Waste material shall not be thrown down, but rather, it shall be conveyed or guided downward, after wetting it to prevent raising dust.

During demolition or removal work, the Contractor shall adopt every measure suitable to avoid deterioration of the items which may be reinstalled, or which, in the opinion of the COR, may be used at a later date. These items shall be cleaned, guarded, hauled and set neatly in the storage areas indicated by the COR.

When repaired, the wall surfaces shall be made perfectly smooth by sandpapering and subsequently primed. All paints, enamels, special products, etc., shall be delivered to the site in original unbroken containers with intact labels and tags and used either pure or with the thinners indicated by the manufacturer.

Color selection is a prerogative of the COR, who will become the owner of the specimen submitted by the Contractor. The paint coats applied over the primer shall be of different shades so that at any time it may be possible to check the number of applied coats. Prior to starting the paint work, samples of the various finish work shall be prepared at the locations indicated and with methods specified. These samples are necessary for selection of colors and workmanship. If necessary, samples shall be prepared a second time with the modifications requested, until approval of the COR is obtained. All precautions and methods suitable to avoid paint splashes or stains on the finished surfaces will be adopted by the Contractor. All damages caused by the Contractor shall be repaired at no cost to the US Government.

7d-02 MATERIAL. The following materials shall be used:

a. Interior Masonry Surface.

- Primer, copolymer base in water emulsion.

- Water paint for interior surfaces, resin base.

b. Exterior Masonry Surfaces.

f. All new and replaced exterior doors shall be provided with marble thresholds.

g. All new or replaced windows shall be equipped with new marble sills. Marble shall be type TRANI. The new sills shall project from the masonry by 3 cm., both inside and outside the building. All marble sills will be of the same color and quality as approved by the COR. The sills shall consist of 3 cm. thick whole slabs and shall be complete with exterior rain drip and with a marble seal strip 2 cm. high and 1 cm. wide.

h. All new or modified openings shall be provided with lintels.

i. A master-key that will open all locks installed on the doors of each building shall be furnished in triplicate.

j. A floor mounted door stopper shall be installed at each interior door to prevent sash from hitting against the wall.

k. Jambs shall be perfectly plumb. Existing jambs shall be rectified if necessary.

l. If necessary, skirting boards must be fitted to a measure or restored if damaged.

9a-02 ADDITIONAL NORMS FOR REPLACEMENT OF EXISTING DOORS AND

WINDOWS.

a. The door and window opening dimensions indicated on the drawing are indicative and are given only to enable the Contractor to make an approximate evaluation of the surfaces. Before preparing the doors and windows, the effective dimensions shall be verified on the field. Doors and windows shall fit the true dimensions of openings, except when an opening modification is requested.

b. Replacement of window sills calls for removal and reinstallation of all radiators and reflecting panels located under the windows.

c. The existing security bars and apparatus removed during windows replacement shall be reinstalled. The Contractor must work out a system to replace the windows without removing the iron grates or prepare temporary sheet iron shields to be installed during non working hours at no cost to the US Government. In any case such shields will offer the same security against breaking in from the outside as the grates removed.

d. The presence of staff angles of any material whatsoever will not add to the expense for the US Government.

9a-03 SUBMISSIONS.

a. Before the installation of any type of door or window, the following documentation shall be submitted for COR's approval:

(1) Shop drawings including layouts, sections on scale of 1:1, details on fixing, connections, installation methods, and accessories.

(2) Certificates of compliance as required at paragraph 9a-05.

b. After shop drawings have been approved by the COR, the contractor shall construct a sample on scale of 1:1 for each type of window or door he has to install. Samples shall be submitted to COR's approval; after this approval has been obtained, samples will be used in contract work.

9a-04 MATERIALS. Doors and windows shall be constructed of anodized aluminum tubular open type stiles and rails, natural color. Stiles and rails shall be extruded primary alloy UNI 3569- 66, hardened and tempered to TaA. Anodic oxidation shall conform to code UNI 4522-66.

Complementary weatherstripping for slide sashes shall consist of strips made of high density water-repellant synthetic wool with central polypropylene flexible fin. The fin shall be one single body with the wool support. Parts subject to wear and tear shall be assembled and locked by contrast for easy adjustment or replacement also by unskilled personnel without any mechanical work. The glass pane shapes shall be snap-on type. Care shall be taken in avoiding that snap-on fastening is obtained through elasticity of the metal. Fastening shall afford maximum safety so that in case of wind pressure, the glass pane shape will not yield elastically. Glass panes or "vetrocamera" panes shall be installed in strict compliance with code UNI 6534-74.

9a-06 INSTALLATION. All doors and windows shall be provided with steel tubular buck of the dimensions indicated on the drawing that shall extend over the three sides that do not rest on the floor or on the sill. The buck shall receive two coats of a rust-inhibitive paint approved by the COR. Except for type C door, the vertical sides of the buck shall be provided with 180x30x6 flat iron anchors, horizontally slanted toward the center of the jamb. The top of the buck shall be anchored to the lintel by three M8 bolts, screwed to expansion shields for reinforced concrete. The buck shall be bonded by cement mortar and anti-shrinkage additive at the rate recommended by the manufacturer. If it is not possible to anchor the top of the window buck with bolts screwed to expansion blocks, as indicated on the drawings, it will be necessary to weld iron brackets (no less than 2) to the top of the buck. Brackets shall be equally spaced one every meter and will be welded to the reinforcement of the lintels or into the flange of the metal lintels. The forward masonry must be built by means of a hollow flat block or of a lath in accordance with the COR's prescriptions. Opening existing above doors shall be blocked with brick masonry supported by a new concrete lintel. Existing jambs shall be altered to fit the new door dimensions. Jambs shape shall not be chanted. The surfaces covered by this work shall be smooth plastered with fine sand and painted with one coat fixative paint and two coats paint to match the existing surfaces. If, after removing the existing door or window frame, chipping away the plaster or forward masonry, and building seats for the anchoring brackets of the frame, it turns out that the existing masonry is not made of bricks, multiholes or double UNI bricks, or if it is necessary to build a forward masonry or plastering of over 3 cm to adjust the opening to the dimensions prescribed by general specifications, the Contractor will have to tear down the reveal and reconstruct it of concrete.

Jamb width must be the same of the wall; depth must be no less than 15 cm. The installation of the buck must take place at the same time of the concrete casting. The frame shall be fastened to the buck by spacers and 6 mm diameter stainless steel screws AISI 316, complete with stainless steel washers and tightened to a bolt welded to the interior side of the buck.
