Analysis of Claims Based on Provisions in 4th Edition of
FIDIC Contracts

Dr C.S.Suryawanshi, Sr Techno Legal Consultant Mumbai

Claims and Counter Claims in all Construction Contracts play an important role in the Contractual

relation ship between employer and contractor. Generally Claim is reckoned in practice as “an

assertion for additional monies due to a party or for extension of time for completion. This

interpretation is construed from a wording of the Contractual provision. Arbitrations on the claim

matters are on its rise. Engineer arbitrators interpret the provisions of Standard Contract Forms in

the traditional way- & legal personnel interpret in the legal sense.

This paper discusses some of the principles as regards basis of claims and clarifies the provisions

pertaining to “Variations “as embodied in the present day Standard Contract Forms, of FIDIC.

Introduction

Typical sources of disputes and claims are worth noting, before we consider its Analysis.

Theoretically, any clause in the contract can become the basis of a claim. Indeed, it is a wonder

that contracts have not become much simpler on this account alone. However, we are governed by

explicit law, expressed by a profession whose major product is more words! Generally, disputes

may be identified as arising from any one of the following main groups:

Changed conditions. Conditions different from that represented by the contract

documents, or known at the time of bidding for the work, such as different soil conditions, or

unknown obstructions etc.

1.

Additional work. Disputes over the pricing and timing of additional work required, or even

whether a piece of identified work is in the contract or not. Beware particularly of omissions

in the design documents, requiring changes to make a system work, especially if they

appear in a subtle way through the shop-drawing review and approval process. This is

always very embarrassing for the designers, who would like to see them incorporated for

free! Beware also of changes requested by the users (as distinct from the owners) of the

project.

2.

Delays. These refer to delays strictly beyond the contractor’s control. They may be caused

by the owner directly, or by one of his agents. A prime example is failure to give access to

the site of the work in a timely way. Or equipment promised by the owner is not delivered

on time. More frequently, working drawings are not provided in time to suit the work, or

shop drawings are not reviewed in a timely manner.

3.

Contract time. Disputes over a contractor’s request for time extension on account of

changed conditions, required changes to the contract, or owner caused delays. Disputes may

also arise over instructions to accelerate the work. Such instructions may not necessarily be

explicit. For example, instructions to incorporate additional work without a corresponding

time extension especially if the work is on the critical path, is tantamount to an instruction to

accelerate in order to meet the contract completion date.

4.

The construction contract is unique in that it seeks to provide for a specific remedy in the event of

any breach of the terms and conditions within its framework and/or for a contractual entitlement in

respect of specified events. Therefore, it is essential that the parties and those who represent them

fully comprehend the terms of the contract and the remedies available to them under it.

Claim

Curiously, for such a fundamental aspect of the contract, no express definition appears in the

typical standard form of construction contract and it is rare to find a definition of ‘a claim’ in

reference texts or authorities on construction contracts. A claim is defined in The Oxford

Companion to Law as a general term for” the assertion of a right to money, property, or to a

remedy.” Strictly speaking then, whenever for example the contractor applies for his monthly

interim payment for the original scope of the works, or whenever for example the employer writes

to the contractor requiring him to remedy defective work, it would be a claim under this definition.

In construction contracts, in traditional way, a claim is generally taken in practice to be an

assertion for additional monies due to a party or for extension of the Time for Completion. This

interpretation of ‘a claim’ is borne out by the wording of the contractual provisions relating to

claims. For example, clause 44 of the Fourth Edition of the Red Book provides for an entitlement to

‘an extension of the Time for Completion of the Works or any Section or part thereof (emphasis

added), albeit that the word ‘claim’ appears nowhere in this clause; and sub-clause 53.1 includes

the words ‘..if the Contractor intends to claim any additional payment. . .’ (emphasis added).

However, nowhere is there a reference to an assertion for a declaration, although such a claim is

frequently made.

Then it is clear that the form of contract seems to ignore claims arising from anything other than

the assertion for an entitlement to payment or time extension.

Counter Claim

A counterclaim is defined as an assertion made by a respondent party which can conveniently be

examined and disposed of in an action originally initiated by the claimant party. It is not

necessarily a defence, but a substantive claim against the claimant which could have grounded an

independent action. The concept of convenience referred to here signifies that the background of

the counterclaim is similar to that of the claim and results from the same set of facts and events.

For instance, a party might be precluded from bringing a counterclaim in arbitration either because

the claim is not subject to arbitration (i.e. arising from another contract or a different event) or by

virtue of the conditions prescribed by the contract initiating an entitlement to claim. Furthermore,

in the sense that the word is used, it would not include a defence where that defence does not

itself give rise to an actionable claim against the claimant.

Broad Basis of the Claims

In number of cases, Claims as we see to day arise from:

documentationi.

in connection with execution of the workii.

concerning payment provisionsiii.

concerning timeiv.

default, determination etcv.

Compound claimsvi.

Essentially, other than claims under statutory law, claims in construction contracts may be based

on legal concepts and non-legal concept. Therefore, if a claim is required to be categorised, and it

is suggested that it should be, the categorisation could be done in accordance with the following

five categories:

A claim under the contract:

The first category relates to a claim under the contract between the parties based on the

grounds that should a certain event occur, then a claimant would be entitled to a remedy

that is specified under a particular provision of the contract, subject to the effect of the

applicable law. Such an event may be one of two types.

First, it may be a specified event under the contract, which might or might not occur,

where in certain defined circumstances the employer or the contractor is entitled to

claim a designated remedy. For example, the contractor is entitled to claim an

additional payment under the Red Book for tests in accordance with the provisions of

sub-clause 36.4.

i.

Secondly, the specified event may be a breach of a particular provision in the contract

entitling a claimant to a designated remedy if the terms of such provision are not, or

are only partially, complied with. If the claim is successful, the particular provision in

the contract would apply and the remedy could be in the form of a payment of a sum

of money, or an extension of time, or some other benefit, or a combination of all

three.

ii.

For example, it is stipulated in the Red Book that failure by the’ contractor to complete the

works on a specified date would entitle the employer to deduct liquidated damages at a

specified rate per day or week. In this connection, the provisions of the applicable law must

be taken into consideration, for instance whether such damages are in effect a penalty, and

if so, whether or not this can be treated as a valid claim.

a.

A claim arising out of or in connection with the contract:

The second category relates to a claim arising not under, but out of or in connection with,

the contract, where the remedy is not designated in the contract and the claimant needs to

invoke a provision of the applicable law to obtain a remedy. Therefore, if the claim is valid,

the remedy lies under the provisions of the applicable law of the contract, for example a

claim for a breach of contract. Under English law, the remedy for a breach of contract would

be under the principles governing damages, including those laid down in the Hadley v.

Baxendale. The remedy in this case may extend to consequential damages, if foreseeable at

the time of contracting, unless excluded by the contract. Furthermore, if the breach is of a

serious nature, the aggrieved party might be entitled to cancel the contract and, if the

breach amounts to the communication of an intention not to abide by the terms of the

contract, such conduct could amount to a repudiation which would be open to acceptance by

the innocent party.

Furthermore, if the employer terminates the contract, the contractor might have a lien over

the works, depending on the terms of the contract, which would act as security for the

payment of any money owed to it arising from the work performed pursuant to the contract.

Another example of a claim arising in connection with the contract, but not under it, is where

one of the parties has misrepresented certain important facts in negotiations leading to the

formation of the contract. In such case, the other party may use this as a basis for

cancelling the contract or for claiming damages. However, the terms of the contract may

exclude the right to cancel for a serious breach or misrepresentation. If, however, such

misrepresentation constitutes fraud, the party making the representation would not be

allowed to rely upon such an exemption clause.

b.

A claim under the principles of the applicable law:

The third category relates to a claim arising under the application of the principles of the

applicable law, either by the parties to the contract or against third parties. This could lead

to a claim under the law of tort, or delict as it is referred to in some jurisdictions.

The law applicable to a claim in tort/delict is not necessarily the same as the governing law

of the contract. If the claim is successful, the remedy would typically be an award of general

damages, the amount being dependent upon the particular circumstances of the case.

Depending on the applicable law, the parties may have concurrent claims arising from the

contract and from tort/delict. Although the result will often be the same, the measurement

of the loss is, in principle, different. Complicated questions arise between contracting parties

as to the implementation of terms limiting the aggrieved party’s entitlement to a claim

brought in tort/delict. This might even apply to rights of action to persons who are not privy

to the contract.

For example, a party might wish to bring a claim in tort/delict rather than in contract

because of time limitations; where there is an arbitration clause imposed by a contract;

where there is an insurance policy covering particular claims; or where notice provisions

under the contract affect the aggrieved party’s entitlement to claim.

A claim arising out of the principle of quantum meruit:

The fourth category comprises claims where no contract exists between the parties, or if one

existed, it is deemed to be void. It is based on the principle that an individual has the right

to be paid a reasonable remuneration for work done. This is referred to in some legal

systems as quantum meruit or ‘as much as one has earned’ and has been often equated to a

claim for undue enrichment. The principles of quantum meruit have also been applied to

cases where there is a contract in existence but the price is not stipulated; instead the

contract expressly provide that the amount to be paid will be based on a reasonable sum or

the price will be agreed from time to time. In Hudson’s Building and Engineering Contracts,

it is stated:

‘. . . quantum meruit is frequently employed . . . where a true contractual situation exists, in

the sense of a request to do work accompanied by an intention to pay for it, and so

supported by consideration, but where the price may not have been fixed at all, or with

sufficient precision, by the contract, so that a promise to pay a reasonable price requires to

be implied to give practical effect to the parties’ intentions.

The case of Constable Hart & Co. Ltd v. Peter Lind & Co. Ltd is one example where the court

applied this principle. If the claim is successful, payment is assessed on the basis of a

reasonable recompense of the cost of the work carried out by the contractor and may,

although not necessarily, depending on the principles of the applicable law, include an

element of overhead and profit.

Generally, the remedy for all the four categories of claims set out above would be sought

through an action in arbitration or litigation unless the claim is settled amicably. Such action

would usually necessitate the employment of lawyers and the outlay of large expenditure

d.

A claim for ex gratia payment:

Finally there is the claim for an ex gratia payment (meaning out of kindness). Although

claims for ex gratia payments are not claims which arise by virtue of a contractual

entitlement, they are sometimes entertained by employers and engineers as a matter of

expedience to avoid arbitration or litigation and, indeed, to maintain the goodwill necessary

to complete the project successfully. There is no applicable legal basis for such payments,

but rather some commercial sense or benefit in reaching a settlement between the parties

without acceptance of liability.

e.

Only the first two categories of claim are considered here, i.e. those which are made under the

contract or which arise out of the contract, as the other categories of claim are beyond the

provisions of the Red Book.

An analysis of “Variation” Claims

Variation Claims under the contract are presented, in the first place, to the engineer who should

determine, impartially, the entitlement of the claimant in principle and in quantum. Such

determination, if unacceptable to either the employer or the contractor, may be ‘opened up,

reviewed or revised as provided in Clause 67’ (Settlement of Disputes).

(See sub- clause 2.6 of the Red Book).

A claim under the contract and based on its provisions

As previously stated, the Red Book regulates the rights and obligations of the parties to the

contract. Its provisions specify what should be done by the two parties or their agents and servants

and the consequence if what ought to be done is either not done, or if done, is not done within the

time specified.

Claims will very often arise in a traditional construction contract because it is perhaps the only

contract where the price of the end result is defined before the process of ‘production’ even starts.

Accordingly, in the competitive atmosphere of tendering which accompanies such a contract, little

or no margins are left for future unknowns in a long and complex period of construction.

Furthermore, as the rates and prices have to be based on certain assumptions which are, in turn,

based on the provisions of the Conditions of Contract, any change between what was assumed and

what actually happens may form a seed for a claim.

As already stated, claims under this category may be divided into:

claims as a result of certain anticipated and specified events and for which a remedy is

designated in the contract; and

a.

claims as a result of an event where a certain term of the contract is breached and for which

a remedy is designated in the contract.

Meaning of the term “Access to Site”

“Access to Site” may have a number of meanings in a construction contract. It may refer to the

means and availability of the approach to the Site area, whether by land, sea or air. It may also

mean the ability to occupy the site area. The second sense is usually referred to as “possession of

the site”, although terms such as “access to site” and “use of site” are also used. The first meaning

of “Access to Site” is examined below.

Access to the site in which the works are being constructed is necessary to allow transport and

delivery of materials, plant and equipment as well as to allow services and the workforce to reach

the site. In order to be effective the access must be suitable for the type of transport required and

must be available to the contractor at the appropriate time. Even if access is physically available

local permissions and custom clearances may be necessary to allow legal use of access.

Apportionment of Responsibility

The extent of any responsibility for providing the required access across adjacent property and

buildings, obtaining the necessary permissions and the apportionment of risk for events which

prevent the required access, will depend upon the terms of the contract. Generally, if it is

necessary for one party to cooperate in order for the other to carry out the work, then a term will

be implied (in the absence of express terms) requiring that party to do all that is necessary for him

to do to complete the works-London Borough of Merton v Leach (1988) 32BLR51. The extent of the

obligation to provide access and obtain permissions will depend upon the type of work involved, the

extent of possession and/or control of adjacent areas by that party and all the circumstances. Even

if a term is implied that such physical access is to be provided by one party, the term may not

extend to requiring that party to take responsibility for the adequacy of the access for the transport

of plant and equipment for the works.

General Case Law

Two decisions of the courts one Canadian and one English, demonstrate the principles involved in

apportioning responsibility for providing access to site.

In the Canadian case of Penvidic Contracting Co Ltd v International Nickel Co. of Canada Ltd

[1975]53 DLR 748 the contract involved the laying of track and top ballasting on a railroad.

Penvidic was the contractor and work was constantly delayed by the failure of other contractors to

properly grade and sub-ballast the right of way in front of its machinery. In addition the

International Nickel Co failed to obtain the necessary way leaves and permissions to cross various

hydro lines and highways. It was held that the extent of possession or access provided by an

Employer would vary with the nature of the work and the circumstances. In the case of a new

project the main contractor would normally be entitled to exclusive possession of the entire site in

the absence of express terms to the contrary. A term would normally be implied that the site would

be handed over within a reasonable time and, in most cases, with a sufficient uninterrupted

possession to allow the contractor to carry out his obligations by the method of his choice. It was

held that International Nickel Co had failed to do so and that this was a breach of contract entitling

Penvidic to damages.

In LRE Engineering Services Ltd v Otto Simon Carves Ltd [1981] 24BLR131 Simon Carves was the

contractor for building works at steelworks at Port Talbot. LRE were subcontractors and had

completed a very substantial proportion of the works when a steel strike broke out. The activities

of pickets at the site prevented LRE completing the work until some considerable time later,

causing them to incur considerable additional costs. LRE maintained that Simon Carves was in

breach of contract in that it had an absolute obligation to see that there was available entry to the

site at all times. This was not accepted. It was held instead that the term “access” had more than

one meaning in the relevant Clause 24. In one part of the clause it meant “physical means of

access” since that part also referred to the condition of the access. Another part of Clause 24

placed an obligation on Simon Carves to “afford access” to LRE. This meant that Simon Carves

undertook that at the relevant time there would be a physical means of access and also that LRE

would be given the opportunity to enter the site by means of that access. On this interpretation it

was held that there was no breach of contract. Simon Carves had provided LRE with the

opportunity of entering the site by the required means of access. The fact that they were prevented

from doing so was not a breach of contract.

Standard Forms

The standard forms generally expressly state the responsibilities for access to Site, in terms which

reflect the type of work envisaged and the expected use of the forms.

FIDIC 1998

The FIDIC Red, Orange and Yellow Forms 1999 place the main responsibility for access on the

Contractor and reflect the international and civil/mechanical type of works envisaged.

Clause 2.2 only requires the Employer to provide reasonable assistance, and then only at the

Contractor’s request, for the Contractor’s application for permits, licences or approvals including

clearance through customs and export of the Contractor’s Equipment when removed from Site.

Clause 4.13 makes the Contractor responsible for special and/or temporary rights of way including

those for Access to the Site.

Under Clause 4.15 it is for the Contractor to satisfy himself as to the suitability and availability of

access to the Site, and is responsible for obtaining permissions to use the route and signs. Clause

4.15 expressly provides that the Employer does not guarantee the suitability or availability of

particular access routes.

The remedy in both of these types of claim is designated in the contract and the claim may include

Variations

The nature of variations, the responsibility for them and their valuation are discussed in this

section.

Nature of variations

Although some claims can be avoided by proper planning and risk management, claims for

variations, as indeed claims in general are inevitable since it is practically impossible to foresee

every event that might occur during the construction period and to plan in advance for the

consequences of such events. If that concept is accepted, then it is necessary to incorporate into

the contract a mechanism for implementing changes which are found to be necessary or desirable

during the construction period. These changes are permitted to be made to the works but not to

the contract.

Clauses 51 and 52 in the Red Book provide for such a requirement by authorising the engineer to

vary the works or any part thereof. They also regulate the rights and obligations of the parties in

the event of such variations. The wording of sub-clause 51.1 confines this authority to make

variations to the engineer. The first sentence of sub-clause 51.2 is in fact more specific in this

respect in that the contractor is prevented from making such a variation without an instruction

from the engineer. The engineer’s authority in this respect is extremely wide extending to the

‘form, quality or quantity of the Works or any part thereof. However, in the case of additional work,

such authority is explicitly restricted in paragraph (e) of sub-clause 51.1 to ‘any kind necessary for

the completion of the Works’. Accordingly, the engineer’s authority to add further work to the

contract is restricted so that it does not include work alien to the original concept of the contract or

work which is not necessary for its completion.

An instruction is required from the engineer to the contractor to initiate a variation and such an

instruction is required to be in writing in accordance with sub-clause 2.5, or, if given orally, then it

should be confirmed in writing as provided for in that sub-clause. Some commentators have

suggested that a drawing may constitute an instruction in writing if it is issued showing a change

from previous drawings and the change may be defined as a variation. Of course, it would always

be preferable to issue the drawing accompanied by a specific communication as to the nature of

any contemplated variation. What is and what is not a variation is a major source of dispute in

many projects and a frequent issue in arbitral proceedings.

Sub-clause 51.1 also provides that the engineer may vary the works or any part thereof if for any

reason, other than it being necessary, and he finds it appropriate to:

increase or decrease the quantity of any work included in the contract but an instruction for

such variation is not required if the actual quantities of the work envisaged at the time of

tendering prove, on remeasurement, to be different from those recorded in the bill of

quantities, see sub-clause 51.2. The effect of such a variation must then be taken into

account in determining whether or not the provisions of sub-clause 52.3 apply;

a.

omit such work provided it is not to be carried out by the employer or by another contractor;b.

change the character or quality or kind of any such work;c.

change the levels, lines, position and dimensions of any part of the works;d.

execute additional work of any kind necessary for the completion of the works;e.

change any specified sequence or timing of construction of any part of the works. ~f.

Paragraph (f) of sub-clause 51.1 which is a new provision under the Fourth Edition assumes that

some specified sequence or timing of construction had already been made in the contract

documents. It adds a new dimension to the meaning of a variation from previous editions of the

Red Book in that it encompasses the timing of construction and its programme. Any change from

the specified sequence or timing stated in a programme submitted by the contractor under clause

14 and instructed by the engineer under clause 51 would therefore qualify as a variation. Such a

change may be in the form of a requirement to accelerate the work or to vary its timing.

Sub-clause 51.1 of the Red Book also provides that any variation instructed by the engineer should

not vitiate or invalidate the contract. It has been suggested that as a matter of business efficacy,

this provision must be subject to an implied limitation of reasonableness in so far as instructions

cannot stray ‘outside the Contract’. Extras, therefore, must not be of a certain value and type and

must not be instructed at a time which would render the contract inapplicable.

Responsibility for variations

The allocation of liability for the value of any variation instructed by the engineer is dependent

upon whether or not the necessity for it is due to some default of or breach of contract by the

contractor. Accordingly, any additional costs attributable to a variation necessitated by some

default of or breach of contract by the contractor are to be borne by him; see sub-clause 51.1.

Valuation of variations

Valuation of the variations referred to above is provided for under clause 52 of the Red Book which

provides the rules for such valuation. In essence, they are:

Within 14 days of the date of an instruction to vary the works in accordance with clause 51,

and before commencement of such work, a notice is required to be given either:

by the contractor to the engineer of his intention to claim extra payment or a varied

rate or price; or

i.

by the engineer to the contractor of his intention to vary a rate or price.ii.

It is clear by including this notice requirement in the provison of clause 52.2 that a valid

notice of intention to claim is a condition precedent to any additional payment. The

importance of this condition can only be evaluated in the light of the provisions of the

applicable law of the contract. Furthermore, in general terms, the treatment of this topic

under civil law jurisdictions differs significantly from that under the common law. In England,

the relevance of such notice was highlighted by the Court of Appeal in 1965 in the Tersons

case when it was held that a notice need only indicate the intention to make a claim and

identify in general terms the & additional work to which the claim will relate. It is noteworthy

that the wording of the clause in question in that case is different from that in the Fourth

Edition of “‘ the Red Book from the point of view of the period within which it had to be

served. The words of the clause in the Tersons case were: ‘as soon after the date of the

order as is practicable’, as against the period of 14 days specified in the Red Book.

a.

Such notice is not required to be given where the variation entails an instruction to omit

work.

b.

Varied work is valued in one of four different ways.

The first is where the variation is valued at the rates and prices set out in the contract if, in

the opinion of the engineer, these rates and prices are applicable to the items of varied

work. In considering the applicability of the rates and prices in the contract to the varied

work, the engineer would have to take into account the nature and amount of the varied

work in addition to, presumably, the preliminary items which may be affected, the time

when the variation is ordered, the method of its construction and its physical location

compared with the other work under the contract.

c.

The second way in which a variation may be valued is where there are no applicable rates

and prices in the contract, then the contract rates and prices are to be used as the basis for

valuation so far as may be reasonable.

d.

The third way in which a variation may be valued applies if the contract rates and prices

cannot be used as a basis for valuation; then the engineer is required to agree new suitable

rates and prices through the procedure of ‘due consultation’ with the employer and the

contractor.

Where no agreement is reached between the engineer and the contractor, then the engineer

is required to fix such rates and prices as are, in his opinion, appropriate. Having done so,

the engineer is required to notify the contractor accordingly with a copy to the employer.

Whilst no time limit is imposed on such agreement on suitable rates or prices, or any

subsequent requirement to fix such rates or prices, in case of disagreement, the engineer is

required under sub-clause 52.1 to determine provisional rates or prices for the purposes of

on-account payments in any certificate issued under clause 60.

Sub-clause 60.2 provides that ‘the Engineer shall . . . certify. . . the amount of payment to

the Contractor which he considers due. ..’. It may, therefore, be taken that whatever is

certified under the monthly payment will have to incorporate properly assessed rates and

prices for the various items of work executed and incorporated in the monthly statements of

the contractor pursuant to sub-clause 60.1 ‘to which the Contractor considers himself to be

entitled’.

Under the heading of applying new suitable rates or prices, sub-clause 52.2 provides for the

possibility of changing the rates or prices of items of the works, other than varied work. It

provides that if, in the opinion of the ‘engineer, the nature or amount of any varied work

relative to that of the whole of the works, or to any part thereof, is such that the rate or

price contained in the contract for any item of the works, is rendered inappropriate or

inapplicable, then a suitable new rate or price is to be agreed upon between the engineer

and the contractor. This provision extends, therefore, to the rates or prices for ‘any item of

the works’ and affects the rates or prices which are influenced by variations due to time

delay, out of sequence working, changes in the method of execution and to a large extent

the preliminary items of the bill of quantities, if any are included. For a proper adjustment of

the rates and prices of these items, if such adjustment is found to be necessary, reliable

knowledge and understanding of the make-up of these rates and prices is essential.

Once again, agreement on new suitable rates or prices is to be attempted under the

provisions of sub-clause 52.2 after ‘due consultation’ by the engineer with the employer and

the contractor. In the event of disagreement, the engineer is required to fix such other rate

or price as is, in his opinion, appropriate in the particular case. The engineer is then required

to notify the contractor accordingly with a copy to the employer. As previously required

under sub-clause 52.1, until such time as rates or prices are agreed or fixed, the engineer

should determine provisional rates or prices to enable on-account payment to be included in

any certificate issued under clause 60.

The fourth way in which a variation may be valued applies where it is to be found, on the

issue of the taking-over certificate for the whole of the works, that the value of varied work

together with all adjustments upon measurement of the estimated quantities is in excess of

15 per cent of the ‘Effective Contract Price’. The ‘Effective Contract Price’ is defined in

sub-clause 52.3 of the Red Book as ‘the Contract Price, excluding Provisional Sums and

allowance for dayworks, if any’.

Then, a sum is required to be added or deducted from the contract price as may be agreed

between the engineer and the contractor. There is no guidance in the Red Book as to how

this sum should be calculated. It is, however, apparent that the target of such adjustment is

the bill of preliminary items which forms part of the contract price.

On page 117 of the Guide, referred to in Reference at srl. no 12, there is reference to the

purpose of this sub-clause where it is explained that ‘in preparing a tender, a contractor may

distribute his on-costs and profit in various ways,...’, and an adjustment of these is

necessary where the amount of work under the contract is varied beyond the specified

percentage. For an accurate adjustment, however, it is imperative that the engineer should

obtain details of the contractor’s internal price make-up of these on-costs and profit items.

f.

Sub-clause 52.3, which deals with the situation where the value of variations exceeds 15 per

cent of the effective contract price, defines the value of varied work and all adjustments

upon measurements of the estimated quantities in the following manner:

varied work is defined in paragraph (a) of sub-clause 52.3 as all varied work valued

under sub-clauses 52.1 and 52.2. This definition removes the confusion which existed

in previous editions of the Red Book as to whether or not changes of quantity arising

from measurements, in accordance with clause 56, should be included in the

calculation of the value of the varied work. It is now clear that only varied work in

accordance with sub-clause 52.1 and 52.2 should be included;

i.

all adjustments upon measurement of the estimated quantities is defined in paragraph

(b) of sub-clause 52.3 as those adjustments which are ‘set out in the Bill of

Quantities, excluding Provisional Sums, day works and adjustments of price made

under Clause 70’.

This definition also clarifies in precise terms the value of additions to or deductions

from the ‘Effective Contract Price’, or in other words from ‘the Contract Price,

excluding Provisional Sums and allowance for dayworks, if any’;

ii.

agreement between the engineer and contractor is once again based on the new

concept of ‘due consultation’ by the engineer with the employer and the contractor.

Where no such agreement can be reached, the sum to be added to or deducted from

the contract price is required to be determined by the engineer having regard to the

contractor’s site and general overhead costs of the contract. The engineer, having

determined such sum, is required to notify the contractor accordingly with a copy to

the employer;

iii.

finally, sub-clause 52.3 provides that the sum to be added to or deducted from the

contract price is to be based only on the amount by which such additions or

deductions are in excess of 15 per cent as fixed in sub-clause 52.3. This provision

answers the question which was left unanswered in the previous editions of the Red

Book. It is now clear that the adjustment to the contract price should be related only

to the margin below or above the 15%. Therefore, if for example, there is a reduction

of 20% in the contract price due to the valuation of variations under sub-clauses 52.1

and 52.2, the ‘losses’ sustained by the contractor due to this reduction should only be

related to the margin between 20% and 15 per cent, i.e., 5 per cent and not the

whole of the 20 per cent.

iv.

g.

Sub-clause 52.4 deals with the situation where the engineer requires certain varied work to

be carried out on a daywork basis. Daywork is usually covered by a pro- visional sum in the

bill of quantities which may then be used for additional items for which no bill item is

applicable. Where such a provisional sum is included in the bill of quantities, a daywork

schedule of rates and prices is appended to the bill for pricing by the contractor. The

procedure for payment in respect of daywork is set out in sub-clause 52.4.

h.

Therefore, in setting out comprehensively the manner in which variations are to be valued, the Red

Book provides a remedy in the form of financial compensation in the anticipated event of a change

to the works being instructed by the engineer, on behalf of the employer.

Conclusions

It is expected that the Arbitrators will find the above analysis useful in interpreting the provisions

than searching the meaning from the similar Standard Forms of Contracts.

Though other clauses of the contracts are equally important but this paper is confined to only such

clauses which are often a matter of debate before the Arbitrators and the Courts.
