A number of construction industry participants subscribe to the principal that contractors (and subcontractors) who furnish to a construction site non-permanent rental equipment or materials do not have builders' lien rights. In this article I discuss whether, in certain circumstances, contractors who furnish to a job site non-permanent rental equipment or material, enjoy lien rights pursuant to the British Columbia Builders Lien Act (the "Act").

Throughout this article I will use as an illustrative example a typical fence-rental contractor ("Acme Corporation"). I have assumed the following about Acme Corporation, all of which assumptions may be equally applicable to contractors supplying to construction sites the many other categories of non-permanent rental equipment and materials:

1. At some early point in time of a construction project, the contractor's crews mobilize to site the fence panels as well as the bolt-up equipment;

2. the crews erect and bolt together its fence system; and 3. at the end of the project, the crews return to disassemble and de-mobilize the

entirety of its fence system.

Who has lien rights under the Act?

Section 21 of the Act sets out that a contractor or subcontractor2 who, in relation to an improvement, performs or provides work, supplies material, or a combination of the two, has a lien on account of unpaid amounts.

The words "improvement", "work", and "material" require further analysis as they form an integral part of Section 2 and each has a significant impact on my analysis.

1. Improvement

The Act defines improvement to include "anything made, constructed, erected, built, altered, repaired or added to, in, on or under land, and attached to it or intended to become a part of it, and also includes any clearing, excavating, digging, drilling, tunnelling, filling, grading or ditching of, in, on or under land".

Because Acme Corporation cannot convincingly argue that its fencing was ever "intended to become a part of [the project land]", it would need to maintain that its fencing is "attached to [the project land]".

The Act does not require that materials delivered to a construction site be attached to the project land for a certain period of time or into perpetuity. The Act should be read in its grammatical and ordinary sense, which suggests only that the materials must have been, at some point in time, attached to the land.

While individual fencing panels may not be "attached" to the land via bolts or other fastening mechanisms, the fencing system as a whole can be said to be "attached" to the land under its own weight.

The British Columbia Court of Appeal decision Deal S.r.1. v. Cherubini Metalworks Ltd., 2001 BCCA 49, bears out such an argument. In Deal S.r.1., the court considered the definition of "improvement" and concluded that concrete moulds used to form concrete guideway segments for a rapid transit project became an improvement in their own right. The moulds were "erected" or "built" on the land and attached to the land either by bolted connection to the floor or piles or by their own weight. The court further held that although the moulds would likely be removed at the end of the project, they were sufficiently permanent to fall within the definition of "improvement" because they were intended to be in place at least for the duration of the project.

2. Work

Assuming the non-permanent fencing is caught by the definition of "improvement", it is a condition precedent for its lien rights to spring into existence that Acme Corporation establish that it performed or provided work or supplied materials, or both, in relation to the improvement.

The Act defines work to mean "work, labour or services, skilled or unskilled, on an improvement". Acme Corporation's labour forces mobilized, assembled, disassembled, and de-mobilized its fencing system. A strong argument may be made that such actions fall squarely within the definition for "work" because "labour or services, [whether] skilled or unskilled" was performed on the improvement, which is arguably the fence system in its own right (see Deal S.r.1 above).

3. Material

Acme Corporation may further strengthen its position by advancing an argument that it also provided "material" to the project.

The Act defines material to mean "movable property that is delivered to the land on which the improvement is located and is intended to become part of the improvement, either directly or in a transformed state, or is consumed or used in the making of the improvement, including equipment rented without an operator".

Acme Corporation can certainly establish it "delivered" to the project site "movable property". Next, it must also establish its fence system was "consumed or used in the making of the improvement". While the fence system can be said to experience regular wear-and-tear as well as depreciation while the project was being constructed, the stronger

argument would be to show its fencing was "used in the making of the improvement". Without the security and safety benefits of a properly-constructed fencing system, the construction of the project would not be possible. In other words, perimeter fencing is a necessary part of a construction project.

This is bourne out by WorkSafeBC ("WCB") Safety Regulations (see for example WCB Regulations 4.32, 4.33, and 4.34) as well as reasonable industry safety standards and practices.

Acme Corporation may also want to argue its fence system is in effect "equipment rented without an operator". In response, one can expect a counterargument that this particular phrase refers to bare heavy construction equipment (i.e., excavators, dozers, backhoes), not fencing or other non-permanent materials. While not much case law exists with respect to this particular phrase, registering a claim of lien against the title to the project lands would not be easily dismissible as vexatious or frivolous conduct or an abuse of process. All parties would be better served to settle their respective claims and/or secure the claim of lien, rather than expend large sums of money on legal fees to argue an unsettled point of law.


A fundamental principle of the Act is that a company that contributes to a construction project, whether by its provision of labour or materials, or both, enjoys extraordinary statutory lien rights and remedies.

It would be an absurd outcome if a contractor that supplies non-permanent material (and labour setting up such non-permanent material) to a construction site does not enjoy lien rights while a heavy equipment contractor that furnishes an excavator without an operator does. Their respective "materials" equally endured wear-and-tear and undoubtedly lost fair market value. Both contractors contributed to the construction project, whether or not their respective contributions were permanently incorporated into the project.

Companies that supply non-permanent material to a construction project should not be discouraged with respect to their lien rights. Strong arguments may be made and such companies are well-advised to seek out timely legal advice in order to secure their potential builders' lien rights and remedies under the Act.
