This does not apply to debris and rubble of all types, from which excavation material shall be rid of;

these shall be disposed of at a dump, as prescribed at paragraph 1a-02. In case excavation is performed in presence of water and water level is below 20 cm height, the contractor shall remove water at his expense using the means he deems suitable. If water reaches higher levels, removal shall still be at contractor's expense only if the possible presence of groundwater is indicated on the drawings or in these specifications, and only to the extent indicated. In addition, the contractor shall prevent the access of water deriving from outside to the excavation site: in case water accumulates in excavated area, removal will be at contractor's expense. Struts and shoring shall be placed as necessary for the protection of the work and for the safety of personnel. Adequate precautions shall be taken for the protection of existing underground pipelines or electrical cables. Before any excavation is started, plans showing the approximate location of underground utility lines shall be furnished to the Contractor, upon his request. The area of excavation shall be delimited by trestles, gangplanks, and warning signs visible during night and day, to prevent injuries to persons, as prescribed by the ISPESL standards.

c. Excavation for Foundation and Appurtenances.

Excavation for manholes and similar structures shall be of sufficient dimensions as to leave a 12 inches (30 cm.) free space between their outer surfaces and the embankment or timber which may be used to hold the banks.

3b-02 BACKFILLING.

Trenches shall not be backfilled until foundation, pipes or cables have been inspected and approved.

Where, in the opinion of the COR, damage is likely to result from withdrawing of shoring, the latter shall be left in place. Trenches shall be backfilled with the excavated materials, if deemed suitable, free from large clods of earth, stones, and roots. Backfilling material shall be deposited in 15 cm.

(6") layers, thoroughly rammed until the trench is completely covered, and watered as necessary. Any material rejected by COR shall be replaced with material acceptable to the COR, coming from borrow pits located outside the US military base.

3b-03 REPAIRS.

All crossings of existing paved or asphalt coated surfaces shall be cut neatly vertical and horizontal.

At the completion of the work, pavement and sidewalks shall be restored to the original conditions.

Damaged lawns shall be sown again and damaged plants shall be replaced with others of the same kinds. Any damage caused during the work progress shall be repaired by and at the expense of the Contractor. The Contractor shall be responsible also for injuries caused to persons as a result of non-compliance with prescribed ISPESL norms.

3b-04 ADDITIONAL REQUIREMENTS.

In addition to above requirements, before starting the excavation, the Contractor must investigate with a metal detector furnished by himself the location of existing underground utility lines, e.g.

electrical, communications, water, TV lines, or any other utility which may not be shown on the existing condition drawings, in order to prevent damaging or interrupting any existing utility.

Investigation shall be done in the presence of the COR. Trial runs shall be done with the metal detector in the presence of the COR or his representative prior to the investigation. Investigation shall be done following COR approval of metal detector. The Contractor shall mark-up on a copy of the existing conditions the exact field location of the existing utility lines which are found during excavation.

SECTION VIIIa - REPAIR OF THE ROOF MEMBRANE

8a-01 REPAIR AND PREPARATION OF THE EXISTING MEMBRANES.

If the existing membrane is adhering well to the support, it shall be cleaned and dusted accurately and any grown up vegetation shall be removed. Afterwards a coat of bituminous primer in a solvent base, ready for use, shall be applied at the rate of about 200 g/sq m. The detached areas shall be glued by a propane gas torch. In case of crevices, first the treatment with the primer shall be applied, and subsequently a waterproofing membrane of elasto-plastomeric material reinforced with non-woven polyester fabric (4 mm thick) shall be applied. The strip of membrane shall be glued only along all the perimeter and shall extend on each side by 15 cm minimum over the area with the crevice. Any bobble shall be cut cross-wisely; after the contained humidity has gone, the cut edges shall be glued by a propane gas torch; a patch of membrane shall be applied to adhere totally to the restored area. The patch shall extend over the cut area by 15 cm as a minimum, along the total perimeter. In the connection areas, in the corners, and where there are strain and fissures, adequate reinforcing stripes of membrane shall be glued after smoothing the edges with adequate profiles. Where the concrete supports have been removed, an insulation similar to the existing one and having the same thickness shall be installed after coating the support with a bituminous primer and closing the bitumious membrane by gluing it with a propane gas torch.

8a-02 WATERPROOFING.

The waterproofing shall consist of a new membrane to be applied after the surface has been repaired (as required at the preceding paragraph). An accurate cleaning of the existing membrane with methods deemed as most suitable by the contractor shall be performed; the selected methods shall, however, ensure a surface preparation adequate to receive the primer application. The primers to be used for the priming shall be of two different types: one for cement containing supports to be used on the existing bituminous membranes, and the other for non-porous supports such as metallic surfaces of the flashings. The primer quantity shall be 150/200 gr/sq m. At the completion of all preliminary operations, the plasto-elastomeric membrane reinforced with uninterrupted polyester thread, 4 mm thick, protected with gray color slate chips shall be applied for a total adherence, using a propone gas torch. The connections between sheets shall be obtained by overlapping adjacent edges: 8-10 cm at the sides and 12-15 cm transversally.
