Ensure deflection and deformation under load are minimal but allowed for so that the completed concrete is within the specified tolerances. F. Make formwork for beams and slabs so that the forms for the sides of the beams and for the soffits of slabs can be removed without disturbing the forms for the beam bottoms or the props under the beam bottoms. Either support vertical props on wedges, or employ other measures whereby the props can be gently lowered vertically when commencing to remove the formwork. G. Form openings as necessary for cleaning and for inspection within the formwork. Close the openings before concrete placing. H. Tighten forms to close all joints. Align and secure joints to avoid offsets. I. Foran 1 in. by 1 in. chamfers on the external corners of all concrete except where the Drawings require otherwise. 3.4 WOOD FORMWORK A. Use plywood or other approved panel for formwork throughout except where "boardmarked concrete" as required on the Drawings. 3.5 APPLICATION — FORM RELEASE AGENT A. Apply form release agent on formwork in accordance with manufacturer's recommendations. B. Apply prior to placement of reinforcing steel, anchoring devices, and embedded items, C. Do not apply foil release , agent where concrete surfaces will receive special finishes or applied coatings which are affected by agent. Soak inside surfaces of untreated forms with clean water. Keep surfaces coated prior to placement of concrete. D. Apply form releasing agent to faces of formwork in contact with concrete. E. If concrete is to remain exposed, use the same form releasing agent for all applications. SE Samuel Engineering, inc.

Surface irregularities shall not exceed 1/4 inch for abrupt irregularities and 1/2 inch for gradual irregularities. 3. Finish F3 applies to formed surfaces, the appearance of which is considered by the Engineer to be of special importance, such as surfaces of structures prominently exposed to public inspection. Surface irregularities shall not exceed 1/4 inch for gradual irregularities and 1/8 inch for abrupt irregularities, except that abrupt irregularities will not be permitted at construction joints. 4. Finish F4 applies to formed surfaces for which accurate alignment and evenness of surface are of paramount importance from the standpoint of setting equipment and maintenance of specified clearances. Abrupt irregularities shall not exceed 1/4 inch for irregularities parallel to the direction of flow, and 1/8 inch for irregularities not parallel to the direction of the flow. Gradual irregularities shall not exceed 1/4 inch. 5. Special Finish BFT applies to the formed surfaces designated on the architectural drawings or in the interior finish schedule to receive a board form texture finish. Except for the formed grooves, cone holes and the V- shaped fins, surface irregularities shall not exceed 1/4 inch for gradual irregularities and 1/8 inch for abrupt irregularities. Abrupt irregularities will not be permitted at construction joints. D. Upper Surface Finishes 1. Screeded finish is for surfaces of roads or of foundation beds, slabs and structural members to be covered by backfill, subsequent stages of construction, bonded concrete topping or cement mortar beds to receive pavings, and on exposed surfaces of paving where a superior finish is not required. The finished operations shall consist of levelling and screeding the concrete to produce a uniform, plain or ridged surface, with surplus S:1Projects\4107.011 SPECIFICATIONS103300 Cast -in -Place Concrete.doc REVISION 0 $E Samuel Engineering, Inc.

The purpose of the site inspection was to determine if the foundations were built in accordance with the engineered foundation plans. The Middle Fork electrical buildings were installed in October 2006, and October 2008. These buildings house the main breaker panels that distribute power from the primary electric supply lines to the Middle Fork area gas drilling operations, north of Parachute, Colorado. The foundations inspected are for two electrical buildings, PDC 1 and PDC 2. These buildings are modular units placed end to end on top of concrete piers that rise from spread footings below grade, The piers rise approximately five to six feet above grade, this distance varies slightly as the grade slopes downward toward the west. The lower building frames consist of structural steel channels that are welded together. The channel frames are attached to the concrete foundation piers by 3/4 inch diameter anchor bolts which are embedded into the piers. The upper structure attaches to the channel frames to form the complete modular unit. The modular units are designed to be lifted by cranes, and set onto the tops of the foundation piers as whole units. Inspection of the building structure is not in the scope of MI'A's inspection. Because concrete for the foundations had already been placed when MPA conducted the foundation inspection, it was not possible to verify rebar size and placement. Our inspection was limited to a visual assessment of the installed foundations above grade and building attachment. The inspection included review of foundation design drawings, field measurements to verify pier location dimensions, examination of the piers and building frames to check for signs of settlement or other indications of structural failure, building attachment to the piers, and the overall performance of the foundations. The foundation drawings for this project are listed in Appendix "A". During our inspection, the following observations were made: 1.) At the center pier at the eastern end of the eastern electrical building, at gridline C-25 on drawing 001 - CD -103, the bottom of the channel frame was not in contact with the top of the foundation pier. 2.) Many of the anchor bolts for the west building did not have nuts on the anchor bolts, and the building was held down by gravity only at these locations. 3.) The anchor bolts were the correct diameter, and were approximately at the locations shown on the drawings, although there was some slight variance in locations. Page 1 of 3 4.) The piers were located correctly per the dimensions on the foundation design drawings. 5.) The size and orientation of the piers was correct as per the foundation design. drawings. 6.) The lower spread footings were below grade, and could not be inspected. 7.) There were no indications of excessive settlement visible in the foundations or the lower building frames. 8.) There were no indications of excessive settlement in the interiors of the buildings such as diagonal cracks in the building walls, doors that were difficult to open, or any other visual signs. To correct the discrepancies found, the following corrective actions need to be performed: 1.) The center pier on the eastern end of the eastern electrical building at gridline C-25, drawing 001 -CD - 10, needs to have structural non -shrink grout placed between the top of the pier and the bottom of the frame to provide a proper bearing surface. 2.) The anchor bolts with missing nuts on the western electrical building need to have washers and nuts installed m accordance with the foundation design drawings. 3.) All anchor bolts need to be thoroughly inspected for missing or loose nuts and washers, any defective locations need to be corrected by installing nuts and washers where missing. All anchor bolts need to be checked for proper tightening. Overall, the foundations appeared to be structurally sound, and built in accordance with the design drawings, to the extent that could be visibly verified. These building foundations have been in place for several years and do not appear to have any indication of structural failures. Sincerely, MPA Consulting Engineers, Ince Don Howanick; M.S., P.E.
