The purpose of this project is to improve wetland and drainage conditions in the SR 167
vicinity. This will be accomplished by constructing a new SR 167 cross culvert, adding
a utility vault weir structure and plugging several, poorly-functioning cross culverts.
The Design Documentation File was submitted on January 20, 1998 and approval is
pending. The Soils Report was approved on March 4, 1997.
The City of Renton is obtaining the two environmental permits required for this project.
This culvert construction is in conjunction with a flood control project that the City is
constructing. The EIS was approved in September 1997. The Joint Aquatic Resource
Permit Application(JARPA) was filed with the Corps of Engineers and the Department
of Fish and Wildlife on December 31, 1997. We anticipate receiving the HPA by mid-
March 1998. The 404 permit from the Corps was approved January 13, 1998. A noise
variance has been requested from the City of Renton on March 6, 1998, and a public
hearing will be scheduled shortly.
We are awaiting an agreement with the City of Renton for the maintenance of the vault
control structure and for their participation with funding to reestablish the channel
between East Valley Road and SR 167 right of way.

Temporary construction easements with Olympic Pipeline, Strada DaValle Company and
the City of Renton have been requested, however, not yet received. We anticipate
receiving these construction easements by mid-April.
Unique to this project is the introduction of trenchless technology. Pipe ramming will be
included for bid as alternative A2. A performance specification has been included for
pipe ramming. . The open cut construction method has been included for bid as
alternative Al.
The data used to determine the estimate cost for lump sum bid items or other bid items
that have little or no historical cost data is attached.
The critical path method for computation of the number of working days for this project
is attached.

1 2. Shall meet the requirements of the contract and be approved by the
2 Engineer;
3 3. May be inspected or tested at any time during their preparation and
4 use; and
5 4. Shall not be used in the work if they become unfit after being
6 previously approved..
7
8 1-06.1(1) Qualified Products List (QPL)
9 The QPL is a listing of manufactured products that have been evaluated and
10 determined suitable for use in highway construction.
11
12 If the Contractor elects to use the QPL, the most current list available at the
13 time the product is proposed for use, shall be used. The QPL submittal shall be
14 prepared by the Contractor in accordance with the instructions in the QPL and
15 submitted to the Engineer prior to use.
16
17 The QPL identifies the approved products, the applicable specification section,
18 and the basis for acceptance at the project level. The listing is divided into two
19 categories, "Approved" and "Conditionally Approved". "Approved" products are
20 denoted with an "A". Those products may be accepted without additional
21 sampling. "Conditionally Approved" products are denoted with a "CA". The
22 acceptance and use of these products is based upon additional job sampling
23 and/or documentation. All additional acceptance actions need to be completed
24 prior to the material being incorporated into the work.
25
26 The Contractor shall advise the Engineer of the intended items for use from the
27 QPL by reference to the contract bid item.
28
29 The use of listed products shall be restricted to the Standard Specification for
30 which they are listed and fulfillment of the acceptance requirement defined in
31 the QPL. Qualified products not conforming to the specifications, not fulfilling
32 the acceptance requirements, or improperly handled or installed, shall be
33 replaced at the Contractor's expense.
34
35 To qualify for continued listing on the QPL, products may be sampled and
36 tested for conformance to the Standard Specifications. The Contracting
37 Agency reserves the right to make revisions to the QPL at any time.
38
39 If there is a conflict between the QPL and the contract, the provisions of the
40 contract shall take precedence over the QPL.
41
42 1-06.1(2) Request for Approval of Material (RAM)
43 The RAM shall be used when the Contractor elects not to use the QPL or the
44 material is not listed in the QPL. The RAM shall be prepared by the Contractor
45 in accordance with the instructions on the form (DOT 350-071) and submitted to
46 the Engineer for approval before the material is incorporated into the work.
47
48 Approval of the material does not constitute acceptance of the material for
49 incorporation into the work.
50
51 Additional acceptance actions as noted on the RAM need to be completed prior
52 to the materials being incorporated into the work.
53
54 When requesting approval of an item that requires fabrication, both the
55 fabricator and the manufacturer of the base material shall be identified on the
56 RAM.
57
58 1-06.2(1) Samples and Tests for Acceptance

4
5 The Contractor may request, in writing, authority from the Engineer to install
6 such materials prior to submitting the required certification; however, no
7 payment will be made for the work in the absence of an acceptable
8 Manufacturer's Certificate of Compliance. The Contracting Agency reserves
9 the right to deny the request for good cause. If for any reason the Contractor
10 has not provided an acceptable Manufacturer's Certificate of Compliance by the
11 physical completion date established by Section 1-08.5, the Contracting
12 Agency will assess the usefulness of the installed material. At the Engineer's
13 discretion, the Contracting Agency will either require replacement of the
14 material by the Contractor at no expense to the Contracting Agency or process
15 the final payment as provided by Section 1-09.9 without paying for the materials
16 or any portion of the work performed to install the materials provided on such a
17 basis. The unit contract prices for the work shall be used to determine the
18 amount to be withheld. Where unit contract prices do not exist, as in a lump
19 sum item, the amount to be withheld shall be an equitable adjustment, covering
20 labor, equipment and materials, determined in accordance with Section 1-09.4.

50 expense. The Contractor shall be responsible for scheduling when to
51 renew striping, subject to the approval of the Engineer. When the
52 scope of the project does not require work on the roadway, the
53 Contracting Agency will be responsible for maintaining the striping.
54
55 4. Maintain existing permanent signing. Repair of signs will be at the

22
23 5-04.3(10)B Control
24 The third paragraph is revised to read:
25
26 At the start of paving, the Contractor must demonstrate to the Engineer that the
27 mix is compactible by constructing compaction test section(s). Test section(s)
28 shall be constructed using the compaction train and a variety of rolling patterns
29 that the Contractor expects to use in the paving operation. A test section will be
30 considered to have established compactability, based on the results of three
31 density determinations, when the average of the three tests exceeds 92% of
32 Rice or when all three tests individually exceed 91 percent of Rice. This will
33 require consideration of the presence of a correlation factor for the nuclear
34 gauge and may require final resolution after the factor for the gauge is known.
35 A minimum 1.00 compaction pay factor shall be used until a gauge correlation
36 factor is known, and until the mix is considered compactible. When
37 construction of the test section(s) has demonstrated that the mix is not
38 compactible, paving must stop. To resume paving, all factors contributing to
39 compaction shall be analyzed and Engineer approved changes made, which
40 may require a new mix design. When paving is resumed the Contractor must
41 again, as previously defined, demonstrate that the mix is compactible. If the
42 Contractor does not construct test section(s) the mix is considered compactible
43 and all mix placed will be evaluated according to Section 5-04.3(10)B.

38 Approval of Subcontractor or Contractor
39 The Contractor or subcontractor performing the work described in these
40 Special Provisions, which is involved with furnishing, installing 72 inch diameter
41 steel casing by pipe ramming with a pneumatic pipe rammer designed and
42 fabricated for ramming casing pipe, shall provide references and resumes of
43 staff that shall meet the following requirements:
44
45 The firm installing the casing must have experience with the pipe ramming

47 200 feet and two at least 100 feet in length and all four at least 36 inch
48 diameter. The 200 and 100 foot requirement means that during the installation
49 of a single casing pipe the casing was pushed for a continuous distance of 200
50 or 100 feet using pipe ramming.
51
52 Examples:
53 • Five installation of 40 foot casing at different locations on a single
54 project does not qualify for the installation of 200 feet of casing.
55
56 • A casing in which the first 40 foot casing section was installed by pipe
57 jacking, then the next 200 feet of the same casing was installed by pipe
58 ramming, and then the final 50 feet of casing was installed by hand
59 tunneling and jacking qualifies for installing 200 feet of Casing using
60 pipe ramming.

2 A Contractor installs 200 feet of casing using standard jacked casing
3 and augering on a 300 feet casing project then gets stuck. Pipe
4 ramming is used to free the stuck casing and complete the project.
5 This does not count as 200 feet of experience because only 100 feet
6 was installed using the pipe rammer. If the project was 400 feet long
7 and the pipe rammer finished the last 200 feet of installation, it would
8 count as experience using pipe ramming.

Subject: SR 167
Sorry for the confusion, everyone, but it turns out that WSDOT must acquire temporary easements from Strata da
Valle and Olympic Pipe Line Company (along with the Letter Construction Permit from City of Renton) to construct
the culvert on adjoining State property, AND must acquire permanent easements from City of Renton, Strata da
Valle and Olympic Pipe Line Company for access to maintain the culvert on adjoining State property. (The City
can't give WSDOT permission to work on other people's property. We need to acquire our own rights.)
So, in conclusion, 3 permanent easements and 2 temporary easements (to be acquired by Real Estate Services)
and a Letter Construction Permit(to be drawn by TransAid) necessary before project can be certified.

Okay, good, talked with Hq, the only concern is that the Contractor be provided a boring log, H-2-97, 1120+90, 70'
Rt should suffice for this purpose, if you need a copy give me a call but you should have it.

Neil, the sheet piling for the fish ladder have no load, they serve as wall. There will be a headwall at the end
of the culvert connecting the the fish ladder. I will fax you the design we got from Renton for additional
information.
Thank for your help.

LABORATORY TESTING
Laboratory testing was performed on selected samples from the field exploration program.
All disturbed soil samples were visually examined and then grouped together based on
particle size distribution, consistency, and color. Once groups of samples were established
that had similar characteristics, a minimum of one sample per group was tested. The testing
consisted of performing particle size analyses, determining the liquid limit if applicable, and
determining thQ plastic limit and plasticity index if appiicable. The tests were done in
accordance with A-ASHTO T-88, T-89. and T-90 guide specifications respectively. After the
testing was complete, the samples were classified using the Unified Soil Classification
System (USCS).
The results of all laboratory testing are attached in Appendix B.
PROJECT SOIL CONDITIONS
The soil materials encountered during the field investigation have been grouped into four
general soil units based on engineering properties and material classifications. The units are
briefly described below:
Unit 1 Fill - loose to medium dense, well graded sand to silty sand with
gravel.
Unit 2 Soft peat and organic silt with wood fragments.
Unit 3 Soft sandy silt to elastic silt with an intermediate medium dense, silty
sand layer. The intermediate layer consist of volanic debris which
varies in thickness between 4 ft and 7 ft under the culvert.
Unit 4 Medium dense to dense, interbedded lavers of well graded sand and
gravel to silty sand.
In general, Unit 1 is underlain by Unit 2, which is underlain by Unit 3. Unit 3 is underlain by
Unit 4. The flow line (bottom) of the culvert varies between elevation 9.0 ft and elevation
John Johnson/R. Suafoa
March 4, 1997
Page 3
7.0 ft. The flow line is located near the Unit 1 and Unit 2 contact. Unit 2 soil will be
encountered under the flow line of the culvert. The thickness of the highly compressible
organic soil (Unit 2) varies between 3 ft to 10 ft under the culvert. Soil Unit 3 is
approximately 17 ft thick.
GROUND WATER
Ground water was encountered at varying elevations at the time of field exploration. Ground
water was seen at approximate elevation 12 ft west of SR-167 and at approximate elevation
14 ft east of SR-167 on January 10. 1997. Ground water was encountered in test boring
B-11-93 at approximate elevation 6.5 ft west of SR-167. Ground water was seen at
approximate elevation 8.5 ft in test hole H-10-93 east of SR-167. Both test holes (B-10 and
B 11) were drilled on February 25. 1993. The ,`.field exploration was conducted during the wet
time of the year. We expect that the water will vary seasonally. We recommend that the
culvert be excavated during the dryer time of the year between July to October.
GEOTECHNICAL RECOMMENDATIONS
A 230 ft long, 84 inch round culvert is proposed in the vicinity of project Station L 1120+80.
The flow line (bottom) of the culvert varies between elevation 9.0 ft and elevation 7.0 ft. The
flow line is located near Unit 1 and Unit 2 soil contact. The amount of cover over the
culvert and the roadvmy will be between 8 ft and 10 ft. The new culvert site is located south
of existing utilities. The utilities are overhead power lines, oil/gas pipe lines acid buried
waterlines. The buried oil/gas lines are approximately 70 ft from the new culvert.
Pipe jacking is not considered feasible for the diameter and length of the proposed culvert.
We are concerned with the integrity of the existing roadway if pipe jacking is used. The
following are some of reasons that pipe jacking should be removed from consideration:
1. The site of the proposed*acking pit will be located on soft soil with a high ground water
table.
2. The pit would require some "impermeable" enclosed cell or cofferdam with a pile
supported reaction frame in order to push the culvert.
3. Dewatering should not be alloy ed. if dewatering is allowed for construction of the
culvert. damage to the roadwav and existing utilities is likely. Changes in ground water
Will induce settlement under the existing roadway embankment. Settlements up to a foot
are possible if dewatering is allowed.
4. The mixed-face conditions (e.g. part of the heading will be in relative high quality
embankment materials, while the bottom will be in soft pears and organic silts) will likely
create construction problems. This will affect the control of grade of the culvert and the
probability of a potential cave in.
5. The small amount of cover in relationship of the pipe diameter could create a sink hole
which would propagate rapidly to the driving surface.
We recommend that cut-and-cover construction methods be used.
John Johnsori%R. Suafoa
March 4. 1997
Page 4
The flow line (bottom) of the pipe will be at an elevation where up to 7 ft of peat and organic
silt (Unit 2 soils) currently exist. We recommend over-excavating a minimum of 2 ft below
the culvert. The over-excavation section will provide a stable base for the bedding/
construction surface for the culvert. We recommend a laver of high-strength geotextile as a
separation barrier between the organic soil and new backfill. The geotextile should meet the
requirements for Soil Stabilization in Section 9-33 in the Standard Specifications. The over-
excavated cavity should be backfilled with shoulder ballast. The top of the shoulder ballast
should be choked with gravel backfill for pipe zone bedding. We expect that ground water
will be encountered during the.construction of the trench. As previously discussed, the water.
table is seasonally variable. -We expect up to 6 ft of water could be encountered during
construction.. During the dry part of the year, the water table should be lower, but'2 ft or
more of water may be encountered during construction.
.fhe"toial settlement of the new foundation will be equal to or less than 2.0 inches. The
6#fer=tial settlement-along the culvert will be less than one inch.
CONSTRUCTION CONSIDERATIONS
Construction cor,.si.derations that will require attention during design and construction of this
project are as follows:
1. Temporary shoring may be needed to preserve the existing adjacent roadway. We
expect that the-culvert will be built in sections while crossing SR-167.
Please dote that the determination of the actual slope used for temporary excavation IS
the responsibility of the contractor. The contractor will have control over factors
which affect the stability of the excavation slope, such as length of exposed slope,
length of tirne the excavation is left open, and the exposure to inclement weather.
2. Ground water may be encountered during trench construction. Dewatering is not
recomniended, due to potential settlement caused by the sudden drawdown of the
ground water. Ground water is expected to vary both seasonally and in response to
inclement weather changes. Ground water varied up to 7 ft as seen from the field
observations and in the existing test borings.
3. We recommend that a Summary of Geotechnical Conditions be included in the
contract documents to identify potential construction difficulties. This document will
be prepared by our office at the time of the final PS&E review.
CLOSURE
Logs of Test Borings, laboratory test data are included in Appendices A and B, respectively.
