Client comments: We meant that if the dumpster were inside a bay, then we would like to have the roll-up door. I think the concept there was the wall would be up against the slope adjacent to the existing elevated access road, and the door would be there so you could pull up alongside, open the roll-up door, and pitch stuff directly down into the dumpster. The Site Plan will need paved access ways added. A pavement cross-section will be needed as well. As they develop their drawings further, more detail on how the dumpster interfaces with the adjoining slope would be helpful. Maybe add the surrounding grade profile to an elevation drawing. I think we hope that the dumpster could sit just below the existing elevated access road, so we can roll up alongside and pitch material into the dumpster without having to toss it up and over the dumpster sidewall (similar to a typical solid waste transfer station/dump). Another consideration is that I thought there needs to be some type of containment in the bay that holds the catch basin debris. It will get relatively wet and run all over. some kind of lip or recessed bay holds the watery debris until it drains. Site Description: 1. EXISTING SITE CONDITIONS The existing site for the proposed structure is an uneven lot partially covered in gravel. The impact of trucks can be seen when dumping a variety of street debris along with sand and gravel left over from a variety of projects and cleanup efforts (Figure 1.2). The site is large enough that many different configurations can be considered for the placement of the structure. The existing neighboring structure has bays on the side of the building facing the area where the shelter would be built, access to these needs to be maintained. The rest of the surrounding area is an open field with few trees, leaving the area exposed to the wind. • • Figure 1.2: Site currently used for unsorted debris. The third design choice which was considered stemmed from a metal roof support design. Having rigid metal supports and panels instead of canvas material would be more suited for high wind load areas. design involves placing the dumpster in a selected bay. This option will complicate the design of the dump area as the suggested dumpster would need to be placed at a level surface and will need an extraction method. This consideration will complicate the construction process and will add complexity to the design. The bay dumpster location will however make the design of the building itself simpler as no modifications or additions will be needed as compared to the side dump option. 3.1 SITE LOCATION The determination of structure footprint was estimated using required storage of debris decided by the client and 20-yard dumpster dimensions of 7ft wide x 22ft long (WM, n.d.). Height requirements to allow clearance for vacuum truck dumping were calculated using truck specifications for a Supersucker truck similar to the Vac-con truck currently used by the client (Super Products, 2023). Initial placement and orientation of the structure has the open bay side facing south as seen in the drawings in Appendix A. Due to potentially high uplift from wind, the structure will likely be rotated so that the open bays are facing west which will get the least amount of uplift force. 3.2 BAYS The client requires one bay to contain 200-250 cubic yards of catch basin debris, four additional bays to hold 40 cubic yards of raw materials, plus a dumpster bay. The walls of the bay should be free to move if, in the future, the client's needs are different. This can be accomplished by building the bay walls out of a modular building block such as Megablocs that can be rearranged with a forklift. While the client does not require that the bays for 3/4- gravel be covered, they would prefer the maximum amount of covered space, and with the request for a modular design, it makes the most sense to cover all the space dedicated to bays. 3.3 ROOF The roof will be made of metal and cover all of the bays. As the interior walls of the bays will be designed to be moveable, the roof will be fixed to the exterior walls only. 3.4 DUMPSTER BAY DOOR The client has inquired about a roll-up bay door for the dumpster area. This will be the only bay opening that has a door on it. The dimensions of the opening may need to be adjusted to accommodate for truck clearance and to fit an off-the-shelf door. 3.5 DRAINAGE The discharge from the staging area into the sewer system may contain significant amounts of fine sediments that need to be removed before the runoff enters the main sewer line. A weir will be constructed that filters these sediments, which can then be cleaned by hand. 8:33 Tue, Apr 2 MA < Structure notes 30' -36 + 1 Plan View HSS Columns '- 15' + IS' + 15') ✓ G = n 92% W-beams -+-15' + # 30'- 30' C-perlins S Spacing SIDE ELEVATION T 24 C-girders 10 spacing, 15 Spans blu columns Front side elevation Soffit 2' I 22' HSS lower Soffit Connection ·30'- W-beams 30' 120' x 30' building 2/3
