WR1 columns almost complete; roof deck starts soon
Waluga Reservoir 1 Roof Replacement Construction Update
Crane delivery and removal
On the morning of Tuesday, January 31, a very large (360-ton) crane will be delivered to the site using several large semi-trailer trucks. Due to site constraints, and to minimize traffic impacts during delivery, trucks will be staged near the I-5. Only one truck will enter the site on Carman Drive at a time, unload crane materials and then exit, before another truck then arrives to the site. Five trucks are expected to deliver parts for the crane.
Please watch for flaggers and expect some minor delays during delivery.
Once the large crane is set-up, it will be used to lift the smaller crane out of the tank. Both cranes will then be dismantled and crane pieces will be hauled off-site by several large trucks.
This activity is expected to take about two days to complete. Neighbors should expect an increase in truck traffic on Carman Drive during this time.
Columns almost complete; roof pours begin soon
Crews are scheduled to pour the last six columns next Monday, totaling 52 new columns that support the new roof!
Work is underway on reinstalling shoring support to prepare for the new roof. This is expected to be complete by mid-February. Over the next two weeks, crews will also begin tying rebar, to form the new roof deck.
In mid-February, concrete placement is expected to begin for the roof deck. The roof will be poured in a checkerboard pattern, one quarter at a time. Each quarter will require 256 cubic yards of concrete to be poured, about 25 concrete truck loads in one day!
Neighbors should expect an increase in noise and truck traffic during concrete pours, as a large pumper truck and concrete trucks will be operating on site.
Over the next few weeks, neighbors can expect to see and hear a large crane operating overhead, concrete pumper trucks, concrete trucks and truck traffic carrying materials, crane pieces and equipment to and from the site during work hours.
Generally, work hours are Monday – Friday, 7 a.m. - 6 p.m., with some Saturdays, 8 a.m. – 6 p.m.
Pedestrian access safety reminder
Through spring 2017, there is no public access allowed on the site due to active construction. All pathways through the reservoir site are closed to ensure safety. Thank you for your assistance and patience.
