Q: Given the variety and number of competitions, could you please classify each competition per GLSC Constitution Article III, Section 5D? For example: "Concrete Bags - Engineering event (prior preparation required)" "Service Activity - Voluntary Exhibition Event. No conference points awarded".
A: All events have been labeled according to this suggestion.
Environmental Competition (engineering event, no prior preparation required):
Q: Please confirm each team will pour the same amount of water into their system.
Q: Will teams be allowed to pour the water into their own system?
A: No, the judge will do this.
Q: Please provide costs per unit for the materials listed below. Will teams be provided with these materials at the competition, or can teams arrive with their own materials?
A: Materials will be provided by host university.
Q: How much time is given for the "purchase" of materials and "construction" of the system?
A: Purchase time will be 5 minutes and construction time will be 10 minutes.
Q: What is the size, spacing, and number of holes drilled into each bucket?
A: The holes are about ⅛ inch in diameter. The spacing and number of holes is represented in the image below. The bottom of the bucket is 10.24 inches in diameter. Photo is provided in revised rules. We will be providing the buckets.
Q: After the designated amount of water is poured into the top bucket, after what amount of time will testing conclude and the amount of effluent water and concentration of salts be measured (how long will be allowed for the water to drain out of the bucket)?
A: The water will run through the system for 20 minutes and then be tested.
Q: Please clarify the scoring method and/or provide an example score sheet.
A: A score sheet is provided in rule updates.
Q: How will the concentration of salts be measured?
A:The judges will measure the salt concentration using laboratory equipment.
Geotechnical Competition (engineering event, prior preparation required):
Q: What type of mesh is to be used (plastic, wire, etc.)?
A: You will use a fiberglass door and window screen mesh for home use (no other restrictions).
Q: Do you have specific material brands in mind or an ASTM standard?
A: The brand of the materials does not matter.
Q: Are there any dimensional restrictions to the floodwall? What type of terrain will the floodwall be built on (i.e., wood, plastic, soil base, etc.)
A: The floodwall can be a maximum of 14 inches wide and 16 inches high as pictured in the revised rules on the GLSC website. Placement of the floodwall in the competition space (known as the module in the rules) and depth of the floodwall are at the team’s discretion, but factored into the final score.
Q: Please further define the module. Please provide dimensions, materials it is made of, pictures, etc.
A: Check the revised rules for dimension and material specifications of the modules and a figure for reference.
Q: Please provide a list of designated materials stores. Please verify that we need to provide our own materials for this competition or is this a "fictitious store with monopoly money."
A: All materials for the floodwall and module are purchased by each university before conference. Materials for the floodwall may be purchased from any source before the competition so long as packaging/labels are provided. Each material for the floodwall will have a fictitious cost associated with it used in the determination of the final scoring. Further information about the materials can be found in the revised rules on the GLSC website.
Q: Can teams purchase materials throughout the 90-minute build period?
A: An initial “supply” of materials is determined prior to the competition and additional material may be added to the supply from the “storage area”. Check the revised rules for additional details. It should be noted that the rules have been modified such that all materials to compete in this competition must be purchased by each university prior to conference and brought with them.
Q: Define leakage. Is underflow, overflow, or side flow considered leakage?
A: Leakage is defined as any water penetrating the floodwall in the protected area with the model homes. This leakage can be described as overflow, sideflow or underflow. Once leakage begins to occur, pouring is stopped and you have the choice to repair.
Q: Can you describe how the water will be weighed and how you will differentiate between water retained and water that passed the floodwall?
A: The amount of water entering the module will be measured as the water retained. The amount of water that passes the floodwall into the protected area will be measured and deducted from the total water retained.
Q: What happens if a team chooses not to repair? Will they be scored based upon their current retained water?
A: Yes, you will be scored based upon your current retained water.
Q: What is the cost to repair?
A: To repair, you can only use materials present in your supply at the completion of the 90-minute build time. If you don’t have any extra materials, you can’t repair. There will also be a $50 cost to repair added to your cost score.
Q: Will the modules be drained after the repair?
A: Before the repair, the module can be drained. If your team would like to install a spout-like mechanism in your module, that would be a good way to drain it. All repairs must be completed within 15 minutes.
Q: Verify that "strength" is defined as "pounds of water retained”
A: Strength is represented by the volume of water retained. The scoring rubric only uses volume instead of converting to pounds per unit area.
Q: Please provide the unit cost of each material.
A: Provided in the revised rules on the GLSC website.
Q: Are we required to buy the silt material or can we sieve from other material? If required to buy, what are some retailers that carry silt?
A: You can sieve from other materials.
Q: What are the dimensions of the module to budget how much material is required?
A: The module must be 20” x 14” base and 16” height.
Materials Competition (engineering event, prior preparation required):
Q: The rules state "Judges will be responsible for recording each team’s compressive strength and density. Judges may deduct points as they say fit." Please provide reasoning for why points should be deducted.
A: A score sheet has been added to the .
Q: When and to whom does the data sheet need to be submitted?
A: Please send your submittals to the UIC GLSC email address no later than 11:59 PM CST March 22, 2018.
Q: Define failure.
A: Failure is defined when the cylinder begins to experience fractures or cracks in one of the following ways: vertical cracking, cracking through caps, diagonal fracture, or side fractures. This test will consider failure Types 1 – 6, as a failure. Examples of failure and Types 1-6 failures in testing of compressive strength of cylindrical concrete can be found in ASTM C39/C39M.
Q: Technical data sheet will receive full points, 100 points, when completed as judges see fit.---Provide technical data sheet that must be filled out. AND/OR define what judges will "see fit."
A: See score sheets.
Q: Are team scores compared against each other or is there a maximum of 100 achievable points? If there were a maximum of 100 points to be received, how would a team achieve 100 points? What compressive strength/density would be required? Please define in detail.
A: You will be compared against each other. See the score sheet in revised rules.
Q: What does the 30% density calculation mean? Does is mean you guys will be measuring the density the cylinder the day of competition or am I suppose to calculate it before hand and include the answer with technical data sheet?
A: It will be measured the day of the competition.
Q: Is it required to use at least one of the supplementary cementitious materials such as fly ash, slag, etc.? Or is this just optional?
A: It is optional.
Q: Water to cement content ratio must be a minimum of 0.35. I assume that this is "water to the total cementitious material ratio". Please clarify.
A: Yes, this includes all cementitious materials.
Q: Cement content must not exceed 600 lb./yd3. I assume that this cement content including other supplementary cementitious materials. Please clarify.
A: Yes, this includes all cementitious materials.
Quiz Bowl (engineering event, no prior preparation):
Q: Are team members allowed to discuss while the question is read and after the question is read?
A: You can discuss, but know that another team might figure out the answer first or hear your discussion.
Q: Please confirm that ALL questions are worth one point (with possible exception to the Jeopardy question).
A: All regular questions will be worth 1 point. The first jeopardy question will be worth 2 points and the challenge jeopardy question will be worth 3 points.
Q: Are teams wagering points for the Jeopardy question? If so, how does this process work? If not, is the Jeopardy question also worth one point?
Q: For round 2, are all participating teams starting with the score received in round 1? Or are teams starting at 0 points?
A: Your points from round 1 will not carry over to round 2. The scores after round 2 will determine the first, second and third place winners of quiz bowl.
Transportation (engineering event, prior preparation required):
Q: We noticed that the intersection that we are redesigning has already been updated as of 2017 and we were not sure if we should base our original designs off of the old intersection or the current updated intersection. This is important for determining our economic efficiency with our new model.
A: Base your designs off of the old intersection.
Q: Is there a formal presentation to the judging panel?
Q: Please provide a sample score sheet to show weighted importance of these categories.
A: A sample score sheet is included in the revised rules.
Q: According to the scoring description, required materials (LOS analysis, cost estimate, sample calculations, and other technical items listed in the submittal section) are not taken into account.
A: Submittals will also be taken into account. Reference the score sheet in the revised rules.
Q: Please describe or provide an example of the trip distribution figure required.
A: This would be the output of HCS2000 or other software that your team uses for design. Photo is provided in revised rules.
Concrete Frisbee (engineering event, prior preparation required):

Q: The rules posted on the website differ from the rules included in mailer two. One requires a video; whereas the other requires a trifold. Which rules will be used?
A: The wrong versions were accidentally uploaded to the website and we apologize for the mistake. Go by the revised rules now uploaded.
Q: Do you require specific verbiage on the photo consent form, or is it up to the team's discretion? Are we releasing the photos/ consent of use to UIC ASCE?
A: Specific verbiage is not required, however full consent must be granted with no restrictions. Consent for minors should include a signature of parent or guardian. The photos will be released to ASCE UIC Student Chapter and the Great Lakes Student Conference.
Q: May teams record video at the event and then clip the video to meet the requirements listed here? Is this considered editing? Is this required to be a continuous video?
A: Teams may record the event and provide a clip. This is considered editing. A continuous video is not required. Each portion may be submitted as a clip.
Q: To clarify, teams are uploading individual photos with a one-sentence caption to the Google drive. Teams are also submitting a separate document containing a list of participating members, activity explanation, community impact, the picture captions, and file path for each picture. To confirm, there are no pictures in this document.
A: Correct, this document does not contain photos.
Q: Can you define what is considered "civil engineering related". For example would a STEM expo with engineering principles be considered related?

Concrete Bags (Engineering event, prior preparation required):
Q: Please provide Figure 1.
A: Provided in revised rules.
Q: Please provide Figure 4. Will the board be fully supported underneath or just along the edges?
A: Provided in revised rules.
Q: Does the full name of the university need to be on the board, or can schools use abbreviated titles as approved in Concrete Canoe RFIs?
A: University abbreviations are fine.
Q: How far apart will the boards be?
A: 27 feet.
Q: Will members throw to their own board, or throw to their opponent's board?
A: Half of the team will be standing by their own board and the other half will be standing across by the other team’s board.
Q: Is the scoring for the technical criteria related to the concrete mix an "all or nothing" single score? Please describe in further detail or provide a sample scorecard.
A: See score sheet in revised rules.
Q: Define failure
A: Board failure would be if your board breaks and is unusable.
Q: The aggregate is True Lite and according to its technical specifications (see attached), 95% of it passes through the 1/2 sieve and only 2.4% is retained in the 200 sieve. Since the specific wording in the documentation for the competition is, " Aggregates must pass a 1⁄2 in. (12.7 mm) sieve and be retained on a # 200 sieve," I just wanted to double check before I submitted the mix.
A: This is fine.
Wooden Bridge (engineering event, prior preparation required):
Q: Basswood sticks- Please define
A: Basswood sticks of multiple sizes as members- 24" long, square cross sections: 3/32", 1/8", 5/32", 3/16". Plywood plates, 1/32" thick to be used as connections. You are to choose the stick size needed to optimize the maximum load but not more than it needs to be because then it adds unnecessary weight to bridge.
Q: Are end supports intended to define the ends of the bridge or the ends of the testing apparatus? Are end supports intended to define the ends of the bridge or the ends of the testing apparatus?
A: The end supports refer to the ends of the testing apparatus (tables).
Q: Please provide further description of how the bridge will be load tested. How will weight be loaded to the metal rod? Will the bridge need to include any specific design criteria to accommodate load testing?
A: Weight (sand) will be loaded at the center of the trusses in a plastic pail connected to the bridge by a string/rope.
Q: Define Failure
A: Failure is when the bridge breaks. It will be made of pretty thin wooden sticks.
Q: Judging- Are one of these factors weighted more than the other? How will these be combined? Please provide a sample score sheet.
A: All of those factors will be calculated into the PV. Your actual PV and your previously calculated PV will be compared.
Q: How will the actual and calculated PV values be compared? Will judges calculate the difference between the two or percent error?
A: Percent error.
Q: For clarification, a 24" bridge that is 100 grams (roughly 0.22 lbs.) only supporting 125 lbs. of weight is considered "not very good"
A: Realistically, it will be more like 35-40 grams, but that is really for you to decide. This experiment has been done and a 35-gram bridge was able to carry 75 pounds, which makes a PV of over 2. The point is to optimize the mass of the bridge versus the weight it can carry.
Q: Where are the referenced weight guidelines?
A: There are suggestions in the revised rules.
Scavenger Hunt (non-Engineering Event, no prior preparation required):
Q: Will tasks be worth a different amount of points?
A: If tasks are worth a different amount than others, it will be noted on the Scavenger Hunt list that you will receive on Thursday morning, April 19th.
Q: Please confirm the list will be available on the morning of Thursday, April 19.
A: The list will be made available at the time according to the posted rules.
Q: Will separate events require separate deadlines? Or is there a single deadline for submission of all photos?
A: There is a single deadline for all photos (4:00 PM on Saturday, April 21st). As mentioned, if there is a tie, the final timestamp of all submissions will help identify the winner.
Q: If teams are submitting photos as they complete tasks, how will the time difference between each task be calculated? For example, Team A submits photos for tasks #1, #2, and #3 earlier than Team B. Team B submits photos for tasks #4, #5, and #6 earlier than Team A. How will a winner be determined? Please provide an example score sheet.
A: Timestamp is based on final submission. If teams elect to use their scavenger hunt folder to compile photos at separate times, that will not affect your score.
