Jaroslaw Kostrzewa was injured when the scaffolding on which he was working fell.2 Kostrzewa, who was employed by Superior Abatement, Inc. (Superior), brought this *378suit against Suffolk Construction Company, Inc. (Suffolk), alleging negligent supervision.8 Suffolk was the general contractor on the project; Superior was a sub-subcontractor. Summary judgment was granted in favor of Suffolk on the ground that, as a matter of law, Suffolk had not exercised sufficient control over Superior’s work to owe a duty to Kostrzewa. For the reasons set out below, we reverse.

Background. Suffolk was the general contractor for a project (project) to renovate the Saltonstall Building (building) at 100 Cambridge Street in Boston. Suffolk, in turn, subcontracted with North American Site Developers, Inc. (NASDI), to perform demolition and abatement work on the project, including asbestos abatement. NASDI further subcontracted with Superior to perform the asbestos abatement work on the project. Kostrzewa was employed by Superior as an asbestos worker.

Asbestos abatement took place only in contained areas to which access was restricted to licensed asbestos removal or air quality monitoring workers. On May 31, 2002, Kostrzewa and a coworker, Zdzislaw Zylinski (who was also employed by Superior), were removing asbestos within a containment area. The men were working on scaffolding that was approximately twenty feet high and mounted on wheels.3 4 Suffolk did not own and had not erected the scaffolding. When the men wanted to move the scaffolding to work on a new spot, they would either have someone on the ground push it or, using the wall or ceiling, they would themselves pull or push the scaffolding to the new location. In either case, so as to save time, they did not dismount from the scaffolding. At the time of the accident, Kostrzewa was trying to move the scaffolding on which he and Zylinski were standing.

Additional facts from the summary judgment record are set forth in the sections of our discussion to which they pertain.

Discussion. 1. Duty. A general contractor has a duty to its subcontractors’ employees if it “retains the right to control the work in any of its aspects, including the right to initiate and *379maintain safety measures and programs.”5 *Corsetti v. Stone Co., 396 Mass. 1, 10 (1985). See Dilaveris v. W.T. Rich Co., 424 Mass. 9,11-12 (1996). “One who entrusts work to an independent contractor, but who retains the control of any part of the work, is subject to liability for physical harm to others for whose safety the employer owes a duty to exercise reasonable care, which is caused by his failure to exercise his control with reasonable care.” Restatement (Second) of Torts § 414 (1965). Whether a general contractor has sufficient control to be liable to a subcontractor’s employee is a question of fact for the jury. Corsetti v. Stone Co., supra at 11. It should not be determined on summary judgment unless, viewing the evidence in the light most favorable to the plaintiff, the undisputed material facts demonstrate, as matter of law, that the defendant did not exercise any “meaningful control, however minimal, over the subcontractor.”6 Dilaveris v. W.T. Rich Co., supra at 11.

Viewed in the light most favorable to Kostrzewa, the summary judgment record showed the following:7

The contract between Suffolk and the building owner conferred on Suffolk general responsibility and control for the project, including responsibility for safety. See Corsetti v. Stone Co., 396 Mass, at 11 n.8 (while a contract cannot vary or heighten any duty a contracting party may owe to a noncontracting party, it can be evidence of control). The contract provided that “[Suffolk] shall be solely responsible for and have control over construction means, methods, techniques, sequences and *380procedures and for coordinating all portions of the Work under the [c]ontract . . . .’’In the area of safety, Suffolk was “responsible for initiating, maintaining and supervising all safety precautions and programs in connection with the performance of the [c]ontract.” Moreover, Suffolk was required to “take reasonable precautions for safety of and shall provide reasonable protection to prevent damage, injury or loss to . . . employees on the Work and other persons who may be affected thereby.” Suffolk was required to “erect and maintain . . . reasonable safeguards for safety and protection.” The contract also allocated to Suffolk sole responsibility “for all injuries to persons . . . caused by or resulting from [its] negligence.” Finally, the contract required Suffolk to “designate a responsible member of [its] organization at the site whose duty shall be the prevention of accidents.” These various provisions of the contract indicate that Suffolk was to control the project, including all aspects of safety.8

In addition to the contract provisions, there was further evidence suggesting that Suffolk had more than minimal control over the safety aspects of the project. Suffolk had a project safety manager on site. Suffolk’s safety manual required its management to “maintain an interest and participate in the safety program by checking on safety when visiting a Job site,” placed responsibility on Suffolk’s director of safety to perform periodic safety inspections of the project site, and required Suffolk’s superintendent to conduct routine safety inspections and to address any safety issues.

With respect to the asbestos abatement work in particular, Suffolk, as required by the contract documents, created viewing windows so that supervisors could observe the work taking place in the containment areas, which were otherwise surrounded by an opaque barrier. It was not unusual for Suffolk employees to look through the windows. On the day of the accident, the *381project’s daily log (which was on a Suffolk form) showed that a Suffolk foreman performed “Supervision, Safety, [and] Security” on the project. The log shows only asbestos abatement work occurring on that day, allowing the inference that the Suffolk foreman was performing supervision, safety, and security in connection with the asbestos abatement work.9 Furthermore, Suffolk required Superior to report weekly on its (Superior’s) safety meetings. The report was submitted on Suffolk letterhead.

To be sure, Suffolk submitted evidence suggesting that it had little, if any, access to the containment areas or supervision over the asbestos removal work within those areas.10 This, however, was not sufficient to satisfy Suffolk’s burden on summary judgment. If Suffolk gave “directions for the work, fumishe[d] equipment for it, or retain[ed] control over any part of it,” it had a duty to those working on the project. Corsetti v. Stone Co., 396 Mass, at 9-10, quoting from Prosser, Torts § 71, at 469 (4th ed. 1971). Moreover, in assessing a motion for summary judgment our role is not to assess whether competing evidence favors the defendant; rather, summary judgment must be denied unless, viewing the evidence in the light most favorable to the plaintiff, the defendant is entitled to judgment as a matter of law. See Augat, Inc. v. Liberty Mut. Ins. Co., 410 Mass. 117, 120 (1991), citing Mass.R.Civ.P. 56(c), 365 Mass. 824 (1974).

Finally, Suffolk argues that, even if it owed a duty to Kostrzewa, that obligation was contractually delegated to NASDI and Superior. We disagree. Suffolk’s subcontract with NASDI required NASDI to assume responsibility for the safety of its own (NASDI’s) employees.11 It did not impose an obligation on NASDI with respect to Superior’s employees. Although the *382subcontract required NASDI to insert “this clause in each of its sub-contracts and enforce the same,” no such provision is included in the letter agreement between NASDI and Superior. Thus, there is no contractual provision delegating sole responsibility for the safety of Superior’s employees (such as Kostrzewa) to either NASDI or Superior.

2. Breach. We turn briefly to whether, as matter of law, Suffolk did not commit a breach of its duty towards Kostrzewa.12 There was evidence that the asbestos workers regularly moved the scaffolding without dismounting. This, combined with the testimony that it was not unusual for Suffolk employees to be looking through the viewing windows into the containment areas, permitted an inference that Suffolk either knew or should have known that scaffolding was not being used safely and that Suffolk, as a result, was negligent in supervising the safety of the worksite. See 454 Code Mass. Regs. § 10.104(6)(f)-(h) (1993) (scaffolding shall only be moved with force applied as close to the base as possible, with no one on the scaffolding, and shall have its wheels locked when in place).

For the reasons set out above, we reverse the judgment.

So ordered.
