An effective project control system is essential to the successful delivery of a construction project. Projects of substantial sizes or complexity need to be continually managed to guarantee any possibility of success. The project team uses control standards to continually check progress against acceptable standards. The study is aimed at studying building production control of materials in the Nigerian building industry. The study focused on articulating the existing knowledge on efficient and effective building production control of materials. Data were collected through the administration of a structured questionnaire to experienced professionals in construction sites and offices. The result shows that 60% of the sites use materials scheduling in controlling materials and the control planning is mostly carried out by quantity surveyors. It was observed that some of the major factors affecting qualitative building production control of materials are; poor planning of materials control, late delivery of materials to site, poor storage and poor material testing. It is recommended that; proper materials management will reduce time delay (delivery), cost of purchase, poor quality and thereby stopping wastes; building industries should have a prepared document for controlling building materials; an enlightening program should be conducted to educate people on the areas of material control; the three basic tool (planning material, scheduling and ABC analysis) should be included in controlling materials.

The nuclear containment acts as the final barrier against the release of radioactivity. Hence, its design, strict performance and safety evaluation under severe conditions are of great significance, whether through experiments or by numerical methods. In particular, the behavior prediction from functional to structural failure when the internal pressure is higher than the design pressure (Pd) is very important in terms of structural safety.

Structural steel grades are widely used in civil engineering applications in various product forms (bar or plates). Through the years focus is laid on how to obtain higher strength in combination with improved impact properties. In parallel, properties such as bendability and weldability are also considered. In this way, constructions comply with raising demands on improved performance under extreme conditions. A good way to achieve this is through the modification of phase transformations. This was achieved either via the Tempcore process, by which a martensitic and/or bainitic microstructure is obtained in the outer surface of the reinforcing bar. This high strength microstructure increases yield strength but reduces albeit ductility. Thus, its volume fraction has to be controlled. The ferritic/pearlitic core of the rebar is responsible for obtaining satisfactory elongation values. Moreover, microalloying elements such as vanadium (V), niobium (Nb), titanium (Ti) are added in steels to produce finer-grained microstructure, which increases the yield strength obeying the Hall – Petch equation while preserving higher elongation values. Nowadays, the need for tailored, more homogeneous microstructures with improved mechanical and technological properties, pave the way for the utilization of micro-alloyed steel bar and plate products.
