For firms with developer clients

Planted in spring. Handed over on record.

A new building’s green roof and its post-construction stormwater structures need care before anyone owns them for good: watering, filling gaps, clearing outlets, and an inspection before responsibility passes. Manteverde is built for the firm that carries them through the first season and records the handover.

What developers judge you on

Four things a developer asks of the firm that cares for a new roof before handover.

  1. Young planting fails quietly

    Plugs dry out in the first summer and gaps open before anyone notices. The developer wants to know the roof is establishing, zone by zone, not to discover bare patches at handover.

    On the recordCoverage in each zone at every visit, drawn against the specification target.

  2. Handover has a date

    Responsibility passes to the owners on a day set in the sale. The roof and every new structure need to be inspected and documented before then, not after.

    On the recordA handover inspection per structure, signed by your inspector.

  3. New structures hide construction leftovers

    Sediment from the site, debris in the outlets and filter fabric left in place are common in brand-new structures, and they belong to the developer’s side of the line.

    On the recordFindings found before handover kept separate, with photos and dates.

  4. The next owner starts from your record

    Whoever takes on the maintenance agreement next, often your own firm, starts from the condition at handover. That baseline is worth more than any brochure.

    On the recordThe first season and the handover kept as the start of each structure’s history.

The first season

From planting day to the handover inspection.

Larkspur Yards’ green roof through its first season: coverage rises zone by zone across the establishment visits; one zone lags behind the line and gets infill planting. Then the handover inspection is signed and the owners’ agreement takes over.

What Manteverde is built to do

For the new buildings you take on.

  • Set up the new building’s roof zones and structures on its site map from day one
  • Plan the establishment visits on the Season Calendar: watering, infill, outlet clearing
  • Record coverage in each zone against the specification target you set
  • Run and sign the handover inspection for each structure
  • Carry the record straight into the owners’ maintenance agreement

Manteverde records what was inspected and done. It doesn’t warrant the roof, the membrane or the structures, or accept them on anyone’s behalf.

Where the work sits on a new building

Everything that was just built.

A new building arrives with a new set of structures. Each one starts its history on your record.

  1. The new green roof, zone by zone
  2. Drainage outlets and inspection chambers
  3. Bioretention planters at the entrance
  4. The permeable courtyard
  5. The underground detention tank
  6. The connection to the street

Inspections record what is observed on the day. Manteverde does not warranty or certify membrane integrity, structural condition or safe entry, and never files anything with a city or agency: reports are formatted for your client’s own submission.
