(a) the initial period should be the longest period for which a fair and appropriate fixed price can be negotiated; Each subsequent price period must be at least twelve months. There are many advantages to using a fixed-price contract in the construction sector. One of the main reasons why this is so common is because of its simplicity – companies are willing to pay a higher day in advance to avoid, with billing contracts open every hour or daily and the cost of the equipment. Both the company and the contractor know in advance the exact costs of commercial construction, which encourages contractors to ensure accuracy during the tendering process. However, there are several potential drawbacks to the use of a fixed-price contract in the commercial construction sector. First, it can be very difficult to make an accurate estimate in advance, so many contractors give themselves financial leeway to plan unexpected costs and ensure that they make enough profit for the investments they make. This is why many fixed-price contracts will be priced slightly above market value. Economic adjustment may take into account increases or decreases in a fixed and agreed price level, a real cost or a price index.  As contractors are able to attach a price tag to the project as a whole, it allows companies not to get bogged down in tedious details and gives the contractor greater freedom in its day-to-day operations. For many companies, the potential increase in total customer base and turnover, due to the simplicity of estimating fixed-price contracts, outweighs the mark added to the contractor`s price.
(c) Since this type of contract does not encourage the contractor to control costs other than the price of the cap, the contractor should, in the pre-contract discussion, make the licensee understand that the contractor`s effectiveness and ingenuity will be taken into account in retroactively setting the price. A truly “fixed” price contract would not necessarily be in the customer`s best interest, as it would require the contractor to have price risks over which he or she may have no control and which may not arise. b) The contract should only be awarded after negotiating a settlement price as fair and appropriate as circumstances permit. This means that the seller has agreed to provide work for a fixed amount of money. This type of contract is often used by government contractors to control costs and put the risk on the seller`s side. Thus, sellers who comply with fixed-price contracts have legal obligations to conclude the contract, otherwise they will have to make financial debts if they are not able to deliver. Under this agreement, buyers should define the products or services they offer, so that the buyer can set a fixed price on the delivery items. b) The planned redefinition of the price for subsequent benefit periods at a specified time or date during the performance. A fixed-price contract is a binding contract for both parties, which aims to set your energy prices at any port of your choice, regardless of future market movements. “lump sum” contracts are sometimes referred to as “fixed price” or “fixed price” contracts, even if this is not correct per se. A fixed-price contract sets an overall price for all construction-related activities during a project. Many fixed-price contracts include early termination benefits and late termination penalties to encourage contractors to ensure that the project is completed on time and on time.
