Executive Summary
The improved quality of services, better value for money and very significant saving in both project time and cost are clearly
manageable through detailed analysis. This may not be applicable to only individual stages of the entire process of construction but
also the interaction concept which exist between the two phases. In any engineering project or building, getting improvement through
careful consideration of the design, procurement, techniques of construction and approach of management should be aimed at making
the implementation easier, cheaper and quicker. This is actually a self-explanatory term in which there is a provision of the hourly
rates for every discipline. The billing procedure of the client is calculated as per the hours worked. This can be for every week, month,
year etc. This can be one of the best options as a contract where the scope has not been understood fully or there has been no finalized
program on the same. There is no risk involved from a contractor's point of view when working on rates that have been scheduled. All
the hours are fully paid, in some cases; the final costs of the projects are cheaper upon completion while using the rates that have been
scheduled

Introduction
It is the interest of all the experts of projects and the project owners (clients) to have the project completed on time and as per the
expectation of the shareholders. In order to achieve this complex and tricky goal, several factors must be considered and various
dimensions of the project must be properly defined within the boundaries of the project (Jarkas and Horner 2013).

Question 1
Supermarket Case Study Overviews
Locality: PNG Highlands
Clients: Retailers
Professional consultants: Mr. Samwel Crowe and Mr. Hayden Cessar
Contractors: Mario Casser
Building classification: Commercial building
Proposed or expected occupancy levels & description of the primary structural systems:
 Floor systems
 Roofing systems
 Fire protection systems
 Ceiling framing and grid layout
 Electrical and site plan
 Air Conditioning systems/legend
 Service legend

The expected occupancy level will be determined with cushion dimensions 42cm x 4cm x 5cm and this will depend on the location
and activities being conducted in the area.
Proposed Office and Work Development

Proposed or expected occupancy levels & description of the primary structural systems:
 Air Conditioning systems/legend
 Service legend
 Floor systems
 Roofing systems
 Fire protection systems
 Ceiling framing and grid layout

 Electrical and site plan
Question 2
Lump sum Contract
This is a kind of contract that has a fixed price for all the activities that are related to the construction. The contact is normally known
to include the penalties for the late termination or the incentives for the early termination. The application of the Lump sum contract
can be done in the cases where the project of the construction has a clear scope, a drawing of the construction and a proper outlined
schedule. This is common in the case of small and simple projects. In some cases, the owner could possibly have the orders changed
for work that is unspecified while at the same time take very high risks for taking back the credit for the work that is not completed.
Lump sum subject to rise and fall specifications.
A contract of the lump sum that has a rise and fall clause is that type of contact in which the risk of varying the cost can be possibly
shared with the client as opposed to being borne solely by the construction team who is the builder. This is different from the cases of
the industrial practices whereby the changes in the cost of the building cannot be passed to the buyer of the home
. It is, however, important to note that under S13(1) of the contracts of home building Act, the clauses of rise and fall are outlawed for
those specific contracts that are valued at less than a set amount. The present value of this figure is roughly $500000.The liability of
the builder who enters into such an agreement is equivalent to $ 10000 as a fine. The clauses of rise and fall can be used for those
contracts that are over the threshold.
