FOREWORD This technical guide was prepared in response to increasing concerns over the requirements for through-penetration firestopping as mandated by codes, specified by system designers, and required by code officials and/or other authorities having jurisdiction. The language in the model codes, the definitions used, and the expectations of local code authorities varies widely among the model codes and has caused confusion in the building construction industry. Contractors are often forced to bear the brunt of inadequate or confusing specifications, misunderstandings of code requirements, and lack of adequate plan review prior to construction. This guide contains descriptions, illustrations, definitions, recommendations on industry practices, designations of responsibility, references to other documents and guidance on plan and specification requirements. It is intended to be a generic educational tool for use by all parties to the construction process. Firestopping Guideline • Second Edition iii FIRE AND SMOKE CONTROL COMMITTEE Phillip E. -
Types of Piles: Their Characteristics and General Use BERNARD A
Types of Piles: Their Characteristics and General Use BERNARD A. GRAND, Hardesty and Hanover This paper presents a review of the current practice and usage of the numerous types of pile in general construction. Information on this sub ject was obtained from a review of existing literature and from field ex perience. The paper reviews the purpose of pile foundations and the various factors involved in the selection of a type of pile.. Emphasis is placed on the general, physical, and structural characteristics of the piles as well as durability and fabrication. Data are presented on the inherent advantages and disadvantages of the various types of piles and on corre sponding optimum pile length and load range. Information and data are presented on the field problems of pile installations and the proper meth od of handling and treabnent to avoid damage or failure of critical pile sections. The fundamental information is supplemented by case histories. •PILE FOUNDATIONS of timber were in use in ancient times. In its earliest form, a pile foundation consisted of rows of timber stakes driven into the ground. Pile founda tions such as these were used by the ancient Aztecs in North America. The Romans made frequent use of pile foundations as recorded by Vitruvius in 59 AD. Pile founda tions for ancient Roman dwellings have been found in Lake Lucerne. It is reported that during the rule of Julius Caesar a pile-supported bridge was constructed across the Rhine River. The durability of timber piles is illustrated ill the report of the reconstruction of an ancient bridge in Venice in 1902. -
Rational Design of Hollow Core Planks for Fire Resistance
Available online a t www.pelagiaresearchlibrary.com Pelagia Research Library Advances in Applied Science Research, 2012, 3 (5):2830-2836 ISSN: 0976-8610 CODEN (USA): AASRFC Rational design of hollow core planks for fire resistance Md Azree Othuman Mydin and Mahyuddin Ramli School of Housing, Building and Planning, Universiti Sains Malaysia, 11800, Penang, Malaysia _____________________________________________________________________________________________ ABSTRACT The utilization of precast hollow core plank systems in multi-storey buildings is prevalent these days. This is due to small onsite labour cost and high quality control. Precast hollow core planks are most extensively known for providing economical, efficient floor and roof systems. When properly matched for alignment, the voids in a hollow core planks may perhaps be utilized for electrical or mechanical runs. Among different precast plank systems, prestressed hollow core planks are the most well accepted system because of their lightweight nature and the economical use of concrete. Yet the structural behaviour of such systems under fire exposure is not clear-cut to be predicted because of the complex geometry, composite construction and an extensive range of possible support conditions. The aim of this paper is to discuss the characteristics of hollow core planks and the advantages of this system. Additionally, evaluation on the requirements and recommendations to the fire design of concrete planks from different standards will also be presented. These requirements will form the framework of future research focuses on providing a new method for the fire design of structures with hollowcore concrete plank systems. Keywords : Precast planks, flooring system, slab system, fire design, hollow core slab, fire resistance _____________________________________________________________________________________________ INTRODUCTION The precast concrete plank systems are becoming established and well accepted in many countries throughout the world due to low onsite labour cost and high quality control. -

Effects of Half-Precast Concrete Slab System on Construction Productivity
sustainability Article Effects of Half-Precast Concrete Slab System on Construction Productivity Kyuman Cho 1, Young-su Shin 2 and Taehoon Kim 1,* 1 School of Architecture, Chosun University, Gwangju 61452, Korea; [email protected] 2 Manager, Kunwon Engineering, Seoul 05855, Korea; [email protected] * Correspondence: [email protected]; Tel.: +82-62-230-7145 Received: 6 July 2017; Accepted: 17 July 2017; Published: 19 July 2017 Abstract: A half-precast concrete slab system (HPCSS) is reported to exhibit excellent structural performance when compared with traditional slab systems. However, there is a lack of extant research examining the construction issues of an HPCSS. Thus, in this study, we analyze the construction process and productivity of applying an HPCSS by using a simulation method with the data collected from an actual construction case. The results indicate that (i) the construction productivity of HPCSS is 1.7 times that of a traditional slab system, (ii) the cost per productivity unit of HPCSS exceeds that of a traditional slab system, and (iii) critical resources affecting the HPCSS productivity include form crew and rebar crew. The results of this study suggest that it is possible to develop an optimal construction plan of a construction site in which an HPCSS is installed, and that the HPCSS can be actively applied in the future. Keywords: half-precast concrete slab system; construction productivity; construction simulation 1. Introduction The construction industry is a highly labor-intensive industry facing several issues, including low productivity and construction quality. In order to overcome such problems, several researchers and practitioners have attempted to develop various methods to facilitate mechanical or manufactured procurements for a part of a facility, and this has subsequently led to the proliferation of automation technology in construction. -

Passive Firestop Systems Critical for Building Occupants
10/23/13 4:29 PM Passive firestop systems critical for building occupants By Gregg Stahl Instruments of active fire protection, such as sprinkler systems and fire extinguishers, are a common sight in most buildings – they are always located where building occupants can easily see and access them, if needed. Not as much attention is given to passive fire protection systems, embedded into interior building assemblies, away from public view. However, they are just as integral to the protection of the structure and its occupants in the event of a fire. A key component of commercial building design, passive fire protection's aim is to contain a fire at its source and prevent the spread of flames and smoke throughout a building to allow occupants more time to safely evacuate the structure. The most important area of concentration for these passive fire protection design strategies is the wall assembly, and the most effective mode of passive fire protection is the passive firestop system. Passive firestop systems Fire and smoke can travel through gaps in wall assemblies. Therefore, it is necessary to seal off any wall perimeter joints or penetrations for switches, electrical boxes, power outlets or the passage of pipes, cables or HVAC ductwork with firestop materials. Typically, these materials include: sealants, intumescent materials, sprays, mechanical devices and foam blocks or pillows. It is important to remember that there isn't one universal product that will work for every firestop application. It is also important to select products that have been tested appropriately to meet applicable fire safety standards. The two materials most commonly used in passive firestop systems for today's commercial building projects are sealants and intumescent materials. -

Precast Concrete – Environmentally Aware
[Year] Precast Concrete – Environmentally Aware How Green is my Concrete? Even when it's grey, concrete is green. Precast concrete's environmentally friendly features make it a building material of choice for sustainability.... meeting present needs without compromising the ability of future generations to meet their own needs. Whilst the manufacture of cement and concrete materials can contribute to greenhouse gas emissions, concrete is recognised as a material that is around for the long haul – tens if not potentially hundreds of years. Whilst it may have an “upfront” cost in carbon, over a longer life when other materials may get pulled down and rebuilt several times (and be sent to waste/landfill), concrete just keeps on keeping on. We also strive to make sure your precast concrete is made as efficiently as possible, locally and with minimal waste in the process, and with environmental and efficiency benefits realized wherever possible. Hudson Civil Products embrace the use of local products to minimize transport, undertakes various recycling and reuse projects as part of our waste stream management process, and have found solutions in a variety of other potential waste products being re-used and diverted for our use. Hudson Civil are continually looking for ways to improve the efficiency of our processes, recycle materials and even use industrial waste to produce eco-friendly concrete, including: 1. Source and use of appropriate local aggregates and materials to create suitable local-benefit concrete 2. Use local materials wherever possible, minimizing mixes with a minimum of “travel miles” to lower carbon emissions through reduced transport inputs, or both components and finished products. -
