What are the typical ranges of drying shrinkage and creep strains in concrete; what is their significance?

The following are balanced interior angles to the right for a five-sided traverse. Given the Azimuth of course AB is 250°00’00”, compute and tabulate the azimuths for each side of the traverse. A = 82°13’15” B = 106°35’18” C = 28°45’06” D = 205°14’56” E = 117°11’25”

List the most important factors that affect drying shrinkage and creep, and discuss when the
effects are similar or opposite?

In a quality control test of a highway project, the following data was collected as shown below. Bulk specific gravity of the compacted mix is 2.30, Bulk Specific gravity of aggregate=2.75, The percentage of bitumen absorption is 0.45%, The percentage of binder by mass=5.5%,Bitumen Specific Gravity=1.05, answer the following questions: What is the percentage of Air voids in the compacted mix?

Aggregate effective specific gravity?

Please answer the following question.

a. How can you organizes and coordinates the daily operations of assigned staff to meet work goals such as ensuring activities are in compliance with all laws, policies, regulations and goals?

b. How can you demonstrate continuous effort to improve operations, decrease turnaround times, streamline work processes, and work cooperatively and jointly to provide quality seamless customer service?

c. How can you prioritize and coordinate work assignments such as training, coaching and instructs employees as required, monitor work and evaluates performance?

An unconfined aquifer made up of silt loam has an initial piezometric surface of 40 m. If wells 28 m and 15 m away from the pumping well have drawdowns of 4 m and 8 m, respectively, what is the pumping rate (m3/d) of the well?

Based on this, if you wanted to keep the same drawdowns at the observation wells, but needed a drawdown of 10 m in your pumping well, what diameter would the pumping well casing need to be?

A. An earthwork contract requires to cut and move excavated rocks. The site is a typical limestone rock formation in a cut section, which is 15,000 ft long, 85 ft wide, and 3 ft deep. Seismographic tests indicate a seismic wave velocity of 5,000 fps for the rock layer material. The contractor proposes to rip the rock with a 370-hp crawler tractor. Answer the following questions.

(a) Calculate the production in bcy per hour, for full-time ripping, with efficiency based on a 45         -min hour. Assume that the ripper is equipped with a single shank and that ripping conditions are average (i.e., intermediate between extreme conditions). This is classified as heavy ripping.

(b) Estimate the ripping unit-production cost in dollars per bcy using your calculated hourly production. The normal O&O cost per hour, including operator, for a tractor w/ ripper $130.00. The operator’s wage with fringe is $33.00 per hour.

(c) What is the total direct cost of the cut quantity?

(d) What is the total duration of the rock cut project assuming 10 hours per day work?

B. As a Construction Manager for this site development project, prepare detailed cost estimate for the project, and bid documents.

      Assume 10% time value cost of money, bonds, insurance, and storage over total direct cost, contingency at 2% of total direct cost, indirect overhead cost at 5% of total direct cost (additional on top of the equipment and operator costs), and 10% fee (on subtotal total of direct and indirect cost).

A horizontal Venturimeter with inlet diameter 300 mm and throat diameter 150 mm is used to measure the flow of water. The pressure at inlet is 24 N/cm² and the vacuum pressure (p₂)at the throat is 320 mm of mercury. Find the discharge and velocity through the pipe .The value of C_d may be taken as 0.98.

1. What does the Best Operating Point (BOP) of a pump represent?

2. Predicted system curves and measured system curves don’t always match. Manufacturer provided pump curves and measured pump curves can also differ. What are some reasons why?

Relate aggregates, concrete, asphalt, cement materials individually, and relate each material to the other materials. For example, how do they relate to a concrete or asphalt mixture? The goal is to demonstrate a thorough understanding of each material and their relationships to each other. Focus on a discussion and the significance of individual material groupings (aggregates, concrete (including Modulus Of Elasticity), asphalt, and cement), and explain in detail their importance to quality concrete and asphalt mixtures. Talk about “What, How, and Why.” Demonstrate a thorough understanding of each material.

1. A flyover was proposed for a heavy traffic area in order to channelize the traffic. How do you want to propose the location of storm water inlets to be connected to the sewers? Also, justify the need of the inlets on flyover. In case if they are not needed, justify the same as well.
