Construction Plans

Preconstruction Planning

We can work with your existing architectural and structural team or help you assemble one. More than just giving prices we can assist in developing alternatives that suit your requirements, value engineering, entitlement issues, sustainability and phasing decisions on existing facilities. Having 'your contractor' there from the beginning helps to manage expectations of stakeholders, expedite the design and construction process and avoid unwelcome surprises.

We understand the importance of completing your project on time, under budget and to the quality you expect.

We can take your existing design and help value engineer and show you how to accomplish the finished product you desire at a much lower cost. Our experience and that of our team will save you money.



Tashcon Corporation brings a hands on perspective to the construction management table, providing a 360 degree view to projects, ensuring quality and cost effectiveness in a timely manner.

Our principal and senior project manager, Hal Mahon, has worked in the Bay Area construction industry for over 40 years and has been involved in virtually every facet of general contracting. From the beginning Hal was struck by the power and the sense of accomplishment in building. It has been a lifelong passion


He began in the trades in the late 1970’s quickly working his way through the carpenter’s apprenticeship training program, working on numerous projects as a superintendent and for the past 33 years has been a very successful estimator and project manager.

Tashcon Corporation is experienced in Green Building (LEED certified), wood frame, concrete, masonry, structural steel, concrete tilt up, warehouse, tenant improvement, industrial, hi tech, biopharmaceutical, clean room, data centers, mid rise and auto dealerships. Hal brings talent and dedication to everything we build.

At Tashcon, one thing we are  known for far and wide is….Hal always picks up his phone.  It may seem like a small thing but when you do it for more than 40 years clients learn to trust no matter the topic or challenge Hal will answer the phone.
