Many construction surprises can be identified before project management moves into construction. A simple pre-construction review by commercial construction contractors gives owners a clearer picture of the site’s conditions, code requirements, project scope, and realistic costs before major money is committed.
None of this is a secret in the industry. So why does the pre-construction review still get skipped?
It’s not carelessness, it’s momentum. A lease deadline is getting closer. Financing has been approved. Everyone wants to start building. At that point, stopping for another review can feel like an unnecessary delay.
But a $500 pre-construction review is insurance for the money you’ve already invested. It helps catch problems before they become expensive change orders, redesigns, or construction delays. Spending a few hundred dollars now can help protect thousands, or even tens of thousands, later.
Why a Few Hundred Dollars Can Prevent Six-Figure Mistakes
Construction economists have been tracking this exact pattern for years. Rework and change orders driven by things that weren’t caught early cost the U.S. construction industry roughly $177 billion a year. On individual projects, change orders typically eat up 10 to 15 percent of total contract value on major projects, with some distressed projects seeing that climb past 25 percent. That’s not a rounding error. On a $2 million commercial build, 15 percent is $300,000. That’s money that was never in the original plan and now has to come from somewhere.
10–15% Typical share of total contract value consumed by change orders on major projects | 85% Of construction projects experience some form of cost overrun | 56.5% Of cost overruns trace back to design changes made after work began |
What makes a change order so expensive is everything that gets dragged along with it. A four-hour fix can quietly turn into ten hours once it’s tracked, because the crew has to stop, re-sequence, wait on a decision, and then restart. And if the fix pushes the schedule out, the project keeps paying for the site trailer, the super’s salary, insurance, and every other standing cost of just having a job open.
What This "$500 Decision" Is
It goes by a few names depending on who’s doing it:
- pre-construction site review
- due diligence walk-through
- plan-and-code check
Basically, it’s before money is committed; someone who builds things walks the site, reads the intended scope against it, and flags what’s going to be a problem before it becomes an expensive one.
It sits a rung below the full feasibility study most owners have heard of. A formal feasibility study typically runs 1 to 5 percent of total project value in Canada, and pre-construction services as a whole are commonly budgeted at 5 to 10 percent of the total project cost once design, engineering, and estimating are all factored in. The $500-ish site review is the entry point below that. It’s the fast, low-cost gut check that tells an owner whether the bigger, more formal study is even worth commissioning.
What’s Included in a Pre-Construction Review
✓ Zoning and occupancy fit. Does the intended use of the building match what the zoning and occupancy classification allow?
✓ Rough code compliance check. A first pass against the applicable building code to catch the obvious conflicts (e.g., egress, accessibility, fire separation, etc.)
✓ Site and structural red flags. Visible signs of soil movement, drainage problems, or structural elements that don’t match the drawings, flagged for a full engineering look if warranted.
✓ Mechanical, electrical, and plumbing capacity. Whether existing services can support the new use.
✓ A realistic, order-of-magnitude budget. A sanity check on whether the project as imagined is anywhere close to what it will cost.

Three Ways Skipping the Review Gets Expensive
1. What the Ground Could Be Hiding
Soil is the classic one. That’s why contractors recommend a geotechnical report, a soil investigation that tells engineers exactly what the foundation will be built on. The report costs:
- $1,000 to $5,000: Standard site
- $10,000 or more: Larger commercial developments or hillside properties.
- Six figures: Highly complex projects can reach well into the six figures.
That may seem expensive, but skipping the report can cost far more. Problems like weak soil, high groundwater, undocumented fill, or unexpected bedrock are some of the most common reasons construction projects fall behind schedule and go over budget.
By then, there’s no inexpensive fix. Heavy equipment is already on site, workers are waiting, and engineers may have to redesign the foundation before construction can continue. What could have been identified during planning can quickly turn into weeks of delays and thousands of dollars in additional costs.
The pattern repeats across engineering firms that specialize in this exact risk: information that’s cheap to gather in week one becomes exponentially more expensive to act on once concrete decisions have already been poured, sometimes literally. – Nanaimo Builders and Renovations
2. What the Code Requires
In British Columbia, the updated 2024 BC Building Code introduced new earthquake design and adaptable dwelling unit requirements. These rules apply to most permit applications submitted on or after March 10, 2025. They are especially important on Vancouver Island, which is one of the province’s higher seismic-risk regions.
It’s also important to know which code applies to your project. Most communities on Vancouver Island, including Nanaimo, follow the provincial BC Building Code. However, the City of Vancouver has its own building bylaw with additional requirements.
That’s why a pre-construction review matters. It confirms which building code and local regulations apply to your project based on where the site is located and when the permit application is submitted.
3. Is Your Budget Based on Reality?
National average commercial construction costs in Canada currently range from $200 to $300 CAD per square foot, but that figure only tells part of the story. The actual cost of a project can vary significantly depending on factors such as:
- Building type
- Complexity of its mechanical and electrical systems
- Quality of finishes.
That’s why relying on a national average alone can be misleading. As several Canadian cost guides point out, applying a broad cost-per-square-foot estimate to a specific site is an oversimplification that can lead to unrealistic budgets.
Compare the Cost of Planning vs. the Cost of Rework
Skipped or Rushed | Caught Early, for Roughly $500–$2,000 |
Foundation redesign mid-excavation after hitting rock or poor soil | Geotechnical red flag noted before design is finalized |
Permit rejected or revisions ordered after full drawing submission | Code and zoning fit confirmed before drawings are commissioned |
HVAC/electrical retrofit after tenant improvement is half-built | Existing service capacity checked before the lease is signed |
Change order negotiated under schedule pressure, markup and all | Scope gaps identified while there’s still room to plan around them |
Carrying costs while the project sits stalled | No stall, because there was nothing left to discover |

Frequently Asked Questions
What is constructability review, and why is it important for project management?
A constructability review evaluates whether a project can be built efficiently using the proposed design. Contractors assess sequencing, site access, material availability, equipment requirements, and potential conflicts between building systems. Identifying constructability issues before construction begins can reduce delays, minimize rework, and improve overall project efficiency.
What are long-lead construction materials, and why should commercial construction contractors know about them?
Long-lead items are materials or equipment that require extended manufacturing or shipping times before they arrive on site. Examples include electrical switchgear, rooftop HVAC units, custom glazing systems, elevators, and specialized structural steel components. Identifying these items during pre-construction allows contractors to order them early and reduce the risk of project delays.
How do utility capacity limitations affect commercial, industrial, or residential construction projects?
Existing electrical, water, sanitary, and gas services may not have enough capacity to support a new commercial operation. Restaurants, medical clinics, manufacturing facilities, and fitness centres require larger utility services than standard office spaces. Identifying these limitations early allows upgrades to be incorporated into the project schedule rather than becoming unexpected delays during construction.
