86 Unitarian Universalist Fellowship of Central Oregon A Progression of Construction By Introduction

87 Plan ahead for optimal results Excavation bid documents defined expected care for the site. Forward thinking and planning in advance is the key to exceptional results

88 A more typical construction site!

89 Protection of the natural site All trees near construction activity were protected Trees that were removed were salvaged for reuse. Prior to excavation road edges are protected.

90 Preparations were made for utilities & for concrete footings Footings were protected from the elements Footings formed Utilities placed

91 Reusable Formwork was erected to pour the concrete mass wall Cranes were used to place the gang forms Wood block-outs shaped the mass wall openings

92 Winter weather? It happened!

93 The sun came out again, and we got busy installing radiant floors and pouring slabs. PEX radiant floors fed by electric heat pump units provide space conditioning without the use of fossil fuels Slabs were water cured

94 Going vertical with wood framing was the next step Natural Areas are still roped of to keep the impact of large work crews, equipment and vehicle parking minimized.

95 Structural steel elements help support the larger elements of the building. One great door frame being installed

96 Steel and wood develop the dynamic shape of the building inspired by the Central Oregon Landscape.

97 Masonry walls were built within the natural landscape that represent uplifted native rock. Not anything specified but masons traditionally use excess material to fill non visible area of their work. Fenced off areas still protecting the natural beauty of the site.

100 Quality Control Under-slab insulation and vapor barrier Weather resistive barriers Thermal insulation at building walls Rain screen installation Roofing and insulation Mechanical Electrical and Plumbing Quality Control Mechanical pipe hanging methods Pipe insulation Duct insulation Leak testing Equipment selection, submittals and field validation Duct routing choices utilizing SMACNA standards Jurisdictional inspection coordination

101 Back inside, HVAC duct and copper lines were being installed.

102 A TPO roof membrane was put on.

103 Exterior Tyvek, rigid insulation & furring clips were being installed around the complete building perimeter. Inside, foam insulation was applied to the ceilings.

104 Earth Advantage Field Verification -GC Role: Via the submittal process we Track: Recycled materials (MA-01/04/07) Locally sourced materials (MA-01/04/07) Reduced Urea Formaldehyde Wood Products (HE-06) Utilize sustainable timber (MA-12-14) Utilize only Low-Emitting Interior Paints & Coatings/Adhesive, Sealants, carpets & Pads/Insulation (HE-02, HE-04) Made sure all materials matched specifications or that alternates maintained compliance with EA requirements Via Closeout Process we: Provide Owner Training (EN-07) Provide Owner Documentation (EN-07) Construction Certification and Acceptance Testing (EN-04/11) Via Daily Log and Site Walks we: Uphold Storm Water Pollution Prevention (WA-05) Indoor Air Quality best practices (HE-01) Recycling of building materials including wood, metal, cardboard & plastics (MA-03/05/08)

105 Great Doors

106 Commissioning Process validates that all MEP systems are operating efficiently as designed. Process is a 3 rd party inspection of installed MEP systems
