AFFIDAVIT OF CONTRACTORS

II. PLANS AND SPECIFICATIONS FOR THE PRESERVATION OF THE CASA GRANDE RUIN, ARIZONA, 1891

(Attached to and forming part of contract)

GENERAL REQUIREMENTS

All the work upon this ruin is to be carried out in such a manner as to interfere as little as possible with the present condition and appearance of the building, and the contractors will be held responsible for any injury to it.

The work is to be carried on under a supervisor, acting for the United States, who shall have power to reject any materials it is proposed to use in the work which are not in his judgment equal to those specified, and he shall have power to have torn down any work done which he has reason to suspect is not such as required by the specifications, but if such work shall prove upon inspection to have been well done the contractor may make a charge of the amount which would have been allowed for that part of the work had it passed inspection.

When the work is completed it must pass the final inspection of the supervisor, or such person as the Secretary of the Interior may designate for the purpose.

1. CLEARING OUT THE DÉBRIS

The débris now filling up the interior is to be removed down to the floor level, or the original ground level. The débris covering an area measuring 10 feet from the exterior walls of the building in every direction is also to be removed. This work is to be carried on in conjunction with the underpinning of the walls, and is to be dependent upon the progress of the latter, the work being done as required by the person holding the contract for the underpinning. All proper precautions must be observed during the progress of the work to prevent any injury to the building, the walls being properly braced and supported before excavation is commenced. The contractor will be held responsible for any injury to the building. Any objects found of archeologic or other value properly belong to the United States and must be deposited in the National Museum. The material removed from the building and from the area about it is to be removed to a proper distance, not less than 100 yards from the building. Proper drainage channels must be provided to keep the excavated area permanently clear of water.

2. UNDERPINNING WALLS

The walls where eroded at the ground level are to be underpinned with hard-burned brick, laid in good cement mortar and extending to a depth of at least 12 inches below the original ground level. This work must be carried on gradually and very carefully in conjunction with the clearing out of the débris. The under surfaces of the overhanging walls must be carefully trimmed to afford solid horizontal bearings against the brickwork. The face of the brickwork is to be set back at least 1 inch and not more than 2 inches from the face of the wall, and the brickwork is to be plastered with a coating of cement mortar, 1 to 2 inches thick, bringing it out flush with the outer wall.

3. FILLING IN OPENINGS

The broken-out lintels of openings are to be replaced by wooden lintels composed of squared lumber, 2 by 4 inches in size, laid side by side across nearly the whole thickness of the walls, with not more than 1 inch space between the boards, and of the same length as the original lintels. The broken-out walls are to be trimmed to afford solid resting places for the new lintels, which are to occupy the same horizontal planes that the old ones did. The openings above the lintels are to be filled in in the same manner as the underpinning previously described, the tinder wall surfaces being carefully dressed to afford solid horizontal bearings, the brick work being set back 1 inch from the wall surfaces and plastered with a coating of cement mortar to bring it out flush with the wall.

4. BRACING

One wooden brace and two iron braces are to be put in, as shown upon the plan hereto annexed. The wooden brace is to be of one piece, or of two pieces well bolted together, of selected lumber, free from knots and other imperfections, squared, and measuring 6 by 8 inches in cross section. The iron braces are to be of 1 inch diameter, best quality wrought-iron rods. The bearing plates, four to each rod, are to be not less than 10 inches in diameter, of sufficient strength, and securely and permanently fastened to the braces.

5. WIRE FENCING

Such area as may be determined is to be fenced with the best quality of galvanized iron barbed wire, strung upon posts placed 20 feet apart. The posts are to be of mesquite, not less than 3 inches in diameter and of a reasonable degree of straightness (not varying more than 5 inches from a straight line). The posts are to be at least 6 feet 6 inches long and are to be planted perpendicularly with 4 feet 6 inches clear and at least 2 feet below the ground surface. Three lines of double wire are to be stretched upon and securely fastened to the posts, the first at a distance of 2 feet from the ground, the second at 3 feet, and the third at 4 feet from the ground. Two gateways are to be provided, at such points as may be directed, the side posts to be of squared timber, 6 by 6 inches in cross section, and the gates to be made of sawed lumber 1 inch by 5 inches, hung upon good iron hinges, and leaving a clear space of not less than 12 feet when open, the whole to be executed in the best and most workmanlike manner.

6. ROOF

The building is to be crowned by a roof of corrugated iron, supported in the manner shown in the accompanying plan and sections. The uprights are to be of selected squared lumber 1 foot square, each in a single piece, the lower ends planted at least 3 feet below the original ground level, and to be braced and tied to each other, as shown in the plan. The tie pieces are to be of selected squared lumber, 4 inches by 6 inches in cross section. The roof is to be framed and braced in the ordinary manner, and this framing is to extend beyond the outer wall 6 feet. The covering is to be a good quality of corrugated iron roofing, securely fastened to the framework, and painted with three good coats of the best quality of roof paint. The whole to be constructed and executed, in the best and most workmanlike manner, of good materials throughout, and to be of a strength sufficient to withstand the windstorms to which it may be subjected.
