Quantity take-off problem: A capital improvement project requires the installation of a property line fence along the 250 -ft northern boundary line. The decorative aluminum fence is constructed of posts spaced at 10-ft center to center and an ornate picket infill panel between two posts. Given the material costs below, the cost for the construction of the fence is most nearly:

a. $65,771.25

b. $66,461.60

c. $68,402.10

d. $71, 065.58

Material costs:

Aluminum posts: $645.35 each

Ironworker: $78/hr

Picket infill panel: $1,985.50 each

Placed concrete $498.00/cy

A CAT 834 (power-shift, wheel-type) dozer is used in a pushing operation. The dozer is equipped with a straight blade. The material is in a loose stock pile and weighs 80 pcf in the bank state. It is estimated that the material will swell 4 % from bank to loose state. The center-of-mass-to center of mass pushing is 250 ft on a 0% grade. The operators have average skill and the job will be performed in normal conditions. Job efficiency can be assumed to be equivalent to a 55-min hour. Calculate the direct cost (DC) of the proposed earthmoving operation in dollars per bcy. The normal O & O cost for these machines is $86.00 per hour and the operator’s wage is $12.50 per hour plus 35% for fringes, insurance, worker’s compensation, and so on. Assume that the dozer will have a 0.39 coefficient of traction*.

* For wheel-type dozer and coefficient of traction less than 0.40, decrease production by 4% per 0.01 decrease below 0.40.

Describe the two-way factorial ANOVA for independent means (i.e., factorial between-subjects ANOVA): What is the purpose of factorial ANOVA, what are independent or “unrelated” means, and what types of predictor/independent and outcome/dependent variables are required?

If you visit a construction site, which quality aspects should you check with respect to structural concrete?

1. Explain why principal arterials carry 50% of the traffic volume but only 5% of the highway system mileage.

. Assume a continuous function f(x) defined on x axis with a uniform grid spacing of h. The first and second derivatives of function can be approximated using information at more grid points giving rise to higher-order approximations. Using appropriate Taylor series expansions about location x, find the leading order truncation terms for the following approximations. Also indicate the order of accuracy for each approximation. Show all steps and box the final answers. Note: Look for the location at which a particular formula is written. For example, the first one below is at the location x. All your Taylor series expansions should be around x in this case. If a formula is approximating at x + h, all your Taylor series expansions should be around x + h (e.g. for part 4).

f(x + h) ≈ 2f(x) − f(x − h)

An arch dam has the following characteristics.

H= 22.2 m, L1=400m, L2=120 m, Find the thickness and projection on the crown cantilever and volume of the concrete.

Renaissance, in the sense of rebirth, occurs often in history. What was so special about the Fifteenth and Sixteenth century Renaissance to set it apart from all others so that the time period carries this title?
