Marvin Townsend City Manager P. O. Sou 9277 Corpus. Christi. Tema Res Holly Road Ground Storage Tanks Dear Mr. Townsends This morning we wade an inspection of the Holly Road ground storage tanks with Atlae Cunningham, to observe the damage done to the tanks I by Hurricane Colia on august 3. we entered both taanks, using a Oubbsr raft, and examined the roof structure* moth tanks were found to have suffered damage. The roofs of the tanks are steal plate, lapped and welded on the top side only, laid on steel channel purlins which span from the outer wall to interior steel beams supported by columns. The roof sides is not welded to the purlins. because of stresses which would result from such restraint, and because providing steel weight for such increased stresses (plus the increased welding cost) which have increased the initial cost greatly. The purlius are supported by welded brackets and bolts on the tank wall and on the interior beams. The damage observed was primarily to the purlin channels. Many were found to be bowed latierally, and many were also tilted over at an angle. On the south tank, this was so extreme as to cause a water - holdingg depression in the roof. We believe the purlin failures were caused by end -wise stresses induced by the yielding of the tank walls with the great wind presoures involved, plus the extremo hammering effect the roof skin must have given the purline during the wind gusts. Slight out -of- straightness would thus have been exaggerated into a 'definite bow. L Page 2 Mr. R. Marvin Townsend August 19, 1970 The purlin channels do not have a very groat lateral 600ft e990 and to believe goat, with a fewr eptlons. they can be straightened without permanent d —agae. Their performance in service shows that it will bo dosirable to provide some sort of lateral stiffening to all of the purline, with possibly some extra attention to the straightened ones. This work would be beyond the capacity of your maintenance staff, and should be Contracted. We cannot. give a construction cost estivate until the damage is studied more quantitatively sad a plan io agreed upon. We propose to the City that we undertake the preparation of platys said specifications for this work. We will m2a1ce additional detailed survey® In the twuka. to fully define the contractor's work quantltlee, determino the most cuitable memo of repair, prepare 1Uma and apacifications, aesist in receiving bids and awarding the eontrac% and provide the core. tract a e—in9 stration during the construction phase, generally in ascordmnce with the terms of the Tawas Society of Professional Engineers Manual of Profession -1 Practice, 1967. for a Lamp Slants roe of $2,900. We will, if desired by the City, iurnish a construction inspector at salary coat times a factor of 2. 0. plus 131 a mils for transportation, plus. other direct coots times 1. 15. We do net believe full time inspection wM be necessary but cannot at this time offer an estimate of this cost. If lists proposal to satisfactory, we would consider eadornament, of tbis letter as an adequate agreement, and wM be prepared to start work soon der we are notMed.
