C it Jack: Following our discussion on 7 November, we have considered the possibility of assisting the City with certain aspects of the design and construction of the proposed Rolling Hills elevated tank, instead of performing all design work and supervision of construction. It is the intention to eventually construct the elevated tank, a booster pump station, and a 3-million-gallon ground level reservoir on the land presently owned by the City. A topographical survey has been made and a plan prepared by your staff. There is a possibility that tl,e pumps could be housed within the central pillar of a pedestal type tank, but a preliminary layout of the facilities should be made assuming a separate pump station. The elevated tank should complement the maximum water surface of the nearby Water District tank in case the two systems are combined at some future date. With the height of the tank fixed, hydraulic computations can be made to check the pump performance required by referring to water use projections we have previously made for the area. The possibility of using one or both of the existing Tiffany Park pumps should he reviewed, and all these matters have a bearing on the capacity of the elevated tank. We recommend and assume that a standby engine will be provided in the pump station to guard against a com- olete power failure because the area supplied from the tank will have no other source of supply. It is necessary to perform a soils investigation before designing the elevated tank and foundations, and a local testing laboratory with the necessary drilling equipment would be called in and the results evaluated to determine lesion criteria. We would suggest alternate bids be taken on a standard elevated tank and one of a more pleasing appearance such as the pillar type that is provided by more than one manufacturer. Mr. Jack Wilson City Engineer City of Renton 4 December 1968 Page -2- Special specifications relating to the tanks and to the painting systems are necessary and must be carefully written. Our recent experierce has been that evaluation of bids is becoming more complex due to new construction procedures and consideration of alternate paint systems and their application. Field inspection of painting is essential and its importan:e cannot be over- emphasized. It is our normal practice to furnish complete contract documents, including legal portions in addition to the special specifications and drawings. However, we can provide only the special specifications and drawings for the City to make up the complete contract documents for obtaining bids and executing a contract with the successful bidder. After award of the contract, shop drawings are required for approval as conforming to local codes, including that for earthquake resistance. We would anticipate approving the shor lrawings, but that the City conduct all written and other communications wit ;he contractor. Our part in supervision of construction could be limlte, to instructing your personnel or could extend to whatever degree you desire. It would, however, be necessary to have a clear understanding as to the division of responsibility to fairness to the contractor And all others concerned. On the basis discussed above, we would estimate the extent of our work to be as follows! I. Prepare preliminary sketch layout of all future facilities at reservoir site, including elevated tank, 3-million-gallon reservoir, booster pump station, and Piping. 2. Determine height of elevated tan' , review future water use it elevated tank and ground level reservoir areas; review characteristics of existing ; Iffany Park Ooo!ter pumps; and determine capacity of proposed elevated tank. 3. Vrite brief report describing conclusions reached in 1 and 2 above; reproduce in six (6) copies. 4. Advise the City in engagement of testing laboratory for soils investi- gation; supervise field work; analyze and report on soil samples. 5. Prepare special specifications, drawings, and form of proposal for two alternate types of elevated tank; reproduce in fifty (50) copies. 6. Estimate cost of construction; analyze bids received by the City and recommend award. 7. Review shop drawings and return to City with comments. Mr.ak Wilson City Engineer City of Renton 4 December 1%8 Page -3- 8. Atxend initial site meeting with foundation and piping subcontractor or general contractor and assis. City in scheduling supervision of construction. 9. Advise City on application of paint system and instinct City personnel or inspectior procedures. The estimated cost of the above services, on the same basis that we provide miscellaneous services, is as follows: Item No. M&n/Days Estimated Cost 1 Froject Engineer 1 at $108 $ 108 2 Project Engineer 1 at $108 108 3 Project Engineer 1 at $108 108 Typing 6 Reproduction 100 4 Project Engineer 2-1/2 at $106 270 Techrician 2 at $ 84 166 Laboratory Tests (C42M) 100 Milcage (2 trips) 8 5 Project Engineer 10 at $108 1108C Draftsman 5 at S 84 420 Typist 3 at $ 40 144 Reproduction 400 General Project Manager 2 at $140 _ 280 Subtotal $3,134 6 Prciect Engineer 2 at $106 $ 216 Typist 112 at $ 48 24 7 Prciect Engineer 5 at $108 540 8 Project Engineer 1 at $108 108 Mileage (1 trip) 4 9 Project Engineer 4 at $108 432 Mileage (2 trips) 8 General Project Manager 1 at S140 140 Subtotal $1,472 TOTAL ESTIMATED ENJINEERING SERVICES $4,606 We oelieve the above is a reasonable estimate of the minimum engineerino services which we should provide in the event you decide to arrange the work as described above, We suqgest some further allowance should be made to cover contingencies and estimate the total cost of our services should not exceed $6,D00. We could also perform all design and supervision on a payroll plus expenses basis with $8,n00 as an estimated maximum. • ck Wilson C yJa,"gineer City of Renton 4 December 1968 Page -4- You may wish that we provide engineering services as for previous work on which we performed all design and preparation of contract documents for a fixed lump sum fee, and supervised construction en a payroll plus experses basis. In this event, we would propose a lump sin fee of S8,000.00 to perform Items 1 through 3 and 5 to the expanded degree for all design ano preparation of contract documents. The cost of Item 4, including the outside services, would be additional and is estimated at $1,000. Items 5 through 9 for the contract award and supervision of construction phases would then cost approxi- mately the same as shown, assuming the City personnel performed as much inspection as possible. In this regard, we should point out that an inspector must be prepared to fully inspect the internal and external paint system of the tank bowl ail painting of the tank supports. Not all personnel can work at the necessary heioht above the nrcurd. If you are able to authorize the work to proceed in the near future on any of the three bases described, the tank could be fabricated in the next few months and painted on site under the most favorable weather conditinns with regard to temperature and rainfall. We would be able to start work within three weeks of your order to proceed. We will be happy to discuss any part of this letter at your convenience.

The lump sum design fee of $8,000.00 quoted on the last page of the letter was computed from he 1967 W Curve of ASCE Manual No. 45, which is a guide for the engagement of engineering services. On an estimated construction cost of $110,100.00 the total design and supervision of construe ' ,n fee would be 7.5% of $170,000.00 or $12,700. Design was estimated dt 63� .rr $8,000. and supervision at 371 or $4.700. In this particular instance additional prelim- inary work 'Is included prior to actual design so 'hat the design fee perhaps should have been higher. The ASCE curves of course indicate median fees with a range either side. We feel that the $8,000 fee on the above basis is reasonable. It is understood that you are now considering the proposal at the bottom of page 3 of our letter that we perform all design and supervision on the payroll plus expenses basis that has previously been employed for miscellaneous services. Our estimated fee for design and supervision was $8,000 and this still holds good. However, we should point out that this does not include continuous site inspection during the critical painting operation which would normally be classed as resident inspection. This inspection of prepared metal surface and paint thickness is essential and will have to be provided either by a City-appointed inspector or by a member of our staff. It is not included under the occasional visits covered by supervision. We estimate painting to extend over a three-week period. Mr. Jack Wilson City of Renton 2 January 1969 Page -2- It is our belief that providing a reputable tank ,manufacturing firm such as Pittsburgh-Desl•Wines, Chicago Bridqe and Iron, or American Pipe erect the tank the estimated fee of $8,000 for design and supervision is reasonable based on our past experiencL. We would no: exceed it without your prior approval. If you are in agreement with this proposal, we would draft a proposed contract as soon as possible for your approval and execution. We will be pleased to clarify any further questions you may have. Respectfully submitted, CORNELL. HOWLAND, HAYES & MERRYFIELD 1. • .., Antony B.

We have looked over the proposal and it is approved by us as to legal form only. ,As previ.ocsly indicated, you will have to judge upon the matters of technical work to be done by the Engineers and the rate of compensation fixed in the proposed Agreement. However, we would like to call your atter.tion to some items which you may want to reconsider and insert. A. You may want some provision that in case the maximum estimate of $4,000.00 is ^xce^.ded, that prior written notice would be given to the City so as to assure the City that no additional expenditures would be incurred without its approval. B. Possibly Article 4 B could be amended so as tolimit it by the maximum of $4,000.00 as set forth. C.

Very trul} yours, CORNELL, HOWLAND, HAYES k MERRYFIELD Michael F. Hamilton MEH/uw Enclosure: Contract Documents (Copy No. 54) cc: Mr. Jack Wilson' 1 PROPOSED WATER SYSTEM FACILITIES ROLLING HILLS PUTHORIZATION The work recorded herein was authorized under Contract CAG 1432-69, dated 7 February 1969, between the City of Renton and the writers. PURPOSE The purpose of the report was to layout and describe the immediate and future facilities at the Rolling Hills site and to recommend criteria for elevated and ground level storage. The possibility of transferring the two existing vertical turbine can booster pumps, presently located adjacent to the large Seattle trunk pipelines, to the future pump station at the base of the elevated tank was to be investigated. PREVIOUS INVESTIGATION The writers' report on the Renton water system dated October 1965 has been refe-red to in this investigation. FUTURL PRESSURE ZONES IN POLLING HILLS AREA It is the intention to supply all the Rolling Hills, Tiffany Park, Renton Hill and Talbot Hill areas from City of Renton supply sources instead of continuing to distrib; te water purchased from the City of Seattlr . _T_ The future basic facilities will be: Talbot Grou..I Level Storage Talbot Pump ftation to Rolling Hills 16-inch Pipeline - Talbot to Rolling Hills Rolling Hills Ground Level Storage Rolling Hills Elevated Tank Rolling Hills Pump Station - ground storage to elevated tank Distribution Mains and Pressure Reducing Valves These facilities are shown on Figure 1 with the following future pressure zones: Elevated Tank (MZ 590) Elevated Tank Reduced Rolling Hills Reservoir (MWS 490) Rolling Hills Reservoir Reduced The range of ground elevations each zone will supply is shown on Figure 1. MAXIMUM DAY SYSTEM DEMANDS Reference to Appendices 4 and 5 of the writers' 1965 report on the Renton water system gives the basis for computing system demands. In a developing area such as Rolling Hills and Tiffany Park, the maximum day demand is computed on either an area basis or a population basis. The criteria for the area basis is a rate of 100 gallons per day per 1,000 square feet of total area, with a reduction of 30' for paved areas. In the particular areas under consideration a further reduction of 5% has been applied because of power line easements, Seattle pipeline casements, open space and land which is too steep to develop. -y. Far the population basis a density of 8 persons per gross acre is assumed, with a maximum day consumption of 350 gallons per capita. it is appreciated that much of the area is being developed as high density apartment dwellings, but the maximum day water demand will be approximately the same as on a single family area basis because the latter includes water for garden sprinkling which is not sn great a factor in apartment developnents. PRESSURE ZONES The area under review is supplied from the Rolling Hills elevated tank or the ground level reservoir, and the pressure reduced zones which are supplied from each. There are therefore only two basic zones to consider. The total area served by both the tank and the reservoir is computed to require for the maximum day when fully developed: Area basis 3.70 million gallons Population basis 3.50 million gallons All this water must be pumped at Talbot through the lu-inch pipeline to Rolling Hills ground level reservoir where a proportion is repumped to the elevated tank. TALBOT PUMP STATION - MAXIMUM DAY DEKAND These pumps must provide for the above maximum day demand, and it is preferable to assume a 16-huur operation rather than 24-hour to give some reserve. Total capacity n quired 3.900 gpm (16-hour) Average day will be 50% or 1,950 gpm (16-hour) -3- • Three pumps are recommended with provision for a fourth at a future date. Recommended capacities arc 1,000 gpm; 1,500 gpm; 1,750 gpm; for a total of 4,250 gpm, or 6 ragd if all are running. The 16-inch pipeline would take th,, flow and have capability for more if necessary. This pump selection will give flexibility and stand-by in event of mechanical failure and meet the range of system demand experienced from the winter lou to summer high. No consider+.tion is given here to the pumps necessary for the area immediately surrounding and to the south of Talbot reservoirs which will require addiJ onal pumps and mai,.s. i To this point fire requirements have not been considered. STORAGE REQUIREI'TNTS Reservoir storage is normally based upon the sum of three requirements: a. Operating storage necessary to make up the difference between the peak demand, usually occurring between 6:00 a.m. and 10:00 p.m., and the 24-hour supply capability; b. Water rr ;uired to fight a major fire; and C. Storage sufficient to meet the average daily demand during an outage of the largest single supply source (worst major breakdown). OPERATING STORAGE This is the depletion of storage to be expected during the period of greatest demand on the maximum day. It will be dependent upon pumping capacity and setting of the supervisory controls selecting the pumps. -4- FiRE STORAGE The Rolling Hills ground level reservoir area will contain 4,20o persons when fully built up and the Rating Bureau requirereent for this population is 2,250 gpm for 9 hours or 1.20 million gallons. The elevated tank area will contain 5,WO persons with a fire fighting requirement of 2,500 gpm for 9 hours or 1.35 million gallons. It should be realized that it is nut always economically feasible to provide the storage capacity indicated by Rating Bureau standards. WORST MAJOR BREAM14N For the gound level area the worst major breakdown would be a failure of the 16-inch rain from Talbot pump station to Rolling Hills. It is assumed that this could be repaired within twenty-four hours and storage at Rolling Hills would have to be sufficient to meet the average day demand for both the reservoir and the tank areas or 1.85 million gallons, For th tank area alone failure of the pumps to the tank would be 'ne worst Major brea'.down. Two pwnps are recoinended, of capacities detenninid below, with a staniby driver on the larger in the event of an electrical parer outage. A mechanical failure of the larger pump would leave the smaller in service. CAPACITY OF ROLL P;G HILLS OROMD LEVEL RESERVOIR The capacity of this reservoir should have regard to the following: Operating - ground level reservoir say 0.40 mg - elevated tank say 0.05 mg Total average day demand IAA mg Fire in elevated tank area 1;35 mg (reservoir area is less at 1.20 ng) TOTAL STORAGE 3.65 mg -'S- The ground level reservoir and elevated tank will both contribute to this "ideal" capacity. ROLLING HILLS PUMP STATION The maximum day demand in the elevated tank area is ccxnputed to be 2.16 mg. For a 16-hour operation pump capacity will be 2,250 gpm and the average day would require 1,125 gpm for 16-hour operation. It is recommended that two pumps be installed with provision for a third, and tkat the larger have a standby engine for use in the event of electrical power failure. Subject to reviewing fire fighting requirements, the pumps would be 7,000 gpm and 1,500 gpm respec'ively. FIRE STORM With a population of 5,800 persons iu the elevated tank area fire flm� of 2,500 gpm for 9 hours or a total volume of 1.35 mg is required. By normal standards operating storage of, say, 0.05 mg and average day dema.! d of 1.08 mg is also required for a total of 2.48 mg, It is not economically feasible to provide thi; volume of elevated storage. ELEVATED IV' CAPACITY Assuming an elevated tank capacity of 300,000 gallons with two pumps at 2,500 gpm total and no breakdown, the total volume of water available over a 9-hour period would be 1.65 mg with no storage remaining. Storage of 300,000 gallons represents a flow of 2,500 gpm for two hours, and this should ", sufficient to fight a major fire in apartment blocks or houses in tb- sated tank area. -6- Even with the smaller pump out of service due to an electric power failure, the larger would provide over 1,500 gpm at the lower head against which it would operate. This pump would have to be manually started because a fully automatic ,system is believed not justified. The average 24-hour rate of demand for the average day in the elevated tank area is 750 gpm so additional water would be available for fire fighting beyond the volume stored in the tank. It is recummended that tha elevated tank be 300,000 gallons capacity. SLOMRY The following recommendations are made: Talbot Pumps to Rolling Hills One each at 1,000 gpm; 1,500 gpm; 1,750 gpm. Capacity of fourth pump to be determined when needed. Ground Level Reservoir at Rolling Hills Capacity 3 million gallons. Layout for second of same capacity. Rolling Hills Pumps to Elevated Tank One each at 1,000 gpm; 1,500 gpm. Capacity of third pump to be determined whet needed. Elevated Tank Capacity 300,000 gallons. Height to complement existing Water District tank. Layout for second tank of same capacity. EXISTING TIFFANY PARK PU14PS The Tiffany Park pump station was provided by the developer in 1963 and was taken over by the City of Renton. The two pumps presently take water from the City of Seattle Cedar River pipelines and boost it to a closed system. The smaller pump runs continuously and the larger comes in on low discharge pressure and cuts out en low flow. It is oelieved that two impellers were taken off the smaller pump and the equipment now consists of: One 5-stage, 12 AC, 1,160 rpm pump with 25 hp electric motor One 4-stage, 14 AC, 1,175 rpm pump with 40 hp electric motor The performance curves of both pumps are on file, but the one for the smaller must be interpolated to allow for removal of two impellers. The nominal duty of the smaller is 350 gpm and the larger 700 gpm. A field test was attempted on 23 `larch 19G9, but a malfunction of the control equipment did not allow correct data to be uutained. The highest pressure in the Seattle pipelines is about 41 psi at pump station elevation of about 400. This pressure was recorded at 1:00 p.m. in cold, dry wea_her and lower pressure can be expected in sunmer. It is believed that the aydraulic level in the Seattle lines cannot drop below 455 or there would be no pressure in the lines over the highest ground at Tiffany. The maximum water surface of the proposed Rolling Hills elevated tank is 590 elevation. Pumping lift, excluding friction, would then be 135 feet under the worst conditions. The performance curve for the smaller pump, assuming only five impellers, indicates it should provide 300 gpm at 150 feet total head. The larger should give 700 gpm at the same head. -8- It appears therefore that the existing Tiffany Park pumps will pump water to the proposed elevated tank. However, it is recommended that the City write Pump, Pipe 6 Power in Portland to confirm the duty of these pumps. It is believed that firm installed the pumps and modified the smaller. Their records are excellent and the data should be readily available. RELOCATION OF EXISTING TIFFANY PARK PUMPS TO ROLLING HILLS ELEVATED TANK The ground level tank is not yet scheduled for construction, and the practical difficulties of maintaining the supply during relocation of the pumps would be considerable. In any event, the pumps would r�yuire overhaul before reinstallation. It has been shown that the existing pumps are too small to meet the system demands and fire requirements in the fully developed are;., but they will serve for some time to come in their present location although the area is developing quite rapidly. It is recommended that new pumps be purchased for Rolling Hills elevated tank and that the existing pumps be utilized in the proposed Talbot pump station to supply the south area if the duty is compatible.

The low bid of Pittsburgh-Des Moines Steel Company has minor informa- lities of (1) sales tax computation error, (2) Proposal not dated, and (3) no bid on the alternate designs. These Informalities do not, in our opinion, effect the intent of the Proposal and we recommend that they be waived. The preliminary design has been reviewed and found to appear acceptable. The following tabulation shows the total estimated project cost for the various size tanks: Tank Size Ites 30G,000 400,000 500,0DO 1. Tank (per bid) $152.412 $178.423 $206.662 2.

In view of the bids, we recommend that a 300,000-qallon tank be constructed. The tank will act as a pressure control for the area and the future ground storage as the fire protection, thus elimi- nating the necessity of a larger elevated tank. it is recommended that the low bidder, Pittsburgh-Ups Moines Steel Company of 6ellevue, Washington, be awarded the contract in the amount of One Hundred Forty-Five Thousand Eight Hundred Forty-Nine Dollars ($145,849.CO) plus state sales tax of $6,563.21, making a total award of One Hundred Fifty-Two Thousand Four Hundred Twelve Dollars and Twenty-One Cents ($152,412.21).

Hamilton Reference: 300 M.G. Elevated Tank i Renton, Washington i Gentlemen: We hope by now, you have had a chance ;o look over the information we sent you on how we figure earthquake factors on elevated tanks. The government manual sets forth an az:e7table method of computing deflection due to earthquake. our re"c3 is conservative in rela- tion to it since we consider only deflection of the reds in the tower. In looking over the 1962 CBaI paper, we find that they agree with our approach in many ways: 1) the period of vibration (formula 3) , 2) horizontal components of rod loads (formula 4) , 3) deflection of the tower (formula 5) and 4) the highest stressed panel is parallel to the direction of force and the force in this panel is the total load divided by half the number of co?•_.ns (appendix 2) . Where we disagree is the assumption t:-.at moment resistance of the column connection to the shell upsets zhe deflection. Design is based upon all connections being pinre°. If CB&I follows their procedure, then they must design their columns for combined axial and bending, which complicates the tcr�er design. It also follows, if columns are resisting horizontal r_:enent, that the rods and struts will be carrying less. Therefore they will be s�mallcr and Castigliano's deflection will increase •:hich will change everything. Our method of tower calculation has b=en used and accepted by the trade over many years. We know from -:_actice and results of earth- quakes on our structures, that our a-_zrcach is soand. If you would like us to stamp our drawings with a :Washington Registered Engineer, we will gladly do so. We have started fabrication of the to and col:Lmns bared upon your verbal approval on August 18.

Conyers Gentlemen: We have reviewed your calculations again and the methods -used in your design of the tank support structure. We believe that the method incorporating column resisting moments in the support tower more nearly reflects the actual field conditions rather than the method assuming pin connections. We have done further analysis of the structure, checking the columns, diagonals and struts to see if any of them are overstressed. We have found that sane of the mmeawers will be overstressed when the combined axial and bending deformation of the tower legs is accounted for. we therefore cannot approve your drawings of the tower support structure.

Conyers =-MG Elevated Tank Renton,2.jhinoton Gentlemen: To confim our telephone conversations of 26 Aunust 1969, we are unable to approve the shop drawings for above tank hued nr the calcutat!ons submitted by you. The basic disagrea'mnt is in the design of the tower supporting struc- ture for Zune III earthquake loading. It is our contention that the design cmputations should reflect as nearly as possible the conditions that will apply in the field. The columns supoortinc the tank will absorb a portion of the lotoral earthquake load in bending due to the imposed and restraints at the tank shell and culwn footings which will change the period of oscillation of the tank from the idealized structure assuminq all pinned connection. Before we can approve the shop drawings, we must be satisfied that the tank and its supporting stricture has been desioned to meet the conditions which will anpiy in service.

Conyers City of Renton, 4!ashinoton Gentlemen: We have reviewed the calculations sent to us on 5 September 1969. We believe the following items need to be reviewed by you. 1, structure analyzed by STRUDL was incorrect in the following items: a. Dimensions and areas used are not as shown on the shop drawings. b. Vertical supports at the top of the structure are not there as you have indicated. That is "Pesultant Joint Loads" should Indicate "Y Force" at joints 10, 11 , and 12 equal zero. C. Intermediat,: supoorts at panel points need to be used on the end columns to obtain symmetrical distortions in the structure. 2. Based on the STRUDL output some of the diagonals, struts, and columns are overstressed. Let it be noted here that the direction of loading for maximum stress in the struts and diagonals is parallel to one panel face, not the same direction as for maxirum tower stiffness. lie have also analyzed the tower structure using the STRUDL program, beino careful to follow the points set forth above. t�e believe the following results to be representative of the structure as s own on the shop drawi%s. 1. Earthquake Factor - 12.9% CITY 0` REN►00 2. Diagonals and struts -t overstressed. �;�'_, 3. Columns are overstressed under corbined axial and bending loads.SEP I8 1969 This condition occurs only near the colurn bases and may be relieved byENGINEOING DEP using a thicker column elate in the lower 15 feet of the column. T, Pittsburgh-Des Moines Steel Company 16 Septembe- 1969 Page -2- 4. Footings are overstressed in beam shear. This problem may be relieveo by eniaraing the pedestal base to a minimum of eight feet square. We submit the results of our analyses to you only as a suggestion for design. We respect your position as the designer, and do request detailed design caiculations before we can approve the shop drawings. Upon. reviewing your letter of 3 September 1969 for extra costs, we cannot Justify these. Our contention has been and still is that the structure should be designed according to actual field conditions including actual dimensions, member size and restraints in accordance with the UBC code.

We have reviewed your calculations sent on 23 Dctober 1969 and have further discussed then with Dr. Norman Edwards of your company on 3C ilctouer 1969. We nave not been able to resolve our disagreement with your approach. The analysis should be oither conducted on the entir structure or one half the symmetrical structure which you did not do. Thi> gave erroneous results with which we cannot agree. We nave enclosed a summe•, review of your calculations which indicates our disagreement. Also -nclosed is a copy of our analysis of the tank l,, STRUDL and associated earGlquake and footing design calculations. It is our hope that we can come to some agreement in the near future with respect to the tank analysis. Bused on our calculations and using a high yield strength steel for the tower columns, the tower str'icturt seems adequate. The tower footings are overstressed in sh.ar cased on the enclosed date. We will be willing to ";ease the shop drawings Cased on our calculations if we have data on toe cols yield strength and the footings are corrected. In our conversation with you on 29 Dctober 1969 there was mention that t+re hulerial to he used for the taw.- columns was "reject pipe." This concerns us IA th regard to the adequacy of the member. The Contract Specifi- cations require mill certificates on all the steel that goes into the tank and that the steel meet the appropriate ASTM Specifications. If the pl Dr can pass the ASTI, Specifications and a mill certificate Is provided, then the reject pile" would be Acceptable. We are taking the liberty to send the calculations directly to Dr. Edwards along witn your report and STRUOI runs. Very truly Yours. CORNELL, 40"0, HATES 6 MERR1'iiELD Michael E.

Oentlemen: It is PDM's contention that our original calculations dated ,Tune 18, 1969 were sufficient to show compliance of the design with the annll- cable codes and specification. It is understandable, however, that one could be mislead Into believing that any fixity of the column ends would result in a significant increase in the earthquake factor. To show this Is not the case, PDM analyzed an approximate model of the tower. According to your Sentembei 16 letter, CH2M now agrees with PrM on this point. However, in that sane lette-, additional criticisms of our des' •n were presented. We are beglnnin{ to fee: harassed. Nevertheless, in an effort to ;et the job started am"-in, the enclosed calculations were orenared to show oonclusively that the columns are not overstressed under combined axial and bending stresses and the footings are not overstressed In shear. It is true that the load, 'n the tower would be distributed differently If the direction of load were different; however, because the tower Is less stiff in the other irections, the total earthquake load would be less in the other direction. It Is our judgement that It Is suffi- cient to show that the tower stresses are within allowables wher the tower is subjected to the maximum earthquake load. We trust these additional calculations have covered the points bror ;ht Up in your letter pf Sentember 16, and you rill now approve and reloase our ,rawi—sfor construction. These calculations and the computer print out we considered as property of PDM. We request that you do not reproduce any portion thereof and return the complete set to us after you have finished your review. We will re-evaluate our schedule when aorroval of our drawln;a are received. Very truly yours, P TTSB?7R0H-ne:S MOINES STEEL CDMPA!4v v 7 Aft--.,J. P.

We call to your attentior the following information and data regarding your statement that our claims are unfounded. 1. We received, August 25, 1969. your letter of August 22. 1969 stating Cornell, Howland, Hayes and Merryfleid could not approve drawings of the tower. The tower demon also affected the foundation design as you stated the steel column to concrete foundation pedestal must also include moment resistance. On August 25, 1969 we checked the progress of foundation construction and on August 29, 1969 talked with your Mr. Michael F. Hamilton br phone. Mr. Hamilton stated foundation approval was based on future rH?" tower design acceptance. Later, On August 26, 1060 we tr :ked further with your Mr. Hamilton and Mr. Frickson who stated that design with moment resistance by the foundations wan the only approach. As foundations were designed otherwise, we were left no alternative other than to stop construction. rur letter of August 27, 1969 to rH?M with a copy to the city stated our Position, offering our explanation end requested added com- nensation for the change in scope. On August 20, 1069, our Mr. Wendlandt personally called at the offices of CF?M and was informed that we could proceed with found- ations if the column pedestals were changed from 6' to 7' wide. ".Tie was a change in scope. We received CH2" letter of Qeptemter 16, 1960, stating the found- ations were over stressed in "bear shear" and therefore footing design is a problem. The above illustrates the vccillation on foundation approval froT Renton, Washington 397'j4 January 22, 1970 Page -2_ the original in July 1969 until Sep tsmber 16, 1969 on the part Of CN2M, Also, It is difficult to how the action of PDM was unilateral and without nnotieedtotthe that customer or his repressntatives. 2• Rabrieation of the tower columns was started a few days prior to approval of drawings based on telephone approval by Me are Hamilton and Rrlckson of August 18, 1969.
