815 Pine Full Deck Cycle Time Lapse - Seattle, Washington

Conco is often asked to accelerate the construction process in order to get a project to market rapidly. A case in point is 815 Pine, a 40-story residential tower in downtown Seattle, owned by the Holland Partner Group. The owner was adamant that the project was to be built on time regardless of weather conditions in the ever-changing Seattle market.
Conco was tasked with constructing a complete floor every week. This time-lapsed video of Level 34 pour day through Level 35 pour day illustrates how we have accomplished this. Major tasks completed by day were:
Day 1: Pour slab, core slab, walls, & columns. Start framing Level 35 deck.
Day 2: Jump core form. Strip columns. Complete L35 deck. Charge boundary elements. MEP layout.
Day 3: MEP layout. Edge forms. PSR rail install. Core rebar install. Bottom mat rebar.
Day 4: Perimeter panels jumped. PT install. Core walls complete.
Day 5: MEP/Pex pipe installed. Top of slab formwork. Embed installation. Charge column rebar cages. Clear deck, prepped for pour.
In the case of 815 Pine, a 5-day cycle using a single shift fit the construction schedule and exceeded the expectations of the developer.
Working with general contractors and owners, Conco strives to find solutions that meet the demands of each unique project for which it provides services.

Can’t believe how quickly you’re setting form work up on green slab for next lift. Organisation must be spot on. Well done 👍

This small project and space easy work.

How big and thick are those columns 👍👌👍👍👍👍👍👍👍👍👍

I used to love doing these placing boom jobs. From the decks to columns to core walls. Each and every pour was a exciting way to see the city and get new perspective of the real way to do professional construction with all the trades! I miss it now that I’m retired!

I'm a placement boom operator loooonnnnggg hours great job delicious $$$$$ cheers to you pumper

[@jacklaher5065]

Quite the load being place on a PT deck before it is stressed. Must be special provisions in the specs.

[@jakedehnert7936]

Let's not forget a pat on the back to the plumbers at Stirrett Johnsen for helping pull that off.

[@ahmedkamal7738]

Wonderful video great job

[@drewstrom75]

What I find most interesting is the placement (and replacement) and use (or lack of) of the porta-johns.

[@alkifxns]

Incredible!!..

[@marlineharrold1937]

wonderful video.

These guys need to come to Detroit on the Hudson site. They are taking forever compared to this. They just switched from steel to concrete about a month ago and barely went up 1 floor. There is two buildings but the shorter one is structurally topped out at 12 floors while the actual tower is going to be 49 floors. Ground was broken back in 2017 and they started with the old pit from the Original Hudson Department Store that at one point was one of the largest in the world.

there are moments that you see before handrail was put up past the decking level where they really should be tied off. Have I been somewhere where I should have been tied off but wasnt, sure, but i have also never worked on a building this high up. lots of respect but we should be a little more active with safety.

I Adores this work

[@Cdplayr69]

wow very cool

[@sandip0sheta]

best work

[@souchakriya9979]

Impressive. How about PT stressing? When will you do it?

[@susanaapolayo]

bellaquera!

[@jeffreyloftus3617]

There seems to be a lack of rebar in the deck slab with the centres appearing to be over two foot !

[@breakingrefractory5967]

jeffrey loftus post tension slabs generally have less rebar

[@timwalcott3169]

jeffrey loftus that’s where post tension cables come in !

[@seangreene64]

That’s why these dam monstrosity are falling apart.

[@mattwind8259]

Great job, was as a set accelerator used for the mix on this project? What was this slab area?thickness?

[@h1ph0pjunk1e]

had to have set for sure or elese vertical cant get pourd after the slab

[@kurulusosman8727]

😍😍😍

[@angeloacosta9411]

Porta-john is on the floor below...

[@SandipKumar-nd9fl]

concrete is good meterial for building construction

[@pdemont8854]

I see the concrete pump. How is it loaded?

[@pixelbender896]

It's a shaft boom loaded from the bottom

[@sahilturgut7561]

me opt con....Boom.. plac..

[@fabientre2800]

Wouldn't precast columns be much more efficient?

[@MsALIE1015]

What is PSR rail?
