Online Building & Construction Estimators
A precise, comprehensive construction estimate is the foundation of any successful construction project.

Thanks to the combination of industry know-how, cutting-edge technology, and rigorous measurement standards, we deliver estimates that detail the projected costs for every aspect of your project.

What is Construction Estimator Service?
In essence, a building estimate determines the expected costs for completing a building project. This includes estimating expenses for materials, labour, equipment, site preparation, permits, fees, contingencies, as well as contractor profit margins. We combine rates for each of these elements along with accurate measurements of the building design to calculate total projected costs.
To provide accurate and relevant construction estimates, we rely on specialised software, as well as our vast experience and skills in the industry.

But not only that, we also maintain current databases of local labour and material costs while adhering to the rigorous industry standards. Furthermore, our sophisticated takeoff software enables us to extract precise measurements directly from 2D plans.

The Importance of a Detailed Building Estimate
Investing in a detailed and accurate estimate holds immense value throughout every stage of a construction project. Here are the key benefits that a professional estimate provides:
- Reasonable Design Choices. During early design phases, our estimates help architects and clients evaluate different alternatives and make cost-effective changes. This forward-thinking approach prevents unexpected challenges later in the project.
- Realistic Budgeting. Comprehensive estimates offer an accurate portrayal of total project costs. This ensures appropriate financing as well as allows for avoiding unexpected financial challenges that could be detrimental to the project’s success.
- Managed Risks. Contingencies allocated in the estimate act as a safety net. They safeguard against unforeseen events such as material shortages or weather-related delays, minimising their impact on the project.
- Effective Change Management. All-inclusive cost predictions make it possible to determine the price for any modifications occurring during construction. As a result, you are able to push your project forward while maintaining budget control.
- Bidding for Best Value. Precise tendering documents enable contractors to submit competitive bids. Clients, in turn, are able to choose the best value bidder for the project.
- On-Time Delivery. Phased estimates aligned with construction schedules help projects stay on track and on budget.

What is Included in a Building Estimate?
A quality construction estimate includes a full breakdown of all elements that contribute to the total project cost. Line items typically include:
- Building Materials. This list includes all construction materials needed throughout the project lifecycle, from foundation components like concrete to finishing elements such as tiles, flooring and paint. We extract measurements directly from architectural designs and calculate costs using our extensive supplier price database.
- Labour. Building estimates feature man-hours for each specialised subcontractor. This may include carpentry, plumbing, electrical work, and so on. We obtain the rates from regional wage standards.
- Equipment Costs. This section covers the expenses for machinery rentals required throughout construction (such as excavators, lifting equipment, transport vehicles, etc.) as well as specialised tools.
- Construction Site Preparation. All costs linked to preparing the construction area belong to this category. The scopes of work may vary from vegetation removal and ground levelling to utility connections and temporary structures.
- Regulatory Expenses. We can calculate all fees associated with obtaining building approvals, official inspections, and compliance documentation.
- Profit. These represent the contractor’s margins that fund operational overhead and ensure appropriate profit levels.
How Long Does It Take to Produce a Building Estimate?
It takes 3-5 working days to complete construction estimates for standard single-family home projects. More expansive or intricate developments may require 8-12 working days in total to produce. For urgent needs, we offer expedited estimate delivery within 3 days at an extra cost depending on current workload.
The specific timeframe depends on factors like project size, building type, and level of detail required.
How Does it Work?
The process begins when you, as a client, submit your project drawings, specifications, and other essential details. They will provide the information needed to identify required materials, quantities, and labour.
You can expect a quote within one business day. Should you choose to proceed, our qualified estimators will identify exact quantities from your drawings. A combined 40 years of experience paired with advanced measurement software guarantees precise calculations. Next, we price all necessary materials and labour using local pricing obtained from our regularly updated databases. The outcome is a comprehensive estimate, which details scope descriptions, key assumptions, specific exclusions, rates, and relevant terms.
Our construction estimators not only help you to make reasonable decisions about your project’s budget but also serves as a guide for planning. As your project progresses, we can provide updated estimates, ensuring that you have full visibility into any cost fluctuations. We take pride in our efficient and reliable service that gives the support you need to successfully complete your project.
