Contract Practice Flashcards
What is a contract?
A legally binding promise by one party to fulfil obligations to another party in return for consideration.
A basic contract should comprise: Offer, Acceptance, Consideration, and Intention to Create Legal Relations
Please define ‘express terms’
The terms which are expressly agreed between the parties. Ideally, they will be written down but where the contract is agreed verbally, they will be the terms discussed and agreed between the parties
Please define ‘implied terms’
A contractual term that has not been expressly agreed by the parties but has been implied into the contract either by common law or by statute
What is tort?
A civil wrong that causes a claimant to suffer loss or harm, resulting in legal liability to damages
How do statutory provisions and contract provisions differ?
Statutory provisions are set out by law and must be complied with
Contract provisions relate to the contract in question and only apply to the specific project
What is your opinion of oral contracts?
Whilst they are legally binding, the difficulty lies in proving the specific terms and conditions of the agreement. A written contract is always preferred
What is a breach of contract?
When one party to a binding agreement fails to deliver according to the terms of the agreement. A breach of contract can happen in both written and oral contracts
What is the Local Democracy, Economic Development and Construction Act 2009?
The Act amended the Housing Grants Construction and Regeneration Act 1996
The Act changed the way construction contracts are entered into and introduced an amended regime for payment and adjudication
What are the key provisions under the LDEDCA 2009?
Contracts - Act repeals the requirement for construction contracts to be in writing
Payment - Construction contracts must have an adequate mechanism for payments
Payment notices - Must specify the sum due at the due date and the basis on which it was calculated
Payment notices - Payee is entitled to a default payment notice if not received
Suspension of performance - Following non payment and a default notice, the payee can suspend
What is a letter of intent?
Used to describe a letter from an employer to a contractor indicating the employer’s intention to enter into a formal written contract for the works described.
The letter of intent typically asks the contractor to begin those works before the formal contract is executed
What info is usually included within a letter of intent?
Description of the works
Contract sum (if agreed)
Date for possession
Date for completion
Insurance provisions required
Method of payment
Expiration date of the letter
Employer’s right not to award the main contract for whatever reason
ADR method for dispute resolution
What are the advantages of a letter of intent?
Allows work to commence before the main contract is agreed and signed
What are the disadvantages of a letter of intent?
May lead to complacency and disincentivise both parties from signing the main contract
Usually less robust than a main contract
Employer’s negotiation strength usually reduced
Who issues a letter of intent?
The employer
In what circumstances might a letter of intent be used?
Where the employer needs to commence work before a certain date
Starting construction work might trigger external funding
Due to the long lead-in of materials
Who usually signs the letter of intent?
Both the employer and contractor
What would you say if the client asked you to draft a letter of intent?
It is a legally binding agreement like a contract, therefore the document should be prepared by a legal professional
What are the different types of letters of intent?
Comfort letter - Expresses a parties intention to act in a particular way at some point
Instruction to proceed with consent to spend - Allows work to proceed up to a certain value
Recognition of contract - Usually marks the completion of negotiations
Are you aware of any case law regarding letters of intent?
Ampleforth Abbey Trust v Turner & Townsend - Contractor never signed the building contract and the entire works (new school accommodation) was procured under letters of intent. This meant the Trust was unable to claim LAD’s under the building contract. Judge found that T&T had been negligent.
What is a parent company guarantee?
A form of security that may be required by clients to protect them in the event of default on a contract by a contractor that is controlled by a parent company. Typically, such a default might be caused by insolvency of the contractor.
In what circumstances might a PCG be required?
Where a small contractor is part of a large financially stable group of companies. The parent company will be required to remedy the breach of contract.
Are there any Acts that govern third party rights?
Contracts (Rights of Third Parties) Act 1999
What is the overarching purpose of this Act?
Allows third party to enforce terms of a contract they are not party to, but that benefit them in some way.
It gives parties access to various remedies if those contract terms are breached
What are the advantages of third party rights?
Time and cost - since no separate document (collateral warranty) is being entered into
Certainty - Limited room to revisit the wording
Subcontractors - Can be extended to subcontractors, so that an employer can confer the rights
What are the disadvantages of third party rights?
Lack of flexibility - limited room for negotiation
Need for careful drafting - enforcement provisions must be clear
Why might third-party rights be used instead of collateral warranties?
To save on time and cost
What is a collateral warranty?
A formal contractual agreement which runs alongside another contractual agreement
Its purpose is to create a contractual relationship between two parties where one would not otherwise exist
Who might want a collateral warranty?
The employer may want a collateral warranty with key subcontractors or suppliers, to provide a redress for defective workmanship
Difference between a bond and a collateral warranty?
A bond is a financial commitment backed up by a third party, whereas a collateral warranty passes on contractual obligations
Bonds are contained within the contract
Collateral warranties are a side agreement to the contract
Are there alternatives to collateral warranties?
An alternate method to confer such rights is provided by the Contracts (Rights of Third Parties) Act 1999 which allows third parties to obtain benefits from contracts entered into by others.
What are the three ways that benefits can be transferred under a building contract?
Collateral warranties
Third party rights
Assignment
Are you aware of any case law relating to Collateral Warranties?
Parkwood Leisure V Laing O’Rourke
Abbey Healthcare (Mill Hill) Ltd v Simply Construct (overturned)
There is a high probability that collateral warranties will be needed under a D&B contract. Why is this?
The design team sit below the contractor on a D&B contract; therefore, the employer will need to retain a contractual link with the design team (using a collateral warranty).
What is assignment?
The process whereby the benefit of a contract is transferred from one party to another but the burden of the contract remains with the original party to the contract.
What are some of the typical clauses of assignment?
It is standard to allow assignment of rights twice without consent
The assignment should be notified in writing
What is a bond?
An arrangement where a contractual duty owed by one party to another is backed up by a third party
Can you list five bonds that might be used on a construction project?
Performance Bond
Retention Bond
Advanced Payment Bond
Off Site Materials Bond
Tender Bond
What is a Performance Bond?
A form of security provided by a contractor to a developer or employer
It consists of an undertaking by a bank or insurance company to make a payment to the employer in circumstances where the contractor has defaulted under the contract
When might the employer want a Performance Bond?
If there is concern over the contractor’s financial standing
If the contractor is new or unapproved
The economy might be heading into recession
The employer simply wants to protect their commercial exposure
What is the difference between on-demand and conditional Performance Bonds?
On demand bonds are immediately available without any preconditions being met
Conditional bonds require the employer to provide evidence the contractor has not performed their obligations and that they have suffered a consequent loss
What is the typical value of a Performance Bond?
Typically 10% of the contract sum
What is the typical cost of a Performance Bond?
The cost largely depends on the financial stability of the contractor and the number of previous claims
What is the risk of not having a Performance Bond?
In the event a contractor goes into insolvency and there is no bond in place, the employer will be liable to pay all costs to deal with the insolvency. Costs include sourcing a new contractor to complete the works and any premium that will attract
The employer will not be liable to pursue the contractor as the company will be in the process of liquidation
Are there any alternatives to a Performance Bond?
If the contractor is part of a group of companies, the employer can consider a Parent Company Guarantee
If the smaller company breaches the contract, the parent company is obliged to step in and remedy the breach
What is a tender bond?
Requested by the employer when inviting contractors to tender for a contract
A tender bond provides security against the risk of the successful bidder failing to enter the contract
It should help prevent idle tendering
What is an off-site materials bond?
Covers an employer against the risk of paying the contractor for materials being manufactured off site.
If the contractor becomes insolvent, the employer can claim on the bond for goods paid for (in the event they are not delivered to site)
What is a retention bond?
A type of performance bond - rather than withholding retention, the bond agreement confirms the surety will pay the employer up to the full retention amount if the contractor fails to perform the obligations or remedy defects immediately after contract completion
What are the disadvantages of a retention bond?
The employer will have to pay the premium of taking out a bond
May reduce the contractors incentive to complete the work promptly to the desired standard
Why might a retention bond be used?
In difficult market conditions to aid the contractors cash flow
What is an advanced payment bond?
Covers an employer against the risk of paying a contractor in advance for something which may not materialise (due to insolvency for example).
What are antiquities?
Historical artifacts, pottery and coins
Bones or fossils
Something of historical interest or values
Archaeology
What should the contractor do if they discover such objects?
Cease work and seek advice prior to proceeding
Take the necessary measures to preserve in the existing location and condition
Inform the contract administrator or project manager of the discovery
When objects of interest are discovered, who is liable for the delay and expense?
This depends on how the risk is allocated within the contract
What are defects?
Defects are aspects of the works that are not in accordance with the contract
What are patent defects?
Those which can be discovered by reasonable inspection (broken windows)
What are latent defects?
Those which cannot be discovered by reasonable inspection (settlement issues)
Why is the defect rectification period usually 12 months?
12 months will allow the building to go through all seasons of the year, therefore, most defects will become apparent during this time period
What is novation?
The process whereby the benefit and burden of a contract is transferred from one party to another - this is common under D&B contracts where the design consultants are initially contracted to the client, before being novated to the contractor.
Are novation agreements required under traditionally procured projects?
Not usually, because the designers are retained by the employer
What are the advantages of novation?
Reduced learning curve - between design team and contractor
Reduced contractual risk for the employer
What are some of the disadvantages of novation?
Following the novation of consultants, the employer will typically require collateral warranties
Potential for conflict of interest, particularly relating to the services yet to be performed
What is retention?
A percentage of the sums certified for payment under the construction contract, typically 3-5%, which are held by the employer during the construction phase
Are you aware of any guidance issued by the RICS associated with Retention?
Retention - 1st Edition
What is the purpose of retention?
To provide the client with some security the contractor will return to correct any defects which arise during the Rectification Period.
What can the employer use retention monies for?
To fund the payment of others to correct the defects (contract needs to be checked beforehand)
How is retention released to the contractor?
Typically over two stages: 50% upon practical completion, 50% upon Certificate of Making Good.
Who typically benefits from the interest accruing on retention money?
Usually the employer
Are there any alternatives to holding retention?
It is possible to procure a retention bond to cover the retention that would otherwise have been deducted
What is professional negligence?
When a professional fails to perform their responsibilities to the required standard or breaches a duty of care. This poor conduct subsequently results in financial loss, physical damage or injury to their client.
How can the employer recover a loss if the consultant or contractor is professionally negligent?
Make a claim on their professional indemnity insurance (PII)
What is professional indemnity insurance?
Insurance which provides cover against the cost of claims for loss or damage associated with professional negligence or advice provided by a business or consultant.
What is product liability insurance?
Manufacturers or suppliers of products are at risk of claims being made against them for damages if defects in those products result in damage - product liability insurance protects the policyholder against such claims.
What is public liability insurance?
Provides protection against liabilities for injury to third parties or their property.
For example, a member of the public could make a claim if a fallen brick damaged their car.
What is employer liability insurance?
Can pay the compensation amount and legal costs if an employee claims compensation for a work-related illness or injury
What is Contractor Design Portion?
Typically used on traditionally procured projects, design responsibility for specific elements of the building is transferred to the contractor.
What is the difference between traditional procurement with CDP and D&B?
Traditional procurement with CDP - design responsibility lies with the employer except for certain elements.
Design & build - all responsibility for the design rests with the contractor
How are CDP elements executed?
A performance specification is provided at tender stage, the contractor then provides design proposals in response. These proposals are then reviewed by the design team and either accepted, commented upon, or rejected
Can you list typical CDP elements the employer may wish to transfer?
Steelwork connections
Cladding
Roofing
Temporary works
MEP elements
What are ‘named subcontractors’?
The employer provides a list of named subcontractors that are pre-approved
The contractor selects one from the list through the tendering process
Once appointed by the subcontractor, they then become a domestic subcontractor
What are ‘domestic subcontractors’?
Chosen by the contractor to execute a package of work
Neither the employer nor employer’s consultants influence the appointment or conditons
What are the advantages of naming subcontractors?
Provides the employer with more control to the selection of a subcontractor by the contractor, whilst still leaving them with the element of choice and the responsibility of monitoring and managing their performance
Contractor can form new valued supply chain relationships
What are ‘nominated subcontractors’?
A nominated subcontractor is selected by the employer to carry out an element of the work
Their selection is usually imposed on the contractor
What are the disadvantages of ‘nominated subcontractors’?
The contractor and subcontractor may have conflicting procedures (ethics / attitudes etc)
Can lead to disputes over liability in the event of non-performance of the subcontractor
What are the advantages of ‘nominated subcontractors’?
Given they are recommended by the employer, their work should be of high quality which is acceptable to the employer
Are you aware of any guidance issued by RICS associated with subcontracting?
Subcontracting, 1st edition.
What is insolvency?
The inability to pay debts
What can be done at tender stage to identify the risk of contractor insolvency?
Thorough check of financial accounts for stability, via Companies House
Check for front loading within the tender submission
Using credit agencies (Dun & Bradsheet reports)
Previous references from consultants and employers
Request a bond or parent company guarantee
What is termination?
When a contract is terminated, the parties are no longer obliged to perform their obligations under the contract
Can the contractor suspend work for non-payment?
Yes, under the Construction Act - if the notified sum is not paid by the final date for payment, the contractor must give at least 7 days notice, before suspending works.
What are delay damages / LAD’s?
A genuine pre-estimate of loss suffered by the employer because of late completion of the works. The damages are inserted into the contract prior to the signing by the contracting parties.
LD’s should not be a penalty / they provide a quick remedy without having to prove actual loss / contractor knows their liability
What sort of expenses / costs can the employer include in the damage calculation?
Loss of rent or other income
Additional professional fees
Expected costs incurred by other parties
Capital salaries
Legal costs
It should not be construed as a penalty, and must be a genuine pre-estimate of loss
How would you react if the client tells you the damages are £100,000 per week?
Exercise due diligence - check that they do believe £100,000 per week is a genuine pre estimate of likely loss
If there is a concern, explain the damages might be construed to be a penalty (which is not enforceable)
Under JCT contracts, what contractual documents should be in place before damages are deducted?
A non-completion certificate
Formal notification of the employers intention to levy liquidated damages
A pay-less notice
What is a LD holiday or LD free period?
Essentially a grace period in which the contractor has no commercial liability for delay
What is the implication of inserting ‘nil’ against the damage clause?
This effectively means there are no liquidated damages. This action may prevent the employer pursuing unliquidated damages.
What is the implication of leaving the damage clause blank?
If the clause is left blank, the employer can pursue unliquidated damages from the contractor.
What is the difference between liquidated damages and unliquidated damages?
Liquidated damages are contract stipulated charges due on breach of contract (usually delay)
Unliquidated damages are granted by the courts based on an assessment of loss following a breach
If the Completion Date is adjusted, what effect does this have on delay damages?
Damages will be levied from the revised Completion Date
Can the employer levy liquidated damages if they do not incur the loss identified in the initial calculation?
Yes - provided the damages are not deemed to be a penalty, and the original calculation was a genuine pre estimate of the loss
What is a pre-construction services agreement?
A contract between the employer and contractor for pre-construction services
The PCSA documents the services the contractor is due to perform before signing the building contract
When might a PCSA be used?
In a two-stage tender approach to facilitate early contractor involvement
How can a PCSA benefit the project?
Early involvement of the contractor should improve the buildability and cost certainty of design
What should be considered when drafting the PCSA?
Arrangements do not commit the employer to entering into the building contract
The scope of services needs to be clear and unambiguous
The usual programme and delay damage clauses are carefully drafted by the legal team
What are the main forms of building contracts?
JCT (Joint Contracts Tribunal)
NEC (New Engineering Contract)
FIDIC (International Federation of Consulting Engineers)
Bespoke contracts
What are some of the considerations when selecting the appropriate construction contract?
Nature of the client
Priorities - time, cost, quality, risk allocation
Procurement choice
Value of work
Type of work
Public or private employer
Complexity of work
Size and location of work
What is a bespoke contract?
Contracts that are tailored to fit the specific requirements of a project
Often used when standard forms are not suitable
What are the advantages of standard forms over bespoke contracts?
Written by legal experts
Rights and obligations of each party are clearly set out
Parties should be familiar with provisions of form, resulting in greater consistency of application
What are the disadvantages of bespoke contracts?
Lack of familiarity as they are rarely used
Expensive to draft (legal fees)
Provisions untested in court
When would a bespoke form be appropriate?
When amending a standard contract will not do, the most efficient means of achieving a client’s requirements might be to create a bespoke contract
Have you amended a standard contract? Can you explain how you did this?
I do not have the necessary legal training, so do not amend contracts.
All amendments should be drafted by the legal team.
What are some of the risks associated with amending a standard contract
Amendments can spoil the equitable balance of risk allocation
Can create legal uncertainty
Can attract a cost premium to tenderers
Amendments must be reasonable and comply with legislation

What is the key thing to remember when assessing loss and expense claims?
It should be the actual loss incurred
The rates and prices in the pricing schedule should not be used
Refer to RICS Guidance Note - Ascertaining loss and expense - 1st edition.
What are the common heads of claim in loss and expense?
Prolongation (extra preliminaries)
Disruption (unproductive time)
Increases in labour and material costs
What are prolongation costs?
A type of financial claim made by contractors due to project delays - capturing the costs of time related resources such as staff, accommodation and plant.
What is partial possession?

What are the key points of partial possession?
Not agreed in advance
Completion is deemed to occur for that section
Voluntary agreement between employer and contractor

What are the benefits of sectional completion over partial possession?
Sectional completion leaves less to chance, because the parties have pre-agreed the practical implications
What are the main options for insuring the works under a JCT contract?
Option A - The contractor takes out and maintains joint names all risk insurance of the works for new buildings
Option B - The employer takes out and maintains joint names all risk insurance of the works for new buildings
Option C - The only option referring to refurbishment and alterations to existing structures. Where the employer takes out and maintains a joint name all risk insurance policy for the works.
What is a joint names insurance policy?

What is contractors ‘all risk’ insurance?
Policy pays for the repair or replacement of the insured works following damage caused by an insured event.
What are specified perils?
Significant events that would cause very significant damage to the works, including:
Flooding / fire / explosions / earthquakes
What is subrogation?

Option W2 - When adjudication is the method and the HGCRA does apply
Option W3 - Dispute Avoidance Board
What problems can arise when drafting Z clauses into the contract?
Poorly drafted Z clauses can be problematic if they are not drafted by experienced professionals, as they may not work with the core clauses.
What are the different types of float on an NEC4 ECC programme?
Total float
Time risk allowances
Terminal float
What is total float?
The time an activity can be delayed without delaying planned completion.
Owned by the Client & Contractor - depending on whoever gets there first.

How can the planned completion date be changed?
Anything can change it
Which of the NEC ECC contracts are D&B?
The NEC ECC contract is suitable whether the contractor has no design responsibility, part design responsibility, or entire design responsibility.
This will be set out in the scope.
What are compensation events?
