Site survey, design and construction, embodiment of technology, process and management
Site survey, design and construction are mainly for supporting works of base stations, such as towers, equipment rooms, earthing systems, power supply systems, fences, and civil works, etc. During the project planning, site investigation, standardized design, output of base station model and construction proposals are provided as the basis of network planning and engineering budgeting. During the project implementation, technical survey and detailed design for base stations offer guidelines for work items and construction.

SITE LAYOUT
BUILDING LAYOUT
The objectives of surveying for building construction are to lay out the proposed structure according to prepared plans and to mark the controlling points of the structure in the manner that is most useful to the construction forces. This marking consists of indicating the corners of the building and other horizontal and vertical positions by means of stakes, batter boards with string lines, drill holes, cut-and-fill notations, and similar conventional methods.
The actual layout of the building is usually preceded by some form of reconnaissance and location survey.

Setting out is the first stage of construction in a site. This involves outlining the structure on the ground. For any new house or extensions or alterations mapping out is very important to avoid costly errors. There are factors to consider when laying out the building plans on site. This include the size of the plot, neighbors, driveways and sun direction. The other factors to note are planning requirements by the local authorities and services required to the site. This are electricity, water, sewers, communication and roads.

"Locação" means lease or rental. As miers suggested, I think this is a BOT contract: Build, Operate and Transfer (lease).

"O sistema de contrato B.O.T. (Build, Operate and Transfer) ou (Construir, Operar e Transferir) é uma parceria que visa atender as necessidades do cliente, isentando-se de investir recursos próprios ou assumir responsabilidades fora de sua atividade-fim, transferido para uma empresa especializada todo o risco inerente ao processo de prospecção, captação e tratamento de água / efluente."
