About this file
This is a comprehensive set of construction documents for a tunnel repair and replacement project for the Iowa Department of Administrative Services (DAS) located at the Clarinda Correctional Facility in Clarinda, Iowa. The project involves repairing and replacing tunnel infrastructure in the main building's southwest wing, specifically focusing on two tunnel sections with project number 9444.00 and bid number RFP944400-01. The documents, dated October 10, 2025, include detailed structural, civil, mechanical, electrical, and plumbing plans for demolition and reconstruction of tunnel systems spanning approximately 600 linear feet across two tunnel segments.
The project involves complete removal and replacement of tunnel components, including concrete lid, pavement, piping systems (chilled water, steam, hot water), electrical conduits, and lighting. Key elements include installing new pipe supports, replacing steam traps and pressure reducing stations, adding sump pumps, and implementing new electrical infrastructure. The construction documents specify Schedule 80 CPVC piping, structural steel supports, and careful coordination between mechanical, electrical, plumbing, and structural contractors. The work requires precise removal of existing systems, protection of adjacent infrastructure, and installation of new systems with minimal disruption to the facility's operations. Structural repairs, concrete restoration, and utility system replacements are comprehensively detailed across multiple plan sheets and technical specifications.

SITE PLAN NOTES
1. TUNNEL IMPROVEMENTS AS FOLLOWS: SEE STRUCTURAL PLANS FOR
DETAILS.
A. REPLACE TUNNEL LID AND INSTALL NEW ACCESS HATCH.
2. PAVEMENT IMPROVEMENTS PROVIDE THE FOLLOWING:
A. 6" PCC PAVEMENT, REFER TO SUDAS STANDARD SPECIFICATIONS
SECTION 7010.
B. 4 TO 6" PCC DRIVE AREA PAVEMENT OVER THE TUNNEL. PROTECT
THE TUNNEL LID.
3. GRADES SHOWN REPRESENT FINISHED GRADE/TOP OF SLAB
ELEVATIONS UNLESS OTHERWISE NOTED. ALL EXISTING AREA INLETS
SHALL BE ADJUSTED TO GRADE.
4. PROVIDE POSITIVE DRAINAGE AWAY FROM BUILDINGS AND TUNNEL
DIRECTED TOWARD THE EXISTING STORM SEWER INLETS.
5. CONTRACTOR IS RESPONSIBLE FOR ANY EXCESS OR NEEDED SOIL FOR
THE SMALL GRADING CHANGES MADE OVER THE SITE. THIS ITEM IS
SUBSIDIARY TO THE 6" PCC PAVING ITEM.
6. SEED ALL DISTURBED AREAS NOT INDICATED FOR PCC INSTALLATION
WITH SUDAS TYPE 1 SEED MIX, REFER TO SUDAS STANDARD
SPECIFICATIONS SECTION 9010. FOLLOW PROPER SOIL PREP INCLUDED
WITHIN THE SPEC.
7. ACCESS TO THE FUELING AREA NEEDS TO BE MAINTAINED AND/OR
COORDINATED WITH CONSTRUCTION PHASING TO ENSURE FUEL IS
AVAILABLE WHEN NEEDED. IF A LONGER HOSE CAN BE INSTALLED
THEN FUELING MAY BE ABLE TO BE COMPLETED FROM THE GRAVEL
AREA.
8. ACCESS TO THE DOCK DELIVERY NEEDS TO BE MAINTAINED AS MUCH
AS POSSIBLE. ANY SHUTDOWNS NEED TO BE COORDINATED WITH CCF.
9. WITHIN THE DRIVE AREA, WHERE NEW PAVEMENT WILL BE INSTALLED
OVER THE UNDISTURBED TUNNEL TOP, A CONSTRUCTION JOINT SHALL
BE USED SO THAT CRACKING ALONG THE TUNNEL LID DOES NOT
FOLLOW THROUGH THE NEW DRIVE AREA PAVEMENT. THE PCC OVER
THE TUNNEL & THE DRIVE AREA PAVEMENT SHALL BE SEPARATE
POURS. THE TUNNEL IS MEANT TO BE THE HIGH POINT OF THE AREA SO
THAT WATER WILL SHED AWAY FROM THE TUNNEL TO THE AREA INLETS.
THE JOINTING LAYOUT SHALL FOLLOW SUDAS CHAPTER 5 SECTION 5G
(PCC PAVEMENT JOINTS), AND SECTION 7010.101 (PV-101). THE
JOINTING PLAN SHALL BE SUBMITTED TO THE ENGINEER AS A SHOP
DRAWING, AT LEAST 48 HOURS PRIOR TO PAVING. THE THICKNESS OF
THE PCC OVER THE TUNNEL MAY VARY SLIGHTLY BASED ON MAKING
THE TUNNEL THE HIGH POINT. ENGINEER SHALL VISIT THE SITE AFTER
FORMS ARE SET AND PRIOR TO POURING CONCRETE.
10. CCF WILL ADJUST DOWNSPOUTS ACCORDINGLY AFTER PAVING.
11. CONTRACTOR TO MATCH EXISTING PAVEMENT MARKINGS.
12. CONTRACTOR TO REMOVE VEGETATION FROM THIS CORNER &
REPLACE WITH 6" PCC OVER 12" PREPARED SUBGRADE. GRADE TO
ENSURE POSITIVE DRAINAGE.
