National Monument Maintenance Building: 324 Issues Including Critical Life Safety & Structural Violations

Fixture EW2EM is designated as an emergency exterior fixture intended for path of travel illumination. It is specified as having an "INTEGRAL OCCUPANCY SENSOR." According to the Lighting Sequence of Operation, sequence iO1 (which corresponds to fixtures with an integral occupancy sensor) is programmed for "AUTOMATIC OFF" after a 15-minute timeout. This directly contradicts IBC Section 1008.2, which requires means of egress illumination to be provided at all times the space is occupied, and Section 1008.3.2, which requires emergency systems to automatically illuminate exterior landings upon power failure.

Lighting Fixture Specific Note 3 explicitly permits the contractor to purchase 'a used fixture from an online retailer such as eBay' for fixture type EW1EM. This fixture is designated as a historically compatible unit connected to an emergency inverter for means of egress illumination. IBC Section 2702.1.3 requires emergency systems to be installed in accordance with NFPA 70, which mandates that electrical equipment be listed and approved. A used fixture from an unvetted source cannot be verified to meet listing requirements (such as UL) or the 90-minute emergency duration required by IBC Section 1008.3.4.

The 'PLAN VIEW' of the collector plate on drawing I-S401 contains multiple geometric impossibilities. First, the specified transverse fastener pattern width totals 7.5 inches (3/4" + 6" + 3/4"), which is impossible to fit on the specified 7-inch wide plate ('COLLECTOR PL 1/4x7'). Additionally, the 1.5-inch transverse fastener spacing contradicts the requirement that fasteners be centered on the '2x' decking members ('CL BOLTS = CL 2x, TYP'). Per IBC 2304.2 and 2301.2, nominal 2x3 lumber (specified in Detail 09) has an actual width of 2.5 inches. A 1.5-inch bolt spacing across the boards would cause fasteners to miss the center of the structural members, violating the specified design intent and basic principles of structural sizing in IBC Chapter 23.

Drawing 0-S001, Foundation Design Note 1, explicitly states that the geotechnical report used for design (Report No. 17115.000) was 'prepared for the neighboring site and not intended for this project' and should be used for 'general reference only.' It further states that design recommendations are 'guidelines' that may be 'further modified by the special inspector's judgment during construction.' This violates IBC 1803.6, which requires a project-specific geotechnical report to be submitted at the time of permit application. Furthermore, IBC 1803.1 requires that geotechnical investigations and engineering calculations (design basis) be conducted by a registered design professional, not a special inspector during construction.

The 'RECIRCULATION PUMP SCHEDULE' specifies RCP-1 with a performance duty of 10 GPM at 17 FT of head, using a Bell & Gossett PL-30B as the Basis of Design. However, the manufacturer's performance curve for the PL-30B indicates a maximum shut-off head of approximately 17-18 FT. At the scheduled head of 17 FT, the pump's flow rate will be near zero GPM, making it physically incapable of delivering the required 10 GPM flow.

Section 2 showing the shed addition exterior wall (W2) and foundation assembly depicts the slab edge with insufficient embedment into the ground. The exterior grade line is shown meeting the wall above the bottom of the slab, but the graphical proportions of the slab (which matches the thickness of the 6-inch stud wall) indicate a total embedment depth of only a few inches. IBC Section 1809.4 requires that the minimum depth of footings below the undisturbed ground surface shall be 12 inches.

Detail 4 shows "SPRAY FOAM INSULATION" applied at the roof deck and top of wall, exposed to the interior space (no thermal barrier shown). The Code Summary states the Snow Equipment Building is "NON-SPRINKLERED". Per IBC 2603.4 (under the applicable code), foam plastic insulation must be separated from the interior by a thermal barrier (e.g., 1/2" gypsum board) unless specific testing allows otherwise. Leaving standard spray foam exposed in a non-sprinklered building is a code violation.

The specification explicitly defines Option 06 as the construction of Bay 03 "TO THE EAST" of the new Snow Equipment Building. However, the drawing elevations indicate "OPTION 06" is located on the West side of the building (labeled at Grid 16-17, which is the left side of the South Elevation and right side of the North Elevation, opposite the "BASE SCOPE" at Grid 14-16).

Keynote 26.02 requires the SCADA panel in Office 103 to remain operational and accessible to staff at all times during construction. However, the demolition plan shows the entire floor slab in Office 103 and the adjacent RR 102 (the only access path) is to be demolished, as indicated by the diagonal hatch. This directly contradicts IBC 3310.2 and 3302.1, which mandate that means of egress and required accessible means of egress be maintained during construction and alterations.

Detail 1 specifies a "24"W X 13"L X 12"H CONCRETE METER BOX" for a 2" water meter assembly. A standard 2" water meter body alone (AWWA C700) typically has a lay length of 17 inches, and the complete assembly with setter/valves requires significantly more space (often a vault or 30"x48" box). The specified 13" length is physically too small to contain the 2" assembly.

The Code Summary specification explicitly states that the new Snow Equipment Building is to be non-sprinklered. However, the Utility Plan depicts a 'FIRE RISER ROOM' within this building and notes instructions to route a fire riser drain and connect a 4" water line to the fire service, indicating a sprinkler system is included.

The drawing General Note 4 and details indicate that a shower is to be provided in the new accessible restroom. However, the Project Specification (Code Summary) Project Description and Plumbing Fixtures analysis only list a "new restroom and kitchenette" and do not include a shower in the scope or fixture calculations. This is a direct contradiction in the project scope defined by the specification versus the drawing.
