Mockups: After sample approval but before production fabrication of architectural precast concrete units, construct full sized mockups to verify selections made under sample Submittals and to demonstrate aesthetic effects and qualities of materials and execution. Mockup to be representative of the finished work in all respects including glass, aluminum framing, sealants and architectural precast concrete complete with all anchors, connections, flashings, and joint fillers as accepted on the final shop drawings. Build mockups to comply with the following requirements, using materials indicated for the completed work:
Revise or delete subparagraphs below to suit Project.
Build mockups in the location and of the size indicated or, if not indicated, as directed by Architect.
Notify Architect in advance of dates and times when mockups will be constructed.
Obtain Architect’s approval of mockups before starting fabrication.
In presence of Architect, damage part of an exposed face for each finish, color, and texture, and demonstrate materials and techniques proposed for repairs to match adjacent undamaged surfaces.
Maintain mockups during construction in an undisturbed condition as a standard for judging the completed Work.
Demolish and remove mockups when directed.
Retain subparagraph below if mockups are erected as part of building rather than separately and the intention is to make an exception to the default requirement in Division 1 Section, ”Quality Requirements” for demolishing and removing mockups.
Approved mockups may become part of the completed Work if undamaged at the time of Substantial Completion.
Delete paragraph below if mockup above is to be used for Testing Mockup.
Testing Mockup: Provide a single full sized mockup for testing by others to the extent shown or indicated to simulate the precast and window wall assembly. Refer to Division 8 WINDOW AND CURTAIN WALLS for requirements applicable to testing architectural precast concrete systems in conjunction with windows and window wall.
Delete below if Work of this Section is not extensive or complex enough to justify a pre-installation conference. If retaining, coordinate with Division 1.
Pre-installation Conference: Conduct conference at Project site to comply with requirements in Division 1 Section “Project Management and Coordination.”
PRODUCT DELIVERY, STORAGE AND HANDLING
Store units with adequate dunnage and bracing and protect units to prevent contact with soil, staining, and to prevent cracking, distortion, warping or other physical damage.
