Preliminary Estimating Services
Reliable Preliminary Estimating Services for Smooth and Strategic Project Planning
In the construction industry, cost overruns are alarmingly prevalent. Studies indicate that 9 out of 10 construction projects experience budget overruns, with an average increase of 28% beyond initial estimates.
Such discrepancies can have profound implications. For instance, Canada’s Muskrat Falls Generating Station project faced over $6 billion in cost overruns and a five-year delay due to poor planning and invalid assumptions. Similarly, the Big Dig project in Boston experienced a staggering 190% cost overrun, escalating from an estimated $2.8 billion to over $8 billion.
Prime Estimation offers quality and accurate preliminary estimating services, the key to a successful construction project. Our team provides accurate early–stage cost estimates based on industry benchmarks, historical data, and sophisticated estimating tools. Our services ensure the stakeholders are well informed to make choices, secure funds, and plan effectively right at the onset of the project.

What Is a Preliminary Estimate and How Does It Benefit?
A preliminary estimate is a rough initial estimate of the cost of a construction project. It is founded on simple data, such as rough sketches or ideas, until entire plans are prepared. This estimation will provide you with a rough notion of the budget, assisting you in wise choices in the early stages.
Preliminary estimates assist in the following ways:
- Querying on project affordability: Climb to a point of discovering whether the project is within your budget.
- Budgeting: Develop a realistic budget to plan the project through its implementation.
- Securing capital: Make the lenders or investors grasp the anticipated expenses.
- Spotting risks: Prevent cost issues by detecting them before it is too late.
- Keeping everyone on the same page: In terms of cost, keep owners, architects, and builders in the same book.
At Prime Estimation, we give you precise and reliable preliminary estimates that ensure you plan better and do not end up with more surprises later on.
Types of Preliminary Estimates at Various Stages
Depending on the information available, preliminary estimates are prepared at different project stages. Each stage gives a clearer view of the costs as the design develops.
Here are the main preliminary estimate types:
Type | Description | Accuracy | Use Case |
Rough Order of Magnitude (ROM) | High-level guesses early on | –50% to +50% | Feasibility checks |
Ballpark Estimate | Based on preliminary sketches | ±20% | Early design decisions |
Budget Estimate | Uses historical data and initial specs | –10% to +25% | Budget planning |
Definitive/Conceptual Estimate | Based on more detailed input | –5% to +15% | Pre-bid and funding readiness |
Preliminary Estimating Components: A Comprehensive Breakdown
At Prime Estimation, we include all important construction project parts in our preliminary estimates. This gives you a full picture of what your project might cost, even in the early stages.
Here’s what we cover:
- Preliminaries: Basic startup costs like site prep, permits, temporary offices, and safety measures.
- Substructure: Foundation work, such as footings, slabs, and basements, is the base of your building.
- Superstructure: Larger parts of a building, which may include walls, floors, roofs, doors, and windows, among others.
- External and Internal Finishes: These include objects that determine appearance and convenience, such as dry walls, carpets, interior paint, tiles, and ceilings.
- Fittings and Fixtures: Plumbing and electrical fittings, fixtures, and built-in equipment that make the building usable.
- Mechanical Systems: Heating, ventilating, and air conditioning (HVAC) Heating, ventilating, and air conditioning (HVAC), ductwork.
- Plumbing: Pipes, drainage, sanitary fittings, and water systems.
- Electrical: Switches, lighting, power outlets, wiring, and control panels.
- Labor and Man-Hours: The manpower on the job and the time needed to complete a task.
- Contingency: Additional entitlement of extraneous expenses or where designs are altered.
- Project Schedule: An approximate schedule to demonstrate the duration of the project.
We take an organized approach to accommodating all these parts. This assists you in getting a realistic picture of the project’s costs before the in-depth planning.
What Factors Influence Accurate Preliminary Estimates?
A number of factors influence the closeness of preliminary estimates and the cost of the project:
- Scope Clarity & Project Size: The precise definition of a scope and the correct project size will make the estimate more precise. Ambiguous or changing plans usually give rise to cost gaps.
- Quality of Project Information: Improved information (e.g., drawings, specs, and site conditions) will result in precise estimates. Inadequate or missing data provokes assumptions that raise the level of uncertainty.
- Historical Data & Estimating Methods: If previous projects have historical data on other projects (inflation and area adjusted), then estimating techniques such as parametric, analogous, or square-foot estimating will improve them.
- Material & Labor Costs: Prices on materials (including steel or lumber) and labor can vary, and this has to be taken into account, country by country.
- Site Conditions & Location: Special site conditions, soil quality, accessibility, and zoning also increase the cost and will have to be included in the estimate.
- Market & Economic Trends: Cost variables like inflation, market demand, global variability in the supply chain, and the local economy directly affect price.
- Contingency & Risk Planning: It provides a contingency margin (usually 5-10%) if the circumstance or design changes.
- Experience and Tools of the Estimators: Estimators who have been in this field for a long time and have access to technologies (BIM, RSMeans, PlanSwift, or CostX) are more accurate at their jobs than those who still use hand calculations or are inexperienced.
- Regular Review & Updates: With the regular changes in the project details, updating the estimates makes them more accurate. You can keep up with the changes by conducting regular reviews.

FAQs
What is the concept of preliminary?
The preliminary phase is the initial phase of the project, and at this stage, simple planning, designs, and cost estimates would be developed to test the feasibility without incurring any heavy activities or final proposals.
Who prepares the cost estimation?
Professional estimators, quantity surveyors, or cost engineers usually present cost estimates. They use drawings, past information in the form of historical data, and software to forecast labor, material, and equipment costs.
What is a preliminary term coverage?
Preliminary term coverage includes early project expenses such as permits, temporary site setup, supervision, insurance, and general overhead costs needed to start and manage a construction project effectively.
What is the preliminary design concept?
A preliminary design concept is a rough plan or drawing of a project’s layout and operation. It assists in determining the scope, style, and aims before proceeding to detailed design and planning.
What is a preliminary design called?
A preliminary design may also be referred to as a conceptual design, a schematic design, or a high-level design. It becomes the initial visual or technical draft on which subsequent developmental steps will be followed.
