Applies to precast and post‑tensioned concrete elements. It includes requirements for tendons, sheathing, grouting, stressing sequence and quality control.
The (JKR 20800-0226-20) is a comprehensive technical document issued by Jabatan Kerja Raya Malaysia to establish uniform standards for materials and workmanship in building construction projects. Key Features and Improvements
Procedures for clearing, grubbing, and handling different soil types, including "Hard Mass" and "Rock Mass".
One of the most detailed sections, it regulates cement, aggregates, water, admixtures, concrete mix design, production, transport, placing, compaction, curing, formwork, reinforcement, joints and quality control. JKR permits the use of various cementitious materials (CEM I, GGBS, PFA, silica fume) and requires aggregates to comply with MS 30 and EN 12620. The standard also specifies minimum compressive strength for lightweight foam concrete (2.8 N/mm² for hollow blocks). standard specification for building works 2020 jkr pdf
In addition to safety, sustainability is a growing focus. The global construction industry is a major contributor to carbon emissions, and the 2020 specification acknowledges this challenge. It introduces guidelines for the use of sustainable materials and waste management on-site. For instance, specifications regarding the sourcing of timber (requiring certified sources) and the use of recycled content in building materials help align public projects with Malaysia’s green building aspirations, such as the Green Building Index (GBI) requirements.
The JKR Standard Specification undergoes periodic revisions to align with technological advancements, safety regulations, and modern environmental standards.
Sets out the types of reinforcement bars (e.g., MS 146, BS 4449), bending schedules, lapping, tying, cover tolerances and field bending requirements. Applies to precast and post‑tensioned concrete elements
It provides a uniform standard for tender and contract affairs across all government projects.
The 2020 specification is not just a list of requirements; it is an active tool for quality control. JKR site supervisors use "Nota Semakan Pembinaan dan Penyeliaan Tapak Bina" (Site Construction and Supervision Review Notes) to conduct inspections, referencing the standard's clauses to verify compliance on every project.
Requirements for progress photographs and as-built drawings. Setting out the works and establishing benchmarks. Section B: Excavation and Earthworks The standard also specifies minimum compressive strength for
