materials & maintenance

materials & maintenance

free – diluted latex paint, hand & HPLV-sprayer applied

fly – weathering steel (A588 plate) & cold-rolled steel (acorn squirrel shield, pipe)

flow -- 3M Control Tac/Avery 6060 Anti-Graffiti Laminate, Sintra PVC Board, CD files

flume – cut, honed & engraved igneous river rock, CD files

At this point, anticipated routine maintenance would consist of very little as it relates to our base project deliveries (tree-painting, metalwork, photos, stonework).  The tree paint (diluted latex) will gradually fade over 3-5 years.  Weathering steel will develop a protective oxide patina requiring little maintenance over a 30-40 year lifespan.  Cold-rolled pipe and spun steel of the material thicknesses specified (1/4” to 3/8”) will last approximately 20-25 years if left untreated in the elements.  The photos covered with a UV-resistant anti-graffiti film should last at least 8-10 years before fading.  The stonework is essentially a permanent material.  Conservatively call it a 50+ year lifespan. 

On the other hand, the wooden birdboxes and any additional landscaping elements will require some ongoing attention as part of a larger effort to create human presence and stewardship in Oak Tree Park.  Anticipate semi-annual cleanings of the birdboxes and replacement structures every 5-7 years.  Landscaping is an ongoing seasonal effort.   

As stated earlier, we will provide a complete maintenance manual with detailed instructions for care of all artworks upon completion and release of work.  We will also provide digital files for replacement images for flow, waterjet cutting for fly and fossil engravings for flume.
