Demolition and site work for a development in Otsego Township, Michigan. Completed plans call civil work for a conservation development.

An existing 25,000-gallon aboveground storage tank (AST) present at the site has subsided since its installation in 2004. The settlement has caused the eastern end of the AST to be approximately 2.5 feet lower in elevation than its western end. The scope of work includes the removal and disposal of the AST as well as other items detailed below. The historic contents of the AST have been limited to condensate water that is a byproduct of the site's landfill gas collection system. The contents of the AST have been pumped out. An EGLE contractor completed a system startup/test and AST content inspection on May 8, 2026. All blowers, pumps, and electrical equipment were verified to be operational during the inspection. The interior of the AST was observed to be dry and free of sludge or solids during the inspection. A copy of the inspection will be provided to the selected contractor. The primary project activities will include: disconnection and disposal of the remediation system (RS) piping from the air water separator knockout tank to the AST, removal and disposal of the 25,000-gallon AST (including all insulation systems, connection piping [vent, manway, gauge, fill, discharge quick connect, irrigation line/pump, thermocouple, heater]), AST ladder/platform, and two (2) AST saddles. Heat tape is present on the piping from the automatic water separator (AWS) transfer pump to the AST. The piping should be capped above grade, near the AWS transfer pump. Removal and disposal of the piping assembly connecting the AST to the air water separator knockout tank. Removal and disposal of irrigation pump connected to the AST, cap connective piping, and properly terminate electrical connections. The contractor shall dispose of this piping and heat tape. Replacement of the insulation on the blower inlet piping will not be required. Removal and disposal of unused hoses present on the equipment pad. The AST concrete footers will remain in place. Once the AST has been removed, the surface cover at its former location should be restored only by smoothing out the existing surface cover. The reinforced, subgrade, concrete foundations supporting the present AST will remain in place and the contractor will finish the saddle structures to a depth below the finished ground surface. Resurfacing of the AST area may be completed by the contractor if deemed necessary to facilitate installation of the new equipment concrete pad, located adjacent to the location of the former AST. Installation of a level, 60-foot-long by 20-foot-wide level, compacted gravel pad located outside the remediation system perimeter fencing, adjacent to the north side of the AST perimeter fencing. The gravel pad will be constructed and compacted using a material type and thickness to be suitable for the weight of a 21,000-gallon trailer-style fractionation tank filled with water. Remove and replace an existing equipment pad adjacent to the AST which has subsided in a similar fashion as the AST. The equipment pad is an approximately 12 inches thick concrete pad measuring approximately 43 feet long by 15 feet wide. The equipment pad contains two blowers and ancillary electrical equipment, header pipes, and a discharge stack (existing equipment). The contractor will remove all equipment on the pad, demolish the pad and dispose of the demolished concrete at a recycling facility. The contractor will regrade the area level with installation of a new compacted subbase at the same location as the existing pad. The contractor will then replace the equipment pad with a new concrete pad in the same location as the current equipment concrete pad. The contractor will not replace approximately 20 feet of the western portion of concrete pad formerly occupied by the carbon vessels. The new equipment concrete pad will be approximately 6 to 8-inches in thickness. The contractor will then reinstall the existing equipment. The contractor will remove and dispose of the chain-link and wooden fencing surrounding the AST and its ancillary equipment. The length of the fencing surrounding the AST and its ancillary equipment is estimated to be 250 feet. Existing fencing will be stockpiled onsite and disposed of at an appropriate facility by the contractor. The contractor will supply and erect a temporary 6-foot chain link construction fencing to replace the portion of the removed fencing structures. The length of the temporary fencing required is estimated to be approximately 120 feet. Upon completion of the AST removal and other scoped activities, the contractor will remove the temporary fencing and install permanent perimeter fencing in the same location as the former perimeter fencing. The new perimeter fencing will be approximately 10 feet in height with an estimated length of 250-feet, and be fitted with two gates of the same width, type, and locations as that of the removed fencing. The new perimeter fencing will include privacy slats on the west and south sides of the perimeter fencing. Question Deadline 06/02/2026 at 2:00 PM ET All requests or inquiries concerning the Bidding Documents, or the Work must be addressed to: Mike Cox at mike.cox@aecom.com. The Work to be completed for this Project consists of furnishing all labor, materials, earthwork, construction operations, details, supervision, and coordination of all trades, utility suppliers, governmental inspections, and approvals to complete the construction, installation, and coordination for the City of Dacula "Brookton Chase Court and Brookton Downs Subdivision Asphalt Repaving Project" as follows: The scope of work for Brookton Chase Court includes performing Full Depth Reclamation (FDR) which requires milling 3-1/2" of existing asphalt and subgrade material; then mixing Type I Portland Cement at a spread rate of 65 lbs/sy. Contractor will then install 2" of 19mm asphalt binder course; apply tack coat and then top with 1-1/2" of Type 2 - 'F' Mix (9.5mm) surface course asphalt pavement. Contractor shall re-establish crown in center of road when installing pavement to promote positive drainage to existing curb & gutter and storm drainage inlets. Existing asphalt cores based on SGC report reveal asphalt thicknesses of 1-1/2"" to 2-1/2". Brookton Downs Subdivision consists of Brookton Drive, Brookton Lane, and Brookton Woods Way. Brookton Drive and Brookton Lane have been repaved multiple times over the years, so asphalt is built up above the gutter line. Existing asphalt cores based on SGC report reveal asphalt thicknesses of 3-3/4" to 5". Contractor will utilize variable depth milling to re-establish crown in center of road and to achieve proposed pavement that is flush with gutter line. A tack coat will then be applied prior to installing 1" of 'D' mix asphalt binder course pavement. An additional tack coat will then be applied prior to installing 1-1/2" of Type 2 - 'F' mix (9.5 mm) Surface Course Pavement over the entire streets. In addition, on Brookton Drive at about Station 1+50 the pavement has been lifted by what appears to be tree roots. Existing asphalt shall be deep patched milled an additional 6" to clear any tree roots, then filled with 25mm superpave asphalt prior to variable milling and repaving as described in paragraph above. Approximate deep patch milled area is marked by city with orange paint. Brookton Woods Way existing asphalt appears flush with gutter line but will also need variable depth milling to re-establish crown in center of road and to ensure proposed pavement is flush with gutter line. Existing asphalt cores based on SGC report reveal asphalt thicknesses of 3"" to 3-1/2". Once milling is complete, contractor shall install a tack coat and then install 1" of 'D' mix asphalt binder course pavement. An additional tack coat will then be applied prior to installing 1-1/2" of Type 2 - 'F' mix (9.5 mm) surface course pavement over the entire street. Contractors shall visit the streets identified to determine their own quantities for bidding the project. Orange paint markings on Brookton Chase Court shall be ignored since entire street will undergo FDR. The project service area includes improvements for the entire length of Brookton Chase Court (approximately 2,016 L.F +/-), Brookton Drive (approximately 1,268 L.F. +/-), Brookton Lane (approximately 1,733 L.F. +/-), and Brookton Woods Way (approximately 519 L.F. +/-). All streets are approximately 24' wide from edge of pavement to edge of pavement with 80' diameter cul-de-sacs. LMIG, LRA, and SPLOST funds will be utilized by the City of Dacula for the scope of work to improve these city streets. Contractor is responsible for complying with all regulations and providing all documents as per City of Dacula requirements. A Pavement Evaluation Report for the Subdivision has been completed and provided by Southern Geotechnical Consultants (SGC) as previously mentioned to determine the existing asphalt and base thicknesses and condition of soil subgrade.
