The Effects Of Angularity On The Compaction And Shear Strength Of A Cohesionless Material, Richard Edward Swiderski
The Effects Of Angularity On The Compaction And Shear Strength Of A Cohesionless Material, Richard Edward Swiderski
Theses
Several physical methods are described for the practical measurement and rating of angularity (shape) of cohesionless soil particles. Angularity is determined by utilizing the fundamental property of a sphere: a sphere has the smallest contact surface area of any shape for a given volume. Therefore, any other shape will exhibit a greater contact surface area and consequently will have a greater frictional resistance which is a function of its degree of angularity.
The effects of angularity on the physical behavior (e.g. strength) of cohesionless soils was investigated at various relative compaction densities. For this purpose a combined compaction and direct …
Subcontracting By The Petrochemical Engineer-Constructor, Michael Peter Skurla
Subcontracting By The Petrochemical Engineer-Constructor, Michael Peter Skurla
Theses
An analysis has been made of the methods used by a Petrochemical Engineer-Constructor, who has national labor agreements, in deciding if the construction phase of a project should be done by a subcontract method of construction or be accomplished on a direct hire basis. The petrochemical complex under discussion is considered to be in the $75 million range for the total installed cost including design, engineering, procurement, and construction.
The influence of subcontracting portions of the construction phase by the Engineer-Constructor is reviewed with its impact on: the client; project schedule and cost; local and national labor relations, because of …
