About this file
This is a Scope of Work document for UNC Charlotte's Stormwater Master Plan Implementation Phase 1 project in North Carolina. The project encompasses comprehensive stormwater infrastructure improvements across the campus, including the design and installation of best management practices (BMPs), green infrastructure features, and associated site improvements to manage stormwater runoff and comply with regulatory requirements. The scope includes site assessments, engineering design, permitting support, construction administration, and implementation of stormwater control measures such as bioretention areas, permeable pavements, retention ponds, and related drainage improvements. The project is organized in phases, with Phase 1 focusing on priority improvements identified in the stormwater master plan. Specific deliverables, timelines, and performance standards are established to guide contractor execution and project oversight throughout the implementation period.
The project funding and budget parameters, pricing structure, and any cost allocation methods are established through the contract terms. The document outlines technical specifications, performance requirements, and quality standards that contractors must meet during implementation. Additional details regarding site access, environmental compliance, coordination with campus operations, and any constraints related to the active university environment are addressed to ensure successful project delivery while maintaining campus functionality.

Questions
The following questions have been received during the open question period for the project. These answers are direct guidance to the bidders and will ultimately be reflected in the conformed set of contract documents upon which the project contract will be based. Our response comments are bold.
1. Are BW elevation points on C3.00-A bottom of wall at finished grade or top of footing? If bottom of wall at grade, please provide top of footing elevations since there are no depths specified in wall details.
Answer. The BW elevations as provided on C3.00-A are representative of finished grade. Top of footing elevations are not provided. It is the contractor’s responsibility to coordinate top of footing elevation with finish grade, 12” min. frost depth, and footing thickness.
2. Please provide drainage details for landscape and hardscape inlets including drain pipe size and layout (particularly landscape inlets)
Answer. The hardscape / landscape service line layout, grate sizes, rim elevations, and invert in / out elevations are provided on C3.00-A. Sheet C3.00-A was updated to call out pipe size (4” min, typical). The hardscape and landscape inlet details are provided on L4.02-A.
3. Are there more areas of W-05 turndown curb wall than highlighted on C2.00-A? Schedule on C2.02-A has 257 LF but only 156 LF showing on C2.00-A.
Answer. There are no additional areas of W-05 turndown curb. 156 LF is the total length. The schedule on C2.02-A has been updated to reflect what is shown on C2.00-A.
4. Are there more areas of ST-05 concrete steps than highlighted on C2.00-A? Schedule on C2.02-A has 133 LF but only 87 showing on C2.00-A.
Answer. There are no additional areas of ST-05 concrete steps. 87 LF is the total length. The schedule on C2.02-A has been updated to reflect what is shown on C2.00-A
5. Demo plan shows portion of asphalt and brick crosswalk of Craver Road removed, but site plan shows no road repairs to paving or crosswalk. Are these repairs being handled by UNCC or in this project scope? If in project scope, please provide asphalt and brick paving profiles.
Answer. The road renovation is included in the project scope and additional site plan information has been provided on Sheet C2.00-A. Associated details have been provided on the new sheet C8.00-A. There is no demolition to existing crosswalks. The existing crosswalk at the shuttle stop will remain undisturbed, with the road renovations tying into the existing grade at the crosswalk.
6. Please confirm all curbing and flush bands with sizes, widths, and details along Craver Road on C2.00-A Answer. Information has been provided on sheet C2.00-A.
7. What is the contract time for this project? Article 23 of the specifications states "xx consecutive calendar days". Form of contract days is also blank.
Answer. Construction duration is 300 calendar days. This information can be found in the updated Supplemental General Conditions, Article 23 and the Form of Construction Contract included in this Addendum. Please note too, that the University has established a black-out period for construction from June 25 – July 5, 2027 should construction extend into this timeframe.
8. E051 has a note to "coordinate exact routing for feeder with UNCC engineering before rough-in". Please confirm a rough idea of routing needs so the EC can estimate the cost to carry for this project scope in order to tie into the building's interior electrical room.
Answer. I’m still waiting for a response from our electrical engineer. Will send out a separate response for this specific question Monday morning, August 3rd.
9. Please advise if steel fabricator must have AISC certification, or if qualifications and previous work will be acceptable.
Answer. We will consider waiving the AISC fabricator certification provided appropriate qualifications are acceptable.
10. C9.04-A shows rim of JB-5 at 673.64 and invert out at 671.97. That's a height of 1.67' and will not accommodate 24" RCP. Was this the old invert to abandon in place pipe?
Answer. Elevation and note updated for JB-5. Junction box will be installed by others from project working in parallel and will just need to have new pipe installed on the west side for our project.
11. Will JB-5 need to be cored to accept existing storm drain from across Craver Road? And if so, what is the size and type of this pipe?
Answer. Please see updated note, JB-5 installed by others and all our project will incorporate is what is shown on the plans.
12. C9.04-A has length of pipe going to Forebay 1 as 24" RCP, but C9.01-A has this run as 15" RCP. Please clarify.
Answer. Pipe will be 24” RCP, C9.01-A has been updated.
13. C9.01-A has standpipe in forebays as 3" with dome grate. Please confirm 3" dimension is accurate and what kind of dome grate you are looking for on a 3" pipe.
Answer. 3” dimension is correct, dome grate similar to one like this:
