What Groundbook found in one real drawing set and its specs

G1.11 marks an accessible path through the paved corridor east of the tennis courts and south past the fountain. At that location, C4.1 shows a 6.5% slope along the corridor and a 2.5% slope across the north–south branch beside the fountain.

G1.11 requires this path to have a running slope no steeper than 1:20 (5%) and a cross slope no steeper than 1:48 (about 2.08%). The grading shown at this part of the route conflicts with those stated limits.

H/D2.2 shows a 12-inch retaining wall with a 3-foot maximum height and sends its reinforcement and footing to the structural drawings. D2.5’s B-B′ elevation gives a top of 138.00 feet and a bottom of 134.50 feet at one step; C-C′ gives 138.50 and 135.00 feet at another, making both walls 3½ feet high.

C7.1 key 6 instead sends the 12-inch wall to H/D2.1, an 18-inch-maximum tall-curb detail. The available structural retaining-wall typical, 2/S5.02, shows an 8-inch wall with undefined “A” vertical bars; the structural foundation plan, notes and typical details do not resolve the 12-inch wall reinforcement.

A/D1.2 also shows 12-inch planter walls but leaves their footing reference as X/DX.X.

The footing schedule on D2.4 refers the 30-foot flagpole foundation to the structural drawings and the 40-foot foul-pole foundation to the netting manufacturer's drawings. The building structural sheets do not contain a flagpole foundation, and SFS-1/SFS-2 detail netting poles without identifying a foul-pole foundation. Detail A/D2.3 also refers the flagpole footing to those missing structural requirements.

On C5.1, the 12-foot JB04–JB03 pipe is labeled for a minimum 2% fall. Its endpoint inverts are 126.25 and 126.85 feet, which instead make it rise 5% in the indicated flow direction.

The next 18-foot pipe, JB03–CB01, also requires a minimum 2% fall. Its inverts of 124.50 and 124.60 feet instead make it rise 0.56%.

On C5.1, the 112-foot TDCB #01–JB #02 pipe requires a minimum 0.5% fall. Its inverts of 126.11 and 125.90 feet give only a 0.1875% fall.

On C5.2, the 151-foot COIT03–JB12 pipe requires a minimum 0.5% fall. Its inverts of 130.13 and 129.87 feet give only a 0.17% fall.

The C5.1 crossing table puts a 6-inch storm drain at invert 125.80 above the 2-inch water line at 125.40 at crossing 1. Their maximum clearance is (125.80 − 125.40) × 12 − 2 = 2.8 inches. At crossing 2, the water invert is 125.40 above a 12-inch storm drain at 124.05, giving at most 4.2 inches. Both values exclude pipe walls, which further reduce the gap, and are below the 6 inches required by Section 33 11 00, paragraph 3.04B.2.

E4.1 lists DP-A as Schneider NQ442L4C with an MH50WP enclosure. E0.2 requires NEMA 4X and schedules 14 three-pole lighting circuits, three single-pole circuits and one three-pole restroom feeder: 14 × 3 + 3 + 3 = 48 occupied pole spaces. The NQ442L4C data sheet provides 42 spaces, and the MH50WP data sheet gives a Type 3R/5/12 enclosure rating. Both selections differ from the panel schedule.

On E0.2, the one-line diagram labels the new main-switchboard breaker “400/3” and points to keynote 1. That same keynote specifies a new 250 A, three-pole breaker. These are different ratings for the same breaker.

Keynote 2 on E2.0 directs the contractor to E0.2 for conduit and conductor sizing. The E0.2 one-line diagram labels the new MSB-to-DP-A and downstream feeders only as "(N) FEEDER", without sizes. The E0.2 schedules and E0.3 sports-lighting feeder schedule do not identify sizes for the MSB-to-DP-A feeder or the restroom-panel feeder.

Detail 1/S5.22 calls for two anchor holes, while its plan shows an anchor at each of the four plate corners. The adjacent base-plate schedule also gives dimensions C, D and E that the detail does not identify. The schedule and complete base detail therefore leave both the anchor quantity and the application of those dimensions unresolved.

C7.1 key 18 sends baseball netting posts to K/D2.1 and the structural drawings. K/D2.1 shows the netting post surrounded by a widened concrete curb with 4-inch concrete margins and a transverse expansion joint. Detail 9/SFS-2 instead says not to encase the pole in the curb and requires a 1/2-inch to 1-inch gap filled with compressible material and sealant. The transverse joint in K/D2.1 does not show that separation between the pole and the surrounding curb.

A10.41 bases its 16-inch clip spacing on 24-gauge galvanized-steel panels at a 3.5:12 roof pitch. The roof plan on A2.12 shows 2.5:12 on both roof planes. Reference Section 07 41 13.16, 2.02.B.2 lists aluminum sheet panels, although thickness and other selections remain open. The printed anchorage criteria therefore differ from the roof plan and the material listed in the reference specification.

M0.02 schedules eight RHP-1 radiant panels at 375 W and 120 V each. E0.2 lists RHP-1 at 208 V and leaves its circuit field blank. The E0.2 equipment and PB-A panel schedules do not assign circuits to the eight heaters.

A9.11 schedules all thirteen gates at 8 feet high. C7.1 instead requires 7-foot single gates at G101, G103, G105, G107, G108, G109, G110 and G111; 12-foot double gates at G102, G104, G106 and G112; and a 10-foot double gate at G113.

The civil double gates are also 12 feet wide, but A9.11 gives each of their two panels a width of 3 feet 11 inches, totaling 7 feet 10 inches.

C7.1 also keys two additional pedestrian gates without separate architectural tags or schedule rows: one beside G101 and one at the east end of the middle tennis-court fence.

The SPORTS LIGHTING FEEDER SCHEDULE on E0.3 defines the circuits and conductors for the M-numbered lighting runs. Ten pole branches name contactors absent from their scheduled runs: for example, M11 serves T2/C2 but lists C1 and C13, while M17 serves A2/C14 but lists C9.

Eight connecting runs also omit contactors assigned to the poles downstream of them. The baseball and softball diagram labels M22, but the complete feeder schedule ends at M21.

Detail J/D1.1 places the irrigation mainline and power/data conduit 1 foot apart, center to center, beside the field-perimeter subdrain. The site conduit keynotes on E2.0 refer to detail 4/E4.1, which requires 3 feet minimum clear separation from a parallel pipe or conduit. The dimensioned shared-trench arrangement cannot provide that clearance.

Detail I/D1.1 labels a 4-inch existing rock base to remain and points to C/D2.2 as “synthetic turf over existing base.” That referenced detail instead shows a 5-inch permeable base and 1-inch composite layer over treated subgrade. The midfield subdrain detail therefore does not match the turf assembly it cites.

E/D1.1 also labels an “existing synthetic turf base” while pointing to that same new turf assembly.

C3.1 refers existing irrigation water lines and flow-sensor wiring to an irrigation plan, and the C7.1 material legend refers planting and stormwater-management areas to planting plans. Neither plan appears in the submitted 109-sheet drawing set. Sections 32 80 00 and 32 90 00 leave equipment and plant selections to the drawings, so the specifications do not replace those plans.

The A9.11 door schedule leaves the hardware-group column blank for all nine doors. General note 16 refers the hardware schedule to the specifications. The submitted specification has no hardware schedule or Section 08 71 00 to supply those assignments.

Framing-plan note 13 on S2.02 requires visually exposed steel to meet architecturally exposed structural steel (AESS) requirements. Section 05 12 00 refers those members to Section 05 12 13. The submitted specification contains no Section 05 12 13, and the inspected architectural and structural sheets do not provide the referenced AESS requirements.

Demolition note 7 on C3.1 requires 4-foot orange safety fencing secured with driven metal stakes around plants to remain. The same sheet’s tree-protection legend refers to Section 32 01 90. Paragraph 2.01A of that section requires 6-foot self-supporting chain-link fencing and expressly prohibits driven support posts.

At the northeast corner of the field, C3.2 groups protected-item keys B and CC with demolition keys 8 and 15 on one leader to the short angled fence/wall segment. B and CC require the existing fence and wall to remain and be protected; 8 and 15 require those same types of elements and their footings to be removed. The callout gives no separate limits for the opposite instructions.

Detail C, FOUL POLE - RIGHT FIELD, on D2.3 specifies a 40-foot foul pole integrated into the retaining wall. WALL ELEVATION - C-C′ on D2.5 labels that right-field wall pole 30 feet tall. The detail and wall elevation therefore require different heights for the same pole.

The CONCRETE JOINTS detail D on D2.1 specifies 24-inch smooth dowels at 36 inches on center in the expansion-joint sections. The CONSTRUCTION / EXPANSION JOINT plan in that same detail specifies those dowels at 18 inches on center. The plan and sections therefore require different dowel spacing for the expansion joints.

C7.1 material key 1 identifies the site trench drain as presloped and refers to detail M/D1.1. That detail is titled “NEUTRAL-SLOPED TRENCH DRAIN.” Specification Section 33 40 00 also specifies a presloped channel for trench drains outside a running track, so the drawing detail and referenced requirements do not agree on the channel type.

Detail 5/A10.41 shows a steel-pipe downspout with welded mounting tabs, and A5.11 calls it Schedule 40 metal pipe. Section 07 60 00, paragraphs 2.07B and 2.07C, describes downspouts formed from aluminum or coated-steel sheet. The drawing and specification describe different downspout construction.

P0.02’s ELECTRIC WATER HEATER SCHEDULE lists EWH-141 at 1,500 W total heating power, 208 V, single phase, and 25 A. For that resistive heating load:

Current = power ÷ voltage = 1,500 W ÷ 208 V ≈ 7.2 A.

E0.2’s ELECTRICAL EQUIPMENT SCHEDULE also lists 7 A full-load current. The 25 A entry does not agree with the scheduled total power and voltage.

E0.2’s LIGHTING FIXTURE SCHEDULE lists the same RNDS-2-L25/840-FXA-DIM-UNV model and 2,500-lumen output for C3 and P5, but gives 24 W for C3 and 3,257 W for P5. The P5 model and input-power entry are inconsistent.

CMU (concrete masonry unit) note 20 on S1.02 requires at least 8 inches of grout around embedded items within a block cell. S2.01 specifies 8-inch CMU walls, and S5.12 provides embedded-anchor details for those walls. An 8-inch clearance around an embed cannot fit within an 8-inch wall.

Detail 5 on S5.12 schedules eight headed anchors and a 21½-inch plate height for its W18 beam row. Its one-sided plate detail arranges the anchors in two columns at 8-inch vertical centers.

Eight anchors require four rows. With 8 inches between rows, the outer rows are 24 inches apart, exceeding the 21½-inch plate height before edge distances.

Detail 2 on SFS-2 schedules two tie spacings for both 40-foot netting-pole footing types: S1 at 4 inches and S2 at 9 inches. The section labels ties only with S1; it gives no S2 zone or transition point.

Detail 1 on S5.32 requires reinforcing angles for deck openings wider than 8 inches through 24 inches and refers to detail 2. Detail 2 gives angle sizes only for 12 < W1 < 18 inches and 18 < W1 < 24 inches. Openings wider than 8 inches through 12 inches, and the exact 18- and 24-inch widths, therefore have no angle size in the cited detail.

The lower section in B/D2.1 shows a 4-inch pedestrian concrete slab. It calls for 2½ inches of clear cover above the reinforcement and also requires the reinforcement in the middle of the slab. The middle of a 4-inch slab is 2 inches below its surface, so the stated clear cover cannot produce that placement.

The roof plans on S2.02 specify HSS (hollow structural section) beams, but framing note 10 directs typical beam-to-HSS-column connections to 1/S5.21. That detail is titled “WF BEAM TO HSS COLUMN” and connects a wide-flange beam web to a shear plate. Separate HSS connection details are present on S5.21, so the stated typical reference needs to identify the intended connection for these roof beams.

Wall section 4/A6.21 shows a CMU (concrete masonry unit) wall between Gender Neutral 147 and Common 153, but its head calls for 3/A10.11 and its base for 1/A10.11. Those details show a metal-stud head with a deflection track and a nonstructural metal-track wall base. A10.11 separately contains detail 11, titled CMU WALL BASE.

E2.0 refers the site pull boxes to detail 1/E4.1, which shows a 6-inch gravel base. Section 26 56 68, paragraph 2.2D, requires 12 inches of compacted aggregate beneath sports-lighting handholes. The referenced detail provides half the specified bedding depth.

The Fixture Type Summary on E5.1 lists six Cree OSQ fixtures at a color rendering index (CRI) of 70. Section 26 56 68, paragraph 1.2B, requires a CRI of 75 for the lighting system. The selected fixture rating is lower than that requirement.

P0.02’s PLUMBING FIXTURE SPECIFICATION & CONNECTION SCHEDULE describes L-1 as “COLD WATER ONLY” and gives no hot-water connection. P2.01 draws a 1-inch hot-water supply and 3/4-inch hot-water return loop at the group labeled “(3) L-1”. The fixture schedule and the drawn water-supply arrangement do not agree.

E5.4’s Egress grid reports a maintained horizontal average of 25.31 footcandles (fc), using 16 points at 10-foot spacing. Section 26 56 68, paragraph 1.2.A, specifies a 26 fc average target for that same 16-point, 10-foot grid. The submitted calculation is below the specified target.

G0.11’s CODES block identifies the 2025 California Building Code for the project. E0.1’s MEP COMPONENT ANCHORAGE NOTE instead directs component anchorage to the 2022 CBC. These are competing editions of the same code for work covered by the project’s stated code basis.

Detail 2/S5.01 requires E80-series electrodes for A706 Grade 60 reinforcing bars and E90-series electrodes for A615 Grade 60 bars. Section 03 20 00, paragraph 2.01M, instead specifies E70XX-series electrodes. The set’s stricter-requirement rule makes the drawing minimums govern, but the specification still names a lower electrode grade.

The structural-steel notes on S1.01 assign ASTM A500 Grade C round HSS a yield strength of 50 ksi. Section 05 12 00, paragraph 2.01A.5, assigns the same material 46 ksi. S2.01 uses round HSS for three columns, so the discrepancy applies to the building. The set’s stricter-requirement rule makes 50 ksi govern.

Detail 1/S5.22 calls for F844 washers above and below the column base plate. Section 05 12 00, paragraphs 2.01F.6d and 2.01F.7c, requires ASTM F436 hardened washers for anchor rods. The detail names a different washer grade from the specification. S1.01 makes the stricter requirement govern, but the base detail still names F844.

The D2.4 footing schedule specifies round 4-inch pipe posts for the 7-foot-high pedestrian gates. Section 32 31 13, paragraph 2.04C.4a, instead requires 4-inch square posts for pedestrian gates 8 feet high and under. Detail M/D2.4 also names latch CL-FULCRUM-SNG, while paragraph 2.02D.7c specifies STRONG-ARM-SNG.

Structural-steel note 6 on SFS-1 requires a TGIC polyester primer for exposed steel. Section 11 65 00, paragraph 2.02B.1b, requires a zinc gray epoxy primer for the netting poles. These are different primer systems for the same poles.

C7.3 refers the new sidewalk to the City concrete-work notes in D/D1.1. Note 13 requires broom texture along the sidewalk, while section 2003.5A of the City standard on D1.3 requires broom strokes perpendicular to the curb when a broom finish is used.

Note 9 of the concrete-work notes requires weakened-plane joints at least 1½ inches deep. Section 2003.6A of the City standard gives approximately one-fifth of the slab thickness—about 0.8 inch for the 4-inch sidewalk in F/D1.1.

The standards allow matching existing finishes or an approved direction, but the supplied offsite sheets do not identify which requirements govern these differences.

On C6.1, the fence line between the tennis-court rows is at northing 1102.81 feet, and the north edge of the southern court row is at northing 1084.81 feet. These coordinates give an 18-foot offset, but the dimension between the same lines reads 18 feet 2 inches.

H/D3.1 labels the flat mound surface 10 inches above home plate, but the note beside its descending elevation marks says those changes start from an area 9 inches above home plate. Note 3 gives a total elevation difference of 10 inches, with the final inch between the mound and home plate.

E/D4.2 connects the operating pressure indicator beside the control valve at the center supply header. Its callout points to L/D4.2, which requires one indicator per zone at the flush end. E shows the flush valves at the two outer exhaust headers.

In N/D1.1, section B–B′ calls for a light broom finish lengthwise on the concrete surround. Note 1 requires a medium broom finish lengthwise for the same concrete.

The finish-plan legend on A2.21 refers wall, base and floor finishes to a finish schedule. The room tags on that sheet leave those finish fields blank, and the submitted drawing set contains no finish schedule to complete them. The specification describes finish systems without assigning them to these room tags.

A2.11 uses wall-type marks AS4Z and ZM8Z. The wall-type legend on G0.11 points to A10.11, but that sheet contains typical details referring back to the plans without defining either mark. No definition of these marks was found in the submitted drawing set.

Detail B/D2.1 refers the limits of chemical treatment to a “Chemical Treatment Plan.” No sheet with that title or an identified substitute is provided in the 109-sheet drawing set. C7.1 and C7.2 identify treated surface types, but do not resolve that plan reference. The earthwork specification incorporates a separate geotechnical report, which was not supplied for this review.

C4.1 directs grading within the city right of way to the offsite plans. C0.0 lists C4.3 as “GRADING PLAN (NOT INCLUDED)”; the submitted offsite sheets contain no grading plan for the new sidewalk and curb-ramp work.

On C3.1, boxed key T points to two existing curb ramps at the northwest street corner. The protected-or-relocated-items legend defines T as “NOT USED.” General note 5 says existing items remain unless otherwise noted, but these two specific leaders have no defined instruction.

Note 1 in the Signage Materials and Color Keynotes on A10.81 directs sign mounting to detail 16/A10.81. Detail 16 is Fire Rated Wall Identification in Concealed Spaces; the sign-attachment instructions are in detail 6, Sign Mounting.

Concrete note 1 on S1.01 directs the 28-day compressive-strength requirement to note 28. Note 28 only requires 48-hour notice before concrete placement; the concrete strengths and mix properties are in note 32.

A2.11 uses keynote 34.01 at the three lavatory approach spaces and defines it as a 30-by-48-inch accessible clear space, referring to 3/A10.71. That detail is titled “DOOR LANDING AND CLEARANCES” and depicts door swings and latch-side landing dimensions, rather than the lavatory approach referenced by the keynote.

Note 3 in F/D2.2 sends the reader to the synthetic-turf notes in A/D2.2. Detail A is Asphalt Paving; the Synthetic Turf Notes are detail B on the same sheet.

The basketball striping detail F/D2.3 points the basketball post to Footing Schedule B/D2.4. That schedule lists fences, gates, netting, foul poles and the flagpole, but no basketball post. The basketball footing is shown in B/D2.3.

The overflow-riser callout in A/D1.2 points to detail E on the same sheet. That slot is blank. The overflow riser with grate/standpipe is shown in detail D.

Detail E, PADDING ATTACHMENT - WALL / CHAIN LINK FENCE, on D2.3 directs the Z-clip mounting to 7/S8.1 and the home-run-wall padding condition to F/D2.2. The submitted drawing inventory and structural index contain no S8.1. F/D2.2 is SYNTHETIC TURF ON CONCRETE PAVING, so it does not show the referenced wall-padding condition. D2.5 also leaves the wall-padding attachment reference as “DETAIL XX, SHEET XX.”

Detail A/D4.1 refers the tree grate to material plan CS-702. The submitted drawing set has material plans C7.1 and C7.2, but no CS-702. C7.1 item 32 refers back to A/D4.1, so the reference does not lead to additional grate information.

The wall sections on A6.21 use keynote codes 05.01, 05.02 and 08.61. The sheet’s keynote list is empty, and no definition of these three codes was found elsewhere in the submitted drawing set.

On the south elevation of A5.11, the 08.31 leader points to the painted mascot and the 09.87 leader points to the clerestory panel. The keynote list defines 08.31 as the Kalwall panel assembly and 09.87 as the wall mural. The two leaders identify the opposite elements.

In 8/A8.12, GN149 west elevation, two 10.20 leaders point to the bench and the masonry wall. The same sheet defines 10.20 as a UNISEX RESTROOM ID WALL SIGN. These leaders therefore assign a sign to two different building elements.

The west and east elevations on A5.12 use keynote 07.82 for downspout components. The same sheet defines 07.82 as GUTTER; A5.11 separately defines 07.84 as DOWNSPOUT.

In the typical mounting-height details on A10.71, the wall-mounted water closet is labeled 22.07. The same sheet defines 22.07 as an accessible hi-lo drinking fountain.

The service sink is labeled 22.09, but that keynote is defined as an accessible bottle filler.

The west-side section callout on A2.11’s FLOOR PLAN prints A6.12 and A6.14 over each other beneath section number 1. The overlapping last digit makes the destination sheet ambiguous.

Details 4, EXTERIOR DOOR HEAD/ JAMB @ CMU, and 5, EXTERIOR DOOR HEAD @ LOUVER, on A10.21 each state “FOR FRAME DIMENSIONS AND DETAIL, SEE”. In both details, the note ends without a detail number, sheet number or reference bubble.

M0.02 refers the exhaust fan to X/M5.01 for mounting and X/M6.01 for controls, and the radiant panels to --/M5.01 for mounting. P0.02 refers the water heater and expansion tank to x/P5.01.

The submitted 109-sheet drawing set was checked: M5.01, M6.01 and P5.01 are absent, and the detail numbers remain placeholders. These schedule references cannot be followed.

G0.11’s SHEET INDEX lists the offsite detail sheets as D1.01–D1.03 and the structural cover as S0.00. C0.0’s offsite index uses D1.1–D1.3, and S1.00’s structural index identifies the cover as S1.00. E0.1’s electrical index omits the bound sheets E0.3, E3.1, E3.2, E4.1, E4.2 and E6.1, all listed in G0.11. It also lists E5.5, which is absent from G0.11 and the submitted 109-sheet set. These lists give inconsistent identifiers and coverage for the submitted drawings.

The cold-formed steel member legend on S1.02 says thickness callouts are in “1/1000 MILS,” although its next line correctly defines 1 mil as 1/1000 inch.

Its 1⅝-inch width example also incorrectly multiplies 1.625 by 1/100 instead of converting a hundredths-of-inch designation.

Note 1 on both C4.1 and C4.2 leaves blank the source on which the existing grades are based. C1.1 names the aerial and topographic survey provider, but the grading notes do not identify their selected source.

Synthetic-turf note B-5 on D2.2 says quick couplers are the only utilities to be cut through the turf. Note F-2 on the same sheet permits both quick couplers and cleanouts. The notes give different rules for cleanout access.

The calculation summary on E5.2 reports maximum vertical illuminance for "Project Spill @ 5ft". Section 26 56 68, paragraphs 1.3B and 1.3C, require the vertical spill-light scan at 3 feet above grade. The 5-foot result does not demonstrate compliance at the specified height.

The Softball Illuminance report on E5.3 uses 73 outfield calculation points. Section 26 56 68, paragraph 1.2A, requires at least 75 outfield grid points. The submitted calculation therefore does not use the specified minimum sampling count.

A2.11 and the restroom elevations on A8.11–A8.13 use keynote 12.63 for furniture and refer to a “FURN SCHEDULE.” No furniture schedule is included in the submitted drawing set. The tagged furniture therefore cannot be resolved through the stated reference.

E3.1 and E3.2 label their photometric site views at 1/2 inch = 1 foot. The plotted court geometry is about one-twelfth that scale. For example, the 78-foot tennis court dimensioned in G/D2.3 is drawn about 3.25 inches long on E3.1; at the stated scale it would be 39 inches long.

E3.1 also shows the same courts rotated about 79 degrees from E2.1, while both views show the same unqualified north arrow pointing up the page. The arrows therefore indicate different north directions for the same site without identifying a different north basis.

G/D4.2, “Techline Start Connection (PVC to Tee),” shows the upper fitting joining dripline to the left, right and below. Its leader calls that three-way fitting “TECHLINE ELBOW.”
