PROJECT DESCRIPTION

Please provide a 150-200 word description of the

project being nominated. If selected to receiveAfter running continuously for 111 years, the historic Olmsted Hydroelectric Power Plant located at the mouth of Provo Canyon went o�ine for the last time in the fall of 2015. In September of 2016, Ames Construction mobilized

an award, this description will be used during

the awards ceremony.to the site to replace this historic facility with a new state-of-the-art hydroelectric power plant. The project work included: lining an existing 12-foot rock tunnel with 84-inch steel pipe, encasing the annular space between this pipe and the rock tunnel with low-density cellular concrete, constructing a new cli� spill structure, surge tank, powerhouse building, and 84-inch buried penstock (on 1.75:1 slope), hydroelectric equipment installation and a new power transmission line. The new system, considered the �agship facility for Central Utah Water Conservancy District, will achieve a broader mission of power generation and regional water conservation.

STRUCTURE QUESTIONNAIRE

Please be as detailed and descriptive as possible, highlighting what makes this project special or unique. This information is the most important for our jury panel to determine the project's worthiness of recognition.

OVERVIEW

1. Give an overview of the project. What unique

or unusual concrete features are incorporated in

this project? List both structural and architectural

concrete elements and/or products.

The new powerhouse facility was designed to �t in aesthetically with the registered historic facilities that remain intact immediately adjacent to the new construction. The new building was constructed of multi-level subsurface and above ground concrete waterways, sumps, tall cast-in-place concrete walls and suspended decks with an aesthetic brick veneer, stone-coated metal shingles, and rooftop dormers that allow the facility to blend in with the historic facilities, but also has the appeal of a shiny new, technologically advanced, modern power plant with the capability of being operated unmanned over 95% of the time. The new powerhouse facility was excavated adjacent to the Provo River to a depth of 45 feet with massive amounts of groundwater present. An extensive dewatering system was implemented to control this immense volume of groundwater, which ran continuously for over a year to keep the excavation dry for concrete placements. The project logged more than 250,000 manhours (173,000 Ames and 77,000 subcontractors), and was completed with no recordable or lost time injuries!

DESIGN

2. What architectural design successes were

realized? This could include specific finishes,

shapes, project properties or functions that are

benefited by the use of concrete.

A combination of modular formwork (DOKA) and conventional lumber formwork was used to construct over 7,000 cubic yards of concrete through the harsh Utah winters and hot summers.

3. What engineering design accomplishments

were achieved? This could include special

systems, spans, unique sections and other

structural benefits.

Concrete form liners, aesthetic shotcrete surfacing, and concrete staining methods were used on various areas of the project to allow these facilities to blend in with the surrounding environmental features and provide industrial functionality without disrupting the natural setting.

4. Did the concrete include itself into LEED

credits?No LEED Credits for the project. However, the project will provide green power to approximately 3,000 homes delivered through customers including: CUWCD, Utah Municipal Power Authority (UMPA), Provo City Power, Utah Associated Municipal Power Authority (UAMPS), Lehi City, Springville City, Kaysville City, and Weber Basin Water Conservancy District.

INNOVATION

5. What material innovations were required in

the specification and implementation in the

field? This could include high performance

concrete, special reinforcing, coatings,

additives, etc.

Concrete placements for water retaining portions of the project included Xypex Crystalline Admixture to aid in waterproo�ng. Low density cellular concrete was utilized to �ll the annular space between the existing rock tunnel walls and the installed 84-inch diameter steel pipe.

6. What construction innovations were

accomplished? This could include special

forming, sequencing, scheduling, placement,

finishing, curing, etc.

Intricate scheduling and sequencing was required for concrete placements in accordance with the speci�cations, construction joint constraints, and required cure times in order to accomplish the concrete installations within the project schedule milestones.

QUALITY

7. What quality-consistency levels were

achieved? This could include mix properties

history, floor flatness, tolerances, etc.

Water tightness of concrete waterways, basins, and vaults required high quality concrete placement and curing methods using delivered concrete materials within a tight speci�cation requirements. Embedded piping and equipment anchorages required extremely tight tolerances for proper �t-up with piping and equipment for the technologically advanced power generation and distribution equipment.

8. What quality successes were achieved on this

project?All concrete requiring water-tightness on the project was completed and tested successfully as per the project speci�cations. All embedded piping and equipment anchorages were completed within required tolerances and subsequent piping and equipment installations were completed without any required modi�cations. The outcome of the new plant construction and appurtenances exceeded all expectations of the Owner and Engineer, with the completed plant considered the �agship facility for Central Utah Water Conservancy District.

BENEFIT

9. Owner testimonial of how concrete bene�tted this project may be submitted.
