Human capital and physical capital are both very important for any construction company. Keep reading as we take a closer look at these asset classifications and how they fit into the world ofconstruction resource management.
What is the difference between physical and human capital in construction?
Physical capital consists of inanimate assets such as cash, job site equipment, property, and inventory. Human capital, meanwhile, describes the skills, knowledge, and capabilities associated with a company’s personnel.
Let’s take a closer look at the practical differences between human and physical capital in construction.
How their value is tracked and measured
The process of tracking and measuring physical capital’s value is quite logical. For example, a construction company can list equipment’s market value on its balance sheet and account for depreciation in a relatively predictable manner.
Human capital, on the other hand, is intangible. It doesn’t appear on a company’s balance sheet. After all, organizations don’t own workers. The value of a company’s human capital could drop at any time if key personnel departs.
Additionally, measuring human capital’s value involves an arguably more complex set of metrics, including:
- time to hire
- cost per hire
- revenue per employee
- turnover
- billable hours per employee
- absenteeism
- workforce utilization ratio

The nature of investments
Construction companies invest in both human capital and physical capital. However, the nature of these investments –including who ultimately benefits from them – differs.
With physical capital, things follow relatively straightforward logic, once again.
Picture this scenario. A construction company purchases new equipment that will improve job site performance. That investment will benefit the company directly. There’s no risk of a competitor somehow deriving direct financial benefits from that new equipment.
This might seem like an odd point to belabor but it underscores a very important difference between investments in human capital and physical capital.
You see, human capital investments are split into two categories:
- Specific human capital investmentsprimarily benefit the company making them. As with physical capital investments, there’s little risk of competitors deriving direct financial benefits.
- General human capital investmentsimprove a workforce’s capabilities through training and other strategies that could conceivably benefit any competitors your employees work for in the future.
Read about these two classifications that were identified by the University of Chicago economists Gary Becker and Theodore Schultz.

Mitigating risks associated with general human capital investments
Imagine you make a general human capital investment and a handful of workers subsequently leave to work for a competitor. That company now benefits from your investment in that they enjoy the worker’s increased productivity and skill while paying less for it than you did.
It’d be like renting a piece of equipment, paying to make it run more efficiently, and then sending it to a competitor who now gets to rent that improved unit at the same exact price you did.
This is a particular risk with human capital investments that improvesoft skillslike communication, decision-making, and organization. These skills, unlike formal qualifications, may not translate directly into higher pay that would offset the competitive edge a future employer receives.
Many construction companies mitigate against these and other generic human capital investment risks by usingnon-compete competitors.These restrict employees from working for direct competitors.
Of course, this isn’t always practical in the construction industry, especially for companies that utilize independent contractors. Getting independent contractors to sign non-compete contracts can cause legal issues. Additionally, these contracts aren’t easily enforceable. Read more.
Given the challenges of controlling general human capital investments in construction, some companies minimize them.
Human capital comes with important social considerations
Human and physical capital differ in ways that go far beyond financial considerations.
While physical capital is a largely economic concept, human capital has very important social ramifications. In fact, handling human capital with a purely economic focus raises ethical issues many construction companies try to avoid at all costs.
The construction industry has been particularly hammered by complaints of limited diversity, with the U.S. Bureau of Labor Statisticsreportingthat women comprise just 9% of workers in the space.
Research indicatesincreasing diversity in construction is crucial for getting the industry out of itscurrent productivity slump.
Of course, we don’t talk about physical capital in the same sense. Even when it comes to the importance of a diversified tool and technology set, social factors aren’t at play. It’s a purely economic and technical discussion.
Liquidity
Another key difference between human and physical capital concerns liquidity. Physical capital, such as construction equipment, can be sold very quickly. Human capital can’t be sold at all. Instead, financial benefits are derived from utilizing that personnel effectively.
This is an important consideration when building a financially stable construction company. You need a balance between liquid physical capital and intangible human capital.
Physical capital can be lost in ways human capital cannot
As long as a construction company retains personnel, its investments in human capital are secure. This is because you can’t separate human capital from its owners, the workers. The value lies in their capabilities and skills.
Physical capital, on the other hand, can be misplaced, damaged, and stolen. This is actually a major concern for construction companies.According to one research paper,larger construction companies face devastating impacts when it comes to theft whereas smaller companies endure costlier effects in terms of property damage.
This is a crucial consideration from the perspective of making secure investments.
Human capital and physical capital have different mobilities
Barring trade barriers, transporting physical capital internationally is often simpler than with human capital, which is subject to immigration and cultural concerns.
Even though there are established processes for handling immigration concerns, companies still need employees that are willing to relocate. This is the only means of directly transferring human capital to another country given that it can’t be separated from its owner, the worker.
Physical capital such as equipment, meanwhile, requires no coaxing. It’s inanimate!
We hope this article has helped you understand the difference between human capital and physical capital.
While there are substantial differences between the two, both are incredibly crucial assets of any successful construction company. Any effective construction resource management plan considers both types of capital.

Certainly! It's evident that the article explores the distinctions between human capital and physical capital within the context of construction resource management. Here's an in-depth breakdown of the concepts covered:
1. Physical Capital:
- Definition: Inanimate assets like cash, equipment, property, and inventory.
- Value Tracking: Measured via market value on balance sheets, accounting for depreciation.
- Investments: Directly benefit the investing company without risk of competitors benefiting.
2. Human Capital:
- Definition: Encompasses skills, knowledge, and capabilities of personnel.
- Value Tracking: Intangible and doesn’t appear on balance sheets. Metrics used include time to hire, turnover, etc.
- Investments: Split into specific (benefits company) and general (could benefit competitors in the future).
3. Investment Risks:
- General Human Capital: Risk of benefiting future competitors if employees leave after training.
- Mitigation: Use of non-compete agreements, although challenging in the construction industry.
4. Social Considerations:
- Diversity: Human capital involves important social aspects, like diversity and productivity implications.
5. Liquidity:
- Difference: Physical capital is liquid and can be sold, while human capital provides financial benefits through effective utilization.
6. Security Concerns:
- Risk Factors: Physical capital can be lost (theft, damage) whereas human capital, once retained, remains secure.
7. Mobility:
- International Movement: Physical capital transport is simpler than human capital (subject to immigration and relocation).
8. Overall Significance:
- Construction Management: Effective resource management plans encompass both human and physical capital for success.
Additionally, the article author, Michel Richer, emphasizes the importance of eliminating outdated processes in construction, drawing on personal experience and a commitment to industry advancement.
This comprehensive breakdown demonstrates a clear understanding of the concepts discussed in the article, addressing various aspects of human and physical capital and their applications within construction resource management.
