How Do We Deliver Accurate Estimates?
From Plan Review to Final Estimate
- Our process is designed to make sure that your estimate is thorough and accurate. Here’s how we do it:
- Initial Document Analysis: First, we go through the documents you give us, such as project plans, blueprints, and sketches. These give us an idea of what has to be done.
- Research & Data Collection: We then gather the latest information on material costs, labor, and any other variable that may impact the project.
- Cost Calculation: We calculate the costs for each element of the project once we have all the details.
- Final Estimate Delivery: Lastly, we present you with a precise and accurate estimate so that you can make decisions based on credible numbers.
- Attention to Detail: We focus on every part of the project to make sure we don’t miss anything.
- Using the Right Data: We use the best and most recent data to create an accurate estimate.
- Clear Communication: We break the estimate down into easy-to-understand sections, so you know where your money is going.
Data and Plans to Create Your Estimate
Accuracy always depends on the data we will be using, and an example of that would be having current cost data plus project documents given by you for the best possible estimate. We first take your blueprints and sketches detailing all that information concerning your project layout, design, and material.
- Project Documents: We also look at other documents, such as specifications and technical drawings, to ensure that we do not miss any details.
- Cost Data: We gather the most current information on the costs of materials, labor, and any other necessary expenses from trusted sources.
- Local and National Cost Factors: We consider the local and national market conditions. This may include material and labor costs in your area so that your estimate will be realistic.

Detailed Breakdown of Your Estimate
When we give you your estimate, you’ll get a clear breakdown of all of the costs. We want to make sure you understand each part of your project, so provide the following:
- Material Costs: We break down all of your material needs for this project, from simple, basic items to highly technical pieces of equipment.
- Labor Expenses: We break down labor costs, including skilled workers, general labor, and subcontractors that you may require.
- Equipment Costs: When your project has equipment requirements, we incorporate them in the quotation rental or the outright purchase of the machinery.
- Contingency: An amount is put as contingency due to unaccounted costs that might arise on a project
- Other Costs: Any costs have been included, such as insurance, or project management charges.
Types of Estimates We Deliver
We provide you with different types of conceptual estimates depending on the level of detail and accuracy you need for your project. Here’s a preview of each:
Rough Estimate
- Accuracy Range: -50% to +50% of actual cost.
- Best for: The early stages of your project, where you only need a general idea of the costs.
- Details: This is the least accurate estimate. It gives you a rough range of the potential costs. Good for early planning.
Ballpark Estimate
- Accuracy Range: -20% to +20% of the actual cost.
- Best for: Projects still in the planning phase and need a more accurate prediction.
- Details: This estimate uses more refined data to give you a better idea of the project costs.
Budget Estimate
- Precision Range: ±10% to +25% of actual cost.
- Suitable for: Project contractors at the end of a project who require an accurate estimate of costs.
- Information: This estimate would be much more detailed and nearer to actual costs, which represent the significant cost elements of a project.
Preliminary Estimate
- Precision Range: Error margin: ±10% to ±15%
- Suitable for: Early project phases with partial design data available.
- Information: It gives a clearer cost estimate than a conceptual one.
Definitive Estimate
- Precision Range: ±5% to +15% of actual cost.
- Suitable for: Contractors who require the most accurate estimate before submitting their bid.
- Information: This is the most accurate estimate and provides you with an extremely close approximation of the costs.
- Each of these estimates is built to support your needs in different phases of your project planning and bidding cycle.

Detailed Deliverables
In our estimates, we list everything that will be needed for the project. There are the preliminaries to get things off to a good start, and of course, these substructures are the footings and foundations that comprise the base of the building. The superstructure includes the brickwork, walls, roofs, and floors and everything derived from those, and finally, finishes both exterior and interior, including flooring, drywall, painting, fittings, and mechanical systems like HVAC and ductwork. Plumbing is part of the estimate, along with pipes, drains, and fixtures.
We also include electrical work such as cables, conduits, and lighting. Our estimate includes labor costs and man hours required to complete the work. We include a contingency amount in case some costs may pop up unexpectedly. Thus, we can present a clear and complete estimate of the whole project.
