For most dredging offers, a quantitative estimate is made for the materials listed. The bidder is required to indicate prices for each material per unit and, therefore, for the estimated total quantity. This assumes that the estimated quantities are correct, which is not necessarily the case. In general, the rule is that the rates represent overall all the activities that must be carried out by the contractor, and represent the price of the contract, We have already discussed the revaluation several times, but it is interesting to note that it is easy for an owner to compare an invoice with the expected price of the project units, because the price contracts per unit have costs so well broken down. Unlike other types of contracts where the behind-the-scenes pay premium is a behind-the-scenes process, the units are fairly transparent. This means that an owner can always be sure that he is calculated fairly and in accordance with his contract. Unit price contracts offer reciprocal benefits to the owner and contractor. If the owner has chosen a “good” advisor, he can count on the collection of quantities and accurate estimates of the schedule. With salaries set in advance, construction can begin before full planning is completed. This is ideal for projects where the volume of work can only be clearly defined after the completion of the construction work. With regard to the monthly progress count, unit price contracts are the best for quantifying the work performed. Differences from estimated quantities are expected to result in a proportional increase or decrease in the contract price. A “unit” represents a work block, materials or a combination of the two that are provided.
It can take any number of units to complete the entire order – and there will usually be an estimate of the number of units needed at the beginning of the order. Therefore, instead of looking at the project as a whole and setting a price based on that finished product, a unit price contract determines the price on the basis of the “units” needed to build that order. Often, the number of units needed is not really indicated at the beginning of the work. A unit contract is based on estimated quantities of materials for the project and their unit prices. The final price of the project depends on the quantities required to carry out the work. This means that before work and contract, the different materials are known, but the quantities cannot be identified. In a single-rate contract, the contractor offers a price for each material during the tender. The list of unit games per item can make it easier to calculate any changes or changes and avoid risks. In reality, however, this can be likened to a flat price. This is particularly the case when the proponent asks the contractor to accept the risk of a proper assessment of quantities, rather than allowing a reassessment of quantities in light of what happens on site during the work.
