponds which must be closed and grouted as a long term solution to the problems.
3. Enforce a fresh cease and desist to Stop Work of IJM Trehaus
construction project until the structural damages to house at 20
Lintang Bukit Jambul 1, BJ Cove have been resolved and settled the claim for damages and distress caused by the fear and danger of living in the house, without further delays and their suffering more than four years since 2014. Repairs and remedial works must start promptly as more damages and suffering will fellow!
4. Beef up the enforcement and accountability not just in government agencies but also in professional bodies, like the Board Of Engineers Malaysia (BEM), the Institute of Engineers Malaysia (IEM), etc to uphold the professional ethics, integrity and standards, to ensure public safety of the buildings and people life.
5. The pond must be made a Dried pond for waters to flow out smoothly, because there was originally two natural rivers/streams in the area where waters will still be running/seeping through naturally under the ground even if two culverts are closed as more waters are diverting from IJM Trehaus site to the pond.
Findings from Penang Forum
Dr Kam, a scientist, focused on expansion of impermeable surface area (caused by ill planned development and replacing natural ground cover such as hills, fields and trees that act as a water absorbing sponge) and soil erosion and landslides (caused by cutting and development in hill areas) as two factors that need special attention. She quoted Datuk Kam U Tee, the Penang Water Authority general manager (1973~90), as having correctly explained the Penang floods of October
2008, as follows: the floods were caused by conversion of the Paya Terubong and Bayan Baru valleys into “concrete aprons that do not retain water. The water immediately flows into streams causing flash floods even with moderate rainfall. Because of hillcutting activities, the flowing water causes erosion of the slopes which carries mud and silt into the river beds”. ( The Star, Oct 24, 2008).

Practise true CAT for Sustainable Development
Penang government must provide a COMPETENT flood mitigation plan for the state starting with a comprehensive Drainage Master Plan Study and not slogan.
The Penang government has to be ACCOUNTABLE to the people and not private developers. In other words, ‘Politicians should be ‘wakil rakyat’ and not ‘wakil pemaju’. If certain waterways and catchment areas have to be gazetted as permanent drainage and storage areas, then so be it.
The safety and well-being of the Rakyat has to come first. In the
interest of TRANSPARENCY, Penang has to launch an inquiry into how the local council approved property developments on slopes
without adequate slope protection.
