Acciona Case Study 2
PART A
1. What is the basis in law for the claim by Acciona?
According to Acciona, one of the essential terms of the contract with Transport for NSW had
been the handling of utility services in the course of contraction of the light rail line by
Ausgrid. Acciona claims that it would not have accepted the bid or proceeded with
construction had it known that Ausgrid had not agreed to deal with the electricity cables
beneath its route line. Acciona states that it had been “led to believe” that Ausgrid would
handle the electricity cables which suggest this term was an implication to the contract and
not expressly worded.
One of the founding principles of contract law which are reflected in common law and in
statute is that; in order for a contract to be valid, there should be acceptance (Bailey, 2011).
According to Article 2.1 of the Unidroit Principles, the “a contract may be concluded either
by the acceptance of an offer or by conduct of the parties that is sufficient to show
agreement”. In Hayden Young Ltd v Laing O’Rourke Midlands Ltd [2008] EWHC 1016, the
court was of the opinion that acceptance should occur through conduct which objectively
reflected a final and unconditional assent to the offer made. Silence would not qualify as
assent unless accompanied by the conduct from the parties that would be construed as
acceptance.
Another issue to consider in determining the claim by Acciona is the concept of implied
terms. A term can be implied by law, or based on the intention of the parties (Bailey, 2011).
Implied terms may raise issues of ambiguity. In Codelfa Construction Pty Ltd v State Rail
Authority NSW (1982) 149 CLR 337, the plaintiff won a tender to excavate tunnels for a new
railway line from the Commissioner for Railways at the time. According to the contract, the
plaintiff was obligated to work three shifts a day for seven days a week. The work in itself
was noisy which led to several injunctions being raised by residents against the plaintiff and

Acciona Case Study 3
subsequently led to the reduction of workable hours leading to additional costs and lost
profits. The plaintiff made a claim against the Commissioner citing that there was an implied
term that the work would not be subject to injunctions and that the contract had been
frustrated based on these injunctions. The High Court in the matter held that there was no
implied term as it could not be determined whether the parties would have agreed if they had
expressly considered the matter. As such, external evidence could not be relied on to adjust
the written terms of the contract. In B& B Constructions (Aust) Pty Ltd v Brian A Cheeseman
& Association Pty Ltd (1994) 35 NSWLR 22 however, the court held that extrinsic evidence
could be used to determine the intent or parties where ambiguity arose.
The final issue to consider in determining Acciona’s claim is whether the acceptance
reflected genuine consent to contract; that is it was not given based on a mistaken belief, a
misrepresentation, under duress or undue influence or on the basis of unconscionable
behaviour. According to section 18 of the Australian Consumer Law 2010(Cth), a business or
individual in the in the course of trade should not engage in conduct that would mislead or
deceive or is misleading or deceptive to another party as this would amount to
unconscionable behaviour which is, in essence, a breach of contract. Unconscionable conduct
refers to behaviour that is unfair, or unreasonable as was illustrated in Commercial Bank of
Australia Ltd v Amadio (1983) 151 CLR 447. In this case, the plaintiffs were aware that the
defendants spoke little English and as such were not fully aware of the implications of acting
as guarantors to a contract between the bank and their son. The plaintiffs’ knowledge and
procession with the contract despite the knowledge of the disadvantage caused to the
defendant amounted to unconscionable conduct prohibited under s 18. Behaviour is
considered misleading or deceptive if it induces or is likely to induce an error on the parties
that rely on it (Parkdale Custom Built Furniture Pty Ltd v Puxu Pty Ltd , (1982) ).
Additionally, deceptive and misleading conduct can be considered as a breach of good faith

Acciona Case Study 4
which is a term implied under common law as illustrated in Burger King Corporation v
Hungry Jack’s Pty Ltd [2001] NSWCA 187.
Based on the legislation and precedence above, Acciona’s claim against Transport for NSW
is grounded on the fact that Acciona accepted the terms of the contract on terms which were
implied by the defendant’s conduct which can be argued to be misleading or deceptive as it
led to the plaintiff acting in a manner that generated extra costs and loss of profits.
2. What would have to be established by Acciona to support their claim?
The first step to supporting their claim is proving the existence of a contract by establishing
the elements of a contract which include: the offer, acceptance, consideration, intent to be
legally bound, capacity and legality (Bailey, 2011).
In order to support their main claim, Acciona has to prove that the term relied on was an
implied term in order to establish that it was misleading or deceptive. The court in BP
Refinery (Westernport) Pty Ltd v Shire of Hastings [1977] UKPC 13, outlined that for a term
to be considered implied it must be reasonable and equitable, necessary to give the contract
effectiveness, obvious, capable of clear expression and not contradictable to the contract’s
express terms. Additionally, as aforementioned, in order to be used as a claim for damages,
the innocent party must demonstrate that the misleading or deceptive conduct of the other
party or their agent was relied upon and used in a manner that affected the innocent party’s
behaviour with respect to the contract in question (Bailey, 2011). Additionally, the reliance
must be reasonable; an objective test is employed to determine the reasonableness of the
reliance (Campbell v Backoffice Investments Pty Ltd, [2009]; Bailey, 2011).
3. What would Transport for New South Wales have to establish in opposition of their
claim and any counterclaim?
As illustrated in Abigroup Contractors Pty Ltd v Sydney Catchment Authority [2004]
NSWCA 270, a corporation can be found to have engaged in conduct that is misleading or

Acciona Case Study 5
deceptive even if it acts honestly and reasonably. Therefore, acting honestly cannot be
construed as a defence or opposition to the claim if the plaintiff can satisfy the conditions
required to prove that the conduct was misleading and deceptive. The defendant can however
challenge the validity of the term as an implied term based on the criteria outlined in BP
Refinery (Westernport) Pty Ltd v Shire of Hastings [1977] UKPC 13 as well as the
reasonableness of the defendant’s reliance on said term and contract based on the test
employed in Campbell v Backoffice Investments Pty Ltd, [2009].
As a counterclaim, Transport for New South Wales can rely on the doctrine of promissory
estoppel to compel Acciona to complete the contract. As stated in the facts of the case, the
delay by Acciona has dire consequences on the economic stability of the city due to the state
of the CBD. The underpinnings of the concept of promissory estoppel in Australia can be
illustrated in the case of Waltons Stores (Interstate) Ltd v Maher (1988) 164 CLR 386. The
plaintiff in the case sought to establish a store and as such entered into negotiations to
demolish a building and build a new one. The plaintiff’s legal party sent a redrafted lease to
the defendant's team with the negotiated amendments. The building was subsequently
demolished, the plaintiff, however, claimed that there had been no lease of exchange of
contract. The court held that the plaintiff’s behaviour was unconscionable as they adopted a
course of inaction despite knowing the detriment in cost that the defendant would incur by
proceeding with construction. The court held that the defendant, Maher, could rely on
promissory estoppel as both a sword and a shield and that Walton’s could be estopped from
retreating from the promise to complete.
In the current case, the urgency for completion is illustrated by the financial an economic
costs the city stands to suffer in the current state. Acciona has also refused to provide a
reasonable timeline for completion to the Transport ministry. The Trasport for NSW can rely

Acciona Case Study 6
on this as an illustration of the unconscionability arising form Acciona’s behaviour and use
the doctrine of promissory estoppel as a counterclaim to Acciona’s suit.
4. What is required for each side to prepare for the hearing and what sort of witnesses
are required?
The claimant is required to file summons which are accompanied by a Statement
summarising their issues of contention (Bailey, 2011). They should indicate whether other
dispute resolution methods such as arbitration or mediation have been attempted. The defence
files a defence and counterclaim if any. Each party should indicate their list of witnesses.
In this case, expert witnesses are essential to explain procurement processes and construction
management to the court in order to determine the detriment of the actions of either of the
parties to the success of the contract. The construction manager would play an effective role
as an expert witness as their essential role is managing and coordinating operations at the site
which includes controlling performance and overseeing the adherence to contractual
obligations at the site such as working hours or working manners (Bailey, 2011).
5. Having regard to the problems encountered in this case, what procedures would you
formulate to cover to avoid problems of amendments in the course of construction
and advice about the resolution of technical disputes and use of experts?
According to Victoria University of Manchester v Hugh Wilson & Lewis Womersley (1984) 2
Con LR 43 and Equitable Debenture Assets Corporation Ltd v William Moss Group Ltd
(1984) 2 Con LR1, having a written document in clear, simple and straight to the point
language which encompasses all the specification of the contract is essential towards
protection against legal issues arising from ambiguity in contracts. The clarity and
conciseness which accrues from adopting these qualifications in construction contracts ensure
that the end results of the project in question can be realistically achieved by all the parties
involved that is, the builder, the site architect, the proprietor or their agent. Therefore in order

Acciona Case Study 7
to avoid future problems of ambiguity and amendments, it is essential that the parties engage
in the development of a clear and concise contract.
With respect to the resolution of disputes, there are various avenues of dispute resolution in
construction law. These include Arbitration, Mediation, Adjudication, Expert Determination
and Litigation (Bailey, 2011). Usually, standard construction contracts are equipped with an
arbitration clause which requires that parties subject themselves to an arbitration process prior
to engaging a court of law to solve the rising issues (George, 2016). Where parties include an
arbitration clause in their contract, the construction contract and the Commercial Arbitration
Act 2010 will inform the process of arbitration by defining the arbitrator’s role and the
procedure (George, 2016). The advantage is that the parties can choose an arbitrator who has
technical experience in construction. Another approach to dispute resolution with respect to
technical disputes would be litigation. With the introduction of specialist construction and
building lists in most State and Federal courts, courts have the expertise to undertake
technical disputes in construction cases (Pickering, 2016).
In construction law, experts can be used for dispute resolution in expert determination or as
expert witnesses. Expert determination is suitable in resolving issues between parties which
are of a more specialist or technical nature. The process is consensual as parties determine
before commencing the process whether they will be bound by the expert’s decision (Quick
& Chenoweth, 2017). Unlike arbitration, expert determination is purely a contractual
creature established through an expert determination agreement and as such lacks statutory
support (Bailey, 2011). Usually, the scope of issues brought before an expert is technical
issues as aforementioned, however, the agreement may expand the scope to include non-
technical issues such as costs for determination. It is essentially viewed as a faster and more
effective way of resolving technical or specialised disputes (Heart Research Institute Ltd v
Psiron Ltd , [2002]; Bailey, 2011) as opposed to litigation.

Acciona Case Study 8
Summarily, in order to avoid future problems, a clear and concise written contract will be
essential so as to curtail ambiguity. Additionally, an expert determination agreement should
be considered as it is the most suitable and effective for technical disputes. Arbitration and
litigation, however, are both relatively advantageous to technical dispute resolution.

PART B
The Building and Construction Industry Security of Payment Act (Vic) 2002, also known as
the SOP (Vic) Act, is a piece of legislation enacted to ensure contractors and sub-contractors
engaged in a contraction contract are duly paid (VBA, 2018). The SOP (Vic) Act was enacted
to ensure a balance of power between contractors and principals as previously, the principle
had enjoyed superior bargaining power which was illustrated through delays or dispute in
payments which could culminate in contractors settling for lower amounts to ensure cash
flow. The main concern of the SOP (Vic) Act as provided for under Paragraph 1 is to ensure
persons who engage in construction work either directly or by providing necessary supporting
goods and services receive their entitled progress payments.
Essentially, the right to payment is expressly provided for under s 9 of the SOP Act (Vic)
2002 which states that on and from each reference date, those who are engaged to carry out
contraction work or supply related goods or services as defined by the Act are entitles to
payment which is calculated in reference to the pre-determined date. The amount to be paid is
calculated on the guidance of the contract based on the work carried out or the commodities
supplied. Section 10B goes further to outline amounts that are excluded from the calculation
of progressive payments. They include variations (except claimable variations),
compensation for latent conditions, time-related costs and regulatory changes, claims in
damages for breach of contract, claims arising in law other than those covered under the
contract and any other amount considered as an excluded amount in regulations. In Dualcorp
Pty Ltd v Remo Constructions Pty Ltd [2009] NSWCA 69, claims dealt with in adjudication
over the same works are no longer valid payment claims and as such are excluded amounts.
The SOP (Vic) Act goes further to provide criteria to guide the nature and scope of details to
be included in constructing and executing a payment claim under part 3. Section 14 (2)
provides that a payment claim should be made in the prescribed form, with the prescribed

Acciona Case Study 10
information, if any is outlined in the contract. Further, the claim must identify the
construction work or commodities supplied to which the payments are to be made. It should
also indicate the claimed amount and expressly recognise that it was made under the SOP
(Vic) Act 2002. Claims under s 29(4) with respect to suspension of work can also be made
under this claim but not the excluded amounts described above.
In Gantley Pty v Ltd v Phoenix International Group Pty Ltd [2010] VSC 106, the court,
although deciding the case under the old Act, highlighted some opinions with respect to the
new Act. It outlined that the claim must describe the work or commodity adequately so that
the principle can understand the basis of the claim. In reaffirming the criteria set in Gantley v
Phoenix [2010], the court in Krongold Constructions (Aust) Pty Ltd v SR & RS Wales Pty
Ltd [2016] VSC 94 challenged the details in the payment claim issued by the defendant
stating that they had failed to meet the basic criteria under s 14 of the SOP (Vic) Act. This is
because the construction work on which the claim was based had not been sufficiently
described.
Once a claim has been made, the respondent who is served with the claim replies by way of a
payment schedule identifying the claim it refers to and the amount to be paid, that is, the
scheduled amount. The respondent reviews the claim and in the schedule outlines the
amounts which they consider are excluded amounts and therefore not payable. The prescribed
form and prescribed information if any should be included. If a respondent fails to provide a
payment schedule within the stipulated time in the contract or within 10 business days after a
payment claim is made, as provided for under s 12 of the SOP (Vic) 2002, the respondent is
liable for the claimed amount.
In Lucas Stuart Pty Ltd v Hemmes Hermitage Pty Ltd [2010] NSWCA 283, it was held that if
the defences to be raised within the payment schedule are not raised within the time
stipulated in the Act, the responded will lose the right to raise them as a defence at an

Acciona Case Study 11
adjunction. An in-depth illustration of the payment process and the consequences of delay is
illuminated in the Bitannia Pty Ltd & Anor v Parkline Constructions Pty Ltd [2006] NSWCA
238 case. In the course of construction, the defendant in the case had been submitting
payment claims to an architect appointed by the plaintiff who oversaw the general
administration of the contract as an agent for Bitannia. The first two claims were submitted to
the architect who subsequently provided payment schedules rejecting the claims. The third
claim, however, was issued to a general manager of a company in association with the
plaintiff. Essentially, a payment schedule in reference to this claim was not issued and the
time stipulated by law lapsed. The defendant, therefore, instituted a claim to recover the
amount owed as debt. Essentially, the failure to issue a payment schedule would mean that
the plaintiff had lost their right to dispute the claim and would be liable to pay. However, as
the premise of the case before the court was misleading and deceptive conduct under s 52 of
the Trade Practices Act the provisions of the TPA would prevail over the SOP (Vic) Act 2002
as commonwealth law prevailed over state law.
Any dispute arising as a result of the payment process should be referred to an adjudicator
based on the provisions of ss 18 to 28 of the SOP (Vic) Act 2002. As illustrated in Hickory
Developments Pty Ltd v Schiavello (Vic) Pty Ltd & Anor [2009] VSC 156, an adjudicator has
the power and discretion to determine whether the claim for payment has been validly
referred for adjudication based on the provisions of the Act. Additionally, Grocon
Constructors v Planit Cocciardi Joint Venture [2009] VSC 339 outlines that, the
adjudicator’s decision is not entirely final as it can be reviewed by a Court of law by a writ of
certiorari which quashes the adjudicator’s decision.
Based on the discussion above, Acciona can make claims for progressive payment for
construction work and any commodities supplied. As such, the claimable amount includes the
construction cost of $1.07 billion and $ 175 million in overhead and management costs as

Acciona Case Study 12
these are expenses incurred directly from construction work. However, the claims for
compensation in damages of up to $147 million would fall under excluded amounts. Acciona
would formulate and send a detailed payment claim to the Transport for NSW detailing the
amounts claimed and highlighting the statute under which the claims are being made.
Transport for NSW is then expected to issue a payment schedule within the stipulated period
citing how much it is willing to pay and why if it is less than the claimed amount. Where a
dispute arises it will be subject to adjudication however as there is an ongoing claim for
misleading and deceptive conduct, the respondent may not lose their defence against the
claim for payment if the period for issuing a schedule expires.
