Extensions Of Time, Concurrent Delays, And Causation: City Inn v Shepherd Judicial Guidance From The UK Courts At Long Last
Concurrent delay is an issue that arises on most
construction projects. Put simply, the issue arises where a
project has not been completed on time because of two or more
delaying events that operate at the same time—one of the
delaying events is the responsibility of the project owner and
the other is the responsibility of the contractor. For example,
an owner instructs a contractor to undertake additional work
via a change order. The parties acknowledge that completion of
the project will be delayed because of the extra work. However,
at the time of carrying out the additional work, the contractor
has deliberately reduced its labor resources for reasons
unrelated to the variation but, in the event, compound the
delay effect of the variation. The delay caused by the
additional work and the insufficient resources run concurrently
and delay completion of the project by one month.
The question to be answered is, who is responsible for the
one-month delay to completion of the project. Is it the
contractor? In that case, the owner will be entitled to claim
its delay-related damages, which are usually in the form of
liquidated damages. Or is it the responsibility of the owner?
If so, and depending on the terms of the contract between the
parties, the contractor will be relieved from liquidated
damages by extending the time for completion of the project and
may also recover its delay-related losses, such as
prolongation, disruption, and acceleration costs. Or is
responsibility to be shared between the parties? If
responsibility is to be shared, upon what basis is this
determined?
Despite the prevalence of concurrent delays on construction
projects, there has been a dearth of judicial guidance in
Commonwealth jurisdictions on how to resolve the vexing
question of responsibility. The only substantial insight was
found in the English decision of Henry Boot Construction
(UK) Ltd v Malmaison Hotel (Manchester) Ltd [1999] 70 Con
LR 32. The judgment noted the common ground between the parties
that:
it is agreed that if there are two concurrent causes of
delay, one of which is a relevant event [e.g., the
owner's change order], and the other is not
[e.g., the contractor's insufficient resources],
then the contractor is entitled to an extension of time for
the period of delay caused by the relevant event
notwithstanding the concurrent effect of the other
event." (Also see the subsequent decision in
Royal Brompton Hospital NHS Trust v Hammond and
Others (No. 7) [2001] 76 ConLR 148, where it was held
that the contractor "would be entitled to extensions of
time by reason of the occurrence of the relevant events
notwithstanding its own defaults.")
However, it was not necessary in Malmaison for the
court to assess the period of delay caused by the relevant
event. As such, the case stopped short of providing practical
assistance on how the extension of time should be quantified or
measured in circumstances where there are concurrent delays to
project completion.
Possible bases of measurement advanced at an academic level
and within the construction industry include the following
(see John Marrin QC, "Concurrent Delay,"
paper given to the Society of Construction Law Hong Kong (18
March 2003)):
Apportionment—allocation of the time
and money effects of the delay to project completion based on
the relative causative potency or significance of the competing
causes of delay;
The American Approach—the contractor
is granted an extension of time relieving it of liability for
liquidated damages but does not recover delay-related loss and
damage because of its own culpable or inexcusable delay,
i.e., a "zero sum" outcome;
"But For" Test—a simplistic
argument usually raised by contractors. It arises out of
principles of causation in tort cases, the effect of which is
to ignore the contractor's delays and assert that "but
for" the owner-caused delay, the contract completion would
not have overrun;
The Dominant Cause Approach—using
principles of causation under contract law by choosing one
delay event over another according to which is the dominant
cause of the delay to completion of the project, i.e.,
only one delay event is determined to be the cause of the
overrun to the exclusion of all other concurrent delays.
The City Inn Appeal
The recent Scottish appeal decision of City Inn Limited
v Shepherd Construction Limited (Outer House, Court of
Sessions, 30 November 2007) goes the extra yard and deals with
the issue of concurrent delays, in particular the principles to
be adopted when measuring extension of time where there are
concurrent delays. Overall, the decision is based on common
sense and should be welcomed by the engineering and
construction industry. Not surprisingly, the case makes it
clear that the answers to the questions raised by concurrent
delays lie in the terms of the extension-of-time mechanism
under the contract. According to the court, and in the context
of the contract before it, concurrent delays should be dealt
with by apportioning responsibility for the delay to completion
of the project where the extension-of-time mechanism provides
that the quantification of the extensions must be based on what
is fair and reasonable. The court also held that the principle
of apportionment should be applied when quantifying
prolongation costs in circumstances where there are concurrent
delays.
The following commentary analyses the court's decision,
in particular the meaning and practical consequences of the
apportionment method to deal with concurrent delays.
The Facts
City Inn Limited ("Employer") engaged Shepherd
Construction Limited ("Contractor") in October 1997
to construct a hotel in Bristol, England. The contract was an
amended JCT Standard Form of Building Contract (Private Edition
with Quantities)(1980 edition) ("Contract"). The date
of possession under the Contract was January 26, 1998, and the
contractual completion date was January 25, 1999. Liquidated
and ascertained damages were payable at the rate of
£30,000 per week for the period between the contractual
completion date and the achievement of practical completion.
The initial architect appointed by the Employer (i.e.,
the certifying party nominated in the Contact) was a firm
called RMJM. This firm also acted as the structural,
mechanical, and electrical engineer. However, RMJM was
dismissed on December 2, 1998, and replaced by Keppie
Architects ("Architect"). Also, the firm of Blyth
& Blyth was appointed to replace RMJM as structural,
mechanical, and electrical engineers.
The Architect issued a certificate of practical completion
on April 27, 1999, certifying that practical completion was
achieved on March 29, 1999. In fact, the Employer took partial
possession of the works on March 29, 1999, and took possession
of the remaining parts on April 13 and 30, 1999. On June 9,
1999, the Architect issued a certificate extending the
contractual date for completion from January 25, 1999, to
February 22, 1999. On the same date, the Architect issued a
certificate of noncompletion certifying that the Contractor
failed to complete the works by the extended contractual
completion date. Consequently, the Contractor was awarded four
weeks' extension of time (i.e., January 25, 1999,
to February 22, 1999), but the Employer was, according to the
Architect's certificates, entitled to deduct liquidated and
ascertained damages of £30,000 per week for the period of
delay of five weeks between February 22, 1999 (the extended
contract date for completion certified by the Architect) and
March 29, 1999 (the certified date of practical completion).
The Employer then proceeded to deduct the sum of £150,000
for liquidated and ascertained damages for the five weeks of
delay.
Disputes subsequently arose between the Employer and the
Contractor, which were referred to statutory nonbinding
adjudication. The adjudicator held that the Contractor was
entitled to a further five weeks' extension of time
(i.e., a total of nine weeks) and directed the
Employer to repay the sum of £150,000. The Employer
commenced proceedings before the Scottish courts seeking a
declaration in relation to its entitlement to withhold the sum
of £150,000. The court at first instance found in favor
of the Contractor and declared that the contract completion
date should be extended by a further five weeks to March 29,
1999, and ordered that that Employer repay the withheld sum
(see City Inn Limited v Shepherd Construction
Limited 2002 SLT 781). The Employer appealed the first
instance decision to the Scottish Outer House, Court of
Sessions, which was heard and decided by Lord Drummond
Young.
Parties' Respective Positions
The Contractor's position was that it was entitled to an
extension of time of 11 weeks from January 25, 1999, to April
14, 1999, despite practical completion having been certified as
being achieved two weeks earlier on March 29, 1999. The
Contractor asserted that the 11-week delay for which it was
entitled to extensions of time was caused by a number of late
instructions by the Architect ("Relevant Events").
Some of these delay events were concurrent with each other.
In addition, the Contractor claimed £27,069 for direct
loss and expense (i.e., prolongation costs) incurred
as a result of the Architect's instructions and the
resultant alleged 11-week delay.
The Employer argued that the Contractor was not entitled to
the extension of time sought on the following bases:
The Contractor failed to comply with the notice
requirements under the Contract. (The Judge upheld the
decision at first instance and concluded that the notice
provisions relied on by the Employer were not applicable to
