Construction

Payment

How are payments to contractors, design consultants and subcontractors normally structured?

Angola

Angola

Payments under a construction contract are normally made against the certification of partially completed works by the works supervisor, which usually happens monthly. In fixed price contracts, the works to be delivered and payments to be made are normally set out in a works and payment schedule.

In public works contracts, the tender documents usually provide the method of payment.

Methods of payment vary according to the works. The four main types of contract sum are calculated as follows:

  1. Lump sum: The contract sets out a pre-agreed sum that the contractor/consultant/sub-contractor will be paid to carry out either a stage or the whole of the works that are required under the contract (subject to various provisions, including variations for which the contractor may receive additional monies)
  2. Measurement: The work is measured and valued according to a formula or schedule of rates
  3. Cost plus: Payment is by prime cost plus an added percentage for profit
  4. A combination of the above for example the base works may be a lump sum but variations may be carried out on a measured basis

For each of these methods, payment is usually made against the certification of completed works by the contract administrator. The inspection and certification of completed works can be made on a periodic basis (usually monthly) or a milestone basis (at pre-agreed specific milestones or stages).

Each Australian state and territory now has legislation dealing with security of payment for contractors, suppliers and subcontractors in the infrastructure industry and for those who provide related goods and services (such as engineers and architects).

While the detail varies from state to state, the SOP legislation has the following features:

  • It enshrines a statutory right to payment for infrastructure work and services. In some jurisdictions this right is granted even if there is a similar existing right in the relevant infrastructure contract. In other jurisdictions it is only granted if the relevant contract contains no payment regime.
  • It specifies a process which must be followed by both the party claiming under that statutory right, and the party who is liable to make payment.
  • It prohibits ‘pay when paid’ clauses and other clauses considered adverse to a contractor’s right to be paid for work carried out.
  • It prescribes a type of fast track dispute resolution in the form of adjudication of payment claims under contracts.

Some SOP Acts (such as those enacted in the Northern Territory and Western Australia) give a party a right to claim payment in respect of the work or services only if the relevant contract does not contain any provision for payment.

In other SOP Acts, notably those in Victoria, New South Wales and Queensland, the statutory right exists regardless of the presence in the applicable contract of provisions giving a right to a party to claim payment for work and services. This statutory right sits in parallel with the contractual right to payment.

The SOP legislation enacted in Australia has the following important impacts:

  • It ‘speeds’ up certification of payment claims and requires contractors to have efficient contract administration processes.
  • It improves the cash flow to subcontractor and suppliers, and means that contractors cannot rely on delaying payment to sustain cash flow and liquidity.
  • It may have reduced the number of major disputes as many of these may be resolved at the adjudication stage.

Depending on the jurisdiction in which the works are being carried out, most construction and infrastructure contracts need to contain provisions dealing with SOP.

Such provisions will not be standard, as careful consideration needs to be given to the nature of the project and how the payment provisions are intended to work. For example:

  • In some jurisdictions, imposing a pre-condition on payment of a contractor or subcontractor, such as the provision of insurance details or security, may be in breach of the relevant SOP Act.
  • Not all construction work is covered by the relevant SOP Act. Notable exclusions to the operation of the SOP Act in most jurisdictions are mining work, residential building work and work where the payment under the contract is not the value of the work performed but some other mechanism (as may be the case in a build own transfer project).
  • There still exists in some jurisdictions legislation which gives contractors a right to place a charge over monies payable to the contractor (in the case of Queensland) or a lien over property to secure payment (in the case of South Australia).

Most contracts determine a payment schedule whereby payment instalments are due in proportion to the progress of the works. Some contracts foresee the circumstance where the contractor is required to submit pro forma statements by way of a payment procedure or structure, which is to be approved by the architect or principal within a set period, after which the contractor can accordingly submit his invoice.

The Law of 9 July 1971 which governs house construction and the sale of houses to be or being built, contains a number of specific mandatory provisions which deal with payments and which are to the benefit of purchasers.

Bosnia-Herzegovina

There is no strictly defined mode of payment. The parties to the contract are free to decide and agree on such issues. Payments are most commonly made on completion of agreed stages of development.

Canada

Canada

Several payment methods exist in order to compensate the above-described parties. Some of the methods of payment are described below.

Contractors and sub-contractors

For contractors and subcontractors, the most common payment methods are lump sum, cost plus a fee, and cost plus a fee with a guaranteed maximum price.

Lump sum

The contract sets out a pre-agreed sum that the contractor/consultant/sub-contractor will be paid to carry out either a stage or the whole of the works that are required under the contract (subject to various provisions, including variations for which the contractor may receive additional monies).

Cost plus a fee

Under a cost plus fee arrangement, the owner pays the contractor for the entire cost of the work, including, without limitation, the cost of engaging workers (including employee benefits), equipment, materials, supplies, supervision etc The owner also pays the contractor a fee representing the contractor’s profit and other items, such as office overhead. The fee can be a percentage of the cost of the work or a lump sum. If the fee is a percentage, then the fee generally will increase or decrease as changes are made to the scope of the work through change orders or construction change directives (see Variations). If the fee is a lump sum, then any additional fee will have to be provided for in the change order or the construction change directive.

Guaranteed Maximum Price

A guaranteed maximum price is the cost plus a fee compensation structure (immediately above) but with a not-to-exceed price guaranteed by the contractor. If the cost of the project exceeds the guaranteed price, then contractor must complete the project and bear responsibility for such excess costs. If the cost of the project is less than the guaranteed maximum price, then the difference between the guaranteed price and the actual cost becomes savings and may be shared in an agreed-upon proportion between the owner and contractor.

Variations exist on the above as well. For example, under the cost plus a fee, the contractor might agree on a not-to-exceed price for the general conditions costs. Under any of the above methods, the contractor might agree not to charge a fee for changed work unless the changed work exceeds a certain dollar amount. In such a case, the contractor might agree that it is not entitled to a fee until the dollar amount of change orders exceeds a specific collar amount (called a ‘fee holiday’ or ‘dead band’).

A schedule of values also may be used to determine that payment remains on course during course of the construction loan. In such a case, a schedule of values listing the trades and other activities on the Project is made, together with the amount then due such parties.

Design consultants

For design consultants, payments are generally made periodically in accordance with a method agreed upon by the parties in the governing agreement. For design work, the phases of work might be assigned a certain value of the entire contract price (eg $X for the schematic design phase, $Y for the design development phase, $Z the construction document phase, $A for the bidding and negotiation phase, $B for construction administration phase, and possibly $C for sustainable design). Within a phase, the parties might agree that the design professional will receive a pro rata share of such value corresponding to the amount for that phase.

Lien Legislation

Each jurisdiction in Canada has legislation that grants those who supply construction services and make improvements to the land a charge against the owner of the land. This type of charge is referred to as a ‘builders’ lien’, ‘mechanics’ lien’ or ‘construction lien’ depending on the jurisdiction. Although the legislation differs in each jurisdiction, the main purpose of the legislation is to provide payment protection for sub-contractors and material suppliers. Owners are required to holdback a certain portion of all payments made under the contract with the contractor. In the event of a claim by a subcontractor for payment, such payment amount can be paid out of the holdback in priority to other claimants. Subcontractors can also register a claim of a builders’ lien against title to the property on which the project was constructed. Certain jurisdictions provide for liens against chattels in addition to liens against the property.

China

China

There is no standard payment structure for contractors or design consultants. Some agreements provide for payments to be made in stages (including the obtaining of key permits). Other agreements provide for payments to be made on the basis of hourly rates.

Croatia

Methods of payment vary according to the works. The three main types of payment are:

  1. Lump sum: A pre-agreed sum that the contractor/sub-contractor will be paid to carry out either a stage of or the whole of the works that are required under the contract (subject to various provisions, including variations for which the contractor may receive additional monies)
  2. Measurement: The work is measured and valued according to a schedule or formula
  3. Advance payment: An advance payment is made for the costs of the labour and/or materials used

Payment is usually made after the supervising engineer (appointed by the investor) has certified the completed works. The inspection and certification of completed works can be made on a periodic basis (usually monthly) or a milestone basis (at pre-agreed specific milestones or stages).

Czech Republic

Czech Republic

All payment issues depend on the agreement between the parties. However, in the case of larger projects, gradual financing in the form of advances in connection with the completion of individual sections of the works is normally applied. The final payment is usually transferred after the handover of the building or very often held as a security in the form of a deposit which is paid after the lapse of the warranty period.

Denmark

Denmark

According to the general conditions in the standard form construction contracts, AB 18 and ABT 18, the total contract sum can be paid under two different systems:

  1. Upon written request to the employer, the contractor is entitled to receive payment twice a month for work performed.
  2. Instead of payment from the employer twice a month, the parties can agree on payment being effected in accordance with a payment schedule which follows the time schedule and stipulates at which time the contract sum or parts thereof are to be paid.
France

France

The parties are free to provide for any method of payment (lump sum, measurement, a schedule of payment etc). Payment against measurement is most common.

The owner (maître d’ouvrage) shall either provide for a direct payment by the bank to the contractor in the event a loan was secured by the owner to finance the construction works or deliver a joint bank guarantee equal to the entire price of the contract to the contractor (entrepreneur) in order to secure the payment obligation owed to the contractor.

The owner is entitled to retain an amount not exceeding 5% of the entire price of the project in order to guarantee the remediation of any defects arising on the date of acceptance of the works.

Germany

Germany

The contracting parties may agree on various pricing arrangements. The following terms are provided for by the contracting rules for the procurement of public works (VOB/B):

  • The unit price (Einheitspreis) is a price per unit of measurement of the quantity of work and services. The unit price depends on the estimated total quantity, which is estimated in the specifications and price schedules. 
  • A fixed price (Pauschalpreis) is a total price for the entire carrying out and completion of the construction contract without any further assessment of the works actually provided. 
  • According to the VOB/B hourly rates (Stundenlohnsätze) are only paid if expressly agreed in the contract beforehand. Such an arrangement is extremely disadvantageous for the principal since it pays for any shortcomings in the organisation, quality and diligence of the workers.

Payments are usually made in instalments according to the progress of the works already carried out. In relation to defects, the principal can make retentions or even refuse to pay instalments, Section 16 para. no. 2. Usually the construction contract sets out the payment schedule, the instalments and the effects of defects to the payment claims. Advance payments are usually secured by bank guarantees. The final account (Schlussrechnung) ensures the final settlement of the project, and precludes any subsequent claims.

The principal is only obliged to remunerate the contractors engaged by it directly. Where sub-contractors are engaged, these are not remunerated by the principal but by the relevant contracting party (ie the general or prime contractor or other sub-contractors). Sub-contractor agreements mostly follow the payment arrangements described above. 

Hong Kong

Hong Kong

Methods of payment vary according to the works. The four main types of payment are:

  • Lump sum: a pre-agreed sum that the contractor(s) will be paid to carry out the scope of works stated in the contract (subject to the terms and conditions of the contract which provide for adjustment of payment under certain circumstances).
  • Measurement: the work is measured and valued according to an agreed schedule or formula.
  • Prime cost: payment is made for the costs of the labour and materials used.
  • Cost plus: payment is by prime cost plus an additional percentage as profit.

Payment is usually made when the works are completed. However, it is common for the contractor to have the right of payment by instalment or interim payment in the progress of the construction as it gives the contractor funding for the performance of works and supply of materials during construction.

As an alternative to the interim payment, a lump sum contract may provide for milestone payment. The employer will make periodic payments to the contactor by reference to certain stages of the work or stated intervals. In other words, the milestone payment approach makes interim payments subject to achievement of predetermined progress milestones.

Hungary

Hungary

Although the method of payment is subject to the parties’ agreement, the most typical scenario is that payment is made after completion of each milestone.

Fixed-price contracts are common in Hungary, although other payment and calculation methods are also in use, including prime cost and cost plus fee arrangements. The contractor may become entitled to additional payment(s) if variations to the original technical specifications are requested by the employer.

To ensure that the funds earmarked for certain construction and building activities are used for the purposes specified in the construction contract, the Construction Act, requires the employment of a project fund manager for construction works exceeding the value of €5,548,000. The most important aspect of ‘project fund management’ is that the funds to cover the costs of the construction works must be deposited into a separate account accessed exclusively by the project fund manager who is responsible for the distribution of these funds to the contractor and sub-contractors. Construction concessions and works awarded through public procurement are not subject to ‘project fund management’.

Parties can freely decide on methods and terms of payments in a construction or design contract. In small and short-term projects, payments are commonly made at the completion of the construction work. In large and long-term projects, payments are commonly made at the completion of agreed stages of construction.  In public works, certain percentage of the contract price is often paid to a contractor before starting the construction.

Netherlands

Netherlands

There are various ways in which payments can be structured between parties (charging net costs plus fee, fixed price, etc). The most clear-cut method is the situation in which the client pays all parties (contractor, architect, structural engineer) separately. Another possibility – particularly in respect of private housing – is that the private buyer pays the contractor who must, in turn, transfer the payment to the developer.

Nigeria

Nigeria

Generally, payments are structured in phases or stages. The contractor upon completion of each phase submits an invoice for the works and the employer on confirmation of the works issues a certificate of completion whereupon the payment is made to the contractor.

The parties may agree an advance payment to the contractor of a sum representing 10% of the total contract sum for mobilization and commencement of the works which is deducted from payments due to the contractor under the contract. Usually, there is provision for retention from each payment due to the contractor for the purpose of rectifying defects after completion of the project or paid back to the contractor upon certification by the employer’s architect that all defects have been rectified by the contractor.

This mode of payment may also be adopted for design consultants where their responsibilities run for the entire span of the project duration.

The responsibility of paying subcontractors is on the contractor and this is also structured in line with payments upon successful completion of each phase or stage of the works until completion of the specific subcontractors’ contractual obligations.

Portugal

Portugal

Contractors and sub-contractors are generally paid as they perform their obligations and carry out the works. To this end, construction milestones are agreed and payments are made if, and when, the milestones are met by the contractor. If the parties agree, a third party entity (typically a quantity surveyor) may be appointed to assess the works, for payment purposes. In public works contracts, payments according to construction milestones are the general rule. Each time part of the construction is completed, the parties calculate the value of the works carried out and a corresponding payment is made to the contractor.

Romania

Romania

Normally, in a construction contract, the price is pre agreed, taking into consideration an estimate of the costs. The employer makes an advance payment, as an interest-free loan to facilitate mobilization and the contractor submits a guarantee. The rest of the price will then be paid in instalments.

The total advance payment, the schedule of payments, and the applicable currencies and proportions, are stated in the construction contract.

A construction contract may only lay down the criteria for the subsequent determination of the price. In this situation, the works are measured and valued for payment by the engineer.

Furthermore, generally, a performance guarantee of 10 percent of the price is withheld. The performance guarantee is usually returned to the contractor in the following tranches:

  • 5 percent at the handover of the completed construction works if there are no defects identified
  • 5 percent at the final delivery at the end of the guarantee period if no defects have been identified
Russia

Russia

The payment structure should be set out in the construction contract. In its absence, the price is to be paid upon completion of the works.

To determine the payment procedure, the construction contract will usually use one or a combination of the following:

  • Advance payments of the amount specified in the construction contract
  • Periodic (usually monthly) payments made against certification of acceptance of various stages of the works
  • A bonus payable if the development is completed ahead of schedule, and/or
  • Amounts held back to be paid upon a building being put into operation or upon completion of a testing period
Slovak Republic

Slovak Republic

Methods of payment will vary according to the works. The four main types of payment are:

  • Lump sum: A pre-agreed sum that the contractor/consultant/subcontractor will be paid to carry out either a part or all of the works as required under the contract
  • Measurement: The work is measured and valued according to a schedule or formula
  • Prime cost: Payment is made for the costs of the labour and materials used
  • Cost plus: Payment is based on prime cost plus an added percentage for profit

Under the contract, the client will be bound to pay the contractor the price within the agreed time period. Unless the contract or Slovak law provides otherwise, entitlement to payment arises following the execution of the work. However, this does not prohibit the parties agreeing on another payment time or method, for example, a payment made following the approval of the completed works.

Spain

Spain

Payments under a construction contract are normally made against the certification of partially completed works by the works manager, which usually happens monthly. In fixed price contracts, the works to be delivered and payments to be made are normally set out in a payment schedule.

An inspection of the works in order to authorise a payment does not normally imply either acceptance or delivery of the works.

Commonly, payments are reduced by 5 percent, with that amount being placed in a deposit account aimed at guaranteeing the quality of the works.

Payments to professional consultants may be calculated in accordance with the recommended practice of the relevant professional society (eg the Society of Architects), and are normally made on delivery of the documentation or on a periodical basis.

Sweden

Sweden

The price can either be fixed or set according to prime cost principle. The prime cost principle refers to certain works, including cost of materials and goods, cost of la-bour and cost of sub-contracts etc, as stipulated in the General Conditions for Con-tracts - AB 04 and ABT 06. Usually the plan of payment is set so that the contractor gets paid after carrying out certain elements of the works. Normally the employer withholds 10 percent of the total price until the contract works have been approved by a final inspection.

Thailand

Thailand

There are various methods of payment, each of which is stipulated in the construction contract.

The payment will generally be made on an installments basis in connection with the progress of each stage of the works. Once the works have been inspected, the payment to the contractor will be made in accordance with the payment dates agreed upon and outlined in the construction contract. In addition, unless otherwise provided in the contract, a retention is usually required in order to guarantee the remediation of any defects incurring after the date of delivery of the works.

The Housing Grants, Construction and Regeneration Act 1996 introduced a more certain system for payment. This was aimed at facilitating cash flow throughout the course of the contract. It requires every construction contract to provide an adequate mechanism for determining what payments become due, when they become due and a final date for payment. It also introduced the concept of ‘payment notices’ and ‘pay less notices’. The party claiming payment (the contractor or consultant) is required to issue payment notices. These must state the amount it wishes to be paid (these notices often take the form of contractual applications for payment). If the paying party (the employer) wishes to pay less than the sum notified in the payment notice, it must issue a pay less notice setting out the sum the payer considers to be due on the date the notice is served (which can be zero), and the basis on which the sum is calculated.

The Housing Grants, Construction and Regeneration Act 1996 sought to introduce a more certain and satisfactory system for payment, aimed at facilitating cash flow throughout the course of the contract. It requires every construction contract to provide an adequate mechanism for determining what payments become due, when they become due and a final date for payment. On 1 November 2011, the Local Democracy, Economic Development and Construction Act 2009 came into force and amended the payment regime for contracts entered into on or after 1 November 2011. The Housing Grants, Construction and Regeneration Act 1996 as amended by the Local Democracy, Economic Development and Construction Act 2009 sets out a two notice system. The first notice is intended to fix the amount due to be paid. The second notice must be issued by the paying party if it wishes to pay less than the notified sum.

Ukraine

Ukraine

Generally, most construction contracts in Ukraine contain a clause providing for advance payments that should be paid to the contractor before the commencement of construction works. The rest of the contract price is usually divided into payments that are made on completion of specific stages of the construction works or periodically (eg monthly). The final retention payment is usually paid within one to two years after the completion of construction (after the expiration of the construction guarantee period).

Several payment methods exist in order to compensate the above-described parties. Some of those methods are described below.

Contractors and sub-contractors

For contractors and subcontractors, the most common payment methods are lump sum, cost plus a fee, and cost plus a fee with a guaranteed maximum price (known as ‘GMAX’):

Lump sum

See fixed price contracts.

Cost plus a fee

Under a cost plus fee arrangement, the owner pays the contractor for the entire cost of the work, including, without limitation, the cost of engaging workers (including employee benefits), equipment, materials, supplies, supervision etc. The owner also pays the contractor a fee representing the contractor’s profit and other items, such as office overhead. The fee can be a percentage of the cost of the work or a lump sum. If the fee is a percentage, then the fee generally will increase or decrease as changes are made to the scope of the work through change orders or construction change directives (see variations). If the fee is a lump sum, then any additional fee will have to be provided for in the change order or the construction change directive.

GMAX

A guaranteed maximum price is the cost plus a fee compensation structure (immediately above) but with a not-to-exceed price guaranteed by the contractor. If the cost of the project exceeds the guaranteed price, then contractor must complete the project and bear responsibility for such excess costs. If the cost of the project is less than the guaranteed maximum price, then the difference between the guaranteed price and the actual cost becomes savings and may be shared in an agreed-upon proportion between the owner and contractor.

Variations exist on the above as well. For example, under the cost plus a fee, the contractor might agree on a not-to-exceed price for the general conditions costs. Under any of the above methods, the contractor might agree not to charge a fee for changed work unless the changed work exceeds a certain dollar amount. In such a case, the contractor might agree that it is not entitled to a fee until the dollar amount of change orders exceeds a specific collar amount (called a ‘fee holiday’ or ‘dead band’).

A schedule of values also may be used to determine that payment remains on course during course of the construction loan. In such a case, a schedule of values listing the trades and other activities on the Project is made, together with the amount then due such parties.

Within a phase, the parties might agree that the design professional will receive a pro rata share of such value corresponding to the amount for that phase.

Payment to contractors are regulated by the unique agreement between the parties. Thus payments depend on sources of finance and the agreement between the contracting parties.
