Current Happenings and News

December 10 - 

Concrete crews have been working on pouring another quarter of the floor today.  The concrete is curing slowly.  Crews will need to work until approximately 9:00 PM tonight to get the finish work completed when the concrete is at the right consistency.

November 30 - 

The crews have been busy setting forms and tying rebar in anticipation of the big event - pouring concrete!  This first pour will be for the floor of the reservoir.  Concrete trucks will start arriving at 8 am on Monday, December 3rd.  There should be 15-16 trucks throughout the day.  There will be a few additional vehicles on site and parked around the site as the concrete work is being completed.  On street parking is being directed to the north of the site on Faris Street. 

November 19

The earthwork contractors, Landis & Landis are moving their equipment out for a while to make way for the concrete crews.  During this short week, the construction crews will be moving in a crane truck to assist with moving materials around, framing concrete forms, and setting and tying rebar for the first of four concrete pours to for the reservoir floor.  Expect deliveries of rebar throughout the week of November 26th through the 30th.  If the weather cooperates, it is expected that the first concrete pour will happen on December 3rd or 4th.

The afternoon of November 27th will see traffic disruptions on Verlie as a generator for the Pump Station will be delivered and placed on site.  Flaggers will be out that day from about 12:00 pm-4:30 pm.

On November 9th, officials from the City of Happy Valley had their first chance to see the project up close and personal, from the floor of the reservoir site.  Brett Sherman, Stephani Hern, Steve Campbell, and Michael Morrow joined SWA Board members Ernie Platt and Chris Hawes on a brief tour of the construction site and had a chance to talk to Dan Fraijo, the SWA project manager, about the process to date and the process going forward. They all agreed, it's one big hole.

November 8

The last load from site excavation left yesterday and the large excavation equipment will be leaving the site over the next couple of days.  Rock for leveling the base is coming in and will be leveled and compacted.  The vibratory compacter will be working Thursday and Friday to set that base rock.  Placement of the inlet and outlet pipes and pouring the concrete blocks to secure them is scheduled for next Tuesday. Deliveries of materials for forms and rebar will be the most common heavy construction traffic for a while.

September 28 Update - 

Work has been slowed tremendously by more, and denser, rock.  There is about 5 more feet of material to remove to get to the right depth and it is all pretty solid rock.  This is bad news for the project schedule, but will assure that the reservoir has very good seismic stability.  Crews will be working on Saturday to complete installation of the erosion control measures before the October 1st deadline.  

A design change is in process for the retaining walls.  Rather than drilling anchors into the hillside and building a free standing retaining wall, the geotechs have determined that the rock is solid enough that affixing a steel mesh to the face of the excavation and spraying on grout will provide a solution that is just as structurally sound at a lower price for the agency. 

Traffic issues have plagued the project this week.  In addition to materials delivery and employee vehicles related to the reservoir project, the long delayed installation of a back up generator for the pump station was started. A conversation with the contractor has resulted in a plan to park employee vehicles off the street that should be implemented next week.  Delivery of some materials and supplies will still disrupt traffic temporarily on an intermittent basis.

Construction Update

More rock has been removed and there's about 11 more feet of digging left to go.  Since the hole is getting so deep, it has reached the point where the construction of retaining walls will be necessary.  Installation of the anchors for the walls was started on September 21st and will pick up again on Monday the 24th.  No weekend work has been slated for this week.

Update

Work progress has slowed dramatically as all of the easy-to-dig soil has been removed and the contractors started into the rocky layers.  So far, hydraulic breakers have not been necessary to this point, as the contractors have been able to rip the rocks out with standard excavators, although not without some additional effort and noise.  The hope is that similar conditions will remain as they excavate the final 10-12 feet.  The amount of material removed from the site is now over 44,000 cubic yards.  

The race is on to finish the excavation and try to get the floor poured before the rainy season begins.  The contractor will also begin preparing the site for the oncoming rainy season by increasing erosion control practices on site, such as plastic sheeting on steep slopes, diversion dams around the top perimeter of the excavated area, and other measures.

Weekly Plan
For week of August 13 - 17

Hauling on 147th Walking path is concluded.
Complete the common excavation (i.e.dirt)
Begin rock excavation - The reports are that the rock should be friable enough to rip out with the excavator.  If this does not prove to be the case then hydraulic breakers may be required,

Project Update
Just under 34,000 cubic yards of material has been removed from the site and is stockpiled at the Sunrise property on 172nd and Armstrong Circle.
It took an average of 52 seconds to load each dump truck.

A non-injury safety incident occurred at the job site on August 9th. A spare on-site truck was being used to haul asphalt debris as the crews cleaned up the 147th walking path after the excavators moved down into the hole.  In what appears to be a mechanical malfunction with the emergency brake, the truck rolled down the hill and went through the temporary fencing and into a home's yard.  Fortunately no one was hurt.  The contractor closed the site to normal work today while a complete safety incident investigation is conducted.  That truck has been removed from the job site.

Weekly Plan - 

For the week of July 30 - August 3

Soil removal will slow a little as excavation shifts to establishing the lower haul road and construction access.

A job shack for crew will be brought on site.

A fire hydrant at the site will be removed.

Project Update:

As of July 27, over 20,000 yards of soil has been excavated from the reservoir site.

Weekly Plan - 

Expected Work for Week of July 16-20

  • MOVE LOTS OF DIRT!

Update on work completed - 

To date more than 7,500 cubic yards of dirt has been removed from the site.

The construction entrance and erosion control measures have been installed at the stockpile site on 172nd Avenue and Armstrong Circle.

Due to the depth of the excavation, the contractor will be removing soil from the top of the site using old 147th as access for a period.
