Describe the problem of lack of coordination between design and construction in a traditional contract.In agency CM,what expertise does the CM provide during the pre-design and design phase?In agency CM,what expertise does the CM provide during the construction phase?Describe what the CM does in CMAR.Explain why having a single party to contact is an important aspect of design-build.List three potential benefits of using the design-build approach.List four things that should be included in the general information section of an RFP?Discuss the disadvantages of using the best value procurement.Discuss the formation of teams and consortiums.Explain why the need for good scheduling and planning of construction projects becomes more acute as construction projects become more complex.Describe the CPM backward pass.Describe at least four basic features of CPM software.Describe the CPM and project cost control.Describe the budgeted cost of work performed(BCWP).Discuss how complexity influences the cost of a construction project.
The pressure drop in a 10 cm galvanized iron horizontal pipe (ks=.15mm) carrying water over a length of 50 m is 30 kPa. What is the flow rate
A cutting 9 m deep is to be excavated in saturated clay of unit weight 19 kN/m3. The design shear strength parameters are cu = 30 kN/ m2 and ?u = 0. A hard stratum underlies the clay at a depth of 11 m below ground level.
The truss shown consists of 9 members and is supported by a ball and socket at A, two short links at B, and one short link at G. Check that this truss is a simple truss, that it is completely constrained
Determine the normal capacity of the highway, the capacity of the highway upstream of the work zone, and the capacity within or in the vicinity of the work zone.
An asphalt mixture is placed and compacted. Two tests are taken from the compacted mixture and checked for density. Core 1 had a density of 2403 kg/m3 and an air void content of 6.5%. Core 2 had a density of 2419 kg/m3.
A large concrete channel holds a hydraulic jump in which the subcritical depth of flow is 2.5 m. If 40 percent of the specific energy in the flow is lost through the hydraulic jump, what is the specific discharge in this rectangular channel
(a) Determine the distance d to the point where he lands. (b)What are the magnitudes of his components of velocity parallel and perpendicular to the 45 degree surface just before he lands
Sandwhich structures are obviously very efficient in bending applications. Would they be equally efficient in tensile or compressive loading? Explain your answer in terms of area available for carrying tensile-compressive loads.
