What is an EPC Contractor in Highway Construction?

An EPC contractor is responsible for executing a project from start to finish. In road construction projects, EPC contractors manage:

  • Engineering design of the highway
  • Procurement of construction materials
  • Project execution and site management
  • Quality control and safety compliance
  • Timely delivery of the project

This integrated model ensures quicker execution and better cost management for large infrastructure developments.

Biggest road construction companies by order book: the 2026 filings

The list above ranks what each company was building when it was compiled. A company’s own order book is the better measure of who will still be building highways next year, because it counts only the work left to do. Here are the latest figures published by the listed road builders, most of them names from the list above:

Company Order book as on Total order book (₹ crore) Roads and highways in it
GR Infraprojects 30 Jun 2026 25,319 70% (about ₹17,700 crore)
HG Infra Engineering 30 Jun 2026 14,502 ₹9,386 crore (65%)
Ashoka Buildcon 30 Jun 2026 15,251 ₹8,302 crore (54%)
PNC Infratech 30 Sep 2026 14,871 ₹8,197 crore (55%)
Dilip Buildcon 30 Jun 2026 27,691 17.1% (about ₹4,700 crore)
KNR Constructions 30 Jun 2026 8,667 ₹2,598 crore (30%)
IRB Infrastructure 30 Jun 2026 44,100 ₹1,700 crore of construction; the rest is highway operation and maintenance
Larsen & Toubro 30 Sep 2026 8,53,514 Not published separately

Two things stand out. Among the companies that publish a roads figure, GR Infraprojects has the largest road construction book by a wide margin, and Dilip Buildcon, at the top of the March list, now earns most of its order book outside roads. IRB’s ₹42,400 crore of operation and maintenance work is on highways too, but it is toll-road upkeep rather than new construction, which is what pulls in excavators, graders and compactors.

PNC Infratech’s filing also records that NHAI extended a three-year debarment to the company on 11 September 2026, and that the Delhi High Court stayed the effect of the debarment orders on 12 October 2026. The background is in what the PNC Infratech NHAI debarment means.

Major Highway Mega Projects Under Construction

Delhi Mumbai Expressway under construction India

Delhi-Mumbai Expressway

The Delhi-Mumbai Expressway is one of India’s largest infrastructure projects. Once finished, it will greatly reduce travel time between Delhi and Mumbai while improving freight movement nationwide.

Multiple EPC contractors are handling different packages of the expressway.

Ganga Expressway

The Ganga Expressway is a significant project connecting multiple cities across Uttar Pradesh. It will enhance road connectivity and support industrial and economic growth in the area.

The 594-km expressway from Meerut to Prayagraj was inaugurated on 29 April 2026, and Uttar Pradesh has since approved an extension towards Haridwar.

Bengaluru-Chennai Expressway

This expressway will improve connectivity between Bengaluru and Chennai, two major industrial and technology hubs in South India.

Mumbai Coastal Road

The Mumbai Coastal Road project is a key urban infrastructure development aimed at reducing congestion and improving coastal connectivity within the city.

Construction Equipment Powering Highway Projects

Highway construction requires modern machinery to manage large-scale earthmoving, road leveling, material handling, and concrete work.

Below are the most commonly used construction machines in highway projects.

Excavators

Excavators are used for earthmoving, digging, trenching, and site preparation in highway construction. They are essential for infrastructure development.

Backhoe Loaders

Backhoe loaders are versatile machines that combine the functions of an excavator and a loader. They are widely used for:

  • Trenching
  • Digging
  • Loading materials
  • Small-scale excavation

Due to their flexibility and cost-effectiveness, backhoe loaders are commonly used in highway and infrastructure projects.

The most familiar on Indian highway sites, the JCB 3DX, is listed at ₹30–32 lakh (October 2026).

Motor Graders

Motor graders are crucial for road leveling, slope shaping, and surface finishing. They help achieve smooth road surfaces before asphalt or concrete is laid.

Concrete Mixers

Concrete mixers are used to mix cement, sand, aggregates, and water to produce concrete needed for road foundations, culverts, bridges, and drainage structures.

They ensure consistent concrete quality and faster construction progress.

Concrete Pumps

Concrete pumps enable efficient transportation and placement of concrete across large construction sites, particularly in areas where direct pouring is difficult.

Hydra Cranes

Hydra cranes are commonly used in infrastructure projects for lifting heavy materials, moving equipment, and handling structural elements.

Compactors

Compactors are essential in road construction, compressing soil layers to enhance stability and durability of highways.

Construction Equipment Demand in Highway Projects

With highway projects worth ₹3.36 lakh crore underway in the March 2026 list, demand for construction machinery in India is increasing rapidly.

The build rate backs that up. NHAI alone constructed 5,313 km of national highways in 2025-26, about 15% more than its target of 4,640 km, and spent ₹2,44,362 crore on national highway development in the year, according to its press release of 1 April 2026.

EPC contractors need reliable and efficient equipment to maintain productivity and meet tight project schedules. Consequently, the demand for the following machines continues to rise:

  • Excavators
  • Backhoe Loaders
  • Motor Graders
  • Concrete Mixers
  • Concrete Pumps
  • Hydra Cranes
  • Compactors

This infrastructure boom is expected to drive strong growth in the construction equipment industry over the next decade. If you are sizing a machine against that pipeline, compare models on the comparison pages and line up funding on the equipment finance page before you commit. The road construction machinery page puts the models, live highway tenders and contractor news in one place.

Impact on India’s Infrastructure Growth

The development of expressways and national highways is vital for economic growth. Improved road infrastructure helps:

  • Reduce travel time
  • Improve freight logistics
  • Boost regional connectivity
  • Support industrial and economic development

The role of EPC contractors is therefore crucial in shaping the future of India’s infrastructure landscape.

Which EPC companies are building India highways?

India’s highway construction sector is entering a new phase of large-scale infrastructure development. Leading EPC contractors are working on massive projects that will reshape the country’s transportation network.

These companies are building roads and expressways, and creating strong demand for modern construction equipment such as excavators, backhoe loaders, motor graders, concrete mixers, and cranes.

As infrastructure investments keep growing, the partnership between EPC companies and construction equipment providers will be key to accelerating India’s development.
