Urgent Bids and Budgets; The Engineers that Stole Christmas!


What is up with all these bids and urgent budget price requests before Christmas??
Some engineers and owners may not realize that we have kids in Christmas choir concerts and plays and end of year parties also…. I am in trouble with the wife because I have a sick kid on the last day of school so she wants me to go to another kid’s break up party because she can’t, but I have a bid today, one Monday and one Tuesday next week (12/23) that I need to get pricing and proposals together for…. Why does someone want bids on 12/23? Are the engineers going to go through them between Christmas Eve and New Year ’s Day? I bloody hope they are after I have busted my butt to get these together and not had a chance to enjoy all the buildup to the holidays...

And to the engineers who say “well if you can’t get the budget price by 12/24, can you get it to us by 12/31…. Yeah great, there goes the few day’s off I was planning to have with the family after the hectic bidding up to Christmas Eve. And this does not take into account a few projects I decided not to bid because of such a high workload this time of year.
It certainly is a good sign for the economy and the industry all of this bidding happening at once and I prefer too many bids than none. I understand there may be some budgetary reasons for needing these projects bid before the end of the year. If the project must be bid by year’s end and you want to get quality bids, my recommendation is you bid it late November or early December. Otherwise you may end up getting a conservative estimate because OEMs don’t have time to properly cost the project (and we are at the same time hassling our suppliers for quotes who would have the same gripe as us being flooded at the end of the year) and maybe getting high bids will defeat the purpose of trying to push the project through by the end of the year!

Manufacturers are from Mars, Engineers are from Venus!

Why bidding creates conflict and how it could be improved.
 
When I was asked to present the OEM’s perspective on Design, Procurement and Fabrication at the AMTA-SWMOA Membrane Technology Transfer Workshop this past July, I jumped at the opportunity as I had already started drafting this blog post related to the inevitable conflict that arises between engineers, OEMs, contractors and owners during the bidding process.

 The Design-Bid-Build process nearly always ends up being a win-lose relationship between OEM, contractor, engineer and owner. The biggest hurdle in turning around this win-lose culture is the fact the OEMs (and contractors) are from Mars and Engineers are from Venus, i.e. while we speak the same language, we don’t understand each other….

Honestly, I think all parties have good intentions but because they don’t understand each other there is a ‘protect your butt’ attitude throughout the procurement process from spec writing to post-bid submittals. And the tone is set by the way the specifications are written. Typically specifications are written so that the owner and engineer are protected from being ‘short changed’ by the contractor on the quality and functionality of the treatment process they have designed and wish to procure, and rightly so since they have designed the system and are looking to pay someone to build it.

Beware the Dreaded ‘Catch-all’ Statements
As a manufacturer, what is so frustrating are the ‘catch-all’ statements often embedded in very detailed specifications. For example, before tightly specifying every nut and bolt to be used, the specification prefaces the equipment design details by saying “the Contractor shall supply a complete and operable system including the following components….”. And then following the detailed specs it will say “The specified information does not relieve the Contactor of the responsibility to provide a fully operable system”. Can someone please give me a clear definition of a ‘complete and operable system’ because this statement is certainly open to interpretation.

I used this example in my AMTA/SCMA presentation; when my wife says she does not like the color of the living room, I am from Mars and think she wants me to paint it a different color. But I don’t understand that what she is really saying is the house is too small, she hates the new neighbors and she wants to move… How could I have not realized that by her initial statement?? Engineers and contractors/manufacturers have the same form of communication disconnect. When they write in a specification that it is the contractor’s responsibility to provide a ‘complete and operable system’ in addition to complying with a detailed equipment description and P&IDs, the contactor/manufacturer assumes if they provide what is in the P&IDs and is described in the detailed specs they will have provided what the engineer/owner requires. Wrong!

Cynically, you could say this is an insurance statement inserted by the engineer in case something was forgotten and the specifications were not watertight enough so that the contractor/manufacturer may cut some corners in quality.  Perhaps contractors/manufacturers are therefore partly responsible for these statements because of past practices. But these statements certainly set up the course of the project as a win-lose relationship.

I worked on a project where ‘complete and operable’ meant that since the CIP tank that was specified was 7ft tall, as the supplier of this tank we were supposed to interpret that we should also supply a platform for access…. As far as the contractor was concerned, he wasn’t supplying the membrane system, so that was our problem... We didn’t read all the details of the building specs, so didn’t know a platform hadn’t been accounted for. Was  there ever an intention that one of us was going to provide a platform or did the owner/engineer realize this was needed during the submittal phase and called in the catch-all insurance statement to cover their butt? In this case it wasn’t a big cost item and we sorted it out, but it is a good example of where the contractor/manufacturer can be trapped by vague specs.

Bid Counseling…
So how can we avoid this win-lose situation?  Let me be a project counselor for a minute and try to
get the parties to understand where each is coming from. Firstly Mr. Engineer; you have to realize when you set up a competitive bidding environment, a catch-all statement is not worth the paper the spec is written on! As a bidder, I cannot afford to include anything that is not specifically described in the specifications and hope to be selected. I am certainly not going to see a statement saying ‘complete and operable’ and think “Oh yeah, I should also include a platform in my pricing” and assume all my competitors will do the same. I am going to be out of business in a hurry in that case. In a competitive bid situation you have to assume the bidders will provide only what they have to because they will assume that is what their competitors will be doing.

From an engineer’s perspective, if there are some different options in products that can be used to meet a treatment objective making it difficult to write a fully prescriptive spec, then perhaps there should be a pre-procurement process where the engineer can evaluate proposals from process equipment suppliers and make sure there is an apples to apples comparison in scopes of supply. Then select the process equipment prior to going to contractor bid. That is typically how the microfiltration/ultrafiltration system bidding process works where historically the equipment design has varied between manufacturers (see Municipal Ultrafiltration Heads Towards Commoditization). The only thing a contractor can do if a bid spec is vague is provide the lowest cost option that appears to meet the specs or formally ask a question to have this clarified prior to the bid close. Whether the response will be provided in a timely manner or the question adequately answered is another issue, another opportunity for Venus and Mars misinterpretations and another topic I could dedicate a whole post to…

I don’t have a perfect answer on how to solve all the conflicts that arise from the design-bid-build procurement process. Don’t get me wrong and think I am putting the blame for the conflict on any particular party, as I think historically all parties have had some role in creating this win-lose, protect your butt environment. I have also participated in many projects where the relationship between engineer, contractor and equipment manufacturer has been great. For some of these projects we were given the opportunity to review a draft of the full set of specifications prior to the bid (and not just a few days before release), which was a big help in getting everyone on the same page on bid day.

Conflict does not have to be inevitable for design-bid-build projects but it will take a little more trust between the parties and a lot more communication throughout the project to avoid it. Don’t be afraid to involve manufacturers and contractors in the spec review process, then perhaps the catch-all statements would not be needed, plus they may actually have some good ideas that can save everyone some money – Heck, wouldn’t that be a win-win?!?

Ultrafiltration Module Market Still Hard to Grasp for Some


Encouraging Signs that Engineers/Owners are Gradually Catching On
Two recent RFPs for pilot studies for future large (30-50 MGD) MF/UF installations were encouraging in that they were open to piloting modules from some of the relatively newer market entrants, but also highlighted that there is still some work needed to educate many engineers and system owners on how an Ultrafiltration system is built using these modules. It really isn’t that complicated if you are familiar with the RO/NF market where the manufacturers of the membranes are suppliers to the OEMs/System Integrators who build the functioning systems and who bid the projects.

Dow UF Modules on a System Built by Wigen Water Technologies
One of these RFPs was for a large drinking water facility and it was sent out to the likes of Dow and Toray asking for pilot plant information and reference sites. Of course both of these companies then contacted my company (and likely other OEMs who have used their membranes) to see if they could use our pilot plant and provide reference information for the systems we have built using their membrane modules. We are now working directly with the City to conduct a pilot study with one of these modules.
The other RFQ is for a future large wastewater filtration system and the City has obviously made an effort to invite all of the MF/UF module suppliers to submit a proposal as well as the 'Big Three' membrane system OEMs. This RFQ is still not due for a few weeks and we have already been contacted by three of the module manufacturers asking if we will be submitting a proposal and if so, can we use their module. Obviously this City also does not understand that these module suppliers do not build systems and that they should be targeting the integrators who use these modules. What is really amusing about this RFQ is the scoring process that proposals will be evaluated by. Seventy percent (70%) of the evaluation weighting is based on the financial strength of the company and the strength of the reference list, with higher scoring for larger systems operating for longer periods. Why then waste time and effort in asking for proposals from anyone other than Pall, Evoqua and GE? Are these guys so ignorant that they don’t realize that systems using Dow or Toray modules have only been operating in the US for 3-4 years and are all less than 10 MGD and to my knowledge there are no significant sized systems using Hydranautics or Econity UF modules in the US? They would have to look to Asia or Europe to find any systems of significant size using these modules. I would want to get some sort of indication that the City would be waiving the selection criteria for one of the three pilots to consider something different before I waste any time in submitting a proposal here… At least the City has acknowledged that there are alternative MF/UF modules to those offered by the Big Three but if it is serious about looking at one of the alternatives, the City needs to get better educated on which OEMs/integrators have experience using these modules and develop a more realistic selection criteria that will give these OEMs a chance of being selected.

Despite the confusion over the membrane module marketplace, I do see a silver lining with increasing interest and acceptance of the non-proprietary membrane modules. It is still going to take a while for the majority of engineers and owners to ‘get’ how this new market works and the module manufacturers and integrators who use them need to work harder in educating these designers and end users.

The Times They Are A-Changin in the MF/UF Market!

Some significant projects awarded in the past few weeks are really going to shake up the status quo in the North American municipal Microfiltration/Ultrafiltration market.

First Contractor Bid Universal MF/UF Skid System
The 3 MGD Universal MF/UF Skid system for the City of SantaBarbara’s El Estero WWTP that first bid in late January, then rebid in early April after protests from contractors on technicalities on filling out the bid forms, has finally been awarded. To my knowledge, this is the first direct contractor bid for a Universal MF/UF Skid system. Several MF/UF OEMs were prequalified (Pall, GE, Wigen and H2O Innovation) and there were five MF/UF membrane modules listed from which the OEMs had to offer a MF/UF skid design that could accommodate three of these modules. The initial inventory of one of these modules was to be included in the equipment price and this module was to be listed in the bid form as well as two other modules that the rack was designed to accommodate.

The owner’s engineer, CDM Smith, predesigned and specified the backwash and CIP systems so that these would be suitable for all listed modules, allowing contractors to provide this ancillary equipment directly if desired. The winning bidder did choose to provide this ancillary equipment while selecting Wigen Water Technologies to provide the three 1 MGD UF skids, membranes and control system. The UF skids will be supplied with Dow’s IntegraFlo IW102-1100 UF modules (1103 ft2/module). This system is to be installed and running during the first quarter of 2015.
 
Inge Lands 30 MGD UF Project

And just when you thought the MF/UF module market was converging towards pressurized outside-in PVDF hollow fiber membranes, Inge/BASF is selected for a 30 MGD project with San Jose Water Company using its multi-bore inside-out, PESM UF membrane… After OEMs using Toray and Dow membranes have been steadily chipping away at the market share of the Big Three the past few years working their way up to system sizes of about 10 MGD, all of a sudden Inge comes out of virtually nowhere and lands a 30 MGD project at San Jose’s Montevina WTP. Inge has been prominent at the AMTA/AWWA Membrane shows the past few years and has now set up local offices on each coast so they did need to gain some traction in the US market soon, and with the Montevina WTP order they certainly have done that!
Inga’s multi-bore membrane looks like a very robust membrane that will have no integrity issues. How this membrane will fit in the emerging Universal Skid market is yet to be seen where the modules on universal skids have been outside-in. The integrator for the system using Inge membranes at Montevina is H2O Innovation who beat Pall for this project. I believe this was a preprocurement bid and only Inge and Pall/Microza membranes were considered, so well done to Inge in getting a seat at the table here.

With all of these changes in the MF/UF market, Bob Dylan’s song is certainly appropriate...
“Come gather 'round people
Wherever you roam
And admit that the waters
Around you have grown
And accept it that soon
You'll be drenched to the bone
If your time to you
Is worth savin'
Then you better start swimmin'
Or you'll sink like a stone
For the times they are a-changin'.”

AWWA/AMTA 2014 Annual Membrane Conference Wrap

Las Vegas was the venue this year and it looked like a record number of exhibitors turned up for the AWWA/AMTA Annual Membrane Conference in March. Maybe that is a sign that the economy is picking up and many more membrane projects are starting to move forward. There was certainly heavy attendance from Western U.S. where drought is driving interest in membrane project for reuse, brackish and seawater desalination.

Personally, I was so busy in meetings and attending to visitors at our booth, I hardly had a chance to tour the exhibit hall or see many technical presentations. With the conference in Vegas, delegates dispersed each night after the show so there also wasn’t as much of an opportunity to network and get some industry low-down as you do when the show is based in a venue with fewer distractions.


If there was one takeaway from the show, it is the growing interest in the universal MF/UF rack system. This was featured at booths of a number of OEMs and discussed in some presentations. It was also interesting to see new UF modules continuing to come on to the market. As an OEM, you have just got to select a few and base your design around these, even for a universal MF/UF rack. Having now designed a few of these, it is a lot simpler if the modules are similar in size (dimensions, port location and membrane surface area) where the smallest module drives the footprint of the rack, as well as uniformity in backwash and CIP requirements. If the universal rack concept takes off, I can see this driving UF module manufacturers to more closely align their sizing and operational parameters.
Desalitec seems to be making some inroads with their closed circuit desalination (CCD) process based on presentations and some press releases I have seen. The jury is still out with me as to whether CCD is just a niche applications or has potential on a larger scale. I also saw a really cool compact energy recovery device that can be used on smaller skid mounted RO systems. I am sure there were many other great technical innovations I missed and that deserve mention. Hopefully next year in Orlando I get more time to roam and mingle…

A Historic Week for UF/MF Market?

Game Changing Bid will Test Membrane Establishment against Rising Stars

A potential game changing bid this week could shape the future of the municipal MF/UF market in North America. Up for grabs is a 3-MGD MF/UF system consisting of a 'Universal Rack' that can accommodate 3 of 5 prequalified pressurized, hollow fiber, PVDF membrane modules. This will allow the water utility to competitively bid out the future membrane replacement rather than be locked into a specific membrane used in a proprietary system which has traditionally been the case.

OEMs qualified to bid are GE and Pall who have traditionally offered proprietary systems, and Wigen Water Technologies and H2O Innovation two of their fastest growing competitors who build systems using a number of different UF modules.

While there has been a lot of talk about Universal Racks in the past 12 months, this is the first bid I have seen that is based on this model. It will be very interesting to see how the 'Proprietary OEMs' fare against their more flexible competitors.

I will update with more project specifics when this is awarded.
