 Design and build  
After reading the question, select whether it is true or false in the field beside it!
Designing with the elasticity theory is less economical than with the plasticity theory. True
False
Concrete cover can generally be less than the standard when designing space frame structures. True
False
Provisions for shrinkage stresses and temperature fluctuations during setting of concrete are being made at main reinforcement dimensioning. True
False
Slabs thicknesses are inversely proportional to the quantity of reinforcement. True
False
I-beams can have cut-outs in the web section for cable provisions, if cut-outs are kept circular in shape. True
False
Roof slabs of public covered swimming pools with great spans should be made out of steel frames. True
False
Compaction rate of road foundation material can be assessed with plate load tests or penetration tests. True
False
Shotcrete thicknesses shown on drawings are always indicating the minimum thicknesses to apply. True
False
RMR or Rock Mass Ratio can be a good rock stability and support indicator. The higher the RMR is, the more stable the rock should be. True
False
Roadheaders for rock excavation are generally only used when rock compressive strengths are over 20MPa. True
False
Vertical construction joints should always be provided where low or no bending moments are expected and should be chipped to guarantee bondage between old and new concrete. True
False
Sizes of prefabricated elements are only governed by the design analysis and not by hauling capacities. True
False
Every design should be influenced at early stages by the type of construction method chosen, and not the opposite. True
False
Design and built is the most economical construction and profit generated method of work for a Contractor. True
False
High-rise buildings are limited in their height due to the limit of compressive strength supported by the natural aggregate matrix before failure. True
False
Stiffeners and carefully placed hydraulic jacks can prevent bridges from entering in self resonance. True
False
Loading tests on friction piles are usually done by placing concrete blocks on a loading platform. Commonly all piles should be tested. True
False
Reinforcement mats are cheaper than single bars and usually more convenient for placing. True
False
Shop-drawings are produced to guarantee the buildability of theoretical design drawings. True
False
As-built drawings are a physical record of the actual site execution and conditions encountered and constitute the basis for construction defect liabilities claims. True
False
