The number on the bid is not the number on the final invoice. Every property owner who has been through a construction project knows this — or learns it, expensively, the first time. The change orders start arriving shortly after construction does. Some are legitimate: genuine unforeseen conditions that no amount of pre-construction investigation could have identified. Some are not: scope items that a more thorough bid process would have captured, field conditions that an experienced contractor would have anticipated, coordination failures that generate rework that gets billed as new work.

By the time the project is complete, the gap between the bid and the final invoice is the defining financial memory of the construction experience. It is the number that determines whether the owner calls that contractor again, whether they refer them to colleagues, and whether they describe the experience as one they would repeat or one they would warn others about.

Fixed-price contracting — a bid that is the price, with no subject-to-change clauses, no open-ended allowances, and no change order mechanism for conditions that a competent contractor should have anticipated — is the answer to that problem. It is also, in the current Los Angeles construction market, genuinely rare. Not because contractors don't understand the concept, but because fixed-price contracting is operationally demanding in ways that most firms are not equipped to sustain.

SKS Construction has offered fixed-price bids on every project we have delivered since Sol Shaolian founded the company in 1987. This post explains why fixed pricing is rare in construction, what it actually requires to sustain it, and why we do it anyway.

Why Construction Pricing Is Structurally Resistant to Fixed Costs

To understand why fixed pricing is rare, it helps to understand why construction costs are genuinely difficult to fix — and why the difficulty is not just contractor excuse-making.

Construction projects are site-specific. Unlike manufacturing, where a product is produced in a controlled environment from standardized inputs, construction happens on a unique site with unique soil conditions, unique existing structural conditions, unique access constraints, and unique interactions with regulatory processes that don't always behave predictably. Every project has a discovery component — the field conditions that are revealed when walls are opened, when foundations are exposed, when existing systems are accessed for the first time.

Construction projects are time-extended. A project that takes six months from contract to completion is exposed to six months of material price movement, six months of labor market fluctuation, and six months of supply chain variability. A steel price spike in month three is a real cost increase that the contractor did not control and did not anticipate when the bid was submitted in month one.

Construction projects involve multiple parties. The general contractor depends on subcontractors, suppliers, city agencies, and utility companies — each operating on their own timeline, their own pricing, and their own capacity constraints. A subcontractor who prices a scope in January and is not deployed until April is pricing in a labor market that may have changed materially in the interim.

These are the real conditions that make construction pricing volatile — and that contractors cite, legitimately, when they explain why their bids are not fixed. The conditions are real. The question is who bears the risk they create: the contractor, through fixed pricing that absorbs volatility as a cost of doing business, or the owner, through subject-to-change clauses that pass every variance directly to the client.

The industry default is clear. Almost universally, the risk lands on the owner.

What "Subject to Change" Actually Means in Practice

The language varies across contracts — "subject to change based on field conditions," "preliminary estimate subject to revision," "allowances subject to actual cost," "escalation clause for materials" — but the economic function is the same in every version: the bid price is a projection, not a commitment, and the final price is determined by what the project actually costs rather than what the contractor proposed.

In a market where contractors are competing on bid price to win projects, subject-to-change language creates a specific incentive structure: bid low to win, recover margin through change orders during construction. This is not a cynical characterization of contractor behavior — it is the rational response to a procurement environment where the lowest bid wins and the change order mechanism allows recovery of the margin that the competitive bid didn't include.

The owner who selects the lowest bid on a subject-to-change contract is not selecting the contractor who will deliver the project at the lowest cost. They are selecting the contractor who made the most optimistic projection of what the project would cost — or the contractor who most aggressively used subject-to-change language to make a bid appear competitive while preserving the ability to recover full margin through the change order process.

The practical consequence is that the project selection decision — the moment when the owner commits to a contractor and a price — is made on the basis of information that doesn't accurately represent the actual cost of the project. The accurate cost information arrives over the course of construction, in the form of change order requests that the owner is now obligated to evaluate from a position of limited leverage. The contractor is on site. The project is underway. Switching contractors at mid-project is expensive and disruptive. The owner pays the change order.

This dynamic is so well established in the construction industry that it has its own vocabulary. Experienced owners call it "buy-in" — the contractor buys into the project with a low bid and recovers profit through change orders. It is not illegal. It is not even uncommon. It is the predictable output of a procurement system that selects on bid price without fixed-price accountability.

What Fixed Pricing Actually Requires — The Operational Infrastructure

Fixed-price contracting is not a policy decision. It is an operational capability — and building that capability requires specific investments that most construction firms have not made.

Comprehensive pre-construction investigation

The primary source of legitimate change orders on construction projects is field conditions that differ from the conditions assumed at bid time. A fixed-price contractor must invest in pre-construction investigation sufficient to minimize the probability of those surprises — which means structural assessment before foundation work, geotechnical investigation before grading or shoring, existing condition documentation before demolition, and utility coordination before any work that depends on utility capacity.

This pre-construction investment is a real cost that the fixed-price contractor bears before the project starts and before the contract is signed. It is also the investment that produces the accurate scope definition that fixed pricing requires. A contractor who bids without adequate pre-construction investigation cannot fix the price — because the price depends on conditions that haven't been adequately characterized.

SKS's pre-construction process — led by our in-house licensed structural engineer — includes site assessment, structural condition review, and coordination with LADBS and LADWP before any fixed-price proposal is submitted. We spend real time on every project understanding what we're building before we price it. That is not charity. It is the prerequisite for fixed pricing.

In-house engineering

The gap between what the drawings show and what the field contains is the primary source of change order claims on projects where design and construction are separate. The engineer designs from plans. The contractor builds from the field. When they disagree — and they frequently do — the resolution is a change order.

When the engineer and the contractor are the same organization — when the licensed structural engineer who designed the project is part of the team building it — the gap between drawing and field is managed internally. Field conditions that differ from the design assumption produce an immediate engineering response, not a change order request. The scope adjustment happens within the team, at cost, rather than being billed as additional work.

In-house engineering is the most significant operational infrastructure that enables fixed-price contracting. It is also the investment that most construction firms have not made — because maintaining a licensed structural engineer on staff is a fixed cost that is difficult to absorb without the project volume to support it. SKS has that volume. The engineering is in-house. The fixed pricing is sustainable.

Direct material supply relationships

Material cost volatility — particularly in the current tariff and supply chain environment — is the most frequently cited justification for subject-to-change material pricing. The contractor quotes lumber at current market pricing, lumber prices increase 20% between bid and procurement, and the owner receives a change order for the difference.

A contractor with direct supply relationships — with steel fabricators, lumber suppliers, and electrical equipment distributors who provide pricing that can be locked at bid time — can absorb material cost volatility as a business risk rather than passing it to the client. SKS maintains direct supply relationships built over 39 years of project volume. When we fix a material price in a bid, we have the supply relationship to honor it — not a spot market exposure that gets passed through as a change order.

In-house labor force

Labor cost volatility — wage escalation, subcontractor pricing increases, crew availability constraints — is the other primary source of subject-to-change claims in the current market. A contractor whose labor force is entirely subcontracted is exposed to the subcontractor market at every project: the price at bid time reflects the subcontractor's pricing at bid time, and any increase between bid and mobilization is a change order candidate.

SKS's in-house crews provide labor cost predictability that subcontractor-dependent firms cannot match. We know what our labor costs — because our labor force is our labor force, not a market we access through subcontract bids. That predictability is a direct enabler of fixed-price commitments.

The Change Order Conversation — And Why We Don't Have It

The change order conversation is the most adversarial moment in a typical construction project. The contractor presents a scope addition and a price. The owner disputes the necessity, the pricing, or both. The relationship that began with aligned interests — contractor and owner both wanting the project to succeed — becomes a negotiation where the contractor's profitability and the owner's budget are directly opposed.

This conversation damages the relationship regardless of outcome. The owner who wins a change order dispute — who successfully challenges the contractor's scope justification or pricing — has won a battle that leaves them with less confidence in the contractor's integrity than they had before the dispute. The owner who loses — who pays the change order under construction-phase leverage — has paid a price that was not in the plan and may not be in the budget.

SKS doesn't have this conversation with clients. Not because we never encounter field conditions that differ from the bid assumptions — we do, on every project of any complexity. We have this conversation internally, between our engineer and our project management team, and we resolve it as an operational matter rather than a client billing matter.

The fixed-price commitment means that our problem-solving happens inside the company, not in the client relationship. The client's budget is not the variable that adjusts when the field is difficult. Our operational efficiency is the variable — and 39 years of project volume has made that efficiency sufficient to absorb the variance that subject-to-change contractors pass to their clients as change orders.

What Fixed Pricing Does to the Project Selection Decision

When bids are fixed — when the number submitted is the number that will appear on the final invoice — the bid comparison changes fundamentally.

A subject-to-change bid comparison is a comparison of projections — each contractor's best guess at what the project will cost, with varying assumptions, varying scope definitions, and varying change order philosophies that will determine how far the final invoice diverges from the bid. The lowest projection wins the bid, and the final cost is determined by the construction process, not by the selection decision.

A fixed-price bid comparison is a comparison of commitments. Each contractor is committing to deliver the defined scope at the submitted price. The comparison is real: the lowest fixed price is actually the lowest price, not the most optimistic projection. The highest fixed price may reflect a more thorough scope definition, higher quality materials, or a more conservative contingency — information that is useful in the selection decision.

Fixed-price bidding produces a procurement environment where the selection decision and the cost decision are the same decision — where choosing a contractor is choosing a price, not choosing an opening position in a cost negotiation that will last the duration of the project.

For property owners who have experienced the divergence between bid and final invoice on previous projects, this distinction is not abstract. It is the difference between a project that fits in a budget and a project that requires supplemental financing, delayed other improvements, or created financial strain that the owner was not prepared for when they signed the contract.

Why We Do It Anyway

The question at the center of this post is not just why fixed pricing is rare — it is why SKS does it when the industry default is so clearly moving in the other direction.

The answer is not altruistic. It is strategic.

Fixed-price contracting is the operational discipline that produces the 80% repeat client rate that sustains SKS's business. Clients who receive a final invoice that matches the bid — clients who do not experience the change order negotiation, the budget overrun, or the leverage-dependent payment dispute — return. They refer colleagues. They send the property management company they work with. They call back when the next project arises, without the evaluation process that precedes a first engagement, because the reference point established by the fixed-price experience is one they trust.

The economics of a fixed-price, high-repeat-client business are more favorable than the economics of a subject-to-change, high-client-acquisition business — not in the margin on any individual project, but in the aggregate cost of maintaining a client relationship versus acquiring a new one. Repeat clients don't require marketing spend. They don't require a sales process. They call and ask when we can start.

We do fixed pricing because it is the right thing to do for clients — and because it is the right business model for a firm that intends to be in this market for another 39 years.

Sol Shaolian built it this way in 1987. Shahab and Sam Shaolian run it this way today. The principle is not complicated: tell the client what it costs, charge what you told them, and do not introduce a mechanism that allows the number to change after they've committed to it.

That is fixed pricing. That is why it matters. And that is why, in an industry where it is almost universally abandoned in favor of the more profitable subject-to-change alternative, SKS does it anyway.
