July 31, 1995 c. Eugene Buth, P.E. Consulting Engineer P. o. Box 27 Wellborn, Texas 77881 ., SUPPLEMENT TO LIMITED REHABILITATION OF PARKING FACILITIES AT PARK PLACE PLAZA COLLEGE STATION, TEXAS This supplement describes proposed limited improvements to drainage facilities at Park Place Plaza Shopping Center on Southwest Parkway in College Station, Texas. SCOPE: Proposed work is limited to construction of two small surface inlets and 12-inch diameter pipe connecting the two inlets to existing storm sewer. Background information is given in the original report. PROPOSED WORK: Pavement distress and ponding of water exists in Basin No. 2 shown on Exhibit Two of the Galindo drainage report. This area is marked on Exhibit A and shown in the photograph in Exhibit B attached hereto. This basin does not drain completely because it was constructed with very small slopes and the pavement has moved vertically. It is proposed that two small surface inlets be installed at now existing low points and connected to the existing 33-inch diameter storm sewer pipe as shown in Exhibit C attached hereto. At its junction with the 33-inch diameter pipe, the flowline at the 12-inch diameter pipe is set at an elevation of 271.30 ft. and the flowline of the 33-inch pipe is at elevation 270.42 ft. Flow in the 12-inch pipe will be restricted when the 1 1.. •• 33-inch pipe is flowing near full. At peak storage, head on the two proposed surface inlets in Basin No. 2 will be approximately 0.4 ft. Open area for each grate (Neenah R-4441) is 0.2 sq. ft. The computed discharge through each grate is: Q = CA../2gfi Q = 0 • 7 ( • 2 ) v'2 (3 2 • 2 ) ( • 4 ) Q =O.?lcfs Total discharge for two inlets would be 2 x 0.71 = 1.42 cfs. Total discharge from the three proposed surface inlets (one in Basin No. 1 and two in Basin No. 2) will be not more than 1.20 cfs for Basin No. 1 plus 1.42 for Basin No. 2 or a total of 2.62 cfs. Total existing discharge in the two 48-inch diameter pipes leaving Park Place Plaza is stated to be 252 cfs in the Drainage Report for Park Place Subdivision dated May 14, 1984. The increase in discharge rate resulting from installation of the three proposed inlets would be 2.62 + 252 = 1.04 percent. 2 ......... 3: 0 0:: 0 IO ........ >- <{ 3: :..:: 0:: <{ Q..

A small surface inlet will be installed at this low point and will be connected to existing storm sewer as shown in Exhibit D herein. Propo~ed tpp ,of pavement at this surface inlet {Pro;~"+ d v .. ~) is 90.0~. This regrading will increase the volume of existing basin no. 1 by approximately 500 cubic feet. The volume of existing basin no. 1 given in the Galindo Drainage Report is 17,000 cubic feet. A 6-inch by 6-inch square surface inlet is proposed. Maximum flow rate through this inlet with 1 foot of head is computed to be 1.2 cfs if not restricted down stream. to A 12-inch diameter pipe is proposed for drainingAthe proposed junction box at one of the two existing 42-inch storm sewer pipes denoted as culvert no. 1 in the Galindo Report. The flow line elevation is placed at mid height of the existing 42-inch pipe and flow in the 12-inch pipe will be restricted when the 42-inch pipe aRa flew iR ~ae 12 inch pipe will be re~erieeed when ehe 42 inch pipe is flowing near full. Therefore peak discharge from detention basin no. 1 will not be increased significantly but the basin wi11 eventua11y drain.

The purpose of this investigation was to core and measure the thickness of the existing concrete paving in several locations across the parking lot at this facility. We also visited the site to observe and comment on the staining that has occurred on the tilt-wall panels for the existing structures. Project Information The site of this investigation is l ocated on the southeast corner of the intersection of Southwest Park way and Texas Avenue in College Station, Texas. The property is occupied by an operating supermarket/retail center. The ·structures are tilt-walled construction with a painted finish. Concrete paving covers most of the remainder site. Site Observations Several types of distress were noted in the exist i ng concrete paving across the parking lot. These observations represe~t the most severely distressed areas observed during our visit, but were not meant to be a HOUS T ON e DAL LAS e A U S T IN e BEAU MONT • G ALV ESTO N COUNTY • R IO GRANDE VA LLEY • ALEXANDR IA SAN ANTONIO e FORT WO R T H e M IDLAND • MONROE• SHREVEPORT • TEXARKANA • DENISON • BATON ROUGE A m l~11 1tJcr ot the [HIH}';rouo of como,ir m~s SOUTHWESTERN LABORATORIES Paragon Group, Inc. Mr. Robert Austin Page 2 September 22, 1992 total survey of all distress in the paving. The approximate locations of these more severe areas of distress are shown on the attached Core Location Diagram. The type of distress at each location is indicated by the symbol on the diagram, and description of the distress is indicated on the Legend of Distress shown on this diagram. A brief description of each type of distress and applicable attached photographs of this distress are indicated below: 1. Longitudinal Cracks-pavement areas where cracks are long and continuous as noted in the pavement surface. In most cases, singular cracks or 2 to 3 parallel cracks were observed. (See Photo 1). 2. Subgrade Failure-Depressions in the paving causing numerous cracks in one local area. These depressions often result due to loss of support from the subgrade, resulting in settlement of the pavement surface and numerous broken pieces of concrete of various sizes. (See Photo 2 ) . 3. Ponding Water-Low areas where water accumulates due to rainfall, irrigation, etc. These areas have poor drainage due to grading during construction or settlement/heave after construction. (See Photo 3). 4. Curb Failure-Local sections of curb that have broken off or sheared. (See Photo 4). 5. Sp al 1 ing Concrete-Disintegration of the coarse aggregate/sand matrix on the pavement surface causing loss of surface thickness and rough appearance. (See Photo 5). In addition to the above observations, several locations of staining on the tilt-walled panels were observed during our site visit. Examples of this staining are shQWn in Photos 6, 7 and 8. SOUTHWESTERN LABORATORIES Para gon Group, Inc. Mr. Robert Austin Page 3 September 22, 1992 The staining most often occurred from isolated points on the walls, with a long streak of staining originating from each point and extending downward toward the paving. The most frequently stained areas occurred along the backsides of the structure, although this may be due to more frequent cleaning and/or painting of the more visible front areas. A pick-axe was used to chip-away the surface layer of paint and some of the concrete to further study these stained areas. The staining in freshly chipped concrete appeared to be present in the fine aggregate parts of the concrete mixture. Field and Laboratory Studies Southwestern Laboratories visited the site on September 3 and 4, 1992 to core the existing parking lot. Locations were selected by the field engineer for core sampling. A total of 13 locations across the parking lot were cored to obtain a representative sampling of the parking lot thickness and strength. The approximate location of these cores is shown on the attached Core Location Diagram. The 13 cores obtained from the existing concrete parking lot were returned to the laboratory for measuring and testing. The specific gravity and unit weight of each specimen was determined and results of these tests are shown on Table 1. Twelve of the thirteen cores obtained from the existing parking lot were suitable for compression testing based on length to diameter ratio. The unsuitable core (No. 11), would have had a sawed length to diameter ratic less than 1 which was considered to short for compression testing. In selected core locations, the subgrade soils were sampled directly beneath the paving. These subgrade soils were tested with phenolphthalein to determine if they contain hydrated lime used for stabilization. These samples were returned to our laboratory for testing. SOUTHWESTERN LABORATORIES Paragon Group, Inc. Mr. Robert Austin Page 4 September 22, 1992 Atterberg Limits tests were performed on selected samples of the subgrade soils to classify the soils. Minus 200 sieve analyses were also performed on the more sandy soils for classification purposes. Results of all tests (field and laboratory) are presented on the attached Table 3. Summary of Compression Test Results Results of compression testing are presented on the attached Table 2. This table also presents the measurements of each core specimen, the lengt:h to diameter ratio and the maximum load applied to each specimen. Core lengths ranged from 4. 2 to 5. 4 inches, with the exception of Core No. 11 which was 4 inches long and was unsuitable for compression testing. Results of the compression tests indicated strength values ranging from 3,990 to 7,220 pounds per square inch. Iron Staining-Cause and Repair There are several typical causes for the type of staining observed at this site. The two most common are rusting reinforcing steel and the hydration of iron pyrites found near the concrete surface. After close visual examination, it appears that the major contributor to the staining observed was the presence of what is thought to be iron pyrite. Many of the staining source locations were no longer covered with paint. This is attributed to the expansion of t he iron pyrite resulting in what is commonly called a pop-out (Photo 6/7). Once the surface is exposed to wetting cycles, staining becomes an ever increasing problem. Due to the age of this structure, it is probable that the problem areas are now exposed. The longer rust stains remain the more difficult they are to remove. However, because this is a painted structure, the rust stains may be more easily removed by removing the effected paint. There are several methods to minimize the effect of the staining material. The most effective is to eliminate the source. This can be accomplished by chipping out the source spot until clear concrete is found. A quality patch can then be installed in the area of repair. SOUTHWESTERN LABORATORIES Paragon Group, Inc. Mr. Robert Austin Page 5 September 22, 1992 Because this structure is painted, the color of the patch should not be of major concern. However, it is imperative that the patch be of high quality and properly bonded tq prevent possible effects from future freeze thaw cycles. Quality patching material can be purchased for companies such as SIKA Corporation (1-800-241-4372) or CORMIX Construction Chemicals ( 1-800-444-4047) and should be installed by a qualified technician. If you choose to remove the surface stain only, SwL will furnish you with a copy of a procedure found in Concrete Construction Handbook, Second Edition by J. J. Waddell. The referenced procedures requires skill and attention to detail and is not recommended unless an exposed concrete surface has been effected by the stain, not the case here. We trust this information will be of benefit to you on this project. If you have any questions or we can be of further assistance, please contact this office.
