Storm Sewer and Structures

GRIMES ROAD WORK CONTINUES BETWEEN BORES

| Chris Mattson

With the completion of the jack and bore crossing under Wolverine Pipe Line utilities, contractors on-site continue with work items southward along Grimes Road. Jackson Dirt Works resumed pipe installation, connecting to the newly bored steel pipe with manhole structures. Their pipe installation efforts take them south toward the location of the next jack and bore crossing.

Lowe Construction has been working to prepare the next jack and bore crossing under Enbridge Energy utilities. Extensive coordination and preparation has been undertaken to ready the site for the crossing work including phone and power utility relocation, temporary fencing, and deep and shallow dewatering systems. Dewatering efforts will be managed for the next 7-10 days, ahead of the crossing which is planned to commence the week of October 25, weather dependent.

If you have any questions or concerns, please contact Terry Belill, inspector, 989-996-5228.

JACK AND BORE CROSSING IN GRIMES ROAD

| Chris Mattson

Jack and bore crossings of petroleum pipelines began last week and were completed Monday, September 20. This is the first of two jack and bore crossings to be completed on the project. Lowe Construction was on-site to perform the work. A 48″ diameter steel pipe was bored under the Wolverine Pipe Line utilities to provide for a trenchless crossing. Safety coordination and utility representative oversight was top priority as the work progressed. This crossing was completed safely and without incident.

Storm sewer installation will continue to connect the bored steel pipe to the already installed portion of the relocated Bauer Drain. Preparations will begin within the next week to perform the remaining jack and bore operation under petroleum pipelines on the other portions of the project.

If you have any questions or concerns, please contact Terry Belill, inspector, 989-996-5228.

WORK WITHIN GRIMES ROAD PROGRESSING

| Chris Mattson

Work is progressing satisfactorily to construct the relocated Bauer Drain within Grimes Road. Crews have been diligently installing the 48-inch diameter storm sewer, manhole structures, and the base material for the restored roadway. Grimes Road is still closed and will remain closed until the pipe installation is complete. A posted detour route via Mt. Pleasant Road is in place and can be found on our Project Maps page.

In addition to pipe installation, crews are also preparing for the trenchless crossings under critical petroleum pipelines. All of the petroleum pipelines are being positively identified ahead of time by means of hydro-excavation so that we may safely cross under the critical utilities. On-site personnel is working closely with pipeline safety representatives as the crossings work approaches.

If you have any questions or concerns, please contact Terry Belill, inspector, 989-996-5228.

GRIMES ROAD WORK RESUMES

Drain relocation progress.

Nearly 800 feet of storm sewer and two drainage structures were installed last week on the Bauer Drain Relocation project. Crews worked within the drain easement east of the Grimes Roads, through an open agricultural field. There was one day lost to weather last week, however, construction crews are already back to work this morning, hoping to near Grimes Road by the end of this week, weather dependent. Once work items progress into Grimes Road, the road will be closed until work is complete. More information to come on the Grimes Road closure.

BAUER DRAIN STORM SEWER PROGRESS

| Paige Kipp

Construction crews began installing 48-inch round storm sewer this week after the completion of elliptical pipe installation. Restoration of previous work areas has been completed in an effort to reestablish vegetation. Progress will continue this week pending any delays from the rain in the forecast.

If you have any questions or concerns, please contact Terry Belill, inspector, 989-996-5228.

PROGRESS CONTINUES FOLLOWING WEATHER DELAYS

Elliptical pipe progress.

Elliptical pipe installation continues on the Bauer Drain Relocation project. The crews are making good progress this week following significant weather delays before the Fourth of July holiday. From June 25-27, approximately 4.2 inches of rain fell at the Bauer Drain project site. This amount of rain was equal to a storm that may statistically occur once every 10-25 years.

The elliptical pipe installation is scheduled to complete this week, and the crews will continue to conventional storm sewer installation, working west towards Grimes Road. The crews will also be mobilizing within the next week to the Sycamore Creek stream mitigation portion of the project in the City of Mason.

If you have any questions or concerns, please contact Terry Belill, inspector, 989-996-5228.
