DISCLAIMER

The opinions and recommendations contained in this report are based on available drawings, on field investigations performed as a part of this project, and on analysis and calculations performed based on the information gathered. This report does not address any other portions of the structure other than the areas mentioned, nor does it provide any warranty, either expressed or implied, for any portion of the existing structure.

The recommendations presented in this report are limited by the extent and accuracy of information available to us during this evaluation. Conditions detrimental to the structure may exist which are not documented in the original drawings and were not visible or were not otherwise discovered during the field observation portion of this investigation.

This report is intended for planning purposes only and not for construction.

EXECUTIVE SUMMARY

Scope and Purpose

The purpose of this report is to evaluate the feasibility of structural rehabilitation methods to correct the structural deficiencies identified in previous reports (See UU Project #70240 for detailed reports). This study evaluates the ability of the seismic force resisting system to achieve a Risk Category IV performance level. Structural elements that do not achieve the performance levels associated with this Risk Category

IV structures are label as deficient.

This feasibility study evaluates two retrofit schemes for the East and West Building and three schemes for the MRI and Radiology additions. Each rehabilitation strategy has been developed to a conceptual level with plans, elevations, and details to inform construction cost estimates.

BACKGROUND

Reaveley Engineers was engaged by GSBS Architects to perform a seismic evaluation of Building 525 on the University of Utah campus. The results of that evaluation are documented in a report dated

February 3, 2020 (University of Utah Project Number 70240). The current effort is to perform a feasibility study to identify specific seismic retrofit options that address the deficiencies discovered in the prior evaluation. This report presents those conceptual retrofit options and provides an estimate of probable cost for each option considering only structural elements in the cost model.

Prior analysis found several structural elements do not meet the desired seismic performance objective.

Building deficiencies are listed in the table below. Structural elements not achieving the desired performance levels are deficient. The figure below shows the four areas of Building 525 that were included in the previous evaluation.

DESIGN METHODOLOGY AND PERFORMANCE CRITERIA

Conceptual seismic upgrade scenarios were designed per ASCE 41-17 Seismic Evaluation and Retrofit of

Existing Buildings following the Nonlinear Static Analysis procedure, also known as a pushover analysis.

Building 525 is a Risk Category IV building according to 2018 IBC and the performance objectives corresponding to the with Risk Category IV structures is shown in the following table.

Hazard Level Performance Level Sxs Sx1

BSE-1E Immediate Occupancy 0.403g 0.213g

BSE-2E Life Safety 1.019g 0.625g

Table 1 – Performance Objective used in the Design of Upgrade Scenarios

The purpose of this dual performance objective is to ensure the building will continue to support the community’s needs in the event of small to moderate earthquake and will also protect life safety during and after large earthquake.

Safety factors were used in the evaluation in accordance with the provisions of ASCE 41. Safety factors vary by element type and failure mechanism. Brittle failure mechanisms have higher safety factors than ductile yielding mechanisms. A knowledge factor of 1.0 has been used for this analysis.

PERFORMANCE CRITERIA DEFINITIONS

Immediate Occupancy

The structure remains safe to occupy and essentially retains its pre-earthquake strength and stiffness but may not function, negligible structural damage and minor non-structural damage, limited interruption to building operations, losses < 15% of value.

Life Safety

The structure has significant structural damage to components but retains a margin against the onset of partial or total collapse, some injuries may occur, extensive non-structural damage, building not safe to occupy until repaired, losses < 30% of value.

WEST AND EAST ANCILLARY BUILDING FINDINGS

Previous analysis of the West and East Ancillary buildings found some deficient exterior wall piers and concrete beams. Part of this evaluation included limited material testing and field verification. This was done to verify strengths of construction materials and to verify building modifications (new openings, infilled openings, etc.) that have occurred over the life of the building.

Two rehabilitation approaches have been evaluated to address deficient wall piers and coupling beams.

Deficient concrete members are proposed to be reinforced with either a new reinforced concrete jacket or a carbon fiber overlay. The retrofit aims to promote flexural hinging of concrete elements, in lieu of shear hinging in concrete elements.

Flexural hinging of concrete is a more ductile failure mechanism than shear hinging. The increase in ductility allows structural elements to deform and absorb more energy before breaking and losing strength. The retrofit measures below aim to achieve flexural hinging, improve ductility, and achieve overall building performance objectives.

CONCRETE JACKET RETROFIT

The concrete jacket retrofit involves placing a minimum of 6” of new reinforced concrete against deficient concrete walls piers and coupling beams. Prior to placing the new reinforced concrete, the existing concrete surface will have to be intetionally roughed and will have epoxy dowels installed along the length of the affected surface to promote good bond between the two layers of concrete.

This concrete can either be placed on the interior or exterior side of a deficient wall or beam. Work on the exterior of the building may be advantageous to the University to reduce distruptions to hospital functions. Work on the interior of the building will likely disrupt hospital operations in the area (dust barriers, temporary room shutdown etc.) Exterior application of concrete introduces a new aesthetic to the building such as intermittent thickened sections and troweled shotcrete finish that will be addressed from an architectural perspective in a future phase of the study.

The cost estimate in this report only considers placing concrete on the interior side of the wall. There will be some savings to apply the concrete to the exterior side of the wall due to less cost to address interior construction; however, those savings will be offset to a large degree by cost for scaffolding and costs to to enhance the exterior wall aesthetic.

CARBON FIBER RETROFIT

The Carbon fiber retrofit of deficient wall piers and coupling beams includes a significant amount of surface preparation prior to the application of carbon fiber strips around existing concrete walls and beams. Surface preparation is time extensive and must follow manufacturer recommendations to ensure proper bond between the carbon fiber and the concrete substrate.

Reaveley has been in contact with carbon fiber contractors to coordinate and assist in the retrofit design.

Typical retrofit schemes involve surface preparation, placing bonding agent, placing layers, (1) - (3) layers, of carbon fiber reinforcing over the length of the affected wall pier or beam in 2’-0” wide strips typically.

MRI AND RADIOLOGY ADDITION FINDINGS

Previous analysis found the following deficiencies of the MRI and Radiology buildings. See previous report for more detailed description of deficiencies.

1. Existing Moment Frame Panel Zones

a. Adequate to meet Life Safety Performance Objectives

b. Do not meet Immediate Occupancy Performance Objectives

2. Moment Frame Connections are Pre-Northridge type connections

a. Beams are not detailed to ensure the beam will yield prior to beam-column connection failure. Beams are susceptible to cracking prior to achieving design deformation.

3. Expansion Joint

a. The building separation joints between East Building, MRI Building, and Radiology

Building is smaller than the expected building movement in a major seismic event.

Pounding at the building interface can cause local damage and potential instability.

PROPOSED REHABILITATION STRATEGIES:

OPTION 1 - CONNECT BUILDINGS TO EAST ANCILLARY BUILDING

This proposed solution assumes the East Ancillary Building is strengthened to resist the added loads imparted by the interconnection of buildings. Rigidly interconnecting the MRI, Radiology, and East

Ancillary buildings together would require the following:

1. Connecting slab interfaces together with steel plates.

2. Interconnecting steel beams between buildings

3. Adding braced frames and/or concrete shearwalls in the MRI and Radiology Buildings

Pros:

1. Interconnection between buildings would reduce the seismic force demand placed on MRI and

Radiology buildings structural members. New forces delivered to the East Ancillary building would require additional strengthening of the East Ancillary building.

2. Existing moment frame connections are not required to be modified or strengthened.

Cons:

1. Increased strengthening of East Ancillary building would be required.

2. Interconnection of slabs could be disruptive along building interface, each side of existing joint.

Page | 8

OPTION 2 - WIDEN DRIFT JOINT

This proposed solution increases the joint dimension and modifies existing structural moment frames to achieve the desired performance objectives. This solution requires the following:

1. Increase joint between floor slabs by cutting back existing floor slab on the Radiology building at level 2. Not required at MRI Building.

2. Increase joint between roof of Radiology and MRI buildings by cutting back roof deck.

3. Repair column and beam connections moment frame connections

1. No major structural work at slab edges and building interfaces.

2. No additional strengthening of the East Ancillary building.

3. No addition of braced frames or concrete shearwalls

1. Work is required at all columns and may be intrusive and interrupt operations

2. Interconnection of slabs could be disruptive along building interface, each side of existing joint.

OPTION 3 - STRENGTHEN BUILDING WITH SHEAR WALLS/BUCKLING RESTRAINED BRACED FRAMES

This proposed method avoids modifications to existing beam-columns joints and avoids modifications to the joint between buildings by adding new structural elements to stiffen the existing building. This proposed solution requires the following:

1. Addition of new braced frames in the MRI

2. Addition of new concrete shear walls and/or Braced Frames in the Radiology building

3. Strengthening of existing foundations

1. No work along slab edges and building interfaces.

2. No modifications required at existing beam-column joints (Except at new frame locations)

3. No modification to East Ancillary building

4. Most of work is located at exterior perimeter of MRI and Radiology buildings

1. Addition of new braces or shear walls are intrusive and could interrupt operations

2. Foundation strengthening is required and could be intrusive and time extensive.

3. New shearwalls will likely interfere with current floor layouts

COST ESTIMATE

SCOPE

Construction Control Corporation developed the following estimates of probable cost. Details of the estimates are included in Appendix B.

SCOPE

Structural elements are included in the cost and impact to non-structural elements is not included. For instance, removal and replacement of ceilings, interior, and exterior finishes to install concrete walls is excluded, but the cost of the concrete, formwork and reinforcement is included.

SUMMARY

East and West Building

Retrofit Options Estimate of Probable Cost Non-Structural Impact

#1 – Concrete Jacketing $1,573,104 High (Medium if exterior installation)

#2 – Carbon Fiber $3,393,621 High

MRI and Radiology Buildings

Retrofit Options Estimate of Probable Cost Non-Structural Impact

#1 – Connect Buildings $760,289 Medium

#2 – Widen Drift Joint $704,455 Medium

#3 – Reinforce Buildings $2,037,665 High

Non-structural Impact

All seismic retrofit options will disrupt the use of the space where the work is being performed and will require the removal and replacement of non-structural elements. The amount of disruption depends on factors such as materials (placing concrete or installing steel elements), construction methods (welding, cutting, drilling, grinding), the size of the area required to perform the work, noise, and the potential for dust/debris. In each case, University policies will be followed for containment and cleanliness. The levels of non-structural impact are intended to provide general descriptions for comparison among the options.

Low Impact: Structural elements can be installed with isolated impact on non-structural systems (may require phasing to reduce impact). Room size areas are disrupted.

Medium Impact: Interior or exterior non-structural elements must be removed to install structural elements

(all work performed from either interior or exterior). Some structural elements require removal of exterior veneer. Larger areas are disrupted compared to “Low Impact”.

High Impact: Non-structural elements at interior and exterior are required to be removed to install structural elements. Larger areas are disrupted compared to “Medium Impact”.

SCALE:SF310 1/8" = 1'-0"

SCALE:SF310 1/8" = 1'-0"

A3 MRI ROOF FRAMING PLAN

OPTION 1:

INTERCONNECT EXISTING MRI BUILDING, RADIOLOGY BUILDING, AND EAST ANCILLARY BUILDINGS

TOGETHER. NEW STEEL BRACED FRAMES MAY BE REQUIRED.

PROS:

1. TAKE ADVANTACE OF EAST ANCILLARY BUILDING STRENGTHENING. ADDITIONAL STRENGTHENING OF EAST BUILDING WOULD BE REQUIRED, BUT WOULD ELIMINATE THE NEED TO MODIFY EXISTING BEAM-

COLUMN CONNECTIONS.

2. NO FOUNDATION STRENGTHENING

3. NEW STRUCTURAL BRACES WOULD BE LOCATED AT EXTERIOR PERIMETER OF THE BUILDING

CONS:

1. REQUIRE ADDITIONAL STRENGTHENING OF BLDG 525. FORCE INCREASE OF APPROXIMATELY 20%.

2. INTERCONNECTION OF FLOOR SLAB, ROOF DECK, AND COLLECTOR BEAMS IS POTENTIALLY DISRUPTIVE

ON EACH SIDE OF BUILDING JOINT.

DIMENSION AND PREVENT BUILDINGS FROM POUNDING IN MAJOR SEISMIC

EVENT.

EXISTING MOMENT FRAME CONNECTIONS IN MRI AND RADIOLOGY BUILDINGS

WOULD REQUIRE MODIFICATION TO MEET CURRENT CODE REQUIREMENTS.

PROS:

1. WORK IS LIMITED TO ROOF FRAMING ONLY. MODIFYING JOINT BETWEEN

BUILDINGS AND MOMENT FRAME BEAM TO COLUMN CONNECTIONS.

2. NO FLOOR OR FOUNDATION WORK

CONS:

1. EACH COLUMN REQUIRES MODIFICAITON WITH 26 BEAM TO COLUMN

CONNECTIONS. APPROXIMATELY 8' x 8' AREA AROUND COLUMNS WOULD

NEED TO BE PARTITIONED OFF TO PERFORM WORK.

2. SLAB AND ROOF DECK MODIFICATIONS COULD BE DISRUPTIVE.

3. MOMENT FRAME BRACING WILL NEED TO BE ADDED IN IDENTIFIED

LOCATIONS
