Add water in amounts cont)atible with convenience in using mortar. If mortar begins to stiffen from evaporation or absorption of a part of mixing water, retent)er by adding water and remix. Grout shall have a slun~) of 10-1/2 to 11 inch at time of placement. Mortar and grout shall be used within 2-1/2 hours of initial mixing and no mortar or grout shall be used after it has begun to set. PART THREE - EXECUTION 3.1 PROTECTION OF WORK Ae Do not proceed with masonry construction, until permitted, when the following foundation tolerances are not met: Horizontal alignment (Variation from plan dimension) +1/4" in 10' 1/2" max. variation Vertical alignment (Variation from level) +1/4" in 10 ' 1/2" max. variation Be Cold weather: When temperature is below 40 degrees F. and falling, or forecast to occur within 48 hours, provide fireproof protective covering of work and heat materials using Underwriters' Laboratories approved flame heaters. Maintain materials and work above 50 degrees F. for 72 hours. Do not use any admixtures to prevent freezing. Do not lay frozen materials or build on frozen surfaces. Lay masonry units dry. Ce Compressive strength of masonry shall~be required in the project documents. Make masonry prism tests at Masonry Subcontractor's expense. Do not start masonry construction until masonry prism 04210-4 5-86/JJR 14303 SECTION 04210 MASONRY WALLS tests show required compressive strength of masonry can be obtained. If any prism tests do not meet required compressive strengths stop masonry construction until Owner has been notified of test failures. Brace or otherwise protect walls during erection as required to protect work from dama§e. 3.2 PLACING MASONRY UNITS Ae Construct masonry plumb, true to line, with level courses built to height, thickness and running bond pattern. Use masonry units that are sound, dry, clean and free from ice and frost when placed. Be Adjust each unit to final position in wall while mortar is still soft and plastic. Remove any unit disturbed after mortar has stiffened and relay with fresh mortar. C. Use masonry saws for cutting and fitting of masonry. D. Mortar bedding and joints: 1. Soak facebrick units prior to laying. J Place hollow units with full mortar bedment in all courses of columns and where adjacent to cells or cavities to be reinforced or filled with grout. In other cases provide cross web bedding when required. o Place hollow units with head joints tightly mortar for a minimum depth from each face equal to the unit face shell thickness. bedded masonry e Place face brick and other solid units with full head and bed joints. Bed joints shall be furrowed. e Make horizontal and vertical face joints 1/2" thick unless otherwise required. Shove vertical mortar joints tight. t Tool mortar joints concave in all exposed masonry surfaces with joiner, when thumbprint hard. J Remove mortar protrusions extending more than 1/2" into cells or cavities to be grouted. e Rake joints and tool smooth and uniform to a depth of 3/4", unless otherwise required or accepted. Seal joints as indicated on drawings. 04210-5 5-86/JJR 14303 SECTION 04210 MASONRY WALLS In temperatures exceeding 100 degrees F., do not lay out mortar beds ahead of placing units. Use a very light fog spray, not sufficient to penetrate the masonry on a vertical surface of masonry to aid in mortar curing during the first 24 hours after placing units. 3.3 CONTROL JOINTS Ae Provide control joints as shown in drawings and construct by using special control joint units and control joint fillers. Reference Section 07950 for sealant material. 3.4 CUTTING AND FITTING Ae Cutting and fitting shall be done by masonry mechanics. Wherever possible, use full units of proper size in lieu of cut units. Openings shall be carefully cut, formed, or otherwise neatly made for recessed items and for electrical installations so that wall plates, cover plates or escutcheons required by the installation will completely conceal openings and will have bottoms in alignment with lower edge of masonry joints. 3.5 REINFORCING BARS 3.6 Ae Hold vertical bars in position at top and bottom and at intervals as indicated on drawings with a minimum clearance of one-quarter inch from the masonry and not less than one bar diameter between bars. When a fountain dowel is not in alignment with a vertical block cell or pilaster, slope it not more than one horizontal in six vertical to bring it into proper alignment before grouting. GROUTING Ae General: Fully grout vertical cells of concrete masonry containing steel reinforcement. Wherever possible, grouting shall be done from inside face of masonry. Exercise extreme care to prevent grout from staining face of masonry. Immediately remove grout spillages on face and top of masonry. B. Low lift grouting: Assure that grout core is clean of mortar and drippings and other deleterious material. e Grout spaces less than 2" width, at intervals of not more than 24" in lifts of 6" to 8" as wall is built. o Grout spaces more than 2" in width in lifts not to exceed 2'-0" as wall is built. 04210-6 5-86/JJR 14303 SECTION 04210 MASONRY WALLS 4. Agitate or puddle grout during and after placement to insure cont~lete filling. Stop grout 1-1/2" below top of masonry when grouting is to be stopped for one hour or more. 6. Continue grouting to top of finished wall. 7. Refer to drawings for locations of grout. High lift grouting: At Contractor's option, high lift grouting may be used where grout space is 2" or more in width. Insure that walls have sufficient joint reinforcement or ties to prevent displacement during grouting. 2. Keep grout core clean from mortar and droppings. e Provide cleanout holes by omitting one brick in bottom course on rear side of column. Prior to closing cleanout holes and pouring grout use high-pressure jet stream of water or high-pressure air to remove excess mortar from grout space and to clean reinforcement. Do not plug cleanout holes until condition of area to be grouted has been accepted. e Before pouring grout, plug cleanout holes with masonry units and brace against grout pressure. Grout spaces 2" or more in width in lifts not exceeding 4'. Extent of a single pour shall not exceed 25' in length nor 12' in height. Time period between grout pours shall not be less than 1/2 hour nor more than i hour. Be Vibrate or agitate grout during and after placement to insure complete filling of grout space. Stop grout 1-1/2" below top of masonry when grouting is to be stopped for one hour or more. 3.7 ADJUSTMENT AND CLEANING A. Adjustment: Replace masonry work which does not match sample. Cleaning: Wipe all excess mortar as work progresses. Dry brush at the end of each day's work. After mortar is thoroughly set and cured, clean masonry surfaces with proprietary cleaners specified in conformance with manufacturer's recommendations. 04210-7 5-86/JJR 14303 SECTION 04210 MASONRY WALLS 3.8 Ce Remove rubbish, debris, dirt, equipment, and excess material from the site.

The purpose of this investigation was to provide design recommendations for free standing wa]is along MacArthur and Parkway Boulevards. No additional analyses were requested or performed. This report is being submitted in summary form. Descriptions and details of the various field and laboratory tests are on file in our office and may be obtained upon request. The results of the field and laboratory tests are shown on the individual boring logs submitted herewith. SUMMARY: The project site is located in the City of Coppell within the Lakes of Coppell Development, Current plans indicate that brick walls will be constructed along the north and the south sides of MacArthur and Parkway Boulevards at the locations indicated on the enclosed Plan. e The generalized subsurface profile revealed by the test borings consisted of gray, brown, reddish brown and yellowish brown days, sandy clays, clayey sands and sands. The primary gray shale stratum 23,12 Fabcns PO. Box 59902 [)alia,,~, Texas 75229 (21,1) 247-7575 Mr. William Cobb July 11, 1985 Page 2 was encountered at depths ranging between 1.0 and 11.0 feet below the existing ground surface except in test borings B-1 and B-2 where the shale was not encountered during the drilling operations. Seepage water was encountered in test borings B-6, B-7 and B-12 at 5.0, 7.0 and 7.0 feet below the existing ground surface, respec- tively. However this condition may change with seasonal climatic conditions and should be verified prior to construction. The structural loads of the proposed wall may be supported by one of the following foundation systems: Auger excavated, cast-in-place, straight shaft reinforced con- crete piers founded at least two feet into the primary gray shale layer if the shale is encountered at a depth of less than 12 feet below the existing ground surface. The piers may be designed using an allowable bearing pressure of 10,000 pounds per square foot. In areas where the shale is not encountered within the top 12 feet (area of borings B-1 and B-2), the piers may be underreamed twalve (12) feet below the ground surface. An allowable end bearing pressure of 2,400 pounds per square foot may be used. The pier shafts should contain enough steel reinforcement to resist tension forces of up to 1,000 pounds per square foot acting in a vertical direction that may be created by the swel- ling of the surficial overburden softs. Foundation piers, proportioned, designed and placed in accordance with the recom- mendations provided in this report will have a factor of safety in excess of 2.0 against shear type failure. Differential settlement between adjacent piers should be less than 0.5 of an inch; or Individual or continuous footings founded approximately two (2) feet below the ground surface within the clay, sandy clay, clayey sand and sand softs and designed using an allowable soft bearing pressure of 2,300 pounds per square foot. Care should be taken to insure that the footings excavations are free of loose material prior to the placement of the concrete. The walls or grade beams should be designed to withstand differen- tial vertical soft movement of up to 2.00 inches caused by the swel- ling of the near surface softs, or should be provided with a void space between the exposed subgrade soils and the wall/grade beam structure where foundation piers are used.
