Summary: The Architectural floor plan designates the area bounded approximately by grid lines 8E, 9, 10, and 11 as 'OPEN TO BELOW', indicating a double-height space. In contrast, the Structural plan specifies a solid floor system in this bay with '750 DP. OWSJ's' and a '62 CONC. TOPPING R/W 152x152 MW18.7/18.7 MESH MID-DEPTH' over metal deck.

Why it matters: Providing continuous floor framing in an area intended to be a multi-story open volume will severely impact the architectural design, equipment layout, and structural load distributions. Resolving this post-fabrication would result in massive waste and schedule delays.

Suggested next step: Please clarify if the area between grids 8E, 9, 10, and 11 is 'Open to Below' as shown architecturally, or a framed floor as shown structurally. Update the respective drawings to coordinate this space.

Summary: The Architectural Enlarged Slab Plan (10-23-040) locates the Genset Platform and Raft Slab between horizontal grids F and G. However, the Structural Slab & Foundation Plan (S2.1.4) shows the Genset and Genset Tank located significantly further south, below horizontal grid L near vertical grid 13.

Why it matters: A discrepancy of this magnitude (spanning multiple grid lines) indicates a major coordination failure between architectural utility layout and structural foundation planning. If uncorrected, this will lead to foundations being poured in the wrong location or utilities being routed to an area with...

Suggested next step: Please clarify the correct location for the Genset and Genset Tank. Architectural drawing 10-23-040 shows them between grids F and G, whereas Structural drawing S2.1.4 shows them below grid L. Which location is correct?

Summary: The structural framing plans locate a multi-story stairwell (identified as 'STAIR D') at grid intersection 6W and G. However, the architectural plans place an elevator shaft ('LIFT L1') at this exact same grid intersection (6W and G), and instead locate 'STAIR D' at grid intersection 1 and K. This indicates a severe spatial clash and a critical lack of coordination between the architectural and...

Why it matters: This conflict means the structural framing at grids 6W and G is detailed to support stairs, completely obstructing the required elevator shaft. Conversely, the architectural stairs at grids 1 and K currently lack the corresponding structural stair framing plans necessary for construction.

Suggested next step: Please confirm the correct grid locations for Stair D and Lift L1. Provide revised structural framing plans for the elevator shaft at grids 6W and G, and the missing structural stair framing plans for Stair D at grids 1 and K.

RFI draft: Please confirm the correct grid locations for Stair D and Lift L1. Provide revised structural framing plans for the elevator shaft at grids 6W and G, and the missing structural stair framing plans for Stair D at grids 1 and K.

Summary: The architectural West Elevation shows a steel door at ground level in the bay between grid lines 1 and 2, positioned adjacent to Grid 2. However, the corresponding structural elevation along Line K indicates that this same bay is filled with heavy, full-height diagonal cross-bracing (HSS305x305x9.5 and HSS254x254x8), with a lower diagonal bracing member landing directly at the base of Grid 2.

Why it matters: The structural cross-bracing will physically obstruct the architectural door opening, preventing its installation and blocking egress/access at this location. This constitutes a severe coordination failure between the building envelope and the primary steel frame.

Suggested next step: Please confirm if the structural bracing between grids 1 and 2 on Line K can be redesigned (e.g., as a moment frame) to accommodate the architectural door, or if the door must be relocated to an unbraced bay to avoid the bracing node at Grid 2.

RFI draft: Please confirm if the structural bracing between grids 1 and 2 on Line K can be redesigned (e.g., as a moment frame) to accommodate the architectural door, or if the door must be relocated to an unbraced bay to avoid the bracing node at Grid 2.

Summary: The architectural West Elevation depicts continuous vertical glazed bands (W29) and a steel man door located in the bay between grid lines 2 and 3W. Conversely, the structural elevation along Line K requires full-height diagonal cross-bracing (HSS305x305x9.5 and HSS254x254x8) spanning this exact bay.

Why it matters: Structural cross-bracing cannot occupy the same physical space as a continuous window curtain wall system and an access door. This will make the architectural facade unbuildable as designed.

Suggested next step: Review the structural bracing requirements between grids 2 and 3W on Line K. Can the structural bracing be reconfigured to clear the architectural openings, or do the windows/doors need to be relocated to a different bay?

RFI draft: Review the structural bracing requirements between grids 2 and 3W on Line K. Can the structural bracing be reconfigured to clear the architectural openings, or do the windows/doors need to be relocated to a different bay?

Summary: The architectural West Elevation features a large bifold door with an integrated man door (Keynote 24) located at ground level between grid line 7W and grid line 9. The structural elevation for Line K shows diagonal cross-bracing (HSS305x305x9.5 and HSS254x254x8) completely obstructing this same bay.

Why it matters: A large bifolding door requires an entirely clear and unobstructed span to open and operate. The presence of primary steel cross-bracing directly across this bay creates a hard physical clash.

Suggested next step: The structural bracing between grids 7W and 9 on Line K conflicts directly with the architectural bifold door (24). Please provide a structural redesign (e.g., using a moment frame instead of X-bracing) to accommodate this large envelope opening.

Summary: The Architectural and Structural plans contradict each other regarding the use of the roof bay between Grids 9 and 10. The Structural 'ROOF FRAMING PLAN - WEST' explicitly locates multiple mechanical units (e.g., '1000 KG. MECH UNIT') and their supporting framing within the bay between Grids 9 and 10. In direct conflict, the Architectural 'ROOF PLAN - ZONE 4' designates this exact same area (Gr...

Why it matters: If mechanical units and their structural framing are installed in the bay between Grids 9 and 10 as per the structural drawings, they will physically clash with the solar panel array designed for this space in the architectural layout. The design team must confirm the actual intended location for...

Suggested next step: Please clarify the intended location for the mechanical units currently shown between Grids 9 and 10 on the Structural Roof Framing Plan (S2.3.3). Architectural Roof Plan Zone 4 (A2.5.4) designates this area for PV Panels (Keynote 10) and shows mechanical equipment further wes...

Summary: The structural grid designation system is completely swapped between the Roof Plan (A2.5.4) and the Building Elevations (A4.0.1). On the Roof Plan, horizontal grid lines (which define the North-South axis) use lettered designations (e.g., F, G, K, L), while vertical grid lines (which define the East-West axis) use numbered designations (e.g., 7W, 12, 13). However, the Elevations apply these des...

Why it matters: This 90-degree inversion of the grid coordinate system between plan and elevation views is a major discrepancy that will cause significant layout errors during structural framing and foundation work. Furthermore, the explicit cross-reference marker '4 / A4.0.1' on the Roof Plan points to the West...

Suggested next step: Please clarify the correct coordinate system for the structural grids. Should the lettered grids (A-L) denote the longitudinal or transverse axis? Please update either the plans or the elevations to ensure consistent grid designations are used across all drawing views.

Summary: Detail 6 on sheet A2.6.2 (STAIR SECTION - GL F/12) displays a multi-story enclosed stairwell named 'STAIR E' located at Grid 12, originating at Level 1 and extending to Level 3. However, the Level 1 Enlarged Plan for Zone 2 on sheet A2.1.2 shows no interior stairwell shaft at Grid 12 near the southern exterior wall (Grid F). Instead, the floor plan indicates that this exact location is occupied...

Why it matters: The omission or mislocation of a 3-story egress stairwell is a major architectural and structural coordination issue. If the stairwell is required at Grid F/12, it will drastically alter the layout of the vestibule and syrup pickup areas, and require substantial floor framing changes. If the stai...

Suggested next step: Please clarify the location of STAIR E. Section 6/A2.6.2 indicates it is at Grid F/12, but the Level 1 Enlarged Plan (A2.1.2) shows occupied spaces (Vestibule 117 and Syrup Pickup 141) at this grid intersection with no interior stair shaft. Confirm the correct location of STAI...

Summary: Drawing S5.0.2 explicitly calls out diagonal cross-bracing members 'HSS254x254x8 Tf=Cf=1240 kN' above Level 3 (between LEVEL 3 and LEVEL 4) in the bay between grids 7W and 9. This requires an upper brace to connect to the column node at Grid 7W, Level 3. However, the specific connection detail for this node (S2.0.1 Detail 1 at 19.650 LEVEL 3) only shows a single diagonal brace framing in from b...

Why it matters: If the upper diagonal brace is omitted from the Level 3 connection detail, the connection engineer will not design the gusset plate to accommodate the 1240 kN loads from the Level 4 brace. This will result in a critical structural omission during fabrication and make it impossible to erect the up...

Suggested next step: Please clarify the bracing arrangement at Grid 7W, Level 3. Should S2.0.1 Detail 1 be updated to include the upper diagonal brace (HSS254x254x8) continuing to Level 4 as indicated on the S5.0.2 elevation?

RFI draft: Please clarify the bracing arrangement at Grid 7W, Level 3. Should S2.0.1 Detail 1 be updated to include the upper diagonal brace (HSS254x254x8) continuing to Level 4 as indicated on the S5.0.2 elevation?

Summary: The Foundation Plan (S2.0.1) dimensions Raft Pad R1 as 6000x3000mm (3000mm horizontally and 1500mm vertically from the centerlines). However, the specific 'RAFT PAD PLAN - TYPE R1' detail on S7.0.3 dimensions the pad as 7200x7500mm (3600mm horizontally and 3750mm vertically from the centerlines).

Why it matters: A dimensional discrepancy of this magnitude will severely impact excavation planning, concrete volume estimations, rebar detailing, and spatial coordination with adjacent structural footings or underground utilities.

Suggested next step: Please clarify the correct dimensions for Raft Pad Type R1. Should the foundation plan footprint (6000x3000mm) or the S7.0.3 detail footprint (7200x7500mm) govern?

RFI draft: Please clarify the correct dimensions for Raft Pad Type R1. Should the foundation plan footprint (6000x3000mm) or the S7.0.3 detail footprint (7200x7500mm) govern?

Summary: The Foundation Plan (S2.0.1) dimensions Raft Pad R2 as 6000x3000mm (3000mm horizontally and 1500mm vertically from the centerlines). In contrast, the 'RAFT PAD PLAN - TYPE R2' detail on S7.0.3 dimensions the pad as 7200x4200mm (3600mm horizontally and 2100mm vertically from the centerlines).

Why it matters: Constructing the pad to the incorrect size could result in critical structural load failures or field clashes. The discrepancy fundamentally affects foundation footprint limits, rebar mats, and concrete ordering.

Suggested next step: Please confirm the required dimensions for Raft Pad Type R2. Is it 6000x3000mm as shown on the foundation plan, or 7200x4200mm as shown on the S7.0.3 detail?

RFI draft: Please confirm the required dimensions for Raft Pad Type R2. Is it 6000x3000mm as shown on the foundation plan, or 7200x4200mm as shown on the S7.0.3 detail?

Summary: The Foundation Plan (S2.0.1) shows Raft Pad R3 with dimensions of 1500mm from the centerlines (resulting in a 3000x3000mm pad). Conversely, the 'RAFT PAD PLAN - TYPE R3' detail on S7.0.3 dimensions the pad as 2100mm from the centerlines (resulting in a 4200x4200mm pad).

Why it matters: The contradiction in foundation sizes between the general plan and specific details will lead to incorrect material orders, improper excavation areas, and possible insufficient load-bearing capacity if the smaller size is mistakenly built.

Suggested next step: Please clarify the intended dimensions for Raft Pad Type R3. Should it follow the 3000x3000mm footprint shown on S2.0.1 or the 4200x4200mm footprint shown on S7.0.3?

RFI draft: Please clarify the intended dimensions for Raft Pad Type R3. Should it follow the 3000x3000mm footprint shown on S2.0.1 or the 4200x4200mm footprint shown on S7.0.3?

Summary: Both drawing sheets S7.0.2 and S7.0.5 contain a detail explicitly labeled as Section 1 on sheet S2.0.2 (1/S2.0.2), but they depict entirely different structural conditions. The detail on S7.0.2 shows a stepped retaining wall with guardrail posts, whereas the detail on S7.0.5 shows a straight foundation wall connecting to an apron slab.

Why it matters: Having two completely different structural details share the exact same reference identifier is a critical drafting error. It creates severe ambiguity during construction, as it will be impossible to determine which of these details applies when 1/S2.0.2 is called out on the plans.

Suggested next step: Please clarify which detail is the correct Section 1/S2.0.2. Provide a unique detail number and sheet reference for the other section, and update all corresponding plan callouts accordingly.
