Forecasting project financials for a construction project is a critical task that requires careful planning and analysis. Accurate forecasting helps project and development managers and stakeholders to make informed decisions, identify potential risks, and ensure the project stays within budget. Below are common mistakes to avoid and steps to effectively forecast project financials for a construction project.

Common Mistakes When Forecasting Project Financials

Forecasting construction project financials can tend to be complex, and several common mistakes can occur during the process. Here are some of the most common mistakes or issues that can occur:

  • Underestimating Costs: If you fail to accurately estimate the costs of materials, equipment, labor and other expenses; it can lead to budget overruns. It's essential to account for all possible costs for the project, including unforeseen events.

  • Ignoring Contingencies: Not including contingency reserves in your budget can leave the project vulnerable to unexpected expenses. Contingencies are essential to mitigate risks and uncertainties, as well as to accurately forecast the project financials.

  • Overlooking Scope Changes: Changes in the project’s scope can significantly impact financials! Failure to anticipate and account for these scope changes can lead to cost overruns, in addition to schedule delays.

  • Not Considering Market Trends: Stay informed. By ignoring market trends and inflation; your project may result in inaccurate forecasting. It's crucial to stay updated on market conditions and adjust forecasts accordingly.

  • Lack of Communication: One of the most essential tasks for project forecasting can sometimes be the least-used. Poor communication among project stakeholders can lead to misunderstandings and frustration when working through a project. That’s why it's essential to ensure all stakeholders are informed and engaged in project forecasting.

  • Relying on Incomplete or Outdated Data: Using incomplete or outdated data for cost estimates can result in inaccurate forecasts for a project. Therefore, it's critically important to use reliable and up-to-date information for more accurate projections.

  • Overestimating Revenue: A ‘blue-sky’ forecast is what all companies and projects aspire to have; but being overly optimistic about revenue projections can lead to unrealistic financial forecasts. It's essential to base your project revenue estimates on realistic assumptions, as well as market conditions.

  • Not Monitoring Progress: During the life of a project, failing to monitor progress against the forecast can lead to cost overruns and schedule delays. It’s important to engage in regular monitoring and adjustments to keep your project and projections on track.

Best Practices in Forecasting Project Financials

Forecasting project financials and cash flows for your construction projects is a critical task that requires careful planning and analysis. Accurate forecasting helps project managers and stakeholders make informed decisions on the project, identify potential risks that may occur, and ensure the project stays within the specified budget. Here are steps to help you effectively forecast project financials for a construction project:

  • Learn from Past Projects: Your first step in the process is to take time to review past projects. Identify what worked well and what didn't, and use this knowledge to improve your forecasting process for future projects.

  • Develop a Cash Flow Forecast: Create a detailed cash flow forecast that outlines the expected inflows and outflows of cash over the project's duration. It’s useful to consider factors such as project costs, funding sources, payment schedules, and revenue projections.

  • Estimate Cash Inflows: Identify all sources of cash inflows for the project, including financing, equity investments, customer payments, and government incentives. Then estimate the timing and amount of these inflows based on contractual agreements and project milestones.

  • Plan Cash Outflows: Determine the timing and amount of cash outflows for expenses such as construction costs, subcontractor payments, material purchases, equipment rentals, permits, taxes, and overheads. Then you are able to align cash outflows with the project schedule and budget.

  • Manage Working Capital: Maintain adequate working capital to cover day-to-day operating expenses, unexpected costs, and fluctuations in cash flow. Monitor inventory levels, accounts receivable, and accounts payable to optimize working capital management.

  • Negotiate Payment Terms: Aim to negotiate favorable payment terms with suppliers, subcontractors, and vendors to optimize your cash flow management. You can consider options such as milestone-based payments, extended payment terms, early payment discounts, and installment plans.

  • Document Agreements & Decisions: Document any agreements or decisions related to the cash flow projections in formal contracts or agreements with your equity and debt partners. Clearly outline roles, responsibilities, expectations, and terms of collaboration to avoid misunderstandings or disputes later on.

  • Monitor Cash Flow Regularly: Track cash flows regularly to monitor actual versus projected cash inflows and outflows. Use cash flow statements, financial reports, and accounting software to analyze cash flow trends, identify variances, and make informed decisions.

  • Forecast and Plan for Variability: You should anticipate and plan for variability in cash flows due to several factors, including project delays, cost overruns, change orders, weather disruptions, and economic fluctuations. You may also need to conduct sensitivity analysis and scenario planning to assess the impact of potential changes on cash flow. It’s also important to account for inflation and current market trends when estimating costs for materials, labor, and equipment. Prices can fluctuate over time, impacting project expenses.

  • Implement Cash Flow Controls: Implement controls and procedures to manage cash flow effectively, such as approval processes for expenses, budget monitoring, expense tracking, cash reserves, and cash flow forecasting updates.

  • Optimize Cash Flow Timing: Optimize the timing of cash flows by aligning payments with project milestones, maximizing cash inflows, and minimizing cash outflows during periods of low activity or downtime.

  • Monitoring and Adjustments: Review and adjust your financial forecast regularly as the project progresses. Compare actual costs and revenues with your forecast to identify any discrepancies and make necessary adjustments. As the project progresses, update your forecasts regularly to reflect any changes in scope, costs, or timelines. This will help you make informed decisions and keep the project on track.

  • Reporting and Communication: Provide your equity and debt partners with detailed documentation of the cash flow projections. This may include financial reports, charts, graphs, and explanatory notes to help them understand the assumptions and calculations behind the projections. Maintain open communication channels to address any concerns or changes, and involve key stakeholders in the forecasting process to gather insights and ensure alignment with project goals. Their input can provide valuable perspectives on potential costs and revenue streams. Schedule regular meetings or updates with your equity and debt partners to review the cash flow projections. Discuss any changes, updates, or deviations from the initial projections and ensure transparency in communication.

  • Use Financial Modeling Tools: Finally, consider using project management software or tools that can help streamline the forecasting process. These tools can help you track expenses, manage resources, and generate reports to monitor financial performance. Rabbet offers a robust set of budgeting and forecasting tools that will help you accomplish this goal easily! These tools can automate calculations, generate reports, and provide real-time insights into project finances.

Forecasting Project Financials in Rabbet

Rabbet provides budget management tools to both monitor internal forecasts and make changes that are shared externally in the draw package. Rabbet can assist this process by being used to monitor the project budget at the various stages of cost realization. Its intuitive tools give you stronger insight into your project finances to ensure that a project remains on time and on budget. Some of the tools and reporting include:

  • Agreements & Committed Costs: Whenever a vendor agreement is recorded in your project, the agreement amount is considered a 'committed' cost on the applicable line item. The 'committed' costs can also be viewed on the Project Overview tab. The budget table view compares the budget amount for a line item to the most probable costs (committed costs) based on agreements.

  • Track Costs to Agreements: In addition to comparing agreements to the budget for tracking buyout and anticipated budget, customers on the Premium tier are now able to track costs to specific agreements. This article walks through how to seamlessly track all invoices and pay applications against contracts and executed change orders so that you can confirm invoices are within contract, and understand how much is remaining in contract and in budget.

  • Tracking Exposures in your Budget: During the life of your project, events will happen that eventually result in change orders or executed budget reallocations. These events typically occur outside the original construction contract or vendor agreement. Examples of these events include:

    • Increased architecture fees due to a redesign

    • Unexpected soil conditions while excavating

    • Additional financing costs

Utilize Anticipated Cost Reporting

Rabbet's default "Anticipated Cost Report" view has a number of columns available that will allow you to forecast your project's anticipated costs across the life of the job.

The Anticipated Cost Report includes default columns available for your use:

  • Committed

  • Uncommitted

  • PCOs & Exposures

  • Out of Contract

  • Anticipated Budget

  • Budget Overages

  • Anticipated Expenditures

  • Expenditure Overages

In addition to these default columns, Rabbet allows you to add additional applicable ACR columns into your own customized view.

Create a Projection Using Rabbet’s Projections Feature

After a budget has been added to Rabbet during project creation, utilize the Projections feature to forecast the timing of the costs. This tool provides a mechanism for setting spending parameters that simplify the projection process and provide clear cost visualizations. When funding sources are configured for a project, the Projections tab will also outline the funding breakdown of the cost projection. Rabbet will alert you to insufficient funds based on the line items budgeted amounts and funding source configurations. These alerts outline discrepancies at both the project and single funding source level. You may also refer to this article on Actuals and Budget Updates for Projections to see how Rabbet can further enhance your cash flow projections.
