The purpose of the change order is to extend the new water line along Williams Street so that it connects with a line at Gilchrist, thus allowing greater water flow on the campus in the event of a fire . I have discussed the issue with my staff and with the Fire Marshall 's office . I will try to summarize their comments . The insurance rates for all cities in Texas are set by the State Board oflnsurance which uses a Key Rate Schedule as a grading system . This Key Rate Schedule sets forth performance guidelines for fire hydrants and the water mains that serve them. I have copied a page from that schedule and attached it to this letter. It is our opinion that a school campus falls into the category of "Light mercantile areas" which has a fire flow requirement of 1500 gallons per minute . It does not state how many fire hydrants are necessary, only that the supply line must be capable of carrying this vo lume of water. In discussing this matter with the District's engineer, we indicated that at least two hydrants and the new building's sprinkler system would likely be used to suppress the fire . However, even if a single truck responds and connects to one hydrant, it would be capable of pumping up to 1250 gallons per minute. The requirement we set was not based on the number of hydrants that were flowing simultaneously, only on the volume of water the line could supply. The District's engineer, Mr. David May, then made the d~termination th 'it the line he had designed could not carry the required flows . In Mr. Neal's memo he also states that he is "confident that this cost would not normally have been anticipated by TPM, Patterson, or Cheatham". This implies that we are holding CSISD to a higher standard for development than is normally found in other cities . That is simply not true: The guidelines we followed in this case are the same everywhere in the state and should have been anticipated . I regret that Mr. Neal was given this information, and would like to discuss what Mr. May's experience in other cities has been . Home of Texas A&M University In Mr. Neal's last comment he states that the City has not yet given its approval on these plans. I have visited with my staff and we have gotten that situation rectified . The utility plans referred to in the letter have been approved and the District can move forward as necessary. I apologize if this issue has caused problems with the ?~mstruction schedule for the College Hills campus . However, our driving motivation is simply to insure that our Fire Department has the ability to suppress any fires on the campus that should occur. If you or your staff have questions regarding our actions or decisions in this case, please contact me or any of my staff members .

JVt Inv cf---___ SUBJECT: o. 1 -Diamond C01zstruction Company -College Hills AGENDA ITEM -E.l , We have previously advised the Facilities Committee of a change order that would be fonhcoming regarding the College Hills' project. Over the last few months, Bill Savage, and David Mays (Cheatham Engineering), have been reviewing the fire protection requirements for College Hills. The City has interpreted the code requirement such that CSISD would be reguired to maintain a 600 gallon per minute flow from two (2) fire hydrants operating simultaneously. The only way this can possibly be accomplished is to extend the 8" water main along Williams Street in front of the school all the way from Francis to Gilchrist. This is an additional 576' which will also require boring under Gilchrist. The City has still not approved the plan, and we cannot be sure of the final cost. We have a price of $33, 061 based on what we believe to be the requirement. ( ~fr ,·" J~ I, .-We do not believe the final cost will be significantly higher than this estimq.te. Based on Mr. May's comment that he had never experienced having to meet flow requirements for two hydrants simultaneously, even/or a high school, I am colljident that this cost would not normally have been anticipated by TPM, Patterson, or Cheatham. The city official, Mr. Steve Homeyer, told me that the City's position was based on the fact that the campus was spread out over the property into several buildings, there was a "dead-end", i.e. water could come into the campus from only one direction, and that they had to anticipate a worst case scenario. Mr. Savage has indicated to me that time is very much of the essence. We still have yet to receive City approval, so when we get it, we need to move quickly if we intend to be able to occupy the new classroom addition. We request authority to proceed when the final price is determined. Thank you. 1812 Welsh Street College Station, TX 77840 409-764-5455 FAX 409-764-5492 06 /26 /97 THU 13:21 FAX 409 776 2180 DIAMO~"D CONSTRUCTION DIAMOND CONSTRUCTION, INC. 1606-B SOUTH STATE HIGHWAY 6 BRYAN, TEXAS 77802-1710 (409) 776-2050 (409) 776-2180 (FAX) June 26, 1997 Mr. W .

I have discussed the issue with my staff members and with Jon Mies. I will try to summarize their comments. CSISD's engineer that developed the site plan for the campus expansion showed three fire hydrants in addition to the one that was already there. All four of these hydrants and the 4" line to the new building's sprinkler system are on the 8" dead end line that Mr. Neal refers to. The city's fire trucks operate at flowrates up to 1250 gallons per minute . Therefore, whether one truck is pumping at 1250 gallons per minute or two trucks are pumping at 600 gallons per minute, the demand on the water line is about the same. Without a "looped" water line that allows feed from both directions, the long 8" line is not sufficient to provide enough water to the fire fighting equipment. I disagree with the statement Mr . Neal makes that " the additional cost would not normally have been anticipated by TPM, Patterson, or Cheatham". This implies that we are holding this particular development to a higher standard than others are held to. Whether their engineers model one or two fire hydrants operating simultaneously, it is the volume of water they should be considering and not the number of hydrants. They should have recognized that the amount of water for fire fighting equipment and the building's sprinkler system could not come from an 8" dead-end line. As to the City's approval of the plans, we have received multiple sets of plans from the district's engineer. In each case, portions of the plans were correct and usable, and other portions were in the process of being changed. We asked that a complete set of correct drawings be submitted before approval. Those have just been received and we have approved them for construction. e?JbfJ~ -rd)L XTl-::::!- OLS<Z.. -fa/L_ 3!"Gf/d . 77tr.:) QL ?33-.:::J 133-::f UJV9W~ 2Q SJVOl.LS~YJ?::) AN\/ 3o'(jf-f nOA ::ii .

Conceptual Approach: In order to have a conservative approach to determining the 100 year frequency water surface elevation at the school site, the drainage area was extended downstream somewhat to the confluence of two tributaries. At this point, the Q100 was determined to be approximately 800 CFS. Field Surveys were conducted to obtain accurate cross sections of the waterway behind the school. The 800 CFS was placed in the cross sections to determine the water surface elevations and the spread of the water during the 100 year event. II. Conclusions: The data obtained, based on the approach noted , indicates the water surface to be well below the existing finished and proposed finished floor elevations noted on the drainage area map. We feel the water surface will be substantially below the floor elevations noted and will be in the vicinity of 296.00. In studying the contour maps , it becomes apparent that a storm, even exceeding the water surface elevation we have computed, would have caused major flooding of the homes to the immediate northeast of this project. We are aware of no such flooding in this area. We feel the existing water way will contain the 100 year storm event. III.
