National Guard Readiness Center

National Guard Readiness Center

National Guard Readiness Center,Alamosa, CO

Planning for the building began in 2009. It is the fifth and final readiness center to be built with funding granted under the “Grow the Army” initiative. Davis Engineering Service teamed with the architecture firm Coover-Clark and other disciplines to complete this beneficial project.

Completed in September 2013, the building cost to complete brought approximately $8,320,000 into the local economy, with 75 percent coming from federal funds.

Located at 1877 Old Sanford Road, the 27,150-square-foot facility is the new home of the approximately 80 part-time and four full-time Colorado Army National Guard Soldiers from Company D, 1st Battalion, 157th Infantry.

The building houses two 1,300-square-foot classrooms and a 4,698-square-foot assembly hall, which is available for use by the community for local events.

Approximately 35 percent of the construction labor was provided by local firms, including all civil and electrical work, landscaping, concrete and plumbing.

Currently, the closest permanent readiness center to Alamosa is located in Pueblo, Colo., which is approximately 120 miles away.

Removal of an Overflow Structure in Hermit #4 Dam of Hermit Lakes Recreation, Inc.  Hinsdale County, Colorado

Improvements at Hermit #4 Dam consisted of removing a overflow structure and reconstructing the dam embankment. This will ensure failure does not occur through the old overflow structure.

Construction began on September 4, 2012. A Contractor had been retained by the Owner to perform the outlet structure improvements and general project coordination.  Water storage arrangements were worked out with a private irrigation entity and approved by the Division of Water Resources. Hermit Lake No. 4 normal water level was lowered approximately 4 feet before construction began. A cofferdam was built by the Contactor according to project specifications.. A member from Davis engineering Service, Inc. (DES) was on site for most of the project construction.

The only problem that was encountered during this project was the organic material that was found throughout the existing dam embankment where the overflow structure was removed. The only acceptable solution to this problem was to rebuild the dam embankment with borrow material rather than using the existing material containing organics.

The project went smoothly, with the exception of one minor. The problem was dealt with in a timely manner and a solution was implemented to ensure quality construction throughout the project. Everyone involved worked well together, and the main goal to have the project finished before winter weather arrived and wouldn’t allow access into the project site was achieved. Overall this was a successful project that was completed with high standard of quality in mind.

Construction was completed early October, 2012.

Overflow Structure Improvements at Hermit #2 Dam consisted of removing and replacing the existing outlet pipe along with removing and replacing the existing overflow structure with a new concrete outlet structure which includes a new outlet gate. This should allow easy operation of the outlet gate, and ensure failure does not occur through the outlet pipe.

Construction began on August 6, 2012. The project went smooth, with the exception of minor problems. Problems were dealt with in a timely manner, and a solution was implemented to ensure quality construction throughout the project. Everyone involved worked well together, and the main goal was to have the project finished before winter weather arrived and wouldn’t allow access into the project site.

OUTLET STRUCTURE IMPROVEMENT AT METROZ PARK, LOWER DAM Mineral County, Colorado

Outlet Structure Improvements at Metroz Park, Lower Dam consisted of removing and replacing the existing outlet pipe along with removing and replacing the existing outlet gate.  This should allow easy operation of the outlet gate, and ensure failure does not occur through the outlet pipe.

Construction began on July 18, 2011. A contractor had been retained by the Owner to perform the outlet structure improvements and general project coordination.  Flash boards were placed in the upper lake to help store some of the inflow.  A cofferdam was built, and a temporary bypass structure was installed in case of emergency.  A member from Davis engineering Service, Inc. (DES) was on site for most of the project construction.

The project went smoothly, with the exception of minor problems.  Problems were dealt with in a timely manner, and a solution was implemented to ensure the best quality was produced during the project.  Everyone involved worked well together, and the main goal to have the project finished before the weather turned cold and wouldn’t allow access into the project site was achieved.  Overall this was a successful project that was completed with high standard of quality in mind.
Construction was completed early September, 2011

Archuleta County 2011 Asphalt Preservation

The County hired DES to prepare construction documents and to oversee asphalt preservation on nearly 12 miles of roadway including Light Plant Road (CR 119), Capricho Circle, South Pagosa Boulevard, Buttress Avenue, Meadows Drive, Pinon Causeway, and a portion of North Pagosa Boulevard. The project primarily involved crack sealing, full depth patching, milling, asphalt overlaying, seal coating, and chip sealing.

Engineer’s Estimate: $ 1,028,179.65
Construction Bid: $ 1,059,510.47
Construction Cost: $ 1,003,296.19

As-built quantities were carefully monitored and appropriately compensated for, which ended up allowing the addition by change order of nearly $100,000 of maintenance work on Trujillo Road within the contract while still staying under the original construction bid amount.

Aspenglow Boulevard, Handicap Avenue, and Carlee Place

Aspenglow Boulevard, Handicap Avenue, and Carlee Place

This 2.0 mile project was designed in the winter/spring of 2010 for a spring 2010 bid for the County. As with the Park Avenue project, all of the subject roads had significant surface deterioration. The project consisted of various road settings, with Handicap being in a very residential area having nearly 50 driveways and residences to contend with. Aspenglow and Carlee were more “collector” types, with fewer driveways and residential obstacles.

A few grade and sight distance issues were remedied on Aspenglow, while a significant grade and alignment adjustment was incorporated at the Handicap, Pines Club and Carlee intersection. The grade of Pines Club was reduced from 12% to 8% in this area, and sight distance was improved at the intersection with Carlee. Another significant modification was the inclusion of curb and gutter on Handicap. The roadside ditches were discontinuous and non-functioning in the fairly built-out subdivision, as evident in the photo to the right. It was obvious during construction where water was impounded as significant soft areas were stabilized along the edges. Again road widths were maintained between the Local Access and Collector County Standards to utilize existing road beds, have safe widths for the intended speeds, and discourage high speed use of the improved roadway. The project was substantially complete within the allowed contract construction period.

Engineer’s Estimate: $2,107,725
Construction Bid: $ 1,756,446
Construction Cost: $ 1,492,904

Again detailed bid schedules and the economy allowed for very competitive prices to be provided by the Contractors. Around $100,000 was saved on the project by utilizing a Tensar Triaxial Geogrid®, allowing us to reduce the structural section of the road (asphalt and gravel). The remaining savings against the bid result from construction review and contract administration and ensuring that unnecessary or unused items were not paid for.

Lewis Street Reconstruction (1st Street to 4th Street)

Lewis Street Reconstruction (1st Street to 4th Street)

This three block urban reconstruction project was pursued for the Town and designed in the 2010/2011 winter for a spring 2011 bid opening. The 400 block of Lewis Street had been designed by DES and constructed a few years earlier. The Town used their local preference policy and a longer construction period to encourage local contractors to pursue the three block project, desiring to keep the significant construction money in the community. This worked, with essentially a joint venture occurring between three contractors (one from Monte Vista, and two from Pagosa Springs) winning the bid. The street was completely reconstructed, and included significant on-street parking improvements, the addition of some underground storm drainage to minimize winter icing, and sidewalk on the south side of the street for the entire length to provide safe pedestrian handling which was deemed a priority as the Intermediate and Middle Schools are located on the south side of the 300 block. The project construction was initiated in the fall of 2011, and substantially completed in the fall of 2012, with some punch-list and minor items finalized in 2013.

Engineer’s Estimate: $ 1,612,191
Construction Bid: $ 1,318,044
Construction Cost: $ 1,336,835

Allowing the extended construction schedule enabled local contractors to construct the project at a very reasonable price. Construction costs were maintained near the bid amount, while balancing out unused quantities or items with the addition of extra sidewalk, access modifications, and other improvements desired by the Town, such as street lighting in the 300 block. For Town project reference, please contact Mr. James Dickhoff, Town Planner at 264-4151 extension 225.

Park Avenue, Cloud Cap Avenue, Holiday Avenue, and Masters Circle

Park Avenue, Cloud Cap Avenue, Holiday Avenue, and Masters Circle

Park Avenue, Cloud Cap Avenue, Holiday Avenue, and Masters Circle

The 2.1 mile Park Avenue and Cloud Cap Avenue project was fast tracked for Archuleta County through the engineering design process, with engineering notice to proceed issued on April 2, 2009, the design completed and submitted for County review on May 11, 2009, and the construction bid opening held on June 2, 2009. A 0.6 mile addition to the project consisting of Holiday Avenue and a portion of Masters Circle was designed and included as a change order to the Park and Cloud Cap Avenues project. All of the roads had significant surface deterioration, (as shown in the photo on the previous page) along with various sub-grade, alignment, and drainage issues.

The project was pursued as a “resurfacing” endeavor, attempting to utilize existing road section materials to the maximum extent practical to minimize costs. To accomplish this, the road section width selected was between the Local Access and Collector County Standards. At this width a safe, comfortable road could be designed for the desired 30 mph speed, and import of materials and modification to roadside drainage could be minimized. The project was completed on time and under budget.

Engineer’s Estimate: $ 2,833,912
Construction Bid: $ 2,321,592
Construction Cost: $ 1,997,174

Preparing accurate project quantity calculations which were incorporated into detailed bid schedules combined with the state of the economy allowed the project to be bid very tightly by the Contractors. The three low bidders on this project were within $48,000 of each other on the base bid. Project oversight and contract administration by DES kept construction costs down by maintaining constant review, minimizing change orders, and eliminating sub-grade stabilization and extra aggregate materials where not necessary.
