Quick answer
The Ministry of Road Transport and Highways' technical specifications governing materials, construction methods, and quality standards for all national highway and road projects in India.
MoRTH Specifications refers to the technical specifications document published by the Ministry of Road Transport and Highways (MoRTH) that governs the materials, construction methods, workmanship standards, and quality acceptance criteria for all highway and road construction work in India. The current version is the 6th revision, which is the mandatory reference for all NHAI, BRO, and state highway projects funded through central schemes.
What are MoRTH Specifications in government procurement?
The MoRTH Specifications, formally titled "Specifications for Road and Bridge Works," is a comprehensive document of over 1,200 items covering every aspect of road construction: earthwork and subgrade, granular sub-base (GSB), base and surface course (WMM, DBM, BC), bridges and culverts, retaining structures, drainage, road furniture, and highway safety systems.
Each specification item defines: the materials required (with reference to relevant IS codes and IRC standards), construction methodology and equipment requirements, quality control tests to be performed, frequencies of testing, acceptance criteria, and the measurement unit for BOQ payment.
Road construction BOQs are priced using MoRTH item numbers, each BOQ item references a specific MoRTH specification number. The contractor is obliged to follow that specification for the referenced item regardless of what simpler or cheaper alternative might be commercially available. Site engineers test compliance against MoRTH acceptance criteria, and non-compliant work is rejected.
The MoRTH Standard Data Book (SDB), published alongside the specifications, provides the material, labour, and equipment consumption norms for each item, the building blocks for rate analysis. Combined with current market rates for materials and labour, the SDB enables calculation of realistic unit rates for BOQ pricing.
MoRTH specifications are referenced by NHAI in all its EPC, HAM, and O&M contracts. State highways funded under the Pradhan Mantri Gram Sadak Yojana (PMGSY) and NABARD rural roads schemes also mandate MoRTH specification compliance, making this the dominant technical standard for road works across India.
Why it matters for bidders
Road construction contractors must be completely familiar with MoRTH specifications before pricing any highway BOQ. Each specification item imposes material standards (quality and source approval requirements for aggregates, bitumen grade, cement), equipment requirements (specific machinery types that affect operating costs), and testing frequencies (each test has a cost, particularly for lab testing like Marshall mix design, CBR testing, and core cutting).
Pricing errors caused by using wrong material specifications, for example, assuming DBM Layer 1 uses 60-70 grade bitumen when the MoRTH specification for that road type requires PMB-40, can turn a profitable contract into a loss-maker. The difference in bitumen cost alone can be Rs 8,000-12,000 per tonne between grades.
Quality failures against MoRTH acceptance criteria result in rejection of executed work and mandatory redo at contractor's cost. Quality-related cost risk is therefore significant and must be factored into bidding margins.
Example
An NHAI EPC contract for a 4-lane highway in Maharashtra specifies the bituminous course as Dense Bituminous Macadam (DBM) per MoRTH Specification Clause 507. The contractor's rate analysis uses the SDB labour and plant norms for DBM: 2.52 MT bitumen at PMB-40 grade per 100 sqm per 50mm layer, calculated at the IOC current PMB-40 price. Lab testing for mix design (Marshall Stability Test) adds Rs 15,000 per mix design submission. The QC protocol requires one core per 500 sqm for density. The contractor prices each component, material, plant, labour, testing, to arrive at the BOQ unit rate per sqm for DBM Layer 1.
Key rules / thresholds
- The current controlling document is MoRTH Specifications for Road and Bridge Works, 6th Revision.
- Every BOQ item in NHAI and central scheme highway tenders references a MoRTH specification clause.
- The MoRTH Standard Data Book (SDB) provides consumption norms for rate analysis, currently updated annually.
- Non-compliance with acceptance criteria (density, gradation, stability, smoothness) results in rejection and mandatory remediation.
- Contractors must get aggregate and bitumen sources approved by the employer's engineer before commencement per MoRTH Clause 900 (Quality Control).
