Determine the 4-hour duration probable maximum precipitation (PMP) for a 60 km2 catchment with smooth terrain centred on Stroud. Determine the temporal pattern for the storm? Present the temporal pattern as a bar graph of rainfall depths vs time over 30-minute intervals.

Please advise on both of tendering method and contractual arrangement for the construction of a 5-Star Hotel in Tung Chung new town. Since the proposed project is to be a major development, the Client is anxious on the cost aspects.

The Client wishes to have indication of the amount of investment before signing the formal contract with the selected contractor and he is also concerned on the cost-control aspect. He also intends to commence the work at a reasonable time.

Suggest to the client with reasons, for choosing both of the most appropriate tendering method and contractual arrangement for this particular project for client’s consideration.

I need answers on 3.2.4

3.2.3 If the air temperature is 15°C and the relative humidity 35 percent, calculate the vapor pressure, specific humidity, and air density. Assume standard atmospheric pressure (101.3 kPa). 3.2.4 Solve Prob. 3.2.3 if the air temperature rises to 300C. By what percentage does the specific humidity increase as a result of the temperature rise from 15 to 300C?

A conventional non-aerated lagoon with a hydraulic retention time of one year is used to treat domestic sewage in a wastewater treatment plant. The plant needs to be upgraded to handle a larger wastewater flow rate and to improve the removal of nutrients. List three treatment system upgrades (by using process diagrams)  that can be done to the existing lagoon, and provide a schematic diagram for each upgraded process. What do you think the best choice between the three upgrades you suggested is and why?

presentation in Pavement

*You are required to prepare a short presentation (not more than 12 slides) in power point format regarding the subject that will be assigned to you. The subject is related to pavement distresses in flexible and rigid pavements.

*Every student will be required to collect comprehensive information about the distresses assigned to him (see the table in the next page). The information should include, but not limited to, distresses definition, causes, severity levels, measurement method, maintenance procedures and preventive measures.

*Your presentation should include the above items supported by figures, schematics, or any clarifying tools

*You are required to use at least 3 references for you work (books, journals, or internet). In order not to violate copy rights and plagiarism rules all resources and references should be listed in the last slide.

*Comprehensiveness, clearness and neatness of the content are key elements in the evaluation

* MY topic is (Lane to shoulder drop off + separation in rigid pavements ) *

1. three storey structure having a square footprint of 225 m² is constructed on a clayey deposit. The structure is planned to be supported by square isolated footings having a width of 2m and spaced at 5m center to center. typical borehole indicates that the soil consists of 2m fill layer at the top (g=17KN/m³) followed by a very stiff clay layer 2m thick (gsat=18.5KN/m³) underlain by a normally consolidated soft clay layer of 4.5m thickness (gsat=17KN/m³) followed by a rock layer extending down to the bottom of borehole. The foundations are laid on top of the stiff clay layer. Water table is located at the top of the stiff clay layer. Undisturbed samples were taken from the middle of each clay layer and consolidation tests done on undisturbed samples indicated the following:

 Stiff Clay: Cc=0.15; Cs = 0.02; P_c = 120 kPa; e₀=0.9

 Soft Normally Consolidated Clay: Cc=0.38; Cs = 0.06; e₀=1.0

a) The isolated foundations are subjected to a stress of 140 kPa. Calculate the consolidation settlement. Consider the very stiff clay as one layer and divide soft clay layer into two equal sub-layers. Calculate settlement under one typical foundation.

b) What would be the maximum additional stress applied on a central foundation from two neighboring foundations (situated at the left and right sides of the central foundation). Is it necessary to consider the additional stresses from neighboring foundations in the settlement calculations?

c) A concern is the differential settlement between isolated adjacent footings. It was decided to change the design to have the structure founded on a raft foundation subjected to a stress of 45 kPa. Compute the consolidation settlement and comment on the results.

In discharge over V-notch experiment, calibration curve (using log Q vs log H) is plotted. How would you interpret results which, when plotted logarithmically, fall on a line which is not straight but slightly curved? and, What are the effects of a change in the V-notch angle on the discharge equation and the accuracy of flow measurement?

a- • Must a contractor be delayed beyond the contractual project duration in order to successfully file a claim for 15 delay damages? • Explain your answer

b- • A contract contains the following clause: • “The owner specifically reserves the right to modify the progress schedule as required by the conditions of the work.” Can a contractor that has been delayed by the owner’s revisions to the order of the work in the schedule successfully file a claim for a time extension? • Explain your answer

c- • What is the role of “as-built” schedules in litigation involving delays?

d- • To minimize the chance of losses, suggest a methodology to follow when a delay, that has the potential 18 of resulting in litigation, occurs on a construction project.

e- • Explain two of the added costs that might be incurred by the contractor as a result of a change issued by the owner.

Water flows through a cast iron pipe with a diameter of 30 mm. The pipe is inclined at an angle of 3 degrees from horizontal and is 40 m long. The water flows due to gravity only. What is the maximum volume flow rate of the water?

You may ignore any minor loses.

Two vehicles travel along two distinct roads. The first vehicle traveled in the first roadway
with a spot speed equal to “A veh/hr”, while the second vehicle traveled along the second roadway
with a space mean speed equal to “A veh/hr”. If the two vehicles originated at the same position
and will arrive at the same points, who will arrive at the destination first? Elucidate, and
expound your idea based on the fundamental definitions and your logical reasoning.

What considerations and designs exist when planning and creating a system for potable water (for drinking fountains) + sewage water (for bathrooms) at an off-grid site with a well source? Please include a diagram if possible with explanation, and then discuss benefits of dry flush and composting toilets compared to the traditional toilet system.

Project title is 3D printed Buildings.
Question is who will be our targeted consumers and who can be the stake holders ? As well please let me know the aim and objectives of this project.
