Callidus

What Callidus does

Callidus India Private Limited is a New Delhi-headquartered professional services firm providing Quantity Surveying (QS) and Construction Cost Management services to the construction industry. The company serves four primary customer segments: Developers/Project Owners, Subcontractors, General Contractors, and Consulting firms, delivering services across project lifecycle stages from inception to final completion. Its core service portfolio comprises three interconnected offerings: Pre-Contract QS (cost planning and Bills of Quantities preparation), Post-Contract QS (interim valuations, change management, contract administration, and final account settlement), and Construction Cost Management (end-to-end cost oversight for civil, structural, architectural, interiors, MEP, utilities, and infrastructure projects across both new builds and refurbishments).

The firm's technical foundation rests on industry-standard QS and CAD tooling — AutoCAD, CostX, On-Screen Take-off (OST), and the MS-Office suite — combined with deep expertise in multiple international measurement codes including POMI, QSMM, SMM7, NRM 1 & 2, CESMM4, ARM4, IS 1200, and Australian SMM. This cross-jurisdictional code expertise enables the firm to deliver quantity takeoffs and cost management services across US, UK, Ireland, Australia, Middle East, and Southeast Asia markets. The company maintains a registered office and corporate office in New Delhi, plus an international office in Panania NSW, Australia, supporting both offshore and onshore (on-site measurement support/secondment) delivery models.

Callidus operates as a bootstrapped, privately held company that emerged from mentor Intec Infra Technologies Pvt. Ltd., carrying with it more than a decade of QS service experience. Revenue is generated through professional services engagements on a project or retainer basis, though specific pricing is not publicly disclosed. The firm has no external institutional investors, no disclosed funding rounds, no patents, and no proprietary technology platform — its value proposition is grounded in human expertise, cross-geography delivery capability, and domain specialization rather than technology differentiation.

• Gleeds: International construction and property consultancy with core cost management and quantity surveying practices. Comparable in lifecycle QS coverage and multi-region delivery model.
• Linesight: Specialist cost management and project controls consultancy with strong data center and infrastructure focus. Comparable as a specialist QS/cost consultancy serving construction sector clients across multiple jurisdictions.
• WT Partnership: International cost management consultancy delivering quantity surveying services to construction clients. Comparable in service specialization and cross-border delivery, particularly relevant given Callidus's Australia presence.
• Faithful+Gould (AtkinsRéalis): Cost management and project controls consultancy within AtkinsRéalis. Comparable QS and cost advisory offering for developers and contractors, though bundled within a much larger engineering services group.

Broad incumbents

• Arcadis: Global design, engineering, and consultancy firm with a significant cost management practice (formerly EC Harris). Overlaps Callidus on cost consultancy work but offers a much wider portfolio of services.
• AECOM: Global infrastructure consulting firm with cost management capability inherited from Davis Langdon. Adjacent competitor on large QS mandates but not a specialist cost management firm.
• Mott MacDonald: Multidisciplinary engineering, management, and development consultancy with a cost management practice. Comparable on construction cost consultancy work for major projects, though within a broader engineering portfolio.
