Since a lump sum contract includes a total price without taking into account the actual costs, the contractor should do this price better correctly. The sum comes from comprehensive plans, detailed design specifications, and a bit of confidence. A guaranteed maximum price or a refund contract usually includes a 5% contingency in the contract, while a fixed price does not. Therefore, the price of a GMP contract is always higher than the fixed-price contract. A contractor`s detailed estimate for each construction project includes the following. We offer a series of more than 50 construction project management templates for construction project managers and civil engineers. So don`t waste your critical time recreating formats from the bottom up and use our professionally developed and tested templates. These templates help to make the project successful, save time and many project resources. There are pros and cons to everything. Here are some disadvantages of the flat-rate construction agreement.

The advantage of a Cost Plus contract for a contractor is to benefit from a refund for all expenses in the workplace. The changes do not have as much impact on their profits as in the case of a lump sum agreement. The project can change and evolve, which can be a great advantage for an owner. However, the owner does not always take advantage of it. Since the contractor has a certain degree of autonomy under this agreement, it can and must obtain supplies for the equipment at the best price. Dishonest contractors may try to replace low-quality materials to get their profits from the project. Such agreements should be complemented by provisions to adequately compensate contractors for project inflation, in particular those that last a long time. The reason for the offer is based on the current price and, in the event of a price change that occurs throughout the period, the contractor should be paid. In contradiction with fixed-price contracts, these projects rarely have a predetermined number. They can quickly become out-of-control trains whose total cost is much higher than the owner expected.

The example of the lump sum contract in which the customer unsubscribes from paying additional fees for indefinite work. Therefore, the provisional sum clause is useful to be considered as an estimate of the total fixed price of the contract. The paperwork associated with a contract is much less detailed than for most other contract forms. There is less need for the contractor to provide lists of ventilated materials or to provide the owner with offers for subcontracting and suppliers. This lack of ventilation allows the contractor to carry forward costs and conceal its real benefits. Unbalanced offers are common for contract projects. The contractor shifts part of the profit on the material or work mark-up in order to hide its actual profit margin from the owner. While a lump sum is a lump sum, this lack of transparency may allow the contractor to increase its price a little if we consider that it never has to present an invoice individually to prove its costs.

The flat-rate contract must include the appropriate mechanism to prevent fluctuations in inflation. The contractor should therefore receive an inflation allowance for long-term projects. There are several examples of a contract contract for construction projects. The most common are: there are certain situations and projects in which lump sum contracts can be the best choice for all parties involved. Generally speaking, projects that work best under fixed-price contracts have two essential factors: when a lump sum project is over budget, the contractor bears all cost overruns. The owner no longer pays when the price of materials increases. When a problem arises that requires additional equipment or work, the price does not change. All these additional costs are the responsibility of the contractor.

Compared to certain other types of contracts, the lump sum agreement carries a high risk for the contractor, since the method of preparing the contract is more costly for the contractor. . . .
