Design and Construction Management

Design and Construction Management

An internship is a cooperative program between BYU-Idaho Design and Construction Department and approved Experience Providers (employers). Professional internships cor- relate actual work experience in the building construction industry with the architecture and construction coursework. Internships approved by the internship coordinator provide students with knowledge of career opportunities and actual work experience in prepara- tion for employment after graduation. The ideal internship would take place during the student’s off-track semester and be a full time, paid, employment opportunity. The length of time for your internship experience is intended to be equal to a 14 week semester, 40 hours per week or approximately 560 hours. Students should complete this internship course no later than between their Sophomore and Junior years for Construction Manage- ment degree seeking students and between Freshman and Sophomore years for those seeking an Associate degree in Architecture.

DESIGN and CONSTRUCTION STANDARDS

DESIGN and CONSTRUCTION STANDARDS

SECTION 1.0 INTRODUCTION 1.1 SCOPE The purpose "Water and Wastewater Design and Construction Standards" (Standards) is to provide procedures and minimum guidelines for the planning, design, and construction of water and/or wastewater systems for the Calaveras County Water District either as part of Capital Improvement Program (CIP) projects or as private development projects, which system(s) will be constructed and dedicated to the District. The Standards apply to existing water and/or wastewater systems being expanded, modified, upgraded, and rehabilitated as well as to the construction of new facilities. The District may require criteria that exceed these minimum standards based on project-specific conditions. Wherever there are differences between these Standards and other local, regional, County, State, or Federal regulations, the most stringent or highest requirement shall govern and be approved by the District Engineer.

Design & Construction Handbook

the client is able to specify quite clearly the building type, its functional requirements and certain financial or budgetary information relevant to the project, then we may say that the client approaches the designer with a set of needs that must be fulfilled. These needs may be simple or complex depending on the nature of the project, but they are inevitably both incomplete in a number of regards, and plastic, i.e., not yet fixed and rigid, but still capable of being changed or moulded as circumstances may dictate. As the project develops – from the general requirement for a shopping centre to the design of this particular shopping centre – then some of the needs may be modified. Indeed, and as might reasonably be expected, many requirements will emerge within the project that were previously unknown to the client and would not have formed part of the general list of needs. It is presumably one of the key roles of designers, and a condition of their expertise, that they will be able to identify, advise on and deal with such contingent needs specific to the individual project. Two simple examples will illustrate this point. Firstly, each specific project is built on a specific site, and specific physical site conditions, including soil type, slope, orientation, access and surroundings, will contribute to the requirements to be met by the designer in a variety of ways. Secondly, that the very notion of a specific physical location will introduce a series of statutory regulations with which the future building will be expected to comply, from specified height limits and percentage allowable site coverage, to requirements related to fire safety and egress provisions, or to the number of on-site car parking spaces that must be provided, and/or a range of factors addressing heritage, environmental, aesthetic and social concerns. All fall within the purview of the designer and all may be understood by the client as being additional to the generic specification of needs determined at the inception of the project.

Apparatus for centrifuge modelling of twin-tunnel construction

Apparatus for centrifuge modelling of twin-tunnel construction

Twin-tunnel system As well as the obvious need to have two tunnel supporting components a number of other modifications were made to the previously described design. Principally, the outer diameter of the tunnels was changed to 40 mm. This change was to ensure the observed movements were not affected by boundary conditions due to the restricted size of the strong box. Using semi-empirical methods such as those described previously, a settlement trough was predicted for each individual tunnel. Accepting this simplification, even at the maximum proposed centre-to-centre spacing the extent of the settlement troughs were not predicted to reach the side walls of the strong box.

An apparatus for centrifuge modelling of a shaft construction in clay

An apparatus for centrifuge modelling of a shaft construction in clay

Irrespective of the method used, any underground construction project will cause ground movements which have the potential to cause damage to existing structures. Modern geotechnical engineering prac- tice aims to reduce these movements to a minimum but the need for accurate assessments is critical to the success of many projects. For example, BS EN 1997-2:2007 (BSI, 2007) specifies that the location and condition of adjacent underground and surface infrastructure should be determined implying that existing structures should always be considered dur- ing design and construction.

The Design And Development Of Portable Electroless Nickel Plating Apparatus

The Design And Development Of Portable Electroless Nickel Plating Apparatus

2 than lower phosphorus deposits. The basic electroless plating tank construction are commonly made from polypropylene that is natural; stress-relieved polypropylene is well regarded for tank constructions, as it is inert to plating solutions. It easily fabricated for industrial uses and when using proper nitrogen welding techniques, are fairly reliable. Polypropylene-lined electroless nickel tanks have been fabricated in sizes up to 20 feet long and 10 feet wide. However, the life of the welds and of the polypropylene itself are directly related to the strength of nitric acid used in cleaning and stripping the tank, as polypropylene is oxidized by nitric acid, thereby accelerating deterioration.

Construction of an Ohmic Heating Apparatus and Evaluation of Electrical Conductivity of Sweet Lime Juice

Construction of an Ohmic Heating Apparatus and Evaluation of Electrical Conductivity of Sweet Lime Juice

Abstract- Different emerging technologies for thermal food processing were developed and today’s era demands for those technologies which result in high quality with minimum processing. Ohmic heating is the volumetric method of heating in which heat is generated internally within the food mass. This study was aimed to design a laboratory scale ohmic heating system and concluded by evaluating the behaviour of electrical conductivity of sweet lime juice with temperature. Sweet lime juice was heated on static ohmic heater at different voltages in the range of 30-60V and measurements were made at 27 to 85.7ºC after regular 2 min intervals with electrical conductivity range of 1.0933 to 3.760 S/m. Electrical conductivity shows linear relationship with temperature up to certain value of temperature and it is the critical parameter for designing of an ohmic heating apparatus.

WORKING NEAR THE EDGE: A NEW APPROACH TO CONSTRUCTION SAFETY

WORKING NEAR THE EDGE: A NEW APPROACH TO CONSTRUCTION SAFETY

• There appears to be a more powerful theory and approach. A NEW THEORY FOR CONSTRUCTION SAFETY “In a modern dynamic environment where discretionary decision making to a large degree is replacing routine tasks, definition of a correct or normal way of doing things is difficult, and the focus of research should be on understanding of the way in which features of the work environment shape human behavior and the conditions under which normal psychological mechanisms result in unsuccessful performance. The aim in the present context, therefore is not to analyze human errors and to create data bases so as to remove errors by proper work system design but, instead to design work systems that support the actors in coping with the effects of their actions when their performance under particular circumstances turns out to be unsuccessful. In this respect, we have found that a better understanding of the relationship between human adaptation to dynamic environment and human errors is required.” (Page 143, Rasmussen 94)

Design and Fabrication of a Low Cost Field Vane Shear Apparatus

Design and Fabrication of a Low Cost Field Vane Shear Apparatus

A simple cost effective field vane shear test apparatus was designed and fabricated with locally available accessories and materials. This field vane shear test apparatus can be easily used to determine the undrained shear strength of clay soil at shallow depth. Field vane shear test was conducted near Kumargaon at Sylhet city area and the result was found as 49 kPa on average from the field test which indicates the firm to stiff consistency of clay deposition. This type of product could easily be fabricated in the laboratory in a cost effective way following standard method. The academic researchers and the private consultants (construction field) could easily use this type of item for the field strength test of soft, saturated, cohesive clayey soils. However, it will be appreciable if the field value observed by this tool could be compared with some commercial apparatus available in the market conforming the same field condition.

Noise exposure to the workers in Malaysian construction industry

Noise exposure to the workers in Malaysian construction industry

1.3 Statement of Problem In construction, engineers are more concerned on the safety aspect such as deflection or cracking of a building application. For architects, they might more interested on the aesthetics of the building design. Therefore seldom people will notice the importance of acoustic quality in the environment during construction stages especially the noise produced from the construction equipment. Moreover, most of them might think that it is unnecessary to have a good control on the acoustic quality in construction sites.

Analysis, Design and Fabrication of Forced Convection Apparatus

Analysis, Design and Fabrication of Forced Convection Apparatus

The flow in boundary layer starts as smooth and streamlined which is called laminar flow. At some distance from the leading edge, the flow turns chaotic, which is called turbulent and it is characterized by velocity fluctuations and highly disordered motion. The transition from laminar to turbulent flow occurs over some region which is called transition region. The velocity profile in the laminar region is approximately parabolic, and becomes flatter in turbulent flow. The turbulent region can be considered of three region laminarsublayer (where viscous effects are dominant), buffer layer (where both laminar and turbulent effects exist), and turbulent layer. The intense mixing of the fluid in turbulent flow enhances heat and momentum transfer between fluid particles, which in turn increases the friction force and the convection heat transfer coefficient.

A Guide to Lead Exposure in the Construction Industry

A Guide to Lead Exposure in the Construction Industry

Zinc-containing primers covered by an epoxy intermediate coat and polyurethane topcoat are commonly used instead of lead-containing coatings. Mobile hydraulic shears can be substituted for torch cutting under certain circumstances. Surface preparation equipment, such as needle guns with multiple reciprocating needles completely enclosed within an adjustable shroud, can be substituted for abrasive blasting under certain operations. The shroud captures dust and debris at the cutting edge and can be equipped with a HEPA vacuum filtration system with a self-drumming feature. One such com- mercial unit can remove lead-based paint from flat steel and concrete surfaces, outside edges, inside corners, and pipes.
