Rolling shall continue until the subgrade is uniformly compacted,
brought to a true shape and to an elevation uniformly eight (8) inches
below the established grade and cross sectional contour of the top of
the pavement. 'There the soil in the alley consists of sand or sandy
soil incapable of compaction by rolling or tamping, said compaction
shall be accomplished by thoroughly flooding the subgrade. After
being prepared in the above manner the subgrade shall be so maintained
until the pavement has been placed thereon.
CHECKING AND ACCEPTANCE: Immediately before the pavement is laid,
the subgrade shall be..checked by means of an.approved template, shaped
on the under side to conform to the lower surface of the finished pave-
ment, or by a method of testing approved by the Board of Local Improve-
ments. All high places shall be removed to true grade and any low places
filled with sandy soil and rolled or hand tamped until smooth and firm,.
The subgrade shall be checked and completed in accordance with these re-
quirements for a distance of not less than one hundred (100) feet in
advance of the pavement. If hauling over the subgrade after it has been
finished and checked as specified results in ruts or other such ob-
jectionable irregularities, the contractor shall reroll or hand tamp
the subgrade and place it in smooth and satisfactory condition before
the pavement is deposited upon it. If the condition of the subgrade is
such that it cannot be placed in satisfactory condition to receive the
pavement, paving shall be stopped by the Engineer unless the contractor
provides and hauls over suitable trackways or uses other means for the
protection and maintenance of the subgrade. The cost of subgrade pre-
paration and all excavation and replacement required by these specificat-
ions shall be included in the unit price bid for Special Excavaticn.

• MCXING AND PLACING CONCRETE: Concrete shall be mixed and placed
in accordance with the requirements of Section 408 of the "Standard
Specifications", insofar as the same may apply. While being placed the
concrete shall be vigorously vibrated, by the use of a mechanical
vibrating device, and spaded to eliminate voids or honeycomb pockets..
The concrete shall be especially well spaded and tamped against forms
and bulkheads. The concrete shall be struck off, so that the upper
surface shall conform to and be sufficiently higher than the contour.
herein specified for the upper surface of the finished pavement, to
give the specified thickness of pavement herein required. The strike
board shall be moved forward with a combined longitudinal and transverse
motion, and so manipulated as to tamp the concrete thoroughly. A
slight excess of material shall be kept in front of the cutting edge
at all times. The entire area of the pavement shall be struck off and
tamped, so executed as to insure maximum compaction.
FINISHING CONCRETE: After the vibrating and the tamping has been
completed, the pavement shall be rubbed smooth of all ridges and de-
pressions and brought to a true and even surface by the use of wooden
floats. A split float, shaped on the under side to conform to the
contour of the pavement, shall be used for finishing the concrete on
both sides of the longitudinal joints, hereinbefore specified. The
edges adjoining the transverse expansion joint and the form, shall be
tooled with an edging tool, having a radius of one -quarter (k) inch.
After the floating has been completed, the surface of the pavement
shall be tested with a notched straight edge, ten (10) feet in length..
• This straight edge shall be placed over the transverse joints and be-
tween the same at frequent intervals, parallel to the center line of
the pavement and moved across from side to side. Any variation in
excess of one -eighth (1/8) inch above or below the general established
contour of the pavement shall be rubbed with a long handled float and
the irregularities corrected until the straight edge shall show a
bearing for its entire length.
Workmen shall not walk on freshly laid concrete and no one shall
be allowed on the concrete after it has been worked into form and shape
until it has entirely hardened. The entire surfacing of the concrete
pavement shall be done from a bridge, not less than one (1) foot in
width which shall not come in contact with the concrete pavement at
any point. Two (2) of said bridges shall be provided for each concrete
mixing gang. Two bridges shall be maintained in constant readiness to
be immediately moved into position, to provide access for finishing,
tooling and edging joints, adjusting filler and refinishing damaged
portions of the finished surface.
PROTECTION AND CURING: Protection and curing shall comply with
the requirements of Section 408 of the "Standard Specifications".

the pavement herein provided to be constructed, storm sewers of clay
sewer pipe or concrete sewer pipe shall be laid as hereinafter
specified.
Said sewers shall be laid in open trenches in the ground in such
manner as to conform to the elevations, lines and grades hereinafter
specified in accordance with the requirements of Section 603 of the
"Standard Specifications," and shall be designated as Storm Sewers,
Type 3.
The pipe used in the construction of said sewers shall be of the
type known as "Bell and Spigot" having an internal diameter of 8
inches. Where required for connections from catch basins or manhole
catch basins, 811 "Y" branch shall be furnished and set in said sewer.
The material excavated shall be kept compactly along the sides of
the trenches and shall be backfilled as soon as practicable in order to
occasion the least possible inconvenience to the public in the use of
the street or alley as the case may be, but prior to said backfilling
and immediately after the laying of the pipes, bank sand shall be
carefully packed under, around and over the pipes in such manner as
to compactly fill the trenches to a depth of twelve (12) inches above
the top -of the pipes. Where material excavated is not such as can be
readily compacted in said trenches, same shall be replaced with bank
sand, as directed by the Engineer.
The open and unconnected ends of said sewers shall each be securely
closed with a salt glazed, vitrified tile disc and sealed in the manner
specified for joints between pipes.
BASIS OF PAYMENT; This work will be paid for at the contract unit
price per pineal foot for Storm Sewer, Type 3, of the diameters
specified, measured in place, which prices will be payment in full
