3. What are the differences between balloon framing and platform framing? Platform: a) Studs in platform framing extend only from the top of one level of framing to the bottom of the next. b) In platform framing the studs and sole plates rest on the top of the floor platforms. Balloon: a) Studs in balloon framing extend unbroken from the foundation to the roof. b) Firestops are required in balloon framing to close the cavities in the wall against the passage of fire. c) Floor joists in balloon framing rest on a wood ribbon (also called ribband) recessed into the studs. d) Studs n balloon framing rest on the sill. What are the advantages and disadvantages of each? Platform: Advantages: Platform framing is much easier to erect. Size of lumber is standardized and easier to manufacture. Almost no additional fireblocking is required. The walls bear upon the platform rather than directly upon the walls of the story below. House can be one or three stories instead of just two. The platforms are convenient working surfaces for the carpenters who build the frame. Disadvantages: Platform frame settles considerably as the wood dries and shrinks. Balloon: Advantages: 40% cheaper than mortise and tenon frame. Two men could attain the same results in a day that required twenty men using the old-fashioned method. Disadvantages: Lumber lengths are much greater, needing to span from the foundation to the attic. Fireblocking has to be added between floors. Floors rest on ribbands around the perimeter of the structure. Why has platform framing become the method of choice? Balloon frame used full-length studs that ran continuously for two stories from foundation to roof. In time, it became apparent that these were too long to erect efficiently. Furthermore, the tall, hollow spaces between studs acted as multiple chimneys in a fire, spreading the blasé rapidly to the upper floors, unless they were closed off with wood or brick firestops at each floor line. Several modified version of the balloon frame were subsequently developed in an attempt to overcome these difficulties. The most recent of these, the platform frame, is now the universal standard.

4. Why is little added fire stopping required in platform framing? Because each platform is a complete solid surface in the horizontal plane with very few openings between stories, unlike balloon framing where the floors were build against the studs instead of on top of them.

5. Why is a steel beam or glue-laminated wood beam preferred to a solid wood beam at the foundation level? Steel and glulam are stronger than solid wood, shrink less (or not at all), and are straighter.

6. How is a platform frame building braced against wind and earthquake forces? Walls are sheathed with either plywood or OSB, which provide permanent, very stiff bracing, or with diagonal let-in bracing. Also walls are attached to the foundation or floor platform with metal hold-downs to prevent the walls from pulling up off the foundation or floor platform.

7. Light framing of wood is highly combustible. In what different ways does a typical building code take this fact into account? The building code severely reduces the size of building that can be build using light wood construction as compared to other types of less combustible construction.

Chapter 6 Questions, pg 253

3. Which types of siding require a nail-base sheathing? Wood shingles and shakes require a nail-based sheathing material. What are some nail-based sheathing materials? OSB or plywood. Name some sheathing materials that cannot function as nail bases. Insulated sheathing materials.

5. How does one make corners when siding a building with wood shingles? Two methods of making corners with wood shingles are weaving where the first walls shingle extends to cover the second walls shingle edge and then alternate this up the wall. The second method is to cover the corner with a corner board.

6. Specify two alternative exterior coating systems for a building clad in wood bevel siding. Aluminum and vinyl sidings are both intended to imitate wood horizontal bevel sidings.

7. What are the usual reasons for premature paint failure on a wood-sided house? No aspect of painting and finishing work is more important than surface preparation. Unless the substrate is clean, dry, smooth, and sound, no paint or clear coating will perform satisfactorily.

Construction projects are generally considered as a transient disturbance, where the construction works happen rather a short period of time. But, from another point of view, construction project is a long-lasting feature of economy. So, in order to make a construction project to be positively presence, the time management techniques are ought to be investigated. Of course, there is not all time management techniques are productively to every stage of construction project. It can be involved of knowledge of planning a timely procurement method to be use during pre-construction stage, controlling the schedule to maintain ahead of work progress during construction stage or analysis the project status in the post construction stage. It is depends on the person who organize the time management methods, and it is only resulted as success when the project is completed within an approved timeframe. During construction stage, a successful time management is explicitly a factor of the execution of job (Barling et al., 1996; Macan, 1994). It is a skill that can be learned which involves techniques for prioritizing activities and using time effectively while eliminating disruptions and time wasters.

Risks in a Home Building Project

...Score 6% A Review of Risks Associated With Estimating a Home Building Project Introduction In building and construction, there are risks associated with estimating a home building project. These risks in construction are all the same across the board regardless the construction. Therefore, a home building projects is confronted with the same risks as any other project in the construction industry. The risks involved are such as; project management risks. The project management risks are mainly because of improper schedule. The improper schedule may be caused by poor allocation of time in various projects that may be involved in a home building project. Poor resource planning is another management risk. This is because due to poor allocation of resources often lead to misuse and many unaccounted losses. In addition, improper and poor management of disciplines or methodologies result into management risks in a home building project. Disciplines and methodologies are tricky and need a lot of experience to manage. Therefore, a minor mistake in management of discipline and methodology is a risk that can cause a huge negative impact in a home building project. Such risks are better identified with scheduled risks. Organizational risk is a major risk that most building and construction projects have to face, Most organizational risks in home building projects results from issues such as; resource conflicts.

Industrialised Building System

...the adoption of construction industry and the use of prefabrication of components in building construction. IBS is defined as a construction technique in which components are manufactured in a controlled environment (on or off site), transported, positioned and assembled into a structure with minimal additional site work [1-4]. It consists of precast component systems, fabricated steel structures, innovative mould systems, modular block systems and prefabricated timber structures as construction components [3]. Parts of the building that are repetitive but difficult and too time consuming and labor intensive to be casted onsite – are designed and detailed as standardized components at the factory and are then brought to the site to be assembled [3]. The onsite casting activities in IBS utilize innovative and clean mould technologies [1-3]. The construction industry has started to embrace IBS as a method of attaining better construction quality and productivity, reducing risks related to occupational safety and health, alleviating issues for skilled workers and dependency on manual foreign labor, and achieving the ultimate goal of reducing the overall cost of construction. Apart from this, it offers minimal wastage, fewer site materials, a cleaner and neater environment, controlled quality, and lower total construction costs [4-6]. ...

Project Managent

...Maintaining steady completion of construction projects, has until recently, been an issue of serious concern both to the client and contractors. Standish Group Report (2007) noted that mega projects fail at a higher rate than small/medium sized projects. According to Khatak(2009), the main reasons and causes of project/task failure are embodied in four key dimensions of the task, namely –time, cost, quality and content. The end users and stakeholders of a project also play a fundamentally important role towards success or failure. Lock (2007), asserts that consequences of failure of projects can be multi-dimensional, having far reaching effects on individuals, communities and organizations. In more visible terms time and cost overruns are common features of failure of projects, resulting in delay of service or product delivery. Kappelman et al., (2006) says that the high rate of failed/incomplete or abandoned projects negatively impacts government/organizational performance, costing tax payer billions of money in losses. In quantifiable terms the cost of delays and partial or inadequate accrual of the envisaged benefits in the shape of increase in revenues, improvements in service, quality or technology would vary according to the nature and scope of project. In developing countries like Kenya, projects are the life line of construction plan or programs. Failure of...

...The RELIABLE CONSTRUCTION COMPANY has just made the winning bid of $5.4 million to construct a new plant for a major manufacturer. The manufacturer needs the plant to go into operation within a year. Therefore, the contract includes the following provisions: • A penalty of $300,000 if Reliable has not completed construction by the deadline 47 weeks from now. • To provide additional incentive for speedy construction, a bonus of $150,000 will be paid to Reliable if the plant is completed within 40 weeks. Reliable is assigning its best construction manager, David Perty, to this project to help ensure that it stays on schedule. He looks forward to the challenge of bringing the project in on schedule, and perhaps even finishing early. However, since he is doubtful that it will be feasible to finish within 40 weeks without incurring excessive costs, he has decided to focus his initial planning on meeting the deadline of 47 weeks. Mr. Perty will need to arrange for a number of crews to perform the various construction activities at different times. Table 10.1 shows his list of the various activities. The third column provides important additional information for coordinating the scheduling of the crews. For any given activity, its immediate predecessors (as given in the third column of Table 10.1) are those activities that must be completed by no later than the starting time of the given activity.

...by anyone who is designing buildings in the same way GIS was embraced by other people, in addition to his statements; he feels that cities should be planned more efficiently. “This whole idea of being sustainable applies to the greater context as well — not just a specific project, but in terms of how that project relates to other projects, and how one city relates to another city, and how that road relates to the city. So, I believe in BIM.” Schlosser (2012). BIM, also known as Building Information Modelling, has many successes which include improved design processes, coordinated construction has become more efficient, and documentation has become streamlined, detailed 3d models, analysing and modelling is often performed within those specific tools. Construction is now moving at a faster pace due to the BIM streamlined architecture and infrastructure projects, along with the faster construction, there are less change orders and delays and the project costs can now be...

We use data collected during interviews with contractors and data from questionnaire surveys. Results show that contractors do understand the potential benefits of quality implementation but that there are also many barriers to implementation. We describe recent developments that might help to overcome the barriers. However, the different actors in construction need to understand that change is a slow and often painful process and that much effort is required to implement quality in construction industry.

Procurement

...EFFECT OF PROCUREMENT SYSTEMS ON THE PERFORMANCE OF CONSTRUCTION PROJECTS Abstract: Project procurement has been described as an organized methods or process and procedure for clients to obtain or acquire construction products. Apart from the traditional approach, there are now other “fast-tracking” or innovative procurement systems used by the construction industry world wide. The different procurement systems differ from each other in term of allocation of responsibilities, activities sequencing, process and procedure and organizational approach in project delivery. These differences have invariably affected the project performance. Project performance has been defined as “the degree of achievement of certain effort or undertaking” which relates to the prescribed goals or objectives that form the project parameters. There are many other elements that determine project success, but the focus of this paper is on the three critical parameters or project performance i.e. time, cost and quality. The aim of this paper is to look into the effect of the different procurement systems on the project performance. Since there are many different project procurement systems, it is appropriate for the purpose of this presentation to limit to the common ones i.e. traditional system, design and build and management contracting. Keyword: Project procurement, performance, time, cost and quality INTRODUCTION The procurement of construction project is vast in scope because it involves the gathering...

...1000e106 Open Access Managing Multicultural Construction Teams in today’s Complex Global Environment Edward Ochieng* Faculty of Technology and Environment, Liverpool John Moores University, Liverpool, L3 3AF, UK The rapid globalisation of the world’s economy has had significant impact on the way construction project managers work, bringing them frequently with clients, suppliers and peer that they never work before. In an era of globalisation, projects in the construction industry face unique challenges in coordinating among clients, financiers, developers, designers and contractors from different countries. In addition, construction project teams need to cope with the complexities of both local institutions and physical environments. Bartlett and Gosha [1] discussed the challenges facing organisations, which are intending to work effectively across borders. They identified the major challenges as being able to develop practices, which balance global competitiveness, multinational flexibility and the building of a worldwide learning capability. They maintained that achieving this balance will require organisations to develop the cultural sensitivity and ability to manage and leverage learning to build future capabilities. While offering opportunities, globalisation also poses significant challenges for construction project managers especially when different cultures are involved as a team. Multicultural construction project teams have their culture as a set of shared...
