Oregon A Progression of Construction By
Introduction
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
A more typical construction site!
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.
Preparations were made for utilities & for concrete footings…
Footings were protected from the elements
Footings formed Utilities
placed
Reusable Formwork was erected to pour the concrete mass wall…
Wood block-outs shaped the mass wall openings
Cranes were used to place the gang forms
Winter weather? It happened!
The sun came out again, and we got busy installing radiant floors and pouring slabs.
Slabs were water cured
PEX radiant floors fed by electric heat pump
units provide space conditioning without the use of fossil fuels
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.
Structural steel elements help support the larger elements of the building.
One great door frame being installed
Steel and wood develop the dynamic shape of the building inspired by the
Central Oregon Landscape.
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.
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
Back inside, HVAC duct and copper lines were being installed.
A TPO roof membrane was put on.
Exterior Tyvek, rigid insulation & furring clips were being installed around the
complete building perimeter. Inside, foam insulation was applied to the ceilings.
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) · Stockpiled topsoil (LA-02)
Great Doors
Commissioning
Process validates that all MEP systems are operating efficiently as designed.
Process is a 3rd party inspection of installed MEP systems
