Tunnels Driven With Shields — {continued.) 250. Where screw piles are driven to a comparatively shallow depth, the Eiifiineer may require the Contractor to drive a sleeve, of somewhat similar design to the screw pile sleeve elsewheredescrihed, down to the bed rock; the rock shall then be dressed ofif to give a solid and uniform bearing for the screw pile, and in such case, tlie Engineer may adopt piles without screw points. The mate- rial will be excavated from inside the sleeve and the screw pile shaft put down to the required solid foundation on rock and filled solidly with concrete. In such cases the screw piles will be paid for at the rates for the various materials in jilace and the price for bedding same on rock as per schedule in contract. 251. Should the Engineer wish to ascertain the nature of the ground in which a screw pile has come to rest or is being driven through, the Contractor shall put down a boring tube and obtain dry samples of the ground and if necessary blast away any boulder that may be obstructing the downward jirogress of the screw pile. The Contractor shall furnish all tackle, power and labor necessary for making the borings. For this work he will be paid the net cost of labor plus 15 per cent. 252. As the lengths of screw piles cannot be definitely predetei mined it wnll be necessary to withdraw the top section of all screw piles and fix in its place a special section of the proper length. 255. The Contractor must provide for the delivery of these special sections within three days from the date of order, which will be issued as soon as the exact length required is determined. 254. To enable the top section of a screw' pile to be withdrawn and the special one substituted a thin steel sleeve will encase the screw pile at the top to a depth sufficient to form a bulkhead to retain the ground during the o])eration. The collar or upper portion of the sleeve which is thicker will be turned to fit within the bore of the cast steel segments. Previous to the set- ting of the sleeve, a temporary cast iron collar will be furnished by the Con- ti’actor as part of his plant and will serve to guide the screw pile and maintain it centrally so that the sleeve collar may be easily placed in position when the screw pile is driven to a sufficient depth to permit it. 255. The dowels of rolled steel for connecting screw' pile sections are to be neatly and accurately cut square and clean and turned to the exact diameters required. 256. The head of screw pile at junction with cast iron tunnel lining is to he made thoroughly watertight and the slot between tunnel segments for passage of screw blade is to be stopped with an iron “ filler” casting and made watertight by rust jointing. 60 PENNSYLVANIA, NEW JERSEY AND NEW YORK RAILROAD. Tunnels Driven With Shields — (continued.) 257. It is assumed that the ground will rise within the screw piles to about concrete within screw the heads of same. This ground shall he removed in every case to a depth within the screw pile of 12 feet and the screw pile filled with concrete up to the underside of the steel diaphragm plate. A wrought iron pipe 2 inches in diameter for grouting shall be built in the centre of the concrete column, ex- tending vertically through it. The steel diaphragm plate shall he bolted down Grouting in screw pue. and through the grouting hole in same and 2 inch pipe, cement grout shall be injected under a pressure of at least 100 lbs. to the square inch. Should the Engineer consider it necessary to excavate the ground from within the Excavation within - 1.1 screw pile and payment screw pile to a greater depth than 12 feet and replace it with concrete the for. same shall be done and payment made therefor at Schedule rates. 258.

The Schedule prices of screw piles placed in the permanent work ^ice to include bolts, are to include all bolts and dowels, also the steel sleeves, diaphragms, packing rings, as well as the disposal without further cost to the Company of any ma- terials displaced by the screw pile which may come into the tunnel. 261. During the process of screw pile driving the tunnel lining shall be dili- boit”tLer“o“nrb‘l gently attended to, maintaining the bolts of the tunnel lining at all times ^neddvin‘^g“"°® tight, and any bolts or bolt holes used temporarily for screw pile driving purposes shall immediately on the completion of such use be restored to proper condition. 262. The concrete troughs surrounding the heads of screw piles shall be concrete troughs, formed with sloped and ragged sides to make a bond for additional concrete, in conformity vvith the dimensions shown on Contract Drawing No. lOOi. 263. The screw pile driving machinery and accompanying tackle shall be p*’® of the best materials and workmanship and of ample strength, and adequately arranged for the rapid placing of the screw piles. Detail plans and specifica- tions of this plant must be submitted for the approval of the Engineer before the plant is made and the construction of same shall be subject to his inspec- tion; such approval by the Engineer shall in no way affect the sole responsi- bility of the Contractor for the adequacy of the plant for the purpose intended. 61 PENNSYLVANIA, NEW JERSEY AND NEW YORK RAILROAD.

Screw piles will be paid for per screw piles of fixed lengths with deductions from or additions to same per lineal foot of screw pile as stated in schedules. 265. Each segment of the tunnel lining shall have a hole near the center for grouting, which hole shall be closed by a screw plug. As soon as the En- gineer considers it practicable after a ring of tunnel lining has been placed and the shield advanced beyond it, the hole shall be opened and grout shall be forced into the surrounding materials by means of a suitable machine which will mix the grout continuously and permit the application of a pressure of 60 pounds per square inch in excess of the external water pressure. Sufficient grout shall be used to fill all voids outside the cast iron lining and to form a shell having an average thickness of 3 inches. Where the tunnel is driven wholly or partly in rock, the grout shall fill all voids between the cast iron lining and undisturbed rock or concrete trough, whatever their extent may be. When the grouting is completed, the plugs shall be replaced and screwed up tight. Plugs will be paid for as part of the tunnel lining. Payment for grouting will be on the basis of cement used at the rates named in the schedules in the con- tract, these rates including sand, labor, plant and all other things required for the completing of the grouting and being in full payment therefor. 266. Tlie Engineer may omit the grouting wherever he considers it unnec- essary, and in such case the contract price for completed tunnel will be reduced by the amount stipulated in the schedules for grouting. 267. It is expected that the concrete lining wdth the conduits for electric wires, etc., will be placed after the removal of air pressure, but if the Engineer considers it necessary in any case, the Contractor shall place it in compressed air as the driving of the tunnel proceeds and as near the working face as the Engineer may require. For such work the Contractor will be paid the price named in the schedule for concrete laid in compressed air and within the cast iron lining of tunnels driven with shields, and such unit price for concrete shall also include the cost of placing electric conduits, ladders and all other things built into the concrete, for which no other payment will be made. Immediately before placing concrete the exposed faces of the cast iron tunnel lining shall be cleaned from mud and dirt. 268. Where screw piles are used the bottom concrete formation of the tunnel is to be sloped so as to lead to the screw pile troughs in the concrete. The cast iron drains are to be laid with a true uniform fall towards the lowest point of tunnel grade and in single lengths between the screw pile troughs. 269. In the cast iron lined tunnels under the River, the Contractor shall place in each tunnel 4 sets of cast steel manhole segments with cast iron plugs suitable for withdrawal, in positions to be pointed out by the Engineer. The Schedule price for these cast steel segments is included in the price for cast steel lining in Schedule.s of contract and the price of the cast 62 PENNSYLVANIA, NEW JERSEY AND NEW YORK RAILROAD. Tunnels Driven With Shields— ( con fenztec?.) iron lining displaced by same will be deducted. The cast iron plugs filling these manholes will be similarly paid for as ordinary cast iron lining of tun- nels. For details of manhole segments see Contract Drawing No. 1018. 270. Whenever required by the Engineer, the Contractor shall remove the removfngalr'^prMsun air pressure in order to test the strength of the work; and if any weakness or break results, the Contractor shall make it good at his own expense and in such manner as the Engineer may direct. 271.

The revolutions of compiessors shall be registered by revolution counters. The pressures in air receivers shall be registered continuously. 276. If in the opinion of the Contractor it becomes advisable, he may at his own expense deposit on the bed of the river or in a channel or channels excavated therein, blankets or masses of clay to reduce leakage of air from the tunnels; but no such measure shall be taken without the previous con- sent of the Secretary of War, and if taken shall be subject to such restrictions and regulations as the Secretary of War may impose. 277. Payment for completed sections of tunnel will be made on progress and final estimates at the rates named in the contract. Payment will also be made on progress estimates for tunnel driven, lined with cast iron and grouted but not lined with concrete, at the prices named in the Schedules of Unit Prices; such partial payment shall in no way relieve the Contractor from his obligation under the contract to complete and maintain the work; the amounts of excavation are calculated by multiplying the area of the cross- section of the tunnel within the exterior surface of the cast iron lining as shown on the Contract Drawings by the length of the lining. No excavation in advance of the completed lining will be estimated, nor will any payment be made for materials brought into the tunnel from outside of the cast iron lining. Tunnels Driven Without Shields. 278. Where tunnels are built of concrete masonry or steel and concrete, the concrete shall be built solidly against the rock, and where brick masonry is used in arches a minimum thickness of four inches of rock packing is to be built outside the same to insure drainage of water where shown on plans and where the Engineer may deem it necessary. 279. In all cases the minimum thickness of masonry lining or combined masonry lining and rock packing will be defined by the Neat Lines shown on Contract Drawings, and will be increased wherever the Engineer may deem it necessary. Such an increase in thickness will cause a corresponding dis- placement outward of the neat lines which in every case define the minimum thickness of masonry or combined masonry and rock packing required. 280. Excavation outside of the neat line must be avoided as far as practi- cable and in rock sections loose or shattered rock must be removed and replaced by masonry or by rock packing, as the Engineer may require. In earth sec- 64 : PENNSYLVANIA, NEW JERSEY AND NEW YORK RAILROAD. Tunnels Driven Without {continued.) tions the excavation must be large enough to permit building masonry to the full required thickness clear of any timber which it may be necessary to build in, and all voids between excavation or timbering and masonry are to be filled in with concrete and grouted up tight; the grouting will be paid for per barrel of cement used. As a fair provision for such contingencies, dea“u1itiou^oc it is assumed, except in cases otherwise specially provided for herein, that the excavation and therefore the concrete and rock packing will extend outside the neat lines to an average line designated Standard Section Line on the Contract Drawings and it is understood that the prices for excavation, concrete and rock packing outside neat lines per lineal foot of tunnels in the schedule are based on measurement of same as defined by the standard section lines previously referred to. No allowance will be made to the Contractor for of°8“tanTai“d*ectioi‘*® excavation removed and replaced by concrete or I'ock packing outside of the standard section line, nor will any deduction be made from either by reason of any material he may not excavate between neat and standard section lines. Where an increased thickness in masonry lining is required by the Engineer, if twckuess of masom-y as above provided, a corresponding displacement of the standard section line will be understood and payment will be made for the increase in the standard section at the prices named in the Schedule of Unit Prices for excavation, masonry, concrete, or rock packing. The standard section lines above referred to will extend to beyond the neat lines of various tunnel sections as follows; 281. In concrete lined tunnels and tunnels with brick arches with and without rock packing the standard section lines will extend an average distance of one foot outside the neat lines on the roof and sides and six inches outside the neat lines in the floor or invert, as per Contract Draw- ings Nos. 1028, 1029, 1033, 1031, 1030, 1037, 1019, 1050, 1051, 1059. 282. Timbering shall be used wherever necessary to support the materials 'Umbering, or to secure the safety of the work or workmen. This will be at the sole ex- pense of the Contractor and included in his contract price, except in cases where by the direction of the Engineer the timber is built into the work. 283. The centering for arched roofs shall be of steel construction and of design approved by the Engineer, and it shall remain in place as long as he may from time to time require. 284. The Contractor shall provide to the appi’oval of the Engineer, electric Lighting, lighting for all parts of the work and plant, including lights for the Resident Engineers’ offices near the shaft and portal and such special lights or groups of lights as the Engineer may require in connection with surveys. Telephone communication shall be established between the tunnels and the offices of the Resident Engineers. The Contractor shall install and operate plant for the Ventilation, purpose of efficiently ventilating the tunnels during construction. 65 PENNSYLVANIA, NEW JERSEY AND NEW YORK RAILROAD. Drain pipes.

Tunnels Driven Without Shields — {continued.) 285. Drain pipes of 4 inches inside diameter shall be built into the con- crete at intervals of not more than 50 feet on each side of the arch and. alter- nated as shown on Contract Drawings. They shall discharge into the snb-floor drains and where shown into the cast iron drain inspection hand-holes built into the sub-floor drains. Tee branches opening against the rock face in re- cesses left in the concrete shall he inserted wherever necessary to drain water bearing fissures. Where the rock carries much water the distance between drains will be reduced as much as necessary to give perfect drainage and to relieve the masonry lining from water pressure. 280. The Contractor for Section K (the Bergen Hill tunnels) shall commence immediately a through heading 10 feet by 8 feet in cross section in each of the tunnels and drive them through with all possible speed from both ends. As soon as the headings are driven through, one of them shall be cleaned out and turned over to the Contractor for Section Cj for use as specified in paragraphs 214 and 300. While one is being used for this purpose the other tunnel shall be completed with its internal lining of concrete and brick and all benches, conduits, drains, etc., and cleaned out; after which the Contractor for Section Gj will vacate the first heading and use the completed tunnel for the disposal of spoil, while the Contractor for Section K finishes the vacated tunnel. The Con- tractor for Section Gj will keep the heading and tunnel through wdiich he passes his spoil free from spoil that may be dropped therein. 287. In the construction of the tunnels in the west face of Bergen Hill and adjoining portals the Contractor, should he consider it to his advantage, may construct such lengths of the tunnels by cut and cover work, subject to the approval of the Engineer; this cut and cover work will be paid for at the rates quoted in the Schedule for Bergen Hill tunnels irrespective of methods of construction. 288. As soon as the two-thirds’ portion of the Weehawken Shaft at grade level is handed over to the Contractor for Section Gj, he shall commence the driving of tunnels eastward from shaft for distances of about 214 and 250 feet, or less distances if the rock proves too unsound to permit driving tunnels with- out compressed air. They shall terminate in enlarged sections (shield chambers) to permit the erection of shields, as shown on Contract Drawdngs Nos. 1028, 1029, 1030, 1031, 1032. Cast Iron Lined Tunnels Driven Without Shields. 289. Cast iron tunnel lining shall be provided in tunnels driven without shields in places where the Engineer may consider it necessary, see Contract Drawing No. 1005. 66 PENNSYLVANIA, NEW JERSEY AND NEW YORK RAILROAD. Cast Iron Lined Tunnels Driven Without Shields — {continued.) 290. Excavation in excess of that required to place the tunnel lining Excavation, must he avoided as far as practicable, but in rock all loose or shattered rock must be removed. Where the excavation is in earth or other materials, the excavation must be large enough to permit placing the cast iron lining clear of such timbering as it may be necessary to build in. As a fair provision for unavoidable excavation outside of the lining, payment will be made for the removal of all material within the “ Standard Section Line.” This line is 9 inches outside of the exterior surface of the cast iron lining. No payment will be made for excavation outside of this line nor deduction for materials left within it, provided no material is left in place which will interfere with placing the cast iron lining. 291. Timbering shall be used wherever necessary to support the materials Timbering, or to secure the safety of the work or workmen. Wherever practicable, it shall be removed before the space between the exterior surface of the tunnel lining and the sides of the excavation is filled in. 292. The space between the tunnel lining and the excavated surface shall be closely packed with concrete. Pipes for grouting shall be inserted in the cast iron lining and concrete wherever the Engineer may require and voids filled by grouting. The volutiie of concrete will be calculated between cast Measurement of iron lining and standard section line, no allowance being made for concrete required to fill spaces outside of the standard section line, or deduction from either excavation or concrete on account of any materials not excavated within said line. Plugs in the tunnel lining and grout will be paid for as pro- vided in paragraph 265. Portals. 293. The portals in Weehawken Shaft and the portals on the w'est face of Bergen Hill shall be built of first-class stone masonry with granite face stone and coping, as shown on Contract Drawings Nos. 1050 and 1058. 291.

For measure- ment of excavation and material see paragraph 294. Waterproofing. 296. In tunnels driven with shields, the cast iron shells will serve as water- proofing. 297. In tunnels driven in the ordinary manner without shields, the space between the sides of the excavation and the neat line shall be filled with con- crete behind suitable forms. After the forms are removed the surface of the concrete shall be given a 1/2 inch coat of mortar containing equal parts, by volume, of Portland cement and sand and troweled smooth. After the mortar has set and dried out, it shall be covered with alternate layers of coal-tar pitch and felt, seven layers of pitch and six of felt. The felt shall be “hydrex” felt manufactured by F. W. Bird & Son of East Walpole, Mass., or felt equally satisfactory to the Engineer. The pitch shall be straight run coal tar pitch which will soften at 60 deg. F., and melt at 100 deg. F., being a grade in which distillate oils, distilled therefrom, shall have a specific gravity of 1.105. The pitch shall be mopped on the surface of the concrete to a uni- form thickness of not less than 1/16 inch. Immediately on this coat of pitch and while it is still melted, there shall be laid a covering of felt previously mopped with pitch on the surface to be applied, the sheets to lap not less than 4 inches on cross joints nor less than 12 inches on longitudinal joints, and to be made to adhere firmly to the pitch-covered surface of the concrete every- where. This felt layer shall be mopped with pitch as above specified, another layer of felt mopped with pitch and then added and the process continued to the full number of layers required. This waterproofing shall extend from the level of the bottom of the electric ducts to 15 degrees above the spring line of the roof arch. After the waterproofing has been placed the remainder of the concrete with the electric ducts, etc., shall be placed. 298. Where roofs of tunnels driven in the ordinary manner without shields are of bi’ick, they shall be plastered with a mastic containing coal tar and Portland cement in such proportions as the Engineer may from time to time require. This shall be applied with a trowel in a uniform layer 1/2 inch in thickness. This waterproof coating shall then be covered with one course of brick laid on flat in a bed of mortar 1/2 inch thick, containing equal parts by volume of Portland cement and sand, and the joints completely filled with mortar of the same composition. The junction between the waterproofing in the roofs and sides shall be formed so as to make a continuous waterproofing surface. 68 PENNSYLVANIA, NEW JERSEY AND NEW YORK RAILROAD. W ATERPROOFING— (conh'wMecZ. ) 299. Where the roofs of tunnels are of concrete built solidly against the bum rock, the waterproofing of the roof shall consist of grout injected through pipes built into the concrete at such intervals as the Engineer may require. 300. Where tunnels are built by the cut and cover method, the sides, if in rock excavation, shall be waterproofed as described in paragraph 297 ; if in earth excavation, they shall be waterproofed as herein specified for roof. The roofs of tunnels shall be plastered smooth and covered with coal tar and felt as Tunnel roofs, specified for sides of tunnels in paragraph 297. The waterproofing shall be covered with a 1 inch layer of mortar, containing equal parts, by volume, of Portland cement and sand. The mortar shall be laid on in areas about 5 feet square and when one square is set, the adjacent ones shall be laid tight to it, this laying out in squares being for the purpose of relieving expansion or con- traction. A thorough connection shall be made between the waterproofing of the top and sides. 301. The waterproofing of retaining walls and portals shall extend from Retaimngwaiu and the base of the wall to within one foot of the top. Where the walls are built against the face of rock excavation, the waterproofing shall conform to the requirements for sides of tunnels in paragraph 297; where the wall is not built against a rock face, the waterproofing shall be the same as specified for tunnel roofs in paragraph 300. 302. No waterproofing will be used in the floors except where specially noors m tunnels, required by the Engineer, and will then be paid for at the rates named in the Schedules of Unit Prices. 303. W^aterproofing and the protecting mortar coat must be protected from proog'^ng “ injury by working or walking thereon, or during the filling of rock packing over tunnel roofs, or while placing back filling behind retaining walls.

At the end of another period of six months, if the costs of like maintenance shall have been paid by the Contractor, the remaining one-half of the retained percentage shall he paid to him, and the Contractor expressly agrees that the Company may maintain, at the Contractor’s own proper cost and expense during their continuous use for public traffic, the works in perfect condition for such period of twelve months after such certified completion of the works, but no portion of the said retained ten per cent, shall be paid or considered due the Contractor until he shall have shown to the satisfaction of the Engineer that the work is free from all liens, claims and demands for labor, materials and sujiplies, as hereinbefore provided. 21. If the Company at any time fail to make a monthly payment at the time hereinbefore specified, such failure shall not be held or deemed to vitiate or avoid this contract, but in such case the Contractor shall be entitled to interest at the rate of ten per cent, per annum on the amount unpaid until payment shall have been made, and the Contractor shall have the right to stop all work until so paid; and in that case the date for the completion of the work shall be deferred by a period ecpial to the [)eriod of such stoppage. 25 .

No payment shall in anywise lessen the responsibility of the Contractor for the full and final completion of the entire work; neither shall it exempt said Contractor from liability, at his own cost and expense, to replace the work if afterwards found to have been done ill or not done according to the plans and specifications of this contract, either in work done or in materials furnished. 27. The said Contractor agrees to protect and hold harmless said Company and all of its property from any and all kinds of liens accruing to or to accrue for labor and services performed and for materials and supplies furnished or for any of the same, in or about the work and construction herein provided for. 28.

Should there be any unsatisfied claims for deaths, 113 PENNSYLVANIA, NEW JERSEY AND NEW YORK RAILROAD. personal injuries or damages to persons or property at the time when the final estimate for the work is made and returned, the Engineer shall have the right to retain out of said final estimate a sum in his judgment sufficient to protect the Company in regard to all unsatisfied claims as aforesaid; and in case the amount thus retained from the Contractor on said final estimate should be insufficient to pay the amount of such claim when adjudicated, the Company may sue for and recover from the Contractor the amount or bal- ance, as the case may be, as a debt from the Contractor to the Company. 29. The Company will secure right of way where the line passes under pri- vate property and will place the Contractor in possession of the land desig- nated on Contract Drawings Nos. 1001, 1027 and 1044, as sites for shafts and plants, but if delayed by legal injunction or otherwise, the Company shall not be held liable to the Contractor for damages or loss resulting from such delays; hut the Contractor shall be entitled to such extension of time for the comple- tion of work under this contract as the Engineer may certify to be just and equitable. 30. The Contractor shall obtain all permits required from the City or other governmental authorities and shall be solely responsible for penalties incurred and imposed for violation of any laws or ordinances of the City or other Gov- ernments. 31. The Contractor shall be solely responsible for all royalties or other sums payable for the use of patented inventions and shall keep the Company indem- nified against all claims and demands in respect to the use or infringement of any inventions, whether the specifications require such to be used or not. 32. The plant and every jjart thereof and all and every material and thing to be used in or for the construction or maintenance of the work shall, as soon as i>laced upon any land or premises belonging to the Company, or upon any land or premises temporarily held or retained or fenced in during the construc- tion of the wmrk in connection with the same, absolutely be and become the property of the Company and shall not be removed therefrom without the written permission of the Engineer being first obtained. When and so soon as the work comprised in this contract and specifications is ready to be o))ened for public traffic and all the obligations of the Contractor to the Company are fulfilled and when the release in full by the Company to the Contractor shall have been executed, and not before, the Company will give and deliver to the Contractor, for his own use and benefit, all the plant and surplus materials 134 PENNSYLVANIA, NEW JERSEY AND NEW YORK RAILROAD. placed by the Contractor and then remaining upon the work or upon the land or premises temporarily held as aforesaid which the Engineer shall in writing certify are not required for the permanent purposes of the work, and the Con- tractor shall immediately remove and take away the same, leaving the work and premises in perfect repair, clean and in good condition, all at his own cost and expense. 33. It is distinctly understood and agreed between the parties hereto, any- thing herein to the contrary notwithstanding, that if for any cause the work to he done hereunder by the Contractor, or any part thereof, shall be impeded or delayed by the order of any court in any proceeding at law or in equity now pending or hereafter to be brought, there shall be no right on the part of the Contractor to demand or recover any damages or to receive any additional compensation from the Company, on account of such impediment or delay; but that any loss or damage caused by such impediment or delay shall be borne exclusively by the Contractor and the Company shall not be responsible in any way therefor. It is further understood and agreed, however, that in case the w’ork or any part thereof shall be impeded or delayed as aforesaid, then the time within which the Contractor is required hereunder to complete the work, or any part thereof, so impeded or delayed, shall be extended for an additional period equal to that for which the same shall have been so impeded or delayed. 34. In case the Contractor shall fail to complete the work hereunder in accordance with the specifications and to the satisfaction of the Engineer within the time herein agreed upon, the Contractor shall and will pay to the Company a sum equal to 1/50 of 1 per cent, of the amount paid or to be paid him for the entire work, for each and every day the time consumed in said work and com- pletion may exceed the time herein allowed for that purpose, which said sum in view of the difficulty of ascertaining the loss which the Company will suffer by reason of delay in the performance of the work hereunder, is hereby agreed upon, fixed and determined by the parties hereto as the liquidated damages that the Company will suffer by reason of said delay and default and not as a penalty; and the Company shall and may deduct and retain the amount of such liquidated damages out of the moneys which may he due or become due to the Contractor under this agreement. 35. It is further agreed that if the Engineer shall at any time certify that in his opinion sufficient and suitable machinery, tools, plant and materials are not provided or that a sufficient number of workmen are not employed in the execution of the work under this contract, or that the work or any part thereof 115 PENNSYLVANIA, NEW JERSEY AND NEW YORK RAILROAD. is not being carried on with due diligence and dispatch to ensure its completion within the time specified in the contract, or if the Contractor shah not comply with such orders as may from time to time he given by the Engineer with respect to the work, the Company may give the Contractor written notice re- quiring him to provide such additional machinery, tools, plant or materials, or to employ such additional number of workmen as the Engineer shall think reasonable for the due execution of the work with greater diligence and dis- patch, or to comply with such orders as aforesaid, and if the Contractor shall not within 10 days next ensuing after the receipt of such notice comply in all respects with the directions thereof, or commence the things thereby I’equired to be done and diligently proceed therewith, so far as time will admit, the Company may: (1) Declare the Contractor to be in default; and the Company in addition to every, or in substitution for any other remedy which it may have by law or hereunder, may thereupon forthwith procure by contract or otherwise either for the Contractor, for his account and at his risk or otherwise as the Company shall determine, the completion of the work embraced in the con- tract, or, in any case where the Company so elects, the construction or pro- vision of any part of such work; and the Company may to the extent of the cost of such completion of the work embraced in the contract or of such con- struction or provision of any part thereof and interest on such cost, withhold and apply thereon any moneys otherwise due or to become due by the Company to the Contractor, and the Contractor shall be liable to the Company and shall as the Company may from time to time require, forthwith pay to the Com- pany the excess, if any, of the cost to the Company of the completion of such construction of the work embraced in this contract or of such construction or provision of any part thereof over the amount payable to the Contractor there- for under the terms of the contract. And such completion, performance or provision by the Company shall not release or discharge the Contractor from liability with respect to his paying the costs of maintenance of the work after completion as herein stipulated, or the remainder of the construction, or any other liability hereunder, or (2) Declare this contract at an end except as to liability of the Contractor hereinafter in this paragraph provided, and may make a new contract for con- struction with other parties, upon such terms as the Company may deem proper; the same to provide among other things that the new contractor shall allow for so much of construction as has been already completed, a reasonable IIG PENNSYLVANIA, NEW JERSEY AND NEW YORK RAILROAD. amount to be prescribed in such new contract or to be ascertained as in such new contract to be provided; and in such case the Contractor shall pay the Com- pany for all damages which the Company shall sustain by reason of such failure, including the excess, if any, of the amount which the Company shall pay the new contractor over the amount it would have had to pay the Contractor, party hereto, for the same work and materials, together with the amount, if any, which shall be due the Company by reason of the delay in completion of the construction and completion of the entire work, and (3) The Company may also proceed, as to the Company may seem proper, upon the bond given by the Contractor for the due performance of this con- tract, and (4) The Company may also bring any suit or proceeding for injunction or to recover damages or to obtain any relief or for any purpose proper under this contract. 36. The Contractor hereby agrees to file with the Secretary of the Com- pany, within 10 days from the date of this contract, a penal bond in the sum of dollars ($ )with good and sufficient sureties thereon, satisfactory to the Company, conditional for the faithful performance of this contract; should the Contractor fail to do so, this contract may be cancelled at the option of the Company.
