Lump sum contracts distribute the risk to the contractor more than other types of contracts, as there are fewer mechanisms that allow them to vary their prices and give the customer some certainty about the expected cost of the work. The tendering process will tend to be slower than in other types of contracts and the preparation of an offer may be more expensive for the contractor. Lump-sum contracts are the simplest form of the construction contract. They are easy to create and easy to understand. Contractual documents must clearly state the work in question and the money expected by the contractor at the end of the project. As has already been said, flat-rate contracts are not always sunny and rainbow. Here are some of the main drawbacks. Projects that progress under a lump sum contract have, by their very nature, very few paper requirements. Payments are usually made according to a progress plan, so owners do not have to deal with equipment costs and hours of work. This means that contractors do not need to create detailed invoices or complex paid applications.
Payments are simple. The time frame for awarding a contract contract is also longer; However, it will minimize modification tasks during construction. What is Certified Payroll? This organization covers certified wage settlement requirements for contractors working on federal construction projects. However, a contract does not give the contractor the total risk of the project and it is not a fixed price, or even a guaranteed maximum price. The price of a contract can change. The completion of these activities requires significant planning and can represent a heavy capital burden for which the contractor can be paid in advance through a previously agreed mobilization fee (not separate from the lump sum contract) with the client. They may also include these fees in their first intermediate application. Contracts for the sum of money may be less appropriate if the speed is high or the nature of the work is not clearly defined. Other types of contracts that might be more appropriate in such circumstances are measurement contracts (used where work can be described in detail, but the amount cannot, cost reimbursement contracts (which can be used when the type of work cannot be properly defined from the outset, often used when an immediate start-up is required in the field) , destination contracts, etc. (see the purchase line for more information). There are several factors that contribute to the success of a flat-rate contract for a project, such as experience and trust, management capabilities, communication capabilities, a clear work plan, a correct list of results, contingencies and shared responsibilities between the project team.
 Customers benefit from the many benefits of this contract and the predictability of a flat-rate plan. Under the fixed price agreement, the owner`s liability and exposure during the construction period are limited. The contractor has opted for a sum and the owner cannot be held responsible for any of the overrun costs of the contractor. This means that there is a good amount of cost security, which is important for getting a construction loan. For the best chance of getting a project that goes smoothly, a contract contract requires clear work. The project must also be relatively simple, with as few variables as possible. In this scenario, a flat-rate contract works incredibly well for the contractor. On the other hand, a murky or muddy volume of work is a recipe for a payment issue under a lump sum contract. This type of agreement is quite simple to manage.
