Answer to question 1:
The word “reconnaissance” is majorly use by the armed forces for the monitoring activity. In this context the word reconnaissance denotes that the current scenarios. In the planning process, the planner needs to assess the current environment of the objectives and they cruciate monitor the components that they have to arrange so that the goals are attained. Further this is not only limited to monitoring rather this also scrutinise the possibilities and threats that might affect the planning procedure (Belle, 2017).
Whereas the feasibility study determines the viability on an idea. Moreover, it is the comparison of the plan with the justifiable legal, economic and technical forces. Which are necessary to be hold in consideration for the proper execution of the project. In the common sense, the words reconnaissance and feasibility are different on the projection of them. One is utilised before planning and the other one is after planning (Ashworth & Perera, 2018).
The A+B bidding contracts are commonly address as the cost plus time bidding. Form the definition it is clearly ascertainable that the bided contacts contains two components
- A- The cost of the bid ( investment)
- B= The time requirement to complete the project
In this type of project, the bidder must have made proper estimation of time and cost. Moreover, the contractor will focus on the effectiveness in the project execution.
Design-bid-build contracting means the designing, bidding and building process contracting. This is the traditional method of contacting which differentiated agency or the contractor will create. Every contractor is liable for different parts of the project like construction drawings, technical specification and others (Smol et al., 2015).
Both the study elaborates the methods of contracting. A+B method denoted the cost and time requirement but the design-bid-build contracting signifies and deliver every part of designing of the project.
In the project determination cost, benefit analysis is a significant part for the determination of benefits if the alternative option is used. This means the benefits, which will be enjoyable if the alternative process is utilised in the project. The strengths and the weaknesses are note down by this analysis. Furthermore all the projects requires the cost benefit analysis except where there is no alternative sources to evaluate or compare is available or the management has the confidence on the project or the project is new in the market and no substitute is available in that time (Zhou et al., 2015).
Infrastructure: it is the term, which is use to elaborate the structure of anything. The process, systems, workflows and other alternative are evaluate to determine the strengths of an entity, business, projects or planning procedure. The word infrastructure is use as the fundamental facility that needs to be deliver for the success of the project. The overall work procedure depends on the structural components, and this structural components are evaluated by the infrastructure (Fulford & Standing, 2014).
Sustainability: The word denotes the sustention ability. Which means the adopted procedure is eligible to provide the desired needs in the current situation, and the will be able to deliver the future needs (Goffee & Scase, 2015). In business environment the Sustainability means that the business is generating profits and contributing in the economy for a long period.
