What Is Construction Cost Estimating? Westgate Guide to Smarter Building

Westgate Koenig

Are you looking for a partner to efficiently guide you through the complexities of a capital project? Would you like to drive collaboration and establish strong working partnerships across the entire project team? Are you seeking accurate, unbiased cost clarity and improved risk mitigation?

Building Smarter: What Construction Cost Estimating Really Means

In custom construction, confidence doesn’t come from guesswork—it comes from clarity. That’s exactly what construction cost estimating is designed to deliver. Whether you're building a new residence, expanding a portfolio, or revitalizing an older structure, a comprehensive estimate ensures you know what to expect before a shovel hits the ground.

At Westgate, cost estimating is more than pricing materials and labor. It's a foundational tool that protects your investment and strengthens decision-making from day one.

What Is Construction Cost Estimating?

Construction cost estimating is the process of forecasting the total cost of a construction project—accounting for materials, labor, equipment, subcontractors, overhead, and contingencies.

It’s part budget map, part reality check. And it’s critical whether you’re still finalizing designs, bidding out scopes, or weighing return on investment.

Why It Matters

Cost overruns are one of the biggest risks in construction—and they rarely come from a single big error. They build up through misaligned assumptions, hidden scope creep, and insufficient early planning.

A thorough estimate:

  • Sets realistic expectations
  • Identifies cost drivers early
  • Flags risks before they become budget problems
  • Keeps teams accountable throughout the project

Without it, decisions are reactive. With it, decisions are strategic.

What’s Included in a Good Estimate?

A high-quality construction estimate typically includes:

  • Detailed quantity takeoffs from plans
  • Unit pricing for labor, materials, and equipment
  • Allowances and contingencies for unknowns
  • General conditions and overhead
  • Escalation factors for long timelines or inflation-sensitive materials
  • Optional scope breakouts for value engineering or alternates

At Westgate, we tailor estimates to the scope and purpose—whether you’re looking for a big-picture range or a line-by-line cost projection with hard bids.

Types of Construction Cost Estimates

Estimates evolve as the project progresses. Here’s how they typically break down:

1. Conceptual Estimates

Rough budgets built on early-stage designs or square footage benchmarks—used for feasibility studies and financial planning.

2. Preliminary/Schematic Estimates

Refined as designs develop, often used to guide early decisions and align scope with budget before documentation is finalized.

3. Detailed Estimates (Design Development / Construction Documents)

Line-item breakdowns used for budgeting, lender approvals, and contractor bidding. These carry the most weight in locking in financial expectations.

Who Uses Cost Estimates—and When?

Construction cost estimating supports many key moments:

  • Owners and developers use it to decide if a project is viable
  • Architects and designers use it to align their vision with the budget
  • Contractors and subs use it to price their work and build schedules
  • Lenders and partners use it to evaluate risk and release funds

The earlier and more frequently it’s used, the fewer surprises downstream.

Our Estimating Approach at Westgate

We’re not here to win low-bid competitions. We’re here to build right the first time. That starts with estimates rooted in real market conditions, deep construction experience, and a relentless focus on owner priorities.

We work closely with architects, engineers, and builders to clarify scope, prevent budget bloat, and adjust proactively as designs evolve. You get transparency early—so you can make smarter decisions later.

Know What It Takes—Before You Build

Building without a solid cost estimate is like navigating without a map. At Westgate, we give owners and investors the clarity they need to move forward confidently—with eyes wide open.

Let’s put real numbers behind your vision—and build with certainty.
