In the construction and business world, tenders can make or break a project. Choosing the right approach to cost estimation is critical — not just for accuracy, but also for building trust. One method that’s gaining traction is Cost-Plus Estimation.
What is Cost-Plus Estimation?
Cost-plus estimation is a pricing method where the contractor is reimbursed for actual project costs — such as labour, materials, equipment, and overheads — plus an agreed profit margin.
For clients: it offers transparency and confidence in how project funds are spent.
For contractors: it reduces the risk of underquoting and ensures fair compensation.
Why Use Cost-Plus in Tender Management?
Direct Costing Every dollar spent on materials, labour, and equipment is recorded and presented clearly.
Overheads Included Site and head office costs, insurances, and compliance expenses are built into the estimate.
Flexible Profit Margins Agreements can be structured as a fixed fee, a percentage, or with a guaranteed maximum price (GMP).
Risk Management Price escalations, supply chain disruptions, and project delays can be factored in upfront.
Transparency Sharing cost breakdowns helps build stronger client–contractor relationships.
