Building 01, houses the majority of classrooms, administration, cafeteria, kitchen and ancillary functions; and three smaller buildings, numbered 02, 03 and 04, are connected to the main building through a 10’-0” covered walkway. These smaller buildings house additional classrooms, storage and maintenance functions. Building 01 is a 39-year-old masonry structure with a galvanized metal roof and an insulated acoustical drop ceiling. The roof over this building is in reasonably good condition while the roof over the walkways is corroded and leaks in several areas. The guttering system is mainly 6” aluminum in fairly good condition but not anchored firmly; it leaks at many joints and in many cases is not securely attached to its base or the downspouts. The main building’s walkway roof is supported by C-channel framing with metal sheathing; all supported on 3”x3” steel posts at 25’-0” on center. The general scope of the work shall include: repairing a small canopy that connects Building 02 with the main building, repairs to structural purlins and support columns, prepping and coating top and underside of flat walkway roofs, cleaning, caulking and anchoring loose guttering, and replacing rotting soffit and fascia and rehanging sections of sagging suspended ceiling in classrooms. Work also includes replacement of the Cistern-Overflow at Building 01 and reconnecting to existing drainage system, pressure testing for leaks, and repair of leaks, if found. If ground disturbance is required for repair, then the Historic Preservation Office will be contacted and agreement reached prior to repair work.

Minor Concrete Spail Repairs Description Most minor concrete spalls are repaired using neat Type VIII epoxy (no sand) to help protect against deterioration caused by exposure to the water, chlorides, and other contaminants. Minor spalls can be built up using Type VIII epoxy mortar. Generally building up minor spalls with mortar provides no additional corrosion protection or capacity vs. neat epoxy only. Filling the voids removes the appearance of spalling and is typically done based on aesthetic concerns. Submittals Prior to the start of work, the Contractor must provide construction details reviewed and approved/ stamped by a licensed structural engineer (hereafter referred to as “the Engineer”), for all areas of work. Details must include a determination of 1) whether the damage is surface or structural, 2) select an appropriate method of repair, 3) select suitable materials, and 4) specify quantities of work to be performed. 2o0f9 Attachment 5 - Outline Specifications INVITATION FOR BID — Attachment 5 Outline Specifications Ricardo Richards Elementary School Roofing & Cistern Overflow Repairs Material Tx.DOT Type VIII neat epoxy compound (ASTM C 881 Type | or IV) is produced by mixing two proprietary liquid components in the ratio required by the manufacturer. * Refer to OMS 6100, OMS 6110, and the MPL for Epoxies and Adhesives for additional information. * Use materials from Tx.DOT's preapproved list for Type VIII epoxy. Contractor may use other materials only if specifically authorized by the Engineer in writing. Tx.DOT Type VIII epoxy mortar is produced by combining the neat epoxy compound and an aggregate (usually silica sand) approved by the epoxy producer and Tx.DOT. * Ratio by Volume: * Adhere to the requirements from the manufacturers’ technical data sheets when proportioning the sand to add to the neat epoxy. * — If using Industrial Coatings as the supplier for Type VII! epoxy, proportion the mortar at 1-part neat epoxy to 5 parts sand. The epoxy-to-sand ratios are typically lower for the other approved suppliers, in the range of 1-part epoxy to 1.5 to 2 parts sand. * Silica Sand: * Most manufacturers recommend that 20/40 mesh sand be used to produce epoxy mortar. It is acceptable to use sand that passes a No. 16 sieve but is retained by a No. 50 sieve (16/50 mesh). * Use sand other than 16/50 mesh or 20/40 mesh only if authorized by the epoxy manufacturer and the Engineer. * — If the patch will remain visible after a member has been erected, the Engineer may require use of a combination of gray and white sand to make the epoxy mortar material closely resemble the surrounding concrete. Do not exceed 130°F if heating any of the epoxy liquid components to ease mixing or application. If using sand from a stockpile, ensure that it has been properly dried and graded before mixing. Sand should not stay clumped together after being bunched up in a fist. NOTE: It is a good idea to keep a separate container that is protected from rain and other water for storing sand used to mix Type VIII epoxy mortar. Sand from 30f9 Attachment 5 - Outline Specifications INVITATION FOR BID — Attachment 5 Outline Specifications Ricardo Richards Elementary School Roofing & Cistern Overflow Repairs a stockpile is typically far too wet to be used for mixing epoxy mortar. Do not exceed 230°F when heating sand to dry it. Allow sand to coolto a maximum temperature of 130°F before mixing with the neat epoxy. Repair Procedure Surface preparation is important. Refer to Attachment 4: Minor Patch Repair Details 1D and 1E for a graphical description of preparation and repair procedures. * Surface preparation. * Remove any damaged or loose concrete. * Avoid damage to sound concrete that is to remain in place by saw cutting the perimeter of the patch area or taking other appropriate measures acceptable to the Engineer. * Unless otherwise approved by the Engineer, use only hand tools or power-driven chipping hammers (15-Ib. class maximum) to remove concrete. * — If the damage occurs at the end of a member and pre-stressing strand is exposed, recess the strands a minimum 3/8-inch using a torch or other approved method. Do not overheat or damage the surrounding concrete. NOTE: In the past some Contractors and Fabricators opted not to recess pre- stressing strands in spalled areas so the protruding sections could serve as dowels for the patch material. While the strands would serve well as dowels in those circumstances, they could be exposed to moisture and chlorides if the patch fails over the life of the structure. For that reason, it is more important that the strand be completely recessed. * Ensure substrates are clean and sound. Remove any contaminants, including laitance, oil, dust, debris, or other foreign particles. * Just prior to coating or patching, blast the repair area using a high- pressure air compressor equipped with filters to remove all oil from the compressed air. * For minor spalls in which a short longitudinal section (less than 4") of mild reinforcement or pre-stressing strand is exposed, the steel should NOT be removed. Nor should sound material behind the steel be excavated unless more than half the bar circumference is exposed, in which case the spall should be classified as Intermediate. * It is not necessary to install dowels or provide other mechanical anchorage in applications less than 1 %” thick. The Engineer may require dowels, typically stainless steel expansion anchors, in thicker applications to help tie the patch to the parent material in case of a delamination. 4o0f9 Attachment 5 - Outline Specifications INVITATION FOR BID — Attachment 5 Qutline Specifications Ricardo Richards Elementary School Roofing & Cistern Overflow Repairs * Mixing. Measure the proper quantity of each component per the manufacturer's requirements, then dispense into a clean container. Do not estimate the proper amounts while adding the different components. Mix the liquid components thoroughly using a low-speed electric drill (400 - 600 rpm) and a clean "Jiffy" type mixing paddle. Do not mix Type VIII neat epoxy or epoxy mortar by hand. * — If utilizing whole batches, mix the liquid components for a minimum of 3 minutes or in accordance with the manufacturer's instructions. * — If using partial batches, mix for at least 1 minute or until the material is well-blended and uniform, whichever is longer. Slowly add the sand or other approved aggregate to the epoxy compound while mixing with an electric drill and paddle. Mix the material until the epoxy mortar is well-blended and all sand particles are coated (1-minute minimum after the sand is added). Mix an adequate amount of additional neat epoxy compound for use as a waterproofing and bonding layer. Set times vary significantly depending on type of epoxy and ambient conditions (temperature, wind, humidity). In hot weather (greater than 90°F) place a partial batch in a cup to determine set-up time, and adjust production volumes accordingly. * Neat Epoxy Application. * Surface must be dry and clean prior to application of the repair material. * Brush, roll, or scrub the material into the prepared substrate to ensure that all small voids are filled. * Cover the entire damaged area, including exposed steel reinforcement and dowels when applicable, with at least 10 MILLs of the neat epoxy compound. NOTE: Members of the repair crew should have a wet-film thickness gauge to periodically check that neat epoxy is being installed in adequate application depth. Inspectors should also carry wet-film thickness gauges so they can verify adequate minimum thickness. * Epoxy Mortar Application. * Apply a layer of neat epoxy compound to the substrate as outlined above to serve as a bond coat layer for the repair mortar. 5of9 Attachment 5 - Outline Specifications INVITATION FOR BID — Attachment 5 Outline Specifications Ricardo Richards Elementary School Roofing & Cistern Overflow Repairs * Trowel-apply the epoxy mortar into the repair area while the bonding layer is still tacky. If the bonding layer loses its tackiness prior to patching, clean the epoxy surface and apply additional neat epoxy before proceeding. * — Limit repair depth to 1 inch when using epoxy mortar unless otherwise approved by the Engineer. In multiple lift applications wait until previous lift has cured sufficiently to pre- vent sagging prior to applying the next lift. Apply a bonding layer of neat epoxy between each lift. * Finishing. The Contractor should consult the Engineer before patching minor spalls in which an aesthetic treatment will later be applied. As noted above, the Engineer may require that white or gray sand be used to produce epoxy mortar if a patch will remain visible in its final configuration. Such patches should not be easily discernible if viewed from more than 25 feet away. The Engineer will review other methods proposed for blending patches. * Curing. The required time for the material to cure properly can increase significantly when the ambient temperature is below approximately 50°F. If artificial means are used to heat the in-situ neat epoxy or epoxy mortar, ensure that the air around the repair material does not exceed 130°F. Moist curing is not required, Commentary The high bond strength of properly mixed and applied Type VIII epoxy mortar makes it a good option for use in thin applications where inclusion of dowels is not practical and excavation behind partially exposed steel would unnecessarily necessitate removal of sound material. Do not use Type Vill epoxy mortar for structural patches or in other areas where significant movement from loading or temperature variations are anticipated. Stress caused by differential movement at the bond line can develop because the coefficient of thermal expansion of Type VIII epoxy mortar varies significantly from the concrete substrate. This can apply even in thin applications if the damage covers a large area. 6o0f9 Attachment 5 - Outline Specifications INVITATION FOR BID — Attachment 5 Outline Specifications Ricardo Richards Elementary School Roofing & Cistern Overflow Repairs 05 Division: Metals SECTION 51200: Structural Cast Steel Components Part 1 General Replace portions of metal framing, where a flange web or other component has lost more than 10% of its original cross section.
