Nowadays precast concrete elements are widely used in buildings, bridges, and other civil infrastructure facilities because precast elements allow rapid construction and high precision quality control. However, the quality inspection of precast concrete elements primarily relies on manual inspection, which is time consuming and error-prone. Recently, terrestrial laser scanner (TLS) has been use...

Precast concrete structures in Iran are generally designed as continuous columns with hinged beams, thereby making them simple frames. In this system in site show walls in two directions of buildings guaranteed lateral resisting system. However, in order to obtain a seismic resisting frame, the connection between beam and column should be moment resisting and ductile, allowing the formation of ...

PCI JOURNAL This paper presents the results of nonlinear fi nite element analyses conducted to model the behavior of L-shaped, precast, prestressed concrete spandrels constructed with open web reinforcement. The fi nite element model was calibrated using experimental results from recent tests of slender, L-shaped, precast, prestressed concrete spandrels. Detailed correlative studies between ana...

Research Question: Is the lean production philosophy applicable in precast concrete factories to achieve sustainability? If it is, what are the imperfections that can be improved to achieve sustainability? Purpose: This study aims to identify the contribution of the lean concept to achieve sustainability in precast concrete factories. By using appropriate lean principles, the precast concrete i...

The main objective of the present work is to study the present situation of the precast construction industry in India. Suggestions for improvement of the industry and study on cost effectiveness of precast concrete construction for single and multi-story residential buildings are to be given. A literature survey was carried out in order to obtain the comparison between the conventional buildin...

The Precast Concrete Industry (PCI) is one of the major contributors to the national economy and can be categorised as labor-intensive industry. It is currently experiencing shortcomings in terms of delivery products at a competitive cost and time. This is mainly due to the inefficiencies associate with planning and scheduling of skilled operators within crews configurations. This paper present...

ABSTRACT: With the advent of precast construction technology, the construction industry has seen a rapid change in the way structures are built. Precast construction has brought down project costs and durations, increased the predictability and improved the quality of construction. It has also resulted in a shift in construction tasks from the construction site to the factory floor. Precast ele...

We report on a large-scale effort to integrate advanced design and engineering information technologies (IT) in the North American precast/prestressed concrete industry. The effort has been undertaken by a consortium of precast producer companies formed specifically for the task. The effort involved significant process modeling work, using a unique method and set of tools. It led to the develop...

Lattice-girder floor slabs and double-wall elements have been successfully used in building and industrial construction for decades. These precast elements of 50 – 70 mm thickness serve as permanent formwork for the subsequently added in-situ concrete creating a monolithic structure. The high prefabrication level allows the construction period to be significantly minimized. The main goal is the...

Precast concrete material suppliers are responsible for the components that they manufacture from casting until up to 25 years after installation. To effectively manage the production and storage at a the production facility, to streamline the construction process and to quickly repair a component should there be a problem, information about components must be readily available and updated thro...
