THE BOT is widely used in infrastructure projects and public-private partnerships. Under the BOT, a third party, for example public administration. B, delegated to a private organization to design and build infrastructure and operate and maintain these facilities for a period of time. During this period, the private party is responsible for financing the project and is authorized to retain all revenues generated by the project and owns the entities under consideration. The facility is then transferred to the public administration at the end of the concession contract, without remuneration from the private entity concerned. Some, if not all of the following parts, could be involved in any BOT project: the development is then occupied by the client who leases to the contractor for a minimum term as part of a lease. The amount of rent generally depends on all development costs (including land acquisition, planning, construction and operating costs). In contract theory, several authors have studied the pros and cons of pooling the construction and operation phases of infrastructure projects. In particular, Mr. Hart (2003) used the incomplete approach to public procurement to determine whether incentives for non-contract investments are smaller or larger when the different phases of the project are grouped under a single private contractor.  Hart (2003) argues that incentives to pool cost-cutting investments are greater than dissociation. However, incentives to reduce costs can sometimes be exaggerated, as they lead to an excessive decline in quality, so that the fact that the consolidation or dissociation is optimal depends on the details of the project.
Harts (2003) The work has been extended in many directions.   Bennett and Iossa (2006) and Martimort and Pouyet (2008) study the interplay of consolidation and property rights while Hoppe and Schmitz (2013, 2020) examine the implications of pooling innovation.   BLOT (Build, lease, operate, transfer) is a model of a public-private partnership (PPP) project in which a private organization designs, finances and builds a facility on leased public land. The private organization manages the establishment for the duration of the lease and then transfers the property to the public body. Finally, the BLT sector has become a stage where even the EPC and O-M contracts between the project company and the contractors involved have been adjusted to some extent, because most of these agreements impose repayment obligations on contractors arising from the main project agreement between the project company and the Ministry of Health.  Lenders are also entitled to English law, which have a direct agreement with the contractors concerned, which strengthen their control over the contracts of the CBE and the O-M contracts. The BOT scheme refers to the initial concession of a public body such as a local government to a private company to build and operate the project in question. After a fixed period, usually two or three decades, control of the project is returned to the public body. With regard to the financial aspect, a number of agreements, often used in BLT projects, consist mainly of main and individual facilities agreements, agreements between creditors and another set of security documents under English and Turkish law.
