1. Site list and access: How many separate sites are in scope, where are they (district / coordinates / road access), and what is the road condition to each site for a dump truck and a lowboy/excavator trailer? Any seasonal or weather access limits? Coordinates of sites/ number of sites are provided in scope of work. Majority of sites are located off paved roads/state highways. Recommend visiting sites or using google earth or map program to research access.
2. Pumping: Will the Government pump out the vaults before demolition, or is pumping/handling of vault contents the contractor's responsibility? If the contractor's, what disposal facility and manifesting are required for the contents? Vault pumping and disposal is contractors’ responsibility. See SOW excerpt below

“3.2 WASTE PUMP-OUT AND VAULT CLEANING

A. Pump the entire contents of the vault using a licensed and permitted septage hauler. Spray down vault interior to remove any remaining solids, slurry, washdown residue, or debris from vault interior and pump out prior to backfilling. B. Transport all pumped waste to an approved and permitted disposal or treatment facility in accordance with local regulations.”
3. Structures: What are the vault toilet buildings made of (precast concrete CXT-type, CMU/block, wood frame) and what are their approximate sizes/weights? Are drawings or photos of each structure available?
This information can be determined from the photos, Attachment C. Weights or drawings are not available.
4. Vault treatment: For decommissioned vaults, is the requirement to remove the vault tank, or to pump, crush/collapse, and backfill in place?

Please see 3.5 backfilling and compaction on page seven of SOW for information regarding backfill of these units. Backfill material will either need to be hauled in to Gomez Peak and

Little Walnut demolition sites or use excavated material from CXT toilet install to backfill old, demolished toilet area.
5. Disposal: Is there a designated landfill/disposal facility, or is the facility the contractor's choice? Any materials requiring special handling (treated wood, roofing, hazardous)?
