Executive Summary for the

Reconstruction of Huguelet Drive Steam Piping, Vaults and Tunnel (Design Only) for the UNIVERSITY OF KENTUCKY Main Campus PROJECT NO. 2568.0 PROJECT SCOPE: $90,000 A. INTRODUCTION

This program presents in summary, the requirements for the preparation of design, construction documents and estimates for reconstruction/modification of the steam piping, vaults and tunnel at the intersection of Huguelet Drive and Rose Street in Lexington Kentucky on the campus of the University of Kentucky. The program is prepared as a basis for understanding and agreement within the University and as a definitive statement to the Consultant engaged in the design of the Reconstruction of Huguelet Drive Steam Piping, Vaults and Tunnel (Design Only) project. The University reserves the right to negotiate an extension of the contact to include construction administration after the design is complete and the project scope is established.




B. PROJECT DESCRIPTION

In late June of 2021 structural engineers of Brown and Kubican completed an inspection of the steam vaults and tunnel at the request of University of Kentucky Physical Plant Division. A copy of the report resulting from this inspection is provided with this advertisement. The report describes water damage to both the concrete and steel members of the existing tunnel connecting two vaults which are deteriorated beyond the point of repair.

The purpose of this project is a complete evaluation of various possibilities for and the completion

of the reconstruction and/or replacement of the steam piping and vaults to include the protection or replacement of the existing steam piping and valving within. When a recommendation for the best and final solution for the reconstruction/replacement of the piping, vaults and tunnel has been detailed, the project will move forward immediately to design. The condition of the existing vaults and tunnel must be addressed at the earliest possible date.

The design will consist of preparation of Phase 1, 2 (if required), and 3 documents in accordance

with University standards and procedures.

Structural Assessment of Existing Utility Tunnel Page 1 of 5

June 30, 2021 Mr. Graham Gray Utilites System Manager University of Kentucky Capital Project Management Division 211 Peterson Service Building Lexington, KY 40506 RE: Structural Assessment of Utility Tunnel at Rose/Huguelet (HPS 46 & 47)

University of Kentucky Lexington, Kentucky B+K Project No. 21195 Mr. Gray: As requested, we visited the site of the referenced structure on June 25, 2021. The purpose of our visit was to observe the reported deterioration of the existing utility tunnel at the intersection of Rose St and Huguelet Dr, determine the cause of the deterioration, assess the extent of the deterioration, and make recommendations. Our investigation was visual in nature and was limited to manholes HPS 46 & 47 and the tunnel between them. No other utility tunnel structure was investigated. Construction materials were not sampled or tested, and no calculations were performed. Photographs were taken to document existing conditions, some of which are included herein. Structural Description The tunnel was constructed circa 1998-99. The original construction drawings you provided for reference were dated November 9, 1998. The drawings indicated that the existing tunnel was constructed with 6 ft wide x 6 ft tall prefabricated concrete culvert segments that were delegated designed by the precast concrete supplier. Water-tight sealant and grout were required to seal the joints between the segments per the construction documents. Manholes HPS 46 & 47 at both ends of the tunnel were also made of prefabricated concrete units. According to the on-site conversation with your staff, no waterproofing was applied to the exterior surfaces of the tunnel or manholes during the construction. The tunnel was repaired and shored around 2017. The shoring/repair drawings you provided were prepared by BFMJ Consulting Structural Engineers. One set was the markups on the original drawings dated November 1, 2016, and the other set was the shoring drawings and photos dated April 2017. Based on the existing drawings, a galvanized steel frame should be installed at each joint between the existing concrete segments to support the tunnel ceiling slab. Each shoring frame consisted of (3) C12x31 channels, and they were connected to the ceiling slab and tunnel walls. The thickness of the ceiling slab and walls was likely to be 6 inches.

Observations During our visit, we made the following observations:

1. Existing Manhole HPS 46: We observed spalling concrete on the surface of both lower and upper sections of the vault. Reinforcing steel has corroded due to water (see photo 001). Continuous horizontal cracks were observed in the mid-lower part of the wall. We believe that it was caused by tension failure of the concrete from the applied lateral earth load (see photo 002).

2. Tunnel Walls:

Existing concrete tunnel walls appear to be in good condition. See photo 003.

3. Existing Tunnel Ceiling Slabs: We observed a double-layer ½"± thick steel form deck below the concrete ceiling slab. It was not shown on either the original drawings or the repair drawings. The direction of the steel deck is parallel to the mechanical pipes and perpendicular to the shoring frames. We believe that the existing steel deck was added to support the deteriorated concrete ceiling slab during the repair in 2017. We observed that the deck is supported on the horizontal steel channel, and all the gaps at deck flutes were grouted solid (see photo 005). The existing deck is severely corroded due to water along the whole tunnel (see photo 004) except for a small portion in the middle of the tunnel (see photo 006). Most parts of the existing concrete ceiling slab were concealed by the corroded steel deck, but the exposed part and the end view of the slab both showed severe water damage, such as spalling concrete and corroded reinforcing steel (see photos 007 & 004).

Corroded deck is supported on steel channel with gaps at deck flutes being grouted.


Only a small portion of the existing deck appears to be less damaged by water.

The reinforcing steel of the ceiling slab has severely corroded.


4. Existing Manhole HPS 47: We observed spalling concrete on the bottom surface of the soffit slab. Most of the existing concrete below the slab rebar has fallen, and the slab rebar is exposed and severely corroded. A wide crack was observed right above the soffit slab, and we believe it was due to concrete failure from the lateral earth load (see photo 008). Corroded reinforcing steel was observed at the wall surface (see photo 009).



5. Existing Steel Shoring Structure:

Based on the existing drawings, all the steel shoring frame members and connectors should be hot-dipped galvanized. We found the vertical channels connected to the existing walls appear to be in better condition than the horizontal channels connected to the ceiling slabs or walls.

The channels supporting the steel form deck have corroded on their top and side surfaces (see photo 010). Many adhesive anchors mounted to the existing ceiling slab have corroded and fallen (see photo 011).

The adhesive adhesive anchors connecting the channel to the manhole wall have corroded (see photo 012). A reinforcing steel plate (supposed to be a tube beam per the repair drawings) with its anchors at the end of the tunnel has severely corroded (see photo 013).

Recommendations It appears that the water damage in both concrete components and steel shoring members of the existing tunnel has developed since the repair in 2017, and the situation will only become worse. It is our opinion that the existing concrete tunnel has deteriorated beyond the point of repair, and it should be demolished, backfilled, or reconstructed as soon as possible. We strongly suggest staying away from the existing tunnel for safety concerns. The existing manholes HPS 46 & 47 were made of precast concrete units. We observed spalling concrete, exposed reinforcing steel, and wide cracks in both vaults, which indicated local structural failures. We recommend that both of them be demolished and reconstructed. We would be glad to be involved in any future project related to this assessment if possible. We can prepare construction documents and provide construction administration services for the potential project upon request. If you have any questions or if we can be of any further assistance, please call. Best regards,
