Whole Building Design Guide Federal Green Construction Guide for Specifiers This is a guidance document with sample specification language intended to be inserted into project specifications on this subject as appropriate to the agency s environmental goals Certain provisions where indicated are required for U S federal agency projects Sample specification language is numbered to clearly distinguish it from advisory or discussion material Each sample is preceded by identification of the typical location in a specification section where TM it would appear using the SectionFormat of the Construction Specifications Institute SECTION 02360 SOIL TREATMENT SPECIFIER NOTE resource management For soil treatment options resource management issues closely parallel toxicity issues The more environmentally friendly alternative to canvassing the construction site with poison is to investigate evaluate and adjust the local ecosystem such that the undesirable creatures are not attracted to materials and areas in which they are unwanted For example tree limbs or vegetation that touch the exterior walls or roof provide excellent transportation for unwanted wood boring insects Rather than spraying the yard consider relocating and or trimming plants toxicity IEQ This section typically specifies pesticides and herbicides to control unwanted vegetation rodents and insects Soil treatments directly impact soil and groundwater they directly impact the hydrologic cycle and the food chain Therefore utilize the least toxic treatment possible Alternative control methods include low tech options such as soil solarization refer to Section 02900 Landscaping performance Termite infestation exists throughout the United States and overseas areas with the exception of Alaska Some construction systems such as masonry steel and concrete are not considered to be susceptible to termite damage Alternative termite prevention systems such as a termite sand barrier generally require preventative maintenance on the part of the building owner such as keeping vegetation and dead leaves away from the building Verify that the owner understands the maintenance involved and is willing to perform such maintenance Alternative systems may be used in combinations For example a mesh barrier system may be used in combination with other preventive measures such as a sand barrier system and pressure treated lumber for construction Alternative systems may require a variance PART 1 GENERAL 1 1 SUMMARY A 1 2 Section includes 1 Sand barrier termite control 2 Mesh termite control SUBMITTALS A Product data Unless otherwise indicated submit the following for each type of product provided under work of this Section SPECIFIER NOTE Green building rating systems often include credit for materials of recycled content USGBC LEED v2 2 for example includes credit for materials with recycled content calculated on the basis of preconsumer and post consumer percentage content and it includes credit for use of salvaged recovered materials Green Globes US also provides points for reused building materials and components and for building materials with recycled content http fedgreenspecs wbdg org 11 02 05 02360 1 Soil Treatment Whole Building Design Guide Federal Green Construction Guide for Specifiers 1 Recycled Content a Indicate recycled content indicate percentage of pre consumer and postconsumer recycled content per unit of product b Indicate relative dollar value of recycled content product to total dollar value of product included in project c If recycled content product is part of an assembly indicate the percentage of recycled content product in the assembly by weight d If recycled content product is part of an assembly indicate relative dollar value of recycled content product to total dollar value of assembly SPECIFIER NOTE Specifying local materials may help minimize transportation impacts however it may not have a significant impact on reducing the overall embodied energy of a building material because of efficiencies of scale in some modes of transportation Green building rating systems frequently include credit for local materials Transportation impacts include fossil fuel consumption air pollution and labor USGBC LEED v2 2 for example includes credits for materials extracted harvested and manufactured within a 500 mile radius from the project site Green Globes US also provides points for materials that are locally manufactured 2 Local Regional Materials a Sourcing location s Indicate location of extraction harvesting and recovery indicate distance between extraction harvesting and recovery and the project site b Manufacturing location s Indicate location of manufacturing facility indicate distance between manufacturing facility and the project site c Product Value Indicate dollar value of product containing local regional materials include materials cost only d Product Component s Value Where product components are sourced or manufactured in separate locations provide location information for each component Indicate the percentage by weight of each component per unit of product 1 3 WARRANTY A Mesh System Warranty Provide a 3 5 xxxx year written warranty against infestations and reinfestations by subterranean termites of the building s and building additions constructed under this contract 1 Perform annual inspections of the building s and building additions If live subterranean termite infestation or subterranean termite damage is discovered during the warranty period and building conditions have not been altered in the interim the Contractor shall a Correct defective mesh installation and perform other treatment as may be necessary for elimination of subterranean termite infestation b Repair damage caused by termite infestation and c Reinspect the building approximately 180 calendar days after the repair PART 2 PRODUCTS 2 1 SAND BARRIER TERMITE CONTROL SPECIFIER NOTE Because termites live in moist underground colonies and travel upwards into buildings only to feed on the wood they build shelter tubes above ground where they would be exposed to the outside air which would dry them out and kill them Termites are very capable of digging through soil But they are unable to dig through sand of certain grain size Grains of approximately 1 6 to 2 5 mm particle
