How Do Articulating Booms Enhance Maneuverability?



The ultimate advancement in moving concrete has been the concrete pump.  The Conco Companies own an impressive number of different size pumps that gives us the opportunity to use the very best equipment available in the industry to meet the specifics of each job.

As the saying goes that you need to use the right tool for the right job so is it goes for concrete pumps.  Many jobs could not be done without the boom pumps that can reach up to 184 feet horizontally to place concrete on to the upper floors of today’s super tall skyscrapers but just as important to the industry are articulating boom pumps.    

Articulating booms known as roll-and-fold or Z-fold come in four-section multi-Z booms or five-section Z-Fold booms and offer a lot of versatility and a great working range.  These booms can maneuver around obstacles and be used to reach difficult places but still provide a good vertical reach (the exact amounts depends on the model).  Another advantage to articulating booms is even though they offer a long reach they are able to fold up to a much smaller size when transporting.   

One example of an articulating boom is the Putzmeister 28Z.  Conco thinks it is such an important addition to our booms that we have one in all of our pumping locations including the Seattle area.  The pump offers a smooth concrete flow while having the smallest front outrigger footprint of all models in its class.  Since the 28Z does not require a large vertical clearance to unfold, it can unfold inside of a building when a job calls for it.  The smaller size means it travels easily and can be set up quickly. 

These lighter and very resilient pumps can adapt to different loads and now feature longer straight pipe for a less stressful concrete flow and better wear on parts.  The multi-Z configuration can pump even if the boom is not fully extended and “their elbow-like joints, controlled independently by hydraulic cylinders, often allow the operator to place concrete at any point between the truck and the boom’s maximum horizontal and vertical reach.”

Conco Constructs a Floor Every Week!



As one of the foremost commercial concrete contractors in the business, Conco continues to innovate and develop techniques that allow us to deliver exceptional services to our clients.  Furthermore we fully recognize that extended construction times drive up cost so we have become experts in working efficiently and cost-effectively. 

With a well-earned reputation of meeting or exceeding deadlines, Conco is routinely brought in on projects that have an accelerated timetable.  Such was the case of 815 Pines, a luxury 40-story apartment building adjacent to the historic Paramount Theatre in downtown Seattle.  Owned by the Holland Partner Group, they were adamant that the project was finished on time regardless of weather conditions and the challenges presented by the small footprint and minimal lay-down area.

Conco’s task was to construct a complete floor every week.  The time-lapsed video link below demonstrates one week of the activity that took place starting at Level 34 pour-day right through to Level 35 pour-day.  It clearly illustrates how we successfully accomplished this huge undertaking.

A breakdown of how major tasks were managed throughout the 5-day week:

·         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.
 
Throughout the 815 Pine project, the 5-day cycle was accomplished with a single shift that stayed within the construction schedule and exceeded the expectations of the developer.  By consistently collaborating with general contractors and owners, Conco strives to find solutions that meet the demands of each unique project we provide services on.

For over 50 years, Conco has been providing premium concrete services and is one of the most trusted concrete contractors in the  Northwest.  We partner with clients on every project from the pre-construction stage right through to final completion to maximize efficiency and ensure goals and budgets are met.  Our concrete services include commercial, educational, parking and other construction development as well as public works projects.
