There are three basic sources of productivity: labor, management, and technology. Construction projects present the construction manager with many challenges. Among them is the coordination of material, equipment, finances, and labor that must come together to produce the desired output. The analysis of any construction project will show that the construction manager is seeking to manage resources effectively and efficiently in order to complete the project. Those managers that seek understand human behavior and apply the principles of motivation theory to motivating the construction worker can benefit through improved productivity.

According to the passage, how can the labor productivity source be enhanced?

- Construction machinery
- Managing resources effectively
- Applying motivation theory principles
- Paying dividends to workers

The correct answer is C.

According to the text: "Those managers that seek to understand human behavior and apply the principles of motivation theory to motivating the construction worker can benefit through improved productivity."

If a car fails a VIC because its identity cannot be confirmed, it won't be entitled to retain its original registration mark. It may be possible to register the car with DVLA if evidence of British National Type Approval in the form of a Minister's Approval Certificate can be produced. This may be obtained by applying to VOSA for an Individual Vehicle Approval (IVA). However before doing so, you'll need to obtain an alternative vehicle identification number (VIN) from the DVLA Local Office.

According to the passage, what must first be done to receive an approval certificate?

- Acquire an alternative identification number.
- Register at the Minister's office.
- Register at the DVLA.
- Supply evidence of BNT approval.

The correct answer is A.

According to the text: "However before doing so, you'll need to obtain an alternative vehicle identification number (VIN) from the DVLA Local Office.

What would be the next number in the following series?

91 92 93 96 95 100 __?__

- 94
- 97
- 98
- 104

The correct answer is B.

There are two alternating sequences in this series, each following a different rule:

The odd terms (indicated in red): increase by 2.

The even terms: increase by 4.

The equation used to transform units from degrees Fahrenheit (˚F) to degrees Celsius (˚C) is ˚F = 9/5 (˚C) + 32. If the temperature is 40.0˚C, what is the approximate temperature in degrees Fahrenheit?

- 83.1˚F
- 102.9˚F
- 104.0˚F
- 45.5˚F

The correct answer is C.

To solve this question, Place the given temperature (40.0˚C) into the equation:˚F = 9/5*40 + 32 = 72 + 32 = 104.

A 6-foot long piece of card board is cut into 4 equal sections. How long is each section in inches?

- 9 inches
- 18 inches
- 16 inches
- 36 inches

The correct answer is B.

To solve this question, you first need to convert the card board size from feet into inches. Since 1 foot = 12 inches, the length of the card board equals 72 inches (6X12=72). Now that we know the size in inches, we can now divide the piece of card board into 4 equal sections, and find that each piece equals 18 inches – since 72/4 = 18.

A 5-foot by 10-foot by 9-foot Swimming Pool is filled with 2 pipes with a uniform flow. The first pipe fills the pool in 25 hours. Both pipes working simultaneously fill the pool 15 hours faster than the first pipe alone. What is the least amount of time required by the second pipe to overflow the pool by itself?

- More than 14 hours and 20 minutes.
- More than 15 hours and 5 minutes.
- More than 16 hours and 40 minutes.
- There is insufficient information to answer this question

The correct answer is C.

The question can be solved by simply examining each pipe’s rate of filling the entire pool: Rate of pipe 1 is 1 pool per hour: = 1/25 Rate of pipe 1 + pipe 2 = 1/(25-15) = 1/10 Let X represent the number of hours it will take pipe 2 to fill a pool: 1/25 + 1/x = 1/10 X = 16.67

Solving Tips: The question could also be solved by calculating the volume of the pool (although it is not most efficient way and is essentially unnecessary), like shown below – so if you did, please note you were correct:

- First calculate the volume of the pool, which is 450 cubic feet (5 X 10 X 9 = 450).
- Now that we know the volume, we can calculate the work rate (power) of the first pipe using the power equation: Work Rate = Volume/ Time, thus – the work rate for the first pipe is 18 feet per hour (450 / 25 = 18).
- Since we know that both pipes fill the pool simultaneously within 10 hours, we can now calculate the time needed for the second pipe to fill up the pool, by using the same equation for work rate shown before: 10 * (18 + Work Rate) = 450, 10*Work Rate = 450 – 180, 10*Work Rate = 270, Work Rate = 27 feet per hour.
- To get to the time needed by the second pipe to fill up the pool, we now divide the pool’s size by the second pipe’s work rate, and so we get: 450/27 = 16.66, which means 16 hours and two thirds of an hour (which is, 40 minutes since each hour consists of 60 minutes) – which is the minimal time to overflow the pool.

You have been asked to build a fence around a plant and you have the following information:

- The plant’s formation is circular
- The plant has no roof.
- The fence must be at least 40 feet high so security cameras installed later by the technological team could capture all necessary activity.
- The fence can be built of wood, stone or steel.
- The fence should be painted in white or yellow.
- The plant must have 2 or more electric gates.
- The width of each gate must be at least 20 feet.

What additional information would you need before you get a minimal bank loan for buying the material needed for the job?

- The cost of yellow or white paint per gallon.
- The price of an electric fence.
- The number of square feet that can be covered by one gallon of exterior paint.
- The price of wood, still bars, cement and bricks.
- The kind of security cameras installed later - thermal, infra-red night vision, or ordinary.
- The work hours in the plant.
- All of the above.
- Some of the above.

The correct answer is F.

In order to answer this question, you need to analyze the necessity of each piece of additional information mentioned to calculate the minimal cost of materials needed for the job.

For the sake of simplicity, we will now analyze each sentence in a table:

Sentences | Necessary | Unecessary |
---|---|---|

The cost of yellow or white paint per gallon. | + | |

The price of an electric fence. | + | |

The number of square feet that can be covered by one gallon of exterior paint. | + | |

The price of wood, still bars, cement and bricks. | + | |

The kind of security cameras installed later – thermal, infra-red night vision, or ordinary. | + | |

The work hours in the plant. |

Since we can easily deduct why all sentences mentioned above as necessary are needed to calculate the minimal price for materials, we will only explain why the last to sentences are not:

- The kind of security cameras installed later – thermal, infra-red night vision, or ordinary – since we are dealing with work which will only be conducted later by the technological team, the price of cameras will not included in the budget for building the fence. We therefore do not need this information even though it might influence the total cost of work.
- The work hours in the plant – although it might influence the construction workers salary, at this stage we only seek information regarding price of materials.

Item Price | Starting Inventory* | Office Supplies Usage During the Fourth Quarter | ||||

Floor G | Floor 1 | Floor 2 | Floor 3 | |||

Mineral Motor Oil | $16.25 | 53 | 7 | 13 | 11 | 7 |

Synthetic Blend | $12.20 | 23 | 4 | 6 | 2 | 2 |

Synthetic Motor Oil | $2.35 | 128 | 32 | 25 | 28 | 36 |

Brake Fluid | $1.05 | 184 | 50 | 61 | 66 | 39 |

*Inventory status at the start of the fourth quarter.

- How many cans of synthetic blend should you order so as to have 25 cans of oil in inventory at the start of the next quarter?
- 14
- 16
- 18
- 20

The correct answer is B.

Since a total of 4 + 6 + 2 + 2 = 14 cans of synthetic blend were used during the fourth quarter, after the quarter there will be 23 – 14 = 9 cans of synthetic blend left. In order to have 25 cans of synthetic blend, 25 – 9 = 16 cans of synthetic blend must be ordered.

- What will be the value (in terms of Item Price) of the synthetic motor oil in inventory at the end of the fourth quarter?
- $16.45
- $19.40
- $20.45
- $22.10

The correct answer is A.

Since a total of 32 + 25 + 28 + 36 = 121 cans of synthetic motor oil were used during the fourth quarter, after the quarter there will be 128 – 121 = 7 cans of motor oil left. Each can of synthetic motor oil costs $2.35, so the remaining cans will be worth 7 * $2.35 = $16.45.

Which of the shapes above needs to be combined with shapes x and y in order to create the upper leftmost shape?

- A
- B
- C
- D
- E

The correct answer is B.

A gas turns into liquid when it is:

- condensed
- heated
- saturated
- compressed

The correct answer is A.

Since condensation is the change of the physical state of matter from a gas phase into liquid phase – the correct answer is a. Please note that condensation is the reverse action of evaporation.

Resistors are used to control the flow of:

- electricity
- soundwaves
- vibrations
- fluids

The correct answer is A.

A resistor is an electrical component that acts to reduce current flow by implementing electrical resistance. Moreover, an example suitable to clarify this term is a dimmer switch, which is essentially a variable resistor controlling the intensity of light by manipulating the size of electrical resistance – and thus current flow.

Which of the 3D structures shown above, if made from the same metal and are of equal weight, is easier to balance on a stick?

- Structure A
- Structure B
- Structure C
- They are equally difficult to balance.

The correct answer is B.

In order to answer this question, we first need to understand the concept of center of mass, which is the point where the mass of an object is concentrated. By supporting an object as closely as possible to its center of mass – we can get it to balance, or – be in a state of equilibrium. If an object is irregular in shape, the center of mass is always located closer to the more massive end. By examining the different shapes, we can easily rule out both answers a and c – since their center of mass would be exactly in the middle as they are both symmetric shapes – thus making it more difficult to balance than the pyramidal shape, which will have a center of mass located near to its base – the massive end of it.
