Lump Sum Construction Contract Definition

Lump sum contract is defined as a fixed price contract where contractors undertake to be responsible for executing the complete contract work for a stated total sum of money.

A lump-sum agreement/contract will require the contractor to agree to provide specified works for a fixed price. In this type of contract, the client has essentially assigned all the risk to the contractor, who in turn can be expected to ask for a higher markup in order to take care of unforeseen contingencies. A Contractor being contracted under a lump-sum agreement will be responsible for the proper job execution and will provide its own means and methods to finish the work

When to Use Lump Sum Contract Agreement

A lump-sum contract is a great agreement to be used if the requested work is well-defined and construction drawings are available. The lump-sum agreement will reduce client risk, and the contractor has greater control over profit expectations. A lump sum is preferred when there is a stable soil condition, complete pre-construction studies, and assessments are completed and the contractor has analyzed those documents. When agreed-upon partiesThe lump sum type contract may contain, certain unit prices for items with indefinite quantities and allowance to cover any unexpected condition.

The time to award a lump sum contract is also longer; however, it will minimize change orders during construction.

This is generally appropriate where the construction project is well defined, when tenders are sought, and significant changes to requirements are unlikely. This means that the contractor will be able to accurately price the works they are being asked to carry out.

Variations in Lump Sum Contracts

Compared to some other types of contracts, the lump sum agreement allocates high risk to the contractor because the contract preparation method is more costly for the contractor. Therefore, a clear system has to be put in place to address varying conditions during the course construction by adding necessary provisions:

1. Variations

Although the amount of work and its price are well defined, there is always scope for modifications or upgrades in a lump sum contract. Agreements should include conditions for contractors to carry out such design, material or quantity changes without having to argue about costs to cover these modifications.

It’s important that contracts include an efficient variation and valuation process.

2. Relevant events

This may include failure on the part of the client to procure supplies or providing the contractor with timely orders or those occurrences that are not controlled by either party such as inclement natural disasters or weather. In either case, such clauses should be included in the contracts that provide reimbursement for losses to the contractor.

3. Provisional sum

This is applicable in cases where the client may not opt to pay for undefined work. That’s why the contract documents include a provisional sum as an estimate of the total construction cost.

4. Fluctuations in Inflation

Provisions should be added to these agreements in order to adequately compensate contractors for project inflations, particularly those that last for a long time. The reason for tenders is based on the current price, and in the event of a price change that happens throughout the period, the contractor should be paid.

Disputes in Lump Sum Construction Agreement

Lump sum contracts are suitable for smaller construction projects and may result in disputes and claims resulting from contractual agreements. The most disputed problems are:

1. Unbalanced Bids

Some projects must submit requests for payment using amounts of units and prices of units. In this case, by raising unit prices on such items required early in the building process as transportation and insurance, the contractor may make the bid to be unbalanced and reduce the unit price on materials to be used later.

2. Change Orders

In case of change order proposals suggested or received by the client that may demand increased expenses, the rate quotation could lead to disagreements.

3. Changes related to Scope and Design

The contractor may suggest modifications in design based on construction processes & previous experience. Contract provisions should be able to explain how those alterations in the plan will be addressed & who will bear the add-on expenses.

4. Compensation for Early Completion

Lump sum contracts may include a provision to compensate the contractor for early completion.
