The inspector representing the City Engineer shall have free entry, at all times while work on the contract is being performed, to all parts of any mill, shop or factory where material herein specified is being produced. The Contractor shall afford the inspector, free of cost, all reasonable facilities to satisfy him that the material is being furnished in accordance with these specifications. Tests will be made at the place of manufacture prior to shipment whenever practicable, and will be so conducted as not to interfere unnecessarily with the operation of the works. The City of Seattle shall have the right to make chemical and physical tests of materials in tlu laboratory of the City Engineer’s Department in Seattle, and to reject material, either finished or unfinished, which does not conform to the specifications. Any material which shows injurious defects subsequent to its acceptance at the place of manufacture will be rejected.
CEMENT.
The cement shall be a true Portland cement, of the best quality, dry and free from lumps and all foreign matter. It shall be a brand known to the City Engineer to possess the proper qualifications and uniformity for the work intended. It shall be packed at the place of manufacture in canvas sacks, each plainly marked with the manufacturer’s brand. It shall be delivered on the work, in the original package and in good condition, in advance of its use, in such quantity as to afford the City Engineer ample time and opportunity to conduct tests.	t
(a)	Volume of Barrel. For the purposes of measurement in proportioning concrete,
three hundred and seventy-six (376) pounds net of cement shall be considered to be one barrel.	<
(b)	Tests. Cement shall be subject to the following requirements:
At least eighty-five per cent (85%) shall pass a No. 200 screen and not less than ninety-four per cent (94%) shall pass a No. 100 screen. Briquettes made of one (1) part cement, three (3) parts standard Ottawa sand by weight, after one (1) day in moist air and six (6) days in clear water, shall show a tensile strength of not less than two hundred and fifty (250) pounds per square inch, and after one (1) day in moist air and twenty-seven (27) days’ immersion in water, not less than three hundred fifty (350) pounds per square inch.
Pats about three (3) or four (4) inches in diameter, and about one-half (i/^) inch thick in the center and tapering to a thin edge, will be made from neat cement paste of normal consistency, and placed upon a clean glass plate about four (4) inches square. These pats will be kept in a moist atmosphere for twenty-four (24) hours and then exposed in an atmosphere of steam above boiling water in a loosely closed vessel for five (5) hours, at the expiration of which time they shall be firm and hard and show no signs of cracking, distortion or disintegration. Cement which does not meet the above requirements will be rejected.
In addition to the tests hereinabove specified, all cement shall be subject to such other tests as may be necessary to determine whether it possesses the proper qualifications for use on this contract. Should any objectionable qualities be found at any time in any cement used, or offered for use, or should any cement fail to produce good concrete or mortar, its use will be prohibited, regardless of the fact that it may have satisfactorily passed the above tests.
AGGREGATE.
Aggregate for mixing concrete shall be sand and gravel secured from deposits which consist of fragments of sound hard rock only. Material which contains soft pebbles or grains, or which will disintegrate on exposure to the air or which, is stained with iron rust, will be rejected. It shall be washed until clean and free from soft particles, lumps of28
Cedab River Water Supply
clay, vegetable loam, and all other organic matter. Aggregate shall be separated by screening into sand, or fine aggregate and gravel, or coarse aggregate, as follows:
Sand, or fine aggregate, shall be composed of grains varying uniformly in size from fine to coarse, not less than twenty per cent (20%) nor more than forty (40%) shall pass a No. 30 screen, one hundred per cent (100%) shall pass a No. 4 screen. For sand to be used in making mortar, one hundred per cent (100%) shall pass a No. 6 screen.
Gravel, or coarse aggregate, shall be composed of grains and pebbles varying in size from those which will just pass a two and one-half inch (2Y^') mesh screen and be retained on a two-inch (2") mesh screen, to those which will just pass a one-fourtli inch (%") mesh screen and be retained on a No. 4 screen.
CONCRETE.
Concrete shall be composed of one part, by volume, of cement to a total of eight parts by volume of sand and gravel, each measured separately. The City Engineer will make frequent mechanical analyses of the aggregate furnished by the Contractor and the proportions of sand and gravel will be varied from time to time as may be necessary to produce concrete of the greatest possible density. For example—one part cement, three parts of sand and five parts of gravel; or one part cement, two and one-half parts of sand and five and one-half parts of gravel, etc. In proportioning concrete mixtures, a barrel of cement, weighing not less than three hundred seventy-six pounds (376 lbs.) net, will be taken as measuring three and one-half cubic feet.
Concrete shall be mixed in “batch” mixers of a type approved by the City Engineer. The use of so-called “continuous,” “gravity” or “pneumatic” mixers will not be approved. The mixing shall be in batches of the sizes directed, and shall be thorough and continued for not less than one (1) minute and until every particle of coarse aggregate is covered with a mortar of cement and fine aggregate.
The materials to be mixed shall be separately measured, before being placed in the mixer, in boxes of proper size to secure the desired proportions, or by some method which will secure exact results. Measuring devices which depend for their operation upon the flow of materials from hoppers, or other approximate methods will not be allowed. Clean water shall be used in mixing concrete; it shall be introduced into the mixer in such quantity only as is necessary to thoroughly hydrate the cement and to produce a mass of quaking consistency, and such that the concrete produced shall be dense and impervious. Means shall be provided to measure and control the amount of water which is used in each batch of concrete, the measuring device to be so constructed that the amount of water used may be readily changed, if necessary, during the progress of the work.
FORMS.
The Contractor shall provide and maintain in good condition all necessary forms, molds and centers for shaping concrete. Forms and centers shall be true to the required shapes and sizes, strong enough to withstand all operations incidental to placing the concrete, water tight, and the faces against which the concrete is to be placed shall be satisfactorily smooth and clean. The lumber used in forms for exposed faces shall be seasoned stock. To obtain tightness caulking with oakum, or other suitable material, may be required, for which the Contractor shall provide suitable tools and materials.
PLACING CONCRETE.	\
Concrete shall be deposited in place in batches of suitable sizes for the various parts of the work. It shall be transported from the mixing plant to the work and deposited before initial set has taken place. Care shall be taken to transport and deposit concrete in such a manner as not to cause segregation of the aggregates. Concrete shall be so poured into and about the forms as to completely fill them. It shall be carefully and thoroughly spaded and rammed into place and all air and surplus water removed. Concrete shall be so deposited as to maintain a nearly level surface and prevent flowing along the forms. Care shall be used to prevent the formation of laitance and where it does form, it shall be removed before further depositing of concrete.Swan Lake Dams

will be the actual number of cubic yards of surface soil removed from dam sites and borrow pits and deposited in spoil banks, measurements being made in cut only.
(b)	Cut Off Trench. A cut off trench shall be excavated on the center line of the dams; its dimensions are shown on the detail plans. The cut off trench shall be excavated to a depth of about three feet in the solid hardpan and shall be refilled with impervious material which shall be solidly rolled if the dam is constructed as a rolled embankment, or filled with selected fine material as specified for the center pool if the dam is constructed by hydraulic methods. Special care shall be taken to compact the earth on the edges of the cut off trench and to secure close contact with the hardpan sides and to prevent the percolation of water through or along the filled trench. The cut off trench has been excavated through the alluvial deposit at the Dam at Inlet and refilled with clay, as noted on the plans, and this construction is not included as a part of this contract.
Payment will be made for excavating the cut off trench at the rate bid for “Trench Excavation” per cubic yard. The amount of excavation so paid for will be the actual number of cubic yards of earth excavated from the trench, measurement being made in cut only. The price bid shall include the cost of excavating the trench through any material which may be encountered, and the final disposal of the material excavated, but shall not include refilling the trench, which will be included in the quantities estimated as Rolled Embankment, or as Hydraulic Fill Embankment.
(c)	Rolled Embankments. Borrow pits shall be opened adjacent to and south of the Dam at Outlet and north of the Dam at Inlet. The dams shall be constructed of the material locally known as “hardpan,” and no earth containing vegetable or other perishable material shall be used. Earth from the cut off trench shown on the plans may be used in the rolled embankment if of proper quality. All rocks and stones which are large enough to prevent the proper spreading or compacting of the earth shall be removed. The earth shall be spread in layers of not more than six inches thickness and each layer shall be thoroughly compacted by rolling with a roller which shall be equal in effectiveness to a standard twelve-ton steam road roller having a grooved front roll. The roller shall be passed not less than four times over the entire area of each six-inch layer of earth and rolling shall be continued until the layer is thoroughly compacted. No earth shall be dumped in or upon mud and all soft and muddy earth shall be removed.
Rolled Embankments will be paid for at the rate bid therefor per cubic yard. The price bid shall include excavating the material in the borrow pits, transporting and depositing in the embankments, spreading and rolling, draining and maintaining excavations and embankments, all powder, timbering, labor, supervision, tools and appliances, and executing the work as specified.
The number of cubic yards of earth paid for as Rolled Embankment will be the actual number of cubic yards of earth excavated from the borrow pits and deposited and rolled to form the permanent dams. Measurements for estimating the amount of earth so deposited will be made in cut only, and no allowance will be made for shrinkage due to rolling and compacting.
(d)	Hydraulic Fill Embankment. Earth for the construction of the Dam at Outlet shall be secured from borrow pits opened on the hill above the east end of the dam, for the Dam at Inlet a borrow pit shall be opened on the hill south and west of the south end of the dam. The dams shall be constructed of the material locally known as “hardpan” with such a mixture of sand and clay as may be necessary to produce the densest and most stable structures, and no earth containing vegetable or other perishable material shall be used. The dams shall be constructed by the “center pool” method, the coarser particles of earth being deposited on the slopes of the embankmets in ridges between which the center pool containing the water and “fines” shall be maintained. Provision shall be made to drain the water from the center pool and to maintain such a mixture of earth and water therein as the City Engineer may direct. The City Engineer will make determinations of the size of soil grains in the borrow pits and in the center pool of the dams and the Contractor will be required to borrow from those portions of the pits which will produce material of proper grade for building the slopes and cores of the dams and to maintainSwan Lake Dams
31
the center pool of such dimensions as may be necessary to produce impervious cores in the dams. Great care shall be taken to prevent the segregation of the material into layers of varying sizes of soil particles and the material in the center pool shall be spaded and kneaded, if necessary, in order to prevent such segregation and to maintain a uniform mixture. The flumes, or pipes, which carry the sluiced earth from the borrow pits to the dams, shall be carried along each side of the dams and provision shall be made for introducing the sluiced earth into the center pool of the dam under construction on either or both sides and at any point on the flume or pipe line. The Contractor shall conduct the sluiced earth into the center pool in a uniform and systematic manner and so as to produce an embankment of uniform structure. The accumulation of stones and clods or chunks of earth in piles at the point of discharge from the flumes and pipe lines shall be prevented.
Hydraulic Fill Embankment will be paid for at the rate bid therefor per cubic yard. The price bid shall include excavating the material in the borrow pits, transporting and depositing the material in the embankments, all powder, timbering, labor, supervision, pipes, flumes, tools and appliances, all electric current and water and executing the work as specified. The number of cubic yards of earth paid for as Hydraulic Fill Embankment will be the actual number of cubic yards of earth sluiced from the borrow pits and deposited in the permanent dams. Measurements for	the	purposes of estimating the	amount
of earth so deposited will be made in cut	only, and	no	allowance will be made for	shrink-
age due to the water settling and compacting of the earth.
USE OF WATER AND ELECTRIC CURRENT.
Water for sluicing at the Dam at Outlet shall be pumped from Swan Lake, for sluicing at the Dam at Intake water may be pumped from Swan Lake or from the Cedar River Pipe Lines which cross the south end of the dam site. If water is taken from the pipe lines the Contractor will be required to erect a tank, or excavate a pit, into which the water will flow and to which his pump connections shall be connected; pumping directly from the pipe lines will not be permitted. Water taken from the Cedar River Pipe Lines for sluicing will be charged to the Contractor at the rate of $30.00 per million gallons.
Electrical energy will be furnished the Contractor for operating pumps for sluicing from the power lines which pass Swan Lake. Transformers will be placed near the site of the Dam at Intake and a transmission line will be extended to the Dam at Outlet. Current will be furnished in any amount	from 300	to	400 kilowatts, and will be	charged
to the Contractor at the rate of one cent	per kilowatt	hour. In comparing bids	on con-
structing the dams by hydraulic methods with bids for their construction by spreading and rolling the cost of constructing the transmission line to the Dam at Outlet will be estimated to be $5,000.00.
RIP RAP.
All stones or rocks which are developed in the borrow pits opened for the construction of the dams, and which are suitable for the purpose, shall be placed on the water surface of the dams as rip rap. The quantity of material which will be available for this purpose is not possible of determination in advance and rip rap shall be placed only in such quantity as may be secured from the borrow pits without making special excavations therefor. Rip rap shall be twelve inches in thickness. The Contractor will not be required to place the separate stones by hand, but the rip rap shall be trimmed approximately to surface.	»
Rip rap will be paid for at the rate bid therefor per cubic yard in place, the price bid shall include transporting the stones from the borrow pits and placing them on the slopes of the dams as specified. The amount of rip rap paid for will be the actual number of cubic yards placed on the slopes of the dams.

Date of first publication in the Daily Journal of Commerce, Seattle, November 15, 1920.	(C-1061)TO START SWAN LAKE DAMS ON! FIRST OF YEAR
Calls For Bids to Be Made As Soon As Plans Are Approved
Will Be Followed By Con-j struction of 12,000
!
Foot Tunnel
Following the approval of the Board of Public Works of the plans for the two proposed earth dams at Swan Lake, necessary to hold the waters of this huge impounding basin, Assistant Supt. of Water John Lamb, reports that bids on this work will likely be called about the first of the year. Following the completion of these dams the building of the 12.000 feet of eight foot concrete tunnel from the outlet of Swan Lake to the building housing the controlling works, gates and screens at Molasses Creek will be undertaken. Plans for this portion of the work have been completed, as well as plans for the controlling works structure, a concrete building 80x80 feet in size. Eventually four large pipes will lead from the controlling works to the city. The two 60-inch wood stave pipes	now	serving the	city will	ter-
minate at the Molasses Creek controlling works and pipe line No. 3, a 66-inch steel pipe will be added. Provision for the future connection of another 66-inch steel line will be made.
This scheme will then involve the 8-foot concrete tunnel 12,000 feet in length, which will bring the water from the big Swan Lake impounding basin to the controlling works and from	this	unit four main lines	will
lead to Seattle. Should trouble occur along any of these lines the load could be transferred to other lines, and no interruption to service- be felt as would now be the case should one of the present lines give way.
The condition of the bond market is all that has prevented the start of work on the new pipe line, but it is now thought that by the time the new dams	are	completed	bids on	the
pipe, tunnel work, construction of the controlling	works and	building	and
other work necessary to safeguard the city’s water supply may be called. The building of the new pipe line is figured to cost $3,000,000.University of Washington Library
