Trinity Group Sdn Bhd, developer of The Z Residence condominium project in Bukit Jalil, Kuala Lumpur, will take steps to ease concerns raised by residents of the nearby Bukit OUG Condominium over the impact of the project's construction.

In the past month, the residents have raised concerns over a number of high-rise developments in their midst, saying the various high-density projects in the neighbourhood would worsen traffic congestion there.

They also raised concerns over the hillside projects citing fears of landslides akin to the Bukit Antarabangsa tragedy in 2008 where five people were killed and 15 bungalows destroyed. Apart from Trinity Group's The Z Residence, other projects in the area are Exsim Development Sdn Bhd unnamed four-block condo development and Kiara Resources Sdn Bhd's Kiara Residency.

Trinity Group's project will comprise four blocks, each over 20 storeys, housing 1,136 units to be built on a seven-acre (2.8ha) freehold site while both phases of Kiara Residency will contain a total of 1,060 units built on five acres of leasehold land.

Trinity Group managing director Dato’ Neoh Soo Keat said among the measures, the developer will build a new road which is the "missing link" between Jalan BK 1/20 and Jalan 4/155 to avoid future traffic congestion and take steps to reduce construction pollution.

 "The new 800m road access will cost RM3 million;' Neoh told reporters at a briefing yesterday. The new road is expected to allow passage of larger vehicles and shorten the travelling distance from Puchong to Bukit Jalil via the Bukit Jalil highway, he added.

Neoh said Trinity Group would cut the sandstone slope gradually, one metre at a time until it is lowered from its current 23.5 metres to nine, to improve slope stability.

"It's generally a stable slope because it's a rock formation;' he said. The Z Residence's platform will also be lowered to the same level as Bukit OUG Condominium, he added.

The project's civil and structural consulting engineer Jurutera Perunding Alphareka Sdn Bhd director Looi Koon Chew said the slope will be cut inwards so that any loose soil will fall into the project's compound.

Trinity Group also plans to ask for permission from residents to set up hoardings in Bukit OUG Condominium's parking lot bordering its project to trap any debris from the slope-cutting exercise, said Neoh. Lastly, it will also impose measures to control water and air pollution from its project and expects to reduce pollution by 70% to 80%, he added.

"We have slowed down our earthworks and have started ground protection;' he said. Neoh also said DBKL would reveal the Public Works Institute of Malaysia (Ikram) report on the slope's integrity to residents and the media on July 27.
