I further find that the contractors have placed one wooden brace and two iron braces as designated in the specifications. The wooden brace is constructed of two pieces of good, clear, squared lumber 6 by 8 inches in cross section, well bolted together, secured by plates of boiler iron three-eighths of an inch thick and 14 by 18 inches square. The specifications provide for this brace to run from the south side of the south wall through the center room with a plate on each side of the south wall and one on each side of the wall on the north side of the center room. The contractors have deviated from these requirements in having extended the said brace through the entire length of the building and placed the plates that were specified for the north wall of the center room on the respective sides of the extreme north wall of the building. While this deviation adds nothing to the security of the south wall, it is doubtless as effective as it would have been had it been placed as contemplated in the plan. It may in some degree strengthen the north wall, and I recommend that it be accepted as in compliance with the terms of the contract. The two iron rods called for in the specifications are of wrought iron 11/2 inches in diameter, secured by boiler-iron plates three-eighths of an inch thick and 12 inches in diameter, securely fastened as required in the specifications. There was a necessary deviation from the plan as to the place the rod nearest the east side of the building should be placed. Early in the prosecution of the work a portion of the debris in contact with the eastern wall was removed. During the night following this a section of the south end of the east wall fell, carrying with it that portion of the wall between the south and east rooms to which the plan required said rod to be attached. In consequence the contractors placed the rod so as to connect it with the portion of the wall still intact. As a brace to the south wall it is placed advantageously. In excavation, underpinning, and filling in the contractors have exceeded the limitations prescribed in the contract, and have therefore performed an amount of work for the remuneration of which there is no provision. The following table shows the amount of work authorized in each of the four items with reference to which the contract was drawn and the amount actually performed by contractors:
