The control box is mounted nearby on the wall of the house. Photo attached is of the top of the tall pit at grade. 3 - structurally, I believe this is what you are looking for.. in the last pages of the attached, we noted the location to the structural engineer and he replied with a beefed up footer condition since the location required underdigging the foundation a bit. This particular page was not stamped .. if it's the right detail and you do need it stamped, I can have that done?? Or is there some other structural detail you are asking about?

Can you please provide additional answers to address the following code concerns: 1. Confirm that the sump only receives drainage from the lower level. The upper and main level should discharge by gravity to the sewer main. (International Plumbing Code 712.1) 2. Confirm that the access pit and valves are accessible (IPC 712.2) 3. Provide a stamped plan or letter from the structural engineer to demonstrate that the structure is adequate to accommodate the pump at that location. Once these are received, I stamp them as reviewed and issue you a copy back to the field for your records. Let me know if you have any questions.

Since this was neglected on our plan set, I coordinated here and thus currently have no official planset notating this thing. Below is the email I sent to the architect outlining the plan. What better way can I offer to get you this information? Just as FYI, this was installed and buried last fall. Thanks + Kevin Heinecken + 970-379-4238 kevin@madiganco.co + M From: Kevin Heinecken <kevin@madiganco.co> Sent: Wednesday,August 1, 2018 2:07 PM To: chris@madiganco.co Subject: Sewage Vault Submittal 2 Here is my best text for submittal. Hi Joseph—As we discussed,this project neglected to specify a sewer pumping vault. We have a suggestion figured out and would like to set it as below at about Grid B.5—1.75. Attached are the specifications for the duplex pumps and control panel.The shop drawing for the vault will not be released until we order it. It is a 36" diameter fiberglass tube of a pre-planned fixed height with a system to cut in inflow and outflow as decided on site. At a minimum,we would like it to be 18'tall. This height would allow at the best case 85 gallons of storage (important in the case of power failure).. at the worst case (pumps were just about to start) there would only be about 40 gallons of storage before sewer backup. We can design the vault much deeper but the issue becomes excavating for it which would impact the bearing of the footer above on native soil. We tried to pick an area where there are no beam loads above and my expectation is that concrete wall could span this as a grade beam although the hole will of course be backfilled to provide some bearing. The overdig of course won't be fully 4.5' deep at the outer circle but will laybak and be backfilled at least to that line. If you did need more or wider footer here,we can probably accommodate but would prefer to keep the bottom of the footer as currently shown, without any vertical steps due to waterproofing membrane. This general sketch below is what it will take to install an 18' tank. There is a trade off on specification—the deeper tank will dig more out of the footer bearing while providing more storage capacity. Less storage capacity will require less digging under the footer. The larger tank will of course cost more in materials and excavation. Please provide some guidance on the appropriate specification. We don't have much time to lose as this tank has to be set before footers can be formed and there is a lead time associated which requires ordering it this week. a • 2-9I/2'LVLW/HUC410W/ 14-1/4'0 x 13/4'SIMPSON TITEN SCREWS CI EA.END Edge of pathway ;` I above.
