County failed to spot-check inspectors’ work as flaws developed at CityCenter
Sam Morris
The Harmon, center, was designed to rise to 49 floors, with condominiums built above the hotel floors. But the discovery of and attempts to fix a critical mistake in construction have CityCenter developer MGM Mirage deciding to scrap the condo part of the project.
Thursday, Jan. 15, 2009 | 2 a.m.
The Harmon tower at CityCenter will be 28 stories rather than the 49 originally planned.
Clark County’s Development Services Department has no record of its monitors ever visiting the Harmon construction project at CityCenter during the period last year when faulty rebar was installed in the tower, department officials said.
The county plans to make changes in the program that monitors private third-party construction site inspectors responsible for reviewing such work, and to begin an internal review of the system, Director of Development Services Ron Lynn said in an interview at his offices Wednesday.
“We do not have a record (the monitors) were physically walking the site,” Lynn said. “It doesn’t appear they were doing oversight at the level we would have liked.”
The eventual discovery of 15 floors of faulty rebar at The Harmon led MGM Mirage to announce last week that it would top off the building — originally planned as a 49-story tower — at 28 floors, canceling 200 planned condo units.
The incident puzzled Lynn and other experts, who couldn’t understand how general contractor Perini Building Co. and subcontractor Pacific Coast Steel could have installed the rebar with different mistakes throughout.
In some cases, the reinforcing steel was installed in the wrong locations inside beams, the county said. Some of the steel was so badly positioned it stuck out of the concrete floor and was sawed off to conceal the mistake.
Neither Perini nor Pacific Coast Steel responded to requests for comment.
The contractors are required by law to make sure the rebar is installed properly.
The incident has shed light on the Development Services program that monitors third-party inspectors — known as “special inspectors” — who are hired to provide constant oversight of complicated construction procedures to ensure structural integrity.
Begun in California to address earthquake-safety concerns, the use of such inspectors is standard in building departments across the country to make sure structures are not just designed but also constructed to properly hold up.
Building departments say it would be too unwieldy for governmental agencies to employ these inspectors themselves. Instead, project owners are required to hire them, and governmental agencies offer varying methods and levels of oversight.
Clark County has about 1,200 registered special inspectors who work for private agencies and must be approved by the county.
“They’re our eyes and ears,” Lynn said.
On paper, Clark County’s special inspector program is a model nationally — with tougher requirements of the privately hired inspectors and more scrutiny and specialized oversight than many other municipalities provide.
The county employs 12 “monitors” with the same type of specialized training as the special inspectors. The monitors review the private inspectors’ reports and issue violations to contractors for noncompliance detected by the private inspectors. The monitors are also supposed to spot-check the private inspectors to make sure they’re doing their jobs properly.
At The Harmon, the monitors did not appear to be fulfilling this responsibility.
The project’s engineer of record in July discovered that contractors had wrongly installed structural rebar on floors 6 to 15.
That discovery was made after the special inspectors hired by MGM Mirage had wrongly issued report after report to the county declaring the project in compliance.
The county-employed monitors directed to oversee those private inspectors didn’t file a single report indicating they were visiting The Harmon during this period.
Lynn and Manager of Engineering Theodore Droessler said they found this disturbing.
It could have been a paperwork mix-up, Lynn said: The county moved to a new database system last year to track employee time and these workers at CityCenter did not enter logs into the system, he said.
But the monitors also did not file reports marking that they received clearance of each floor from the private inspectors, as would have been expected, Lynn and Droessler noted.
“It’s usually a good time for the inspector to make an entry, to say that they physically encountered acceptable construction,” Droessler said. “There weren’t any entries in this case.”
Lynn and Droessler said they’re concerned the county employees may not have been visiting The Harmon. That could have been due to the overwhelming scope of their duties monitoring the entire $9.2 billion CityCenter project, where seven buildings have risen simultaneously, they said.
One county worker was stationed full time at CityCenter while another was working part time at CityCenter and part time at Echelon, another massive project that was halted in August amid the recession.
It appears the county monitors were reviewing the reports from the private inspectors without spot-checking the work, Lynn and Droessler said.
“Could they have caught this? The answer is yes,” Droessler said. “But the focus for the monitors has been on reviewing the daily reports from the special inspectors and paying particular attention to noncompliance.”
Lynn has since instructed monitors to more vigorously spot-check private inspectors to make sure they are acting properly. He is also adding several monitor positions and plans to place two additional workers at CityCenter for a total of four county monitors on the project.
“Since the incident, we’ve been asked to be on the projects and do more direct verification of some actual construction work, to actually look at some of the construction compared to the drawings,” Droessler said. “That activity was pretty light. We would get out on the projects where we knew there were problems.”
The county is currently wrapping up an investigation of the two special inspectors at The Harmon as well as of Converse Consultants, the agency that employed them. It could lift approval of the employees or the agency if it finds they acted improperly.
Converse Consultants representatives did not respond to phone calls.
Lynn said it appears the two Converse inspectors at The Harmon have not worked on any other sites in the county.
After work is done on that investigation, Lynn said, he plans to begin an internal review of the department’s oversight at The Harmon.
County commissioners said they plan to ask questions of Lynn regarding the program. Several said they had never heard of the special inspection procedure until last week.
“I think this raises questions about the purview of the private inspectors — what their job is, how it is being done, what standards they are held to and why it didn’t work,” Commissioner Steve Sisolak said. “This is a public safety issue and the integrity of these buildings is a major concern. I want some more answers.”
Commissioner Chris Giunchigliani said she plans to raise concerns at the meeting on construction workplace safety she is convening at the end of the month.
“We should know what we expect from the monitors,” Giunchigliani said. “Is it just paper-pushing or are they on site? Do we have enough checks and balances?”

To actually get some of the County Building inspectors out of the job site trailer or off the ground level would be a good start.
There are good county inspectors that do their jobs well, but there are some that don't look at the work in progress and that applies to the third party inspectors as well.
They hang out in the job trailers or their trucks and just sign off the inspections without even looking at the work. Refer to the Kessler International Audit of Clark Co. Building Department dated March 11, 2008 ... oh, but you can't, it isn't on the county's website anymore.
I was a building super for a General Co. for four years. It was shocking what the subs would try to get away with. People working who did not speak English constructing walls that they should not have benn working on, drywall installers not following the approved standard to screw the drywall to the metal studs, etc. I think the only subs that did their work correctly the first time were the carpet installers.
Color me naive, but, isn't there some kind of standard to be followed on inspections? Aren't they supposed to occur at specified intervals with specified criteria on specified elements of the project?
It seems to me, assuming this was not an "intentional" act on somebody's part, that there are some massive holes in the system here. That this was caught "after the fact" is the real story.
It also seems to me that this is one of the most massive projects taking place on the planet right now. $10 billion? Wow, that's huge. Maybe we should be careful and pay attention to what we're doing? Anyone?
It's simple. The County hires third party inspectors to cover the County's ass. There is no way Clark County would hire the amount of legitimate inspectors needed to perform the work, since this would put responsibilities on their supervisors. Actually, it is good that they don't hire directly-this would create more pension dependent, lifelong layabouts working for the county. And if you want to see the results of government gone wild, check out the inspectors with the City of Henderson-they now have no work, so the city is hiding them in the Redevelopment Department, picking their noses.
Response to johnevegas:
Yes, there are "standards" to be followed by inspectors.
The International Building Code, which is the Code adopted by Clark Co. Building Department, has the requirements clearly laid out as to what is supposed to be inspected and if it is to be continuously or periodically inspected.
There is also the Clark County Administrative Code which governs this and states the inspectors are to follow the Clark Co. Technical Guidelines.
And when it comes to the discipline the special inspector is inspecting, there are specific codes, specifications and standards they are to inspect to.
To give one example in this instance, the inspectors should have been following the documents listed above and the "Building Code Requirements for Structural Concrete, ACI 318-05 from the American Concrete Institute in addition to the approved structural drawings.
From all that has been printed so far about the issues at the Harmon and Veer towers, if the accounts are totally accurate, then it is very clear the special inspectors did not comply with Clark Co. Technical Guidelines, Administrative Code, the International Building Code, the ACI 318 and the approved structural drawings.
What has not been talked about yet, is where was Converse Consultants Quality Assurance Manager during all this? The QA Manger is responsible for insuring their inspectors have the proper training, are qualified and are complying with the building department requirements, Codes, Standards, and internal requirements.
A lot of failures and holes in this project seem to have happened.
Perini has their own Quality Control Inspectors... where were they during the construction? It appears this is another checks and balance that either was not in place on this project or was just on paper. What does this all say about the quality of construction in the other buildings constructed by Perini at City Center or for that matter in the rest of the County by Perini?
With the current economy, fire Ron Lynn and the inspectors that failed to do their job. We dont need them and I am sure that there will be lawsuits aganst the contractor, the inspection company and the county.
"What does this all say about the quality of construction in the other buildings constructed by Perini at City Center or for that matter in the rest of the County by Perini?"
Exactly. My next question was along those same lines.
When a liar lies, it calls into question everything else they say. A pattern is a pattern, yes? So it is less likely that their other projects are different and more likely that they are the same. That really concerns me.
The County monitors that were reviewing the reports from the private inspectors without spot checking the work should IMMEDIATELY be terminated. There was no record of the monitors walking the site???? Why Not????? And why didn't Ron Lynn or any of the other people in The Development Services Department REALIZE as the building was being built that there were no records of County inspections on 15 floors of a building???? Is everyone sleeping???
What does this say about the workers who ignored design specs and general accepted industry standards when they did very poor rebar work?
I would hope that this places a red flag on those workers and the supervisors of those workers.
Obviously, union workers does not mean automatic quality work.
Why do we require union wages for school construction work? Obviously, these union workers have disproved the theory that union workers equals quality work.
Of course, the inspection company has a giant red flag on its doors. Its reputation is zero now and probably will face a big lawsuit.
House of cards.....
Of course, our cowardly DA David Roger will not file criminal charges against anyone over this, because it is casino-related. Another Harrah's-type cover-up. Shameful and disgusting.

So typical to hire some unlicensed, unqualified worker (most likely illegal to boot) just to save a buck. When will the people in this country wake up and realize some things are more important than just saving a few bucks - like giving jobs to Americans who know what they're doing?
I do wonder, considering the the current placement of the re-bar, if the building is up to the required structural code?
If it cannot meet code, should the structure come down? Who has the authority to make this decision?
If twenty years from now, we have loss of life due caused by these defects, who will be held liable for these known problems? The State and the taxpayers? The owners? The Construction Company? The Engineering Firm?
An inquiring mind would like to know.
good ol' nance. Always there to blame the unions. And, by extension of course, the unionized worker.
Of course, the union worker is not blame. They just ignored what they were told to do and ignored years of standard rebar installation princples. Sloppy rebar work???? Of course not....
That is my fault. You can blame me.
re:azsk8fan
most of the work was inspected by legal american workers.your comments only show how much of an idiot you are.look into something before commenting.
My two cents:
1. Jobs like this one run on The Almighty Schedule. When the General Contractor schedules 600 yards of concrete to start arriving on site at 10pm on Thursday night, then 600 yards of concrete starts rolling out of the batch plant at 9pm on Thursday night. A little thing like the reinforcing steel being wrong or incomplete does not stop the pour.
2. It is unprofessional and unseemly for a building official to name names and point fingers. There are proper venues to assess blame, the front page of the Las Vegas Sun is NOT it. Especially when the Building Department was supposed to be providing oversight on the project, and wasn't.
3. With the amount of money involved, this is almost certainly going to become a legal matter. Nobody had any right to name the General Contractor, the Sub-Contractor, the Consulting Firm, or the Special Inspector's names in a newspaper article.
I work in the industry, and am sure as hell glad I don't do it in Las Vegas.
To b dover: If I was a simple man I would just tell you to suck my dick. But, since I'm not, let's discuss this. The Clark County Building Dept. doesn't hire Special Inspectors, dumbass, the Permitee does. I thought you would know that, due to your "extensive" knowlege of this subject. You speak of various municipalities. Which inspector did you piss off. You need to understand what a Special Inspector is, thence, understand when they are required. Then, understand the amount of training and verification (by those municipalities) that goes into becoming an ACCEPTED Special Inspector. If, out of all of us, one or two falls through the cracks, never, AND I MEAN NEVER, make reference to the CCBD using illegitimate inspectors; to protect your life. You have a serious chip on your shoulder and should get rid of it. Or else you will cause a road rage accident, or be a wife batterer, you a-hole. By the way, nothing is simple; except you.
I have nothing else so say, so don't comment back; and nobody either, please.
"I have nothing else so say, so don't comment back; and nobody either, please."
President Bush? Is that you?
As a Structural Engineer here is some perspective, the building code gets more complex, why? to make the buildings safer and or economical. The design engineer generates a design who's quality varies by engineer, FOR A FEE, that design is reviewed by the building department, FOR A FEE, that varies by reviewer. Then the building gets built by a builder who is trying to save as much money as possible and the building department is inspecting the work, FOR A FEE. The only one in this process that is not subject to a law suit is the City's Building Department (BD) and that is clearly announced by every employee when things start going wrong. So who is supplying the safety net in these type of projects, the BD has neither the money, time, training or interest to perform this service. The public thinks the BD is providing this service, an answer is to have the professional engineer who is already responsibile and liable perform this task. The professional engineer who designed the building best understands what is most important in the construction and what to look at and look for. Have the inspectors work for the engineer, not the owners or contractors and have then responsible to the engineer and require the owners to pay the engineer. Fees to the BD are most often currently used as a revenue source for the general fund, and instead of the owner paying the BD to provide the safety net, have the owner pay the engineer provide it.
It is all about the appearance. If the county or city wants to appear like they are monitoring the special inspection agencies, all they have to do is monitor the books. Third party special inspection agencies are a conflict of interest. If the owner hires a special inspection agency that doesn't "work with the GC" the special inspection agency will probably not get hired again. The owner hires the general contractor and in the interest of having the job run smooth the owner will ask the GC which agency is good. So the owner will usually go with who the GC wants. The GC only cares about the schedule and special inspectors often get bullied into not writting an NCR and if there are no NCR's written the job appears to be perfect (no such thing). Unless you have auditors looking for jobs with no NCR's and looking at the plans , the reports and the actual work being performed there is no way to know what is being covered up. There are many buildings that are largely deviated from the plans in this town. No one wants to know they all want deniability. Unfortunately, it will probably take a disaster and people getting injured before anyone wants to really know how these buildings go up. Been there seen it, no one wants to know.
Has anybody brought up the concern that if the Harmon was "defective", couldn't the other construction at the CityCenter also be defective? Is the same contractor building the other towers?

To CARP:
Your "knowledge" of the building construction and inspection process is mistifying. "Third party special inspection agencies are a conflict of interest." Really? There are many checks and balances written into the International Building Code to avoid conflicts of interest. Code requires the owner (not contractor) to hire a Special Inspector. The Special Inspector is approved by the Building Official and works as a consultant to the owner to observe and document the contractor's work for compliance with Code. (A conflict may arise if the contractor hires the Special Inspector, since the contractor could ignore the inspector or choose not to pay them if they don't like what the inspector says or does.) Code also requires that the Special inspector provide daily reports to the owner, engineer, and contractor so that the observations, including non-compliance issues are communicated and addressed promptly. In most cases, correction notices are initially communicated verbally during progress of construction prior to critical points (i.e. placement of concrete). Most contractors prefer the opportunity to correct mistakes as they go. If not corrected, then a written notice of non-compliance is issued.
In many areas, there are also requirements for the design professional (structural engineer or architect) to provide structural observation at specific times during construction to confirm that the work meets intent of the design.
However, the buck stops with the Building Official. They are required to have building inspectors visit the site regularly during construction to observe, review documents, talk to the Special Inspector, etc. In most cases this is done daily. On a job this size, I find it shocking that Clark County would provide only 1 full-time and 1 part-time inspector to oversee the Special Inspectors.
If what is written about the defects is true, I find it hard to believe that the Special Inspectors that wrote reports stating that everything was to Code actually observed what they reported. If the quality of the work was as bad as reported, even a rookie inspector would have noticed. But they would actually have to be there to see it.
In my opinion, there appear to be several problems leading to breakdown of communication: project is understaffed by inspectors, contractor and subs desperate to stick to the schedule at all costs, lack of observation by design engineer, and poor review and observation by the Building Official. All parties will point the finger at someone else, but none will escape culpability.
