A Day in the Life of a Civil Engineer – Day 70

Day 70

GIS Group Meeting

Today started out amazing then in the afternoon went to total frustration. I had to leave very early this morning to meet a co-worker for a GIS meeting of IMAUG – Illinois Municipal Arc Users Group. If you are into GIS, this is a great group to get involved with. Today's meeting was in Vernon Hills so pretty far away from Geneva where we work. But it was well worth going to. I was scheduled to speak first thing about QR Codes. Not sure it was a subject many were interested in, but hopefully I was able to offer some insight into their use in our industry. Below this post is the presentation I gave.

The other presentations were much more amazing! Will Rockwell from the village of Vernon Hills explained to us how to use Google Fusion tables and maps to make incredible GIS maps. Wow – they turned out great looking with very little work. Here is a link to more information from Google about using this tool: http://www.google.com/fusiontables/Home/

We also heard from a few other speakers who talked about applications for checking properties with liens, ESRI certifications, and a county web map service.

Parking Lot Project

After lunch and after we returned, I went with a couple other engineers to meet with a few people to discuss the design of the alley that will connect our proposed parking lot with one of the main streets through our downtown. This was a good meeting, and we look forward to getting a landscape design from the person we met with.

Water Main Project

My primary frustration hit when one of the engineers gave me a copy of the easement plats we had arranged to have prepared for our water main project. We had purposely hired a local firm to provide the surveying services because they have always produced such good work for us in the past. Imagine my surprise when the engineer gave me the plat and said, "we have a problem – they left off part of the property." Sure enough they had missed the fact that the property owner had acquired additional property over which our easement should have run. And as the engineer pointed out, the surveyor had actually shifted our easement over from where we had shown it to be because of missing this additional parcel. Well, when I looked at who prepared the plat, it was not the firm we had hired but another that we had specifically chosen not to use exactly because of problems like this. So I called the firm we had hired to ask why they hired another firm to do the work we hired them to do. All they said was sometimes they do that. No apology – no "I guess we should have asked if we could sub out the work." Nothing. I am not even quite sure how to respond at this time because I have never even heard of a firm doing such a thing. We are supposed to meet on Monday to discuss where to go from here.

A Day in the Life of a Civil Engineer – Days 68 & 69

Days 68 & 69

After spending most of the day yesterday in meetings, getting home late, then having to run out to attend a band concert, I decided just to wait until today and post both yesterday and today in one article. So here it is!

Tuesday:

IDOT audit of ARRA project

IDOT was scheduled to be in this morning to audit my paperwork for the last ARRA project the city completed in 2010. They, along with the FHWA, have already looked everything over several times and have always been very helpful. They were scheduled to be here at 9 so I had made plans to be out of the office the rest of the day after 11 thinking two hours would be enough time, but they ended up not being able to get here until after 10:30. So I couldn't be here while they were going through everything. And because I am still waiting for the last authorization to be approved, I couldn't really finish all the paperwork, so they will have to come back anyway one more time. I guess at least this way, I can be here next time so in case they can't find the information they need in my records, I can find it for them.

APWA – Detention Pond Design

The rest of the day was spent attending a talk by the APWA about detention areas. Someone from a suburb in the Chicago area shared their experiences with building natural ponds. They said in the early 1990s a lot of mistakes were made in building these facilities, and now there's a lot of maintenance and performance issues. Many have just turned into a huge pile of weeds needing a lot of work. Their community has been systematically renovating the ponds to improve their functions. And she said they are working now to avoid any problems with new ponds that are proposed by developers.

She brought up a lot of interesting and helpful tips about pond design. One included making sure an ecologist checks the seed list. She said they have seed lists submitted that contain weeds and seeds for plants that do not grow well by seed.

APWA – Communications

The other meeting I had was with our chapter communication committee. We were set up at the last executive committee meeting to look into the communications of our chapter. This was our kick-off meeting where we looked at the big picture of what we were trying to accomplish and who we were targeting as an audience. Then we decided what methods and tools we were going to research. I have been creating a workbook for us to use in this effort. So when we are done, I will post a copy of the workbook on the site so anyone else can use it for similar efforts.

Wednesday

Lighting of our Parking Lot

We are still having issues with finding lights that meet the photometric requirements for our parking lot. The last vendor I was working with could not find a light, and like our consultant, did not want to alter our parking lot configuration to make it work. So I contacted one last vendor and asked if he could find a lighting scheme that worked even if it meant changing our parking layout. Hopefully he will be able to come up with something. If not, I don't think we'll be able to meet the lighting requirements for spill over.

Staff meeting

We also had our staff meeting today. Like we do at most, we discussed all our projects. And at the end we tried something new where we held a pre-design project meeting. At this meeting we discussed next year's road project and how we wanted to approach the plan development. We also set some tentative milestones and dates.

Subdivision meeting

Later in the afternoon we met with representatives of a subdivision that is going through a possible change in ownership. The subdivision was never completed, and we are trying to work to get the public improvements done.

Miscellaneous

There were a few other miscellaneous projects I worked on such as helping a resident complete documents to vacate a portion of the city alley. And I am still waiting to get that bid tab from PACE. It has been such a busy week, and tomorrow is also looking like its another full day!

Day 67

Culvert Lining Project

I didn't have a chance to go out to the culvert lining project myself today because I had too many other meetings and things to do. But a couple of my staff went out to watch the contractor pour the headwalls. Our concern over this operation has been that the subcontractor chose to completely block the culvert to perform this operation. The project engineer made it very clear to him that he was doing so at his own risk. Today, after the pour, they cut an opening in the form, but from what I was told, it still doesn't open it up to its full capacity. Although there was little threat of a heavy rain last night, a lot more rainfall is predicted for Tuesday, so the contractor needs to get in there immediately in the morning and remove the form and cut out the supports inside the pipe.

Southeast Plan

We've been working with a consultant on a plan of how the area lying south and east of our community will develop. According to boundary agreements with the other cities in this area, the land is anticipated to be annexed to our city. It's somewhat of a challenging location due to some natural topography and roadway and utility connections. So our city chose to undertake an overall planning effort to determine the best development scenario. By doing this, it's easier for developers to more quickly assess any issues that would affect proposed improvements in this area.

So today we met with the consultant to determine the plan's current status and how we want to proceed.

Downtown Planning

I spent the afternoon in another meeting with staff and the consultant who is working on our downtown plan. We explained to him the changes and comments we had on his draft plan.

Day 66

Culvert Lining Project

It looks like our issue with the culvert lining project has been resolved. We gave the structural drawings from our consultant to the contractor. Theh contractor ended up getting a couple prices from other concrete contractors which were lower than the original subcontractor's price. So it looks like we will end up getting the work we needed done at the price that was bid. It rained today so the contractor did not work, but he should be back out tomorrow to form the head walls.

Road Project

We've started on the plans for next year's road project. Today, I worked on adding a few more roads, My supervisor had said we could try increasing the amount we normally spend since we are not keeping up with the failure rate. Of course, all this will be subject to the approval of the council. We are just going to suggest this amount. We did get a little extra in MFT funds this year so that amount could be applied to this project.

The PACE sidewalk project

Today I tried to get a copy of the bid tab for the PACE project I discussed yesterday. The person I emailed said I had to submit a FOIA request to get it and that I had to ask how to do this by emailing their law department. Well, we have been through the FOIA drill here, and from we've been told, someone can ask for something on a dirty napkin, and that is an acceptable request to which you must respond. We can no longer require anyone to go through a formal process to get something. So because I did not hear back from the law department, I tried emailing their FOIA officer directly. He read the email but did not respond, so I'll have to see if they end up sending it or not. We did ask a local contractor who bids that type of work if they put in a bid, and they had not even been aware the project was out to bid.

Water Main Project

I met with the property owner of one of the parcels where we are asking for an easement for our water main. They said we could go ahead and submit the documents for their signature. I also worked a little more on the modeling but realized I needed the pump curve for our high service pumps at the water plant. So I arranged to have them sent over.

Tomorrow I am scheduled to be out of the office so won't be writing "A Day in the Life.." post for Friday.

A Day in the Life of a Civil Engineer – Day 65

Day 65

I really wanted to title this blog post:

Today I Discovered Why We Have no Transportation Funds!

The other day, I wrote about the BRT and Randall Road -  the major corridor that runs through many of the communities in our area. In that post, I also mentioned the Route 529 study – this was a study about the bus route running along the Randall Road corridor. One of the conclusions from the study was that there needed to be better infrastructure along the corridor for the people riding the bus. And if you drive the corridor, you'll see this is definitely the case. The bus stops are only marked by a lonely sign sitting at the edge of a roadway where about 20,000 cars a day speed by at 45 miles per hour. So a rider must get off in that environment, find their way across a ditch and then through landscaping to a shopping center. So a project was proposed to construct bus shelters, pads, and connecting sidewalks. 

Chicago

PACE, the local entity providing bus transit in the Chicago Metro area, arranged to bid out a project to construct the suggested infrastructure. Now, I don't know all the details of this project, but according to the PACE website the project is listed as Bid #406453 and shows a cost of almost $1.4 million that was awarded to Landmark Contractors, Inc. In our area, along Randall, PACE was proposing to build the shelters, pads, and sidewalks not only on the side of the road the shelter is on, but to also build the connecting ramps and sidewalks at the other corners in the intersection nearest the shelter. We had all reviewed the plans over the last few months to make sure we had no issues with what was going to be constructed in each of our communities. So today, we were invited to a preconstruction meeting for the project. The contractor, Landmark Contractors was at the meeting along with a person from PACE, the project designer, county staff, and city engineers from a few of the cities along the corridor.

Now I've been to a lot of preconstruction meetings over the years, and this one most definitely did not end up to be your typical precon. However, it started out fairly typical – there was a discussion of how the concrete would be protected from the effects of the salt once winter weather set in. This was a valid concern because over the last few years, beginning about Dec 1st, we've had temperatures drop to well below freezing and had significant snow and ice. And that is only a few weeks away. I won't bore you with the discussion, but the bottom line was that there really is no way to adequately protect the concrete this late in the game. So the discussion moved onto "shouldn't we wait until Spring to start?"

And this is where it started to get strange. Because a few of the people had just shown up at this point (we had started early), the group moved on to tell us that they were cutting back the plans to only do what was required of them to meet the ADA. This meant they would only build the infrastructure on the same side of the road as the shelter leaving no route across or on the other side of the intersection. It was explained they had to do this because the bid prices came in so many hundreds of thousands of dollars more than what they expected that they could not afford to build what was on the plans. Now this is where I started thinking something was wrong – it was basically a sidewalk project  - how in the world could the bid come in that much higher? Particularly at a time when we are seeing the lowest prices ever on construction work? The other engineers in the room must have been thinking the same way based on their questions. I finally suggested that if the costs per square foot were so much higher, why didn't they just let each city build it for them as part of the MFT projects, and they could pay us the grant money. When I had said this, I really wasn't sure of the bid price they had received, so another person at the table pushed the list of bid prices over to me. I wanted to stand up and yell, OMG!!! Wow, they were paying $8.26 per square foot for PCC Sidewalk! Now, I don't know what the rest of you across the world pay, but we normally pay anywhere from $4.50 to $5.50. And I've even seen it lower if we are doing a lot of it. And in this case, PACE was proposing building 39,000 square feet! For that amount, in this economic climate, they definitely should have gotten a better price.

And the other unit prices were no better! It looked like $175 per cubic yard for earth excavation and about $47+ per foot for curb and gutter. Again, the engineers in the room, including myself, could not help but call attention to the prices. The contractor said they were so high because he had to deal with the cold weather including the use of blankets and overtime costs. Someone else pointed out that he was the low bidder and that PACE had followed all the proper bidding procedures – I guess that was supposed to mean that the prices had to be ok. The contractor did suggest that if the work was held off until Spring the prices would be a lot lower. But what was also strange was that he said he could lower the unit prices as part of the contract. I figured if he lowered them to what is normally bid, he would be cutting them in half. But normally when you award a contract with unit prices, you can't just change them. There's a process, and the adjustment is usually only about 10%. So we couldn't figure out how they could legally do this without re-bidding the project. Which was something we suggested – wait until Spring and take the time to re-bid.

There was some discussion that PACE was worried about waiting because the Federal grant money for this project could be pulled at any time so I guess PACE has to quickly spend it to avoid losing it. The PACE person made it sound like the Federal government arbitrarily swoops in and takes the money even if they are already under contract for a project and obligated for the funds. Finally someone suggested that after the plans were stripped to only what was required, the remaining work removed from the contract could be completed by others, and for a much lower cost than the bid. But the problem here was there was a chance the cities would be asked to pay for a portion of this. I did mention that I would have a hard time advocating for our city to help pay for any of the improvements that were removed if the reason they were removed was because the bids PACE accepted were significantly higher than costs normally bid.

By the end of the meeting, I was thinking that I can't imagine a city awarding a bid like this. If bids come in significantly high it's usually a problem with material or contractor availability or a problem with the plans. And in this case, it did not appear to be any of these. So the only conclusion I could come to was that PACE must have had no problem awarding a bid that included prices that were about twice the cost of bids other agencies would receive for the same type of work. It was all so very strange and did not make sense that I figured I was either totally naive and did not understand how transit agencies and funding sources from agencies like the FTA really work, or I was totally missing something, or as I said above: I discovered why we have no transportation funds! But no matter what, I figured if they do reauthorize transportation funds, they really need to write into the law a way to prevent agencies from awarding bids in situations like this when the bids are significantly higher than the estimated cost and obviously not reflective of the market conditions.

After all that, anything else that happened throughout the day faded into the background.

A Day in the Life of a Civil Engineer – Day 64

Day 64

Culvert Lining Project

Today was somewhat of a continuation of the issues that started yesterday with our culvert project. Tomorrow I am meeting with the contractor and giving him the detailed structural design that we received today from our consultant. The contractor will have to determine if the work shown was what he anticipated when he bid the job. If not, he will tell us how much more he would charge us. Then if this is the case, we will need to review the increased amount and decide if we think that is a correct value. If not, and if we cannot reach an agreement, we will have to remove the concrete work from the contract. 

This is a good lesson in why it is so important to have a lot of detail in the plans. A misinterpretation of the plans by the contractor or a difference in interpretation from what was expected by the engineer can lead to problems like this during construction. It can also lead to higher bid prices if there had been some uncertaintly on the contractor's part about the work when he was determining his bid. It's frustrating for us because we are managing the construction, but had to rely on another engineer for the design and the plans. And I realize it's frustrating for the contractor. Now we have a real chance of having to delete the work from the contract because the plans/specs seemed to have caused a difference of opinion over what the work entailed, and we are not sure if we can come to some agreement on the cost.

Water modeling

I have been working on the design of a water main extension. Today I contacted one of the owners of a parcel over which we are asking for an easement. We arranged to meet later this week to look over the area. I also started working on running an analysis of the water system with this line in place so I can finish filling out the IEPA permit. Fortunately a model was built several years ago when the city built a new water treatment plant. And the consultant who built that shared the information with us. It was built with EPANET so I downloaded the program. In the past I've used a DOS -based program and WaterGems, but since the data is in the EPANET format, I will just try to figure  that software.

Miscellaneous & NaNoWriMo

We also drove a few more roads to determine their condition. Then at the end of the day, I attended an APWA education committee meeting. Today was also the beginning of NaNoWriMo. It's not really an engineering event, but I've always enjoyed writing so have tried to participate most years. And it's a great incentive for working on writing skills. I encourage anyone interested in writing to check it out!
