No. 400, Foundation Plan, United States Court House INTRODUCTION The object in writing this thesis is to describe the type of foundation, the difficulties that were encountered in the driving of steel tube piles (cast-in-place); and to present complete data on test piles in connection with the foundation work of the (New) United States Court house, Pew York City. It is not my intention to present any rules or formulas to be used as a guide for similar foundation work. 1y purpose is to describe the progress of the pile driving Operations, the changes that were made necessary due to soil conditions, and to treat this thesis along the following lines: 1. 7. Driving of the first few contract piles indicated that the design of piles as specified was not ad- apted to the soil conditions of the site. The driving of various types of test piles to test the nature of the soil and to determine the type of pile to use. Complete records of the results of driving test piles. Change in the contract based on the results of the test piles. Special conditions that were encountered in the driv- ing of piles. Final results of the pile driving in various locations on the site. Conclusions regarding the data covering the pile foundations. . ...-...-H—.-——o..-c hull-9-.-- - '-1r-- .p'l- n (a I was assigned by the United States Treasury department, Hashington, D. C. as Construction nngineer to sugervise the work of the Foundation Contract for the (Sew) United States Court House, flew York City. The data covering the various types of test piles, load tests, and reeoris of the pile driving operations of the foundations for the (New) Court House, provided such and inter- esting record of the events of the pile foundation work that I have arranged the data in the form of this thesis. In 1931 Conéress authorized the Secretary of the United States Treasury Depart ent to construct certain Public Build- ings in various s ates and the Treasury Degartnent set a t limited cost of $8,250,000 for the (New) United States Court house, New York City, as one of the buildings. 7 The present United States Court douse which is located o W .I-‘I—C near the historic City Hall, borough of Hanhattan, in Nev York City, was built shortly after the Civil Jar. It has be- come obsolete and does not meet present day requirements. The (New) United States Court House is located at Foley Square and Pearl Street, a short distance from the City Hall. Cass Gilbert, was the architect for the (New) Court ' ' *7 ‘fifirm—mw MW?- 1 House and by contract with the Treas‘ry Department was author- ized to prepare all drawings and specifications for the founda- tions and the super—structure. The building was designed as shown by the frontispiece of this thesis. The tower section 0f the building is thirty-seven stories high, and the lower section six stories high above street level. The building has 0] a steel skeleton framework, and is faced with granite. The architect anticipated that there would be difficul- ties in connection with the foundation work for the New Court House because in the early days of New York, part of Collect Pond extended over a portion of the north western part of the site, and the surrounding area consisted of marshy ground of uncertain conditions; however as the city grew this area be- came made ground and all signs of the pond and marsh disap- peared, and buildings and streets were built on this area at one time or another. Drawing X—2 shows in detail the nature of the soil for various depths at different locations of the site. Some test borings were taken to a depth of 200 ft below grade level, and no rock was encountered at that depth. The soil con- sisted of sand and gravel stratas of various densities. The Foundation Plan Drawing No. 400 shows the spacing of the piles, the size of the footings, and reinforcing bars. The typical footing detail shows the pile cut off, the con- crete pile cap and location of the reinforcing bars. The tower section of the building is supported by foun- dations that cover the full area of the base of the tower and consist of piles 3 ft on centers (about 2000 of them) which -are covered by reinforced concrete mats. The six story part of the building is supported by iso- lated footings that consist of pile clusters which are covered by'concrete pile caps. In general the ground water level was about 2 to 4 ft 4 below pile cut offs. At the elevator pits the pile cut offs were 4 to 5 ft below water level. These areas were sheet piled in order to permit work below ground water level. Pumps were used to keep the water level below pile cut offs at the elevator pits during the construction work. Pages 5-1, 8-2 and 8-5 cover the specifications for the Cement, the Aggregates and the Mixtures, the Concrete Pile Foundations, and describe in detail full requirements of the above materials and of the piles. All piles were specified to be cast-in-place steel tube piles of 12 in. inside diameter, of not less than 3/8 in. wall thickness, and each pile was to have a tight fitting steel shoe or point. The estimated average length for all the piles was to be 50 ft from tip to cut-off. ‘ This type of pile was considered satisfactory to safely support the load within this length of pile.. Lump sum bids were required for the excavation and foun- dation work, and the contract was let to the lowest bidder, George J. Atwell Foundation Corporation of New York City. The architect estimated that the excavation and founda- tion work would cost about $1,000,000. At the completion of this work the cost was approximately $800,000. The old buildings on the site were removed to general grade level, and photograph No. 2 is a view of the site at the time the foundation contract was let. Grade level did not in- ¢iicate in any way the extent of old foundations. An interest- iJngjpart of the work in connection with the foundation contract was the removal of these obstructions which consisted of heavy concrete walls, steel girders, grillage beams, and wood piles. Air drills, dynamite, and pile pullers were used to remove this material. Photographs No. 10-26-55-57- 38-40 show the obstructions. These obstructions were removed by George J. Atwell Foundation Corporation. This work which became part of their contract was done on a cost plus basis as an estimate of the cost was impossible because these obstructions were uncovered only as the excavation work progressed. Excavating was started along the northern portion of the site and carried down to pile cut-off level. The piers 93 and 94 were staked out to show the location of the piles and preparations were made to drive piles to test the soil at this location. DRIVING OF THE FIRST FEW CONTRACT FILES The specifications required the piles to be steel tubes of not less than 12 in. inside diameter and of 3/8 in. wall thickness with cast steel shoe fitting the tube so tight that no water could enter it. Piles twenty to forty feet long were to have no more than one splice or sleeve. The estimate for the average length of all piles was 30 ft long from tip to cut off. There was a total of 4180 piles. The piles were to be driven to a final penetration that would safely support 36 tons, which was equal to a penetra- tion of 5/16 in. per blow or (9 blows per 5 in. penetration), (38 blows per ft penetration). On page 8-1 is stated the formula to determine the bear- ing values of piles. On page T is a table of various bearing values for piles based on the penetration per blow, also for the number of blows per in., per 3 inches, and per ft penetra- tion of the pile. These bearing values have been derived from the formula for various penetrations. The first pile driving was started in piers 93 and 94 using pipe tube lengths of 30 ft. A steel shoe was placed on a 30 ft section of tube and driven into the soil to cut-off. The soil offered very little resistance to this 50 ft pile section therefore an additional 30 ft tube was added to this pile and driven to cut-off making 60 ft of pile in the ground. IEven at this depth the soil did not have enough bearing value to support a 36 ton load according to the formula. Additional piles were driven to a depth of 60 ft intend- 7 ing to compress the soil and in that way obtain the required bearing value, but the soil did not compress to the extent of having a safe bearing value, therefore it was not considered advisable to drive any piles to less than the safe bearing load of 56 tons. The remainder of the piles in these two piers were driven to the requiredbearing value and the lengths of these piles varied between 65 to 94 ft. These piles exceeded the esti- mated average length of 50 ft by as much as 100 to 200 per cent. During the driving of the piles in piers 93 and 94 it was noticed that there was no upheaval of the soil but a slight settlement between the piles. After standing a day or so some of the piles had a head of water in them, while other piles remained perfectly dry. An inspection was made of the dry piles by using a mirror to reflect the light from the sun down into the pile. On dark and cloudy days an electric light with a shade was lowered into the pile. This inspection showed that the various sections of the piles were out of line with the adjacent sections (referred to as kinked piles) and that the whole pile was out of plumb. The soil had become compressed due to the driving of the piles. Therefore when additional piles were driven thru the varying densities of compressed soil the dense soil forced the bottom sections of the piles out of line and away from the adjacent piles. The splice or sleeve did not form a rigid 8 connection and the pile kinked at each joint or section of the pile. Some of the piles that contained a head of water leaked so badly that it was impossible to pump the water out of the piles to inspect them. Other piles were pumped dry, inspected, and were found to be kinked and out of plumb to a greater ex- tent than the dry piles and that the piles leaked at the sleeves. Load tests were made to determine the bearing values of some of the piles that were not driven to the required pene- tration and on piles that were badly kinked and out of plumb. Pages T-l and T-Z show the results of the load tests on some of the piles in piers 93 and 94. Under the column of "bearing value" is the bearing value of the pile according to the blows per inch. The column "settlement under load" is the settlement underloadings of 30-60 and 100 T. The speci- fications allowed 1/2 in. settlement under 60 tons test load for a 36 ton bearing value. Under "remarks" is stated the condition of each pile. The first two piles were driven by a Vulcan Hammer No. 2, which was too light in weight to use in driving the piles. All other piles were driven by a Vulcan Hammer No. l of 5000 pound weight. The short pile #1 pier 93 did not show as satisfactory results under load test as the long piles even with the higher 'bearing value of 100 kips. The pile driving and the load tests in piers 93 and 94 indicated a soil of loose formation with a high percentage of voids and a high water content. The soil, to a depth of 40 to 60 ft did not have much resistance to a straight pile during the driving, but after the pile stood,it developed a frictional resistance with the soil and showed ahigh load test. The short pile built up a point or bulb resistance (bearing) that would dissipate as the pile stood and the soil at the point would relieve itself on account of the voids and water. The results obtained by an inspection of the piles and the overrun in the lengths over the estimated length of 30 ft showed that the type of pile specified did not quite meet the conditions of the soil. It was decided to drive test piles to determine the type of pile to use for the foundations. 10 TEST TILSS Test piles were driven at various locations on the site and the following types and sizes of piles were used: 1. Pipe piles, 12"-16"-18" diameter of 3/8" wall thickness, with cast steel shoe or point. 2. Precast concrete Piles, Tapered. 3. Standard Raymond Concrete Piles, Tapered. 4.. Step Tapered Raymond Concrete Piles. Sk-l. Detail of Pipe Pile and Precast Concrete Pile. Sk-Z. Detail of Standard Raymond Concrete Pile and Step-Tapered Raymond Concrete Pile. Pages 13, 14. List covering the data on test piles. The Standard Raymond Pile consisted of steel shells, (spirally reinforced) and a boot placed over a collapsible mandrel. This mandrel incased in. steel shells and boot, was driven to a proper penetration. The mandrel was col- lapsed and withdrawn, leaving the shells and boot in the ground. The shell was inspected; if found dry and satisfact— ory it was filled with concrete up to pile cut-off. The shells come in lengths of about 8 ft and of dif- ferent gauges of metal and of wire spirals (see page T-6 for different gauges) Different gauges of shells were used, depending on the nature of the soil the piles were required to penetrate. Where there was coarse sand or gravel, a gauge of shell was 'used that would resist the cutting action of the soil, and prevent the sand or water from entering the pile shell to the ll detriment of the concreting. The Raymond Step Tapered Pile consisted of heavy cor- rugated shells placed on a non-collapsible core, which was driven to a proper penetration; then the core was with- drawn and the shell filled with concrete to cut-off. This pile was made up of shell lengths of 8 ft sections with an increase of l in. in diameter per section of shell. The Precast Concrete Piles were cast in 40 ft lengths, in wood forms and allowed to set for twenty-eight days be- fore being driven. The test piles were driven to a prOper penetration, and that portion of each pile extending above the cut-off was removed. The pipe and shell piles were filled with concrete to pile cut-off. In driving a few of the Raymond Piles, it became evident which lengths of shells to use in order to reduce the waste of shells above cut-offs. For the Precast Concrete Piles that were made up in fixed lengths, tests had to be made to determine a length of pile suited to the soil and not have unnecessary waste of pile extending above the cut-off. Pages T-2 to T-13 are the penetration logs of the test piles that were driven at various locations of the site and are indicated on the Foundation Plan in this form. 0 Page T indicated the bearing values in pounds for various number of blows per inch, per 3 inch and per foot penetration of pile. ' In the penetration log of a pile the first column indicates depth and opposite is given the number of blows - \ ’3" 12 per foot for that depth of pile. Each foot of pile was mark- ed off and a count was made of the number of blows for each ‘foot of penetration. The soil did not have much resistance to a straight pile for the first 40 to 60 feet as shown by pages T-3, T-4 for 12 in. piles. ~ In pier No. 47, pile No.10 reached a safe bearing pene- tration at 40 ft. In pier No. 93, pile No. l and 10 were the last piles driven, and are along side of one another. The 12 in. pile was driven first to a depth of 62 ft; to a safe bearing pene- tration. The 18 in. pile reached a safe bearing penetration at a depth of 17 ft. Pile No. 1-18 in. is referred to on page 4. In pier 238, pile No. 44 reached a safe bearing penetration at 76 ft and was driven to a depth of 103 ft. The penetration of the pile shows the various densities of the soil. In driving the straight pipe pile, the bearing value varied as the pile penetrated the various stratas of soil. The bearing values increased or decreased with the nature of the soil and was noticeable with the 12 in.pipe piles, which tended to build up a safe bearing value below a 40 ft penetration. See pages T-3, T-4 for results.- For a straight pile, it is sometimes advisable to over drive the pile; that is, to drive the pile beyond the re- quired bearing value in order to determine the value of the underlying stratas of soil and make sure the pile rests 4.11131. on a firm bearing soil. Some pipe piles in piers 83, 96, and 238 of the 12 and 16 in. sizes were driven to a depth of about 30 ft, to less than the required bearing value. These piles under a load test showed a settlement of several inches for the 12 in. and for the 16 in. over 1 inch. This showed a soil in which the point bearing value should not be considered for the first 30 ft. See pages T-14, T-15 for the load tests on 30 ft piles. During the driving of the Standard Raymond Piles (taper- ed) and the Precast Concrete Piles (tapered) the soil was compressed along the sides of the piles. This built up a frictional resistance that provided the bearing value for the piles. In this soil the point bearing value was neglig- able. The lengths of the tapered piles averaged from 20 to 22 feet for a safe bearing load. In driving a tapered pile in this soil, the bearing value builds up fast, and in over- driving, the penetration decreases very fast and the pile comes to refusal. The penetration ranged from 30 to 34 ft for the step- tapered piles, and being of a small taper, developed into a frictional pile of a longer length than the tapered pile. Two of the precast test piles were pulled out and photograph No. 68 shows one that came in contact with a boulder or some obstruction and was damaged. These piles were pulled out to see what effect the driving had on the piles and showed no defects except for the one broken pile. 14 There were certain conditions of the site to take into account in determining the type of pile to use. The subway extends along the site at a depth of 20 feet below the cut-offs of the piles. There is a possibility of future subway or sewer work adjacent to the site and at such a depth below street grades that a length of pile was considered that would reach a depth so as not to be disturbed by this form of construction work. It was decided that the combination of 12 and 16 in. pipe piles would be best adapted to meet all the conditions of the site, and put the bearing down at a depth out of danger of being disturbed. The contract was revised on an estimate that the re- maining 4,108 piles would be 50% - 12 in. piles, 46 ft long, and 50% - 16 in. piles, 38 ft long. At the completion of the pile driving there were: 3,152 - 12 in. piles, average length 46.52 ft. 956 - 16 in. piles, average length 55.25 ft. The contract was based on a unit cost of $2 a ft. for 12 in. piles and $3.80 a ft. for 16 in. piles. An adjustment was made in the contract covering the overrun of the 12 in. piles and under run of the 16 in. piles. 15 RESULTS OF THE PILE DRIVING After the change in the contract, preparations were made for the pile driving operations. Stiff leg derricks were used with leads that could handle pipe.lengths up to 40 and 50 ft. These standing leads rested on sills and were held in position by guy lines; the leads were easily moved after the driving of each pile. The length of the boom and the height at which the derrick was set deter- mined the area that the leads could reach and drive piles. It became necessary to shift these derricks to new locations to drive additional piles. Crane rigs, equipped with leads, that could be moved about under the rigs own power were also used and could handle pipe lengths up to 40 ft. Photograph No. 93 shows the two types of rigs used. The Warrington-Vulcan No. 1 single acting hammers were used. The weight of the ram was 5000 lbs. and had a drop of 3 feet, the speed of the hammer was 60 blows per minute. The best results in driving piles were obtained by keeping the speed of the hammers between 55 and 60 blows per minute. If the speed dropped below 50 blows per minute there was a noticeable drop in the penetration of the pile, which affects the load bearing value of the pile. A complete record was kept of each pile driven and re- corded as follows: Last No. Pier Pile Date Blows Insp. (Pile length) Date Insp. No. No. Driven Per 3" by 12" 16" Concreted by 16 A convenient method of noting the penetration of a pile was to mark 3 in. spaces on the leads and a mark on the pile, then count the blows for each 3 in. of penetration as the pile was nearing the safe bearing vale. This re- quired 9 to 10 blows per 3 in. penetration for 36 ton bear- ing value. Before concreting the piles were inspected to see that they were dry and in a satisfactory condition. Any water or mud that seeped into the pile was pumped out before con- creting. The points and sleeves were made to fit snug in order to remain water tight. The piles were always concreted as soon as possible, so as not to stand over night,as the water pressure would cause leaks when left without concreting in many cases. Transit mix concrete was used thereby eliminating the need of a concrete plant at the site. This method proved very satisfactory. In the driving of the 12 and 16 in. piles, it was a question as to which pile would be best suited to use for that location. The northern portion of the site showed a «deeper penetration than the eastern and southern portions. .A 16 in. pile was tried out first in the isolated piers, and as long as the piles were over 40 ft in length, 16 in. pilesvere used. It was noticed that the first few in a pier would reach a depth of 60 to 80 ft then as additional piles were driven about 40 ft was sufficient. Then 12 in. piles were driven and the same result was obtained as ad- ditional ones were driven. 17 It seemed that the first few piles driven compressed the soil after reaching a good depth so that the addition- al ones driven in that pier could be shorter. Adjacent piles showed entirely different results in the hammer resistance (blows per 3 in.). For the first few piles driven in a pier, the soil did not offer much resistance in the various strata. Then as more piles were driven, particularly in piers on the northern portions of the site, the soil was compressed in the top stratas of 15 to 30 ft below cut-off and it required ex- tra hard driving to penetrate these stratas, requiring from 50 to 100 or more blows to a foot and then decreasing in some cases to 5, 6, 7 blows per 3 in. penetration. The first group driving of piles was in pier 244 and 245. A safe bearing penetration was reached for some piles at lengths of 25 to 35 ft, then by a little over driving of these piles they would break through the strata and the pene- tration would be more than a safe bearing value. When all the piles had been driven in these piers, the piles that 'were less than 25 to 35 ft long were re-driven. In some cases the pile started off at more than the safe load penetration at the first hammer blow, while other piles required over driving to start the pile and penetrate to another strata of safe bearing value. It seemed that for the short piles, a bulb resistance ‘was built up and while the pile rested, this bearing value would.disapear due to the voids in the soil and the water. It was necessary to get a good depth for the first piles 18 driven in a pier and over drive the others to a good depth to compress the soil; so that the last piles driven rest- ed on the compressed_soil between the long piles, and the whole group acted as a unit. A 45 degree point was used on the end of the piles and where there was hard driving, a 60 degree point was tried out on short piles and driven to refusal. Some addi- tional depth was obtained by using a 60 degree point but not enough to warrant their use. Pier 238 Test pile No. 44 in pier 238 was driven to a depth of 103 ft, the penetration log page T-3 and T-4 shows the blows per foot for each foot of this pile and at a depth of 76 ft reached a safe bearing value of 36 tons according to the hammer resistance. Page 20 is a pile record of pier 238 and shows the order in which the piles were driven. Piles in piers 244 and 232 were driven previous to the piles in piers 238 and 239. Sk-3 is a plan of pier 238, showing the pile number, order driven and the lengths of the pile. The driving of piles in this pier compressed the soil to the extent indicated by the lengths shown in the pile record. Piles 33, 42, 51, 15 and 6, were over-driven to obtain the lengths as given for these piles, the remainder of the jpiles driven in this pier were driven between already driven piles, with the results as shown by the short piles. rill; . l .. 1'. i m~ 19 After standing more than two weeks, it was decided to re-drive the piles No. 6, 8, 22, 31, 40 and 49 and to note the additional penetration. In each case it required con- siderable over-driving to obtain the additional penetration. The additional lengths of these piles and the penetrations were as follows: Pier 238 Final blows Pile Additional No. Blows hinimum Maximum per 3" before No. lengths per 3" at No. blows No. blows re-driving start of per 3" per 3” re-driving 125 8 12'8" 74 60 250 70 6 30‘7" l4 16 250 300 40 1‘3" 40 40 140 refusal 31 - 8'6" l6 16 200 300 22 6'9" 80 80 140 refusal 49 35'1" 30 12 72 The first column indicates the final blows before re- driving and the fourth column indicates the number of blows at start of re-driving and shows that this bulb re- sistance is reduced as the piles stand. According to these results the re-driving of short piles did not indicate that much was gained by the addi- tional lengths of the short piles, if a good penetration was obtained by the first piles that were driven in a pier. Pile R0. 30, 12'-2" long was tested with a 60 ton load and showed a settlement of 1/8 in. 11"“ .r YORK, N.Y., 3T. Ha.

Skb3, Plan of Pier-238, giving the pile number, order they were driven and the lengths for the piles. 21 Piers 212 and 213 In piers 212 and 213 the pile driving was started at the column center, driving toward the center between the columns. The short piles shown in the schedule on print Sk-4 were the last piles driven in these piers and were driven to refusal. The long piles in the same schedule were adjacent to the short piles on each side and are shown by the part plan of these piers. 0n print Sk-4 is a report of soil borings between piles (15 and 18),(16 and 17) which were made by sinking a small pipe into the soil by using a weight of 280 pounds with a hammer drop of 2 ft. It shows the blows per foot for a depth of 30 ft, the extent the soil had been compressed by the driving of the short piles, and the extent the soil had been compressed below the short piles adjacent to the longer 'piles. In driving the 12 and 16 in. piles in the pile clusters, various methods were tried out to see which would provide the better penetration. The driving of piles in alternate rows first allowed these piles to obtain a good penetration and these piles compressed the soil to such an extent that in driving between the long piles, a short penetration was obtained for the last piles driven. It was found that the best results were obtained in the pile clusters by driving the first piles under the column centers, then working towards the outside of the pile clus- ters. In the tower sections of the foundation pile driving was 22 started under the column centers, the meeting points were half way between column centers, with the result that in each case the long piles were under the column centers and the short piles occured at points midway between column centers. There are about 2000 piles in the tower founda- tions. During the driving of these piles there were no signs of any upheaval of the soil between the piles or any indica- tions at the surface showing a displacement. This indicated the soil contained a high percentage of voids and had a high water content. The driving of piles in piers of the northern portion of the site showed various stratas of soil of varying densities. The soil was easily compressed and resulted in a wide range of pile lengths in the same pier; particularly the isolated pier 90, and piers where there were many piles in a group. The soil of the eastern and southern portion of the site was of a uniform density. The piles in penetrating this soil reached the required bearing value gradually. The lengths did not vary greatly from the average length for a pier. Page P-15 shows the average lengths for the 12 in. and 16 in. diameter pipe piles in piers at various locations on the site. Page P-16 is a record of load tests on piles picked at random to be tested, as required by the specifications (paragraph 109). A platform was made to fit the top of the pile and cast iron weights about 12" x 12" x 4' weighing 2000 lbs. each were used. r 23 The following is a list of some piers and a complete pile record of the piles in these piers.

The soil consisted .of sand in a loose formation, saturated with water. On account of the voids and water the sand was in suSpension and easily displaced. While the straight pile was being driven and in motion it was possible to penetrate the soil to a considerable depth, then as the pile stood the sand and water settled around the pile, thereby developing additional bearing value above the value indicated by the hammer resistance. The piles supporting the tower section are 3 ft on cen- ters (2000 of,them) covering an area of 130 by 130 ft. The soil displaced by the driving of the piles was absorbed and compressed between the piles without showing any displacement of the soil at the surface. This condition of the soil in- dicated the large amount of voids and water contained there- in. The soil in general offered little resistance to the first piles driven in a cluster or group for a depth of 30 to 40 ft, beyond this depth the soil varied at different locations of the site. SK-5 Graph showing penetration of piles and (pages P-11 and P-13),penetration logs of piles show this condition with reference to the straight piles. Loads tests on straight piles driven to a depth of 30 ft.showed a settlement under the required test loads. Straight piles driven to less than the required bearing 25 value, and to a depth of 60 ft showed under the test load a safe bearing value. The tapered piles had a small penetration in this soil. The piles built up a bearing value along the sides of the piles referred to as skin friction bearing. The piles de- ve10ped the required bearing value in the first 20 to 25 ft of soil. The nature of the soil and the possibility of future subway or sewer construction work adjacent to the site made it necessary to consider a foundation that would not be affected by adjoining excavation or construction work, It was considered that the combination of the 12 and 16 inch pipe piles were best suited to meet the conditions affect- ing the site. The 12 in. and 16 in. piles penetrated the soil and placed the bearing of the pile foundation at a safe depth below anticipated construction work adjacent to the site. Pipe lengths of 30 to 50 ft long reduced the number of splices and also eliminated kinked piles. Pages P-l to P-10 inclusive provide a complete record of the 12. and 16 inch piles in some of the piers at dif- ferent locations of the site. These piers indicate the average conditions of the piles for the piers in these loca- tions. Page P-l5 shows the average lengths of the piles in some 26 of the piers at various locations of the site. The lengths of these piles indicate the average lengths for the piers in these locations. The piles in the isolated piers were capped by concrete (reinforced) to distribute the column load over the full area of the pile cluster. The concrete caps are shown on photographs No. 87, 91 and 95. Drawing No. 400 Foundation Plan shows part of the tower section supported by three concrete mats. The outside mats contain two plate girders. The concrete mats are 9 ft thick reinforced with steel bars tOp and bottom so as to distribute the column loads over the pile foundation. Photographs No. 99 and 104 show the top reinforcing steel of the mats. At the completion of the foundation work it was considered that the combination of the 12 and 16 inch pipe piles met all the conditions of the site and penetrated the soil to a safe depth that provided a safe foundation for the structure designed for the site. .l YCRK, 3:.
