IN THE COURT OF APPEAL OF THE STATE OF CALIFORNIA

FIRST APPELLATE DISTRICT

DIVISION FIVE

RON BATTON,

Plaintiff and Appellant,

v.

ALTEN CONSTRUCTION, INC.,

Defendant and Respondent.

A135146

(Marin County

Super. Ct. No. CIV1005862)

I. INTRODUCTION

Plaintiff Ron Batton, an employee of a construction subcontractor, alleges he 

sustained injuries while descending an unfinished stairway on a construction jobsite. 

Batton sued the general contractor, defendant Alten Construction, Inc. (Alten), for 

damages, asserting claims for negligence, negligence per se, and breach of contract (on a 

third party beneficiary theory). The trial court entered summary judgment for Alten, 

holding that Privette v. Superior Court (1993) 5 Cal.4th 689 (Privette) and its progeny

barred Batton‟s negligence claims, and that Batton lacked standing to pursue his contract 

claim. Batton appeals. We conclude triable issues of material fact exist as to Batton‟s 

negligence claims, but not as to his contract claim. We affirm in part and reverse in part.

II. FACTUAL AND PROCEDURAL BACKGROUND

A. The Contracts

On October 2, 2008, Alten entered a contract with the City of Sausalito (City) to 

construct a public safety building that would include police and fire stations. The 

contract incorporates a document designated “Section 00700[,] General Conditions.”
2

Among other matters, Section 00700 addresses the relationships among City, 

Alten, and other contractors or utility owners. (¶ 6.2.) Alten must “afford all other 

contractors, utility owners and City . . . proper and safe access to the Site . . . .” (¶ 6.2.A.) 

Alten also must “coordinate its Work with the work of other separate contractors, City 

. . . , and utility owners.” (¶ 6.2.B.) Paragraph 6.2.D. specifies: “[Alten‟s] duties and 

responsibilities under paragraph [sic] of this Section 00700 are for the benefit of City . . . 

and also for the benefit of such other contractors and utility owners working at the Site to 

the extent that there are comparable provisions for the benefit of [Alten] in the direct 

contracts between City . . . and such other contractors and utility owners.”

Other portions of Section 00700 provide for Alten‟s control and supervision over 

the jobsite. Alten must “supervise, inspect, and direct Work competently and efficiently” 

(¶ 8.1.B.), and “shall have sole care, custody, and control of the Site and its Work areas” 

(¶ 8.3). Alten is responsible “for initiating, maintaining and supervising all safety 

precautions and programs in connection with the Work” (¶ 16.2.A.), and must comply 

with applicable safety laws and regulations (¶ 16.2.B.). Alten is “fully responsible for the 

safety of its and its Subcontractors‟ employees, agents and invitees on the Site.” 

(¶ 16.3.B.) Within designated work areas, and with the exception of “routes for ingress 

and egress over which [Alten] has no right of control,” Alten must “provide safe means 

of access to all places at which persons may at any time have occasion to be present.” 

(¶ 16.3.C.)

On October 16, 2008, Alten entered a subcontract with Galletti & Sons, Inc. 

(Galletti). The subcontract required Galletti to provide concrete reinforcement (rebar) for 

the project. Section 22 of the subcontract specifies Galletti is an independent contractor 

and must comply with applicable laws and regulations. Section 18 of the subcontract, 

entitled “Safety Practices,” provides: “Subcontractor shall comply fully with all laws, 

orders, citations, rules, regulations, standards, and statutes with respect to occupational 

health and safety, the handling and storage of hazardous materials, accident prevention, 

safety equipment and practices including the accident prevention and safety program of 

Owner and Contractor. Subcontractor shall conduct inspections to determine that sage 
3

[sic] working conditions and equipment exist and accepts sole responsibility for 

providing a safe place to work for its employees and for employees of its subcontractors 

and suppliers of material and equipment, for adequacy of and required use of all safety 

equipment and for full compliance with the aforesaid laws, orders, citations, rules, 

regulations, standards and statutes.” Galletti‟s subcontract was solely with Alten; Galletti 

had no direct contract with City.

On December 1, 2008, Alten entered a subcontract with Kwan Wo Ironworks, Inc. 

(Kwan Wo). Kwan Wo was to install interior stairways in the project.

During the course of construction, Alten exercised general control over the 

worksite and the project.

B. Batton’s Injury

Batton, an ironworker, was employed by Galletti as a foreman. Batton alleges in 

his complaint that, on August 20, 2009, he “twisted and fell” while descending an 

unfinished stairway on the construction site and sustained injuries. Batton and his 

supervisor, Steve Wheeler, completed reports about Batton‟s injury. The reports state the 

bottom step of the stairway was 18-24 inches off the ground, and Batton fell when 

stepping from the bottom step to the ground. Batton received workers‟ compensation 

benefits through Galletti.

C. Proceedings

1. Alten‟s Motion

After Batton filed suit, Alten moved for summary judgment or summary 

adjudication. Alten contended Batton‟s negligence causes of action failed because Alten 

“owed no duty of care to [Batton] having contractually and impliedly delegated that duty 

to [Batton‟s] employer, [Galletti].” Relying on the Privette line of cases limiting the 

liability of a hirer of an independent contractor for injuries to the contractor‟s employees, 

Alten argued its exercise of “general control over the workplace” was insufficient to 

support liability. As to the breach of contract cause of action, Alten argued Batton lacked 

standing to pursue third party beneficiary recovery.
4

In support of its motion, Alten submitted excerpts of the relevant contracts, as well

as discovery responses showing Batton knew the stairway was under construction and 

was aware he needed to use caution when using it, and Galletti did not advise Batton to 

use caution on or around the stairway. Alten also submitted declarations from Paul 

Fitzgerald, Alten‟s project supervisor, and Trevor Simon, the acting supervisor in 

Fitzgerald‟s absence on the date of Batton‟s injury. Fitzgerald and Simon stated they did 

not control or direct the work of Galletti or Kwan Wo.

2. Batton‟s Evidence in Opposition

In his opposition, Batton argued that, under Hooker v. Department of 

Transportation (2002) 27 Cal.4th 198 (Hooker), the hirer of an independent contractor 

may be liable for injuries sustained by an employee of the contractor if the hirer retains

control over safety conditions at a worksite and exercises that control in a way that 

affirmatively contributes to the employee‟s injuries. Batton argued Alten was liable 

under the negligent exercise of retained control theory outlined in Hooker.

Batton submitted excerpts of deposition testimony by employees of Alten and 

Kwan Wo about the construction of the stairway and other matters. According to this 

testimony, after Kwan Wo installed the steel stairway, the stairway still required concrete 

treads to be poured in the step pans, and a concrete landing to be poured beneath the 

bottom step, which were outside Kwan Wo‟s scope of work and fell within Alten‟s scope 

of work. No handrail had yet been installed. Kwan Wo employee Wen Situ testified 

Kwan Wo used caution tape to close off the top and bottom of the stairway, and Situ told 

Alten the stairs could not be used yet.

Pending completion of the stairway, Alten placed temporary wood blocks in the 

stair pans and a temporary guardrail on the steps. The wood blocks in the stair pans did 

not completely fill the pans; there were gaps on the right-hand side of the steps (facing up 

the stairs). Alten supervisors testified the guardrail and the blocks in the pans were 

routine safety practices for unfinished stairways. Alten took these measures because 

Galletti‟s ironworkers were working off the stairway, using it as “scaffolding” to install 

rebar on the shear wall adjacent to the stairs. Alten supervisor Fitzgerald testified Galletti 
5

was allowed to use the stairway for that purpose, but not as a means to gain access to the 

second floor.

In addition to the wooden step blocks and the handrail, Kwan Wo employee Situ 

testified Alten‟s workers placed wooden planks below the bottom step. Situ testified 

Alten‟s workers removed the caution tape Kwan Wo had placed at the top and bottom of 

the stairway, because Alten‟s workers needed to use the stairs to put the wood blocks in 

the steps. When asked on cross-examination whether he personally saw Alten‟s workers 

“take off the tape and place it on the ground,” Situ responded: “I‟m not sure. I cannot be 

positive.”

Batton submitted a declaration in which he stated his employment required him to 

carry tools and materials and to ascend and descend the unfinished stairway. Batton 

stated the stairway and one other stairway in the same general condition provided the 

only means of access to the second floor where Galletti ironworkers were placing rebar. 

Batton had little experience on this jobsite and had only used the stairway on a few 

occasions. He “could see that with some wood, someone had attempted to make [the 

stairway] available for use by all trades on the job.” Batton stated: “The stairway where 

I received my injuries had no caution tape or other warning indicating it was not to be 

used, I had seen it used by the other trades, and given lack of other access took this as an 

invitation to use it for access to my work.” Batton described his accident: “The stairway 

was not equipped with a landing, but rather with a plank; its unfinished stair riser pans 

were not filled with concrete, its riser height and tread depth was therefore not uniform, 

and it had unprotected sides and edges. While I have no specific recollection, I was 

probably carrying hand tools or possibly a short piece of rebar. While descending the 

unfinished stair riser pans which were partially filled with plywood and not with 

concrete, my foot snagged the edge of the pan causing me to land awkwardly on the 

plank, much lower than would have been a landing, caused my full weight of about 245 

pounds to twist my knee, and causing me to sustain the injuries which have so far led to 

two surgeries and kept me from returning to my trade.”
6

Batton also submitted an expert declaration from Gerald Fulghum, a safety 

engineer and certified safety professional. Fulghum opined the stairway was unsafe and 

did not comply with applicable safety regulations or industry custom and practice. The 

court overruled Alten‟s objection Nos. 1, 4, 5, 8, 16 and 17, which related to Fulghum‟s 

(1) description of the research he conducted into applicable codes and regulations, as well 

as construction industry practices (¶ 5), (2) opinions as to the scope of Alten‟s 

responsibilities based on industry custom and practice and safety regulations (¶¶ 8-9, 12), 

and (3) opinion the stairway was unsafe and violated the construction industry‟s custom 

and practice for worker safety and applicable regulations (¶¶ 20-21). The court sustained 

objection Nos. 10 through 15, which related to Fulghum‟s description of the content of 

codes and safety regulations (¶¶ 14-19), ruling “[i]t is the judge‟s duty to declare what the 

applicable law is.” The court also sustained objection No. 17, which related to 

Fulghum‟s opinion Alten‟s violations were “a substantial factor in causing . . . Batton‟s 

accident” (¶ 21), ruling this was “a factual question for the jury.”

In reply, Alten submitted additional deposition excerpts from Kwan Wo employee 

Situ, who testified he and others used ladders to gain access to the roof of the building.

3. The Trial Court‟s Order

After hearing argument, the trial court entered a written order granting summary 

judgment for Alten. The court ruled Batton‟s negligence causes of action were barred by 

the Privette doctrine, holding Alten “did not undertake to exercise control over the safety 

of the workplace in a manner that affirmatively contributed to [Batton‟s] injuries.” The 

court stated “[n]one of the temporary safety measures taken by [Alten] are claimed to 

have contributed to [Batton‟s] fall,” and “[t]he unfinished nature of the stairway was 

obvious and was not a latent hazardous condition.” Although there was “testimony that 

[Alten‟s] employees might have removed the caution tape . . . , that conduct was 

consistent with use of the stairs as scaffolding, it did not create a latent hazardous 

condition, and it did not relieve Galletti of the duty to ensure its employees had a safe 

workplace while they were using the stairs to install the rebar, or while accessing the 

second floor. Galletti could have instructed its employees to use ladders between the first 
7

and second floors instead of the unfinished stairway.” The court stated: “Under Privette

and its progeny, [Alten] has no tort liability for its passive conduct, and nothing [Alten] 

did relieved Galletti of its „duty to identify the absence of the safety guards required by 

Cal-OSHA regulations and to take reasonable steps to address that hazard.‟ [Citation.]” 

The court also concluded Batton was not an intended third party beneficiary of the 

contract between Alten and City.

The court entered judgment for Alten. Batton appealed.

III. DISCUSSION

A. Standard of Review

“The rules of review are well established. If no triable issue as to any material fact 

exists, the defendant is entitled to a judgment as a matter of law. [Citations.] In ruling on 

the motion, the court must view the evidence in the light most favorable to the opposing 

party. [Citation.] We review the record and the determination of the trial court de novo.” 

(Shin v. Ahn (2007) 42 Cal.4th 482, 499; accord, Aguilar v. Atlantic Richfield Co. (2001) 

25 Cal.4th 826, 843, 860.) The trial court‟s stated reasons for granting summary relief 

are not binding on the reviewing court, which reviews the trial court‟s ruling, not its 

rationale. (Kids’ Universe v. In2Labs (2002) 95 Cal.App.4th 870, 878.)

B. Negligence

1. The Privette Doctrine and Liability under Hooker

Our Supreme Court has summarized the Privette doctrine as follows: “Generally, 

when employees of independent contractors are injured in the workplace, they cannot sue 

the party that hired the contractor to do the work. . . . [¶] By hiring an independent 

contractor, the hirer implicitly delegates to the contractor any tort law duty it owes to the 

contractor‟s employees to ensure the safety of the specific workplace that is the subject of 

the contract.” (SeaBright Ins. Co. v. US Airways, Inc. (2011) 52 Cal.4th 590, 594 

(SeaBright), italics omitted; see Privette, supra, 5 Cal.4th at p. 696; Toland v. Sunland 

Housing Group, Inc. (1998) 18 Cal.4th 253, 256.) Accordingly, “subject to certain 

exceptions, when a general contractor hires a subcontractor, the general contractor is not 

liable for injuries that occur to the subcontractor‟s employees.” (Brannan v. Lathrop 
8

Construction Associates, Inc. (2012) 206 Cal.App.4th 1170, 1176 (Brannan); accord, 

Zamudio v. City and County of San Francisco (1999) 70 Cal.App.4th 445, 450.)

The Supreme Court described one such exception in Hooker. The Hooker court 

considered whether the hirer of an independent contractor could be held liable for injuries 

to the contractor‟s employee based on the hirer‟s “negligent exercise of retained control” 

over safety conditions at a worksite. (Hooker, supra, 27 Cal.4th at p. 201.) The court 

held that “a hirer of an independent contractor is not liable to an employee of the 

contractor merely because the hirer retained control over safety conditions at a worksite, 

but that a hirer is liable to an employee of a contractor insofar as a hirer‟s exercise of 

retained control affirmatively contributed to the employee‟s injuries.” (Id. at p. 202.) 

The liability of the hirer in such cases is not “ „ “ „vicarious‟ or „derivative‟ in the sense 

that it derives from the „act or omission‟ of the hired contractor,” ‟ ” but is direct. (Id. at 

p. 212; see also McKown v. Wal-Mart Stores, Inc. (2002) 27 Cal.4th 219, 222, 225 [hirer 

is directly liable to employee of independent contractor when hirer‟s provision of unsafe 

equipment affirmatively contributes to employee‟s injury].)

Imposing liability based on a hirer‟s negligent exercise of retained control is 

consistent with the “ „framework of delegation‟ ” underlying the Privette line of cases. 

(See Seabright, supra, 52 Cal.4th at pp. 594, 599-600; Kinsman v. Unocal Corp. (2005) 

37 Cal.4th 659, 671.) “If a hirer entrusts work to an independent contractor, but retains

control over safety conditions at a jobsite and then negligently exercises that control in a 

manner that affirmatively contributes to an employee‟s injuries, the hirer is liable for 

those injuries, based on its own negligent exercise of that retained control. [Citations.] 

Because the hirer actively retains control, it cannot logically be said to have delegated

that authority.” (Tverberg v. Fillner Construction, Inc. (2012) 202 Cal.App.4th 1439, 

1446 (Tverberg).)

In Hooker, the widow of a deceased crane operator who had been employed by a 

general contractor hired by the California Department of Transportation (Caltrans) to 

construct an overpass, sued Caltrans for negligently exercising its retained control over 

safety conditions at the jobsite. (Hooker, supra, 27 Cal.4th at p. 202.) The Caltrans 
9

construction manual provided Caltrans was responsible for obtaining the contractor‟s 

compliance with safety laws and regulations, and Caltrans‟s onsite engineer had the 

power to shut the project down because of safety conditions and to remove employees of 

the contractor for failing to comply with safety regulations. (Id. at pp. 202-203.) The 

crane operator retracted the crane‟s outriggers to allow Caltrans vehicles and other 

construction vehicles to use the narrow overpass. (Id. at pp. 202, 214.) When the crane 

operator then attempted to operate the crane without reextending the outriggers, the crane 

tipped over and the operator was killed. (Id. at p. 202.) The plaintiff alleged Caltrans 

was negligent in permitting traffic to use the overpass while the crane was being 

operated. (Id. at pp. 202-203, 214-215.)

The Supreme Court found the plaintiff in Hooker had raised triable issues of 

material fact as to whether Caltrans retained control over safety conditions at the 

worksite, but not as to whether Caltrans actually exercised the retained control so as to 

affirmatively contribute to the death of the plaintiff‟s husband. (Hooker, supra, 27 

Cal.4th at pp. 202, 215.) The court stated: “ „[A] general contractor owes no duty of care 

to an employee of a subcontractor to prevent or correct unsafe procedures or practices to 

which the contractor did not contribute by direction, induced reliance, or other 

affirmative conduct. The mere failure to exercise a power to compel the subcontractor to 

adopt safer procedures does not, without more, violate any duty owed to the plaintiff. . . .‟ 

[Citation.]” (Id. at p. 209.) The Hooker court stated, however, that an omission may 

constitute an affirmative contribution in some circumstances: “[A]ffirmative contribution 

need not always be in the form of actively directing a contractor or contractor‟s 

employee. There will be times when a hirer will be liable for its omissions. For example, 

if the hirer promises to undertake a particular safety measure, then the hirer‟s negligent 

failure to do so should result in liability if such negligence leads to an employee injury.” 

(Id. at p. 212, fn. 3.)

Applying these standards, the Hooker court found that, although Caltrans 

permitted vehicles to use the overpass while the crane was being operated, and the 

operator had a practice of retracting the outriggers to permit traffic to pass, Caltrans did 
10

not direct the crane operator to adopt that practice. (Hooker, supra, 27 Cal.4th at 

pp. 214-215.) Under those circumstances, the court held there was no evidence Caltrans 

affirmatively contributed to the crane operator‟s death. (Id. at p. 215.) Instead, “[t]here 

was, at most, evidence that Caltrans‟s safety personnel were aware of an unsafe practice 

and failed to exercise the authority they retained to correct it.” (Ibid.)

2. Triable Issues of Material Fact Preclude Summary Judgment

a. Retention of Control Over Safety Conditions

Batton raised triable issues of material fact as to whether Alten retained control 

over the safety of the unfinished stairway. (See Hooker, supra, 27 Cal.4th at pp. 202, 

215.) Batton presented evidence that, after Kwan Wo installed the steel stairway, closed 

it off with caution tape, and told Alten the unfinished stairway was not to be used, Alten 

took what the trial court referred to as “temporary safety measures” on the unfinished 

stairway and permitted its use at least for some purposes. There was evidence Alten 

installed a temporary guardrail, put temporary wood blocks in the stair pans, and placed 

wooden planks at the bottom of the stairs. Alten‟s workers may have removed the 

caution tape.1

Alten managers testified the guardrail and the blocks in the pans were routine 

safety practices for unfinished stairways. Alten took the measures because Galletti‟s 

ironworkers were working off the stairway, using it as “scaffolding” to install rebar on 

the adjacent wall. Alten‟s supervisor, Fitzgerald, testified the guardrail also was to 

protect “other trades, you know, just in case someone went up there. It‟s not a completed 

stairwell. If they fell off, or whatever. It‟s basically just for safety purposes because 

you‟re going to need it.”

 

1 As Alten notes, Kwan Wo employee Situ qualified his testimony on this point, stating 

he was “not sure” and could not be “positive” Alten‟s workers removed the tape. But the 

evidence Alten‟s workers took other measures (the guardrail, blocks in the step pans, and 

planks below the bottom step) permits an inference they removed the tape to gain access 

to the stairway to take those measures. In any event, the evidence Alten took the other 

measures is sufficient to raise triable issues of material fact.
11

This evidence allows an inference Alten retained control over the safety of the 

unfinished stairway, took measures to make it usable or available at least for some 

purposes, and permitted its use at least for those purposes. (See Tverberg, supra, 202 

Cal.App.4th at p. 1448 [general contractor‟s determination that certain temporary safety 

measures were sufficient allowed inference that general contractor “affirmatively 

assumed the responsibility for the safety” of workers in that portion of the worksite].)

Alten asserts SeaBright establishes a conclusive presumption Alten delegated to 

Galletti all responsibility for the workplace safety of Galletti‟s employees. To the extent 

Alten suggests SeaBright precludes a plaintiff from seeking to hold a hirer liable under a 

theory of negligent exercise of retained control, we disagree. The SeaBright court stated 

that, under Privette, a hirer “presumptively delegates” to an independent contractor the 

hirer‟s tort law duty to provide a safe workplace for the contractor‟s employees, including 

any tort law duty owed to the contractor‟s employees to comply with safety statutes and 

regulations. (SeaBright, supra, 52 Cal.4th at pp. 600, 601, 603.) But the SeaBright court 

expressly reaffirmed the Hooker rule that a hirer may be liable to a contractor‟s employee 

if the hirer retains control over safety conditions and negligently exercises that control in 

a manner that affirmatively contributes to the plaintiff‟s injury. (SeaBright, at pp. 599, 

601.)

b. Affirmative Contribution to Injury

Batton also raised triable issues of material fact as to whether Alten exercised its 

retained control so as to affirmatively contribute to Batton‟s injury. (See Hooker, supra, 

27 Cal.4th at pp. 202, 215.) A jury could find that Alten, by installing temporary safety 

measures, exercised control over safety conditions. The evidence also permits an 

inference Alten exercised its control in a negligent manner, by implementing measures 

that were inadequate for the safe temporary use of the unfinished stairway. Batton‟s 

expert, Fulghum, opined the unfinished stairway was unsafe and violated industry custom 

and practice for worker safety. Alten‟s supervisor, Fitzgerald, testified the stairway 

lacked a proper footing. Batton stated in his declaration that “[t]he stairway was not 

equipped with a landing, but rather with a plank; its unfinished stair riser pans were not 
12

filled with concrete, its riser height and tread depth was therefore not uniform, and it had 

unprotected sides and edges.”

In our view, this evidence supports an inference of affirmative contribution in two 

ways. First, by installing some temporary safety measures and permitting use of the 

unfinished stairway without additional measures (such as a temporary bottom step), Alten 

arguably determined which safety measures were necessary. In Tverberg, Division Four 

of this court concluded that a similar determination by a general contractor allowed an 

inference of affirmative contribution. In that case, which involved an expansion project 

at a commercial fuel facility, a subcontractor dug holes for “ „bollards,‟ concrete posts 

intended to prevent vehicles from colliding with fuel dispensers.” (Tverberg, supra, 202 

Cal.App.4th at p. 1442.) Each hole was four feet wide and four feet deep and was 

marked with stakes and safety ribbon. (Ibid.) The plaintiff, an independent contractor 

hired by a different subcontractor performing unrelated work near the bollard holes, fell 

into one of the holes and was injured. (Id. at pp. 1442-1443.)

Division Four found the evidence allowed an inference of affirmative contribution 

in several ways.2 (Tverberg, supra, 202 Cal.App.4th at pp. 1447-1448.) One basis for 

finding affirmative contribution was the general contractor‟s determination there was no 

need to cover or barricade the bollard holes. (Id. at p. 1448.) The general contractor‟s 

employee in charge of the jobsite testified he concluded the stakes and safety ribbon 

constituted sufficient protection. (Ibid.) The appellate court, noting its duty on summary 

judgment to construe the evidence in favor of Tverberg, stated the evidence “allows an 

inference that [the general contractor] affirmatively assumed the responsibility for the 

safety of the workers near the bollard holes, and discharged that responsibility in a 

negligent manner, resulting in injury.” (Ibid.) Similarly, the evidence in this case, 

construed in favor of Batton, allows an inference Alten affirmatively assumed the 

responsibility for the safety of workers using the unfinished stairway, and discharged that 

 

2 The California Supreme Court reversed an earlier decision by Division Four in 

Tverberg that involved different issues. (See Tverberg v. Fillner Construction, Inc.

(2010) 49 Cal.4th 518, 521-522, 528-529; Tverberg, supra, 202 Cal.App.4th at p. 1444.)
13

responsibility in a negligent manner, resulting in Batton‟s injury. (See ibid.; see also 

Browne v. Turner Construction Co. (2005) 127 Cal.App.4th 1334, 1345-1346 [the 

defendants undertook to provide safety systems and devices and then withdrew them]; 

Ray v. Silverado Constructors (2002) 98 Cal.App.4th 1120, 1128-1129, 1133-1134 

[under Hooker, omission can constitute affirmative contribution].)

Alten argues Tverberg is inapposite because the plaintiff in that case asked the 

general contractor to cover the bollard holes prior to his injury, while Batton did not raise 

with Alten any concerns about the safety of the unfinished stairway. But, as noted, the 

Tverberg court found several grounds for a finding of affirmative contribution. 

(Tverberg, supra, 202 Cal.App.4th at pp. 1447-1448.) One of these was based on 

Tverberg‟s request that the general contractor cover the bollard holes. The general 

contractor‟s response that the necessary equipment was not available allowed an 

inference that the general contractor agreed to cover the holes and then failed to do so. 

(Id. at p. 1448.) A separate potential basis for liability in Tverberg was the general 

contractor‟s determination that the stakes and safety ribbons provided sufficient 

protection (and therefore it was not necessary to cover or barricade the bollard holes). 

(Ibid.) We relied on this factor in our discussion above.

A second basis on which a reasonable jury could find affirmative contribution in 

this case is that the temporary safety measures Alten took contributed to Batton‟s injury. 

The wood blocks Alten placed in the stair pans did not completely fill the pans; instead, 

there were gaps on one side of the steps. Batton‟s declaration supports an inference the 

unfilled condition of the stair pans contributed to his injury. Batton stated the 

“unfinished stair riser pans were not filled with concrete, its riser height and tread depth 

was therefore not uniform, and it had unprotected sides and edges. . . . While descending 

the unfinished stair riser pans which were partially filled with plywood and not with 

concrete, my foot snagged the edge of the pan causing me to land awkwardly on the 

plank . . . .” As Alten notes, Batton does not provide a detailed explanation of precisely 

how his foot snagged the edge of the pan. But his declaration, which we construe in his 

favor as the party opposing summary judgment (see Shin v. Ahn, supra, 42 Cal.4th at 
14

p. 499), is sufficient to suggest that, because the pan was not completely filled, Batton 

caught his foot, tripped, or lost his footing. This evidence allows an inference that Alten, 

by placing wood blocks that only partially filled the pans, negligently exercised its 

retained control over the safety of the stairway in a manner that affirmatively contributed 

to Batton‟s injury.

Alten asserts Batton‟s statement he snagged his foot is “simply not credible.” 

Alten argues this statement is inconsistent with the injury reports prepared by Batton and 

his supervisor, Wheeler. The reports state the bottom step of the unfinished stairway was 

18 to 24 inches off the ground, and Batton fell when stepping down from the bottom step 

to the ground; one of Wheeler‟s reports states the height of the drop “caused [Batton] to 

misjudge the ground causing him to fall.” The brief descriptions in the reports do not 

mention Batton snagged his foot on the stair pan.

A court generally may not weigh the credibility of a declaration submitted in 

opposition to summary judgment. (AARTS Productions, Inc. v. Crocker National Bank

(1986) 179 Cal.App.3d 1061, 1065; see also Estate of Housley (1997) 56 Cal.App.4th 

342, 359-360.) The short descriptions of Batton‟s accident in the reports do not establish 

that the more detailed account in his declaration is “facially incredible as a matter of law” 

so as to justify disregarding it on summary judgment. (Estate of Housley, supra, 56 

Cal.App.4th at p. 360.)

Alten also states Batton “refused to submit to a deposition.” Whatever the merits 

of the parties‟ dispute on this issue (which we need not address),3 it provides no basis for 

this court to disregard Batton‟s declaration. Alten did not object to, and the trial court did 

not exclude, the portion of Batton‟s declaration describing his accident (based on the 

deposition dispute or any other ground), so we will consider it. (See Merrill v. Navegar, 

 

3 Alten did not depose Batton prior to moving for summary judgment in October 2011; 

the summary judgment hearing was set for February 15, 2012. On January 11, 2012, 

Alten noticed Batton‟s deposition for January 25; Batton‟s counsel responded he would 

be unavailable; Batton did not appear for the deposition; and Alten filed a motion to 

compel, which was set for April 2012. When the court granted summary judgment, it

vacated the hearing on the motion to compel.

Inc. (2001) 26 Cal.4th 465, 476 [reviewing court considers all evidence submitted by 

parties in connection with summary judgment motion, except evidence the trial court 

properly excluded].)

Alten‟s remaining arguments do not persuade us summary judgment is proper. 

Alten cites Brannan, but that case is distinguishable. In Brannan, Division One of this 

court held a general contractor was not liable under Hooker to a masonry subcontractor‟s 

employee who was injured trying to gain access to his work area by crossing a plaster 

scaffold placed by another subcontractor. The general contractor did not direct the 

plaintiff‟s work and did not tell him to gain access the way he did. (Brannan, supra, 206 

Cal.App.4th at pp. 1178-1179.) There also was no evidence the general contractor knew 

before the plaintiff‟s injury that he or other workers were climbing over the scaffolding in 

the manner they did, or that the practice posed a safety hazard. (Id. at p. 1179.) Under 

those circumstances, the general contractor‟s acts of scheduling jobsite activities, 

allowing the scaffolding to remain in place, and failing to call a rain day did not 

constitute affirmative contribution under Hooker. (Brannan, at pp. 1178-1180.) Here, in 

contrast to Brannan, Alten itself took steps to modify and make usable the stairway 

installed by Kwan Wo, and was aware it was being used. We conclude Alten‟s actions 

and the other evidence presented raise triable issues of fact as to whether Alten 

affirmatively contributed to Batton‟s injury.

Alten contends Galletti breached its tort and contractual duties by failing to 

provide Batton alternative means of access to the second floor (such as ladders), and 

Batton was negligent in using the conspicuously unsafe stairway.4 But the alleged 

negligence of other parties does not preclude a finding that Alten‟s negligent exercise of 

retained control affirmatively contributed to Batton‟s injuries. (See McKown v. 

Wal-Mart Stores, Inc., supra, 27 Cal.4th at pp. 222-223, 225-226 [hirer liable to 

employee of independent contractor when hirer‟s provision of unsafe equipment 

 

4 Batton agrees the stairway was not a latent hazardous condition of which Alten had a 

duty to warn Batton, and he does not seek to impose liability on that basis. (See Kinsman 

v. Unocal Corp., supra, 37 Cal.4th at pp. 674-675.)
16

affirmatively contributed to employee‟s injury; “[a]dmittedly, [hirer] was not the only 

one at fault, but then the jury‟s verdict reflected that”].)

Alten also notes Fitzgerald‟s testimony that Galletti‟s workers were allowed to use 

the stairway as scaffolding, but not to gain access to the second floor. But the evidence 

allows an inference the use of the stairway was not so limited. Fitzgerald testified “we 

had danger tape” at the top and bottom of the stairs, and “[n]o one was to use [the 

stairway] as access,” but he acknowledged the tape had been removed and was lying on 

the ground. Fitzgerald also suggested others might have used the stairway, stating the 

guardrail was for the protection of “other trades . . . just in case someone went up there,” 

or for “[t]rades and whoever walks onto the site.” Batton stated in his declaration that he 

saw “other trades” using the stairway. Batton also presented evidence the city inspector 

used the stairway to gain access to the second floor, and Alten‟s backup supervisor may 

have done so. A reasonable jury could conclude use of the stairway was not limited to a 

specific group of workers performing a specific task.

Batton has raised triable issues of material fact as to whether Alten is liable on a 

theory of negligent exercise of retained control.5 Accordingly, Alten is not entitled to 

summary adjudication as to Batton‟s negligence causes of action.6

 

5 Because the evidence in the record (including Batton‟s declaration, the deposition 

excerpts, and the portions of Fulghum‟s declaration admitted by the trial court) raises 

triable issues of material fact, we need not address Batton‟s argument the trial court erred 

by sustaining objections to other portions of Fulghum‟s declaration, such as those 

describing the content of statutory and regulatory provisions (¶¶ 14-19), and setting forth 

Fulghum‟s opinion that Alten‟s actions caused Batton‟s accident (¶ 21).

6 Although stated as a separate cause of action in Batton‟s complaint, we construe his 

negligence per se theory as part of his negligence cause of action. (See Millard v. 

Biosources, Inc. (2007) 156 Cal.App.4th 1338, 1353, fn. 2 [“[T]he doctrine of negligence 

per se is not a separate cause of action, but creates an evidentiary presumption that affects 

the standard of care in a cause of action for negligence. [Citation.]”]; accord, Johnson v. 

Honeywell Internat. Inc. (2009) 179 Cal.App.4th 549, 555.) As to both negligence 

“causes of action,” Alten sought summary adjudication on the basis of the delegation-ofduty rationale we discuss above. Triable issues of material fact preclude summary 

adjudication on that issue.

C. Contractual Claim as Third Party Beneficiary

Batton argues Alten owed him a contractual duty to keep the workplace safe, 

contending he was a third party beneficiary of Alten‟s general contract with City. For a 

third party to qualify as an intended beneficiary under a contract, there must be evidence 

the contracting parties intended to benefit that third party, “and their intent must appear 

from the terms of the contract. [Citations.] While the [intended] beneficiary need not be 

named in the contract, he must be a member of a class referred to and identifiable therein. 

[Citations.]” (Kirst v. Silna (1980) 103 Cal.App.3d 759, 763.) Other persons, termed 

incidental beneficiaries, may fortuitously benefit from the performance of the contract, 

but they have no legal right to enforce its terms. (Ibid; see also 1 Witkin, Summary of 

Cal. Law (10th ed. 2005) Contracts, § 689, p. 776.)

Here, the general contract states it is an agreement between Alten and City. The 

trial court correctly concluded paragraph 6.2.D. of the General Conditions in Section 

00700 (a provision relied on by Batton in opposing summary judgment) does not support, 

and indeed undercuts, Batton‟s claim he is an intended beneficiary of the contract. 

Paragraph 6.2.D. provides: “[Alten‟s] duties and responsibilities under paragraph [sic] of 

this Section 00700 are for the benefit of City . . . and also for the benefit of such other 

contractors and utility owners working at the Site to the extent that there are comparable 

provisions for the benefit of [Alten] in the direct contracts between City . . . and such 

other contractors and utility owners.” (Italics added.) It is undisputed Galletti‟s 

subcontract was only with Alten; Galletti had no direct contract with City. Paragraph 

6.2.D. confers no enforcement rights on Galletti or its employees.

Alten argues further that paragraph 6.2.D. specifies the intended beneficiaries of 

the General Conditions (Section 00700) as a whole, thus precluding Batton from relying 

on other provisions to show he is an intended beneficiary. Paragraph 6.2.D. arguably is 

ambiguous on this point. It states Alten‟s “duties and responsibilities under paragraph 

[sic] of this Section 00700” are for the benefit of City and other contractors that have 

direct contracts with City. Paragraph 6.2.D. thus may only designate the intended 
18

beneficiaries of some unspecified paragraph of Section 00700, rather than of Section 

00700 as a whole.

We need not resolve this question, because the other provisions cited by Batton do 

not support his claim he is an intended beneficiary. Batton cites paragraphs 8.1.B. and 

8.3 of the General Conditions, which provide Alten must “supervise, inspect, and direct 

Work competently and efficiently” (¶ 8.1.B.), and “shall have sole care, custody, and 

control of the Site and its Work areas” (¶ 8.3). These and related provisions allocate, as 

between Alten and City, control of the site and the work. Alten must supervise and direct 

the work to ensure it complies with contractual requirements (¶ 8.1.B.); the work is to be 

performed under City‟s representative‟s “general observation and administration” 

(¶ 8.2.A.); and Alten must provide access for City and its employees to inspect and 

perform work (¶ 8.3). These provisions provide no basis for finding Batton is an 

intended beneficiary.

Batton also cites paragraphs 16.3.B. and 16.3.C. of the General Conditions, which 

provide Alten is to be “fully responsible for the safety of its and its Subcontractors‟ 

employees, agents and invitees on the Site” (¶ 16.3.B.), and must “provide safe means of 

access to all places at which persons may at any time have occasion to be present” 

(¶ 16.3.C.). But Batton cites no authority holding these or similar provisions in a general 

contract establish a subcontractor‟s employee is an intended beneficiary entitled to sue 

the general contractor for breach of contract. Indeed, courts have refused to find similar 

contractual provisions established a hirer had a contractual duty to an injured employee 

of a subcontractor. In Zamudio v. City and County of San Francisco, supra, 70 

Cal.App.4th at page 453, this court held a contractual provision delegating the owner‟s 

safety responsibilities to the general contractor did not create a duty of care upon the 

general contractor toward the subcontractor‟s employee. In West v. Guy F. Atkinson 

Constr. Co. (1967) 251 Cal.App.2d 296, 302 (West), the court held provisions in the main 

contract between the general contractor and the state requiring the contractor to comply 

with safety laws, provide safeguards, and take actions to protect employees on the job 

were not intended to create a third party beneficiary contract giving employees of the 
19

subcontractor the right to sue at common law in addition to their worker‟s compensation 

rights. Instead, the provisions were intended to “underline the fact that [the general 

contractor], by subcontracting, was not to be relieved of any obligation owed to the state 

and the public.” (Ibid.) The West court reached this conclusion even though a clause in 

the main contract provided that “ „all persons engaged in the work of construction will be 

considered as employees of the [c]ontractor.‟ ”

7 (Ibid.) Here, the cited provisions of the 

general contract, whatever their relevance to Batton‟s negligence cause of action, do not 

establish Batton is an intended beneficiary entitled to pursue an independent cause of 

action for breach of the general contract.

IV. DISPOSITION

The order granting summary judgment and the judgment are reversed. The trial 

court is directed to enter a new order denying summary judgment, denying summary 

adjudication as to the negligence causes of action, and granting summary adjudication as 

to the contract cause of action. The parties shall bear their own costs on appeal.

 

7 Batton, citing Alten‟s temporary safety measures, notes a court may consider the 

subsequent conduct of the parties in construing an ambiguous contract. (See Spinks v. 

Equity Residential Briarwood Apartments (2009) 171 Cal.App.4th 1004, 1024.) We 

conclude the contractual provisions at issue are unambiguous and do not make Batton an 

intended beneficiary of the contract.
