Inspection: Before plaster is applied, surfaces to be plastered shall be carefully examined by the subcontractor. The Engineer shall be notified of unsatisfactory surfaces or conditions. Application of plaster shall not roceed until any imperfections, irregularities and unsatisfactory conditions that may y compromise the final finish shall be corrected and ready to receive work. Proceeding with the application will constitute acceptance of the substrate by the Contractor. Any corrective effort required to correct the substrate after application of the stucco will be at the Contractor Is sole expense.

If the method the Contractor has chosen to prepare the surface has not adequately removed all foreign material down to clean substrate, the Engineer can direct the Contractor, at no additional cost to the Owner, to use an alternative method to prepare the affected surfaces in accordance with the specifications. Handrail Repair: Embedded items in the concrete, sucl metallic material which have been de anchored by external measures are to location cleaned out in accordance w. damage to the railing post or the surr, to be filled and the railing posts are tc thickness of a high modulus, 2- coml epoxy bonding/grouting adhesive ma as railing posts, made of aluminum, steel or other ;rmined to be loose, deteriorated and/or previously >e removed by approved methods and the penetration h manufacturers specifications and without causing .inding concrete deck. The cleaned out penetrations are be embedded in a minimum of 1 " surrounding inent, solvent free, moisture insensitive, non -shrinking, trial as manufactured by Sonneborn or approved equal. 2. Embedded fasteners and accessories, I if required to further strengthen the stability of the handrails, are to be made of ASTM A316 stainless steel, especially where used to secure aluminum components to the concrete. All penetrations required to fasten the component to the concrete are to be sealed either by the application of a silicon sealant to the fastener or by bedding the component in an approved epoxy material to assure proper adhesion and against moisture penetration. The placement) of such fasteners shall in no way interfere with the drainage of the surrounding concrete surface. 3. If the affected handrail bases are deteriorated to a point where adequate structural reinforcement will not be provided by placement of external'accessories, inserts of similar material shall be used to reinforce the railing posts. The inserts shall be embedded into the concrete slab and inserted into the main railing posts and bolted for stability. The cut sheets of the proposed inserts shall be submitted and reviewed by the Engineer prior to final approval for placement. i 4.
