Why it matters: Addressing this before construction prevents rework and supports code compliance.

Suggested next step: Review drawings and specifications to resolve before construction.

RFI draft: Please clarify: Drawing Index Audit: 4 missing, 8 mismatched out of 50 sheets

Summary: Sheet C1.07 plan view notes the end of Drain G at STA 8+46.22 with "HIGH POINT ELEV: 855.0" and references continuation as Drain H on sheet C1.08. Sheet C1.08 plan view notes the end of Drain H at STA 2+83.58 with "HIGH POINT ELEV: 855.0" and references back to Drain G on C1.07. These two stations represent the same physical high point where both drains terminate. However, the longitudinal prof...

Why it matters: This 300-foot elevation error at the critical high point where Drain G and Drain H meet could cause significant confusion during grading and earthwork operations. If a contractor were to interpret the plan note literally, it would imply a completely different grade than what the profiles depict. ...

Suggested next step: Please clarify the HIGH POINT ELEV noted on the plan views of both C1.07 (STA 8+46.22, SD-G) and C1.08 (STA 2+83.58, SD-H). The plan views indicate 855.0, while the corresponding profile flowline elevations show 555.00 at both stations. Please confirm the correct high point el...

Summary: Both Sheet C1.03 and Sheet C1.04 list the Easting coordinate for BM #2 as E: 2541458.81. However, all other project benchmarks have Easting values in the 2580000–2582000 range (BM #1: E: 2582078.66, BM #3: E: 2581018.28, BM #4: E: 2580970.72). BM #2's Easting of 2541458.81 is approximately 40,000 feet away from the cluster of other benchmarks, strongly indicating a typographical error where the...

Why it matters: Survey control benchmarks are the foundation for all site layout and grading work. An incorrect Easting coordinate (a difference of approximately 40,000 feet) would cause catastrophic misalignment of any construction work referenced to BM #2. Since the error appears on both sheets, there is no co...

Suggested next step: Please confirm the correct Easting coordinate for BM #2. Both Sheets C1.03 and C1.04 show E: 2541458.81, but all other project benchmarks have Easting values in the 2580000–2582000 range. It appears the '4' in '2541458.81' may be a typographical error and should read '2581458....

RFI draft: Please confirm the correct Easting coordinate for BM #2. Both Sheets C1.03 and C1.04 show E: 2541458.81, but all other project benchmarks have Easting values in the 2580000–2582000 range. It appears the '4' in '2541458.81' may be a typographical e...

Summary: Sheet C1.03 lists BM #2 with Northing "N:7110251.54", but sheet C1.06 lists BM #2 with Northing "N: 7102051.54". Since both are labeled BM #2, these coordinates cannot both be correct for the same control point.

Why it matters: If construction staking uses the incorrect BM #2 coordinate, site layout and as-built elevations/locations can be offset, impacting storm drain alignment, grading, and record documentation. This can also create conflicts between survey control used by different contractors/subs.

Suggested next step: Confirm the correct BM #2 coordinate (Northing/Easting/Elevation) and revise the benchmark block so C1.03 and C1.06 match. Provide clarification on which benchmark set governs for construction staking.

RFI draft: Confirm the correct BM #2 coordinate (Northing/Easting/Elevation) and revise the benchmark block so C1.03 and C1.06 match. Provide clarification on which benchmark set governs for construction staking.

Summary: Sheet C4.00 Note 6 specifies the water main as 'PVC AWWA C-900 (DR-10)', while Sheet C4.01 Note 6 specifies 'PVC AWWA C-900 (DR-18)'. Sheet C4.02 General Note 1 further confirms DR-18, stating 'ALL WATER LINES SHALL BE C-900 DR-18, PRESSURE CLASS 150 PVC PIPE'. The Culleoka WSC Water Line Specifications table on C4.02 also lists DR 18 for standard carrier pipe. DR-10 and DR-18 have different wa...

Why it matters: The dimension ratio directly determines pipe wall thickness and pressure class. DR-10 pipe has a thicker wall and higher pressure rating than DR-18, and is significantly more expensive. This conflict will cause confusion during material procurement and could lead to installation of pipe that does...

Suggested next step: Please clarify the correct dimension ratio for the 8-inch PVC water main: DR-10 as shown in Note 6 on Sheet C4.00, or DR-18 as shown in Note 6 on Sheet C4.01, General Note 1 on Sheet C4.02, and the Culleoka WSC specifications table on Sheet C4.02. Please revise all affected sh...

Summary: For the same recorded instrument numbers, the overall layout and the plan/profile sheet list different easement widths. The sanitary sewer easement for INST. NO. 20210308000455720 is shown as 20' on C4.00 but 10' on C4.01. The CWSC waterline easement for INST. NO. 20210308000455710 is shown as 10' on C4.00 but 15' on C4.01.

Why it matters: Easement width controls where utilities may be legally installed. Conflicting easement limits can cause the waterline to be placed outside the correct easement, leading to redesign, permitting issues, or needing additional easement acquisition.

Suggested next step: Confirm the correct recorded easement widths for INST. NO. 20210308000455720 and INST. NO. 20210308000455710, and revise C4.00/C4.01 so easement widths match the recorded documents.

Summary: The Reinforcement Schedule on detail 1/S5 includes a row listing "COVER | 0"", indicating zero inches of concrete cover for the junction box elements. The project general notes require a minimum of 3" cover for concrete deposited directly against ground (base slab) and 2" for all other elements (walls, top slab). A specified cover of 0" directly contradicts these requirements and conflicts with...

Why it matters: Zero concrete cover would leave reinforcement directly exposed, resulting in immediate corrosion, loss of bond, and potential structural failure. Even if this is a typographical error in the schedule, it creates a conflicting instruction on the construction documents that could lead to misinterpr...

Suggested next step: Request the engineer clarify and correct the concrete cover dimension shown in the Reinforcement Schedule on 1/S5. The schedule currently indicates "COVER 0"", which contradicts the general notes requiring 3" for concrete against ground and 2" for all other cover. Please confi...

Summary: The reinforcement schedule on this sheet lists concrete cover as 0 inches. The specifications require minimum concrete cover of 3 inches for concrete deposited directly against ground and 2 inches for all other cover, so 0 inches directly contradicts the specified minimum cover.

Why it matters: Zero cover would leave reinforcement at the surface, creating major durability and corrosion risk and likely failing inspection/acceptance. It also undermines structural performance assumptions tied to bar development and protection.

Suggested next step: Confirm the required concrete cover for the junction box top slab, bottom slab, and walls, and revise the reinforcement schedule to meet the specified minimum cover (3" against ground and 2" otherwise), or provide a project-specific exception if intended.

RFI draft: Confirm the required concrete cover for the junction box top slab, bottom slab, and walls, and revise the reinforcement schedule to meet the specified minimum cover (3" against ground and 2" otherwise), or provide a project-specific exception if i...

Summary: The drawing's reinforcement schedule explicitly states the concrete cover is 0 inches. The specification requires minimum concrete cover of 3" when concrete is deposited directly against ground and 2" for all other cover. A 0" cover directly contradicts these minimum cover requirements.

Why it matters: If built with 0" cover, reinforcing steel would be exposed or effectively unprotected, increasing risk of corrosion, spalling, and noncompliance with the structural concrete requirements, potentially leading to premature failure and rejection during inspection.

Suggested next step: Confirm the required clear cover for the junction box top slab, walls, and bottom slab, and revise the reinforcement schedule to meet or exceed the specified minimum cover (3" where against ground; 2" elsewhere). Clarify whether the schedule 'COVER' entry is intended to be a m...

RFI draft: Confirm the required clear cover for the junction box top slab, walls, and bottom slab, and revise the reinforcement schedule to meet or exceed the specified minimum cover (3" where against ground; 2" elsewhere). Clarify whether the schedule 'COVE...

Summary: The drawing’s reinforcement schedule explicitly states the concrete cover is zero, which contradicts the specification’s required minimum concrete cover (2" typical, 3" when deposited directly against ground).

Why it matters: Zero cover would leave reinforcing at the surface, creating immediate constructability problems and high risk of corrosion/spalling and premature structural deterioration. This is likely to be rejected during inspection and could require demolition and replacement.

Suggested next step: Confirm the intended concrete cover for the junction box/manhole elements and revise the reinforcement schedule to match the specified minimum cover (or provide a project-specific cover requirement that supersedes it).

RFI draft: Confirm the intended concrete cover for the junction box/manhole elements and revise the reinforcement schedule to match the specified minimum cover (or provide a project-specific cover requirement that supersedes it).

Summary: The Benchmarks table lists BM #2 with Easting E: 2541458.81, while the other three benchmarks cluster tightly: BM #1 E: 2582078.66, BM #3 E: 2581018.28, and BM #4 E: 2580970.72. BM #2's Easting is approximately 40,600 feet (~7.7 miles) west of the other benchmarks. All four benchmarks should be in reasonable proximity to the project site, yet BM #2's northing (N: 7110251.54) remains consistent ...

Why it matters: Surveyors relying on BM #2 for control during layout and grading would either be unable to locate the benchmark at the stated coordinates (since no mag nail would exist ~7.7 miles away), or would introduce catastrophic positional errors if the coordinate were used without field verification. This...

Suggested next step: Please verify the Easting coordinate for BM #2 (currently shown as E: 2541458.81). Given that BM #1, #3, and #4 all have Eastings in the range of 2580970–2582079, BM #2 appears to have an erroneous Easting value. Please provide the corrected coordinate and confirm whether any ...

Summary: The Property Owner's Certificate signature block identifies the authorized signer as "ELAINE TORRES, OFFICER" for LGI Homes - Texas, LLC. However, the notary acknowledgment immediately below states "PERSONALLY APPEARED MARCOS A. MADRID, KNOWN TO ME TO BE THE PERSON WHOSE NAME IS SUBSCRIBED TO THE FOREGOING INSTRUMENT." Marcos A. Madrid is the Registered Professional Land Surveyor, not the owner...

Why it matters: A defective notary acknowledgment renders the owner's dedication legally unenforceable. The county clerk will reject the plat for recording since the notary attestation does not match the signatory on the owner's certificate. This would delay all permitting and lot sales until corrected and re-ex...

Suggested next step: Request that the owner's notary acknowledgment be corrected to reference Elaine Torres (or whichever officer actually executes the document on behalf of LGI Homes - Texas, LLC) instead of Marcos A. Madrid, and have the notary block re-executed.

Summary: The development schedule shows A-1 with 122 dwelling units and O-1 with 267 dwelling units (total 389); O-2 (Self Storage) and O-3 (Commercial) have no dwelling units. The calculation table at Calc Points 2 and 3 correctly carries 389 lots for the cumulative residential contribution. However, at Calc Point 4 (the combined outfall for all sewersheds A-1, O-1, O-2, O-3), the NUMBER OF LOTS jumps ...

Why it matters: An inflated design flow (832 GPM vs. an expected ~490 GPM) directly affects pipe sizing, slope requirements, and manhole spacing for the trunk sewer downstream of Calc Point 4. This could result in oversized infrastructure and unnecessary construction costs, or if the permitting authority challen...

Suggested next step: Clarify the correct NUMBER OF LOTS at Calc Point 4. The development schedule totals 389 dwelling units (122 for A-1 + 267 for O-1), consistent with Calc Points 1–3, but Calc Point 4 shows 1,045 lots. Confirm whether 389 is the correct value and whether the design flow, I&I, an...

Summary: The sheet is titled as the final plat for “SOUTH PARK MEADOWS”, but the certification text block states the “FINAL PLAT OF PRINCETON CROSSROADS SUBDIVISION”. These two subdivision/addition names conflict on the same page.

Why it matters: A plat with inconsistent subdivision/addition naming within its own title/certification blocks can be rejected during approval/recording and creates legal ambiguity about what is being dedicated/accepted.

Suggested next step: Confirm the correct subdivision/addition name for this plat and revise the certificate block language so it matches the sheet title everywhere it appears.

RFI draft: Confirm the correct subdivision/addition name for this plat and revise the certificate block language so it matches the sheet title everywhere it appears.

Summary: Sheet C1.03 (Detention Pond) directs the reader to sheet C1.04 for Drain 'B' details. However, sheet C1.04 is titled 'STORM DRAIN PLAN AND PROFILE DRAIN 'A' & 'A1'' and contains only information for Storm Drain A, A1, and A2. There is no Drain 'B' information on C1.04. The cross-reference is either pointing to the wrong sheet or Drain 'B' details are missing from the referenced sheet.

Why it matters: A contractor following this reference would be unable to locate the plan, profile, pipe sizing, structure details, and invert elevations for Drain 'B'. This could delay construction of the drainage outfall from the detention pond and may affect stormwater management permitting if Drain 'B' design...

Suggested next step: Please clarify which sheet contains the Drain 'B' plan and profile. The note on C1.03 references sheet C1.04, but C1.04 only contains Drain 'A' & 'A1'. Is Drain 'B' located on a different sheet, or should C1.04 be revised to include Drain 'B'?
