Investigative Probes for Village Hall and Library

The scope of work includes investigative probes to provide information on the condition of the parapets, masonry and concrete structures, and concrete reinforcement and to allow for the documentation of the existing structural framing of the Village Hall and Library roofs. Probe #1-4a: Parapet Wall and Roof Deck Intersection Remove a 2’-0” x 2’-0” area of the stucco coating on the vertical parapet surface and remove three courses of brick masonry within the probe area. Create a 2’-0” x 2’-0” opening in the horizontal roof membrane and deck and remove the copper base flashing at the vertical parapet surface. Scope: Requires removal of interior parapet stucco coating and base flashing to expose face masonry at parapet and further removal of three courses of brick masonry above the roof deck from the innermost wythe of the parapet wall. Also requires removal of roofing membrane, insulation, and wood deck to expose the roof framing members. Allow for Architect inspection of the bearing conditions and the interface of the masonry and decking, and documentation of the size, spacing, and condition of the wood framing. All probe locations are to be closed at the conclusion of investigation and made watertight. Replace removed decking and seal openings with liquid-applied membrane. Reinstall base flashing and patch stucco finish with new Sto stucco coating. Probe #4b: Parapet and Portico Roof Deck intersection Remove 2’-0” x 2’-0” area of roofing membrane and deck adjacent to scupper to expose portico roof framing. Remove three courses of brick masonry within the probe area. Area of removal to be directly opposite Probe #4a across the parapet. Note that opposite scupper from the one indicated in the probe plan can be selected for probe based on potential for secure access and required tie-off points at main roof. Scope: Requires removal of roofing membrane, insulation, and wood deck to expose the portico roof framing members. Remove three courses of brick masonry from the exterior wythe of the parapet wall adjacent to the scupper. Note that brick removal must not be done in tandem with masonry removal specified for Probe #4A. Allow for Architect inspection of the bearing conditions and the interface of the masonry and decking, and documentation of the size, spacing, and condition of the wood framing. All probe locations are to be closed at the conclusion of investigation and made watertight. Replace removed decking and seal openings with liquid-applied membrane. Replace areas of brick masonry removal with new brick units to match existing. Easton Architects to approve sample of proposed replacement brick during probe work prior to the closing of the probe area. Probe #5: Brick Mortar Sampling & Patching Remove six linear inches of brick mortar from main facade. Scope: Requires removal of six linear inches of brick mortar from location(s) indicated by Architect in the field. Repoint areas of mortar removal with new mortar to match the existing. Easton Architects to approve mortar finish color, prior to the completion of the repointing. Probe #6-7 & #10: Concrete Spandrel and Roof Deck Intersection Remove 2’-0” wide area of the stucco coating on the vertical spandrel surface and sound concrete face of spandrel beam. Create a 2’-0” x 2’-0” opening in the horizontal roof membrane above the probe below down to the deck. Scope: Requires removal of 2’-0” wide vertical band of exterior stucco coating along the full height of the spandrel beam and sounding of the underlying concrete beam. If directed by Architect or Engineer, remove a minimal depth of concrete (+/- 1.5” in depth) from face of beam. Remove roof membrane in a 2’-0” x 2’-0” area behind the gravel stop directly above the spandrel probe; requires removal of membrane, insulation, and flashing membranes to expose concrete deck below. At Probe #7, cut back the gravel stop to allow for inspection of the roof edge. Allow for Easton Architects to inspect the structural framing conditions and configurations. All probe locations are to be closed at the conclusion of investigation and made watertight. Apply a bituthene coating to any exposed steel, patch areas of removed concrete, and patch stucco finish with Sto stucco coating. At Probe #7, replace removed sheet metal gravel stop edge and flash into roof repair with liquid flashing membrane. Replace removed roof insulation and seal openings with a liquid-applied membrane. Probe #8-9: Concrete Spandrel Sounding Remove 2’-0” wide area of the stucco coating on the vertical spandrel surface and sound concrete face of spandrel beam. Scope: Requires removal of 2’-0” wide vertical band of exterior stucco coating along the full height of the spandrel beam and sounding of the underlying concrete beam. If directed by Architect or Engineer, remove a minimal depth of concrete (+/- 1.5” in depth) from face of beam. All probe locations are to be closed at the conclusion of investigation and made watertight. Apply a bituthene coating to any exposed steel, patch areas of removed concrete, and patch stucco finish with Sto stucco coating.
