I

two professional engineers to assist in the preparation of the questions
submitted to the government authorities, and to review the information received.

An adjacent
wall, which did not collapse, was also sub-standard. That wall protected a
stairwell which the school relied upon for emergency escape purposes. This is a
matter to which I will return.

On morning
of Monday, September 21, 2014 the 500 students and their teachers were
permitted to enter their classrooms as usual. It seems, except for personnel of
the Department of Education and the Department of Transportation and Works (TW)
only the School Principal knew a major life-safety incident had occurred.

Response to the Blog Post
Public interest in the issue was huge. In addition, more than one person felt I had under-emphasized the risk to the workers who were closet to the site of the collapse.
The collapse
of a 50 feet high by 25 feet wide concrete wall, improperly constructed, and
lacking ties to the foundation, roof, and columns is a chillingly serious
oversight.
But, the workers are adults. Like one of
my informants, all could see the rubble on the ground; workers typically know who to call if
the work place is unsafe.

Readers may
recall that when the CBC reported on the Uncle Gnarley Blog Post, the story
contained this quote from Transportation and Works Minister, David Brazil:
“Maybe the communications could have been improved in a different directive,
but at the end of the day there was no issue around safety for those
students”. Elsewhere, the Minister stated the school and the construction
zone were separate.

The final
comment of the Deputy Minister is also revealing and of the school’s lack of readiness
for occupancy, on the morning of
September 22nd. Vivian-Walsh
states: “based on the investigation of the stairwell, it was not deemed
necessary to close the school. …mitigative measures….were completed overnight
on September 22 and 6:00 a.m. on the morning of September 23.”

The Deputy
Minister confirms the school’s fire escape was actually off-limits all day on
Monday, September 22nd.
In addition, if you review the email from Claude Foley of the Dept. of Education (p. 30) to various officials he says “Representatives of TW and the consultant(s) are onsite now for the check and to /or to determine extent and solutions.” His email is sent at 11:48 a.m. – half the school day is over.

Another
email….(dated Monday,
September 22, 2014 at 8.38 p.m.) from Baraco, the contractor, to Cory
Grandy states ”…the majority of the structural angles have been installed and
the work should be finished in an hour or so”. Grandy then sends an email to TW
staff saying: “Based on this we should be in good shape for tomorrow with
school business as usual”. (emphasis added)
But school business had been going on all that day!
It doesn’t
sound like that evacuation route was separate from the construction zone, does
it?
Consider this email from TW’s Jim Sinnott:

Consider this email from TW’s Jim Sinnott:
Note the words” “…as long as stairway accessible in the event of a real fire”.
But the officials provide no proof a competent professional assessed the “access” and declared it safe.
This email from Natalie Hallett (p.25) is also telling:
Obviously, “IF” repairs “will allow the stairwell to be open tomorrow” it must be closed today!
Now, let’s look at the email from Jim Sinnott, Facilities Manager, NLESD to Natalie Hallett ….a serious lack of communications is now heard:
Next, I want
to introduce a clip from comments made by Mr. Anthony Stack, Assistant Director
of Education (Operations) NLESD, who responded to some of the questions
contained in my ATTIP Submission. The full text of Stack’s remarks is found in NLESD’s ATTIP reply, found here. He says:
Two points on Stacks’ statement:
First, one of the two
engineers I asked to review the documents, from TW and NLESD, offered this comment:
this wasn’t a stairwell shut down because someone was painting. If the kids
kicked over a gallon of paint, in an emergency, who would care. But, the
stairwell was off limits, and not just because an inspection was being
conducted, as Stack asserts.
The second
point is that Mr. Stack seems not to understand the level of incompetence he
implicitly ascribes to the Department of TW.

The
Assistant Director mirrors assurances by the Deputy Minister of Education that the fire
escape is disconnected from the school but he also suggests “…reinforcement of
the wall was being added as an extra precaution…”

First, if a
wall, especially one of the size and weight under discussion, is viewed with
scepticism as to its structural integrity, no one should be permitted to go
near it until a structural engineer performs
an inspection (though “investigation” might be a better word).

Second, that
the wall of a school, no less, is given additional support “as an extra
precaution” confirms someone knew that that it was probably not constructed
according to engineering design specifications.

That implies

call it “loading”).

What Stack

Third, in
none of the correspondence received from TW’s ATTIP reply is there reference to the “Prime
Consultant”, the project Architect. The
Architect is the one knowledgeable of fire safety codes. This is not the structural engineer’s expertise. He should have been consulted regarding whether the school ought to be have been kept open.

Fourth, the first decision that ought to have
been made that Monday morning, apart from closing the school, was to suspend
the contractor. That would have been the correct “precaution” because the failure of a structural wall, for the reasons already noted, demands a review, by competent personnel, of its workmanship practices,
management personnel, and supervisory procedures. That TW permitted the very
same contractor not only to stay on the job, but to conduct repairs, in the absence of structural engineer’s inspection, constitutes a
gross error at the highest level.

In pursuit
of the answer, I asked TW (see complete TW ATTIP reply here) for structural Inspection Reports including testing information on the grout
used to load the cinder block walls, proof that the walls were dowelled
into the structure, evidence of the location and quantity of rebar used and of the masonry anchors and their connection to the structural steel, among other questions. (Readers will note that the ATTIP submissions were detailed; two professional engineers were key to the precision of those questions.)

2. DBA Site Inspection Report No. 1 was
dated Dec. 5, 2012. This Report was prepared at an early stage of construction
and dealt with formwork and reinforcements for the footings. It has no
direct relationship with the block wall construction.
But this report points out the contractor is sloppy and does not seem to understand the importance of some basic structural norms. The inspection suggests a good number of repairs are required. Having detailed the deficiencies, the expectation is the Structural Engineer might describe the method of repair. After the repairs are made, they would be inspected again. Neither record was provided by TW.

was not included with the documentation received then. While this Report graphically described poor workmanship and was a top off to the possibility of other structural
issues, the Report was prepared in relation to that singular incident. So, it is not relevant to the structural integrity of the other newly constructed
walls (though, as noted, it might have provided a clue).

But, first, I
should add this comment by one of the engineering advisors: when a contractor
“screws up” as evidenced by the rebar, plates, and other attachments missing
from the collapsed wall, the performance of the contractor enters a “show me” stage.
The Contractor is not believed until proof is shown, based upon inspections and a consistent pattern of good workmanship. In addition, what one expects is an increase in the number of inspections conducted
and an even greater diligent recording of the contractor’s adherence to the
design documents. Good workmanship is important. But the Owner (the Government) may need to dismiss the company – if the contractor displays a continuing lack of diligence. To do this, he should have incontrovertible proof that comes from diligent inspections.

design documents. Good workmanship is important. But the Owner (the Government) may need to dismiss the company – if the contractor displays a continuing lack of diligence. To do this, he should have incontrovertible proof that comes from diligent inspections.
That expectation
makes perfect sense. But, that is not what occurred. The Government provided gave no increased surveillance to the contractor’s work; in fact, there is practically
no information obtained through inspections, on which the Government or even the
Structural Engineer can rely.

An email
from Jim Sinnott of NLESD to various officials, dated September 1, 2015 is
especially relevant, as we get ready to consider the completeness of the
certification of the structural elements of the building.
Mr. Sinnott writes (p. 18 of Link) “…it is an accurate statement to say “all
walls at Roncalli Elementary have been inspected by a structural engineer”. The
engineer’s sign offs are project based vs. a wall by wall sign off, but the
statement is no less accurate”.

“Project based” is not a reassuring phrase, in this case. Sinnott will
have a tough time convincing the Structural Engineer he should take
responsibility for all those structural walls, especially when you
consider the caveat contained in his structural certification of the building.

Let me draw
your attention to the first paragraph on page 2 of the Structural Engineer’s
September 21, 2015 letter to the Department of Transportation and Works:
your attention to the first paragraph on page 2 of the Structural Engineer’s
September 21, 2015 letter to the Department of Transportation and Works:
This section of the DBA letter bears repeating: the structural engineer’s “opinion” is based on the structural integrity confirmed in site visits, reviews of testing, photographs, and inspection
reports “prepared by others”. He concludes the project is in “general
compliance” with the design documents …..
reports “prepared by others”. He concludes the project is in “general
compliance” with the design documents …..
Sinnott’s
expectation is not grounded in the Structural Engineer’s contractual
obligations to TW. It is, at best, wishful thinking.
But, given the lack of proof available by way of inspection, we need to ask: what does the structural engineer mean by
“general compliance”? What, exactly, is he certifying?

My ATTIP
application demanded the same information the Structural Engineer needs to base his opinion. Yet, only two site inspection reports were received
covering the concrete block wall construction phase – one, on the “mock up” wall was
practically irrelevant and the other contained a single photo showing a single piece of reabar.

If other Reports and tests were available, TW did not provide notice they were refused, under ATTIP rules. Therefore, I have to assume that no
other inspections or test results were conducted and, hence, not available.
How did the structural engineer assess whether the structural walls of the school are building code compliant? Where is the proof?

Finally – time to make a demand of the Provincial Government
A $20
million school expansion at Roncalli School:
Government failed to arrange the site inspections essential to quality control (its quality guarantee). The Structural Engineer’s “general compliance” certification is meaningless for those structural walls.
It can’t
call an Architect or insist on the immediate arrival of the structural
engineer. It can’t suspend a contractor.
But, it can allow 500 students and teachers to show up for school, even
if they don’t have access to a safe fire-exit.
Therein lies
the shame and the untold story (until now) of the Roncalli School Expansion
Project.
A completely independent and thorough third party inspection of the walls of Roncalli
School, using available methods, including intrusive procedures, to confirm they are constructed according to design specifications, is called for.

The parents
of kids at Roncalli should demand no less.

Response by Department of Transportation and Works to 2nd ATTIP Submission
Very disturbing. Nowhere is structural integrity more important than in an institutional setting where children must spend six hours a day. I look forward to a full engineering investigation to assure the safety of this entire structure. I assume that the professional society regulating professional engieers in this province has been informed of these revelations.

PEGNL to comment? Those guys should be involved. It would be interesting to know if they were even aware of the failure. In most jurisdictions there is a structural engineer of record who would be responsible for the construction as well. Not so in NL
Unfortunately the provincial government of this province looks at engineering as a commodity, one that they want to spend the least possible amount of money on. Engineers and architects now are typically selected based on the lowest price and not experience or capability. When you hire a lawyer do you shop around for the lowest hourly rate – no, you choose the one with the best relevant experience (that you can afford of course). Furthermore government wants to limit the amount of money spent on engineers and architects during construction as they feel they can do much of this work themselves in house. In this case the structural consultant likely did not perform adequate inspections as they were not paid to do so. At one time engineering and architecture where honourable professional professions, but not so today. It is often looked upon as a necessary evil and waste of money by those who want to bypass their use all together or limit their involvement to the minimum they can get away with.
