vs. ) CASE NO. 84-1920
Respondent. )
Consistent with the Notice of Hearing furnished the parties as modified by the Order Granting Continuance dated November 27, 1984, a hearing was held in this case before Arnold H. Pollock, a Hearing Officer with the Division of Administrative Hearings, at Patrick Air Force Base, Florida on December 14, 1984. The issue for consideration was whether Respondent's license as a professional engineer in Florida should be disciplined because of the alleged negligence in the practice of engineering as outlined in the Administrative Complaint filed herein.
For Petitioner: Carol L. Gregg, Esquire
By Administrative Complaint signed by the Secretary of the Department of Professional Regulation on October 12, 1983, Petitioner alleges professional misconduct on the part of the Respondent and seeks to discipline his license as a registered professional engineer in the State of Florida. On May 17, 1984, the Respondent, Raymond E. Hirst, Jr., filed an amended election of rights form in which he disputed the allegations contained in the Administrative Complaint and requested a formal hearing.
At the hearing, the parties together introduced Joint Exhibits 1 through 10 and Respondent introduced Respondent's Exhibit A. Petitioner introduced Petitioner's Composite Exhibit 1. With the concurrence of both parties, the Hearing Officer took official recognition of the Brevard County Building
Regulations, a copy of the minutes of the City of Palm Bay regular council meeting number 83-5 held on March 3, 1983, a copy of Chapter 21H-19, Florida Administrative Code, a copy of Section 103.6 and 105.3 of the Southern Standard Building Code.
In addition, Petitioner presented the testimony of Paul A. Olsen, Chief Building Official for the City of Palm Bay; James O. Power, a registered structural engineer from Miami, Florida; and Ernest C. Driver, also a consultant engineer licensed in Florida. Respondent testified in his own behalf.
Petitioner has submitted posthearing proposed findings of fact pursuant to Section 12O.57(1)(b)4, Florida Statutes. A ruling on each proposed finding of fact has been made either directly or indirectly in this Recommended Order, except where such proposed findings of fact have been rejected as subordinate, cumulative, immaterial, or unnecessary.
At all times pertinent to the issues herein, the Respondent, Raymond E. Hirst, Jr., professional engineer, was licensed as such by the State of Florida under license number PE 0017307.
Prior to March 22, 1983, the Respondent, for Mech-Mar Engineering Company, Inc., designed a storage bay and mini- warehouse project to be built by Ruth Stein Construction for William M. Kwasniki, to be located on South Babcock Street in Palm Bay, Florida. Petitioner designed the facility and signed the plans for construction on March 22, 1983. A note clearly marked on the sheet index on the upper right hand corner of the first page of the plan set reflects, "The engineer's services do not include supervision of the construction of this project."
The plans consist of three sheets of drawings, each of which is sealed and signed by the Respondent. The first sheet reflects the foundation plan.
The second shows the electrical riser and firewall detail, and the third reflects the elevations. On or about April 3, 1983, the contractor, Ruth Stein, submitted these plans to the City of Palm Bay building department. The plans were approved for construction by the office of the chief building official, Paul Olsen, and formed the basis for the issuance of the construction permit.
Neither the engineer's specifications nor calculations were submitted and filed with the plans. However, calculations were not required by the City of Palm Bay at that time. Two amendments to the plans were filed by the Respondent on May 31, and August 10, 1983. No revised drawings were submitted, however.
The drawings that were submitted by Ms. Stein, but drawn by Respondent, were used to insure that the plans conformed to standard building codes, zoning codes, etc., but were not reviewed by the city for compliance with engineering standards and no engineering analysis was done by the city on these or any other plans at that time. The need to do so was apparently recognized later, however, as such analyses are now done on a routine basis. The plans were also to be used by the city's inspection staff to compare work being done by the contractor with the plans to insure that the work conforms to them.
During construction, the building being erected according to Respondent's plans, a concrete block structure, collapsed. This collapse occurred sometime prior to May 20, 1983.
After the structure collapsed, the city building office again approved the plans drawn by Respondent for reconstruction. The contractor was told to clean up the site and was then allowed to rebuild. Not only the original plans but the amendments referred to above, including that dated August 10, 1983, called for partitions within the building.
After rebuilding, the structure was inspected by the city and a certificate of occupancy was issued in August, 1983. No complaints have been filed regarding this construction since that time. After the collapse, an inspection of the collapse site revealed that in some areas on the west part of the structure, cells of the concrete blocks being used to form the walls had not been filled with concrete as was required by the design submitted by Respondent. In the opinion of Mr. Olsen, this defect was a fault not of the Respondent but of the contractor.
No determination was made by the city as to:
whether the block walls as designed by Respondent met Standard Building Code (SBC) requirements;
whether the walls were supported laterally as required;
whether anchorage of the roof trusses to the walls was accomplished;
whether Respondent properly, or at all, designed a roof diaphragm for this project;
whether the walls were adequate to meet the wind load requirements (the SBC suggests that maximum wind velocity standard is 90 mph.);
whether the lentils were adequate; and
whether the truss anchorage limits were satisfactory. (According to Mr. Olsen, this decision is left up to the engineer who designs the structure.)
The city found, however, that a part of the reason for the collapse of this structure was that the trusses for the roof were set too soon, were not adequately braced, contained questionable materials, and wore questionably fabricated.
Though the city was not critical in its analysis of Respondent's performance, the experts retained by Petitioner to evaluate his drawings were. Mr. James O. Power, who has been a registered structural engineer since 1947 did not examine the building site but is aware of the project in question. He reviewed the drawings prepared by Respondent, photos taken of the site, the investigative report, letters and correspondence from Respondent with calculations contained therein, and the Respondent's amendments to the original drawings. On the basis of this evidence, he formed an opinion as to Respondent's performance as an engineer on this project and prepared several letters on the subject dated July 6 and October 21, 1983, and January 30 and September 7, 1984, all of which constitute his opinion as to Respondent's performance. In substance he concluded that Respondent's engineering performance on this project was unsatisfactory showing basic negligence and lack of due care as well as a lack of understanding of the basic engineering requirements for the job.
In his opinion, overall, the drawings lack sufficient detail. For example, they, (a) show no interior partitions (partitions were defined in an amendment to the drawing filed after the collapse); (b) show that while the southern wall has few openings, the north wall has many, (this is significant in that because of the lack of partitions, the walls must resist the winds playing upon them as vertical cantilevers); (c) show that the number 5 vertical bars in the fill cells are 12 feet apart, (to serve as reinforced masonry, they should be 4 but no more than 8 feet apart depending on the circumstances); (d) reflect a ceiling height of 14 feet whereas later drawings show a difference in elevation; (e) show that the tie beam is to be constituted of inverted masonry
U-beam 16 inches deep filled with concrete and reinforcing steel without providing for any obvious way to insert the concrete within the beam; (f) failed to show with detail the strap makeup or method of connection for the hurricane straps to be used to hold down the roof trusses to the walls, (the drawings show that the strap is to loop over the truss and if the straps do not do so, the connection is weak); (g) reflect that the door height at the openings on the north and south side doors are different than the tie beam height but there is no showing of how the weight of the roof is to be distributed over the door head only 8 inches below the tie-beam (this could contribute to the collapse of the building); and (h) failed to show drawings of trusses by the Respondent. In this regard, the truss company's drawings and specifications are insufficient.
Since the Respondent's drawings do not define with particularity how the trusses are to be constructed, the truss fabricator must make assumptions as to the stress and load to be applied.
With regard to the pre-engineered and pre-manufactured roof trusses, Mr. Power is of the opinion that the designer, Respondent, should have: (1) stated his criteria for the design of the truss (Respondent did not do this);
(2) stated the qualifications of the designer (Respondent did not do this); (3) submitted clear instructions regarding his design (Respondent's are unclear and unsatisfactory). Mr. Power also indicates that in his experience, bracing for the trusses is installed at the building site and that only the basic truss is constructed at the truss company's plant. Respondent, on the other hand, contends that the practice in Brevard County is for the building designer, as here, to give the basic specifications needed for the truss, and thereafter, the truss designer, working for the truss company, designs and builds the complete truss for delivery to the site. If Mr. Power's position is to be believed, personal supervision of the designer would be required at the site once the basic truss was delivered. Here, however, Mr. Power operates out of Miami and Petitioner has failed to show that he is familiar with the trade practice in the area involved in this dispute. Respondent's position is somewhat supported by the fact that his plans contain a disclaimer of supervision and no issue was made that this is a forbidden or unaccepted practice. Consequently, it cannot be said that Respondent's design of the trusses in this case was faulty.
Mr. Power also identified several "design deficiencies" in Respondent's work. Among these were that there was no requirement for the use of reinforced masonry which is different from concrete and that Respondent's drawings provided no details or standards for the mortar or grout, the substance used to fill the holes in concrete blocks which should have a minimum slump of 8 inches. (If one tried to fill these cells from the top of a 14 foot wall, it is most likely that the cell, the hole within the blocks, would not be filled.) Further, the formulae used by Respondent in his calculations are for solid
materials in the walls -- not for cinder block which was the material called for here. On the basis of the above discrepancies, it appeared to Mr. Power that Respondent did not understand the difference between the requirements for construction with concrete block and those for construction with reinforced masonry.
In addition, according to Mr. Power, the reinforcing walls inserted in the design by the Respondent after the collapse of the building are of materials not permitted by the SBC. Also the SBC requires that the ratio of length to width of roof diaphragm should be no more than 4. The purpose of this is to provide support to the top of the wall so as to resist loads placed upon it by the force of wind. Here, Respondent's design has not adequately provided this reinforcement, in Mr. Power's judgment, and the design does not meet the SBC requirement.
The SBC also requires designs of buildings to be constructed in the Palm Bay area to be able to withstand 90 mph winds. Mr. Power's calculations based on Respondent's plans and drawings show it is questionable that a building built pursuant to Respondent's plans would sustain 90 mph winds. The fact that the chances are only one in fifty that in any given year winds of this speed would be reached is immaterial.
As to the filling of the holes (cells) in the concrete block, Mr. Power contends that it is a good practice to show in the drawing a breakout in the block at the bottom of the wall so that the builder can see that the concrete has in fact gone all the way down to the bottom as it should. Here, however, the building code does not require this to be done. Again, considering the Respondent's use of cement instead of grout to fill the cells, the Respondent followed county practice and the SBC does not specifically require the use of grout. Nonetheless, Mr. Power is of the opinion that even though Respondent's drawings indicated that he would not inspect at the site, it was unreasonable for Respondent to expect the cells to be filled since it is well known that many contractors do not inspect to insure that the cells are filled as called for. Mr. Power is also of the opinion that the lintels as described in one of the amendments to the basic drawings, though permissible for use, are inadequate to handle the indicated roof load and the drawings prepared by Respondent did not show the lintel capacity.
Mr. Power contends that the SBC requires drawings to show sufficient detail to indicate the intent of the designer to allow the contractor using the drawings to conform to code standards. Admittedly, this is subjective criteria, not an objective one, as to what constitutes sufficient detail. The amendments added to the original designs helped somewhat to correct the deficiencies, but do not make them adequate. Taken as a whole, the drawings are not adequate, in the opinion of Mr. Power, to comply with the SBC. They are not adequate to pass on the designer's intent to the contractor and they are not adequate to show the designer's understanding of design elements. These errors and deficiencies described above are, in the opinion of Mr. Power, significant and not minor. Based on his analysis of the overall drawings and situation, he concluded that Respondent has not demonstrated his capability to handle this particular task which, in the opinion of Mr. power, is relatively simple.
Respondent's drawings and the other documents pertinent to the project in issue here including calculations, correspondence, photos, and the investigative report, were also reviewed by Ernest C. Driver, a Florida licensed consultant engineer operating in Cairo, Georgia. Mr. Driver also reviewed Mr. Power's reports and is in complete agreement with his conclusions.
He did some calculations on his own and on the basis of them, formed an opinion of Respondent's performance as an engineer on this project. He found that the reinforcing of the cinder block cells on the walls were too widely spaced at 12 foot centers instead of 4 to 8 foot centers. In addition, he did not agree with the engineering conclusions drawn by the Respondent. The calculations performed by Respondent were, in his opinion, improper and as a result, the design is over-stressed by approximately 215 percent. This came about, apparently, because Respondent designed a wall as though there were no doors in it. In addition, the way the tie beam is designed, it is impossible to get the reinforcing concrete into the "U." Further, the hurricane straps required to affix the roof trusses to the tie beam cannot be attached to the beam itself. Also, the design called for concrete block to be installed above the doors. This procedure placed as much as four times the load the lintel should carry.
Mr. Driver also found that the diaphragm used by Respondent was of gypsum board which, in his opinion, is not a proper material for diaphragms. Also, according to Mr. Driver's interpretation of Respondent's plan, there is no way that the wind shear force applied to the diaphragm can be transmitted to the side wall and thence down to the earth. This is a definite deficiency and Respondent's drawings and notes are not complete enough to allow a clear determination of what is required as to materials to be used and how the work should be accomplished.
Other deficiencies are seen in that the drawings show a 230 foot long building without an expansion joint. In Mr. Driver's opinion, this is far too long for construction without such a joint. In addition, the 26 foot high end wall is not addressed in the design which has no indication of how the roof is to be attached to it.
Mr. Driver concurs with Mr. Power's opinion regarding the insufficiency of the plans and specifications offered by Respondent for the roof trusses in that there is no framing plan nor are there specifications identified for the trusses. Shop drawings should have been provided instead of only a cut sheet. While this witness does not know what the current Brevard County practice regarding the design and construction of trusses is, he is convinced that it is as Respondent says it is, to wit: that they are completely fabricated at the shop and delivered completed for installation to the job site, this is a poor practice. Connected to the issue of roof trusses is that regarding the metal hurricane straps which Respondent indicated his plans called for. These metal straps, which can easily be bent by hand are, in the opinion of Mr. Driver, a poor method of affixing the trusses to the tie beam. There are too many things that can go wrong such as hinging, the lack of a firm seating for the strap in the concrete, the bending of the metal, and the pulling of the affixing nails through the holes in the strap thereby resulting in no grip.
In addition to his dissatisfaction with the use of concrete to fill the cells in the cinder blocks, Mr. Driver also feels that the use of concrete to fill a continuous 14 foot cell is improper. In his opinion, the drawings should call for a solid block every 4 feet and for weep holes through which compaction can be noted periodically throughout that distance. All of this should be in the engineer's notes. The notes by Respondent do not identify these areas. Even though Respondent's notes called for the 14 feet to be filled, his plans failed to provide methods to insure that complete filling was accomplished. Examination of the pictures of the wall after the collapse reveals that complete filling was not accomplished and this failure on the part
of Respondent to provide a reasonably foolproof method of insuring complete compaction cannot be excused and responsibility shifted to the contractor by the mere statement by Respondent on the plans that he would not inspect.
Engineering practice is made up of judgment as well as the specific formulae which can be obtained from engineering textbooks. There are assumptions which may be made -- some good and some bad. In the opinion of Mr. Driver, the defects described above indicate that Respondent's assumptions were bad. As a result, his judgment was bad. He feels that, in light of all the evidence, Respondent was negligent, failed to use due care, failed to conform to accepted engineering principles, failed to accomplish drawings sufficiently detailed to instruct the contractor as to exactly what needed to he done, and failed to provide drawings which, if followed exactly as presented, would by themselves, enable a builder to construct a safe structure. Here, based on the drawings prepared and submitted by Respondent, a builder would have to demonstrate a high and exceptional degree of expertise in order to fill in the omitted details required to make the building safe.
Acceptable drawing standards are not defined with specificity in the SBC. Much is subjective rather than objective. For example, nothing in the SBC prohibits the use of gypsum board as a horizontal diaphragm, but, in the opinion of Mr. Driver, it is not common practice to use it for such. This goes to the question of judgment. In any event, the code may be erroneous in some particulars and not all answers are contained in it. It is for this reason that the law requires the use of a licensed engineer whose judgment fills in the gaps left by the code.
Here all the defects identified in Respondent's drawings are within the province of an engineer. These are the items an engineer is needed for to accomplish. Here, in the opinion of Mr. Driver, there are too many defects and Respondent's work does not conform to any of the standards used in the engineering community as to schooling, information gained from working with other engineers, or the witness's personal experience.
In rebuttal to the above, Respondent presented no experts of his own, but testified as to his disagreement with the analyses of Petitioner's experts. The testimony by Mr. Power and Mr. Driver is found to be accurate and descriptive of the defects in Respondent's performance. There are a few exceptions such as where local Brevard County practice differs from the experience of these experts, however, taken as a whole, the evidence clearly indicates Respondent's shortcomings for the most part. The testimony of the experts has established a series of defects in Respondent's performance which he has failed to satisfactorily rebut.
CONCLUSIONS OF LAW
The Division of Administrative Hearings has jurisdiction over the parties and the subject matter of these proceedings.
Petitioner has charged the Respondent with a violation of Section 471.033(1)(g), Florida Statutes and being guilty of negligence in the practice of engineering in that he failed to utilize due care in performing in an engineering capacity or failed to have due regard for acceptable standards of engineering principles as defined in Rule 21H-19.01(3), Florida Administrative Code.
The Administrative Complaint outlines a myriad of allegations regarding specific instances in the design of the building in question where Respondent is alleged to have demonstrated this negligence. Along these are several alleged violations of the SBC.
The evidence presented by the Petitioner, unrebutted by Respondent in any way save his testimonial disagreement with the opinions of Petitioner's experts, clearly establishes that for the most part Respondent's performance was seriously flawed here. Even giving Respondent the benefit of the doubt in those areas where local practice in Brevard County differs from the experience of the experts, and even accepting that the provisions of the SBC are not sacrosanct, there nonetheless remain sufficient examples of Respondent's design deficiencies to establish that, overall, he failed to have due regard for acceptable standards of engineering principles. His drawings, in ailing to depict to the contractor clearly what his intentions were for the construction of the building in question, clearly establish his negligence.
Because these design failures were not the sole cause of the collapse of the construction in question but were merely one factor in the overall picture, and in light of the fact that this is the first indication of Respondent's failure to perform properly, neither revocation nor suspension of his license is appropriate.
Based on the foregoing Findings Of Fact and Conclusions of Law, it is, therefore:
RECOMMENDED that Respondent, RAYMOND HIRST, be placed on probation for one year, that he be reprimanded, and that he pay an administrative fine of $500.00.
RECOMMENDED this 19th day of February, 1985 in Tallahassee, Florida.
