Earthworks standards specify the methods for site clearing, excavation depths, soil testing, and compaction. It details the classification of excavated materials (such as rock versus soft material) and outlines requirements for anti-termite treatments prior to laying foundations. Concrete Works

Often hosted within national construction databases for construction professionals.

The is the definitive technical reference published by Jabatan Kerja Raya (JKR) Malaysia to ensure uniformity, safety, and high-quality workmanship in government construction projects . Replacing the earlier 2014 edition, this document incorporates updated international standards, modern construction technologies, and revised government policies, including a stronger focus on sustainable development.

Covers the design, materials, installation, testing and acceptance criteria for driven piles, bored piles and other foundation elements. The section includes specific tolerances, concrete cover requirements and methods for underwater concreting (e.g., use of a tremie). It also specifies load testing regimes: for pile load tests, the standard requires testing of 1% of total pile points or two numbers per pile size/pile type, whichever is higher.

The specification directly influences the Bills of Quantities (BQ). A QS must read the JKR specification in tandem with the Standard Method of Measurement (SMM) to ensure that the descriptions of items in the BQ accurately reflect the quality and methodology demanded by JKR. 2.

Provides requirements for shallow foundations, including pad footings and strip footings. It is used in conjunction with Section C (Foundation Works) of the JKR Standard Specification for Road Works.

The specification is vast, covering nearly every aspect of building construction, including:

Greater focus on energy-efficient materials and sustainable construction practices.

The 2020 standard brings significant improvements over its predecessors (such as the 2005 version):
