Construction and infrastructure: Value chain, from upstream to the customer
Contractors building roads, rail, ports, power and water networks and buildings
Value chain, from upstream to the customer
Criticality to the chain: 5 · Chokepoint 4 · Critical 3 · Important 2 · Supporting 1 · Commodity service Stage 1 Project sponsorship and financePlan projects, acquire land, award contracts and pay for most infrastructure, either from budgets or through public-private partnerships.2
Why critical: Each agency is the only buyer for its network, so slow approvals, land acquisition or payment delays stall whole programmes. Technologies National infrastructure pipelines PPP and hybrid-annuity models Land-acquisition processes PM Gati Shakti GIS planning Depends on Industries Public administration, defence and securityFinance: banking, insurance, marketsExamples: National Highways Authority of India, Indian Railways (RVNL), National Capital Region Transport Corporation, National Highways (UK)Provide long-tenor loans, guarantees and equity for projects and buy completed assets to recycle capital.
Why critical: Few lenders can take 15-25 year infrastructure risk, so tighter credit quickly delays financial closure. Technologies Project finance and non-recourse lending Infrastructure investment trusts Green and infrastructure bonds Credit enhancement Depends on Industries Finance: banking, insurance, marketsExamples: NaBFID, Power Finance Corporation, State Bank of India, World Bank, BrookfieldSurvey sites, prepare detailed project reports and designs, and supervise construction quality for owners.
Why important: Many firms compete, but poor DPRs cause redesign and delays, and changing designer mid-project is costly. Technologies Building information modelling (BIM) Geotechnical investigation Structural analysis software Drone and LiDAR survey Depends on Energy Bld Energy in buildings Industries Professional servicesSoftware and IT servicesExamples: AECOM, Arup, RITES, Tata Consulting EngineersQuarry stone and sand, make cement and deliver ready-mix concrete to sites, usually within a few hundred kilometres.
Why important: Several producers serve each region, but haul distances make supply local and prices move with regional consolidation. Technologies Dry-process kilns with preheaters Blended cements with fly ash and slag Ready-mix batching Waste-heat recovery Depends on Commodities Cem CementCaO LimeGyp GypsumAgg Sand & gravelStn Crushed stone Chemicals Con Construction chemicals Energy Tc Thermal coalWHR Waste-heat power (steam Rankine)HI Energy-intensive industry Industries Building materialsExamples: UltraTech Cement, Ambuja Cements, Holcim, Heidelberg MaterialsMake reinforcing bars, beams, plates and pipes for concrete, bridges and buildings.
Why important: Many integrated and secondary mills compete, but steel prices swing with Chinese exports and import duties. Technologies Blast furnace and electric arc furnace TMT rebar rolling Structural sections Pre-engineered buildings Depends on Commodities St SteelFe Iron oreMn ManganeseV Vanadium Chemicals O2 Oxygen Energy Kc Coking coalCDQ Steel plant energy recovery Industries Metal productsExamples: JSW Steel, Tata Steel, Steel Authority of India, ArcelorMittalSupply formwork timber, plywood, pipes, glass, waterproofing, paint and fittings for structures and buildings.
Why supporting: Competitive supply with many brands; substitution within weeks. Technologies Engineered wood and plywood PVC and HDPE pipes Float glass Waterproofing membranes Depends on Commodities Tm TimberQz Silica sand Chemicals PVC PVCHDPE High-density polyethylenePnt Paints and coatingsAdh Adhesives and sealants Energy Gas Natural gas Industries Wood productsPlastic and rubber productsExamples: Pidilite Industries, Saint-Gobain, Supreme Industries, Century PlyboardsSupply and rent excavators, cranes, pavers, piling rigs and tunnel-boring machines, often with operators.
Why critical: Ordinary earthmovers are plentiful, but tunnel-boring machines and very large cranes come from a few makers (Herrenknecht, CRCHI, Liebherr) and are built to order, so a delayed machine holds up a whole tunnel or bridge. Technologies Hydraulic excavators Tower and crawler cranes Tunnel-boring machines Machine telematics Depends on Commodities St Steel Chemicals Lub Lubricant additives Energy ICE Internal combustion engines and gensetsOil Crude oil Industries Machinery and equipmentExamples: Caterpillar, Herrenknecht, Liebherr, JCB India, Sanghvi MoversTake responsibility for building a project to time and budget, managing subcontractors, materials and labour.
Why critical: Only a few firms can qualify for the largest metro, bridge and power packages, and replacing a failed contractor costs years. Technologies Precast and modular construction Slip-form and segmental bridge launching Project scheduling and BIM Mechanised tunnelling Depends on Commodities Cem CementSt SteelAgg Sand & gravelCu Copper Chemicals Con Construction chemicalsEPX Epoxy resins Energy ICE Internal combustion engines and gensetsDist Distribution grids, mini-grids and interconnectors Industries Building materialsMachinery and equipmentWater and sanitationExamples: Larsen & Toubro, Afcons Infrastructure, China State Construction Engineering, Vinci, BechtelInstall foundations, building services, electrical systems, lifts and facades under the main contractor.
Why important: Many firms exist, but skilled crews are scarce in a boom and switching mid-job causes rework. Technologies Mechanical, electrical and plumbing systems Bored piling System formwork Unitised curtain walls Depends on Commodities Cu CopperAl AluminiumSt Steel Chemicals PVC PVCPU Polyurethanes (MDI, TDI, polyols) Energy HP Heat pumps, air conditioning and refrigeration Industries Electrical equipmentMetal productsExamples: Voltas, Sterling and Wilson, Doka, Peri, OtisSupply masons, bar-benders, carpenters and general labour to sites, often migrant workers hired through intermediaries.
Why supporting: Labour is plentiful in India but seasonal and poorly skilled, so shortages at harvest or festivals slow work for weeks. Technologies Skill certification Digital attendance and wage payment Site safety equipment Depends on Energy Mu Muscle power Industries Education and researchExamples: Quess Corp, TeamLease ServicesRun and maintain completed roads, transmission lines, ports and pipelines, collecting tolls or annuities for decades.
Why important: Several operators bid for concessions, but each asset has one operator and contracts run 15-30 years. Technologies Electronic toll collection (FASTag) Asset-management systems Remote monitoring Pavement and structural inspection Depends on Commodities Oil Crude oil Chemicals Pnt Paints and coatings Energy Dist Distribution grids, mini-grids and interconnectors Industries Transport and logisticsFinance: banking, insurance, marketsExamples: IRB Infrastructure Developers, PowerGrid InvIT, Adani Ports, Transurban
