Question Question from Morgan Gross Rockford Construction on Tuesday, Oct 20, 2026 at 09:53 AM EDT

1. Turf base responsibility: 32D includes base, flat drain and fines inside the anchor; BP 31 excludes them; 32D Alt 4 deducts it if "BP 31A" provides it. Confirm base is in our base bid and identify BP 31A. Disregard Alternate 4 language.

Follow Scope.

2. Existing stadium turf removal: Is removal/disposal in base bid or only 32D Alt 5 (also BP 2 Alt 3)? Alternate has been requested from BP 32D, BP 31, and BP 2. It will be assigned at award. The schedule shows turf removal Mar 22–Apr 2, 2027. Does the existing field have a shock pad? NO.

3. Existing stadium base rework: Who excavates ±2" of existing aggregate and salvages ±1" of fines (L1.1 Note 2, Detail 15 LD1.02)? How much new stone is assumed? Will the Owner test the reworked base? I have asked for clarification on this from IDS.

4. Wood nailer: The drawing asks for an allowance; the bid form asks for a $/LF unit price. Which governs, and what LF/allowance amount should all bidders carry? Provide cost per LF.

5. Missing specs: 03 3053 Concrete Turf Anchor and 27 5119 Field Utility Boxes are in the TOC but not in the spec book. Please issue them and confirm who furnishes boxes and turf-filled lids (32D lists 27 5119). Spec section 25 5119 has been requested. Per BP 32D Scope of work 27 5119, furnish and install all field utility boxes both inside and outside of turf areas.

6. Proposal exceptions: 32 1818 says exceptions go in the proposal, but the Procore form can't be qualified. How do we submit exceptions and voluntary alternates? Exceptions will be allowed. Voluntary alternates can be added to the voluntary alternate section of the bid form.

7. Batting cage: Architect Alt 5 (second bay) has no line on the 32D form — add one? The schedule installs batting cage turf Apr 21–22, 2027, before turf delivery May 11–14. Alternate Line is being added to the Bid Form.

8. Bullpen alternate: Confirm Alt 3 product (32 1809 coated-back bullpen turf), whether turf covers the mounds, and the area. Reference LD1.07 detail 7.

9. Testing costs: 32 1123 sieve analysis per 150 tons "administered through the project" — who pays? Above testing is provided by owner testing consultant and paid for by owner. Which compaction/permeability tests are by the Owner's agency? Permeability Testing is by BP 32D and witnessed by owners representatives.

10. Subgrade tolerance: BP 31 delivers ±0.05'; 32 1123 requires ±0.02'. Who corrects to ±0.02'? Per Common Scope of work BBB. All work shall be in strict accordance with the drawings and specifications; therefore All grading shall be +/-

0.02 foot. BP 31 shall meet the grading tolerance as specified in section 32 1123 as applicable per that section

11. Maintenance equipment: One set for the project or one per field? Provide per specification.

12. Staging: Where can we stage turf rolls and stockpile stone/infill, given the one-week-of-material limit? Reference

BID REQUEST FOR INFORMATION

Northview Public Schools | Athletics Stadium Additions & Renovations Bid Category #32D - Synthetic Turf and Base

To: Dan Korcek, Rockford Construction | dkorcek@rockfordconstruction.com

From: Ken Hutchinson | AstroTurf Great Lakes

Date: October 14, 2026 | RFI No.: RCCI to assign

Subject: Bid scope, document conflicts and pricing clarifications

Please provide written clarification of the following items by addendum or bid clarification so all bidders carry a consistent scope. References to manual/specification pages are original PDF page numbers. Drawing references use sheet/detail numbers.

1. Existing turf/infill removal and shock-pad clarification Manual p.23, Demolition Alternate 3; p.73, #32D Alternate 5; drawing L1.1 replacement notes.

Existing turf and infill must be removed. Please clarify whether the existing shock pad must also be removed and disposed of or is to be retained, and identify the affected fields/areas. Selective Demolition Alternate 3 and #32D Alternate 5 both carry existing turf/shock-pad removal. Identify the responsible contractor and confirm whether #32D carries this work in the base bid or as an additive alternate.

2. Stadium aggregate removal, salvage and adjustment L1.1 replacement note 4; LD1.02 detail 15; manual pp.60-62 and 71.

L1.1 requires excavation of approximately 2 inches of aggregate and salvage of approximately 1 inch of fines. Confirm who removes, stores, reuses and disposes of these materials; the required final aggregate elevations after the new pad is added; and the bid basis for supplemental stone or unsuitable existing material. Identify whether the indicated work is in #32D base or another category.

3. Band-field existing base removal alternate Manual p.62, Sitework Alternate 5; pp.70-73, #32D.

Sitework Alternate 5 prices complete removal of existing band-field base and drains, with disposal and access-road reuse options. Confirm the base-bid treatment of existing band-field base/drainage if that alternate is not accepted, and the demolition/reconstruction limits to be included by #32D.

4. Base/drainage transfer under #32D Alternate 4 Manual p.73, Alternate 4; Section 32 1123, 1.3.F and 3.1.

Define precisely what transfers to BP31A under Alternate 4: furnishing versus installation, stone/fines, geotextile, perimeter and flat drains, excavation/backfill, testing, survey/string checks and corrections. Confirm the work retained by #32D and the acceptance/warranty responsibilities for a base built by others.

DKorcek Text Box RFI was written several days ago requesting clarification on this item

DKorcek Text Box Clarification was requested if the entire base/drainage is to be removed. Currently, it is anticipated that the new storm drainage will be cutting through the existing Band field storm drainage and therefore could cause some settlement of base if washed into existing storm piping. Alternate is requested if Engineer advises that complete removal is not required. BP 32 D is to provide complete base/drainage layer system and drainage per scope of work.

DKorcek Text Box BP 32D shall disregard Alternate 4. BP 32D shall provide complete drainage per 32D scope of work.

DKorcek Text Box Existing Shock pad shall be removed and disposed of as a part of the alternate.

Alternate price is requested of both trades. It will be assigned the trade at award.

5. Subgrade handoff tolerance and deficient soils Manual p.60, Sitework item 20; p.71, Substrate items 1 and 5; Section 32 1123, 3.1.I.

Sitework hands over subgrade within +/-0.05 foot at every point; the aggregate specification requires +/-0.02 foot before the next layer. Confirm which trade brings subgrade to the tighter tolerance and performs the specified scarification/recompaction, proof-roll corrections and undercut/replacement before #32D acceptance. Define responsibility for later settlement caused by utility-trench backfill by other trades.

6. Drainage connection limits Manual p.61, Sitework item 47; p.71, Substrate item 3; p.73 exclusions; Section 33 4615.

Sitework extends storm drainage through the turf anchor a minimum of 5 feet, while #32D connects at the turf perimeter. Confirm the exact handoff locations and responsibility for the overlapping 5 feet, fittings, collector connections, trench excavation/backfill and testing. Confirm Section 33 4615 governs #32D interior drainage even though omitted from its listed sections.

7. Missing Field Utility Boxes section and scope split Manual p.70 lists 27 5119; specifications contents p.6; LD1.02 details 17-20; E7.1 detail 8.

Please issue Section 27 5119, which is listed but has no body in the supplied specifications. Identify who furnishes and installs outer field utility/communication boxes, goal-post access boxes, manhole covers and quick-coupler boxes, including supports, concrete backing, drainage connections and turf-covered lids. E7.1 assigns internal electrical components to electrical; confirm the outer-box quantities/models and #32D limits.

8. Concrete anchors and wood nailer allowance Manual pp.26 and 73; L1.1 replacement note 1; LD1.01 detail 19.

Concrete scope includes turf anchors and #32D excludes concrete, but #32D breakdowns group turf anchors with base/drainage. Confirm concrete is excluded from #32D pricing. L1.1 requests a nailer replacement allowance while #32D requests only a $/LF unit price. Provide the allowance quantity or dollar amount for the base bid and define measurement/payment for additional approved replacement.

9. Bullpen turf alternate assembly Manual p.73, #32D Alternate 3; LD1.07 details 7 and 8; Section 32 1123, 3.2.E.

The bullpen alternate shows 6 inches of aggregate while Section 32 1123 requires an 8-inch minimum full profile. Confirm the required base thickness, turf product/pile height, infill and pad requirements for both double bullpens, including mound transition limits. Confirm earthwork and concrete adjustments remain with their respective trades and are coordinated with this alternate.

10. Shock pad at stadium south D-zone and band field Manual p.71; LD1.01 detail 15 and auxiliary/band field details.

LD1.01 detail 15 labels the south D-zone pad optional while #32D includes a stadium pad. Confirm that the pad is included throughout the south D-zone. Auxiliary-only pad notes at the auxiliary/band details otherwise indicate no band-field pad; confirm this interpretation.

DKorcek Text Box Per Common Scope of work BBB. All work shall be in strict accordance with the drawings and specifications, therefore All grading shall be +/-0.02 foot. BP 31 shall meet the grading tolerance as specified in section 32 1123 as applicable per that section

Is maintenance equipment required?

12. Field markings and flag football Section 32 1818, 2.2.C.8.e; LD1.11, LD1.12 and LD1.13.

The flag-football entry is blank. Confirm whether flag-football markings are required; if so, issue colors, widths, dimensions and applicable fields. Confirm the issued graphics sheets define the base-bid markings and provide editable logo/lettering artwork before shop drawing preparation.

13. Testing scope, payer and minimum locations Section 32 1123, 1.3.D-F, 1.5.D and 2.1.C; Section 32 1818, 1.4.E and 1.7; manual p.72.

Please identify who contracts and pays for subgrade/aggregate compaction, permeability, sieve tests and planarity/string checks, because the base sections refer to Owner-selected/provided testing while #32D includes testing. Confirm whether eight base permeability locations and ten turf G-max/HIC locations apply separately to each field, and identify any required warranty-period testing frequency and payer. Confirm HIC applies only to padded areas.

14. Performance acceptance criteria Section 32 1818, 1.7.F-G, 1.8.A.9-10 and 2.2.B.3; Section 32 1123, 2.1.B.

The turf section requires system infiltration greater than 16 inches/hour in testing but greater than 10 inches/hour in product requirements; the aggregate section references 14 inches/hour for the system including stone. Confirm the test method, assembly and governing threshold at each stage.

Also clarify initial padded-field G-max less than 120 versus the 80-165 warranty range and whether/when HIC must be retested during warranty.

15. Permits, inspection fees and delegated design Manual p.14, common scope J-M; p.70 General item 1; p.60 Sitework items 25-27.

Identify the permits, inspection/report requirements and fees specifically assigned to #32D, separate from Owner/sitework permits and the specified product/base testing. Confirm whether any signed/sealed engineering is required from #32D for turf/drainage/box work and identify the required deliverables. Confirm goal-post, net and concrete structural design remain with the assigned trades.

16. Turnover milestones and separate field acceptance Manual schedule pp.219-224; #32D multiple-mobilization requirement p.70.

The schedule lists fall sports beginning August 7, 2027 (TBD), first home game September 2, and stadium substantial completion September 8, with auxiliary substantial completion November 17.

Confirm mandatory playable-field turnover dates, field-specific base access/handoff dates, testing/training deadlines and whether early use initiates each field warranty separately. Identify required temporary protection and access maintained after each turnover.

DKorcek Text Box Per Specification 2.2E Maintenance Equipment shall be included in base bid.
