i2D Expands its Toolkit with the New E₄Cost Estimation Tool

E₄Cost is a valuable cost estimation tool for project planning, commercial assessments, and technical studies, delivering rapid, reliable results aligned with modern dredging project requirements.

Tool for Cost Estimation: E₄Cost

Accurate cost estimation is fundamental to the planning, delivery and evaluation of every dredging project. Productivity forecasting and cost modelling go hand in hand. Together, they form the basis for commercial decision-making, tender preparation, operational budgeting, project optimisation and even dispute resolution.

Recognising the importance of reliable, independent cost modelling, in2Dredging (i2D) took on the challenge of developing a modern, transparent and standardised tool. This tool is designed for estimating both Capital Expenditure (CAPEX) and Operational Expenditure (OPEX) across all types of dredging equipment.

The result is E₄Cost, a Python-based cost estimation engine grounded in international cost standards and i2D's established cost database.

What is E₄Cost

E₄Cost was designed to replace cumbersome traditional spreadsheets with a clean, efficient and consistent imput-output process. Its key advantages are detailed below.

Built on International Standards and Cost Databases

The tool ensures consistency and comparability across projects, clients and regions. It draws on an international cost database developed over more than a decade of in-house estimating.

Fast and Easy to Use

E₄Cost generates detailed, structured cost outputs without the need to navigate complex spreadsheets. Years of shadow estimating have provided clear insight into each cost component.

Highly Flexible

The tool supports a wide range of vessel and equipment types and can handle partial data through interpolation. This makes it suitable for conceptual studies, feasibility assessments, and dispute resolution proceedings, where accuracy and reliability are essential.

What Does E₄Cost Do?

E₄Cost combines international cost standards, equipment specifications, project-specific inputs and i2D's cost database to determine:

• Capital Costs - initial, replacement or residual value
• Operational expenditure, including:
• - Depreciation and interest
• - Maintenance and repair
• - Crew
• - Fuel or power
• Execution, mobilisation or standby costs
• Allowances for overheads, mark-ups and contingencies
• Transparent list of equipment used
• Complete project costs in any currency or for any project phase

The tool also includes an integrated currency-conversion system. This system allows global projects to model costs in local currency while easily modelling exchange rate fluctuations. Typical project cost bases include USD, EUR and local currency options.

E₄Cost Capabilities

E₄Cost can be applied across a wide range of dredging and marine construction projects. Once the project-specific vessel list and cost parameters are entered, the tool can assist with:

• Forecasting CAPEX and OPEX without market engagement
• Independently verifying contractor pricing
• Assessing the financial impact of design or methodology changes
• Conducting scenario and sensitivity analyses
• Quantifying claims or variations
