KATO Road Grade Separation Retaining Walls Under Construction


 
 
 
 
As part of the BART South Bay Extension Project (SVRT) structural design team, Sierra Engineering Group is the engineer-of-record for the design the DSM (Dense Soil Mix) retaining walls for the subject project. Ultimately the concrete wall facing will act compositely with the steel soldier piles which are anchored to the wall with headed welded studs. Due to the sensitive nature of adjacent properties and utilities, we were charged with examining the wall behavior at various stages of construction. Our extensive analysis made use of the latest design software to accomplish this task, namely PYWALL as well as others. Construction is currently proceeding with the tiebacks already detensioned and the walls behaving as anticipated.  The majority of the concrete struts which span under the width of the future roadway are in place and placement of wall reinforcement under way.

In Honor of National Poetry Month - For Engineers

The Sons of Martha
by Rudyard Kipling


THE Sons of Mary seldom bother, for they have inherited that good part;
But the Sons of Martha favour their Mother of the careful soul and the troubled heart.
And because she lost her temper once, and because she was rude to the Lord her Guest,
Her Sons must wait upon Mary's Sons, world without end, reprieve, or rest.
It is their care in all the ages to take the buffet and cushion the shock.
It is their care that the gear engages; it is their care that the switches lock.
It is their care that the wheels run truly; it is their care to embark and entrain,
Tally, transport, and deliver duly the Sons of Mary by land and main.
They say to mountains, " Be ye removèd" They say to the lesser floods " Be dry."
Under their rods are the rocks reprovèd - they are not afraid of that which is high.
Then do the hill tops shake to the summit - then is the bed of the deep laid bare,
That the Sons of Mary may overcome it, pleasantly sleeping and unaware.
They finger death at their gloves' end where they piece and repiece the living wires.
He rears against the gates they tend: they feed him hungry behind their fires.
Early at dawn, ere men see clear, they stumble into his terrible stall,
And hale him forth like a haltered steer, and goad and turn him till evenfall.
To these from birth is Belief forbidden; from these till death is Relief afar.
They are concerned with matters hidden - under the earthline their altars are
The secret fountains to follow up, waters withdrawn to restore to the mouth,
And gather the floods as in a cup, and pour them again at a city's drouth.
They do not preach that their God will rouse them a little before the nuts work loose.
They do not teach that His Pity allows them to leave their job when they damn-well choose.
As in the thronged and the lighted ways, so in the dark and the desert they stand,
Wary and watchful all their days that their brethren's days may be long in the land.
Raise ye the stone or cleave the wood to make a path more fair or flat;
Lo, it is black already with blood some Son of Martha spilled for that !
Not as a ladder from earth to Heaven, not as a witness to any creed,
But simple service simply given to his own kind in their common need.
And the Sons of Mary smile and are blessèd - they know the angels are on their side.
They know in them is the Grace confessèd, and for them are the Mercies multiplied.
They sit at the Feet - they hear the Word - they see how truly the Promise runs.
They have cast their burden upon the Lord, and - the Lord He lays it on Martha's Sons !

Our word

Often we are asked how we market Sierra Engineering Group (SEG). Our response is simple; our marketing efforts are based on a single tenet: Trust.  Most engineering firms share similar claims; they provide quality work, excellent service, timely delivery and unparalleled expertise.  These proclamations are not likely to distinguish one firm from another.  Certainly they are all capable of all that they pronounce about themselves. We have no doubt about the integrity and ethics of our profession and remain proud to have chosen structural engineering as a career.  We all strive for the same thing. But how do we separate ourselves from others, how do we stand out.
At SEG marketing is about building relationships. However, in today’s economic climate, most end users tend to seek multiple proposals, a practice that has resulted in the commodization of engineering services. Our approach has seen diminishing returns yet we believe in its value and remain committed to it.
Years ago, I was recommended to an Architect by a contractor.  When I visited the Architect’s office, I noticed a number of multistory building drawings hanging on the walls.  After SEG successfully completed the project, I approached the Architect about the possibility of doing more work for them.  I asked specifically about the project types that were hanging on the walls.  He asked about our experience level with multistory concrete construction. I responded that ours was a young office and that although I personally had the experience, our staff was still evolving and their experience was not to the level required.  I was honest that as Principal of the firm my own time was limited and I was not able to lead the project myself. Impressed by my honesty, passing on a truly substantial project, he simply asked me to let him know when we were ready.
True to his word, about two years later I approached him again and simply told him we were ready.  He immediately awarded us with a project. To this day that Architect remains as our best and most loyal client.  Simple honesty gained their trust. 
At SEG, we consider our word to be invaluable. It is how trust is founded.  And trust is how lasting business relationships are built.

Doral Buick-GMC Expansion Nearly Complete












Sierra Engineering Group (SEG) served the structural engineer-of-record for this major addition and interior remodel of the Doral Buick-GMC Dealership in Miami, Florida, currently nearing substantial completion. The expansion calls for an additional 7,000 square feet of enclosed space to increase the showroom size as well as the service area.  It also included the expansion of a second level parts storage mezzanine.  SEG provided structural engineering design services as well as construction administration services during construction of the project.   SEG worked closely with Offerle-Lerner Architects and the City of Doral as well as the ownership to expedite the permit process.   The structural system includes the use of CMU perimeter walls and open web steel joists for the roof and floor framing systems.  Despite the unique phased construction, the contractor, AutoBuilders Inc. has managed to maintain schedule with minimal disruptions to day to day business operations.  It’s an example of how a good working relationship between the design team and the construction group can make for a successful project.
Structural Engineer: Sierra Engineering Group
Contractor: AutoBuilders Inc.
Client: Doral Buick-GMC
Construction Cost: $1.8 million

2995 Middlefield Completed


Sierra Engineering Group was the structural engineer-of-record for the recently completed office building at 2995 Middlefield in Palo Alto, CA.  Hayes Group Architect’s distinctive modern approach has resulted in a unique structure.  Though the footprint is limited, the lines expressed by the use of horizontal shade elements along the front façade and recalled along the south elevation’s triangular trellis evokes the image of a much larger structure, giving it a sense of belonging without overpowering the surroundings. Varying roof lines and the architect’s desire for shallow structure at the overhangs presented some unique structural opportunities.  Working closely with Hayes Group, we chose a horizontal steel truss system to brace the full height round steel columns along the Middlefield elevation. In keeping with the steel brace theme, the building’s lateral load resisting system makes use of a concentric braced frame system concealed within the elevator and stair walls, leaving plenty of room for the use of glass along the exterior walls resulting in an inviting interior space.
