Problem Set 4 (Ch. 10 & Lecture) Resource Leveling and Productivity
Your Name Here
Overview:
Final ‘problem sets’ should include a word document (.docx) (12-point font, 1” margins, times new roman) that responds to each individual problem below. Include the problem statement in this document, as well as your solution. Make sure that each solution includes:
A description of what you did and how you did it;
All values clearly labeled with units (e.g., “work days”, “crews”, “workers”);
A reference included for any reference to a table, figure, or equation provided in a text; and
A clear description/reference to what you found;
All calculations (formulas and how they are used) must be shown; and
Calculations can be completed in excel, but must be documented in full professionally in this word document.
Problem #1: The estimate for a three-story dormitory included 30 plumbing fixtures on each of the floors. In developing the bid, the estimator used a production rate of 0.625 person-hours per fixture. The project superintendent is organizing the plumbing crews to include two plumbers per crew. What is the duration (in days) of the activity to install all the fixtures in the dormitory with one crew? Assume an eight-hour workday and round the total days up to the whole day.
Hint: The production rate provided is ‘person-hours per fixture’; you have multiple people per crew working. You will also need to calculate the total quantity of fixtures for the building with multiple floors.
Solution #1:

Problem #2: For each of the following activities and corresponding estimated information, calculate the following information:
Production rate per crew for each activity (units per crew hour)
Time to complete each activity (hours)
Duration of each activity (whole days, rounded up)

Activity PIB Production Rate (units per man-hour) Quantity of material
(units) Workers per crew

I or 45 30, 35, 40 6.250 200 2

Solution #2:

 

Problem #3: Given the following Gantt chart (with resources corresponding to activities):
What is the distribution of resources (workers per day) required for the existing schedule (unleveled)? (the sum of all resources for each day of the project as scheduled)
You determine you have enough workers to higher up to 6 workers per day between the 1st of the month and the 10th, but after that you only have enough workers to hire 5 per day. Does the existing unleveled schedule allow for this constraint to be met while still delivering the project on time? If not, can the schedule be leveled to meet this constraint and deliver the project ton time? If so, produce the leveled schedule and indicate what changed. If not, describe the constraint that prevents both constraints (on-time completion on the 25th and limited workers per day) from being met. For any given day an activity takes place, the workers per day are the required number of workers to complete the activity for that given day—no splitting up crews.
Hint: “IN” represents interfering float. “F” represents free float. The schedule has already been placed into a calendar with additional holidays. Do not schedule workers over the weekend or during the holidays!

Solution #3:

Problem #4: See the resources needed for each activity and the corresponding calendar. Add the resources to your calendar (below). For any given day an activity takes place, the workers per day are the required number of workers to complete the activity for that given day—no splitting workers.
Hint: “IN” represents interfering float. “F” represents free float. The schedule has already been placed into a calendar with additional holidays. Do not schedule workers over the weekend or during the holidays!
Determine what the required resources are in workers per day.
You have a maximum ability to hire 6 workers per day. Can you level the schedule to complete your job on time? If so, what would the “leveled” schedule look like? If not, explain why not and level the schedule to show the new project schedule and duration that accommodates the resource constraints.

Problem #2: Develop a preliminary WBS for a small one-story commercial building to be constructed on the site of an existing small-frame structure. It is 30 by 60 feet in plan (see illustration). The site will need to be prepared (clearing, remove over burden, grade the site). The exterior and interior (partition) walls are of concrete block. The floors are made of concrete, which will first require a carpenter to develop wooden forms, and then topped with asphalt. The roof is constructed of bar joists covered with a steel roof deck, rigid insulation, and built-up roofing. The ceiling is suspended acoustical tile. The floor is a concrete slab on grade with an asphalt tile finish. Interior finish on all walls is paint.
⦁ Include at least two levels of the WBS for this small building.
⦁ Include two short discussions (~200 words) summarizing (1) how you developed the WBS and (2) the issues you ran into while you did it.
⦁ WBS may include either a flowchart or an outline, depending on student’s preference.
⦁ If you are unsure what any of these terms mean, investigate! (i.e., google!)

Identify and describe each element prepared for a typical bid package.

Written Discussion: After reading HSL Ch. 2 Preparing the Bid Package, define the bid process in your own words. Identify and describe each element prepared for a typical bid package. Indicate whether each item is (a) submitted as part of the bid package or (b) developed to inform the bid package but not submitted as part of the bid package. All written or “communication” discussion posts require that you respond to at least two other student’s posts. Responses must provide a contribution to the conversation–such as questioning or introducing how different conditions may change the bid process, as defined by the other student.

develop a graphic, poster, or flow chart that describes the process of construction from the acceptance of the award to the final payment.

Communication: After reading CMF Ch. 2 Overview of the Construction Industry (PDF provided) and HSL Ch 3. Issues During Construction, develop a graphic, poster, or flow chart that describes the process of construction from the acceptance of the award to the final payment. Include a brief description of each stage of the process in your graphic, and indicate which project player is (or may be) responsible for each element. Not every ‘stage’ of construction happens every time–consider including some information that denotes the conditions that may change the process. Use software or a style of communication that makes the most sense to you, but make sure your graphic is legible and easy to follow. Consider adding a legend if you use a lot of symbols. All written or “communication” discussion posts require that you respond to at least two other student’s posts. Responses must provide a contribution to the conversation–such as noting things you missed in your graphic or players the other student may be considering that you may not.
