What got me started working on Construction Problems

My dad was a Civil Engineer and worked for CalTrans. So as a child I was exposed to being a survey monkey holding the stick in the backyard as my dad word survey fence lines, drainage, concrete pours. My dad taught me trigonometry when I was in 3rd grade. At the time I didn’t think that my dad wanted me to be a civil engineer too. When it came to deciding what I wanted to be and study my choice was Industrial Engineering where skills in science, mathematics, finance, and operations came together. 4 years at CAL. 26 years at HP, Apple and Microsoft where I could use the IE degree. Don’t know what I would be doing if I was a Civil E. Maybe working on construction.

My first exposure to data center issues came when i met Mike Manos over breakfast and he wanted me to work for him. And that got me started working on data center issues that needed to be communicated. This is when I was developing the media role. Next i met a general contractor executive who was working on the first eBay data center and they needed help on the media strategy. This is when I got an inside look at how a GC worked. Taking trips to HQ, sitting in meetings, listening. And figuring out that this a completely different world where words meant different things. Or what the GC considered technical leadership was not in the world of technology.

One example is when the GC was excited to show its integration with Sharepoint and Office products. I told them NO. This is eBay. The data center team is anti-Microsoft. It is about open source software. What’s that? OK. Talk about the building problems you are solving, but don’t say Microsoft. Got it.

After I felt like I learned enough at the GC I switched to work with eBay as a consultant for Olivier Sanche. Olivier passion for green data centers is where we spent a lot of time, and we chatted about his going to Apple his dream job and asked me what it was like to work there.

Going to conferences I met all kinds of GCs, AE, commissioning companies, electrical, and HVAC companies blogging about how they fit in green data centers. While doing this i was understanding each of how these pieces fit together. Next it was the real estate companies and developers. With a picture of how the all the pieces interact including servers, networking, software, Cloud, IOT, AI, ML. etc I could see the problems.

Things like why Lean Construction doesn’t work near as well as as how Toyota Way impacts Toyota. Revit should be the big enabler for BIM, but when you dive down deep into how the Revit data format works you find critical flaws. Stuff that are like the file format nightmares in the Mac OS and Windows OS which is part of what I got exposure working as a project manager on System 7 and program manager on Windows NT.

Just like the GC who wanted to talk about technology to sell how good they are, the issue is people don’t see the right problem to solve.

Steve Jobs and Bill Gates were phenomenally good creating Apple and Microsoft because they prioritize the right problems to solve.

I can thank Mike Manos, the eBay data center GC, and Olivier Sanche for getting me started to understood construction. The nice thing is working on solving the construction problems has expanded what I look at beyond data centers. Navigating getting PR approval to discuss projects is not easy. It is what I used to do as part of a media strategy. So talking about projects that are over 8 years old is what I can do for now.

What I can do is write about general issues not specific to any current project.

Adding the other stuff to construction and wireless

Making construction information system works requires wireless. Well you can try it without wireless and you will not get far. To get wireless to work there is a lot of details you need to work on. Like how do you divide up the wireless Internet connection between the different users and their devices.

Let’s go through this example. I’ll be using my home business network as an example. I have a 150 mbps Comcast business connection. I have 7 WiFI access points in three different buildings all tied together into a wireless controller. Why a WiFi controller? Because that is how I get the performance data from each of the wireless access points and can see the wireless connections to each device.

Before that is an open source router, pfSense. On pfSense you can run traffic shaping.

Traffic shaping is a bandwidth management technique used on computer networks which delays some or all datagrams to bring them into compliance with a desired traffic profile.[1][2] Traffic shaping is used to optimize or guarantee performance, improve latency, or increase usable bandwidth for some kinds of packets by delaying other kinds. It is often confused with traffic policing, the distinct but related practice of packet dropping and packet marking.[3]

When I first turned off traffic shaping the test to see how well things work is how well did my son’s xbox games play. He was beating his friends playing a range of games, because my son now had a dedicated bandwidth so he was not dropping packets if the network was being hit by other high traffic loads.

Most consumer solutions WiFi will maximize speeds for a given user to allow speedtest numbers to be as high as possible. When I run a speed test I’ll get numbers below the 150 mbps limit as the traffic shaping software manages how much connection any one device can get and makes sure there is capacity in reserve for higher priority uses like VOIP or video calls.

This is just one example of the other stuff to discuss to make wireless work in construction.

Time to change what I write on this blog, semi-retiring the media role

I haven’t been writing on this blog as much as I have in the past. I resist the urge to switch to Twitter, Facebook, Medium or other publishing platforms.

This past week an executive at one of the big data center companies was promoted to a VP of technical communications. I reached out to congratulate the executive as it has been a pleasure to see him rise at the company.

Having the media role I have made great friends in the industry like GigaOm. Many of the other data center and technical publications. But, I have been getting bored of the data center news. I started writing about Green Data Centers because no one was discussing the topic. Now all the big companies Microsoft, Apple, Google, Facebook, and even Amazon have green initiatives as part of their data center efforts. No one talks about PUE because it is already a standard metric to measure efficiency of electrical and cooling systems.

During the break from blogging I have gone back to what I really enjoy. Solving tough problems. Writing about green data center was a tough problem. Now it is easy. It is boring, but at the time of figuring out how to write about a technical issue it was a challenge. When I started it was hard to get an answer to how much power was used by the cooling system. How much was is used by the cooling system. What drove me is the problems that it was hard to get an answers.

So what am I focusing on now? Two things. Construction processes and Wireless.

10 years ago I worked extensively on the eBay data center and GC Skanska. At first I was hired by Skanska to work on marketing and public relations issues, and they quickly found out that I knew way more technical knowledge. Spending 26 years at HP, Apple, and Microsoft being an industrial engineer working on quality control, manufacturing, distribution logistics, procurement, OEM program management, peripheral product development, System 7 software development, TrueType, Windows program manager, Interactive TV, Windows Technical Evangelism, Windows Server program management, and Systems architecture gives me a broad background to dive into almost any area I choose.

What I found phenomenally interesting is how a GC worked. After working with Skanska, I spent lots of time talking to friends at Turner Construction and gradually understand the world construction and how it worked. And I would talk to friends at Syska and CH2MHill. Many of these conversations would be ones at the conference hotel bars or hallways of the conference. With these conversations I figured out there was a need for a better construction application. The insights of building a construction mobile application with backend AWS infrastructure is a longer post that is complex to explain and probably put most of you asleep. I know when i tell my family the story they go to sleep.

But out of that boredom, realized that is mind numbing hard to do. There is something that needs to be done to make it easier. And that led me to wireless and what could be done.

I hope to write a lot more that I semi-retired the media role and I will write about construction and wireless.

Note: when I first wrote this post I said I was retiring the media role, but after reflecting a bit it is more like semi-retirement. It is no longer a focus to be a media person. I can still do it. More as a hobby. I am spending more of time as an engineer which is what I have done more of my life. Focusing on media gave me a chance to focus on the challenges of communicating.

Bottom line of Elizabeth Holmes Saga, a clueless inventor

Elizabeth Holmes Theranos Saga is top news with the HBO documentary release.

The best scene I liked was at the 26:45 mark when Dr. Phyllis Gardner, MD professor of Medicine, Stanford University comments on meeting with Elizabeth Holmes in the early days.

in that scene Dr Gardner explains that “it’s impossible, physically”

Eiizabeth continues her pitch to others and she makes it seem like she is the next Steve Jobs or Bill Gates.

I worked at Apple when Steve was there. I worked at Microsoft when Bill Gates was there. From watching Elizabeth Holmes her thinking that she can do something physically impossible is clueless to what Steve and Bill were able to do. They were phenomenally good at identifying where there was business opportunity and to get a team of people together to build to solve the technical issues to get to market.

Elizabeth raised lots of money. Sold her vision of changing the world. Then expected the believers at her company to do the impossible. To recreate physics to achieve her vision of how science works.

It’s like Elizabeth thinks she discovered the alchemy of blood science to take a few drops of blood and change medicine.

It’s been proven that Elizabeth was a clueless inventor. She had no scientific background for her invention. Her patents were part of the con game. Watch the HBO documentary it has good lessons. I used the time watching the video to be in yin yang mode. Elizabeth was telling lies. I was focusing on telling the truth.

I wonder how much time you could say Elizabeth told the truth. She believed she was telling the truth, but when you are clueless how do you know what is true?

If you want an inner view of the whistleblowers highlighted in the documentary check out this video with Tyler Shultz and Erika Cheung at Stanford on Feb 19, 2019. It is nice to see the whistlerblowers are in good spirits surviving Theranos.


A dear friend David Schirmacher has passed

7x24 Exchange’s President David Schirmacher has passed.

It is with profound sadness that I share the news of the passing of the President of 7×24 Exchange International, David Schirmacher on January 30th after a recent accident. We are deeply saddened by this tremendous loss. We extend our deepest sympathies to David’s wife Veronica, his brother Axel, his family and friends.

I have had so many hours of conversations with David I don’t know what to write. Yet I have written so many times about conversations with David. Writing about the end of conversations is so much harder.

One of the last conversations I had with David is his new data center metrics. Without David’s thought leadership the metrics will fade, but my memories of David will not. I can hear his voice in my head. I can hear his laugh. His quick wit.

Hearing about David’s passing I immediately thought of his wife Veronica who is an empty house. David’s presence was always a pleasure and I cannot imagine how Veronica feels in her house now.

Last night when i first heard the news and I checked in with friends who I know were close to David, and this morning I checked in with a few others. If you want to send sympathy wishes you can send them to Veronica at

Sympathy or Mass cards ONLY can be sent to:
Veronica Schirmacher
1573 Redwood Grove Terrace
Lake Mary, FL 32746

No flowers please.

When attending 7x24 I got in the habit of staying after the Wednesday presentations to have a burger with David by the pool. David was always busy at 7x24 and the time to chat with him would be after the conference was over. It is hard to accept I’ll never have another burger with David.

I wish i could write more, but it is so hard. It is hard because it hurts to think David is gone.

David will be missed my many.

May his soul rest in peace.
