Questions for Winters-Schram

1. Green roof contractor/ design/ warranty issues: Due to time, schedule, concerns we propose that winters-schram contract with one of the following thus increasing their ability to get best pricing, warranty and have most barganing power to get best product, best warranty and fastest installation. The following recommendations will provide specifications based on existing site conditions( ie steep roof slopes and proposed designs of grading and plants.)

1. Roofscapes: Charlie Miller: He will provided Design, Supply optigreen parts, and bid out to certified contractors. They will provide warranty for everything above the membrane.

2. Conservation Technology: Lee Glaslow: They provide design and supply parts and specifications, which Winters-Schram can then bid.

3. Hydrotech: waterproofing and all of the above. They will offer total warranty for whole system. There is a chance that Hydrotech will provide and specs and warranty above the membrane.

Evo will provide contact, recommendations, general guidance as well as due diligence.

2. Irrigation Contractor: Again due to schedule we propose that winters-schram contract directly with an irrigation designer/ contractor so as to get best pricing as many products come with designer/ warranty etc...the connections to roof also need to be in place ASAP. Initial Questions focus on segue btw architecture and landscape. Tap locations and sizes, water pressure in G.P.M. and electrical needs to runs system. Are there sleeves in the parapet walls to accommodate irrigation

Evo will need to work directly with irrigation contactor/designer to accommodate proposed design especially with regards to slopes, growing media and plant establishment, LEED requirements, and client audience expectations.

Below are a few options:

1. KissUSA they have designers in CA and it is irrigation specifically for green roofs. Their system may be beneficial for sloped areas.

2. Local irrigation designers: Habitat Gardens, other Winters- Schrams contacts

3. Does anyone with Belzberg, Winters- Schram or LAMOTH have connections with NETAFIM for possible donations?

3. Site Visits: Can we schedule these ahead of time so we can be present when needed. Are there other things going on with the building ( like back fill ) in the next few weeks that require decisions/recommendations on our part? How does building schedule interface with Landscape design and install?

1. reorganize construction admin with contract for cost based on number of site visits to clarify contract.

2. Collaborative scheduling for time and cost savings
