Consider a W30x99 beam (Fy = 60 ksi) that is simply supported,
30 ft. long, and subjected to a point load
at the midspan. The point service load consists of 60% live load
and 40% dead load. Lateral supports exist
at the ends only. Design code to comply with: 2016 AISC LRFD.
(a) Determine the maximum point service load P for strong-axis
bending assuming Cb = 1.0.
(b) Redetermine the maximum point service load P for strong-axis
bending considering proper Cb value.

Setting:
Since the preliminary estimate and further investigations indicated that Claire's project is feasible, it is now time to move from the initial concept to final design. In order to do so, Claire will need to consult an architect and an engineer. Thankfully, Claire had an old friend, Tony Tect, who owned a local architecture firm and was willing to help. Claire explained her ideas to Tony and he said he would be happy to produce some drawings for Claire within a few weeks.
Meanwhile, Claire asked Bob Builder if he could advise her about the selection of a design engineer. Bob recommended she talk to Angie Neer from Eager Engineers & Partners. The engineering firm was in Charleston, WV, as was Tony’s office. Tony and Angie had completed several projects together before and knew the value of working hand in hand during the design phase.
Two weeks passed before Claire, Tony, and Angie met to discuss Tony's drawings. After Tony presented his design, Claire made some minor suggestions, but in general was very pleased. Angie then commented on the design, which started a discussion that went on for another hour. Claire wasn't initially comfortable, but later she realized that such discussion is necessary in order to increase the constructability of a structure. Thus, it was advantageous to have structural decisions made early in the design phase and not when the building was already under construction.
After the meeting, Tony sat down on his desk and began to incorporate all the changes into the design. Angie returned to her office to get started on the design for the site preparation. Since Tony agreed to arrange the necessary permitting, Claire had the chance to concentrate fully on preparing the marketing information for the project. However, she realized that she needed to know more about construction project delivery. She had no idea what type of Construction Firm she should utilize for this project. She decided to get some advice from the developer, Bob Builder.
Bob replied to her with the following memo:
In construction Claire, you have several options for your delivery strategy, including: Design-Bid-Build (DBB), Design-Build (DB), and Construction Management (CM). DBB is a very common way to deliver a construction project using a traditional organization. DBB calls for a complete design before site work begins and then a single general contractor assumes all the responsibility for constructing the entire project usually on the terms of a lump-sum contract.
This answer did not really help Claire to understand which type of project delivery method would be most appropriate for her situation. Also, the methods of awarding a contract and the type of contract were confusing to Claire, as she has no prior experience being an owner. Before she could consider making a final decision, she needed more information and recommendations. Claire sent Bob an e-mail asking for a more detailed analysis. This is where you come in to help Claire make an informed decision.
Write a professional memo for Claire including the following information:
In addition to the main contract for the entire project, Bob informs you, the intern, that there will definitely be a sub-contract with a specialty contractor for the site-work on the project.
Keep in mind that you like working for Big Builders and you are considering applying for a job at this company once you have your bachelor's degree. Therefore, you want to impress Bob with a professional report.

Crank Ltd
Crank has been in business since the 1920’s and have three locations in the UK. Their Head Office and main manufacturing site is in Leicester. This site makes complex tubular assemblies for defence organisations, oil and gas and transportation. There is a site at Southampton making tubular shafts for golf clubs, and a site in Glasgow manufacturing aerospace Duct assemblies up to 8″ diameter.
The procurement organisation is currently decentralised. At Leicester, there is a Purchasing Manager, whereas at Southampton and Glasgow, each site has a Chief Buyer in charge of small procurement teams. There is a new Chief Executive of Crank who fervently believes that he needs a new approach for the Group in the way procurement is structured. Over the past month, he has, quietly, been obtaining some salient facts.
The more important ones are
• Each site operates as a ‘Profit Centre’ and the Site Director has to deliver a targeted Return on Capital Employed;
• There are no Group purchase contracts;
• Five major purchases account for 61% of total Group expenditure – they are all raw material including different specifications of tubing;
• There are more than 40 suppliers for the five major purchases;
• No formal tendering has taken place, on any site, for more than two years;
• Capital equipment is purchased by the Group Chief Engineer;
• The company has embraced modern logistics practices including JIT and OTIF (On Time In Full);
• There is no savings plan for purchasing;
• The purchasing teams do not liaise.
The Chief Executive intends to consider an alternative purchasing structure that can deliver benefits for the Group and each operational site. On the basis of your knowledge and the salient facts above what advice could you give him?
Tasks
(c) What alternative structures could be considered?
(d) What are the potential obstacles to change?
(e) What business benefits could accrue from a changed purchasing structure?
