Question 4
Engineers are planning to place a shallow foundation as shown Engineers have decided that loose sand and soft clay are not capable of supporting the foundation without being treated what is the best.
Correct Answer : b
Selected Answer : b
Explanation : CONCEPT (1) Pressure grouting or jet grouting involves injecting a grout material into otherwise inaccessible but interconnected pore or void space of which neither the configuration or volume are known, and is often referred to simply as grouting. The grout may be a cementitious, resinous, or solution chemical mixture. The greatest use of pressure grouting is to improve geomaterials (soil and rock). The purpose of grouting can be either to strengthen a formation or to reduce water flow through it. (2) Grouting in clay soils could easily result in an unsuccessful outcome because of a lack of good understanding of the rheological characteristics of grouts injected and the grout hose system. Additionally, for the purpose of lifting tilted building and/or structure, the dissipation of the excess porewater pressure generated during grout injection is likely to lead to a negative final compensation efficiency. (3) Dynamic compaction is suitable for densification of loose sand deposits. (4) Surcharge loading is suitable for clay -cohesive soil. (5) Vibro compaction is a ground improvement technique that densifies clean, cohesion less granular soils with a downhole vibrator. Hence to treat, Soft clay - Surcharge loading Loose sand - Dynamic compaction ANSWER Option B - B. Conduct dynamic compaction to treat loose sand and conduct surcharging to treat soft clay.

Question 18
The advantages of a Design/Bid/Build contractual arrangement is (are).
Correct Answer : b
Selected Answer : c
Explanation : CONCEPT Design-bid-build is the traditional low bidder model and is one of the most popular delivery methods. With this approach, the project owner establishes separate contractual relationships with the design team (architect and engineer) and the general contractor (GC) who will perform the construction activities. The method is straightforward enough for homeowners to stay on top of and understand. Unlike the design-build delivery, there is less collaboration between the design team and the GC, and thus design changes are easier to track. Owners can be fully engaged in the design process, while the design team and the contractor’s roles are more autonomous, and the responsibilities of each function are better defined. ANSWER Option B & C are correct- B. Non-adversary relationships among participants C. Known project cost before construction

Question 24
Which of the following situations requires a change order?
Correct Answer : d
Selected Answer : d
Explanation : CONCEPT In project management, change orders are also called variations or variation orders. Any modification or change to works agreed in the contract is treated as a variation. These modifications can be divided into three main categories 1. Addition to the work agreed in the contract. 2. Omission of work agreed in the contract. 3. Substitution or alteration of work agreed in the contract. A change order is work that is added to or deleted from the original scope of work of a contract, however, depending on the magnitude of the change, it may or may not alter the original contract amount and/or completion date. A change order may force a new project to handle significant changes to the current project. Change orders are common to most projects, and very common with large projects. After the original scope (or contract) is formed, complete with the total price to be paid and the specific work to be completed, a client may decide that the original plans do not best represent his or her definition for the finished project. Accordingly, the client will suggest an alternate approach. Common causes for change orders to be created are: The project's work was incorrectly estimated The customer or project team discovers obstacles or possible efficiencies that require them to deviate from the original plan The customer or project team are inefficient or incapable of completing their required deliverables within budget, and additional money, time, or resources must be added to the project During the course of the project, additional features or options are perceived and requested. If the contractor has to add work items to the original scope of work at a later time in order to achieve the customer's demands, a fair price for the work items and fees must be added for the materials and labor. ANSWER Option D - All the above
