Ocean Drive,Jensen Beach,FL 34957 Contractor: DMF Construction 312 S. Old Dixie Hwy. Jupiter,FL 33458 Background: The removal and restoration of deteriorated concrete and steel within beams, columns, decks and adjacent walls will comply with the IRCI Guideline No. 03730 (a copy of which is attached hereto) or as modified by Engineer as work progresses. The anticipated work involves the initial demolition, and then the removal, replacement and restoration of concrete and reinforcement as required. The degree of restoration is currently unknown,until such time as the initial demolition has begun. The anticipated sequence of repairs is as follows: • Shoring required for repairs of all columns,beams and decks (if required by engineer) • Removal and restoration of concrete and reinforcement steel within beams, columns and decks. (ICRI Guideline No. 03 73 0) • Minor chipping and patching of areas not requiring full depth repairs. • Applied deck coating. The following materials are approved for anticipated use in this restoration(see attached manufacturers specifications): • Sikacrete 211 Concrete Mix. • SikaQuick 1000. • Sika Armatec 110 EpoCem bonding agent and rebar coating. • Sika FerroGard 903. • Sikagard 701W. FILE COPY • SikaTop 123 PLUS. • TREMCO Vulkem® 350NF 1 2431 SE Dixie Highway OWN Stuart, FL 34996 Phone: (772)287-0525 MATHERS ENGINEERING EB#004456 CORPORATION See enclosed plan showing location of restoration. The above sequence is general in nature and will be modified as restoration work progresses. Observations of the initial demolition will determine any required modifications to the above procedures and materials selected for the final restoration process. Based on initial visual observations, repairs will not require shoring;however, in the event the demolition work reveals that shoring will be required,the engineer will instruct the contractor to shore the area as well as the number of levels required. The instructions given to the contractor will be submitted to the Building Department with the final close-out documents. We have been authorized by the Association to work with the contractor during the restoration and, will inspect work partially completed as well as observe results of the new demolition prior to field authorizing the repairs to be completed. The proposed concrete restoration work, except as authorized by the engineer's modified instructions,will comply with specifications outlined in the IRCI Guideline No. 03730, as well as the applicable minimum building codes and the applicable fire safety standards as determined by the local authority in accordance with Chapter 553 and Chapter 633 of the Florida Statutes where applicable to concrete restoration.

Add additional water up to 1 gallon total. Mix to a uniform consistency, maximum 3 minutes. Mechanically mixwith a low-speed drill(400-600 rpm)and paddle or in appropriate size mortar �YG mixer or concrete mixer. �r Application Form and pour or pump applications:Pre-wet surface to SSD. Ensure good intimate con- tact with the substrate is achieved.To accomplish this,material should be scrubbed into the I 'r� tr substrate or other suitable means should be employed such as vibration of the material or pumping under pressure.Vibrate form while pouring or pumping. Pump with a variable pres- sure pump. Continue pumping until a 3 to 5 psi increase in normal line pressure is evident >ry then STOP pumping.Form should not deflect.Ventto be capped when steady flow is evident, and forms stripped when appropriate. Z- Tooling&finishing As per ACl recommendations for portland cement concrete, curing is required. Moist cure �1. with wet burlap and polyethylene, a fine mist of water or a water based*compatible curing compound. Curing compounds adversely affect the adhesion of following layers of mortar, s leveling mortar or protective coatings.Moist curing should commence immediately after fin- k"{+� ishing. Protect newly applied material from direct sunlight,wind, rain and frost. *Pretesting of curing compound is recommended. r�r afi t,�n w,Wp€zr..a�7a Limitations ■ Application thickness: Minimum 1 in. (25 mm); Maximum 8 in. (200 mm) ■ Minimum ambient and surface temperatures 45°F(7°C)and rising at time of application. ■ Using SikaLatex®, SikaLatex®R or similar products will result in loss of slump and slump retention.

Pat Winkler,Chair* The identification,development,andpromotion of the most promising methods and materials are Dan Anagnos primary vehicles for accelerating advances in Randy Beard repair technology, Working through a variety of Bruce Collins forums, ICRI members have the opportunity to William"Bud"Earley address these issues and to directly contribute to Peter Emmons* improving the practice of concrete repair. Andrew Fulkerson A principal component of this effort is to make Randy Glover carefully selected information on important repair Fred Goodwin* subjects readily accessible to decision makers. Kurt Gottinger During the past several decades, much has been Tyson Herman reported in the literature on concrete repair Dave Homerding methods and materials as theyhave been developed Bob Johnson and refined Nevertheless, it has been difficult to David Karins find critically reviewed information on the state of Ken Lozen* the art condensed into easy-to-use formats.
