JKR Cawangan Kejuruteraan Cerun explained.

Why CKC was formed in 2004.

The JKR Slope Engineering Branch (Cawangan Kejuruteraan Cerun, CKC) was established in 2004 as a direct policy response to the Bukit Lanjan NKVE rockslide of December 2003. The Bukit Lanjan event involved approximately 35,000 cubic metres of rock failing onto the New Klang Valley Expressway near the Penchala Link interchange. There were no fatalities but the expressway was closed for over six months for emergency stabilisation, drainage works, and permanent slope treatment. The total cost was estimated at RM 836 million.

The federal-level response was that Malaysia required a dedicated slope engineering capability within JKR, distinct from general civil engineering, with the mandate to design, inspect, maintain, and respond on federal infrastructure slopes. CKC was the institutional answer. Within six years of its formation, the branch had produced the National Slope Master Plan (NSMP) 2009-2023 and the JKR Slope Engineering Manual 2010, two foundational documents that remain the primary federal references for Malaysian slope engineering.

What CKC does.

Documents you can actually pull.

What the slope register tracks.

The JKR SHaRp portal is the national federal-road slope inventory. As of November 2024 (the most recent publicly reported snapshot), SHaRp covers:

High-risk federal-road slopes. Of the 34,714 slopes monitored, 1,577 are classified as high-risk along federal roads. KKR (Ministry of Works) publicly reports the maintenance budget against this register through Parliamentary disclosures: RM 104.84 million was spent on repair works in 2024 (through September 2024), with RM 118 million allocated for 2025.

How to look up a specific slope. SHaRp is JKR-internal; the public-facing portal does not yet expose individual slope IDs to the lay user. To find the SHaRp classification of a specific federal-road slope adjacent to your property or project, submit a written request to the JKR district office (Cawangan Negeri) covering the area. Cite the road reference (e.g. FT1, FT2, FT5) and chainage or landmark. JKR district office confirms whether the slope is on the inventory, its risk class, and the current maintenance regime.

What SHaRp does not cover. State-road slopes (state government infrastructure), private-property slopes, hillside township internal road slopes, hillside development cut and fill slopes, hillside settlement catchments. These require separate engagement: state JKR for state roads, private commissioned engineering inspection for private property.

The maintenance hierarchy (distinct from JPBD planning class).

JKR CKC assigns each engineered cut or fill slope on federal infrastructure to a Class I-V maintenance hierarchy. This is distinct from the JPBD / PLANMalaysia Hillside Class I-IV planning classification (which applies to new development approvals based on slope angle). The two are often confused.

For property owners and JMB. If your property fronts a federal road, request the JKR Slope Class for the adjacent slope from the JKR district office. A Class I or II slope is maintained at higher priority by JKR (more frequent inspection, faster response, larger maintenance budget allocation). A Class IV or V slope receives lower-priority attention. Either way the property exposure to failure consequence does not change; the maintenance attention by JKR does.
