provided that the said members or details are similar to those used on the work, and provided that the total cost to the Contractor of such extra tests does not exceed one quarter of one per cent (0.25%) of the total contract price of the work.

WORKMANSHIP.

All metal shall be carefully straightened before being turned over to the shops.

All workmanship shall be first-class in every particular, and all portions of metal-work exposed to view shall be neatly finished.

All idle corners of plates and angles, such for instance as the ends of the unconnected legs of angle lacing, shall be neatly chamfered off at an angle of about forty-five (45) degrees, so as to give a sightly finish to the work and to avoid bending of said corners during shipment and erection.

As far as practicable, all parts shall be so constructed as to be accessible for inspection and painting.

All punched work shall be so accurately done that, after the various component pieces are assembled and before the reaming is commenced, forty (40) per cent of the holes can be entered easily by a rod of a diameter one sixteenth of an inch less than that of the punched holes; eighty (80) per cent by a rod of a diameter one eighth (1/8) of an inch less than same; and one hundred (100) per cent by a rod of a diameter one quarter (1/4) of an inch less than same. Any shopwork not coming up to this requirement will be subject to rejection by the inspector.

SHEARED EDGES.

All sheared and hot-cut edges shall have not less than one quarter (1/4) inch of metal removed by planing to a smooth, finished surface. Lacing-bars, fillers, stay-plates, and stringer-bracing connecting plates only will, be exempt from this requirement.

RE-ENTRANT CORNERS.

No sharp or unfilleted re-entrant corners will be allowed anywhere in the work.
