RE:
Proposed Scope and bid of Work for SFMTA, Third Street Light Rail Program,
Phase 2 - Central Subway Chinatown Station Contract 1254
Hayward Baker (HB) is pleased to propose on the Compensation Grouting Section 31 43 14 (see attached
Bid Items) of the referenced project. We have visited the site, reviewed the plans, specifications and
addenda (thru #6). The “suggested grout pipe layout schematic” on drawings BP101-103 is the basis of
our costs. The final design is the responsibility of the specialty contractor and upon award discussions
regarding probable settlements from SEM will be needed to finalize the design. Based upon available
information it is anticipated additional holes and monitoring points (drawing BP011) will be needed, and
will be added costs at the unit prices below.
As discussed in the meeting the headhouse excavation will be stopped at approximately El. 90 for the
drilling and grout pipe installation. Utilizing 2 rigs 2 shifts we will need 8 to 10 weeks to complete. A
minimum 8 feet wide “cat walk” working platform along the wall and holes will be needed to complete the
pre-condition and the cavern excavation compensation grouting. Understanding staging area is critical, we
can compact our operations in a minimum area 20 by 30 feet by stacking containers 3 high.
In addition, HB can provide Jet Grouting and Permeation Grouting services as requested for the SEM
work. We can supply either or both cement, microfine or chemical penetration grouting.
Compensation Grouting
Items included in our proposal for this project are as follows:
 All labor, equipment, materials, and supervision to perform the drilling and “sleeve port grout pipe”
(SPGP) installation,
 Procurement, software, and Installation of Liquid Level System (LLS) for heave monitoring (with
integration into global job computer data system),
 All labor, equipment, materials, and supervision to perform the precondition consolidation grouting,
 All labor, equipment, materials, and supervision to perform compensation grouting during SEM
cavern excavation and support work,
 Testing, quality control and quality assurance for the compensation grout work as described in the
contract specifications,
 Submittals and shop drawings required for our work.

Compensation Grouting Exclusions
Items specifically excluded from this proposal and to be supplied by others, at no cost to HB are as
follows:
 All concrete diaphragm wall knockouts and/or any coring required for SPGP installation,
 Any excavation support to install grout pipes & perform grouting,
 Access buy way of sidewalks and streets by crane service or other means at all times during, drilling,
grout pipe installation, preconditioning grouting and compensation grouting,
 Work platform for performing pre-conditioning and compensation grout injection from SPGP’s,
 Access to surrounding building exterior and interior lower floors for LLS instrumentation installation,
 Provision of a flat, level, stable work platform from which our operations may take place,
 Provision of water at a flow no less than 75 gpm at 50 psi for drilling and/or grouting.
 Provision of electric power up to 400 amp service at 440 volts,
 All lighting, ventilation, and noise control,
 Upon completion, SPGP removal / withdrawal, grout backfilling, & repair/seal of the diaphragm wall,
 Safety and sanitation facilities for workers,
 Any and all traffic control required for the work,
 Inspection, permits, and easements necessary to perform the work
 Additional items as further described in our general terms and conditions.
SUMMARY
HB believes that the compensation grouting process is ideally suited to the particular needs of this project.
HB has successfully utilized this technology for similar projects in the US and Europe on many occasions,
and can provide references and project lists upon request. Additionally, HB has the resources (equipment
and personnel) to adequately handle this work, and as the largest specialty foundation contractor in the
United States, we have the financial backing and bonding capacity necessary to complete this work.
Please find attached a list of HB completed soilfrac compensation projects.
HB includes the LLS monitoring in our proposal because it is critical to the control of our injection. We
have worked with GeTec (designer, manufacturer and setup) on over 8 major compensation projects to
date. Their system is capable of repeatedly providing data to 0.2 millimeters, which allows us not only
real-time settlement but also tells us if the settlement is slowing down or speeding up.
This letter and its attachments constitute HB's proposal and will be made a part of any contract between
yourselves and HB. The acceptance of the price of this Proposal shall evidence the concurrent
acceptance of all terms and conditions recited herein or incorporated by reference.
We have enclosed our Schedule of Prices and our General Terms and Conditions, herein. Our bonding
rate is one percent. If we can be of any assistance in clarifying any points in this proposal, please contact
us by phone or email below.
