NDSU CME 660 Infrastructure Management: Cost, Bidding & Sustainability

This assignment covers various aspects of infrastructure management, including economic evaluation, contracting methods, and sustainability. It begins with a problem involving the calculation of investment costs for controlled river discharge using different levee heights and interest rates. The assignment then delves into the differences between reconnaissance and feasibility studies, comparing A+B and design-bid-build contracting methods, and discussing the role of cost-benefit analysis in project determination. Definitions of infrastructure and sustainability are also provided. Finally, the assignment includes multiple-choice questions covering topics such as infrastructure planning, environmental impact assessments, and stakeholder involvement. Desklib offers a range of resources, including past papers and solved assignments, to support students in their studies.

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).

Answer to question 2:
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.
Answer to question 3:
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).

Answer to question 4:
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.
