9/17/2021: The west end connection on Clark Street along with all remaining sidewalk sections were poured this week. Work items next week include backfilling/prepping disturbed areas for sod/seed, placement of mailboxes, site cleanup and street sweeping. The intent is to reestablish through traffic in Stage 1 by the end of next week barring extremely rainy conditions or any unforeseen circumstances between now and then. Look for notification in the mail next week regarding an on-site meeting with residents scheduled for Wednesday evening, September 29th.
9/10/2021: The majority of sidewalk sections between drives on the south side of Clark Street were poured this week. Remaining sections between drives on the north side of the street and on the NW 105th Street cul-de-sac are being formed up and are expected to be poured back next week. The connection pavement on the west end of the stage near the NW 107th Street intersection has also been graded out and is also expected to be poured back one half at a time next week. No on-street parking will be allowed and mail will continue to be delivered to temporary gang locations while the remaining work is completed.
9/3/2021: All driveway approaches were completed earlier this week. As a result, access to individual residences in Stage 1 will be reestablished this afternoon at approximately 4:00 pm. Access will need to be gained from the east end of the project limits near the NW 105th Street cul-de-sac. Closures will remain in place at the NW 106th Street intersection (north leg) and the NW 107th Street intersection (east leg) until all remaining work items have been completed. These major remaining work items include the following: connection pavement on the west end of the stage near the NW 107th Street intersection, all remaining sidewalk sections between driveways, ADA sidewalk ramps to the street and backfilling/restoration of disturbed areas. No on-street parking will be allowed and mail will continue to be delivered to temporary gang locations while the remaining work is completed. Residents are encouraged to exercise caution and limit trips if at all possible as workers and equipment will be present in the construction area during the work week for the foreseeable future.
8/27/21: The majority of new driveway approaches will be poured by the end of day tomorrow. Sidewalk sections between driveways, ADA ramps to the street at intersections, the east connection at the Clark and NW 107th intersection along with any remaining driveway approaches are expected to follow next week. The intent is to have driveway access restored for residents in Stage 1 by the end of next week barring extremely rainy conditions or any unforeseen circumstances between now and then. Work in additional stages of the project yet this year is not anticipated at this time. A more formal notification will be provided all residents in the project area in the next few weeks after further discussions with the Contractor and impacted private utility companies.
8/20/2021: NW 105th Street mainline was paved today. The east connection on Clark Street and several intake boxouts were also poured earlier this week. Rough grading behind the new back of curb on Clark Street in advance of driveway and sidewalk construction was also completed. Subcontractor crews are expected on-site early next week to begin forming up and pouring new driveway approaches and sidewalk sections.
8/13/2021: Clark Street mainline was paved today. Crews are hopeful to pave the NW 105th Street cul-de-sac next week after trimming the rock subbase in this area. Also starting early next week, driveway and sidewalk approaches adjacent to the new pavement on Clark are expected to be graded and prepped for paving.
8/6/2021: Rock subbase was placed on the grade earlier this week. Trimming operations are expected to follow early next week prior to the start of mainline paving.
7/30/2021: Subgrade treatment/testing and subdrain construction was completed earlier this week. Rock subbase material is expected to begin being placed early next week with paving crews expected to mobilize to the site before the end of the week. The first task for those crews will be trimming the subbase to finished grade prior to the start of mainline paving.
7/23/2021: Water main testing was completed earlier this week. Final cutovers to the City’s existing water system and service line connections to individual residences have also been made. The subgrade treatment contractor is expected on-site early next week followed by subdrain construction at the future back of curb. Once subgrade testing has passed, the subbase rock will be placed and trimmed.
7/16/2021: The subgrade has been trimmed to finished grade and it will be treated once testing of the new water main has been completed. Once these water tests have passed hopefully by mid-week, individual water service lines will be connected to the new main and subgrade treatment operations can begin.
7/9/2021: Water main testing will continue into next week. The majority of storm sewer construction (pipe and intakes) was completed this week – pouring inverts and backfilling structures will be completed early next week. Finish grading and subgrade preparation operations are also expected to be underway next week.
7/1/2021: Storm sewer structures are currently under construction at the intersection of NW 105th and Clark. Remaining storm sewer pipe is scheduled to be laid west out of the NW 106th St intersection yet this week with all additional structures expected to be completed by the middle of next week dependent on weather. Bacteria testing on the new main did not pass earlier this week so the pipe will be rechlorinated and retested early next week. The majority of service lines have been stubbed to the new main for connection once testing is complete. These are the last remaining underground utility items remaining in Stage 1. The City and Contractor are hopeful that grading and subgrade preparation work will be able to proceed the week of July 12th.
6/25/2021: The new water main is in place and currently undergoing testing procedures prior to the connection of service lines to individual residences. Storm sewer construction also continued this week, but periodic rain events throughout the week did not allow for storm sewer structures to be poured as originally scheduled.
A note regarding project schedule. The initial indication when construction started earlier this year on April 5th was that work in Stage 1 would take approximately twelve weeks to complete. Today marks the end of the twelfth week of construction. The delays experienced to date are directly related to the number of existing utilities (public and private) that the Contractor has been required to work around on a daily basis. This is a reality when undertaking a complete reconstruction project in an already developed urban area and was not entirely unexpected. Similar issues were experienced on last year’s project further to the east on Clark Street. Map locates for all affected utility companies were provided during the design process and identified to the greatest extent possible on the final plans. Some relocations of private utilities were completed this spring prior to the start of construction and others have been scheduled and will continue to be scheduled as needed during construction. With the sheer number of utilities involved, it was not possible to relocate every single one prior to construction in order to provide a “clear” job site for the City’s contractor to work in.
Looking forward, the Contractor is hopeful that the remaining underground utility work in Stage 1 can be completed in the next two weeks (approximately July 9th). At that point, the paving subcontractor will need up to five weeks (approximately August 13th) to complete mainline paving, sidewalks and driveways prior to reopening Stage 1. These dates are best approximations based on how things have proceeded to date and do not include any future loss of time due to extended periods of inclement weather or any additional delays out of the Contractor’s control.
6/18/2021: Storm sewer and water main construction has been ongoing this week and is expected to continue next week. A conflict between a proposed storm sewer line and an existing section of water main will require an additional water service outage next Monday, June 21st for the residents in Stage 1 (11 total). The Contractor delivered door hangers to all impacted property owners today outlining the expected timing and duration of this outage. Once again, there may be air in the water service lines during the first use that will need to bleed out once the work has been completed. In very short order, the system should function normally with no other long term affects or complications.
6/11/2021: Both water main and storm sewer construction will continue next week. Work areas include the water main on the west end of the stage past NW 106th Street and storm sewer primarily in the NW 105th Street cul-de-sac.
6/4/2021: Water main construction has been ongoing this week and will continue into next week. Testing of the new main will follow with the focus of underground utility work then moving to construction of storm sewer pipe and intakes.
5/28/2021: The water main connection on the east end of Stage 1 was successfully completed this past Monday. Sanitary sewer construction in Stage 1 was also completed earlier this week. Next week, water main will continue to be laid west towards NW 107th Street and north up NW 105th Street.
5/21/2021: Progress was hampered this week by persistent rains. Sanitary sewer construction is nearing completion and materials for water main replacement have arrived on site. The first step related to water main work will be a connection to the new main from last year’s project just east of the NW 105th Street intersection. As a result of this work, residences in Stage 1 (11 total) will be without water service while this work is completed next Monday, May 24th. The Contractor delivered door hangers to all impacted property owners earlier this week outlining the timing and duration of this outage. Once the work is complete and the system has been reconnected, there may be air in the water service lines during the first use that will need to bleed out. In very short order, the system should function normally with no other long term affects or complications. Ongoing work once the connection has been made will consist of laying the main to the west on Clark Street and to the north on NW 105th Street as weather conditions allow.
5/14/2021: The last remaining run of sanitary sewer in Stage 1 heading west from the NW 106th Street intersection is expected to be completed next week. Once finished, the Contractor’s focus will shift to replacement of water main beginning once again at the east end of the stage near the NW 105th Street intersection.
5/7/2021: Sanitary sewer replacement operations continued this week, heading east towards the NW 105th Street intersection with additional services to individual residences connected as the work proceeded. Once the next manhole is set on Clark Street, sanitary sewer will be laid north up the NW 105th Street cul-de-sac to the last manhole on the east end of this stage.
4/30/2021: The Contractor continued with sanitary sewer removal and replacement operations this week between NW 106th Street and NW 105th Street. New sanitary service lines to individual residences from the new main to the back of sidewalk were connected as they were encountered during construction. Underground utility operations are expected to be ongoing for the next several weeks on Clark Street and NW 105th Street. Residents in this phase of construction who wish to participate in the annual Spring Cleanup scheduled for tomorrow should move their items to the NE corner of the NW 107th and Clark Street intersection. Please place items behind the back of curb this evening in order to minimize any additional on-street congestion. The hauler has been notified that there may be additional material placed at this location.
4/23/2021: Sanitary sewer replacement operations are underway at the intersection of NW 106th Street. Once the manhole in the intersection of Clark Street is set, the Contractor will proceed east towards NW 105th Street with this mainline sanitary sewer run.
4/16/2021: The delivery of pipe and structures to the job was unexpectedly delayed earlier in the week. Unfortunately, this delayed the start of underground construction. The supplier has now gotten enough materials delivered to the job site for sanitary sewer removal and replacement to start next Monday near the intersection of NW 106th and Clark Streets.
4/9/2021: The Contractor moved into the job site earlier this week and completed all pavement removals in the Stage 1 area. Progress was hampered by mid-week rains, but next week sanitary sewer removal and replacement near the intersection of NW 106th and Clark is expected to be underway.
4/2/2021: Absolute Concrete is expected to mobilize to the job site next Monday morning to begin pavement removals in Stage 1 of the project between NW 105th Street and NW 107th Street. Once the pavement is removed, their initial efforts will focus on sanitary sewer removal and replacement beginning at the intersection of Clark and NW 106th Street. MidAmerican Energy’s subcontractor who has been on site for the past few weeks will also remain on site working on gas and electric relocations in the City right-of-way between the back of curb and sidewalk.
3/26/2021: A virtual meeting with residents between NW 105th Street and NW 114th Street directly impacted by this year’s project will be held next Tuesday evening, March 30th at 6:00 pm. The Contractor’s anticipated start date is still Monday, April 5th.
3/19/2021: Absolute Concrete has been awarded a contract to complete the work on this year’s Phase 2 project between NW 105th and NW 114th Streets. Absolute has indicated that work in Stage 1 of the project between NW 105th and NW 107th Streets will begin on Monday, April 5, 2021. Residents directly impacted by this project should expect a mailing next week outlining additional project details. A virtual informational meeting to go over the project in greater detail is also expected to be held during the week of March 29th. Specifics on that meeting date and time will be included in the letter.
