Part I: It deals with the scope of work, construction rules and conditions, and is divided into the following paragraphs, which are applicable to the transaction part: consultation, scope, related work, system description, quality assurance, document submission, transportation, storage and management, site conditions, construction period, candidates, allowances, unit price and license.

part ii: products. Describe the materials and equipment used in production: allowable manufacturers, materials, equipment, mixture and assembly.

Part III: Detailed requirements for workmanship, quality and installation: supervision, preparation, installation, on-site quality control, debugging and cleaning, care, accessories and construction period. In bidding, the contractor collects all documents to determine the project quotation. If the standard format is used, the contractor can focus on the differences from the standard. Designers should do everything possible to organize information so that unique aspects of work can be easily identified. Otherwise, the contractor will miss important details, so as to change the quotation structure of the project. Omission or misunderstanding only helps the project. If the relevant information is hidden in the document, it is meaningless to claim that the contractor should have found the details. Legally, the contractor is obliged to provide the scope specified in the document. The owner and designer shall do everything possible to ensure that the contractor has covered the characteristics of the project. Dissatisfied contractors will not be good partners.

In addition to preparing clear and organized documents and holding pre-bidding meetings, designers and owners should reconsider the quotation together with the low-priced bidder and discuss the special aspects of the work. This will ensure that the contractor has enough funds to start the project and then complete the project as designed and planned. After receiving all the bids, the construction manager made the data into a spreadsheet. Table 7.5 shows the arrangement numbers of electronic watches for quick comparison. Comparison items include pre-tender estimate, candidates, appendix, unit price, excluded items, qualifications and valuation suggestions. At first glance, the table shows that CGS is the lowest bidder even if the alternate is removed. However, before deciding to win the bid, the owner and the construction manager should carefully check the assumptions about the quantity of materials in the CGS pre-tender estimate.

Part II

Because the prices of other contractors and labor are not much cheaper, the unit price is higher than in principle. The scope of review helps to identify whether the company has made mistakes. If the contractor really holds the correct scope, the owner and the construction manager should also consider: If the modification based on unknown conditions (for example, asbestos in the wall) occurs, how many times will it take before the lower bidder with more cost-effective data than the current lowest bidder appears? Owners and managers should check their expectations about unknowable conditions, which is to determine the scope. And measure the bid according to reasonable expectations about the change.

if the price provided by the bidder exceeds the plan and specifications, the engineering team needs to decide how to deal with it. Usually, according to the following principles: if a low-priced bidder, even if there is no candidate, nominates a candidate with a comparable price or a better candidate, and the proposal makes the bidder's price lower, then the owner can accept the bid; If the bidder whose price is not low nominates an unequal but acceptable candidate, so that the bidder's asking price is low, then the owner can give other approved bidders the opportunity to bid for this candidate. If the bidder's asking price is neither low nor low, and an acceptable candidate is nominated, then the owner can ask the bidder to price the candidate. The award of a contract can be as simple as accepting the lowest bidder, and ultimately. However, many factors will come into play after receiving the tender. The obvious lowest bidder may not be the lowest in the end. The lowest bidder may be too far away from other bidders to make people suspect that he has missed something. According to the law, in any case, bidders must abide by the price; But at work, there is no shortage of people who don't work well. Received tenders often lack information: for example, important receipts, appendix confirmations, signatures and exclusions. The above example does not describe all the situations. In any case, the owner has the right to refuse or accept the bid. Small mistakes of employees can usually be corrected and forgiven; But on the whole, if the bidder fails to meet the requirements of the tender, his bid will be rejected.

the bidding process is a painful moment for the owners and designers. In most cases, if the bidder's estimate is higher than the available funds for the project, then no one will win the bid. The normal procedure is to redesign or reduce the scope until it does not exceed the project budget. However, these are only estimates, not real prices. Owners can test the market with higher valuation, hoping that the pressure of competition will lower the price.
