Project Profiles

The following Project Profiles will acquaint you with the size and scope of many of the typical projects in which we are engaged.

Client Objectives:

Sheraton-Kauai

  • Evaluate existing Concrete, Stucco and EIFS systems. Determine the extent of concrete spalling and stucco cracking, and design a solution to repair the damage and stop the deterioration of the structure.
  • Determine source of leakage at the guest room balconies.
  • Change, update and refresh the look of the exterior walls of the hotel
  • Determine a Probable Summary of Costs for Correction.
  • Complete the project while the Hotel is operating with minimal disruption to guests and hotel functions

Solution:

The Sheraton Kauai was originally built in1987. The property is separated into three (3) sections. The Oceanside, Beach Side, and across the road is the Garden Side. There are also the lobby, shops, restaurants, bars, pools, ballrooms and office structures on the property. Hurricane Iniki hit the Island of Kauai as a Category 4 hurricane on September 11, 1992 and destroyed the Beach Side of the resort. The new Beach Side hotel structures were rebuilt in 1995.

The Oceanside consists of two (2) buildings that are structural concrete. The larger building is a four (4) story structure and the smaller building is two (2) story. There are three buildings on the Beach Side and around the main pool area. These buildings are four (4) story conventional structural steel buildings with a combination of Stucco and EIFS veneers.

Arnold and Associates, Inc., Edward L. Arnold, RRC, RWC and William G. Hobgood, III, RRO, conducted an extensive review of the hotel facility focusing on the deterioration of the concrete structure of the Ocean Side Tower and the cracking of the stucco and EIFS on the Beach Side Tower. The balcony leak issues were also identified.

Once the repair areas were identified, and a new color scheme devised for the property, the project was put out to bid. The project was started in May of 2008 and completed and completed by the end of September.

Summary

  • Probable Cost: Approximately $1,279,000.00.
  • Project Name: Sheraton Kauai – Poipu Beach, Koloa, Kauai, Hawaii
  • Owner: Starwood Hotels & Resorts Worldwide, Inc.
  • General Manager: Angela Vento 808.742.1661
  • Director of Engineering: Jason Hasenberg

Client Objectives:

  • Roof replacement for multiple facilities of various square footage totaling approximately 200,000 square feet..
  • Investigate and specify the replacement of the existing roofing and gravel surfacing system.

Solution

Lubbock StateThe Texas Department of Health & Human Services Commission directly hired Arnold & Associates, Inc. to investigate and specify the replacement of the existing roofing and gravel surfacing system which was more than thirty-five (35) years old over twenty (20) buildings at the campus in Lubbock, Texas. The existing roofing, which was sloped in gable configuration, was installed directly to structural gypsum planks.

The gravel was removed form the asphaltic built up roofing on each building in preparation for installing a layer of gypsum recover board and 60 mil PVC membrane in a ribbed design (Sarnafil Decor System). The roof areas were designed with several different colors selected to enhance the identification of each building on the campus. The new roofing system is warranted by the manufacturer for twenty (20) years.

Arnold & Associates, Inc. has been working for the Texas Department of Health & Human Services Commission for approximately fifteen (15) years with work in major phases on twelve (12) campuses in the last three (3) years. Currently, Arnold & Associates, Inc. is working on other campuses including approximately 200,000 square feet of total roof area on multiple buildings in Abilene, Texas.

Summary

  • Roof Replacement: $2,200,000.00.
  • Owner:Texas Department of Health & Human Services Commission, Austin, TX.
  • Services Provided: Roofing and Waterproofing Consulting
  • Senior Project Consultant: Syd N. Singer, Arnold & Assoicates, Inc.

Hilton-Rose-Hall

Client Objectives:

  • Evaluate existing roof and facade per ASTM E 2128 “Standard Guide for Evaluating Water leakage of Building Walls” to determine extent of failure of roofing, balconies, fenestration and facade systems.
  • Determine source of leakage, condition, and document conditions with photographs and drawings.
  • Develop five-year plan to replace/renovate these systems to include short and long term goals.

Solution

Rose Hall Resort and Country Club consisted of two towers with a link in between where the main entrance, shops, administrative offices and dining is located. In addition, there are separate buildings consisting of the living quarters, golf pro- shop, and maintenance buildings. The hotel roof system was a sprayed polyurethane over a built up roof system on concrete decking. Living quarters are a wood frame with underlayment and asphalt shingles and the pro shop and maintenance is a wood frame with wood shingles.

Arnold & Associates, Inc. conducted an extensive review of the hotel roofing, facade, and fenestration systems developing a short and long term goals for repair and renovation of the hotel systems. A full review of the fenestration revealed that over 300 sliding doors in guest rooms framing, bearing and waterproofing had failed. The concrete balconies had significant spalling and rusting of the rebar; in some areas a dangerous situation due to the potential of pieces of concrete falling to the ground. The hotel roof system had water in-between the sprayed polyurethane roof and the built-up system acting like a waterbed resulting in infiltration of water into the hotel. The gulf pro-shop and maintenance wood shake roofs had major deterioration of the shingles resulting in infiltration of water into the facility.

Arnold & Associates immediate task was to stop the leaks so long term solutions could be developed. The design criteria included increasing the R-value of the roofing from the existing 2 to well over R-15 and wind loads were established at over 150 miles per hour.

Specifications for repair of the leak areas were completed and work was started for these repairs. During this process Hurricane Ivan had a direct impact on Rose Hall Resort blowing out many of the sliding glass doors. Emergency replacement specifications were developed for the replacement of over 40 sliding glass doors. To date all roofs have been replaced with modified bituminous roof systems and wood shakes. All sliding glass windows have been replaced, balconies rebuilt, store front windows replaced and facade system recoated.

Summary

  • Roof Replacement: $2,800,000.00.
  • Sliding Glass Door Replacement: $1.8M
  • Emergency Repairs: $229,000.00
  • Concrete Repairs: $390,000.00
  • Store Front Replacement: $1.2M

Client’s Objectives:

  • Evaluate existing curtainwall system to determine extent of failure of existing gaskets and frame design.
  • Determine source of leakage at intersection of curtainwall system and roof areas where water is leaking into hotel.
  • Determine a Probable Summary of Costs for Correction.

Solution:

The W New Orleans is a recently converted and renovated 24 story hotel property located in downtown New Orleans adjacent to Harrah’s Casino. The exterior curtainwall system is glazed with reflective glass in dark bronze anodized frames with spandrel glass panels at each floor level.

Arnold & Associates, Inc. conducted an extensive review of the hotel facility focusing on those leak issues which have become evident after the major hotel conversion and addition in 1999-2000, approximately (3) years ago.

Arnold and Associates, Inc. Consultant Michael L. Cogburn, AIA, CSI completed the review from a two man basket on two separate drops on separate sides of the building. Additionally, a full examination of the sill condition of the curtainwall system above the roof areas was completed.

Aged gaskets were brittle causing leakage through the window system. Inappropriate seaman installation which dams up the designed weeping systems of the curtainwall system above fourth floor roof areas is recommended to be corrected immediately to allow use of meeting rooms and guest rooms during rain conditions. Additional testing requiring a full removal of the lower sections of the curtainwall system (sill, subsoil, glass, etc.) was suggested and recommended to fully understand the conditions which exist that allow water to enter the inside of the guest room spaces adjacent to this wall condition at the fourth floor

Solution:

The Don Cesar Beach Resort & Spa was originally built in 1927 and has had a long history of prominence on the beach on the west coast of Florida. Its unusual history includes the buildings use as a hospital, convalescence center in WWII, a VA office building, and was once even considered for demolition.

Beginning in 2004, Arnold and Associates, Inc., Architect/Senior Consultant Michael Cogburn, AIA, CSI, conducted an extensive review of the hotel facility focusing on the deterioration of the structure and the cracking of the stucco. The original budget was established at approximately $1.5 million.

Once the Scope of Work was fully defined, the project was issued for bidding. The project was awarded to Valcourt Building Services started in October of 2005 and completed by Christmas, 2006. The Project was highly successful and substantially under budget.

Client’s Objectives:

  • Stop leaks through windows and exterior masonry wall system.
  • Restore exterior masonry wall construction to a water resistant assembly.
  • Improve aesthetics through extensive cleaning of masonry and coatings.

Solution:

Eight (8) story brick veneer hospital required extensive curtainwall leak repair, masonry waterproofing, and cast stone restoration including installation of new sealants, end dams, and penetrating masonry sealer.

Hospital administration was unsure of how to proceed and reluctant to enter into an agreement with a consultant or architectural firm that was unable to be trusted to solve the water infiltration issues on the facility. A number of “bad experiences” prompted a cautious approach to hiring a waterproofing consultant. Upon research into Arnold & Associates, Inc. references and multiple discussion, Arnold & Associates, Inc. was selected to proceed with first phase of the evaluation and testing services.

After initial evaluations and extensive testing of the exterior masonry wall systems, Arnold & Associates, Inc. successfully identified the sources of water infiltration in several areas of the facility.

The existing aluminum curtainwall system was experiencing significant aging in the gasket system which resulted in wind blown rain forcing itself through the seals and into the interior spaces during thunderstorms. In addition, the perimeter sealants around and at end conditions were also aged, brittle, and cracking contributed to great quantities of water infiltration around the system.

all project profiles 2016_Page_12_Image_0001

The original design and construction did not provide for needed through wall flashings and end dams to prevent water from migrating into interior spaces. Consequently, hospital offices, patient rooms, and ancillary spaces continued to leak.

In one area, an executive conference room, leaks were continuing for a period of eight (8) years without resolution. Arnold & Associates successfully identified the source of water infiltration and designed correction.

Project was continued and specifications were written, details drawn, and experience waterproofing contractors contacted to bid the work.

Project was successfully completed, on time, and on budget with excellent results…..no leaks!

Client’s Objectives:

  • Roofing and Waterproofing System Selection.
  • Design Specifications and Detailing for the Development.
  • On-site Field Observation.

Solution:

Flushing Town Centre which later became Sky View Parc is a significant multi-use development in Flushing, NY directly under the flight path of La Guardia Airport. The development encompasses approximately 14 acres of ground area which also reflects the size of the roofing / waterproofing extent. The development has large retail tenants below the podium level and a landscaped activity level above the large retail area and an amenity deck on the multilevel parking structure. Initial condominium and apartment units include three multi-level towers including approximately 448 units. Future towers are designed to accommodate another 619 units

all project profiles 2016_Page_05_Image_0001

Arnold & Associates, Inc. was selected to provide the roofing and waterproofing system selection and design specifications and detailing for the development.

all project profiles 2016_Page_05_Image_0002

Working with the design architects, landscape architects, mechanical/electrical/plumbing engineers, and owner/developer representatives, Arnold & Associates, Inc. combined hours of research and analysis of systems into a formal presentation and recommendation on system selection. Once roofing and waterproofing systems were selected, Arnold & Associates, Inc. Senior Consultants integrated the system selections into comprehensive specifications for the project. Working closely with architects with Perkins Eastman, Inc.

all project profiles 2016_Page_05_Image_0003

Arnold & Associates, Inc. specified all below grade waterproofing systems which were installed to prevent water migration and contamination into the lower portions of the development. Below grade hydrostatic pressures were reviewed and materials and thicknesses were determined. All below grade waterproofing systems were installed on the positive side of the structural concrete systems. Products selected were carefully installed at lower structural slabs and piling caps as well as vertical wall conditions below grade. Contractor installation was monitored by Arnold & Associates, Inc. Senior Consultants and manufacturer’s technical representatives to ensure a successful long term solution.

all project profiles 2016_Page_06_Image_0001

Roofing systems were also chosen and specified by Arnold & Associates, Inc. in collaboration with the Architects of Record, Perkins Eastman of New York. Extensive review of conditions above the  large retail space below the podium level created  challenges with requirements restricting the number of roof penetrations and drains. The owner/developer envisioned a highly landscaped podium level, and landscape screened areas and grass areas were developed to compliment the overall pedestrian experience and design. Waterproofing systems were selected instead of roofing systems due to the extend of landscaping, hardscape, and pedestrian walkways required by the designers. Reflective roofing systems at the three towers required extensive coordination and selection in order to provide the most effective solution to incorporate with mechanical systems and roof penetrations. Arnold & Associates, Inc. also advised and specified deck coating systems and other specific materials and systems including sheet metal flashings.

Project Cost for Roofing, Masonry Repair, and Waterproofing

Total Project Costs = Approximately $450,000

all project profiles 2016_Page_17_Image_0003

Client’s Objectives:

  • Provide replacement of existing sealants at the perimeter of windows and control joints
  • Provide masonry repair and tuck pointing procedures
  • Provide cleaning of existing masonry
  • Provide specialized cleaning of anodized aluminum window frames to remove heavy oxidation and staining
  • Provide specialized cleaning of window glass to remove streaking which would not clean with typical window cleaning         techniques

Solution:

Upon examination of the building, it was noted that to remove existing sealants properly would require excessive grinding of the masonry. The potential of dust entering the hospital rooms due to the grinding was too great. We, therefore, designed the new sealant joints at the perimeter of windows to be installed using extruded silicone spanning over the existing sealant which was allowed to remain in place.

all project profiles 2016_Page_20_Image_0001
all project profiles 2016_Page_20_Image_0002

Both the glass and the metal window frames were discolored and stained from lime deposits bleeding out of the precast spandrel panels and from oxidation. The lime deposits were streaked on to the glass and would no longer clean. We recommended the use of a specialized cleaning process for the metal frames utilizing volcanic pumice as an abrasive cleaning agent.

For the glass, we recommended the use of a specialized cleaning process using cerium oxide as a polishing agent to clean the glass.

The total project included the use of silicone sealants and extruded silicone for waterproof joints. The masonry was tuck-pointed, received limited areas of masonry replacement, was cleaned and treated with a clear water-repellant.  The windows were wet-glazed with silicone sealant to address the deteriorating neoprene gaskets. The exterior aluminum frames at windows and louvers were cleaned with the specialized process. The exterior glass was cleaned and the project was expanded to also include cleaning of the interior glass panes.

The project was originally budgeted at $416,283.00. Butch’s Waterproofing Company of Houston, Texas, the primary contractor, completed the project within eight months at a final project cost of $373,400.00.

Client’s Objectives:

  • Provide new roofing to replace existing coal-tar roofing which was more than thirty-five years old
  • Provide new roofing for as many buildings as possible. The project listed twenty-three buildings to receive new roofing, but only fourteen were included in the original budgeting prepared by the client prior to the start of the project.

Solution:

Upon investigation of existing conditions, we found the building to have coal-tar bitumen roofing with gravel surfacing. The roofing had been mopped directly to a perlite-based lightweight fill material placed over structural concrete planks. The existing roofs had no slope for drainage.

The existing conditions allowed gravel to be vacuumed and the existing roofing to remain as a temporary roof. Vermiculite-based lightweight insulating concrete was poured over the existing roofing to provide both thermal insulation and sloped to drainage. A two-ply modified bitumen roofing system with a twenty-year manufacturer’s warranty was placed over the lightweight insulating concrete.

To address the differential between the number of roofs which needed new roofing vs. the budgeting restrictions, we included the budgeted buildings as the base bid and allowed each additional building to be bid as an alternate bid item. Since we had been able to design a roofing system which did not require tear-off of existing roofing, the budgeted funds extended further than the fourteen buildings included in the budget.

all project profiles 2016_Page_19_Image_0001

The original bid allowed roofing of all the budgeted buildings plus a classroom building and the campus kitchen. Before the contract could be awarded, fire damaged the roof of the main administration building. Since roof replacement of the administration building had been included in the bidding, the required structural repair and roof replacement of this building was also included in the contract.

Near the end of the project, high winds blew a portion of the roof off of the Central Boiler Building. Since this building had also been included in the bidding, the new roof for this building was added to the contract and roof replacement began within five days of the wind damage.

The Project was originally budgeted to reroof fourteen buildings with $693,000.00. Sixteen building roofs were awarded within the original budget and at the completion of the project, Seyforth Roofing Company had installed the new roofing system on eighteen buildings within seven months at a final cost of $814,353.00.

Westin Peachtree Plaza – Atlanta, Georgia

Client’s Objectives:

  • Tower Glass Replacement
  • Scenic Elevator Reglaze
  • Sundial Restaurant Reglaze
  • Skylight Glass Replacement

Solution:

On March 14, 2008 a tornado with wind speeds over 200 mph ripped through Atlanta. The Westin Peachtree Hotel sustained extensive glass damage. 540 glazing units were broken and over 70% of the scenic elevator glass were damaged. 100% of the skylight glass was impacted and 81 rooms were out of service long term. Westin Peachtree Hotel is 723 feet tall with 73 floors and 320 rooms. It is the second tallest hotel in the Western Hemisphere. For this project 6,350 panes of glass were replaced and 800 skylight units.

Arnold & Associates, Inc. conducted an extensive review of the hotel and also developed a comprehensive permit and bid package for correction.

Project challenges included safety of guests, general public and construction personnel, as well as logistics of loading/unloading, materials and labor transportation. The sequencing of construction was developed to minimize noise/disruption to hotel operations. Five (5) floors were taken out of service at a time as work progressed from top to bottom. The 15 month schedule was completed on time with minimal hotel disruption.

Some of construction challenges were in working with Skanska Inc and Harmon Inc. making sure the project and all involved followed strict safety guidelines. 100% tie-off for glazers and netting had to be at each window location. Protective film on had to be installed on each glazing unit before removal. Swing stages were staged around the entire perimeter and tools had to be tethered to each worker. Pedestrians were protected with low level netting and pedestrian walkways at street level.

Construction Cost: $22,500,000.00

Southwestern Medical Center at Dallas – Dallas, Texas

Client’s Objectives:

Evaluate and direct the roofing projects on multiple buildings on the University campus.

Scarification of the existing SPF roofing system.

Solution:

Over the last ten (10) years, The University of Texas Southwestern Medical Center at Dallas has enlisted the professional services of Arnold & Associates, Inc. to evaluate and direct the roofing projects on multiple buildings on the University campus. Demolition of the existing SPF Roofing system was considered, but was not taken due to the significant savings of reconditioning the existing SPF roofing systems. New silicone coatings used for all roof projects provide long term durability and protection from UV light degradation.

Projects consisted of scarification of the existing SPF roofing system and installing additional thickness of polyurethane foam and silicone coating system. Systems installed were completed during regular business hours and weekends with strict coordination with Engineering Staff due to highly sensitive building occupants.

Arnold & Associates, Inc. has provided waterproofing services as well as roofing design/documentation services for multiple other projects on campus through the Physical Plant.

Final Cost = Approximately $1.5M

Project Name:

The University of Texas Southwestern Medical

Center at Dallas

Consultant: Michael L. Cogburn, AIA, CSI

Client’s Objectives:

  • Evaluate existing Concrete Decks, Masonry, Siding, Balcony Hand Rails, and Metal Roofing systems. Determine the extent of concrete spalling and facade deterioration, and design a solution to repair the damage and stop the deterioration of the structure. Determine source of leakage into the below grade parking garage, and design the waterproofing solutions, and coordinate the sub-consultants responsible for designing the snow-melt system at the front entrance driveway.
  • Change, update and refresh the look of the exterior walls of the hotel. Determine a Probable Summary of Costs for Correction. Complete the project while the Hotel is shut down for the spring and fall seasons.

Solution:

The Sheraton Steamboat was originally built in1980. The resort is located at the base of the Gondola that services the ski mountain. The original wood balcony handrails were is poor condition and gave the hotel a dated appearance. The front entry driveway is located over the parking garage. There were two main issues at play for this portion of the project. First there were numerous leaks into the parking garage, and it basically rained in the garage year around. The other issue was the shoveling and melting of snow around the entrance walkway and to the shops and ancillary buildings and the excessive amount of labor that it took to keep the area cleaned for the guests to safely pass.

Arnold and Associates, Inc., William G. Hobgood, III, RRO, conducted an extensive review of the hotel facility focusing on the deterioration of the concrete balcony decks, masonry, balcony handrails and the front entrance drive and parking garage of the Resort. Arnold & Associates, coordinated with the Owner’s Architect and the snow-melt system design team to produce the contract documents.

A new color scheme was devised for the property, as well as a new balcony handrail design, the project was put out to bid. The project was started in August of 2008 and completed in several phases by the end of May of 2010.
