A back-to-back contract may refer to a variety of things, but it is most typically used in the construction industry.

Back-to-Back Contracts

A back to back contract may apply to a variety of topics, but it is most typically used in construction to signify that the primary project contractor expects their subcontractors to follow the original contract conditions. Back-to-back contract clauses may also be referred to as “integrated by reference” terms in this context (as opposed to newly drafted terms).

In general, “back-to-back” refers to any document that has all of the identical terms and qualities as the contract immediately after it. You may open a second letter of credit that has all of the same components as the first. In the context of housing development, the phrase may refer to dwellings that are erected next to one other.

What Are the Advantages of Using a Back-to-Back Contract?

Back-to-back construction contracts are frequent, particularly in major projects. Significant worldwide initiatives often need the involvement of a large number of people. When it comes to contributing to various areas of the project, everyone of these people is unique

The general contractor does not want to be fully accountable for all aspects of the project. As a result, they will try to transfer their duties and liabilities on to the project owner through their subcontractors. As a result, the principal contractor’s exposure to potentially problematic commitments is reduced. This is accomplished via the use of back-to-back contracts with subcontractors.

Back-to-Back Contracts: Drafting and Reviewing

Copies the necessary terms into the new contracts to include the principal contract terms into back-to-back (subcontractor) contracts. Exclude any provisions that do not apply, such as the total contract cost or any stipulations that only apply to the primary contractor. This approach of constructing back-to-back contracts may seem straightforward and efficient, yet it may be more complex than writing a single contract.

All provisions of the original contract that are relevant to the subcontract are included in stand-alone contracts. A contract of this kind may avoid time-consuming cross-references, errors, and inconsistencies. However, establishing a stand-alone contract may take much longer than drafting a back-to-back contract, since each party must study the agreements and determine which elements will be included in the subcontract and which will need to be adjusted.

You may also utilise a standard form subcontract, which is a contract form including pertinent terms from the original contract. You may, for example, utilise the FIDIC Subcontract for Construction for Building and Engineering Works Designed by the Employer, which is a globally accepted standard form subcontract designed to be used with the FIDIC Pink Book and the FIDIC Red Book, 1999 edition. The value of this sort of contract varies, however, since parties often change standard form contracts to match their own preferences, which may result in conflicts between the original contract and the subcontract.

Make a point of properly examining each contract provision when you develop or review back-to-back contracts. The following elements may be very important:

Additional payments and term extensions

Procedure revisions

Deadlines and specifications for completion

Limitations of Liability



Suspension and dismissal are also options.

Each party’s collaboration and coordination

Resolving Conflicts

Requirements for notification

Deadlines are critical.


The method of managing these issues may differ depending on whether the party is the major contractor or a subcontractor.

It is critical that each party carefully and completely reads the terms of the original contract to verify that all necessary clauses are incorporated within the subcontract and that terms are consistent throughout. Although the process may be tedious and time-consuming, it is recommended that each party examine the contractual terms sequentially and determine whether incorporating the term into the new contract will be effective and consistent (in a legal and commercial manner) and will certainly have the intended effect. Regardless of whether the subcontract includes the original contract by reference or was prepared as a stand-alone contract, this full walkthrough method is preferred.

Contracts Executed Back-to-Back Under English Law

A back-to-back contract that comprises terms by reference may not include certain types of provisions from the original contract to the subcontract under English law. Instead of relying on a default blanket incorporation by reference clause for certain sections, you may need to incorporate wording into the subcontract that conveys the required terms from the original contract. Other national and international regulations may also prohibit the inclusion of certain sections.
