## What is Construction Costs?

The App is a tool for the property and construction industry providing a database and calculator to facilitate project planning, cost and value benchmarking in Ireland.

Gives construction and development cost database for a broad range of project types with international cost indices for benchmarking purposes. Calculator allows estimation of total construction cost, construction inflation and finance costs for projects. Benchmarking v Market tool allows benchmarking of an inputed initial cost estimate versus expected market construction costs. Costs are calculated forecasts and not based on returned historical data.

The embodied carbon content range for new buildings is estimated using published data (kg CO2e/m2) for different building types. Source IGBC.

Revenue, rental rates and exit yield ranges for a range of building types are collated from publicly available data, annual financial statements of listed companies & transaction data. A calculator allows estimation of value based on user defined inputs and assumptions.

Costs, rental ranges and yields are based H1 2025.

Inflation calculation (and index) is based on average cost for the project and calculated internal Keogh Consulting tender inflation forecast - this can be used to estimate contingency for extended programmes.

Finance cost estimates takes a s-curve construction cashflow and calculates rolled up interest based on monthly interest charge in arrears on average current loan balance.
