GR01A: Samples
are analyzed for particle size distribution (< 0.002 to > 12.5 mm) with
graphical display of results relative to FLL limits, dry weight density, density
at maximum water-holding capacity, total porosity, air-filled porosity at
maximum water-holding capacity, water
permeability factor (hydraulic conductivity), pH, total soluble salts, organic
matter, phosphorus, potassium, calcium, magnesium, nitrate and ammonium.
Methods followed are those specified in the FLL Guideline for the
Planning, Execution and Upkeep of Green-Roof Sites or equivalent ASTM methods
(ASTM E2399) with the exception of total porosity which is determined using a measured, not estimated, particle density. This test package meets the FLL
requirement for intensive and extensive multi-course and multi-layer
systems.
....................................................................................................................$260.00
GR01B: Test
GR01B is the same as Test GR01A but provides results for pH, total soluble
salts, phosphorus, potassium, calcium, magnesium, nitrate-nitrogen and
ammonium-nitrogen using the saturated media test procedure instead of FLL test
methods.
Saturated media test results for boron, copper, iron, manganese, sodium,
and zinc are also provided.
..... .............................................................................$235.00
GR02: Test
GR02 is the same as Test GR01 but without the plant nutrients phosphorus,
potassium, calcium, magnesium, nitrate and ammonium.
It may be used alone or in combination with alternative tests to those
recommended by FLL for plant nutrients (see Optional Tests below). Methods followed are those specified in the FLL
Guideline for the Planning, Execution and Upkeep of Green Roof Sites
or equivalent ASTM methods (ASTM E2399) with the exception of total porosity which is determined using a measured, not estimated, particle density. This
test package meets the FLL requirement for single
layer extensive system..................................................$210.00
GR03: Samples
are analyzed for the percentage of silt-sized (< 0.05 mm) particles; dry
weight density, density at maximum water-holding capacity, total porosity, water
permeability factor (hydraulic conductivity), pH, total soluble salts, and
organic matter. Methods followed are those specified in the FLL Guideline
for the Planning, Execution and Upkeep of Green Roof Sites
or equivalent ASTM methods (ASTM E2399) with the exception of total porosity which is determined using a measured, not estimated, particle density. This
test package meets the FLL requirement for drainage courses
for extensive multi-course
systems.......................................................................................................$175.00
Sample
size required for tests GR01A, GR02A, GR02 or Gr03:
approximately 5 gallons (20 L)
